How I do it How I do it ……

-- Systemic control is every thing !!!Systemic control is every thing !!!

-- Fundus florescein angiography ( wide field ?? ) + OCT Fundus florescein angiography ( wide field ?? ) + OCT Laser / Surgery ?Laser / Surgery ?

- ANTI VEGF ( prevents bleading / macular edema )

- Focal laser / modified grid laser phocoagulation

- Panretinal photocoagulation ( until extrem far periphery )

- Steroidal implant

- … and waiting for the next big thing !!!
