The Relationship Between Early Postoperative Visual Acuity And The Thickness Of Macular After Phacoemulsification In Diabetics

Objective: Investigate the relationship between early postoperative best vision and Central subfieldthickness and macular volume, macular area average retinal thickness of diabetic cataract surgery, who’sthe mode of operation,preoperative preparation and postoperative treatment are in the same situation,and toexplore the relationship between the postoperative macular center concave retinal thickness and macularvolume, and macular area average retinal thickness and the correlation between early postoperative bestcorrected visual acuity.Methods: Patients (84eyes) who received cataract operation were divided into diabetic group including43eyes,which are43eyes, male20cases (22eyes), female19cases (20eyes)，and simple cataract groupwhich are41eyes,male,22cases (22eyes), female18cases (19eyes) from January to August in2013. Werecorded central macular retinal thickness (CST) and macular volume (CV) and macular area averagethickness of retina, and early postoperative best corrected visual acuity in the two groups of cataractsurgery patients with optical coherence tomography, and analysis the indicators and the relationshipbetween the postoperative best corrected visual acuity.Results: The relationship between early postoperative best corrected visual acuity (BCVA) and macularcentral retinal thickness (CST) in diabetes patients showed a negative correlation (r=-0.456, P=0.02).Thecorrelation coefficient between macular volume and BCVA (CV) is r=-0.568,(p=0.00),which suggested theresults was statistically significant. The correlation coefficient between the partition retinal averagethickness of macular is r=-0.525,(p=0.000<0.05),which suggested the result was statistically significant. Inthe simple cataract patients,the correlation coefficient between the postoperative best corrected visualacuity (BCVA) and macular central retinal thickness (CST) is r=-0.368，（P=0.068>0.05),which suggestedthe result was not statistically significant. The correlation coefficient between macular volume (CV) andBCVA is r=-0.199,(P=0.212>0.05),which prompt results no statistical significance. The relationshipbetween the macular area average retinal thickness and BCVA is r=-0.320,(P=0.042<0.05),which promptresult was statistically significant.Conclusion: The BCVA of diabetic patients who after operation was found to be inversely associated withcentral macular retinal thickness, macular volume and postoperative early negative correlation bestcorrected visual acuity, macular area average retinal thickness and early postoperative best corrected visualacuity showed a negative correlation. The BCVA of simple cataract patients negatively correlated themacular area average retinal thickness, but it has no obvious correlation with macular foveal thicknessand macular volume and early best corrected vision.Early vision and each index of macular in patients with diabetic cataract are more closely related thansimplex cataract，which is a negative correlation. Macular volume, center for macular area average retinalthickness and macular retinal thickness are effective predictor of early postoperative best corrected visualacuity.
