The efficacy of panmacular laser coagulation of diabetic edema of the macula in presence of intraretinal cysts depending on the initial morphological and functional conditions

Introduction. Efficacy of panmacular laser coagulation (LC) in the treatment of diabetic macular edema (DME) with intraretinal cysts is low and depends on the terms of laser treatment. Purpose ? to explore the efficacy of LC of DME with intraretinal cysts depending on primary morphological and functional condition of macula. Material and methods. 56 eyes with intraretinal cysts in diabetic macular edema zone (47 patients, 23,4 % type 1 of diabetes mellitus, 76,6 % type 2 of diabetes mellitus) were divided by macular thickness (MT), foveal avascular zone square (FAZ) and visual acuity (VA) into tree groups, which differ significantly in all three parameters. 1 group (11 eyes): VA ? 0,68(0,07), MT ? 353(46) fim, FAZ ? 0,69(0,15) mm2, 2group (33 eyes): VA ? 0,43(0,06), VN ? 536(71) fim, FAZ ? 0,93(0,1) mm2, 3 group (12eyes): VA ? 0,24(0,06), MT ? 710(58)/um, FAZ ? 1,32(0,11) mm2. Results. Visual stabilization or improvement were regarded as a positive result (PR). During 1 year after panmacular laser coagulation in the 1 group PR was achieved in 72,7% (8 eyes), in the 2 group PR was achieved in 63,6 % (21 eyes), and in 3 group PR was not achieved at all. Conclusion. Thus, in cases of hard cystoid diabetic macular edema the searching of other methods of treatment is necessary.
