Retinal Conditions

Ein Tal operates a unique specialist center for retinal conditions that is among the leaders in its field. The center is staffed by the finest retinal specialists and provides advanced treatment from consultation and diagnosis through special tests and imaging such as OCT, retinal laser treatments, intraocular injections, and a wide range of retinal surgeries, including advanced vitrectomy.


What is the retina and what does it do?

The retina is a delicate tissue that covers the inside of the eyeball. It absorbs the rays of light that reach the eye, and converts them into electrical signals that are transmitted to the brain through the optic nerve.

In order to achieve normal vision, the retina must be healthy and close to the wall of the eye. A variety of retinal diseases can impair the retina's function and health:

Age-related macular degeneration (AMD), retinal lesions due to diabetes, vascular blockages in the retina, macular edema, vitreous hemorrhage, epiretinal membrane, macular hole, retinal tears, and retinal detachments.


Laser Treatments for Retinal Diseases

Several retinal conditions can be treated with the help of laser devices:

  • Retinal tears
  • Growth of abnormal blood vessels, found in diabetes patients
  • Vascular blockages in the retina

Treatment is performed in a laser treatment room under local anesthesia. The laser is focused on different areas of the retina, in accordance with the relevant eye condition.


Intraocular Injections

Some retinal diseases that can be treated by injecting certain substances into the vitreous body within the eye. These substances can be divided into two groups:

One group is known as anti-VEGF, which is designed to prevent vascular growth and reduce leakage from small blood vessels around the macula. The three drugs contained in this group are Avastin, Lucentis and Eylea.

The second group of substances consists of steroids.


AMD, age-related macular degeneration, is the primary cause of severe vision impairment and blindness. Symptoms of this disease include blurred or patchy vision, gaps in the central visual field, and visual distortion. The only treatment for AMD is a series of anti-VEGF injections, among others, into the vitreous.

Diabetes affects the functioning of small blood vessels in the retina, causing leakage into the macula, edema, and loss of vision. The anti-VEGF substances and steroids injected into the eye reduce leakage from the blood vessels. The edema is absorbed and vision improves.


Retinal Surgeries – Vitrectomy

These surgeries are performed under local anesthesia. Their goal is to remove the vitreous body that fills the eye cavity. In the event of other eye conditions, additional procedures are added.

Vitrectomy is performed for the following conditions:


Vitreous Hemorrhage 
Various diseases can cause bleeding in the vitreous cavity, which results in an immediate loss of vision. Vitrectomy removes the blood from the vitreous and the patient's vision returns to normal.


Epiretinal Membrane 
A membrane that develops and grows across the retina in the central area of ​​the eye (macula) and may cause visual disturbances. In addition to the vitrectomy, the membrane is peeled off the surface of the retina.


Macular Hole
A small hole that develops in the center of the retina. This central vision area is called the macula, and it is responsible for visual acuity. In addition to the vitrectomy, the membrane is peeled off the surface of the retina and gas is injected.


Retinal Detachment 
A condition in which the retina disconnects from the wall of the eye. Retinal detachment results in vision loss. In addition to the vitrectomy, laser therapy is performed around tears and gas is injected that remains in the eye for up to two months after the operation. Silicone oil may also be injected into the eye cavity, and this requires additional surgery to remove the oil after a few months.
