Introduction: Idiopathic macular hole is characterized as central loss of visual acuity. Bilateral presentation occurs with a frequency from 4.8 percent to 30 percent and spontaneous closure for diameters less than 250 um is 3.5 percent. Objective: To describe the forms of presentation and alternative treatments in patients with idiopathic macular hole. Case presentation: We present a case of a 66-year-old female patient with no medical history presenting with a simultaneous bilateral idiopathic macular hole. Optical coherence tomography examination of the right eye showed 190 um and of the left eye 210 um. In the left eye she underwent surgical intervention and in the right eye she presented spontaneous closure with favorable anatomical and functional evolution. Conclusions: Idiopathic macular holes can present bilaterally and therapeutic options and surgical management are some of the alternatives for their care(AU)

Bilateral giant full thickness macular holes: an infrequent manifestation of alport syndrome

Purpose: To report a case of Alport syndrome presenting with bilateral giant full-thickness macular holes, hypertensive chorioretinopathy, and exudative retinal detachment. Case Report: A 20 year-old man, a known case of Alport syndrome on hemodialysis, was referred to our clinic with bilateral vision loss initiated about 10 years prior to presentation, which exacerbated in the month prior to our visit. Bilateral large full-thickness macular holes, hypertensive chorioretinopathy, and exudative retinal detachment were detected in fundus examination. The patient had previous genetic counseling confirming the diagnosis of Alport syndrome. During follow-up, macular holes were covered with a thick epiretinal membrane and visual acuity decreased progressively in two weeks. Pars plana vitrectomy was performed in the right eye. Two weeks following surgery, the macular hole was closed and visual acuity improved significantly. Conclusion: Bilateral giant full-thickness macular holes are uncommon presentations of Alport syndrome. The retinal findings may be caused by an inefficient type IV collagen presenting in the Bruch's membrane and in the internal limiting membrane. Pars plana vitrectomy can be considered to repair macular holes in these patients.

Hipertensión ocular asociada al desprendimiento de la retina regmatógeno / Ocular hypertension associated to rhegmatogenous retinal detachment

Objetivo: Describir el comportamiento de la hipertensión ocular asociada al desprendimiento de la retina regmatógeno. Métodos: Se realizó un estudio observacional descriptivo de corte longitudinal retrospectivo de una serie de casos atendidos en la consulta de Vítreo-Retina del Instituto Cubano de Oftalmología "Ramón Pando Ferrer" en el período comprendido de mayo del año 2016 a diciembre de 2019. Se estudiaron 7 ojos de 7 pacientes. Se utilizaron las siguientes variables: edad, sexo, antecedentes patológicos oculares, tiempo de evolución de la disminución de la visión, tensión ocular, tipo de rotura retinal, cirugía de retina realizada y tratamiento antihipertensivo ocular. Resultados: Predominó el sexo masculino, con un promedio de edad de 27,2 años. La mayoría de los pacientes tuvieron rotura retinal en el cuadrante nasal superior y todos en extrema periferia. Todos los pacientes tuvieron la presión intraocular antes de la cirugía por encima de 30 mmHg. A todos se le indicó tratamiento hipotensor tópico y se les realizó cirugía convencional. Con diferentes fluctuaciones de la presión intraocular posterior a la cirugía, todos los pacientes normalizaron la tensión ocular y mantuvieron la retina aplicada. Conclusiones: El diagnóstico correcto de este síndrome puede ofrecer dificultad porque los signos de una condición pueden enmascarar los de otra. El reconocimiento de la entidad puede ser más fácil si el oftalmólogo tiene en mente que estas entidades pueden aparecer juntas. De esta forma, se hace un diagnóstico y un tratamiento certero que evite la discapacidad visual por esta causa(AU)

Objective: Describe the behavior of ocular hypertension associated to rhegmatogenous retinal detachment. Methods: An observational retrospective longitudinal descriptive study was conducted of 7 eyes of 7 patients attending the Vitreous-Retina Service at Ramón Pando Ferrer Cuban Institute of Ophthalmology from May 2016 to December 2019. The variables considered were age, sex, ocular pathological antecedents, time of evolution of vision reduction, ocular tension, type of retinal tear, retinal surgery performed and ocular hypertension treatment. Results: A predominance was found of the male sex, with a mean age of 27.2 years. Most of the patients had retinal tear in the upper nasal quadrant, and all in the extreme periphery. In all cases, intraocular pressure was above 30 mmHg before surgery. All patients were indicated topical hypotensive treatment and underwent conventional surgery. With different intraocular pressure fluctuations after surgery, all patients normalized their ocular tension and retained the retina applied. Conclusions: Correct diagnosis of this syndrome may be difficult to achieve, since the signs of one condition may mask those of another. Identification may be easier if the ophthalmologist bears in mind that these diseases may occur together. An accurate diagnosis may thus be made and an effective treatment indicated which will prevent visual disability due to this cause(AU)

Surgical results regarding the correction of macular hole with and without face-down posturing using 25% SF6 gas: a retrospective case series / Resultados cirúrgicos para correção de buraco macular com gás SF6 a 25% com e sem orientação postural: Série retrospectiva de casos

ABSTRACT Purpose: This study aims to compare the anatomical success rates of vitrectomy and SF6 gas tamponade for macular hole surgery with and without postoperative face-down posturing. Methods: This was an observational, longitudinal, and retrospective case series analysis. The study included 52 eyes from 52 patients who underwent pars plana vitrectomy with trypan blue-assisted internal limiting membrane peeling and 25% SF6 tamponade for stages 2, 3, and 4 macular holes. After surgery, all patients were provided with a postoperative postural regimen: 31 patients were instructed not to maintain face-down posturing, whereas 21 were instructed to maintain face-down posturing for 7 days. The primary outcome measure was the macular hole closure rate. Statistical analysis was performed using Epi Info 7.1. Results: A total of 47 (90.3%) patients achieved hole closure. The nonface-down posturing group and face-down posturing group obtained closure rates of 90.3% and 90.4%, respectively; these rates were not significantly different. Statistical analysis revealed that no significant differences existed in sex, age, hole duration, hole stage, preoperative visual acuity, or postoperative visual acuity between the two groups. Conclusion: Our results suggest that macular hole surgery with the use of short duration gas (SF6) is safe and effective and that maintaining a postural orientation of nonface-down posturing is also safe. However, these recommendations should be assessed further in a prospective and randomized study to comprehensively delineate the associated benefits and risks.

RESUMO Objetivos: Comparar as taxas de sucesso anatômico da vitrectomia e tamponamento de gás SF6 na cirurgia de buraco macular com e sem a postura pronada pós-operatória. Métodos: Foi realizado um estudo observacional, longitudinal e retrospectivo de séries de casos. O estudo incluiu 52 olhos de 52 pacientes submetidos à vitrectomia posterior via pars-plana com peeling de membrana limitante interna auxiliada por azul trypan e tamponamento com gás SF6 a 25% para os estágios 2, 3 e 4 dos buracos maculares. Após a cirurgia, todos os pacientes foram orientados a manter um regime postural pós-operatório: 31 pacientes foram orientados a não realizar posição pronada de cabeça, enquanto 21 foram orientados a manter uma pronada pós-operatória por 7 dias. O objetivo principal foi a análise da taxa de fechamento do buraco macular. A análise estatística foi realizada usando Epi-Info 7.1. Resultados: Um total de 47 (90,3%) pacientes obtiveram fechamento do buraco macular. O grupo de postura não pronada e o grupo de postura pronada obtiveram taxas de fechamento de 90,3%, e 90,4%, respectivamente; essas taxas não foram significativamente diferentes. A análise estatística revelou que não houve diferenças significativas relacionadas ao gênero, idade, duração do buraco macular, estágio do buraco macular, acuidade visual corrigida pré e pós-operatória entre os dois grupos. Conclusão: Nossos resultados sugerem que a cirurgia para buraco macular com o uso de gás de curta duração (SF6) é segura e eficaz e que a manutenção de uma orientação pós-operatória de não-pronada também é segura. No entanto, essas recomendações devem ser avaliadas em um estudo prospectivo e randomizado para delinear de forma abrangente os riscos e benefícios associados.

Flap invertido de membrana limitante interna en agujero macular grande / Inverted internal limiting membrane flap technique in large macular hole

RESUMEN El agujero macular es un desorden de la interface vitreorretinal definido como un defecto de espesor completo desde la membrana limitante interna hasta los segmentos externos de los fotorreceptores, que normalmente involucra a la fóvea. Con el desarrollo de la tomografía de coherencia óptica se han mejorado el diagnóstico, el tratamiento y el seguimiento de las enfermedades de la interface vitreorretinal, entre ellas el agujero macular. La vitrectomía pars plana es la técnica quirúrgica de elección para el agujero macular. Se presenta una paciente de 75 años, pseudofáquica, con mejor agudeza visual corregida en el ojo derecho de 0,1 Snellen. Se diagnostica agujero macular grande (810 µm) según su mínima apertura, con 8 meses de evolución. Se realizó vitrectomía pars plana, el levantamiento de la hialodes posterior, el flap invertido de membrana limitante interna, el uso de hexafluoruro de azufre en mezcla 20 por ciento y el posicionamiento de la paciente 24-72 horas. Se logró el cierre anatómico del agujero macular y la recuperación visual de 0,6 Snellen a los seis meses del tratamiento quirúrgico(AU)

ABSTRACT Macular hole is a disorder of the vitreous-retina interface defined as a full-thickness defect from the internal limiting membrane to the external segments of photoreceptors which typically involves the fovea. The development of optical coherence tomography has improved the diagnosis, treatment and follow-up of vitreous-retina interface diseases, among them macular hole. Pars plana vitrectomy is the surgical technique of choice for macular hole. A case is presented of a female 75-year-old pseudophakic patient with best corrected right eye visual acuity of 0.1 on the Snellen chart. Large macular hole is diagnosed (810 µm) according to its minimum opening, of 8 month's evolution. The following procedures were performed: pars plana vitrectomy, posterior hyalode lifting, inverted internal limiting membrane flap, use of sulfur hexafluoride in a 20% mixture, and positioning of the patient for 24-72 hours. Anatomical closure of the macular hole and a visual recovery of 0.6 Snellen were achieved six months after surgery(AU)

Resultados postquirúrgicos en pacientes con desprendimiento de retina regmatógeno asociado a agujero macular concomitante / Postsurgical results in patients with rhegmatogenous retinal detachment associated with concurrent macular hole

Introducción: el desprendimiento de retina regmatógeno (DRR) y agujero macular concomitante (AM) es una asociación poco frecuente, se reporta alrededor del 1-1,7%. Objetivo: presentar los resultados anatómicos y funcionales obtenidos en 11 casos intervenidos por DRR asociado a AM. Diseño del estudio: estudio observacional descriptivo retrospectivo. Método: estudio retrospectivo. Se registraron 11 pacientes con estas características entre 2010-2018. Se realizó vitrectomía con calibre 23 G, cerclaje escleral, remoción de membrana limitante interna (MLI), endofotocoagulación, lensectomía en los pacientes fáquicos y tamponaje con aceite de silicón o gas. Se evaluaron las siguientes variables: edad, sexo, agudeza visual (AV) al diagnóstico, tiempo de evolución del DRR, número de desgarros, grado de proliferación vitreoretiniana (PVR), si requirió retinectomía, tiempo de tamponaje con aceite de silicón, AV posterior a la extracción de aceite con colocación de lente intraocular y si se obtuvo el cierre del AM. El análisis estadístico descriptivo consistió en las variables cualitativas en frecuencias absolutas y relativas, mientras que en las cuantitativas medidas de tendencia central tipo promedio con rango mínimo y máximo. Resultados: los pacientes presentaban una edad promedio de 63 años (rango 53-74) con agudeza visual (AV) preoperatoria entre proyección luminosa y cuenta dedos. Diez pacientes presentaban mácula desprendida; el número de desgarros fueron de 1 a 2. El grado de PVR al diagnóstico: 2 grado B; 3 grado C2; 2 grado D1; 4 casos sin PVR. En 2 pacientes con PVR C3 y D1 se realizó retinectomía en 180°. En el 82% de los casos se logró la reaplicación de la retina en la primera cirugía, 100% en la segunda y en el 64% se constató el cierre completo del AM. La AV final fue entre 20/200 a 20/50, donde las mejores AV se asocian a casos con intervención precoz y sin PVR. Conclusión: Se encontró una tasa de reaplicación de la retina similar a O'Driscoll et al. donde alcanza el 78%, aunque solo 31% de su serie logra el cierre completo del AM utilizando gas SF6 como tamponaje sin pelaje de la MLI. En este estudio la tasa de cierre del AM es mayor alcanzando el 64% con pelaje de la MLI y una tasa de éxito anatómico con reaplicación de la retina en el 82% en la primera intervención.

Background: rhegmatogenous retinal detachment (RRD) and concomitant macular hole (MH) is a rare association, reported around 1-1,7%. Objective: to report anatomical and functional postoperative results in 11 patients with RD associated with MH. Study design: observational retrospective descriptive study. Method: this is a retrospective study. Eleven patients were registered with RRD and MH between 2010-2018. A 23G vitrectomy, scleral buckling, internal limiting membrane (ILM) peeling, laser photocoagulation, lensectomy in phakic patients and tamponade with silicone oil or gas were performed. The following variables were evaluated: age, sex, visual acuity (VA) at diagnosis, time of evolution of RRD, number of retinal tears, degree of vitreoretinal proliferation (VRP), if retinectomy is required, tamponade time with silicone oil, VA after extraction of silicon oil and scleral fixation of intraocular lens and if closure of the MH was obtained. The descriptive statistical analysis consisted of qualitative variables in absolute and relative frequencies; in the quantitative variables were applied measures of central tendency like average with minimum and maximum range. Results: the patients had an average age of 63 years (range 53-74) with preoperative visual acuity (VA) between luminous projection and counting fingers. Ten patients had detached macula; the number of retinal tears were 1 to 2. The degree VRP at diagnosis: 2 grade B; 3 grade C2; 2 grade D1; 4 cases without VRP. In 2 patients with VRP C3 and D1, a 180° retinectomy was performed. In 82% of the cases, the reapplication of the retina was achieved in the first surgery, 100% in the second and in 64% the complete closure of the MH was confi rmed. The final VA was from 20/200 to 20/50, where the best visual outcomes are associated with early intervention and without VPR. Conclusion: this study found a retinal reapplication rate similar to O'Driscoll et al. where it reaches 78%, although only 31% of this report achieves the complete closure of the MH using SF6 gas as tamponade without ILM peeling. In this study, the closure rate of the MH is greater reaching 64% with ILM peeling and an anatomical success rate with retinal reapplication in 82% in the first intervention.

Long-term Outcomes of Vitrectomy Used to Treat Myopic Traction Maculopathy

PURPOSE: We investigated the long-term outcomes of vitrectomy with internal limiting membrane (ILM) peeling as treatment for myopic traction maculopathy (MTM).METHODS: The medical records of patients who underwent vitrectomy to treat MTM were retrospectively evaluated. We excluded patients who exhibited macular holes (MHs) or retinal detachment at the time of primary surgery. The best-corrected visual acuity (BCVA) and central foveal thickness (CFT) were analyzed preoperatively, at 3, 6, 12, and 24 months after surgery, and at the final visit. Complications including retinal detachment or an MH were noted during follow-up.RESULTS: Twenty-three eyes of 22 patients were enrolled. At the time of primary surgery, the mean patient age was 64.4 ± 11.1 years and the baseline mean logMAR BCVA and CFT, 0.67 ± 0.50 and 431.8 ± 159.5 µm, respectively. The mean follow-up period was 53.7 ± 19.3 months. The mean logMAR BCVAs at 3, 6, 12, and 24 months postoperatively and at the final visit were 0.42 ± 0.39 (p = 0.001), 0.41 ± 0.38 (p = 0.001), 0.39 ± 0.40 (p < 0.001), 0.42 ± 0.43 (p < 0.001), and 0.51 ± 0.47 (p = 0.016), respectively, thus significantly better than the baseline value. The mean CFT at 3, 6, 12, and 24 months postoperatively and at the final visit were 244.6 ± 72.3, 210.5 ± 79.1, 209.6 ± 91.6, 219.8 ± 93.9, and 217.7 ± 81.3 µm, respectively, thus significantly less than baseline (all p < 0.001). MTM resolved in 18 eyes (78.3%) after primary surgery, without any complication, and remained stable to the final visit.CONCLUSIONS: Vitrectomy with ILM peeling afforded favorable long-term efficacy and safety in MTM patients.

New perspectives on macular hole surgery at three years of follow-up / Novas perspectivas em cirurgia de buraco macular com de 3 anos de seguimento

ABSTRACT Purpose: The aim of this study was to determine the functional and anatomical success rates as well as the safety of sutureless combined surgery involving vitreous base removal and internal limiting membrane peeling after Brilliant Blue G (0.5 mg/mL) staining for the management of idiopathic macular holes after three years. Methods: Forty-six eyes of 46 patients with an idiopathic macular hole were enrolled in this retrospective study. The inclusion criteria were macular holes with a minimum linear diameter below 1,500 mm, 0.05 or better decimal best-corrected visual acuity and duration of symptoms less than two years. The exclusion criteria included pregnancy, optic nerve atrophy, advanced glaucoma, and other chronic ocular diseases. The surgical procedure included internal limiting membrane peeling after Brilliant Blue G (0.5 mg/mL) staining, along with C3F8 tamponade and face-down positioning for three days postoperatively. Ophthalmologic examinations and optical coherence tomography were performed at 1 and 7 days and 1, 6, 12, 24, and 36 months postoperatively. If no anatomic closure of the macular holes occurred within the first month, the area of the internal limiting membrane peeling was enlarged in a second procedure. Multiple logistic regression and chi-squared tests were used for data analyses, and p-values of <0.05 were considered significant. Results: Out of 46 eyes with a preoperative idiopathic macular hole, anatomic closure was achieved in 42 (91.3%) after one procedure and in 45 (97.8%) after an additional surgery. The median postoperative best-corrected visual acuity improvement was 0.378 (range: 0.050-0.900) decimal. None of the patients experienced macular hole reopening, surgery-related complications, or ocular complications related to the dye. Conclusion: Combined surgery including vitreous base removal and internal limiting membrane peeling after staining with Brilliant Blue G (0.5 mg/mL) for the management of idiopathic macular holes resulted in adequate staining, best-corrected visual acuity improvement, and macular hole closure with no signs of ocular toxicity at the three-year follow-up examination.

RESUMO Objetivo: Determinar, após 3 anos de seguimento, as taxas de sucesso funcional e anatômico e a segurança da cirurgia combinada sem sutura, incluindo remoção da base vítrea e da membrana limitante interna após coloração com azul brilhante (0,5 mg/ml) para o manejo de buracos maculares idiopáticos. Métodos: Quarenta e seis olhos de 46 pacientes com buraco macular idiopático foram incluídos neste estudo retrospectivo. Os critérios de inclusão foram: buraco macular com diâmetro linear mínimo menor que 1500 micrômetros, acuidade visual com melhor correção de 0,05 decimal ou melhor e tempo de sintomas menor que 2 anos. Os critérios de exclusão foram gravidez, atrofia do nervo óptico, glaucoma avançado ou outra doença ocular crônica. A técnica cirúrgica incluiu a remoção da membrana limitante interna após coloração com Azul Brilhante 0,5 mg/ml, tamponamento com C3F8 posicionamento em prona ção durante 3 dias de pós-operatório. O seguimento foi realizado por exame oftalmológico e Tomografia de Coerência Óptica no 1 e 7 dias, 1, 6, 12, 24 e 36 meses de pós-operatório. Se o fechamento anatômico do buraco macular não fosse atingido na visita de um mês, realizava-se um segundo procedimento no qual a área do peeling da membrana limitante interna era ampliada. Para análise estatística, foram utilizados testes de regressão logística múltipla e Qui-quadrado. Valores de p menores que 0.05 foram considerados estatisticamente significativos. Resultados: Dos 46 olhos com buraco macular idiopático, 42 (91,3%) obtiveram fechamento do buraco macular após um procedimento cirúrgico e 45 (97,8%) após uma cirurgia adicional. A média de melhora da acuidade visual com melhor correção no pós-operatório foi de 0.378 (0.050-0.900) decimal. Não foram observados: reabertura do buraco macular, complicações relacionadas ao procedimento cirúrgico ou complicações relacionadas ao corante. Conclusão: A cirurgia combinada sem sutura que incluiu remoção da base vítrea e remoção membrana limitante interna após coloração com Azul Brilhante (0,5 mg/ml) para o tratamento de buracos maculares idiopáticos foi realizada com adequada capacidade de coloração, melhora da acuidade visual e fechamento do buraco macular sem sinais de toxicidade ocular no seguimento de 3 anos.

Clinical Features of Primary Rhegmatogenous Retinal Detachment According to Initial Intraocular Pressure

PURPOSE: To determine the correlations of intraocular pressure (IOP) with risk factors in rhegmatogenous retinal detachment (RRD) patients. METHODS: A total of 113 eyes in 113 consecutive patients with RRD were enrolled in this study. IOP was measured using applanation tonometry at the initial visit. Based on the difference in IOP between the affected and unaffected eyes, the subjects were divided into two groups: group 1 (IOP difference ≤ 2 mmHg) and group 2 (IOP difference > 2 mmHg). Correlations between the IOP and RRD morphology, visual acuity (VA), best-corrected VA (BCVA), retinal break size and location, range of retinal detachment, macular involvement, and proliferative vitreoretinopathy were analyzed. RESULTS: The IOP at the initial visit was 12.88 ± 3.2 mmHg in the affected eyes and 14.27 ± 2.5 mmHg in the unaffected eyes. The IOP difference between the affected and unaffected eyes was −1.40 ± 2.82 mmHg. The BCVA and range of retinal detachment showed statistically significant differences between groups 1 and 2. CONCLUSIONS: In patients with RRD, the IOP difference compared to the unaffected eye was correlated with the extent of area of retinal detachment and decreased BCVA.

Bilateral Rhegmatogenous Retinal Detachments after Systemic Pazopanib Treatment

PURPOSE: A case of bilateral rhegmatogenous retinal detachment is reported after pazopanib treatment of a patient with breast angiosarcoma. CASE SUMMARY: A 53-year-old female presented with bleeding in a right breast mass prior to an emergency room visit. She was diagnosed with metastatic breast angiosarcoma after a breast mass biopsy. She was treated with paclitaxel and radiation therapy. Systemic pazopanib treatment was added to treat lung metastasis. After 3 weeks, she felt sudden floaters in her right eye. In her fundus examination, there was vitreous hemorrhage, but no retinal detachment was noted. Five weeks later, she visited the clinic for a bilateral temporal visual field defect. A fundus examination showed bilateral retinal detachments with superonasal retinal tears. Both the patient and her family did not want surgery for her systemic condition because of her terminal cancer. CONCLUSIONS: Retinal detachment has been reported as a rare complication after systemic pazopanib treatment, but there has been no previous report in the Republic of Korea, therefore this is the first case of bilateral retinal detachments after systemic pazopanib treatment.

Long-term Clinical Outcome of Vitrectomy for the Treatment of Optic Disc Pit Maculopathy

PURPOSE: To evaluate the long-term outcomes of optic disc pit maculopathy after vitrectomy. METHODS: We evaluated retrospectively the medical records of eight patients with macular retinal detachment or retinoschisis who underwent vitrectomy due to optic disc pit maculopathy. The best-corrected visual acuity and optical coherence tomography findings were analyzed after surgery. RESULTS: Eight eyes of eight patients (two male and six female) were enrolled. The mean best-corrected visual acuity was 0.76 log MAR, the mean age was 42.8, and the mean follow-up period was 56 months (range: 8–120 months). At baseline, retinoschisis was observed in all eight eyes. Six eyes had serous retinal detachment of the macula. Vitrectomy for a complete posterior vitreous detachment was performed. Additional internal limiting membrane peeling and tamponade were performed in six and four eyes, respectively. After surgery, serous retinal detachment was gone in all eyes (100%) at a mean of 22.8 months (range: 18 days–60 months). Three of eight eyes (37.5%) showed the disappearance of retinoschisis at a mean of 6.8 months (range: 1.7–21 months), but the remaining patients still had retinoschisis at the final visit. Ocular complications were full-thickness macular hole and iatrogenic retinal detachment in each case. The final corrected visual acuity improved to 0.29 logMAR. CONCLUSIONS: Vitrectomy is an effective treatment for patients with optic disc pit maculopathy. It achieved anatomical and visual improvements over a long period of time. However, retinoschisis due to inner retinal fluid remained in many patients.

Clinical Characteristics of Intraocular Foreign Bodies According to Entrance Location: Corneal vs. Non-Corneal

PURPOSE: To investigate differences in the clinical features of post-traumatic intraocular foreign bodies (IOFBs) according to their entrance locations, specifically, those penetrating the cornea and those not penetrating the cornea. METHODS: A retrospective chart review was performed of patients with an IOFB from January 2011 to July 2016. The patients were divided into two groups: those in whom the IOFB entered through the cornea (“corneal entrance” group) and those in whom the IOFB did not penetrate the cornea (“non-corneal entrance” group), and compared. Damage to the anterior and posterior capsule, retinal tear, and retinal detachment were analyzed, and differences in surgical techniques including the IOFB extraction route and intraocular lens implantation were recorded. RESULTS: A total of 43 eyes (43 patients) were included, with 33 (76.7%) in the corneal entrance group and 10 (23.3%) in the non-corneal group. The posterior capsule was preserved in 24.2% (eight) of eyes in the corneal group and 80% (eight) of eyes in the non-corneal group. The corneal group had significantly more posterior capsule ruptures but dramatically fewer retinal tears (39.4%) than the non-corneal group (80% retinal tears). CONCLUSIONS: The location of IOFB entrance is a predictable factor of lens capsule and retinal injuries.

Surgical Repair of a Full-thickness Macular Hole in Retinitis Pigmentosa: a Case Report

PURPOSE: To report the long-term outcome after surgical repair of a full-thickness macular hole (FTMH) in a patient with retinitis pigmentosa (RP). CASE SUMMARY: A 55-year-old male who had been diagnosed with retinitis pigmentosa in both eyes 5 years earlier presented with decreased visual acuity in his left eye over the last 6 months. On examination, his Snellen best-corrected visual acuity (BCVA) was 1.0 in the right eye and 0.3 in the left eye. Slit-lamp examination of the anterior segment was remarkable only for posterior chamber intraocular lenses in each eye. Fundus examination demonstrated extensive bony spicule-like pigmentation in the mid-peripheral region in both eyes and a FTMH with approximately one-third disc diameter in the left eye. The optical coherence tomography (OCT) findings confirmed a FTMH with a surrounding cuff of intraretinal fluid and vitreomacular traction in the left eye. The patient underwent 23-gauge pars plana vitrectomy (PPV) with indocyanine green-assisted internal limiting membrane peeling and gas tamponade. One week postoperatively, an anatomically well-sealed macular hole was confirmed by OCT. At the 3-month postoperative follow-up, the BCVA improved to 0.63 and the hole remained closed until his last follow-up (postoperative 6 years). CONCLUSIONS: Although macular hole is a rare occurrence in RP patients, it should be considered as a cause of significant visual loss in patients with this disorder. Our case suggested that over the long-term, PPV may be tolerable in the management for FTMH in RP.

Utilizing a Previous Silicone Band Track in Recurred Retinal Detachment

PURPOSE: We report a case of utilizing a previous silicone band track in the reoperation of scleral encircling. CASE SUMMARY: An 8-year-old male presented with rhegmatogenous retinal detachment in the right eye. Five days after this diagnosis, he received scleral buckling surgery and cryopexy to seal the retinal tear. One month after surgery, a fundus examination showed subretinal fluid at the inferior site of the scleral buckle. He underwent scleral encircling surgery and a cryopexy procedure. The patient has had an uneventful postoperative course, and the retina has remained attached over a follow-up period of 9 months. However, exotropia and hypotropia developed in the right eye. Diagnosis of restrictive strabismus due to tissue adhesion around the silicone band was made. The encircling band was therefore removed and laser photocoagulation was performed 360° around the retina. Twenty-four hours after surgery, a fundus examination showed subretinal fluid. He received 360° scleral encircling surgery not using the 360° conjunctival peritomy. After confirming a previous encircling tract using #0-0 polydioxanone as a guide, #5-0 Nylon was tied to the end of the guide and inserted through the encircling tract with the end sutured with the silicone band. The silicone band was inserted into the encircling tract by pulling the #5-0 Nylon as a guide. Ophthalmoscopy revealed an attached retina with indentation of the scleral buckle at 360°. CONCLUSIONS: For reoperation in patients who previously underwent scleral encircling surgery, using the previous scleral encircling tract may be effective in cases with conjunctival and tissue adhesion.

Clinical Presentations of Focal Choroidal Excavation and Results of Long-term Follow-up

PURPOSE: To evaluate the clinical presentations of focal choroidal excavation and to report long-term outcomes of cases without retinal disorders at the initial presentation. METHODS: A retrospective review of medical records was performed for patients diagnosed with focal choroidal excavation. Concomitant retinal disorders at the initial presentation were identified. In cases without retinal disorders, the development of retinal disorders during follow-up was also evaluated. RESULTS: Forty-five eyes in 45 patients were examined in this study. Focal choroidal excavation was accompanied with retinal disorders in 16 eyes (35.6%). In the remaining 29 eyes, only focal choroidal excavation was noted without any accompanying retinal disorders. The accompanying retinal disorders included choroidal neovascularization (n = 8), central serous chorioretinopathy (n = 4), epiretinal membrane (n = 1), macular hole (n = 1), branch retinal vein occlusion (n = 1), and uveitis (n = 1). Of the 29 eyes without retinal disorders, 22 were followed up for a mean period of 33.5 ± 18.2 months. Consequently, choroidal neovascularization was found to have developed in one eye at 59 months, and subretinal fluid had developed in two eyes at 17 and 28 months, respectively. CONCLUSIONS: Focal choroidal excavation was accompanied by retinal disorders in 35.6% of the included patients. In patients without retinal disorders, the development of a retinal disorder was noted in some eyes, suggesting the need for long-term regular follow-up in patients diagnosed with focal choroidal excavation.

Long-term Outcomes of Macular Hole Retinal Detachment in Highly Myopic Eyes after Surgical Reattachment

PURPOSE: To evaluate visual acuity changes over 3 years following surgical reattachment of macular hole retinal detachment (MHRD) developed in high myopia.METHODS: A retrospective analysis was performed using the medical records of patients with highly myopic eyes who underwent pars plana vitrectomy with internal limiting membrane peeling or the internal limiting membrane flap technique for MHRD. Changes in best-corrected visual acuity (BCVA) were measured at baseline, 6 months, 1 year, 2 years, and 3 years.RESULTS: Of the 22 eyes analyzed, macular hole was closed in 13 and unclosed in nine. BCVA significantly improved from 1.61 ± 0.39 logarithm of the minimum angle of resolution (logMAR) at baseline to 1.17 ± 0.43 logMAR at 6 months and 1.33 ± 0.48 logMAR at 2 years after MHRD surgery. At 3 years, BCVA significantly decreased compared with that at 6 months, and visual improvement from baseline was not significant. BCVA and proportion of vision loss ≥0.3 logMAR were not different between the closed and unclosed macular hole groups.CONCLUSIONS: Visual improvement after surgical reattachment of MHRD in high myopia was not maintained, and favorable macular hole closure effects were not observed at 3-year follow-up.

Epiretinal Proliferation Associated with Lamellar Hole or Macular Hole: Origin and Surgical Prognosis

PURPOSE: To determine the origin of epiretinal proliferation (EP), a condition that is occasionally observed in lamellar hole and macular hole cases, and EP outcomes after vitrectomy. METHODS: This is a retrospective observational case review of 17 eyes with EP that underwent vitrectomy, EP dissection, and internal limiting membrane peeling between January 2013 and December 2016. Surgical specimens of EP tissue were successfully obtained from 5 cases and they were analyzed after immunohistochemical staining. Postoperative outcomes, including best-corrected visual acuity (BCVA) and macular configuration in spectral domain-optical coherence tomography, were reviewed. RESULTS: Mean BCVA improved from 0.54 ± 0.36 logarithms of the minimum angle of resolution preoperatively to 0.32 ± 0.38 logarithms of the minimum angle of resolution postoperatively (p = 0.002). BCVA improved in 13 eyes and remained unchanged in four eyes. No cases experienced vision decline after surgery. All 17 patients' lamellar hole or macular hole were successfully closed. Despite hole closure, ellipsoid zone defects were not corrected in 11 of the 17 patients. In immunohistochemical analyses, anti-glial fibrillary acidic protein and pan-keratin (AE1/AE3) were positive, but synaptophysin, anti-α-smooth muscle actin, and anti-CD68 were negative. CONCLUSIONS: The epiretinal proliferative membrane seems to originate from Müller cells, not from the vitreous. It is unclear whether retinal pigment epithelia also contribute to EP formation. Gentle handling and preservation of the epiretinal proliferative tissue is crucial for successful surgical outcomes.
