Ultra-Widefield Fluorescein Angiography-Based Targeted Retinal Photocoagulation Versus Conventional Panretinal Photocoagulation in the Preservation of Visual Function and Regression of Proliferative Diabetic Retinopathy

Ultra-Widefield Fluorescein Angiography-Based Targeted Retinal Photocoagulation Versus Conventional Panretinal Photocoagulation in the Preservation of Visual Function and Regression of Proliferative Diabetic Retinopathy

Proliferative diabetic retinopathy is a vision-threatening disease that can lead to irreversible visual loss. The treatment options for proliferative diabetic retinopathy are anti-VEGF injection and retinal photocoagulation. The study aims to compare ultra-widefield fluorescein angiography-based targeted retinal photocoagulation and panretinal photocoagulation in the treatment of proliferative diabetic retinopathy.

Inclusion Criteria:

• proliferative diabetic retinopathy (PDR) with neovascularization on the disc or elsewhere in the retina

Exclusion Criteria:

• Participants with a history of previous history of:
• retinal photocoagulation
• vitreoretinal surgery
• tractional retinal detachment
• epiretinal membrane
• vitreomacular traction
• glaucoma
• uveitis
• media opacities like cataract, corneal opacity, vitreous hemorrhage
• anti-VEGF injections in last 3 months
