Morphological Assessment and Possible Clinical Implications of the Left Ventricle Papillary Muscles. Study in a Colombian Population Sample

SUMMARY: Papillary muscles in the left ventricle present multiple anatomic expressions that are relevant for medical fields focusing on the understanding of clinical events involving these structures. Here, the aim was to perform a morphological characterization of the left ventricle papillary muscles in a sample of Colombian population. In the study were included eighty-two hearts from male individuals who underwent autopsy at the Institute of Legal Medicine and Forensic Sciences in Bucaramanga, Colombia. In each heart was carefully performed a longitudinal incision on the obtuse margin to visualize the papillary muscles. Data set was registered, and analysis of the continuous and categorical variables was carried out. Single anterior papillary muscle was observed in 74 samples (90.2 %) whereas this represented only 48 specimens (58.5 %) for the posterior papillary muscle (p = 0.3). Mean length and breadth of the anterior muscle were 29.9 ± 4.94 and 11.74 ± 2.75 mm, and those for the posterior muscle were 27.42 ± 7.08 and 10.83 ± 4.08 mm. Truncated apical shape was the most frequent type observed on the papillary muscles, anterior 41 (50 %) and posterior 37 (45.1 %), followed by flat-topped in the anterior 25 (30.5 %) and bifurcated in posterior muscle 14 (17.1 %). A mean of 9.04 ± 2.75 chordae raised from the anterior and 7.50 ± 3.3 from posterior papillary muscle. In our study we observed a higher incidence of single papillary muscles and slightly larger dimensions than information reported in the literature. The anatomic diversity of the papillary muscles should be considered for the correct image interpretation, valve implantation and performance evaluation on myocardial ischemic events.

Los músculos papilares del ventrículo izquierdo presentan múltiples expresiones anatómicas que son relevantes para las áreas médicas que se centran en la comprensión de los eventos clínicos que involucran estas estructuras. El objetivo fue realizar una caracterización morfológica de los músculos papilares del ventrículo izquierdo en una muestra de población colombiana. En el estudio se incluyeron ochenta y dos corazones de individuos masculinos a los que se les realizó autopsia en el Instituto de Medicina Legal y Ciencias Forenses de Bucaramanga, Colombia. En cada corazón se realizó cuidadosamente una incisión longitudinal en el margen obtuso para visualizar los músculos papilares. Se registró el conjunto de datos y se realizó el análisis de las variables continuas y categóricas. Se observó un solo músculo papilar anterior en 74 muestras (90,2 %), mientras que este rasgo se presentó en 48 muestras (58,5 %) para el músculo papilar posterior (p = 0,3). La longitud y anchura media del músculo anterior fueron 29,9 ± 4,94 y 11,74 ± 2,75 mm, y las del músculo posterior fueron 27,42 ± 7,08 y 10,83 ± 4,08 mm. La forma apical truncada fue el tipo más frecuente observado en los músculos papilares, anterior 41 (50 %) y posterior 37 (45,1 %), seguido de la forma plana en los 25 anteriores (30,5 %) y bifurcada en el músculo posterior 14 (17,1 %). Una media de 9,04 ± 2,75 cuerdas elevadas desde el músculo papilar anterior y 7,50 ± 3,3 desde posterior. En nuestro estudio observamos una mayor incidencia de músculos papilares únicos y dimensiones ligeramente mayores que la información reportada en la literatura. La diversidad anatómica de los músculos papilares debe ser considerada para la correcta interpretación de imágenes, implantación valvular y evaluación del desempeño en eventos isquémicos miocárdicos.

Descemet's membrane endothelial keratoplasty for primary graft failure after penetrating keratoplasty / Transplante endotelial de membrana de Descemet para falência primária após transplante penetrante

ABSTRACT Primary graft failure (PGF) is a known complication following penetrating keratoplasty (PKP). The usual approach to treat this complication is to repeat a penetrating keratoplasty. Here, we report a case of Descemet's membrane endothelial keratoplasty (DMEK) for the treatment of PGF after PKP. A patient that underwent PKP, developed PGF with persistent graft edema and very poor visual acuity despite aggressive steroid use and a proof anti-viral treatment. Three months after the initial surgery, a DMEK was performed under the PKP graft. There was progressive early corneal clearing and, by the end of the first month, the patient already had no corneal edema. Uncorrected visual acuity (UCVA) improved to 20/40 and best corrected visual acuity (BCVA) to 20/20. DMEK may be an alternative to a second PKP for the treatment of PGF. This technique is a less invasive option when compared to the standard PKP procedure.

RESUMO A falência primária do enxerto é uma complicação conhecida que pode ocorrer após o transplante penetrante de córnea. O tratamento usual dessa complicação é com um novo transplante penetrante. Apresentamos um caso em que foi usado o transplante endotelial de membrana de Descemet (DMEK - do inglês Descemet membrane endo-thelial keratoplasty) para o tratamento da falência primária após o transplante penetrante. Uma paciente submetida a transplante penetrante evoluiu com falência primária do enxerto a despeito do uso intenso de corticoide tópico e uma prova terapêutica de antivirais. Três meses após a cirurgia inicial, foi optado pela realização do transplante endotelial de membrana de Descemet sob o transplante penetrante. Houve um clareamento precoce e progressivo do enxerto com melhora importante da visão. Após um mês, a visão sem correção era de 20/40 melhorando para 20/20 com refração. O transplante endotelial de membrana de Descemet pode ser uma alternativa a um novo transplante penetrante como tratamento da falência primária.

Angle-closure glaucoma associated with vitreous prolapse after neodymium-doped yttrium-aluminum-garnet laser posterior capsulotomy

ABSTRACT Capsulotomy with neodymium-doped yttrium--aluminum-garnet (Nd:YAG) laser is an effective treatment for posterior capsule opacification following cataract surgery. A wide opening of the posterior capsule associated with the ruptured anterior hyaloid can cause anterior chamber vitreous prolapse. Two patients who developed angle-closure glaucoma associated with vitreous prolapse following Nd:YAG laser posterior capsulotomy were successfully treated with antiglaucoma medication and peripheral iridotomies. Patient identification for potential risk factors and a careful postoperative follow-up are essential to avoid these serious complications.

Toxoplasmosis outbreak in São Paulo, Brazil: Epidemiology and visual outcome

ABSTRACT Purpose: To describe a 2019 acute toxoplasmosis outbreak in the city of São Paulo, Brazil, and to evaluate the laboratory serological profile for toxoplasmosis for three consecutive years. The ophthalmological manifestations of the patients involved in the outbreak were also studied. Methods: A cross-sectional descriptive study of a toxoplasmosis outbreak in São Paulo, Brazil, between February and May 2019. Epidemiological data were described, as were the observed ocular manifestations. As part of this study the number of patients with positive IgM toxoplasmosis serology was obtained from a large laboratory network (DASA) for three consecutive years, including the year of the outbreak (2018, 2019, 2020). Results: Eighty-three individuals were identified in the outbreak and two clusters were studied. The clinical picture of at least 77% of the patients, the epidemiological analysis, and the short incubation period (5-8 days) suggested contamination by oocysts. Serological laboratory data analysis revealed an increase of positive toxoplasmosis IgM in 2019 of 73% compared to the previous year. Ophthalmological examination revealed that at least 4.8% of the patients developed toxoplasmic retinochoroiditis, none of whom had been treated during the acute systemic disease. Conclusion: Our findings indicate vegetable contamination as the possible source of this outbreak, a high prevalence of toxoplasmosis in São Paulo during the outbreak period, and a drop in the number of tests during the COVID-19 pandemic. Retinochoroiditis was observed in at least 4.8% of the cases. We confirm the need to implement effective means for the prevention, diagnosis, and treatment of the disease. This may involve raising awareness among the population of the importance of vegetable hygiene, and improved quality control of food and water.

Presumed acute posterior multifocal placoid pigmentary epitheliopathy associated with Bartonella infection / Epiteliopatia pigmentar placoide multifocal posterior aguda presumível associada com infecção por Bartonella

ABSTRACT To report a unique case of acute posterior multifocal placoid pigment epitheliopathy (APMPPE) in a patient with positive serology for Bartonella, presenting with ocular signs and symptoms not attributable to other diseases. A 27-year-old woman presented with decreased visual acuity in both eyes. Multimodal fundus image analysis was performed. A color fundus photograph of both eyes revealed peripapillary and macular yellow-white placoid lesions. The fundus autofluorescence of both eyes demonstrated hypo- and hyperautofluorescence of the macular lesions. Fluorescein angiography showed early-stage hypofluorescence and late staining of placoid lesions in both eyes. Spectral domain optical coherence tomography (SD-OCT) of both eyes revealed irregular elevations in the retinal pigment epithelium with the disruption of the ellipsoid zone on the topography of macular lesions. At 3 months after the treatment initiation for Bartonella infection, the placoid lesions became atrophic and hyperpigmented, and SD-OCT revealed loss of both the outer retinal layers and retinal pigment epithelium on the topography of macular lesions in both eyes.

RESUMO Caso de epiteliopatia pigmentada placoide multifocal posterior aguda presumida em paciente com sorologia positiva para Bartonella. Paciente feminina de 27 anos apresentou diminuição da acuidade visual em ambos os olhos. Análise multimodal de imagem foi realizada. A retinografia mostrou revelou lesões placoides amarelo-esbranquiçadas nas áreas peripapilar e macular de ambos os olhos. A autofluorescência demonstrou hipo e hiperautofluorescência em ambos os olhos, na mesma topografia das lesões detectadas na retinografia. A angiofluoresceínografia mostrou hipofluorescência na fase inicial do exame e hiperfluorescência tardia das lesões placoides em ambos os olhos. A tomografia de coerência óptica de domínio espectral de ambos os olhos revelou elevações irregulares do epitélio pigmentado da retina com descontinuação da zona elipsoide na área macular. Três meses após o início do tratamento para infecção por Bartonella, as lesões placoides tornaram-se atróficas e hiperpigmentadas, e a tomografia de coerência óptica revelou perda das camadas externas da retina e do epitélio pigmentado da retina na topografia das lesões maculares em ambos os olhos.

Hernioplastia inguinal con tejido autólogo. Técnica de Mohan Desarda

En las consultas de cirugía general se reciben, con frecuencia, pacientes portadores de hernias de la pared abdominal y, dentro de ellas, las hernias de la región inguinal. La hernia, como entidad, se menciona desde el año 1500 a. C. en el papiro Ebers. Su incidencia es alta, con una anatomía compleja, y en ocasiones se plantean porcentajes de recidivas frecuentes, por lo que hace de esta entidad un interesante tema con gran valor para los cirujanos en general. El objetivo de este trabajo es considerar que la técnica de reparación herniaria de Mohan Desarda cumple con los principios fundamentales de reparación de la hernia. En ella las complicaciones son mínimas debido a la utilización de una franja de tejido autólogo como refuerzo para el cierre del defecto, y el índice de recidiva es menor en comparación con el demostrado por otras.

In general surgery consultations, patients carrying hernias of the abdominal walls, and within them, hernias of the abdominal wall, are frequently received. The hernia, as an entity, has been mentioned since the year 1500 BC C. on the Ebers papyrus. Its incidence is high, with a complex anatomy, and sometimes percentages of frequent recurrency are stated, which makes this entity an interesting topic of great value for surgeons in general. The main objective of this work is to consider that Mohan Desarda's hernia repair technique complies with the main principles of hernia repair. In it, complications are minimal due to the use of a strip of autologous tissue as reinforcement for closing the defect, and the recurrence index is lower compared to that demonstrated by others.

Analysis of the Asterion Morphology in Relation to Its Clinical Significance / Análisis de la Morfología del Asterion en Relación con su Importancia Clínica

SUMMARY: The asterion presents a significant anthropological marking and meeting point between three sutures. It is a surface landmark for the transverse-sigmoid venous sinus complex and is also a surgical landmark for access to the posterior cranial fossa, giving it clinical importance. The aim of this research was to analyze the shape of the asterion and to set the measurement methods that will determine distance between the asterion and surrounding features. The study sample, as a part of the Osteological collection of the Department of Anatomy, Faculty of Medicine Novi Sad, consisted of 43 skulls. Morphometric analysis was related to the measurement of the defined parameters and descriptive analysis presented the classification of asterion in relation to the presence of sutural bones, as well as the determination of the position of the asterion according to the transverse-sigmoid venous complex. There was a statistically significant difference between male and female skulls for all the measured parameters. The results show that 34.88 % were type 1 (one or more sutural bones are present) and 65.12 % were type 2 asteria (no sutural bones are present). More frequent occurrence of asteria type 2 was seen on both, male and female skulls. The most frequent position of the asteria on both sides of the skull was in the transverse- sigmoid venous complex (76.92 % on the right side vs. 72.22 % on the left cranial side). Clinical significance of knowing the area of asterion is reflected in order to make the surgical, as well as diagnostic procedures, as successful as possible.

El asterion presenta una importante marca antropológica y punto de encuentro entre tres suturas. Es un punto de referencia de superficie para el complejo del seno venoso sigmoideo transverso y también es un punto de referencia quirúrgico para el acceso a la fosa craneal posterior, lo que le confiere importancia clínica. El objetivo de esta investigación fue analizar la forma del asterión y establecer los métodos de medición que determinarán la distancia entre el asterión y las características circundantes. La muestra del estudio, que forma parte de la colección osteológica del Departamento de Anatomía de la Facultad de Medicina de Novi Sad, estuvo compuesta por 43 cráneos. El análisis morfométrico se relacionó con la medición de los parámetros definidos y el análisis descriptivo presentó la clasificación del asterion en relación a la presencia de huesos suturales, así como la determinación de la posición del asterion según el complejo venoso transverso-sigmoideo. Hubo una diferencia estadísticamente significativa entre los cráneos masculinos y femeninos para todos los parámetros medidos. Los resultados muestran que el 34,88 % eran tipo 1 (hay uno o más huesos suturales presentes) y el 65,12 % eran asteria tipo 2 (no hay huesos suturales presentes). Se observó una aparición más frecuente de asteria tipo 2 en cráneos tanto masculinos como femeninos. La posición más frecuente de la asteria en ambos lados del cráneo fue en el complejo venoso sigmoideo transverso (76,92 % en el lado derecho vs. 72,22 % en el lado craneal izquierdo). La importancia clínica de conocer el área de asterion se refleja en que los procedimientos quirúrgicos y de diagnóstico tengan el mejor resultado posible.

Posterior capsular opacification and Nd:YAG capsulotomy rates in patients implanted with square-edged and non-square-edged intraocular lenses in manual small-incision cataract surgery: A randomized controlled study

Purpose: To study posterior capsular opacification (PCO) and neodymium?doped yttrium aluminum garnet (Nd:YAG) capsulotomy rates in patients implanted with square?edged and non?square?edged intraocular lenses (IOLs) in manual small?incision cataract surgery (MSICS). Setting: Tertiary eye care center. Design: Prospective, comparative, and randomized controlled study. Methods: This study included patients with senile cataracts scheduled for MSICS and IOL implantation. One eye of each patient was randomized to the implantation of square?edged (S group) or non?square?edged IOL (NSQ group). An independent observer analyzed PCO at 6, 12, 18, and 24 months under slit?lamp illumination. Results: A total of 104 eyes were included in this study. The mean age of the participants in the two groups was 63.2 (�2) years, and there were 65 (62.5%) men and 39 women (37.5%). The mean best?corrected visual acuity (BCVA) values at 6, 12, and 18 months were 0.157 (�10), 0.11 (�12), and 0.12 (�11), respectively, in the S group and 0.17 (�10), 0.17 (�12), and 0.20 (�17), respectively, in the NSQ group. At 12 (P = 0.03) and 18 months (P = 0.01) follow?up, the BCVA of the S group was significantly better than that of the NSQ group. Four eyes in the NSQ group and one eye in the S group required Nd:YAG. Conclusion: Evaluation of PCO and Nd:YAG capsulotomy rates showed that the 360� square of the posterior IOL edge plays a role in the prevention of PCO. Owing to the low cost of the material and the easy availability of IOLs manufactured from it, square?edged IOL has a definite role in the prevention of PCO in MSICS.

Posterior fossa choroidplexus papilloma in the pediatric population: case series and literature review / Papiloma de plexo coroide na fossa posterior na população pediátrica: série de casos e revisão da literatura

Abstract Choroid plexus papillomas (CPPs) are rare benign neoplasms which are particularly uncommon in the posterior fossa in children. We herein present a case series of five patients treated at a tertiary care hospital. A comprehensive literature review was also carried out. The patients treated at the tertiary care hospital were aged between 4 and 16 years. Gross total resection (GTR) was initially achieved in two patients. All patients showed clinical improvement. Moreover, 27 articles published between 1975 and 2021 were selected for the literature review, totaling 46 patients; with the 5 patients previously described, the total sample was composed of 51 cases, With a mean age was 8.2 years. The lesions were located either in the fourth ventricle (65.3%) or the cerebellopontine angle (34.7%). Hydrocephalus was present preoperatively in 66.7% of the patients, and a permanent shunt was required in 31.6% of the cases. The GTR procedure was feasible in 64.5%, and 93.8% showed clinical improvement. For CPPs, GTR is the gold standard treatment and should be attempted whenever feasible, especially because the role of the adjuvant treatment remains controversial. Neuromonitoring is a valuable tool to achieve maximal safe resection. Hydrocephalus is common and must be recognized and promptly treated. Most patients will need a permanent shunt. Though there is still controversy on its efficacy, endoscopic third ventriculostomy is a safe procedure, and was the authors' first choice to treat hydrocephalus.

Resumo Os papilomas do plexo coroide (PPCs) são neoplasias benignas raras e, na população pediátrica, são particularmente incomuns na fossa posterior. Apresentamos uma série de casos de cinco pacientes atendidos em um hospital terciário. Além disso, foi realizada uma ampla revisão da literatura. Os pacientes atendidos no hospital terciário tinham entre 4 e 16 anos. Ressecção macroscópica total (RMT) foi inicialmente realizada em dois pacientes. Todos os pacientes apresentaram melhora clínica. Além disso, 27 artigos publicados entre 1975 e 2021 foram selecionados para a revisão da literatura, totalizando 46 pacientes. Somados à série de casos atuais, encontramos 51 pacientes, com média de idade de 8,2 anos. As lesões localizavam-se no quarto ventrículo (65,3%) ou no ângulo pontocerebelar (34,7%). Hidrocefalia estava presente no pré-operatório em 66,7% dos pacientes, e derivação ventricular permanente foi necessária em 31,6% dos casos. A RMT foi possível em 64,5%, e 93,8% tiveram melhora clínica. Para os CPPs, a RMT é o tratamento padrão-ouro e deve ser tentado sempre que possível, especialmente porque ainda existem controvérsias quanto ao papel do tratamento adjuvante. A neuromonitorização é uma ferramenta importante para se atingir a máxima ressecção segura. A hidrocefalia é comumente vista nesses pacientes e deve ser identificada e tratada. A maioria dos pacientes irá precisar de uma derivação permanente. Apesar de persistirem controvérsias sobre sua eficácia, a terceiro-ventriculostomia endoscópica foi a primeira escolha para tratar a hidrocefalia na experiência dos autores e é uma opção segura.

Refractive outcomes of toric intra-ocular lens implantation in cases of high posterior corneal astigmatism

Purpose: To evaluate whether the toric intra?ocular lens (IOL) power calculation based on total corneal astigmatism (TCA) in eyes with high posterior corneal astigmatism (PCA) could result in a systematic over?correction or under?correction after operation. Methods: The present study included a mono?centric retrospective study design. The data were collected from 62 consecutive eyes during uncomplicated cataract surgery by a single surgeon with a measured PCA of 0.50 diopters (D) or higher. Toric IOL calculations were made using TCA measurements. The eyes were grouped as either “with?the?rule” (WTR) or “against?the?rule” (ATR) on the basis of the steep anterior corneal meridian. The post?operative refractive astigmatic prediction error was analyzed 1 month post?operatively using the vector analysis by the Alpins method and double?angle plots method. Results: The correction indexes were 1.14 ± 0.29 in the ATR eyes and 1.25 ± 0.18 for the WTR eyes, indicating a tendency toward over?correction. The mean over?correction was 0.22 ± 0.52D in the ATR group and 0.65 ± 0.60D in the WTR group. The magnitude of error (ME) values were significantly different from the ideal value of zero in both groups (ATR: P = 0.03; WTR: P = 0.00). No significant difference in mean absolute error (MAE) in predicted residual astigmatism was found between ATR and WTR groups (0.61 ± 0.42 D versus 0.64 ± 0.39 D; P = 0.54). The ATR group yielded better results, with 48% <0.50D prediction error in the main analysis. Conclusions: The results suggested that in cases of high PCA, the toric IOL calculation, which was performed using TCA, may cause a potential over?correction in the ATR and WTR eyes. For ATR eyes, over?correction led to slight disruption of post?operative visual quality because of the “with?the?rule” residual astigmatism after operation. Therefore, we suggested using TCA for toric IOL calculation in ATR eyes.

Assessing the validity of flap motility sign in predicting the extent of anterior capsular tears in phacoemulsification

Capsulorhexis is an integral step of cataract surgery, and continuous curvilinear capsulorhexis is crucial during phacoemulsification to prevent intraoperative complications. However, sometimes during phacoemulsification in complicated and hard cataract cases, rhexis extension may occur, resulting in posterior capsular rent, nucleus drop, cortex drop, and aphakia. It may not always be possible to continue with phacoemulsification in all cases. In this perspective, the authors describe a novel flap motility sign (FMS) to predict the extent of anterior capsular tear during phacoemulsification. A total of 21,678 patients underwent phacoemulsification for three years, from July 2016 to June 2019. One hundred and twenty-one patients had an anterior capsular tear. There were 102 cases (84.3%) with pre-equatorial tears and 19 cases (15.70%) with postequatorial tears. All pre-equatorial flaps were everted and fluttering, and all postequatorial flaps were inverted and nonfluttering. Posterior capsule rupture (PCR) was observed in all 19 cases of postequatorial flaps (100%). No PCR was observed in patients with fluttering and everted flaps (0%). In-the-bag and scleral-fixated intraocular lens implantations succeeded in pre-equatorial and postequatorial tears, respectively. There was no case of a nucleus drop. This study validates FMS as a predictor for identifying the extent of anterior capsular tears, thereby determining the endpoint of safe phacoemulsification and the site for intraocular lens implantation. Pre-equatorial tears allow for the continuation of safe phacoemulsification and in-the-bag intraocular implantation. Postequatorial tears necessitate timely conversion to small-incision cataract surgery or extracapsular cataract extraction.

Chop and tumble nucleotomy – A technique for safe nuclear emulsification in posterior polar cataract

A modified phaco chop technique for nuclear emulsification in posterior polar cataracts with nuclear sclerosis that avoids hydrodissection or nuclear rotation has been described. After performing a vertical chop maneuver to divide the nucleus, two pie-shaped nuclear fragments are removed from either side of the initial chop. The remaining nuclear fragments are then sequentially tumbled toward the center using the second instrument and emulsified while maintaining an intact epinuclear shell, which safeguards the fragile posterior capsule. The technique was successfully performed in 62 eyes of 54 patients with posterior polar cataract and grade II–IV nuclear sclerosis. The Chop and Tumble nucleotomy is a safe and effective technique for phacoemulsification in posterior polar cataracts with nuclear sclerosis, where hydrodissection and nuclear rotation are typically avoided

Morphological Study of Small Cardiac Vein, Right Marginal Vein, Posterior Vein of the Left Ventricle, Left Marginal Vein, Oblique Vein of Marshall, and Anterior Cardiac Veins in Human Hearts of Western Region of U.P – Clinical Implication

Introduction:Cardiac venous system is an important system for various cardiac interventional procedures such as cardiac catheterization. Various veins like right marginal vein, small cardiac vein (SCV), posterior vein of the left ventricle, left marginal vein, oblique vein of Marshall drain into coronary sinus. While anterior cardiac veins drain right ventricular wall directly into right atrium. Materials and Methods: An observational cross‑sectional study was conducted on thirty cadaveric hearts during a 2‑year period in Shri Ram Murti Smarak Institute of Medical Sciences, Bareilly, Anatomy Department. The length, diameter of SCV, left marginal vein, posterior vein of the left ventricle, right marginal vein, and oblique vein of Marshall were taken. Results: The study reveals the length of SCV as 28.12 ± 22.87 mm. The length of right marginal vein and posterior vein of the left ventricle is having a significant correlation with age. The length of oblique vein of Marshall is lower in males as compared to females. A number of ACVs were significantly related to weight of cadaver in males. Conclusions: The present study provides data of cardiac veins for various cardiac interventional procedures.

Posterior segment involvement in systemic lupus erythematosus – A series from South India

Purpose: To report the spectrum of posterior segment manifestations and visual outcomes in a large series of patients with systemic lupus erythematosus (SLE). Methods: Retrospective study at a tertiary referral eye center in south India between 2016 and 2022. Results: Charts of 109 patients diagnosed to have SLE were retrieved from our medical database. Only nine cases of SLE (8.25%) had posterior segment involvement. The male: female ratio was 1:8. The mean age was 28 years. Unilaterality was the most common presentation in eight cases (88.89%). Lupus nephritis was the most common systemic presentation in five cases (55.56%). Antiphospholipid antibodies (APLA) positivity was seen in two cases (22.22%). Ocular manifestations included microangiopathy (cotton wool spots) in one case, occlusive retinal vasculitis with cotton wool spots in four cases (five eyes), optic disc edema with combined venous and arterial occlusion (one case), central retinal vein occlusion with cotton wool spots and hemorrhages (one case), macular edema (four cases), posterior scleritis with optic disc edema and exudative retinal detachment in the posterior pole (one case), and tubercular choroidal granuloma (one case). Treatment included systemic steroids, hydroxychloroquine sulfate (HCQS), and immunosuppression in all cases, blood thinners in two cases, and laser photocoagulation in four cases. HCQS?related retinal toxicity was not seen in any of the 109 cases. Ocular manifestation was the initial presentation of SLE in one case. Visual outcome was poor in three cases. Conclusion: Presence of posterior segment findings in cases with SLE may suggest a severe systemic disease. Early detection and aggressive treatment result in better visual outcomes. Ophthalmologists could play a vital role in guiding systemic therapy.

Clinical profile and management with immunosuppressants and biologics in Behcet’s uveitis: A cohort of 25 patients from a tertiary eye care center in South India

Purpose: To report the clinical profile of Behcet’s disease and its management with immunosuppressants and biologics in a cohort of 25 patients from a tertiary eye care center in South India. Methods: This was a retrospective, observational study. Records of 45 eyes of 25 patients between January 2016 and December 2021 were retrieved from the hospital database. Complete ophthalmic evaluation and systemic examination by the rheumatologist with appropriate investigations had been done. Results were analyzed using Statistical Package for the Social Sciences (SPSS) software. Results: Males (19, 76%) were found to be more affected than females (6, 24%). Mean age of presentation was 27.68 ± 11.08 years. Twenty patients had bilateral involvement (80%), and unilateral involvement was seen in five patients (20%). Seven eyes of four patients (16%) had isolated anterior uveitis, out of which one patient had unilateral and three patients had bilateral involvement. Twenty?six eyes of 16 patients (64%) had posterior uveitis, out of which six patients had unilateral and 10 had bilateral involvement. Twelve eyes of seven patients (28%) had panuveitis, out of which two patients had unilateral and five had bilateral involvement. Hypopyon was seen in five eyes (11.1%) and posterior synechiae in seven eyes (15.55%). Posterior segment findings included vitritis (24.44%), vasculitis (17.78%), retinitis (17.78%), disc hyperemia (11.11%), and disc pallor (8.89%). Steroids alone were given in five patients (20%) and intravenous methylprednisolone (IVMP) was given in four patients (16%). Immunosuppressive agents along with steroids were given in 20 patients (80%), of which azathioprine alone was given in seven patients (28%), cyclosporin alone was given in two patients (8%), mycophenolate mofetil alone was given in three patients (12%), combination of azathioprine and cyclosporin was given in six patients (24%), and combination of methotrexate and mycophenolate mofetil was given in one patient (4%). Biologics were given in 10 patients (40%) – adalimumab in seven patients (28%) and infliximab in three patients (12%). Conclusion: Behcet’s disease is an uncommon uveitis in India. Addition of immunosuppressants and biologics to conventional steroid therapy gives better visual outcomes.

Impact of preoperative posterior segment evaluation on surgical intervention in camp patients: A retrospective analysis

Purpose: To retrospectively study impact of preoperative posterior segment evaluation on surgical intervention in camp patients recruited for cataract surgery in Gujarat India. Methods: Retrospective analysis of six months data collected from hospital electronic medical record (EMR) system of 9820 admitted patients recruited from screening camp for cataract surgery from 1/10/2019 to 31/3/2020 in Tertiary Eye Hospital in Gujarat, India, has been done. Comprehensive clinical evaluation, of both anterior and posterior segment which included detailed history; best corrected visual acuity (BCVA); intraocular pressure measurement with non?contact tonometer (NCT) and when required with Goldman applanation tonometer; slit lamp examination; and fundus examination with + 90 diopter lens as well as indirect ophthalmoscope as and when indicated. In case there was no view of retina, a B?scan ultrasound was done to rule out any posterior segment pathology. Immediate surgical intervention done was assessed and results analyzed in percentage. Results: Cataract surgery was advised for 8390 patients (85.43%). Surgical intervention for management of glaucoma was done for 68 patients (0.692%). Retina intervention was done for 86 patients. Posterior segment evaluation changed immediate surgical plane of management for 154 (1.57%) patients. Conclusion: Comprehensive clinical evaluation is economical and should be mandatory especially in community services as comorbid conditions like glaucoma, diabetic retinopathy, retinal vein occlusion, and other varied posterior segment diseases contribute significantly to visual disability in elderly age group. It is difficult to follow these patients later if manageable comorbidity is not informed about and if indicated dealt simultaneously for visual rehabilitation of patient.

Retrospective analysis of the role of anterior segment optical coherence tomography and outcomes of cataract surgery in posterior polar cataract

Purpose: To evaluate the visual and surgical outcomes of cataract surgery in patients with posterior polar cataract (PPC) and to evaluate the benefits of preoperative anterior segment optical coherence tomography (AS?OCT). Methods: This was a retrospective, single?center study. Case records of patients diagnosed with PPC who underwent cataract surgery either by phacoemulsification or manual small?incision cataract surgery (MSICS) from January to December 2019 were analyzed. Data collected include demographic details, preoperative best corrected visual acuity (BCVA), AS?OCT, type of cataract surgery, intraoperative and postoperative complications, and visual outcome at 1?month follow?up. Results: One hundred patients were included in the study. Preoperative posterior capsular defect was noted on AS?OCT in 14 patients (14%). Seventy?eight underwent phacoemulsification and 22 underwent MSICS. Intraoperatively, posterior capsular rupture (PCR) was seen in 13 patients (13%) and cortex drop was noted in one among them (1%). Out of 13 PCRs, 12 were found to have posterior capsular dehiscence preoperatively in AS?OCT. The sensitivity of AS?OCT for detecting posterior capsule dehiscence was 92.3% and specificity was 97.7%. The positive predictive value and negative predictive value were 85.7% and 98.8%, respectively. There was no significant difference in the incidence of PCR between phacoemulsification and MSICS (P = 0.475). The mean BCVA at 1 month was found to be better with phacoemulsification than MSICS (P = 0.004). Conclusion: Preoperative AS?OCT has excellent specificity and negative predictive value in identifying posterior capsular dehiscence. It thus helps to plan the surgery and counsel patients appropriately. Both phacoemulsification and MSICS provide good visual outcome with similar complication rates.

A Prospective Observational Study on Outcomes of Single Stage Posterior Decompression and Fixation for Dorsolumbar Spine Tuberculosis / Estudo observacional prospectivo sobre os desfechos da descompressão posterior e fixação em estágio único na tuberculose da coluna dorsolombar

Abstract Objective To study the results of only posterior decompression and instrumentation in dorsal and dorsolumbar spine tuberculosis. Methods The patients (n = 30) who were included in this study had dorsal or dorsolumbar spine tuberculosis, with or without neurological deficit, and with or without deformity. All 30 patients were managed by only posterior approach decompression and instrumentation. We studied cases for correction and maintenance of deformity at dorsal and dorsolumbar spine, functional outcome by the Oswestry disability index (ODI) and visual analogue scale (VAS) scores, as well as neurological outcome by the Frankel grade. Results In the current series, 30 patients were operated with single stage posterior decompression and instrumentation, and showed significant improvement in neurological status and functional outcomes, which were accessed by the ODI score, VAS score, and Frankel grade. Conclusion The posterior (extracavitary) approach provides optimum access to the lateral and anterior aspects of the spinal cord for good decompression. It facilitates early mobilization and avoids problems of prolonged recumbency, provides better functional outcome, and significantly better sagittal plane kyphosis correction.

Resumo Objetivo Estudar os desfechos da descompressão posterior isolada e instrumentação na tuberculose da coluna dorsal e dorsolombar. Métodos Os pacientes (n = 30) incluídos neste estudo apresentavam tuberculose na coluna dorsal ou dorsolombar, acompanhada ou não por déficit neurológico e/ou deformidade. Todos os 30 pacientes foram tratados apenas por descompressão posterior e instrumentação. Estudamos a correção e manutenção da deformidade na coluna dorsal e dorsolombar, o desfecho funcional segundo o índice de deficiência de Oswestry (ODI) e a escala visual analógica (EVA); o desfecho neurológico foi estudado de acordo com a classificação de Frankel. Resultados Na atual série, 30 pacientes foram submetidos à descompressão posterior e instrumentação em estágio único e apresentaram melhora significativa no estado neurológico e desfecho funcional segundo os scores de ODI, EVA e classificação de Frankel. Conclusão A abordagem posterior (extracavitária) permite o acesso ideal aos aspectos laterais e anteriores da medula espinhal para uma boa descompressão. Facilita a mobilização precoce, evita problemas associados ao decúbito prolongado, proporciona melhor desfecho funcional e corrige a cifose no plano sagital de maneira significativamente melhor.

A Rare Case of Posterior Ischemic Optic Neuropathy after Appendicectomy

Ischemic optic neuropathy is classified into anterior and posterior ischemic optic neuropathy depending upon the part of optic nerve involved. In anterior optic neuropathy, optic nerve head is involved and in posterior ischemic optic neuropathy(PION) retrobulbar portion is involved. There is sudden loss of vision in both the entities but there are optic disc changes in anterior optic neuropathy while in posterior ischemic optic neuropathy optic disc is normal initially. Etiologically, posterior ischemic optic neuropathy is divided into non arteritic non-surgical, arteritic and perioperative non arteritic posterior ischemic optic neuropathy.

MR Imaging in Eclampsia

Background : The aim of this study is to determine the distribution and nature of Cranial MRI findings in eclamptic patients, and to correlate them with clinical and laboratory data. Materials and Methods : This study was conducted in the Department of Obstetrics and Gynecology in Sri Ramachandra Institute of Higher Education and Research. A total number of 35 Eclamptic patients were included in this study and they were analyzed retrospectively. Laboratory parameters, Blood Pressure and Cranial MRI was performed for all and the same were analyzed statistically. Results : Out of 35 Eclamptic patients, MR Imaging was normal in 6 patients. Among the 29 patients with abnormal MRI, Cortical-subcortical Lesion, appeared iso/hypo-intense in T-1 weighted images and hyper intense in T-2 weighted images. In most of the patients, occipital lobe was involved followed by involvement of other lobes such as Parietal, Frontal, Temporal, Basal Ganglia and Cerebellum. When patients with and without positive MRI findings were compared regarding clinical features such as Headache, Blurred Vision, Nausea and Vomiting, Epigastric Pain, Loss of Consciousness, Reduced Urine Output there was no statistically significant difference between the two groups. Similarly, there was no statistical difference in mean arterial pressures between MRI positive and MRI negative patients (p=0.218) however, it was found that those with MR imaging positive features had a higher Blood Pressure than those with MRI negative findings. Among the laboratory parameters, in the patients with abnormal MRI findings Fibrinogen was found to be significantly low than those with normal MRI findings (p=0.0002).
