PG - 157-163 LID - 10.4103/jovr.jovr_160_17 [doi] AB - PURPOSE: The current study aimed to evaluate changes in peripapillary retinal nerve fiber layer (RNFL) thickness in diabetic patients with bilateral proliferative diabetic retinopathy (PDR) after receiving panretinal photocoagulation (PRP) or intravitreal bevacizumab (IVB) with PRP. METHODS: Ocular examination and peripapillary optical coherent tomography (OCT) were performed for each patient at baseline, 1, 3, 6, and 10 months after treatment. Both eyes of each patient were randomized into either PRP or PRP + IVB group. RESULTS: Sixty-four eyes (32 patients) were enrolled in this randomized clinical trial. In the PRP group, global RNFL thickness initially increased and reached statistical significance in the third month (from 105.9 +/- 21.4mum at baseline to 119 +/- 41.6mum at 3 months, P = 0.03). Subsequent decline was observed with no significant difference from baseline at 10 months (106 +/- 19.3mum, P = 0.914). There were no statistically significant changes in the PRP + IVB group (from 101.7 +/- 22.2mum at baseline to 109.3 +/- 26.9mum at 3 months, P = 0.996 and 101.9 +/- 16.5mum at 10 months, P = 0.999). In the latter group, slight increase in RNFL thickness was observed in the first month (107.7 +/- 21.1mum). RNFL thickness was similar to baseline in the two groups at month 10, with the exception of significant increase in superior-temporal sector in the PRP group (145.3 +/- 13.4mum vs. 127.2 +/- 17.3mum, P = 0.045). CONCLUSION: Compared to eyes treated with PRP, eyes treated with adjunctive IVB showed less significant post-treatment changes in RNFL thickness.
