LASER stands for Light Amplification by Stimulated Emission
of Radiation. It is a high energy beam of light which can be
used to treat various retinal disorders.
It is a non-invasive OPD (Out-patient Department)

WHY ARE RETINAL LASERS DONE?

- Proliferative Diabetic Retinopathy
- Diabetic Macular Edema
- Neovascularization due to retinal vein occlusions
- Retinal Vasculitis
- Central Serous Chorio-retinopathy
- Peripheral Retinal Degenerations/ holes/ tears
- Retinopathy of Prematurity
- Retinal artery Macroaneurysm
- Laser done to areas of no/ low blood flow
- Away from centre of retina
- PRP is done for disorders like - diabetic retinopathy,
vein occlusions, vasculitis, retinopathy of prematurity
- Laser done to areas of leakage.
- Focal Laser is done for conditions like - Diabetic
macular edema, Central serous chorio-retinopathy,
Retinal artery macroaneurysm
- Laser done to seal breaks in the retina to prevent Retinal detachment
- Delimiting laser is done for peripheral retinal degenerations, tears/ holes in retinal periphery
