Retina

What is Retina?

Retina is the light-sensitive tissue lining the inner surface of the eye. It converts light into neural signals and sends them to the brain, enabling us to perceive visual images. This vital structure plays a crucial role in our ability to see, making regular eye care essential for maintaining optimal retinal health.

The central part of the retina, called the macula, is used for straight-ahead vision. It is crucial for tasks involving fine vision such as reading, recognizing faces and distinguishing things

Common Retinal Problems:

Diabetic Retinopathy
The retinal blood vessels bring blood into and take it out of the back of the eye. In diabetes, however, the vessels may leak, causing the retina to swell and malfunction. When the swelling involves the central area of the retina or the macula, vision may be affected. (This is known as diabetic macular edema.) Sometimes there is formation of new blood vessels in the retina due to uncontrolled diabetes which is called Proliferative Diabetic Retinopathy. Treatment for these conditions may involve Observation, Lasers, Intravitreal Injections or Vitreo- Retinal Surgery as per severity of the disease process

Retinal Vein Occlusion The vessels that drain the blood from the retina (retinal veins) can sometimes get blocked (retinal vein occlusion) in patients with diabetes or high blood pressure. A retinal vein occlusion can cause the retina to swell with fluid and blood, blurring central and peripheral vision. At other times, new blood vessels may grow (Proliferative Retinopathy) and cause pain as well as very high pressure inside the eye (Neovascular Glaucoma). Treatment may involve Observation, Intravitreal injections, Laser or Vitreo-Retinal and Glaucoma surgery based on the clinical and investigative findings

Age Related Macular Degeneration (AMD) With age, some people may develop changes in the macula (the central part of the retina responsible for central and near vision). The Dry type of AMD, is more common, which usually causes gradual vision loss. The more Severe or Wet type causes the macula to swell with fluid and blood. Symptoms of wet macular degeneration include painless, blurred and distorted vision.
The dry type of AMD can be observed closely, while the wet form requires Intravitreal injections and lasers

Retinal Breaks and Retinal Detachment Retinal tears or rips can occur as part of an aging phenomenon, or following an intraocular surgery or eye injury. They more commonly occur in High Myopia. When a retinal tear develops, patients often see cobweb-like floaters or light flashes. The vitreous can leak beneath the tear, lifting the retina away from its attachments. This is called a retinal detachment, which if left untreated can cause blindness. Often laser surgery around retinal tears before the fluid accumulates enables surgeons to weld the retina to the underlying eye wall, preventing the occurrence of Detachment. Once the retina detaches, surgery is indicated to reattach the detached retina.

Central Serous Chorioretinopathy (CSCR) Central Serous Chorioretinopathy consists of fluid accumulation (serous detachment) beneath the macula. It can cause reduction and distortion of vision, abnormal color vision, and central scotoma (blind spot). Although the vast majority of cases resolve on their own, laser photocoagulation is sometimes necessary for persistent lesions and in those patients who require early visual rehabilitation.

Retinopathy of Prematurity: The retina in preterm babies is not fully developed which may predispose to development of abnormal blood vessels. These abnormal blood vessels can cause internal bleeding and even retinal detachment. This is called Retinopathy of Prematurity (ROP). This condition results in low vision or blindness - both of which are irreversible. That is why prompt screening and management is advised in all preterms and low birth weight babies
