Photocoagulation is an accepted method of local treatment for proliferative diabetic retinopathy. It has been shown that 73 25 per cent. of eyes with proliferative diabetic retinopathy have new vessels on the optic disc at the initial visit (Taylor and Dobree, I970). These vessels cannot be treated directly by photocoagulation. Aiello, Beetham, Balodimos, Chazan, and Bradley (I969) treated all ...

f l t i s e r m s c i t d o o ( t m s a e Diabetic retinopathy (DR) remains the leading cause of blindness among working-age people in developed countries1. Tight control of blood glucose levels and blood pressure is essential for preventing or arresting DR development. However, therapeutic objectives are difficult to achieve and DR therefore occurs in a high proportion of patients. Once DR app...

PURPOSE To establish whether differences in the assessment of diabetic macular oedema (DME) with either optical coherence tomography (OCT) or stereoscopic biomicroscopy lead to variability in the photocoagulation treatment of DME. METHODS The differences in the assessment of DME with either OCT or stereoscopic biomicroscopy were analysed by calculating the surface areas and the overlap of ret...

INTRODUCTION Diabetic macular edema (DME) is a common cause of visual acuity deterioration among patients with diabetes. Laser photocoagulation still remains the most common treatment of DME and diabetic retinopathy. OBJECTIVES The aim of the study was to assess mean central retinal sensitivity among patients with DME before and after laser photocoagulation treatment. Additionally, we estimat...

Background: A pyogenic granuloma (PG) is a common benign vascular lesion found in the oral cavity. The gold standard treatment of this lesion, comprising surgical excision and elimination etiological factors, cannot avoid tooth loss case an aggressive granuloma. Because prominent properties 980 nm 635 diode lasers photocoagulation photobiomodulation, we applied these wavelengths large wi...

Aims: To compare the t reatment parameters , outcomes, and patient comfort levels following patterned scanning laser photocoagulation versus single spot laser photocoagulation. Methods: This prospective randomized controlled trial involved 18 eyes of 16 patients. Patients with retinal diseases requiring laser photocoagulation to the retina were recruited and randomized to undergo laser photocoa...

SUMMARY STATEMENT Direct photocoagulation reduces the central foveal thickness (CFT) in cases with chronic branch retinal vein occlusion (BRVO) of longer than 12 months duration. Photo-coagulation might be effective for chronic macular edema due to branch retinal vein occlusion. BACKGROUND The aim was to investigate the effect of direct photocoagulation for treating chronic macular edema asso...

This report is of a patient with ischemic central retinal vein occlusion who underwent panretinal photocoagulation. Serial measurements of the retinal nerve fiber layer were performed using scanning laser polarimetry, which showed increased thickness of the peripapillary region as early as 2 weeks after the panretinal photocoagulation.

PURPOSE Macular edema is one of the serious side effects associated with panretinal photocoagulation (PRP). The inhibitory effect of triamcinolone acetonide (TA) on leukocyte-endothelial cell interactions in vivo after PRP was evaluated. METHODS Argon laser photocoagulation was performed in one half of the retinas in male Brown Norway rats. Experimental rats were injected with 2 mg TA (50-mic...

AIM To evaluate the use of scatter laser photocoagulation to prevent radiation related retinopathy, maculopathy, and loss of vision. METHODS This was an interventional case series. 66 eyes with posterior choroidal melanomas treated by ophthalmic plaque radiation therapy were reported. Of these patients, 50 were selected because they developed radiation retinopathy; 45 of these were treated wi...
