Key words: cystoid macular edema, ranibizumab, selective laser coagulation of retinal pigment epithelium.

The clinical efficacy of combination of intravitreal ranibizumab (IR) and selective laser coagulation of retinal pigment epithelium in diabetic cystoid macular edema was investigated by macular thickness (MT), foveal avascular zone (FAZ) and best corrected visual acuity (BCVA) during 12 months. There were 51 patient, 57 eyes, mean age — 59,5 (9,1) years with diabetes mellitus type I — 20patients, type II — 31 patient, mean blood glucose 9,9 (1,8) pM/l, mean diabetes duration — 15,0 (7,7) years. 1month after IR MT significantly decreased from (509,5+15,3) pm to 276+87pm and selective laser of retinal pigment epithelium was done to all patients. After 12 months MT was (311311+12,4) pm (p=0,000009 Newman-Keuls test), FAZ diminished from (1,128+0,038) mm2 do (1,037+0,043) mm2 (p=0,000009), BCVA improved from 0,23+0,02 to 0,33+0,03 (p=0,00009). BCVA improved on 23 eyes (40,3 %), stabilized on 14 eyes (24,6) fnd worsened on 20 eyes (35,1 %).
