Hipertensión ocular secundaria a aceite de silicona / Ocular Hypertension Secondary to Silicone Oil

La silicona líquida es usada intravítrea cuando se requiere un taponamiento prolongado intraocular para mantener la retina aplicada. A pesar de sus ventajas, su uso se ha asociado a algunas complicaciones como catarata, queratopatía, hipertensión ocular, glaucoma entre otras. La hipertensión ocular secundaria por aceite de silicona aparece por varios mecanismos, la migración de partículas a la malla trabecular junto con el proceso inflamatorio que genera es un reto para los cirujanos, de ahí los diferentes criterios de tratamiento que existen para su completa resolución. A continuación, se presenta un paciente operado de desprendimiento de retina recidivado con hipertensión ocular secundario a aceite de silicona 9 meses después de su primera intervención. Llevó tratamiento con hipotensores oculares tópicos, orales y no resolvió por lo que se decide realizar ciclocrioterapia en dos cuadrantes. A pesar que este tratamiento no es el de elección en estos casos, podemos decir que en este paciente se logra controlar la presión intraocular luego de una sola sesión(AU)

Liquid silicone is used intravitreally when prolonged intraocular insulation is required to keep the retina applied. Despite its advantages, its use has been associated with some complications such as cataract, keratopathy, ocular hypertension, glaucoma, among others. Secondary ocular hypertension due to silicone oil appears by several mechanisms. The migration of particles to the trabecular meshwork, together with the inflammatory process it generates, represents a challenge for surgeons, hence the different treatment criteria that exist for its complete resolution. The following is a patient operated on for recurrent retinal detachment with ocular hypertension secondary to silicone oil 9 months after the first operation. He was treated with topical and oral ocular hypotensors and it did not resolve, so it was decided to perform cyclocriotherapy in two quadrants. Although this treatment is not the treatment of choice in these cases, we can say that in this patient intraocular pressure control was achieved after only one session(AU)

Glaucoma e óleo de silicone / Glaucoma and silicone oils

RESUMO O óleo de silicone é um importante tampão utilizado na retinopexia cirúrgica de casos graves de descolamento de retina. O aumento da pressão intraocular e o desenvolvimento de glaucoma secundário são frequentes complicações da sua utilização. A depender do período de aparecimento, diversos mecanismos justificam a ocorrência de tais complicações. Compreender os fatores de riscos e a patogênese do aumento da pressão intraocular associada a aplicação de óleo de silicone em cirurgia retiniana ajuda a orientar o tratamento adequado para cada paciente. O objetivo deste artigo é revisar a literatura sobre a patogenia, a incidência, os fatores de risco e o tratamento desta condição clínica.

ABSTRACT Silicone oil has been an important intraocular tamponade in retinopexy in cases of complicated retinal detachment surgery. The increase of intraocular pressure and development of secondary glaucoma are a known complication of its use. A variety of mechanisms have been proposed for the pathogenesis, depending on the onset. This article aims to review the literature about pathogenesis, the incidence and risk factors, as well as the treatment of this pathology.

Endophthalmitis Caused by Mixed Infections in Silicone Oil-filled Eye:One Case Report / 中国医学科学院学报

The incidence of endophthalmitis after vitrectomy is extremely low,especially lower in silicone oil-filled eyes.Silicone oil exerts a toxic effect on the cell membranes of microorganisms and leads to the lack of nutrients.It is thus believed to inhibit the growth of bacteria and fungi.Endophthalmitis induced by mixed bacteria in silicone oil-filled eye has been rarely reported.We reviewed the clinical manifestations,diagnosis,and treatment of a patient with endophthalmitis caused by mixed infection of

Siliconomas: Consideraciones terapéuticas. Algoritmo / Siliconomas: Therapeutic considerations. Algorithm

La inyección de aceites de silicona ha sido utilizada para modificar el contorno corporal en todo el mundo, especialmente en Japón desde 1940 y para el aumento mamario. Como cirujanos, nos encontramos cada vez más frecuentemente llamados a enfrentar los problemas generados por esta forma ilegal de aumento mamario: tumores de mama bilaterales, algunos dolorosos; masas duras que a menudo se confunden con un cáncer de mama avanzado, tumores axilares. La extrema dificultad para descartar un cáncer de mama a través del examen físico, mamografías, ecografías e incluso resonancia magnética (MRI) con gadolinio complican aún más el tratamiento en estas pacientes. Nuestra experiencia, de más de 20 años investigando esta patología, nos ha mostrado claramente que, para tratar a pacientes con esta enfermedad tan compleja, se requiere de un equipo terapéutico multidisciplinario. Este equipo debe tener una visión integral del paciente y comprometerse en el tratamiento de cada caso. Actuando de manera coordinada, abordando todas las diferentes sintomatologías de la enfermedad, ya sean locales o sistémicas, físicas o psicológicas. La inyección de siliconas y otros aceites tiene un impacto social muy desfavorable, ya que enferma e incapacita a un gran número de personas durante los años más productivos de su vida. Analizaremos los enfoques terapéuticos apropiados para cada forma de presentación de las enfermedades producidas por la inyección de siliconas en las mamas

The injection of silicone oils has been used to modify body contours around the world and especially in Japan, since 1940, most commonly to increase breast size. As surgeons, we find ourselves increasingly being called to deal with problems generated by this illegal form of breast augmentation­bilateral breast tumors, some painful, some not; hard masses that are often confused with advanced breast cancer; and axillary tumors­all caused by silicones. To this is added the extreme difficulty ruling out breast cancer through physical examinations, mammography, ultrasound, and even magnetic resonance imaging (MRI) with gadolinium. Our experience, over 20 years treating and investigating this pathology, has clearly shown us that, to treat these patients with such complex disease, a multidisciplinary therapeutic team is required. Moreover, that team must have a comprehensive vision and be committed to tailoring treatment to each patient individually. The team also must act in a coordinated manner, addressing all the different implications of disease, whether local or systemic, physical or psychological. The injection of silicones and other oils has had an unfavorable social impact, because it incapacitates a large number of people during the most productive years of their life. We will now present the appropriate therapeutic approaches for each form of mammary siliconoma presentation.

Efectividad de la facoemulsificación para el control de la presión intraocular en pacientes vitrectomizados con aceite de silicona / Effectiveness of phacoemulsification to control intraocular pressure in patients undergoing vitrectomy with silicone oil injection

RESUMEN Objetivo: Evaluar la efectividad de la cirugía de catarata para el control de la presión intraocular en pacientes vitrectomizados con aceite de silicona remitidos de la consulta de Retina al Servicio de Catarata del Instituto Cubano de Oftalmología Ramón Pando Ferrer, en el período comprendido de enero de 2016 a enero de 2017. Métodos: Se realizó un estudio descriptivo prospectivo de series de casos en 20 pacientes. El universo quedó conformado por todos los pacientes vitrectomizados, a quienes se les colocó aceite de silicona como sustituto del vítreo con diagnóstico de catarata e hipertensión ocular. Resultados: Los pacientes vitrectomizados con aceite de silicona, a quienes se les realizó cirugía de catarata, se caracterizaron por un predominio del sexo masculino y la edad menor de 60 años, asociado a enfermedad vitreorretiniana de base. La cirugía de catarata se relacionó con una importante disminución de la presión intraocular en el posoperatorio. Todos los pacientes alcanzaron un ángulo camerular abierto posterior a la cirugía, que favoreció la disminución del uso de tratamiento tópico. No fue necesaria la cirugía filtrante posterior a esta. Conclusiones: En los pacientes vitrectomizados, la cirugía de catarata muestra una mejoría sostenida de las presiones intraoculares hasta el sexto mes del posoperatorio(AU)

ABSTRACT Objective: Evaluate the effectiveness of cataract surgery to control intraocular pressure in patients undergoing vitrectomy with silicone injection referred by retina specialists to the Cataract Service of Ramón Pando Ferrer Cuban Institute of Ophthalmology from January 2016 to January 2017. Methods: A descriptive prospective case-series study was conducted of 20 patients. The universe was all the patients undergoing vitrectomy with administration of silicone oil as a vitreal substitute who were diagnosed with cataract and ocular hypertension. Results: Patients undergoing vitrectomy with silicone oil injection and cataract surgery were mostly male, mean age was under 60 years, and a relationship was found to underlying vitreoretinal disease. Cataract surgery was associated to a considerable reduction in intraocular pressure in the postoperative period. All patients achieved an open chamber angle after surgery, leading to a reduction in the use of topical medication. Eventual filtration surgery was not required. Conclusions: In patients undergoing vitrectomy, cataract surgery leads to sustained intraocular pressure improvement until the sixth month of the postoperative period(AU)

Comparison of topical and retrobulbar anesthesia in terms of pain experience during silicone oil extraction / Comparação da sensação de dor durante a extração de óleo de silicone sob anestesia tópica e retrobulbar

ABSTRACT Purpose: To compare the use of topical anesthesia and retrobulbar anesthesia during silicone oil removal with a mixed pars plana technique, through evaluating the pain experience of patients. Methods: We selected patients according to their behavior during previous vitreoretinal surgery and ophthalmologic examinations and divided them into two anesthesia groups: topical (n=36) and retrobulbar (n=33). We used a mixed technique for the passive removal of silicone oil in both groups. During each step of the surgery, the patients' pain experience and the surgeon's comfort were scored according to a pain scale. Results: The pain experienced during the application of the anesthesia was significantly greater in the retrobulbar group (p<0.001). The topical group experienced greater pain during trocar insertion (p<0.001). There was no significant difference between the groups regarding the overall pain experience or complications. Conclusions: The pain experience of the selected patients during silicone oil removal was comparable between the topical and the retrobulbar anesthesia. Topical anesthesia with the mixed pars plana technique is an effective and safe alternative option for silicone oil removal surgery.

RESUMO Objetivo: Comparar a sensação de dor de pacientes durante a remoção do óleo de silicone sob anestesia tópica e retrobulbar, usando uma técnica via pars plana combinada. Métodos: Os pacientes foram selecionados, de acordo com suas atitudes durante cirurgia vitreorretiniana prévia e exames oftalmológicos, e divididos em dois grupos: anestesia tópica e retrobulbar. Para a remoção passiva do óleo de silicone, utilizou-se uma técnica combinada em ambos os grupos. A sensação de dor dos pacientes e o conforto do cirurgião foram classificados através de uma escala de dor durante cada etapa da cirurgia. Resultados: Os grupos anestesia tópica e retrobulbar incluíram 36 e 33 pacientes, respectivamente. A sensação de dor durante a aplicação da anestesia foi significativamente maior no grupo retrobulbar (p<0,001). O grupo anestesia tópica sentiu mais dor durante a inserção do trocarte (p<0,001). Não houve diferença significativa entre os grupos em relação à sensação geral de dor e a complicações. Conclusões: A sensação de dor é comparável entre a anestesia tópica e a retrobulbar durante a remoção de óleo de silicone. A combinação de anestesia tópica e uma técnica via pars plana é uma opção alternativa eficaz e segura para a cirurgia de remoção de óleo de silicone.

Predictors and Outcomes of Vitrectomy and Silicone Oil Injection in Advanced Diabetic Retinopathy

PURPOSE: To evaluate visual and anatomical results and identify factors that influence vitrectomy and silicone oil (SO) injection outcomes in proliferative diabetic retinopathy (PDR). METHODS: This retrospective study included 236 eyes with PDR that were undergoing vitrectomy and SO injection with >3-month follow-up. The primary outcomes were final best-corrected visual acuity (BCVA) and retinal attachment rate. RESULTS: At the final visit (mean, 88 ± 58 weeks), complete, partial, and no retinal attachment were observed in 86.9%, 10.6%, and 2.5% of patients, respectively. A total of 155 eyes had experienced SO removal, while 81 had SO in place. The mean initial BCVA was 1.9 ± 0.7 logarithm of the minimum angle of resolution (logMAR) and significantly improved to 1.7 ± 0.8 logMAR (p = 0.001). Initial macular detachment (adjusted odds ratio [AOR], 0.25), development of iatrogenic break (AOR, 0.25), and use of heavy SO (AOR, 0.13) were independently associated with a lower risk of final retinal attachment, and SO removal was associated with a higher incidence (AOR, 7.55). Better baseline BCVA was associated with a higher risk of final BCVA ≥20 / 200. CONCLUSIONS: Despite an encouraging outcome based on anatomical data in advanced PDR treated with vitrectomy and SO, the functional prognosis was not satisfying for patients. Eyes with better vision at baseline had a more favorable prognosis, whereas eyes with initial macular detachment, intraoperative iatrogenic break, or heavy SO showed more unfavorable outcomes. In selected cases, extending the time of SO use did not worsen the prognosis.

Utilidad del sistema Scheimpflug por Pentacam para la cuantificación de la opacidad de la cápsula posterior en pacientes pseudofáquicos con aceite de silicona / Usefulness of Pentacam Scheimflug system for quantification of the posterior capsule opacity in pseudophakic patients with silicon oil-filled eyes

Objetivo: determinar si el sistema Scheimpflug por Pentacam tiene utilidad en la cuantificación objetiva de la opacidad de la cápsula posterior en los pacientes pseudofáquicos con aceite de silicona. Métodos: se realizó un estudio descriptivo, prospectivo y observacional en el Instituto Cubano de Oftalmología Ramón Pando Ferrer en el período comprendido entre abril del año 2012 y abril de 2014. Se evaluó, mediante sistema Scheimpflug del Pentacam para la cuantificación de la opacidad de cápsula posterior, a un grupo de 31 pacientes seudofáquicos sometidos a una vitrectomía previa con aceite de silicona y se compararon los resultados con los obtenidos en 26 pacientes operados solo de cirugía del cristalino con lente intraocular, para lo cual se utilizaron las variables edad, sexo, opacidad en grados por lámpara de hendidura y la intensidad media de píxeles en un área circular de 3 mm centrales seleccionada en los tomogramas, analizadas por el software Image J 1.42 q. Resultados: en los pacientes pseudofáquicos con aceite de silicona el sistema Scheimpflug no fue capaz de discernir entre los diferentes grados de opacidad de la cápsula posterior(p= 0,210) y no existió concordancia entre ambas mediciones (p= 0,120). Las mediciones realizadas en los pacientes pseudofáquicos con aceite de silicona con la lámpara de hendidura por dos observadores fueron similares (p= 0,042), al igual que existió buena correlación en las realizadas con el sistema Scheimpflug (r= 0,981). Cuando se compararon las mediciones realizadas con el sistema Scheimpflug en los dos grupos de pacientes se observó que las medias de intensidad en los grados 1 y 2 eran superiores a las halladas en los pacientes no vitrectomizados previamente, no así en los grados 3; solo en este último caso la diferencia fue significativa (p= 0,001). Conclusiones: el sistema Scheimpflug no es útil para cuantificar la opacidad de la cápsula posterior en los pacientes vitrectomizados previamente que aún tienen aceite de silicona(AU)

Objective: to determine whether the Pentacam Scheimpflug imaging system is useful for objective quantification of the posterior capsule opacity in pseudophakic patients with silicon oil-filled eyes. Methods: observational, prospective and descriptive study conducted in Ramon Pando Ferrer Cuban Institute of Ophthalmology in the period of April 2012 through April 2014. With the Pentacam Scheimpflug imaging system for the quantification of the posterior capsule opacity, 31 pseudophakic patients, who had undergone previous vitrectomy with silicon oil, were evaluated and their results were then compared with those of patients operated on through crystalline lens surgery and intraocular lens implantation (26 patients). To this end, the analyzed variables were age, sex, opacification degrees measured with slit lamp and average intensity in pixels in a 3mm round area selected from tomographs and analyzed by Image J 1.42 q software. Results: in pseudophakic patients with silicon oil-filled eyes, the Scheimpflug system could not differentiate the different levels of the posterior capsule opacity (p= 0.210) and there was no agreement between both measurements (p= 0.120). The measurements taken by two observers in pseudophakic patients using silicon oil and slit lamp were similar (p= 0.042) and good correlation in those taken with the Scheimpflug system (r= 0.981). When comparing the Scheimpflug system measurements taken in the two groups of patients, it was observed that the intensity means in grades 1 and 2 were higher than those found in non-vitrectomized patients, but in grade 3, the difference was significant (p= 0.001). Conclusions: Scheimpflug system is not useful to measure the posterior capsule opacity in previously vitrectomized patients who still have silicon oil-filled eyes(AU)

Comparison of 1000-centistoke versus 5000-centistoke silicone oil in complex retinal detachment surgery

Objective: To compare the efficacy and complications of using 1000-centistoke versus 5000-centistoke silicone oil for complex retinal detachment repair

Study Design: Case series

Place and Duration of Study: LRBT Tertiary Eye Hospital, Karachi, from January 2007 to June 2013

Methodology: Eighty-five eyes [85 patients] presenting with superior rhegmatogenous retinal detachments associated with PVR grades B and C [involving not more than 3 clock hours] were randomized to either 1000 centistokes [n=44] or 5000 centistokes [n=41] silicone oil group. All patients underwent 23-gauge pars plana vitrectomy surgery with silicone oil intraocular tamponade. Patient data was analysed at 18 months post-operatively. IBM SPSS 21 was used for data analysis

Results: There were 52 male and 33 female patients aged between 22 and 70 years [45.2 +/- 16.2]. After the first surgery, successful reattachment of the retina was achieved in 67 eyes [78.8%]; of which 35 eyes were in 1000-centistoke and 32 eyes in 5000-centistoke groups. Mean pre-operative Best Corrected Visual Acuity [BCVA] was 1.63 +/- 0.54 which was improved to a mean post-operative BCVA of 1.46 +/- 0.78 [1.42 +/- 0.74 in 1000-centistoke group; 1.49 +/- 0.78 in 5000 centistoke group]. The 1000-centistoke group had a significantly higher frequency of oil emulsification which necessitated early removal of silicone oil. There were 66 eyes [77%] with at least one complication [34 eyes in 1000-centistoke group; 32 eyes in 5000-centistoke group] including cataract, corneal abnormalities, raised IOP, hypotony, vitreous haemorrhage and retinal redetachment

Conclusion: Although visual and anatomical outcomes were comparable between the two groups, the 1000-centistoke silicone oil group developed early oil emulsification necessitating its early removal

Case of Atrophied Retina after Retinal Detachment Reoperation

PURPOSE: To report a case of visual deterioration and atrophied retina after pars plana vitrectomy (PPV) and silicone oil tamponade for the treatment of retinal detachment with previous encircling scleral buckling. CASE SUMMARY: A 29-year-old female visited for treatment of rhegmatogenous retinal detachment (RRD) in the right eye which was not completely resolved after encircling scleral buckling. Logarithm of minimal angle of resolution (log MAR) and best corrected visual acuity (BCVA) was 0.3. Retinal detachment from 3 to 8 O'clock without macular involvement was identified. Pars plana vitrectomy, endophotocoagulation and silicone oil tamponade were performed. During the operation, retinal dialysis and retinal break at the superonasal periphery were observed. The patient complained of central scotoma at 2 days postoperatively and hyper-reflection of the inner retina was identified on optical coherence tomography (OCT). At 2 weeks postoperatively, the OCT image revealed a thin retina and impending macular hole. After 2 months, the silicone oil was removed. Although the retina was well attached, the retina remained atrophied and the log MAR BCVA was 0.16. CONCLUSIONS: We report a rare case with deteriorated visual acuity after PPV and silicone oil tamponade for the retreatment of RRD in an atopic dermatitis patient.

Silicone Oil with Short-Term Prone Position in Macular Hole Retinal Detachment Surgery in High Myopia

PURPOSE: To evaluate the result of vitrectomy with internal limiting membrane peeling and silicone oil tamponade with short term face-down positioning in highly myopic patients with retinal detachment due to macular hole. METHODS: Eleven eyes of highly myopic patients with retinal detachment caused by macular hole were retrospectively reviewed. All patients underwent pars plana vitrectomy, internal limiting membrane peeling, and silicone oil tamponade with short term (1-3 days) face-down positioning. Silicone oil was removed between 6 and 12 months postoperatively. Outcomes included best-corrected visual acuity, retinal reattachment rate, macular hole closure, and complications. RESULTS: The mean age of patients was 63.3 +/- 8.3 years. During the silicone oil period, all 11 eyes (100%) had complete retinal attachment. After silicone oil removal, retinal detachment recurred in 2 eyes (18.2%). Macular hole closure was observed in 8 eyes (72.7%). The best corrected visual acuity (log MAR) improved from 1.99 +/- 0.94 before surgery to 1.33 +/- 0.62 at final visit. CONCLUSIONS: Pars plana vitrectomy, internal limiting membrane peeling and silicone oil tamponade with short term face-down positioning was effective in treating retinal detachment caused by macular hole in highly myopic eyes.

Outcomes of Relaxing Retinectomy in Patients with Proliferative Vitreoretinopathy

PURPOSE: To report the outcomes of relaxing retinectomy for retinal detachment in patients with proliferative vitreoretinopathy (PVR). METHODS: Sixty-four cases of relaxing retinectomy for PVR with a minimum follow-up of 6 months were retrospectively reviewed. The outcomes included achievement of complete retinal reattachment, PVR recurrence, the mean number of additional operations, visual acuity and incidence of postoperative complications. We analyzed the influence of intraoperative factors including lens status, retinectomy extent, additional scleral buckling, and tamponade agent on primary retinal reattachment. RESULTS: Complete retinal reattachment was achieved in 47 eyes (74.3%) without an additional surgery. PVR recurred in 19 eyes (29.7%) and an additional operation was performed in 17 eyes (26.6%). Fifty-seven (89.1%) eyes showed complete retinal reattachment and 40 eyes (62.5%) had visual acuity of 0.02 or more at the final follow-up visit. Hypotony was the major complication and developed in 10 eyes (15.6%). Eyes undergoing smaller ( or = 180degrees) retinectomy or gas tamponade (p = 0.043 and 0.013, respectively). CONCLUSIONS: Relaxing retinectomy is a useful technique for retinal detachment with PVR, but risk of recurrent proliferation or hypotony should be considered.

Two Cases of Recurrent Enterococcus Faecalis Endophthalmitis after Cataract Surgery

PURPOSE: To report 2 cases of recurrent Enterococcus faecalis (E. faecalis) endophthalmitis after uneventful phacoemulsification and posterior chamber intraocular lens (IOL) implantation. CASE SUMMARY: Case 1: A healthy, 75-year-old female presented with a sudden visual loss and ocular pain 2 days after phacoemulsification and IOL implantation. After successful treatment with intravitreal antibiotics injection, the infection was apparently cleared. At 1 month after the initial presentation, recurrent endophthalmitis occurred and was resolved with vitrectomy, silicon oil tamponade, and intravitreal antibiotics injection. Two months after vitrectomy, the silicone oil was removed and the patient's final visual acuity improved to 20/400 5 months later. Case 2: A healthy, 74-year-old female presented with a sudden visual loss 2 days after phacoemulsification and IOL implantation. After successful treatment with intravitreal antibiotics injection, the infection was apparently cleared. One month later, recurrent endophthalmitis occurred and was resolved with vitrectomy, posterior capsulotomy, and intravitreal antibiotics injection. Forty days later, the patient had a similar relapse. The infection resolved with IOL explantation, silicon oil tamponade, and repeated intravitreal antibiotics injections. E. faecalis was identified at the first and recurrent episode. Vancomycin and ceftazidime were used for each intravitreal administration. Silicone oil removal and IOL scleral fixation were performed and the patient's final visual acuity was 20/40 5 months later. CONCLUSIONS: Close monitoring for recurrences is recommended in endophthalmitis due to E. faecalis after phacoemulsification even after a successful initial treatment.

Surgical Outcomes of Transconjunctival 25-Gauge Plus Pars Plana Vitrectomy for Rhegmatogenous Retinal Detachment

PURPOSE: To evaluate anatomical and visual results of transconjunctival 25-gauge plus pars plana vitrectomy (PPV) in the management of primary rhegmatogenous retinal detachment (RRD). METHODS: A retrospective analysis of 46 eyes of 46 patients who underwent transconjunctival 25-gauge plus PPV for primary RRD repair between January 2013 and May 2013 with a minimum of 3-month follow-up was performed. Data collected for the study included patient demographics, lens status, preoperative visual acuity, macular status, and location and number of primary breaks. Main outcome measures were anatomical reattachment rate, postoperative visual acuity, operation time, and postoperative complications. RESULTS: The study included 30 men and 16 women. The mean age of the patients was 54.3 years. The locations of retinal breaks were 24 (52.2%) eyes in the superior half, 15 (32.6%) eyes in the inferior half, and 7 (15.2%) eyes on both sides. The macula-on RRD was present preoperatively in 21 (45.7%) of 46 eyes. Of the 33 (71.7%) phakic eyes, 18 (39.1%) underwent combined phacoemulsification, intraocular lens implantation, and PPV. Two different tamponades, C3F8 gas and silicone oil were used in this study. C3F8 gas was injected in the 33 (71.7%) eyes, and the remaining eyes were filled with silicone oil (1,300 centistokes for 11 eyes, 5,700 centistokes for 2 eyes). Mean operation time was 48.8 +/- 13.2 minutes. Retinal reattachment was achieved in 45 (97.8%) of 46 eyes at 3 months. Mean best-corrected visual acuity improved from 1.33 +/- 1.20 log MAR preoperatively to 0.68 +/- 0.94 log MAR postoperatively (p < 0.001). Postoperative complications included transient intraocular pressure elevation in 6 (13.1%) eyes and posterior capsular opacity in 3 (6.5%) eyes. CONCLUSIONS: It seems that transconjunctival 25-gauge plus PPV can be a safe and effective option for surgical management of RRD.

Characteristics of Women Who Have Had Cosmetic Breast Implants That Could Be Associated with Increased Suicide Risk: A Systematic Review, Proposing a Suicide Prevention Model

Literature indicates an increased risk of suicide among women who have had cosmetic breast implants. An explanatory model for this association has not been established. Some studies conclude that women with cosmetic breast implants demonstrate some characteristics that are associated with increased suicide risk while others support that the breast augmentation protects from suicide. A systematic review including data collection from January 1961 up to February 2014 was conducted. The results were incorporated to pre-existing suicide risk models of the general population. A modified suicide risk model was created for the female cosmetic augmentation mammaplasty candidate. A 2-3 times increased suicide risk among women that undergo cosmetic breast augmentation has been identified. Breast augmentation patients show some characteristics that are associated with increased suicide risk. The majority of women reported high postoperative satisfaction. Recent research indicates that the Autoimmune syndrome induced by adjuvants and fibromyalgia syndrome are associated with silicone implantation. A thorough surgical, medical and psycho-social (psychiatric, family, reproductive, and occupational) history should be included in the preoperative assessment of women seeking to undergo cosmetic breast augmentation. Breast augmentation surgery can stimulate a systematic stress response and increase the risk of suicide. Each risk factor of suicide has poor predictive value when considered independently and can result in prediction errors. A clinical management model has been proposed considering the overlapping risk factors of women that undergo cosmetic breast augmentation with suicide.

Surgical Treatment of Paraffinomas in Patients with Leprosy / 대한피부과학회지

BACKGROUND: Ulnar nerve palsy leads to thumb-web depression, hypothenar flattening, and inter-digital depression in patients with leprosy. To camouflage these deformities, patients used to inject paraffin or silicone oil into the areas of muscle atrophy associated with thumb-web depression and hypothenar flattening. After several years and decades, paraffinomas eventually resulted in extensive inflammatory fibrosis and recalcitrant recurrent ulcers at the injection sites. OBJECTIVE: The aim of this study is to compare the results of different surgical treatments for paraffinomas in patients with leprosy, and to find out the most effective treatment method that has a low recurrence rate. METHODS: Between January 2000 and December 2012, 47 patients with paraffinomas who had visited the Korean Hansen Welfare Association Hospital were enrolled to participate in the study. The number of paraffinomas was 56, and the mean age of the patients was 73 years. A retrospective evaluation of the cosmetic results and recurrence rate was performed. RESULTS: Of the 56 surgically treated paraffinomas, 30 lesions were treated using primary closure, 20 lesions were treated with skin graft, and 6 lesions were treated with skin flap. The cosmetic outcomes, which were assessed using a four-point grading scale, were excellent in 10.7% (6/56), good in 25% (14/56), fair in 38% (21/56), and poor in 28% (15/56) of the patients. There were no significant differences among the three surgical procedures with respect to the cosmetic results. The recurrence rate was 33% (10/31) in the primary closure group, 50% (10/20) in the skin graft group, and 17% (1/6) in the skin flap group. There were no significant differences in the recurrence rate among the three surgical procedures. CONCLUSION: The extensive and aggressive curettage of lesions is very important to reduce recurrence rate. When the older age of the patients is considered in conjunction with the simplicity of the operation and the total operation time, primary closure is considered the treatment of choice both cosmetically and practically.

Massive Spontaneous Suprachoroidal Hemorrhage in a Patient with Heavy Alcohol Consumption

PURPOSE: To report a case of massive spontaneous suprachoroidal hemorrhage in a middle-aged female with heavy alcohol consumption. CASE SUMMARY: A 48-year-old female with a history of heavy alcohol consumption developed a massive spontaneous suprachoroidal hemorrhage in the right eye. Fundus examination and B-scan ultrasonography of the right eye revealed a hemorrhagic choroidal detachment with kissing choroidal sign. On systemic evaluation, she was diagnosed with alcohol-induced hepatitis, diabetes, and diabetic nephropathy. We performed trans-scleral drainage of the suprachoroidal hemorrhage, trans pars plana vitrectomy and silicone oil injection in her right eye. CONCLUSIONS: To our knowledge, this is the first case report of massive spontaneous suprachoroidal hemorrhage in a patient with heavy alcohol intake.
