Title: Quantitative assessment of macular edema after retinal reattachment
Abstract: Objective To investigate the macular edema after retinal reattachment(RD).Methods We quantitatively measured the macular thickness of 58 postoperative patients(58 eyes) with rhegamatogenous RD who were operated successfully by retinal thickress analyzer(RTA),and compared with the conditions which including:macular detachement and macular attachment;the size and the site of holes;and subretinal fluid draining. Results Identified with RTA,the occuring rate of macular edema after retinal reattachment was 31%;31.8% and 30.6% in the patients whose diopter was less or more than -6.0D before surgery, (P0.05);the occurring rate of macular edema was 33.3% and 30.6% in the patients who whether or not underwent subretinal fluid draining respectively(P0.05);it was also found 38.7% eyes with macular edema that had superior quadrant holes,and 22.2%eyes had inferior quadrant holes(P0.01),the size of 19.4% holes were bigger than 3PD and 3.2% holes were less than 1PD (P0.01).Conclusion We could measure and observe macular edema accurately by applying RTA.The size and site of holes correlated well with CME after retinal surgery,but macular edema did not relate with the diopter of the eyes and subretinal fluid draining.The occurring mechanisms of macular edema are obstacle of blood circulation,intraocular inflammatory reaction by cryotreatment and the following macular epimembrane.
