PHOTOCOAGULANT LASER TREATMENT IN DIABETIC RETINOPATHY: ADVANTAGES, RISKS, LIMITS
The present paper proposes to point out the major advantages of laser therapy in diabetic retinopathy, alongside with the presentation of main risks and failure causes of this surgical technique. Preventing blindness in patients with diabetes represents not only a national priority, but also a worldwide one, and the dynamics of therapeutical research within diabetic retinopathy has reached a unprecedented level. The high interest in this condition, specific to diabetes mellitus, is reflected in the substantially large number of clinical studies whose objective is the pathogeny and treatment of diabetic retinopathy [1, 2, 3, 4]. If there still are a lot of controversies regarding the pathogeny of diabetic retinopathy, with the various etiopathogenic theories, both supported and contested, worldwide scientists unanimously agree with the threat represented by this condition for the life of diabetes patients. OMS states a terrifying reality: worldwidely, in 2008, there were 1.74 million diabetic patients with extremely low vision (legal blindness) due to diabetic retinopathy. Diabetic retinopathy is the most frequent cause of the new blindness cases reported worldwidely, in the adult population aged between 20 and 74 years old . The arguments and counter-arguments against using photocoagulant laser in certain stages of diabetic retinopathy are based on the experience over a period of 7 years of the “Diabetic Eye” Department in Craiova and are supported by retinophotographic images and retinal tomographies in optical coherence (TOC).
