Retina Association

Like a camera, the eye has a lens up front and a film at the back (retina). Behind your pupil, about two centimeters from the front, is your retina. A cup-shaped structure lies behind your retina. A signal is transmitted from the retina to the brain based on the ocular image. A central area of the retina, called the macula, is responsible for straight-ahead vision and direct line-of-sight perception.

The macula is crucial to tasks that require fine vision, including reading, recognizing faces, and differentiating objects. As the area surrounding the macula helps with mobility and in seeing from the corner of the eye, it is not good for fine work. The retina is connected to the brain through the optic nerve. In order to maintain the health of the retina and the optic nerve, blood vessels supply them with blood. The vitreous cavity is in front of the retina, and it is filled with a gel-like substance called the vitreous.

Serious vision problems can be caused by diseases of the retina, the vitreous, and the optic nerve. Fortunately, most of them can now be successfully treated with modern methods of diagnosis and treatment.

Prematurity-related retinopathy

Why should I be worried about a premature baby's eyes?

Premature babies do not have a fully developed retina, which lines the inside of the eye. An abnormal blood vessel can form in such a retina. They can cause internal bleeding and even retinal detachment. Prematurity-induced retinal degeneration (ROP). A person suffering from this condition will lose their vision or become blind – both are irreversible.

What are the ways to detect ROP?

Using eye drops, a trained ophthalmologist can detect ROP by dilating the pupil of the eye. The entire retina is scanned using an indirect ophthalmoscope in order to detect ROP and gauge the maturity of the retina.

Is a retinal examination necessary for all babies with ROP?

A baby with a birth weight below 1700 grams or a baby born under 35 weeks of pregnancy are most likely to have ROP.
Pre-term babies who have suffered problems after birth including lack of oxygen, infections, blood transfusions, breathing difficulties, etc., are also vulnerable.

Can my baby's eyes still be saved?

“Day-30” is the strategy to follow. Premature babies should undergo a retinal examination before “day-30” of their lives. It should be done earlier (at 2-3 weeks after birth) in babies who have low birth weights (*1200 grams).

How does ROP get treated?

Rop can be treated with either laser rays or freezing (Cryopexy). By stopping the growth of abnormal vessels, vision loss can be prevented.

What is the recommended frequency of retinal examinations?

ROP progresses in 7-14 days; therefore, it is necessary to follow the patient closely till the retina matures.

What is the best time to treat ROP?

When a severe case of ROP reaches a critical stage called Threshold ROP, vision loss is 50% or greater if left untreated after this. Time is crucial! In the post-treatment period As long as the child is treated in time, he or she should have reasonably good vision. All premature babies need regular eye examinations until they start school. Patients may need glasses or treatment for lazy eyes/crossed eyes, and sometimes, for cataract, glaucoma and retinal detachment.

Tips & Info

Laser Treatment of the Retina

Lasers emitted pure, high-intensity beams of light. With laser therapy, the laser light can be focused precisely onto the retina, selectively treating the desired area while leaving the surrounding tissues untouched. The absorbed energy creates a microscopic spot to destroy lesions or weld tissues together.

In most cases, laser surgery is painless; at most, it may cause temporary discomfort. Usually, this procedure is performed in the operating room while the patient is awake and comfortable. Patients with severe discomfort or children who cannot remain still during treatment may be anesthetized if they cannot tolerate the discomfort. The whole procedure takes 10 to 30 minutes.

Who needs laser treatment?

Among the eye conditions that lasers are commonly used to treat are:

Diabetic Retinopathy

The retinal blood vessels are like pipes, bringing blood into the eye and carrying it out. In diabetes, however, the vessels may leak, resulting in retinal swelling and impaired function. When the swelling affects the central area of the retina, vision may be impaired. affects the central area of the retina, vision may be impaired. occurs in the central part of the retina, vision may be impaired (this is called diabetic macular edema).

 

In order to prevent further vision loss, laser treatment can seal leaks in the eye. The retinal blood vessels of some patients may grow again, replacing those that have closed due to diabetes. (This condition is known as proliferative diabetic retinopathy.) Unlike the normal blood vessels, this new blood vessel bleeds inside the eye, resulting in reduced vision. These new vessels can often be regressed by laser treatment, thereby preventing severe vision loss.

Retinal Vein Occlusion

Sometimes, the small vessels that drain blood from the retina (retinal veins) become blocked (retinal vein occlusion). Diabetics and high blood pressure patients are more likely to develop this condition. The occlusion of a retinal vein can cause the retina to swell with fluid and blood, blurring central and peripheral vision. New blood vessels may also grow inside the eye, causing pain and high pressure (neovascular glaucoma).

In some cases, laser treatment can reduce this swelling or disappear the new blood vessels.

Macular Degeneration (AMD) as a result of aging

It is also possible for some people to suffer from changes in the macula, the part of the retina responsible for our central vision. Dry AMD results in gradual vision loss most of the time. With a severe or wet type of swelling, blood and fluid cause swelling in the macula. Blurred vision, painless swelling, and distorted vision are common symptoms of wet macular degeneration. In patients with wet AMD, laser surgery can sometimes prevent or delay vision loss. Wet AMD patients who have central vision problems must first undergo Visudyne injections before laser treatment, while those with off-center vision problems benefit from laser treatment. The treatment is called photodynamic therapy.

Retinal Breaks and Retinal Detachment

On the back of the eye, the retina is like a wallpaper. Occasionally, retinal tears or rips occur as a result of aging, or following an intraocular surgery or eye injury. The symptoms of a retinal tear are often cobweb-like floaters or light flashes. Vitreous, the liquid that normally fills the central portion of the eye, can leak beneath the tear, lifting it the retina away from the eye wall. The condition is known as a retinal detachment, which can lead to blindness if left untreated. Laser surgery around retinal tears before the fluid accumulates can weld the retina to the underlying eye wall. The procedure can prevent or limit retinal detachment.

Central Serous Chorioretinopathy (CSCR)

A central serous chorioretinopathy consists of one or more ‘blisters’ of fluid (sedentary detachment) beneath the macula. It can reduce or distort vision, result in abnormal color vision, create scotomas, and cause temporary hyperopia or far-sightedness. Despite the fact that most cases resolve on their own, laser photocoagulation may be necessary in persistent lesions or in those patients who need early visual rehabilitation.

Ocular Tumors

There are patients who have non-cancerous leaking vascular tumors that can cause the retina to swell and function improperly. Some of these tumors can be destroyed with laser surgery and the swelling can be reduced.

What are the signs that I need laser treatment?

In the case of retinal diseases, your eye will usually look and feel normal, even if there is bleeding and leakage in the back. You may also be able to see normally for a while even if you have potentially blinding eye problems.

The only way to find out whether you need laser surgery is to have careful, dilated retinal examinations at regular intervals, often followed by a special test (called fluorescein angiography if advised by the retinal specialist), to evaluate the eye’s circulation.

After laser surgery

There are virtually no restrictions following retinal laser surgery, but you would need to relax on the day of the treatment. Most patients find they can go back to their routine a day later. Invariably the doctor will advise you not to lift heavy weights for a few weeks. In some cases the doctor may advise patients to stay at home for several days. You will be required to come again for a follow-up examination in a couple of weeks up to a couple of months.

Most patients notice no changes in vision following their laser surgery, although there may be some temporary blurring for several weeks or even months. In addition, depending on the condition being treated, some patients may notice a permanent blind spot or decrease in peripheral and night vision.

Is one session of laser treatment enough?

The number of sessions required by a patient depends on the disease for which the laser treatment is done. It takes usually several weeks to months for surgeons to decide whether the treatment has been successful. Many patients require more than one session of treatment to control their problem and prevent further loss of vision.
