Abstract
Objective To observe the macular morphology changes before and after phacoemulsification and IOL implantation in diabetic patients by spectral-domain optical coherence tomography (SD-OCT).Methods Fifty eight patients (60 eyes) received phacoemulsification and IOL implantation for cataract,including 29 diabetics (31 eyes) and 29 non-diabetics(29 eyes).Macular SD-OCT scans were performed on all patients before and 1 month after operation.The changes of macular and related influence factors,including age,sex,smoking history,hypertension,hyperlipidemia,HbA1c and diabetes were analyzed.Results The most obvious changes of macular thickness in two groups were observed at 1 month after the surgery.The central subfield thickness (CST) was positively correlated with diabetic duration (before surgery:r =0.53,P＜0.01,1 month after surgery:r=0.69,P=0.04).The IogMAR best corrected visual acuity (BCVA) 1 month after surgery was positively correlated with diabetic duration(r=0.47,P＜0.01),HbA1c(r=0.38,P＜0.01),CST before surgery (r=0.61,P＜0.01) and smoking history(r=0.28,P＜0.05).Multiple regression analysis showed that CST before surgery was independent risk factor of BCVA(P＜0.05).Conclusion CST of diabetes patients after phacoemulsification will reach a peak at 1 month after surgery.CST before surgery is correlated with the diabetic duration,which is the independent risk factors of BCVA after operation.关键词
