All FAQs

  • WHAT CAUSES VISION LOSS?

    Loss of vision is caused by two conditions:

    Diabetic Macular Edema: The weakened blood vessels leak and accumulate fluid in the retina which causes swelling and exudation in the macula of the retina causing loss of vision.

    Proliferative Diabetic Retinopathy (PDR): Due to the weakening of the blood vessels, new abnormal blood vessels grow resulting in bleeding in the vitreous. Vitreous is a jelly-like substance in front of the retina. A severe vision loss occurs due to the bleeding in the vitreous.

  • HOW LONG WILL THE CONDITION LAST?

    The condition may prevail for several years. It varies in its severity and can be quite unpredictable in its course. The main concern of the treatment is to thoroughly treat and monitor the inflammation so that minimal or no damage is caused to the eyes.

  • WHAT ARE THE CAUSES OF UVEA?

    Uvea can occur due to the following:
    1) Autoimmune and inflammatory conditions
    2) Viral, bacterial or parasitic infections
    3) Injury

  • WHAT IS THE PROGNOSIS?

    Anterior uvea usually has a good prognosis. There is always a risk of repeated attacks in the future.
    Posterior uvea involving central retina can impair visual loss permanently.
    Glaucoma due to uvea is difficult to treat and may cause permanent visual loss.
    Cataract surgery in uvea may have good results if adequate measures are taken.

  • WHAT ARE THE DIFFERENT TYPES OF UVEA?

    Anterior Uvea- affects the front of the eye, normally the iris (iritis) or the ciliary body (iridocyclitis). Iritis needs quite close monitoring because complications such as raised eye pressure and cataracts could occur.
    Intermediate Uvea- affects the middle of the eye, the ciliary body (cyclitis) or the pars plana (pars planitis). This could also cause floaters.
    Posterior Uvea- affects the back of the eye, the part of the uvea is called the choroid. An inflammation in the choroid is called choroiditis. The inflammation may also arise in, or affect, the retina (retinitis) or the blood vessels at the back of the eye (vasculitis).
