Green Laser Photocoagulation Study in Proliferative Diabetic Retinopathy

Comparative Study of Indigenous Green Laser With Already Available Green Laser in Proliferative Diabetic Retinopathy

To Demonstrate that indigenous green laser produces similar treatment effect on the retina when compared with already available green laser.

Proliferative Diabetic Retinopathy is ocular pathology in poor glycaemic controlled Diabetic patient Characterized by micro-vascular pathology with capillary closure in the retina leading to hypoxia of tissue there by formation of immature vessels to provide better oxygenation of retinal tissue.

In this randomized double blinded study a convenient sample size of 24 eyes assigned to compare indigenously developed green laser with already available green laser.

Inclusion Criteria:

• Patients more than 18 years of age
• Eyes with proliferative diabetic retinopathy requiring laser photocoagulation

Exclusion Criteria:

• Eyes with media opacities not allowing proper fundus photography or adequate laser photocoagulation
• Patients requiring more than two sessions of laser photocoagulation
• Patients who had undergone previous laser photocoagulation
• Patients who had undergone any previous vitreo-retinal surgery
