According to the research highlights of the July 2008 issue on Opthalmology, the Ophthalmologists of America are continuing to develop treatments for Glucoma. The July ssue contains a large study of outcomes of incisional surgeries, used to reduce the pressure inside the eye of the Medicare patients.
Glucoma is a disease by which maximum number of people throughout the world gets blind. This happens due to the damage of the disc of the eye's optic nerve, which compromise the transmission of images to the brain and thus leads to blindness if not treated properly.
The records of 14,491 Medicare beneficiaries were diagnosed with glaucoma who received one of three incisional surgeries — primary trabeculectomy (PT), trabeculectomy in presence of scarring from previous ocular surgery or trauma (TS), or implantation of a glaucoma drainage device (GDD) — between 1994 and 2003 by Frank A. Sloan, PhD, and colleagues.
All the three surgeries are designed to improve the drainage of fluid from the eye to reduce IOP. In trabeculectomy (both PT and TS), a small portion of the trabecular meshwork is removed to increase fluid flow, and in GDD a tiny implanted shunt is used to bypass the trabecular meshwork and redirect fluid flow. These incisional techniques have benefited millions of glaucoma patients who otherwise might be blind or have very low vision.
The study found that, although adverse outcomes were uncommon for all three surgeries, rates of severe outcomes, less severe outcomes, and progression to low vision or blindness were higher for persons who received GDD than for those who received PT or TS.
Concluding that with continued treatment, doctors can give hope to their patients having end-stage Glucoma, as said by the M.D Dr. Jason W. Much who lead the study.
