RETINITIS PIGMENTOSA

Blood is needed for survival of tissues and organs Ischemia (loss of blood supply) leads to degeneration of tissues organs. Coronary ischemia leads to Heart attack Peripheral ischemia leads to Gangrene Eye retinal ischemia leads to Blindness... Anterior chamber has lens and cornea for which treatment is well established Posterior chamber has Retina, which have 1.5 million sensor cells (Rods-Cones) ischemic disease leads to degeneration of Rods and cones in diseases like Retinitis Pigmentosa (RP), and Age related Macular degeneration (ARMD) Optic Atrophy etc. having no treatment (Retinitis Pigmentosa Book Ed. Heckenlively JR.'4)... In modern era Bypass Surgery revascularise these tissues but there are many such situation where direct revascularization is not feasible and surgeon feel helpless losing tissue and organ.
