The bubble of gas will block the vision while it's present, but it slowly disappears over a period of about 6 to 8 weeks, depending on the type of gas used. The eye is then filled with a temporary gas bubble, which presses the hole flat onto the back of the eye to help it seal. Small incisions are made in the white of the eye and very fine instruments are inserted.įirst, the vitreous jelly is removed (vitrectomy) and then a very delicate layer (the inner limiting membrane) is carefully peeled off the surface of the retina around the hole to release the forces that keep the hole open. Macular hole surgery is a form of keyhole surgery performed under a microscope. If the ocriplasmin injection fails to close the macular hole, vitrectomy surgery may be suggested to close the macular hole and improve the vision. You should not drive or use any tools or machines until it's back to normal. Your vision may be blurry immediately after the injection. double vision, headaches, or you are feeling or being sick.Surgery is usually needed to correct macular hole enlargement or retinal detachment. temporary discomfort, redness, dryness or itchingĪ small number of people may develop more severe side effects, such as a noticeable loss of vision, enlargement of the macular hole or retinal detachment.Ocriplasmin can cause some mild side effects, which usually go away, such as: You'll also be given eye drops to dilate your pupil so the ophthalmologist can see the back of your eye.Īn ocriplasmin injection is usually only available in the early stages – while the macular hole is less than 400 micrometres wide – but causing severe symptoms. The injection takes a few seconds and you'll be given local anaesthetic, as eye drops or an injection, so you won't feel any pain. The injection helps the vitreous jelly inside your eye to separate from the back of the eye and allows the macular hole to close. If a macular hole is caused by vitreomacular traction, it may be possible to treat it with an injection of ocriplasmin, also called Jetrea, into the eye. ![]() However, a second operation can still be successful in closing the hole. In a minority of patients, the hole does not close despite surgery, and the central vision can continue to deteriorate. If the hole has been present for a year or longer, the success rate will be lower.Įven if surgery does not close the hole, your vision will usually at least become stable, and you may find you have less vision distortion. The operation is successful in closing the hole in around 9 out of 10 people who've had the hole for less than 6 months. What is the treatment and how successful is it? Vitrectomy surgeryĪ macular hole can often be repaired using an operation called a vitrectomy. Sometimes the hole may close and heal by itself, so your ophthalmologist may want to monitor it before recommending treatment. Relatively early treatment (within months) may give a better outcome in terms of improvement in vision. If you do have a macular hole and you don't seek help, your central vision will probably get gradually worse. You'll probably be referred to a specialist in eye conditions (ophthalmologist). If you have blurred or distorted vision, or there's a black spot in the centre of your vision, see your GP or optician as soon as possible. persistent swelling of the central retina (cystoid macular oedema).being slightly long-sighted (hyperopic).retinal detachment – when the retina begins to pull away from the blood vessels that supply it with oxygen and nutrients.If some of the vitreous jelly remains attached, it can lead to a macular hole. As you get older, the vitreous jelly in the middle of your eye starts to pull away from the retina and macula at the back of the eye. One possible risk factor is a condition called vitreomacular traction. They most often affect people aged 60 to 80 and are more common in women than men. The vast majority of cases have no obvious cause. Your vision will never completely return to normal, but it's usually improved by having surgery. This is often successful, but you need to be aware of the possible complications of treatment. Surgery is usually needed to repair the hole. You won't feel any pain and the condition doesn't lead to a total loss of sight. Straight lines may look wavy or bowed, and you may have trouble reading small print.Īfter a while, you may see a small black patch or a "missing patch" in the centre of your vision. In the early stages, a macular hole can cause blurred and distorted vision. In the centre is the macula – the part responsible for central and fine-detail vision needed for tasks such as reading. The retina is the light-sensitive film at the back of the eye. A macular hole is a small gap that opens at the centre of the retina, in an area called the macula. ![]()
