RESUMO
PURPOSE: To analyse baseline imaging characteristics and factors affecting poor visual acuity in diabetic papillopathy. METHODS: This was a retrospective, observational study conducted at a tertiary eye care centre in eyes with a diagnosis of diabetic papillopathy. Demographic data including age, gender, duration of diabetes, type of diabetes, HbA1c values and other systemic co-morbidities were recorded. Baseline best corrected visual acuity (BCVA), and various imaging characteristics were noted. RESULTS: 37 eyes of 22 patients with diagnosis of diabetic papillopathy were included [mean age of 46.6 ± 13.5 years, five (22.7%) females and 17 (77.3%) males]. Bilateral involvement was seen in 15 (68.2%) patients. The mean baseline BCVA was 0.51 ± 0.49 logMAR (Snellen equivalent 20/60). Two eyes (5.4%) had features of concurrent mild NPDR, 9 eyes (24.3%) had moderate NPDR, 10 eyes (27.03%) had severe NPDR while 16 (43.2%) other had PDR. All eyes had optic disc edema while 4 had disc pallor at presentation. Telangiectatic vessels/ neovascularisation of disc was present in 17 eyes (45.9%) detected either clinically or on optical coherence tomography (OCT) angiography. 11 (29.7%) eyes had a peripapillary cuff of subretinal fluid accompanying the disc edema. Sixteen eyes (43.2%) had centre involving macular edema seen on OCT. In eyes with a macular edema, the mean central macular thickness was 407.4 ± 71.42 microns at baseline. On assessing the baseline factors that contribute to the final visual acuity, presenting visual acuity was the only variable found to be statistically significant. CONCLUSION: Although described to have good visual outcome, eyes presenting with poor visual acuity tend to have worse vision on follow up. This may aid in prognosticating and guiding management plan.
