• Participant gender: All

Summary

Photocoagulation is the standard treatment in the focal EMCS, disrupts vascular leakage and allows the pigment epithelium remove the intraretinal fluid is effective in reducing the incidence of visual loss but can reduce contrast sensitivity and retinal sensitivity, the characteristics of the function can be reduced such as setting (location and stability) are relevant to the quality of the patient's vision parameters, reading comprehension, especially the ability, duration of diabetic macular edema, could have a significant impact on survival and / or the functional reserve of the macular cells subjected to mechanical and toxic stress-induced edema. It seems that in the treatment of patients with EMCS, photoreceptor damage occurs as a recent phenomenon, and can precede neurodegeneration retinal photoreceptor loss, whereby visual function can be decreased. An adjunctive treatment as Dorzolamide facilitating effect helping resorption of intraretinal fluid through EPR and reduce adverse events that is the loss of contrast sensitivity and retinal sensitivity, response time of photocoagulation treatment could be reduced to the patient, because the rate of resorption of intraretinal fluid is facilitated and thus the duration of the response, also could reduce damage to vision caused by the inadequacies of the photoreceptors during the evolution of macular edema avoiding moderate visual loss, there by increasing the quality of life in terms of improving the quality of vision in diabetic patients. In addition to obtaining a specific adjuvant treatment with photocoagulation is helpful for focal edema in diabetic and a new level using dorzolamide in retina Dorzolamide as adjunctive therapy after focal photocoagulation is more effective than placebo in improving visual function in patients with diabetic macular edema
