PURPOSE: To evaluate the changes in corneal topography after 20-gauge pars plana vitrectomy associated with scleral buckling for the repair of rhegmatogenous retinal detachment. METHODS: Twenty-five eyes of 25 patients with rhegmatogenous retinal detachment were included in this study. 20-gauge pars plana vitrectomy associated with scleral buckling was performed in all patients. The corneal topography of each was measured before surgery and one week, one month, and three months after surgery by computer-assisted videokeratoscopy. RESULTS: A statistically significant central corneal […]

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%, […]

The Ectopia lentis et pupillae is a rare genetic syndrome, congenital, autosomal recessive with variable expression, characterized by ectopia of the lens and the pupil, usually bilateral and symmetrical, but without systemic manifestations. The pathogenesis of this anomaly is still unknown, but there are theories that the change is mesodermal, neuroectodermal, combined or mechanical. This article presents a clinical case of a patient with ectopia lentis et pupillae, describing its clinical and genetic aspects, secondary ocular complications and differential diagnosis.

PURPOSE: To evaluate the characteristics and evolution of the retinal detachment developed after successful treatment of retinoblastoma. METHODS: A retrospective analysis of 220 consecutive patients treated for retinoblastoma from january 1978 to december 2008 disclosed two patients who developed retinal detachment during the follow-up. RESULTS: Retinal detachment was found in two patients several months after the treatment of retinoblastoma. Both were managed by surgery with restoration of their monocular vision. CONCLUSION: Surgical management of retinal detachment is indicated to preserve […]

The authors relate an uncommon complication of retinopexy with encircling scleral buckle employing Arruga Suture, that has evolved to scleral erosion and intraocular damage.

PURPOSE: To report the profile of Coats’ disease patients, referred to exclude retinoblastoma. METHODS: Retrospective study of medical charts from ten consecutive patients. Data evaluated include age at diagnosis, gender, chief complain, disease stage, treatment and evolution. RESULTS: Mean age at diagnosis was 43.9 months. Eight patients had stage 3B of the disease, one stage 3A and one 2B. From the eight patients with total retinal detachment (3B disease), seven were managed by observation one was submitted to unsuccessful retinopexy. […]

Retinoschisis diagnosis can be very difficult in atypical forms. Special exams are necessary to differentiate retinoschisis from other pathologies such as retinal detachment. Case Report: A 61-year-old black woman presented for routine examination. Fundus of the right eye reveled a superior periphery lesion extending to the posterior pole. The ultrassonography of the same eye showed a high reflective membrane. An inferior field absolute scotoma was detected. The OCT scan that was positioned at lesion in the outer retinal break demonstrated […]
