Uvea : A human eye is made up of three layers, the pigmented middle layer of the eye is known as uvea. It includes the iris, ciliary and choroid of the eye.
Retina : At the back of our eye lies a sensitive layer which is known as the retina, it is through the retina that one can see things when light fall.
Diabetes is a major cause of eye disease or blindness in the world today. It may lead to conditions like eye redness, young age cataract, pain in eyes, blurring of vision and so on. Uncontrolled diabetes leads to damage of the blood vessels of the eye, resulting in fluid accumulation in the retina, and generates fluid pressure on the optic nerves. This in turn stops the flow of oxygen and nutrients to the retina leading degeneration of the retina.
The symptoms of Diabetic Retinopathy are hard to detect. An ophthalmologist suggests thorough investigations before diagnosis based on their results the proper treatment is planned
Intravitreal injections of steroids are used to reduce abnormal growth of the blood vessels and to prevent leakage from them into the retina. These injections are also used before a surgery to reduce the bleeding factor during surgery.
It is one of the most common treatments for Diabetic Retinopathy. This treatment cannot retrieve the lost vision; it is used to safeguard the existing vision, so that no further damage is done to the retina. Here the eye surgeon uses laser to destroy the parts of the retina which have been damaged, or are deprived of oxygen and nutrients. It reduces the pressure of the blood vessels on the retina and controls fluid flow.. The procedures is done in multiple sittings and may take around three to four months for recovery , as the process works on regressing or reducing the swelling of the blood vessels to reduce pressure on the retina and optical nerves.
This procedure is used to avoid total loss of vision due to Vitreous hemorrhage (bleeding of blood vessels into the gel like center of the eye. Here the eye surgeon uses micro surgical tools and procedures to remove the blood and blood scar tissues from the vitreous.
Patients suffering from Diabetic Retinopathy can’t regain their lost vision, only their existing vision can be protected and treated. Proper control of diabetes can limit the complications of Diabetic Retinopathy. However research shows that vision loss from cataracts and bleeding in eyes can treat and regained.
Age Related Macular Degeneration– is damage of deterioration of the macula with progressive age. Macula is that part of the retina which allows clarity of vision. It is a common form of disorder found in the elderly, especially after the age of 65. AMD is of two types: Dry AMD and Wet AMD.
There is no treatment for loss of vision due to dry AMD. Although a good dietary plan and intake of nutrition supplements can slow the damage from ADM. It helps in flow of oxygen and nutrients in the chloroid to prevent deposit of drusen beneath the retina.
Treatment of wet AMD includes the flow of fluid in the retina and reversing the development of blood vessel growth in the eye. It also includes control of the cholesterol level and hypertension level to avoid further damage to the eye.
Retinal Detachment is that stage of eye damage when the retina separates from the back of the eye. This can cause partial or total eye vision.
A proper and timely check-up with your doctor is advised to manage your eye in the best way.
