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 establishedPosterior 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. for which world has no treatment (Retinitis Pigmentosa Book Ed. Heckenlively JR.’4)
Though in modern era Bypass Surgery is used to revascularise these tissues. But there are many such situation where direct revascularization is not feasible and surgeon feel helpless losing tissue and organ. Eye is a such organ,
Retinal artery being intracranial is not assessable for bypass. . While all attempts are done to revascularise retina by newer viteroretinal surgical techniques (G.Paymen) and, every day claim of achieving success by new techniques are in-vain as none has long term good results and has lot of complication
RP patients are generally confused with these claims based on results of few cases, of short duration. Our technique of Omental transplant is based on our 25 yrs. experience of limb revascularisation with omentum and with published experimental study, that intact omentum can be transplanted in eye safely, with evidence of developing bypass between omental and retinal vessels(6), we modified Agarwal technique(7) of Pedicle Omental transplantation to eye by which stomach vessel supplies eye (retinal bypass surgery).
published in scientific journals and chapter in Retinal degeneration book. and have follow up of over 250 cases for 10 yrs
