Vitrectomy Surgery
The length of the operation varies from one to several hours depending on your condition In certain situations the ophthalmologist may do another surgical procedure at the same time such as repairing a detached retina or removing a cataract The ophthalmologist performs the operation while looking into your eye with a microscope Various miniature instruments are place into the eye through tiny incisions in the sclera white part of the eye In order to get best possible vision for you the ophthalmologist will do one or more of following Remove all cloudy vitreous Remove any scar tissue present attempting to return the retina to its normal position Remove any foreign object that might be in the eye Treat the eye with a laser to reduce future bleeding or to fix a tear in the retina Place an air or gas bubble in the eye to help the retina remain in its proper position the bubble will slowly disappear on its own Inject a special fluid that is later removed from the eye
Age Related Macular Degeneration ARMDMacular degeneration is a condition of the eye that is often related to aging It is commonly referred to as agerelated macular degeneration and is often abbreviated as AMDAge related macular degeneration is the most common cause of legal blindness in the geriatric population in the west and is probably more common in India than believed Dry ARMD causes thinning and atrophy of the macula with variable visual loss but is not amenable to any treatments as of now The age related eye diseases study had suggested that antixidants in combination with zinc could reduce the risk of progression in selected groups of these patients
Wet ARMD results from leakage or bleeding from choroidal neovascularisation and if untreated could lead to scarring and progressive visual loss Conventional laser therapy has been to be effective in the management of only a selected group of patients with extrafoveal disease Of the newer treatments available photodynamic therapy PDT and Transpupillary thermotherapy TTT appear most promising
Photodynamic therapy PDT with Visudyne Novartis
The light sensitive drug visudyne is injected into the patients bloodstream which accumulates in the abnormal new vessels in the eye This drug is activated by a nonthermal laser which closes the abnormal vessels without damaging the overlying sensory retina Studies have shown that PDT slows the progression and improves vision in some forms of the disease
Transpupillary Thermotherapy TTT
TTT is a cost effective alternative in the disease forms not eligible for PDT This is a low energy diode laser which directly closes the abnormal vessels with a small risk of damage to the overlying retina
Sub macular SurgerySub macular surgeries and macular translocation surgeries have been found to be effective in selected cases of advanced ARMD
