BACKGROUND Facial telangiectasia due to photodamage is a common disfiguring condition in modern society. Over the past 10 years yellow light laser photocoagulation has become the treatment of choice. OBJECTIVE To compare the effectiveness of copper vapor laser alone with combined microsclerotherapy and copper vapor laser in the treatment of facial telangiectases. METHODS Two hundred thirty-...

PURPOSE To evaluate visual results and vitreoretinopathy and retinal detachment frequencies in patients with and without prophylactic pre-equatorial retinal photocoagulation, who underwent clear lens extraction (CLE) to correct myopia. METHODS Thirty-five patients (60 eyes) that underwent clear lens extraction at the "Fundação Altino Ventura" had median follow-up of 20.5 months. They were cla...

PURPOSE To determine the effect of atorvastatin, an HMG CoA reductase inhibitor, on experimental choroidal neovascularization (CNV) induced by laser photocoagulation in mice. METHODS CNV was induced by laser photocoagulation in normal wild-type mice. The mice received either oral atorvastatin 10 (AS10 group) or 20 (AS20 group) mg/kg per day 3 days before and after laser application; 1 (AS1) a...

BACKGROUND To evaluate the long-term outcomes of Argon laser photocoagulation compared to surgical direct cyclopexy in small-size cyclodialysis cleft patients. METHODS This is a retrospective study. Small-size cyclodialysis cleft patients who underwent Argon laser photocoagulation and surgical direct cyclopexy were reviewed. The mean follow-up period were 82.4 (range, 61 - 145) months and 99....

AIMS Sight-threatening diabetic retinopathy has been treated with photocoagulation for decades but the mechanisms behind the beneficial clinical effects are poorly understood. One target of irradiation and a potential player in this process is the retinal pigment epithelium (RPE). Here we establish an in vitro model for photocoagulation of human RPE cells. METHODS ARPE-19 cells were exposed t...

DIABETIC retinopathy is a common cause of blindness. The introduction of photocoagulation treatment has stimulated interest in this condition and several well designed and properly controlled studies have shown that either xenon arc or argon laser photocoagulation therapy can arrest or delay the progression of diabetic retinopathy.1-7 This treatment is now available at many centres in the UK, a...

Laser treatment for retinopathy of prematurity (ROP) has been proven to be beneficial. We present a case of uncommon, progressive anterior eye segment complication treated with diode laser photocoagulation for ROP which subsequently required surgical management. A 1210 g premature infant, born at 28 weeks of gestation, had bilateral stage 3 threshold ROP on his first screening, at 5 weeks of ag...
