Comparison of targeted retinal photocoagulation versus pan-retinal photocoagulation in the treatment of proliferative diabetic retinopathy

The aim of this study was to compare the efficacy of targeted retinal photocoagulation (TRP) with pan retinal photocoagulation (PRP) in the treatment of proliferative diabetic retinopathy (PDR). A total of 100 patients with PDR were enrolled in the study. The patients were divided into the TRP group (n=50) and the PRP group (n=50). The primary outcome measure was the proportion of patients who achieved a complete regression of PDR. Secondary outcome measures included the effect of TRP or PRP on visual acuity, visual fields and the need for further treatments. The results showed that the TRP is an effective treatment modality in proliferative retinopathy regression (86%) like PRP group (72%). The TRP group also showed a visual acuity improvement (0.19 logMAR) compared to the PRP group (mean improvement of 0.13 logMAR) with good preservation of visual fields. There were no significant differences in the need for further treatments between the two groups. These results suggest that TRP is safe treatment option for PDR. Material and Methods: This study was conducted in the Department of ophthalmology Khyber Teaching Hospital Peshawar from January 2020 to July 2021. A total of 100 patients with proliferative diabetic retinopathy were included in the study
