Introduction:
Rhegmatogenous retinal detachment (RRD) is the most common type of retinal detachment. Purpose of this study is to evaluate the possible association of ARMS2 (age-related macular susceptibility 2) A69S and CFH (complement factor H) Y402H polymorphisms with post-surgical macular complications.
Materials And Methods:
One hundred and two RRD patients with macular involvement and proliferative vitreoretinopathy grade A prospectively were enrolled in the study. All patients were genotyped for two polymorphisms of CFH Y402H and ARMS2 A69S by applying Polymerase Chain Reaction (PCR)-Restriction Fragment Length Polymorphism (RFLP). Scleral buckling or deep vitrectomy performed based on surgeon decision. Optical coherence tomography (OCT) for all patients was performed on three, six, and twelve months after operation.
Results:
The ARMS2 A69S GT genotype showed significant association with postoperative cystoid macular edema (OR = 3.11, P = 0.039). Logistic regression analysis showed that the effect of ARMS2 GT vs GG genotype remained significant on CME after confounding factors correction. (ARMS2 GT vs GG OR = 4.79, p value = 0.035). No association was observed between studied genotypes and postoperative persistent subfoveal fluid, macular atrophy, and macular epiretinal membrane.
Conclusions:
The ARMS2 A69S GT genotype was significantly associated with postoperative cystoid macular edema in RRD cases with macular involvement.
