Diabetic retinopathy (also known as diabetic eye disease) is a medical condition in which damage occurs to the retina due to diabetes.It is a leading cause of blindness in developed countries and one of the lead causes of sight loss in the world, even though there are many new therapies and improved treatments for helping people live with diabetes.
Retinal detachment should be considered if there were preceding flashes or floaters, or if there is a new visual field defect in one eye. [2] [3] If treated early enough, retinal tear and detachment can have a good outcome. [2]
Surgically correct retinal detachment by scleral buckle or pars plana vitrectomy. [1] Prior to surgery, oral or topical anti glaucoma drugs may be used to reduce IOP. [1] After surgical correction of the retinal detachment, the condition resolves, aqueous cells disappear and IOP normalizes. [3] The condition is not responsive to corticosteroid ...
The optic nerve contains axons of nerve cells that emerge from the retina, leave the eye at the optic disc, and go to the visual cortex where input from the eye is processed into vision. There are 1.2 million optic nerve fibers that derive from the retinal ganglion cells of the inner retina. [2] Damage to the optic nerve can have different causes:
The ischemic retina releases a variety of factors, the most important of which is vascular endothelial growth factor (VEGF). These factors stimulate the formation of new blood vessels (angiogenesis). These new vessels do not have the same characteristics as the blood vessels originally formed in the eye.
evidence that doing so has much impact. The results of economic analyses of obesity have often led to the conclusion that informational strategies aimed at targeting obesity have had and are likely to have only a limited effect (Eric A. Finkelstein et al. 2005, John G. Lynch Jr. and Gaul Zauberman 2006, and Kelli K. Garcia 2007).
[3] [4] Increased outflow or aqueous loss may occur following a glaucoma surgery, trauma, post-surgical wound leak from the eye, cyclodialysis cleft, tractional ciliary body detachment or retinal detachment. [3] Use of anti fibrosis drugs like mitomycin C during glaucoma surgery will increase the risk of hypotony maculopathy development. [2]
Blood leaks from the abnormal vessels into the back of the eye, leaving behind cholesterol deposits and damaging the retina. Coats' disease normally progresses slowly. At advanced stages, retinal detachment is likely to occur. Glaucoma, atrophy, and cataracts can also develop secondary to Coats' disease.
