Brief Summary
The purpose of this study is to evaluate the optic nerve head changes consequent to panretinal photocoagulation done for diabetic retinopathy.
Detailed Description
Panretinal photocoagulation thermally ablates the retina to effect the regression of the neovascular process seen with diabetic retinopathy.2-6 Photocoagulative damage also damages the nerve fiber lay...
Eligibility Criteria
Inclusion
- Any patient with proliferative diabetic retinopathy or severe non-proliferative diabetic retinopathy otherwise undergoing panretinal photocoagulation for treatment.
Exclusion

- Patients with media opacities (significant cataract, corneal opacity, vitreous hemorrhage) precluding imaging of the optic nerve.
- No PRP done in the previous 6 months.
