RESUMO
Abstract?AIM:To report the incidence of post-operative c ystoid macular edema ( pCME ) in patients with or without diabetes and its correlation with c umulative dissipated energy ( CDE ) and phaco -time after uncomplicated phacoemulsification.?METHODS:In the study 116 nondiabetic ( Group A) and 101 d iabetic patients ( Grou p B) underwent phacoemulsification.Preoperatively none of the groups ( A+B ) had signs of maculo pathy or diabetic macular edema documented by spectral-domain optical coherence tomography ( SD -OCT ) and fundus fluore scein angiography ( FFA ) . Phaco metrics were documented after surgery.FFA was performed two months after each operation . Patients with indications of pCME were reassessed with SD-OCT.?RESULTS: The incidence o fpCME after uncomplicated pha coemulsification was statistically significant difference between the two groups (15.8% in Group B versus 6.9%in Group A, P =0.03 <0.05).The subclinical pCME appeared in 19 out of 24 patients.There was a significant correlatio n between parametric values ( CDE, phaco -time, hardness of the lens ) and pCME occurrence. Glycosylated Hemoglobin ( HbA1c ) blood level s was statistically significant difference ( P =0.005 <0.05 ) between the patients who developed or not pCME. Cystoid mac ular edema did not correlate with the axial length of the eye.? CONCLUSION: There was statis itcally significant differen ce in the incidence of pCME after uneventful phacoemulsification between nondiabetic subjects and diabetics. Most of these patients with pCME had subclinical appearance.CDE and phaco-time data were important factors and predictors to pCME.Good glycemic controls prevent the incidence of pCME.
