Abstract
INTRODUCTION. The purpose of this study is the evaluation of the photocoagulation impact on central retina in diabetic retinopathy.
MATERIAL AND METHODS. 101 patients (200 eyes), age varied from 23 to 72 years, 47 women and 54 men with insulin-dependent and insulin non-dependent diabetes were analyzed. On the basis of detailed ophthalmology and angiography examination diabetic maculopathy were found in 168 eyes. The focal macular edema was stated in 105 eyes (62.5%), diffuse maculopathy in 54 eyes (32.1%) and ischemic maculopathy in 9 eyes (5.4%). Patients were treated with argon laser Coherent 920, in accordance with DRS and ETDRS recommendations. The effects of laser therapy were estimated in 1.2 to 4.4 years after photocoagulation.
RESULTS. In 88,6% eyes with focal macular edema and in 83.3% eyes with diffuse maculopathy we noticed an improvement after the photocoagulation. Stabilization was found in 8.6% eyes with focal macular edema and in 11.1% eyes with diffuse maculopathy. Deterioration was found in 2.8% eyes with focal maculopathy and in 5.6% eyes with diffuse maculopathy. Ischemic maculopathy was stabilized in 60%, improved only in 20%. The amount of microvessels decreased in 81.8% eyes, the amount of hard exudates in 77%, intraretinal blood extravasations in 24.2% eyes and zones of lack of perfusion only in 3.6%.
CONCLUSION. The positive results of photocoagulation, especially in focal and diffuse maculopathy, justify the application of laser treatment as a method of choice in diabetic retinopathy.
