ABSTRACT
Importance: To evaluate the impact of panretinal photocoagulation (PRP) on the quality of life in patients of proliferative diabetic retinopathy (PDR). PRP affects various visual functions like visual acuity, contrast sensitivity, glare, visual fields. This study describes the impact of PRP on the visual functions and the quality of life in Indian population. Objective: To evaluate the impact of panretinal photocoagulation (PRP) on the quality of life in patients of proliferative diabetic retinopathy (PDR). Design: Prospective interventional study. Setting: Single centre study conducted at a tertiary eye hospital in North India. Participants: Sixty eyes of 30 patients of PDR without diabetic macular edema (DME) and planned for PRP were evaluated before PRP and 3 months after it for the following: vision for distance and near (Log Mar Chart), indirect ophthalmoscopy, visual field testing (HVF 120’2), contrast sensitivity (Low Contrast Flip Chart), grading of photophobia and quality of life (QOL) related questionnaire (IND-VFQ33). Results: There was a statistically significant worsening in contrast sensitivity (p= 0.02) and visual fields (p= 0.003). There was no statistically significant change in the distance and near vision (p= 0.94 and p= 0.51) as well as in photophobia (p= 0.06). The assessment of the QOL parameters showed no statistically significant worsening on the general functioning (p= 0.16), psychosocial impact scale (p= 0.17) and visual symptoms scale (p= 0.12). Conclusion: PRP for PDR causes a decrease in contrast sensitivity, visual fields with a possible increase in photophobia but this does not have a significant impact on the QOL of diabetic patients.
