The longer it is left the less likely treatment will succeed so it is important to detect macular holes early. If left untreated, vision will usually deteriorate, so that you may only be able to read the top letter of an eye chart, or worse. Peripheral vision is unaffected and it doesn’t lead to complete blindness. How is vision affected?Ī macular hole affects central vision. Sudden appearance of flashing lights, floaters (specks or flecks that float across your vision) or fading vision could indicate a retinal detachment – in this case you should seek urgent medical help. Late symptoms include gaps or the loss of the most central vision. In the early stage there may be a slight distortion or blurred vision, straight lines may appear wavy and reading becomes difficult. This defect, unfortunately, is usually located at the centre of the macula which is responsible for the detailed visual function, where even a small abnormality can have a large impact on vision. However in certain cases, the vitreous humour is abnormally adherent to the surface of the retina, meaning abnormal traction - or pulling - can occur as the jelly becomes detached and pulls off a bit of the retina with it, leaving a circular defect in the retina layer. This process, called posterior vitreous detachment or PVD, normally occurs in most people as we get older. But as we get older, it becomes weaker and shrinks, detaching from the surface of the retina. The jelly usually fills the eye fully and is in contact with the retina surface. The occurrence of macular holes is thought to be due to abnormal adhesion and traction on the surface of the retina by the jelly or vitreous humour that normally fills the cavity of the eyeball. Macular holes occur in about 3 in 1,000 people over the age of 55. If the macula is damaged it is difficult to drive, watch TV, read or recognise faces. There is no risk of retinal infection, and the patient heals very quickly.A macular hole is a small defect in the retinal layer that develops at the centre of the macula. The recovery ratio is excellent for laser/Cryopexy procedure, as it doesn’t involve incisions or cuts around the retina. Therefore, you must follow your eye doctor’s advice and take prescribed medicines for a speedy recovery.Īlthough laser eye treatment is often painless, some patients complain of experiencing a mild “electric shock-like” feeling during the process. After the treatment is complete, your eyes may appear red for a few days. The damaged hole is secured to the inside of the eyeball to seal the hole. Cryopexy is performed under local anesthesia for patient comfort during the treatment. This procedure uses a cryoprobe to freeze the tissues around the retinal tear. For the first few hours post-treatment, you may experience blurred vision. The laser photocoagulation is a painless and quick procedure and is mostly performed on an outpatient basis. Then the surgeon will use the laser machine and with the help of the special retina laser seal the retina around the retinal holes and tears. The eye surgeon will apply anesthetic drops in the eyes for a painless treatment. In this procedure, an ophthalmologist will put eye drops to dilate your pupil. Your retina specialist will first examine your eye condition and then suggest one of the following retina treatments: The best method to prevent retinal detachment is to seal the tiny holes in the retina. What are the treatment options for a retinal break? If you are experiencing floaters (black, enlarged spots) in your vision, it is a good idea to get your retinal evaluation done by a good retina eye doctor. Some retinal detachments don’t need treatment, but most require treatment to prevent complete blindness. The initial symptoms of retinal detachment can be floaters and flashes of light around the eyes. The retinal separation or retinal detachment may not cause vision loss immediately, but eventually. In rare cases, the vitreous gel (gel present in the eyes) can cause a retinal tear formation when it detaches from its attachments on the retina.įormation of retinal tears and holes can predispose to retinal detachment if and when the fluid inside the cavity o the eye passes through the hole under the retina and ends up detaching it in the process. This retinal break is a tiny hole that usually develops in the peripheral part of the retina. In some patients, the retinal tissue start thinning and breaking down overtime at certain locations. Its major role is to help in vision generation by sending light signals to the brain. The retina refers to the eye’s inner lining, a part of the eye that contains light-sensitive tissues.
