Manejo del desprendimiento de retina regmatógeno / Management of rhegmatogenous retinal detachment

1. INTRODUCCIÓN El desprendimiento de retina es un problema visual grave que puede ocurrir a cualquier edad, aunque suele darse en individuos de edad media o en personas de la tercera edad. La incidencia es relativamente baja considerando que las estima-ciones varían según zonas geográficas; y, se han reportado datos de entre 6,3 y 17,9 por 100 000 habitantes. Otras características im-portantes a considerar son la degeneración en encaje de 45,75% y la miopía de 47,28% que influyen en la presentación del desprendi-miento de retina. Al mismo tiempo que la edad, los cambios vítreos retinianos y la presencia de pseudofaquia1,2. Además, de los factores oculares relacionados también influyen, el seguimiento inadecuado de los factores de riesgo y el difícil acceso a médicos especialistas que se traduce en retraso en el diagnóstico certero y tratamiento tardío que implica deterioro del pronóstico visual cuando el área macular está incluida en el área desprendida con pobres resultados en adultos jóvenes y en edad productiva.El tratamiento evitará el deterioro o pérdida irreversible de la visión. El pronóstico con tratamiento quirúrgico es bueno si el des-prendimiento no incluye a la mácula.

1. INTRODUCTIONRetinal Detachment is a serious visual problem that can occur at any age, although it usually occurs in middle-aged or elderly in-dividuals. The incidence is relatively low considering that estimates vary ac-cording to geographical areas; and, data have been reported be-tween 6,3 and 17,9 per 100 000 inhabitants. Other important cha-racteristics to consider are socket degeneration of 45,75% and myopia of 47,28% that influence the presentation of retinal deta-chment, as well as age, vitreoretinal changes and the presence of pseudophakia1,2.In addition to the related ocular factors, inadequate follow-up of risk factors and difficult access to medical specialists also play a role, resulting in delayed accurate diagnosis and late treatment that implies deterioration of the visual prognosis when the macular area is included in the detached area with poor results in young adults and those of productive age.Treatment will prevent irreversible deterioration or loss of vision. The prognosis with surgical treatment is good if the detachment does not include the macula.

Pars plana vitrectomy and visual stimulation for treatment of vitreomacular traction secondary to toxoplasmosis retinochoroiditis in a 5-year-old child / Vitrectomia via pars plana e estimulação visual para tratamento da tração vitreomacular secundária à retinocoroidite por toxoplasmose em criança de 5 anos

ABSTRACT Objective: A unusual case of ocular toxoplasmosis with significant vitreomacular traction is reported. The patient improved significantly following pars plana vitrectomy combined with visual stimulation and occlusion therapy. Methods: The case of a 5-year-old girl with significant unilateral vision loss associated with vitreous condensation and macular traction is described. Results: Pars plana vitrectomy was carried out for vitreomacular traction release. This was followed by visual stimulation and occlusion therapy. Significant improvement was observed. Conclusion: Despite structural damage, the combination of properly indicated surgery and amblyopia management strategies allowed the achievement of maximum vision goals in this case, suggesting structural damage may be associated with functional amblyopia.

RESUMO Objetivo: Relata-se um caso de apresentação atípica de toxoplasmose ocular, com importante tração vitreomacular. A paciente apresentou melhora significativa após vitrectomia via pars plana, com estimulação visual e oclusão. Métodos: Descreve-se o caso de uma menina de 5 anos, com importante perda de visão unilateral associada à condensação vítrea e à tração macular. Resultados: Foi realizada vitrectomia via pars plana para alívio da tração vitreomacular, seguida de estimulação visual e oclusão. Foi observada melhora significativa. Conclusão: Apesar dos danos estruturais, a combinação de cirurgia bem indicada com estratégias de tratamento da ambliopia permitiu alcançar o máximo do potencial visual nesta paciente, sugerindo que os danos estruturais podem estar associados à ambliopia funcional.

Alternative technique for insertion of Eva Dorc® infusion cannula in vitreoretinal surgeries / Técnica alternativa de inserção da canula de infusão do Eva Dorc® em cirurgias vitreorretinianas

Abstract This paper provides a fast and inexpensive technique to prevent slippage of the infusion cannula from the EVA DORC® 27-gauge system. After the usual retrobulbar anesthesia, antisepsis and asepsis, a 2% hydroxypropyl methylcellulose drop is placed around the infusion cannula in the trocar to hold it in position. This technique prevents the slippage of the infusion cannula and both the surgical time and creation of the first sclerotomy in the eye can be shortened slightly.

Resumo Este artigo fornece uma técnica rápida e barata para evitar o deslizamento da cânula de infusão do sistema EVA DORC® 27-gauge. Após a habitual anestesia retrobulbar, antissepsia e assepsia, uma gota de 2% de hidroxipropilmetilcelulose é colocada ao redor da cânula de infusão no trocater para mantê-la em posição. Essa técnica evita o deslizamento da cânula de infusão e o tempo cirúrgico e da criação da primeira esclerotomia no olho podem ser ligeiramente reduzidos.

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.

Complications caused by perfluorocarbon liquid used in pars plana vitrectomy / 고신대학교의과대학학술지

OBJECTIVES: To assess the inadvertent intraocular retention of perfluorocarbon liquid (PFCL) after vitreoretinal surgery and their complications. METHODS: We retrospectively reviewed the medical records of 108 patients who underwent vitreoretinal surgeries using intraoperative PFCL (perfluoro-n-octane (C8F18), 0.69 centistoke at 25degrees C, PERFLUORN(R), Alcon, USA) and the removal of PFCL through fluid-air exchange. The analysis was focused on the occurrence of intraocular retained PFCL, diagnoses,surgicalprocedures,andcomplications. RESULTS: Retinal detachment (51 cases, 47%) was the most common surgery which used PFCL intraoperatively. Other causes were vitreous hemorrhage (24 cases, 22%), posteriorly dislocated lens (22 cases, 21%), and trauma (11 cases, 10%). Intraocular PFCL was found in a total of 9 (8.3%) eyes. PFCL bubbles remained in anterior chamber and vitreous cavity were observed in 4 cases and subretinal retained PFCL was observed in 5 cases. Three of 5 cases of subretinal PFCL exhibited in subfoveal space. Among the three subfoveal cases, macular hole developed after PFCL removal in 1 case, epiretinal membrane in the area where had been PFCL bubble. However, we observed no complications in 1 case of subfoveal PFCL that was removed by surgery. PFCL in anterior chamber and vitreous cavity were in 4 cases. CONCLUSIONS: The presence of subfoveal PFCL might affect visual and anatomic outcomes. However, subfoveal PFCL may induce visual complications, and therefore requires special attention.

The effect of dexmedetomidine sedation on patient and surgeon satisfaction during retinal surgery under sub-tenon's anesthesia: a randomized controlled trial / 대한마취과학회지

BACKGROUND: The purpose of this study was to evaluate the effect of intraoperative dexmedetomidine sedation on patient's and surgeon's satisfaction during retinal surgery under sub-tenon's anesthesia. METHODS: Forty-four patients scheduled for elective retinal surgery under sub-tenon's anesthesia were enrolled in this randomized controlled trial. The patients were divided into Dexmedetomidine (n = 22) and Control (n = 22) groups. Intravenous dexmedetomidine or 0.9% saline via infusion pump were administered continuously to the dexmedetomidine or control group, respectively. Ramsay sedation scale with a target level of 3-4 was used to assess adequacy of sedation. Perioperative pain, hemodynamic and respiratory data were collected, while satisfaction from patients and surgeon were assessed post-surgery using a 5-point satisfaction scale. RESULTS: Patient and surgeon satisfaction was higher in the dexmedetomidine group (P < 0.001, P = 0.002, respectively). The pain associated with sub-tenon's anesthesia and peripheral vitrectomy was lesser in the dexmedetomidine group than in the control group (P = 0.020). There was significant reduction of heart rate in the dexmedetomidine group (P = 0.001), but only one patient needed treatment with atropine. There was no respiratory effect on both groups. CONCLUSIONS: Dexmedetomidine sedation during retinal surgery improved satisfaction from both patient and surgeon without respiratory complication. It is a safe and preferable choice of sedation for retinal surgery.

Predictive factors for anterior chamber fibrin formation after vitreoretinal surgery / Fatores preditivos para formação de fibrina na câmara anterior após cirurgia vitreorretiniana

Purpose: The aim of this study was to investigate possible predictive factors related to anterior chamber fibrin formation after vitreoretinal surgery in a large series of patients. Methods: The data of 185 eyes of 185 patients submitted to vitreoretinal surgery was reviewed. The following variables were evaluated: the postoperatively presence of fibrin, age, diabetes mellitus, the vitrectomy system gauge (20, 23 or 25 gauge), the type of vitreous substitute, the influence of prior surgical procedures and the combination with cataract extraction. To evaluate predictive factors for anterior chamber fibrin formation, univariate analysis was performed. A multivariate stepwise logistic regression model was adjusted to investigate factors associated with fibrin formation (p<0.05). Results: Fibrinoid anterior chamber reaction was found in 12 (6.4%) patients. For multivariate logistic regression analysis, balanced salt solution (BSS), the chance of fibrin occurrence was 5 times greater (odds ratio 4.83, CI 95% 1.302 - 17.892; p=0.019), while combination with phacoemulsification increased the chance of fibrin formation by 20 times (odds ratio 20, CI 95% 2.480 - 161.347; p=0.005). No significant difference was found regarding other variables. Conclusion: Anterior chamber fibrin formation is an unwanted complication after vitreoretinal surgery. Factors such as combined performance of phacoemulsification and the use of balanced salt solution as a vitreous substitute may predispose the occurrence of this complication. .

Objetivo: Avaliar os possíveis fatores relacionados à formação de fibrina na câmara anterior após cirurgia vitreorretiniana em uma grande série de casos. Métodos: Foi realizado um estudo retrospectivo, observacional, caso-controle, onde os dados de 185 olhos de 185 pacientes submetidos à cirurgia vitreorretiniana foram avaliados. Os seguintes dados foram analisados: presença ou não de fibrina na câmara anterior na primeira semana de pós-operatório, idade, presença ou não de diabetes mellitus, calibre do sistema de vitrectomia utilizado (20,23 ou 25 gauge), substituto vítreo, a influência de cirurgias oftalmológicas prévias e a realização de cirurgia de catarata combinada. Para avaliação dos fatores preditivos para formação de fibrina, a análise univariada foi realizada. O modelo de regressão logística multivariada foi utilizado para investigar os fatores associados com a formação de fibrina (p<0,05). Resultados: A presença de fibrina na câmara anterior foi encontrada em 12 (6,4%) pacientes. Pela análise de regressão logística multivariada, o uso de solução salina balanceada (BSS) como substituto vítreo, a chance da presença de fibrina foi 5 vezes maior (odds ratio 4,83, IC 95% 1,302 - 17,892; p=0,019), enquanto que a realização de cirurgia facoemulsificação combinada aumentou a chance de formação de fibrina 20 vezes (odds ratio 20, IC 95% 2,480 - 161,347; p=0,005). Nenhuma diferença estatisticamente significativa foi encontrada para as outras variáveis. Conclusão: A formação de fibrina na câmara é uma complicação indesejada após cirurgia vitreorretiniana. Fatores como realização de cirurgia de facoemulsificação combinada e ...

Risk Factors for Development of Posterior Capsule Opacification after Cataract Surgery or Combined Vitreoretinal Surgery

PURPOSE: To evaluate the risk factors for the development of posterior capsule opacification (PCO) after cataract surgery or combined cataract and vitreoretinal surgery. METHODS: In the present study all surgical procedures were performed by the same surgeon. We retrospectively reviewed 272 consecutive eyes that received cataract surgery or combined cataract and vitreoretinal surgery. The risk factors including gender, age, diabetes, continuous curvilinear capsulorhexis (CCC) size, intraocular lens shape, intraoperative intravitreal bevacizumab, gas, and silicone oil injections were evaluated using multiple logistic regression analysis. RESULTS: PCO developed in 55 (20.2%) out of 272 eyes. The mean age was 63.3 +/- 12.1 years (range 23-85 years) and mean follow-up period was 17.3 +/- 3 months. A correlation existed between the development of the PCO and age (p 0.05). CONCLUSIONS: The risk factors associated with PCO included young age, large CCC size, combined cataract and vitreoretinal surgery, intraoperative intravitreal gas and silicone oil injections.

Evaluación y conducta recomendada en presencia de precursores vítreorretinianos del desprendimiento de retina / Evaluation and recommended behavior in presence of vitreous retinal precursors of the retinal detachment

Los cambios y las variaciones anatómicas vítreorretinianas predisponen al desprendimiento de retina regmatógeno, por lo que su conocimiento es de vital importancia para el tratamiento adecuado de los pacientes. Por ello se decidió realizar una revisión acerca de los elementos más importantes al respecto, con el objetivo de actualizar los conocimientos existentes sobre el tema. Estos precursores comprenden tres entidades que, por su fisiopatología, pueden estar presentes en la historia natural de esta afección: Desprendimiento de vítreo posterior, degeneraciones periféricas y desgarro de retina (sintomáticos y asintomáticos). Además, algunas situaciones de riesgo como la cirugía de catarata, la capsulotomía posterior con YAG-láser, los traumatismos y la miopía alta pueden favorecer también al desprendimiento de retina. Estos precursores, por lo general, se hacen más evidentes después de los 40 años, sin predilección por sexo o características raciales y están muy relacionadas con cambios vítreos o su licuefacción. El conocimiento básico y actualizado de estas entidades, así como de los factores de riesgo asociados al desprendimiento de retina es importante para el adecuado manejo y el control de las complicaciones. En la revisión se describen con claridad los pilares fundamentales para el diagnóstico y tratamiento de este tipo de situaciones clínicas

The changes and the vitreous retinal anatomical variations predispose to rhegmatogenous detachment of the retina, so knowing them is very important for the adequate treatment of patients. Therefore, it was decided to make a review on the most important elements, with the objective of updating the existing pieces of knowledge on the topic. These precursors include three entities that, because of their physiopathology, can be present in the natural history of this illness: detachment of posterior vitreous, peripheral degeneration and retinal tear (symptomatic and asymptomatic). Additionally, some risk situations such as cataract surgery, posterior capsulotomy with YAG-laser, traumas and high myopia may also favor the retinal detachment. These precursors became more evident after the 40's, without sex or race preferences, and they are closely related to vitreous changes or to their liquefaction. The basic updated knowledge about these illnesses as well as the risk factors associated to the retinal detachment is important to adequate management and control of complications. The review clearly described the fundamental pillars in diagnosis and treatment of this type of clinical situations

Fibrose sub-retiniana progressiva: relato de casos / Progressive subretinal fibrosis: case reports

A síndrome da fibrose sub-retinina é uma doença rara e considerada como parte de um grupo de condições que recebem a denominação de síndrome dos pontos brancos. No entanto, alguns autores a consideram como uma entidade distinta dessas outras doenças com características próprias. Com os casos apresentados, podemos observar muitas dessas características já descritas, como localização e aspecto clínico das lesões, sua evolução e o prognóstico visual final. Seu diagnóstico é muito importante a se considerar em diversos tipos de uveíte, pois o tratamento precoce pode evitar o acometimento bilateral.

The subretinal fibrosis syndrome is a rare disease and is considered part of a group of conditions that are denominated white dots syndrome. However, some authors consider it like a distinct entity from the others diseases with you own features. With these cases we can behold many features already described, like localization and clinical aspect of the lesion, your evolution and the final visual prognosis. It's diagnostic is very important to consider in a varied type of uveitis, because the treatment can avoid the bilateral involvement.

Tratamento cirúrgico da retinopatia diabética / Surgical management of diabetic retinopathy

A retinopatia diabética é a causa mais frequente de cegueira na população ativa nos países desenvolvidos. A prevalência da retinopatia diabética aumenta com a duração da diabetes, e praticamente 100% dos pacientes com diabetes tipo I (DM I) e mais do que 60% dos pacientes com o tipo II (DM II) apresentarão algum sinal de retinopatia após 20 anos. Além de um controle sistêmico rigoroso dos níveis glicêmicos, lipídicos, colesterol e da pressão arterial, o exame oftalmológico de rotina, com a identificação precoce da retinopatia diabética, podem detectar anormalidades em estágios primários, o que possibilita o tratamento ainda na fase inicial do problema; o uso adequado da fotocoagulação e a utilização da terapia antiangiogênica pode reduzir o número de pacientes com hemorragia vítrea ou descolamento tracional da retina. Infelizmente, em vários pacientes, a retinopatia progride mesmo com as melhores condutas tomadas pelo paciente e pelo oftalmologista, embora vários olhos podem se beneficiar com o tratamento cirúrgico, a vitrectomia posterior via pars plana. Esta revisão apresenta as indicações atuais para cirurgia vitreorretiniana em pacientes portadores de retinopatia diabética proliferativa...

Diabetic retinopathy is the leading cause of blindness among the working population in the developed world. The prevalence of diabetic retinopathy increases with duration of diabetes, and nearly 100 percent of patients with type I diabetes and more than 60 percent of those with type II have some signs of diabetic retinopathy after 20 years.A number of approaches have proved to be useful in the treatment of diabetic retinopathy, such as laser photocoagulation and tight systemic control of blood glucose, lipids, cholesterol and blood pressure. Unfortunately, in many patients the retinopathy progresses in spite of the best efforts on the part of the patient and of the ophthalmologist. Many such eyes may be helped by vitrectomy surgery, however.About 5 percent of patients with proliferative diabetic retinopathy, as well as carefully selected patients with diabetic maculopathy, require pars plana vitrectomy, despite ostensibly adequate laser treatment and good glycemic and hypertensive control. This article reviews the current indications for vitreous surgery in severe diabetic retinopathy and strategies and techniques employed to minimize surgical complications...

Scleral buckle is good option for treatment of uncomplicated retinal detachment / Introflexão escleral é boa opção para tratamento de descolamento de retina não complicado

OBJETIVE: To describe the reattachment rate and visual acuity results of patients with uncomplicated rhegmatogenous retinal detachment who underwent segmental scleral buckle surgery. METHODS: Prospective case series of 100 patients with visual loss or symptoms (floaters and photopsia) of less than 30 days' duration scheduled for surgery. No patient had a retinal break greater than 30°, a retinal detachment larger than 2 quadrants or proliferative vitreoretinopathy. RESULTS: The 1-week, 1-month, and 6-month anatomical success rates were 93%, 100%, and 100%, respectively. Seven patients underwent one additional retinal detachment surgery (pars plan vitrectomy) after primary failure at 1-week follow-up. The preoperative, 1-month, and 6-month best correct visual acuity were 20/100, 20/80, and 20/50, respectively. The postoperative complications were: eyelid edema in 10% of the patients, transient ocular hypertension in 5%, macular pucker in 3%, transient diplopia in 3%, and hyphema (<0.5mm) in 1%. CONCLUSION: In patients with uncomplicated retinal detachment, segmental scleral buckle showed a very good anatomical and functional success, with a few number of major complications.

OBJETIVO: Descrever a taxa de reaplicação e os resultados da acuidade visual dos pacientes com descolamento de retina regmatogênico simples que se submeteram à cirurgia de introflexão escleral segmentar. MÉTODOS: Uma série de casos prospectivo de 100 pacientes com perda visual ou sintomas (floaters e fotopsia), com duração inferior a 30 dias, agendados para a cirurgia. Nenhum paciente apresentou uma ruptura da retina superior a 30°, um descolamento de retina maior que 2 quadrantes ou vitreorretinopatia. RESULTADOS: As taxas de sucesso anatômico em 1 semana, 1 mês e 6 meses foram de 93%, 100% e 100%, respectivamente. Sete pacientes foram submetidos à cirurgia de descolamento de retina adicional (vitrectomia via pars plana) após falha primária em uma semana de seguimento. A melhor acuidade visual pré-operatória, 1 mês, e de 6 meses pós-operatório foram 20/100, 20/80 e 20/50, respectivamente. As complicações pós-operatórias foram: edema palpebral em 10% dos pacientes, a hipertensão ocular transitória em 5%, pucker macular em 3%, diplopia transiente em 3%, e hifema (<0,5 mm) em 1%. CONCLUSÃO: Em pacientes com descolamento da retina sem complicações, a cirurgia de introflexão segmentar escleral mostrou um sucesso anatômico e funcional muito bom, com um número menor de complicações maiores.

simple way to clear the media for vitrectomy in eyes with corneal edema

Herein we introduce a simple approach for clearing an edematous cornea during vitreoretinal surgery in eyes with decompensated corneal endothelium, allowing the surgeon to postpone penetrating keratoplasty. This technique was performed in 3 eyes by filling the anterior chambers with air or silicone oil, and sufficiently cleared the media for completion of vitrectomy. This simple technique enables completion of the vitrectomy without a temporary keratoprosthesis and penetrating keratoplasty in eyes with corneal edema due to endothelial decompensation
