Color Vision Outcome after Phacoemulsification with Intraocular Lens Implant in Patients with Diabetes Mellitus

Objective: To determine the impaired color function in pseudophakic background diabetic retinopathy patient Methodology: After the ethical approval from The University of Faisalabad under ethical approval number TUF/Dean//2019/39 the cross-sectional study was conducted in the Ophthalmology department of Madina Teaching Hospital Faisalabad which is associated hospital of the The University of Faisalabad. 58 volunteers of both gender and age ranging between 35-75 years were studied through non-probability convenient sampling technique. Duration of study was September 2018 to February 2019. Visual acuity was tested from logmar at a 4 meter distance. Color vision was tested by conventional Farnsworth D15 test, along with slit-lamp and +70D lens to evaluate retinopathy severity, after proper consent of the patient. The test was performed after taking complete ocular, medical, surgical and drug history. Each pseudophakic eye was tested monocular and each subject was tested thrice. Results: Results were analyzed using SPSS version 22. Significant association was seen between the color vision in pseudophakic diabetic patient with background retinopathy (p<0.05), using Pearson Chi-Square. Color vision by conventional D-15 showed mean of ±2.17 and standard error of ±1.05. While pseudophakic group showed mean of ±1.05 and standard error of ± 0.116. Conclusion: There is color defect in pseudophakic diabetic with background retinopathy. The dyschromatopsia is more in the blue axis. Color vision defect (CVD) seen more in uncontrolled diabetic than controlled. Color vision defect (CVD) increases with the course of retinopathy. Color vision checking must be made an integral part of examination specifically in diabetic retinopathy patient.
