This study was performed to evaluate the functional and anatomic outcomes of focal macular laser photocoagulation in eyes with non-center involved macular edema (non-CI ME). Forty-nine eyes of 43 patients with non-CI ME were included. Focal macular laser photocoagulation was conducted on twenty-nine eyes of 25 patients, while 20 eyes of 18 patients with non-CI ME were followed without treatment...

PURPOSE To evaluate and characterize the New-World squirrel monkey as a primate model for experimental choroidal neovascularization (CNV) studies and to compare it with the current Old-World macaque monkey model. METHODS Fibrovascular tissues (FVT) were elicited in 12 maculae of seven squirrel monkeys by laser photocoagulation using optimized laser parameters (532 nm, 0.05 second, 75 micro m,...

INTRODUCTION The aim of this review was to describe the use of optical coherence tomography (OCT) in the diagnosis and management of retinal angiomatous proliferation (RAP) in patients with age-related macular degeneration (AMD). MATERIALS AND METHODS We reviewed the tomographic characteristics of the eyes affected by RAP seen at our institution and imaged by OCT. Some eyes with RAP were also...

The concept of retinal photocoagulation was introduced by Meyer-Schwickerath for the treatment of diabetic retinopathy in the 1950s and used with some success in the 1960s. The xenon arc photocoagulator utilized for this purpose was large, polychromatic, inefficient, and difficult to operate, prompting a search for a better method of treatment. Further progress was achieved when ruby,1 argon io...

To report a single case of improvement on choroidal metastasis of breast cancer after laser photocoagulation. A 52-year-old female patient who complained of visual disturbance of the right eye with multiple states of metastasis of breast carcinoma. On initial examination, the right best-corrected visual acuity was 0.63. Right fundoscopy revealed an elevated mass-like lesion temporal to the macu...

PURPOSE To evaluate the inhibitory effect of chlorogenic acid on laser-induced choroidal neovascularization (CNV) in a rat model. METHODS Intraperitoneal injection of chlorogenic acid (10 mg/kg) was initiated one day prior to laser photocoagulation and continued for eight days. Eyes were removed 14 days after laser photocoagulation. Fluorescein angiography was employed at seven and 14 days to...

BACKGROUND Diabetic retinopathy (DR) is the most common microvascular complication of diabetes. It can lead to significant visual loss. The aim of this study was to determine the frequency and clinical profile of diabetic retinopathy, and assess the outcomes of laser photocoagulation therapy in a diabetic population in Cameroon. METHODS We carried out a prospective cohort study during 24 mont...

Diabetic retinopathy is a leading cause of visual impairment and blindness in developed countries due to macular edema and proliferative diabetic retinopathy (PDR). For both complications laser treatment may offer proven therapy: the Diabetic Retinopathy Study demonstrated that panretinal scatter photocoagulation reduces the risk of severe visual loss by >50% in eyes with high-risk characterist...

PURPOSE This study aimed to evaluate the outcome of transpupillary diode laser photocoagulation for retinopathy of prematurity (ROP) at one institution in Romania. METHODS This retrospective case series included all infants who received indirect diode laser photocoagulation for ROP between January 1, 2006, and December 31, 2012. RESULTS The 160 eyes of 83 infants were classified into two ca...

Electroretinographic (ERG) responses were measured in diabetic patients before, during, and after panretinal photocoagulation treatment with argon laser. The laser applications reduced considerably the amplitudes of the a and b waves of the ERG. Moreover, the relationship between the amplitude of the b wave and that of the a wave was severely affected, resulting in ERG responses of abnormal pat...
