Comparative electroretinograms in argon laser and xenon arc panretinal photocoagulation.

A comparative trial of xenon arc and argon laser photocoagulation in the treatment of proliferative diabetic retinopathy.

We present the results of a randomised study comparing xenon arc and argon laser photocoagulation in the treatment of proliferative diabetic retinopathy. Our results show that when used in the way described below there is no significant difference between the effect of the 2 treatments on optic disc neovascularisation and visual acuity. We also compare the results of peripheral retinal ablation...

Xenon arc photocoagulation in the treatment of diabetic maculopathy.

Argon laser and xenon arc coagulation of malignant choroidal melanomata: histological findings in 6 cases.

In recent years the management of small malignant melanomata of the choroid has been a controversial subject. Conservative measures are particularly desirable in cases in which there is a small tumour not interfering with visual acuity in the only good eye. The measures advocated to avoid enucleation are photocoagulation,' 2 radiotherapy,' cryotherapy,7 diathermy,8 and local excision.9 Photocoa...

Fluorophotometric detection of intravitreal peroxides after panretinal laser photocoagulation.

PURPOSE To develop a highly sensitive method for in vivo quantitation of intravitreal peroxides by vitreous fluorophotometry with 2',7'-dichlorofluorescin (DCFH), a hydrogen peroxide (H2O2)-sensitive fluorescent dye, and to measure peroxides in the vitreous humor after panretinal laser photocoagulation (PRP). METHODS In the presence of H2O2 and lipid hydroperoxides, nonfluorescent DCFH was ox...

Comparison between panretinal photocoagulation and panretinal photocoagulation plus intravitreal bevacizumab in proliferative diabetic retinopathy.

BACKGROUND Patients with diabetes often develop ocular complications. The most common and most blinding of these complications, however, is diabetic retinopathy. The objective of this study was to compare the retinal neovessels regression in Proliferative Diabetic Retinopathy (PDR) treated with Pan Retinal Photocoagulation (PRP) versus panretinal photocoagulation plus Intra Vitreal Bevacizumab ...
