Myopic choroidal neovascularisation (growth of new blood vessels) is treated with anti-VEGF injections, the anti-VEGF injection reduces or stops the growth of new blood vessels.If a retinal tear is present they can use laser (retinopexy) or freezing (cryotherapy or cryopexy) to seal the tear and stop a retinal detachment from occurring. They are monitored to ensure further retinal complications do not occur. Retinal atrophy, lattice degeneration and lacquer cracks are not usually treated.The scarring causes the patient to experience a permanent blank spot in their central vision. A circular spot of scarring is left behind on the macula. ğoster Fuchs spot is when the new blood vessels and leakage in the central vision has dissipated.If you notice any of this you must see your optician or an ophthalmologist at your local eye hospital immediately. Patients may also experience grey or blank spots in their central vision. Wet Myopic macular degeneration occurs suddenly and will affect your colour vision, ability to see detail, cause straight edges to appear very wavy, cause difficulty in recognising faces and reading.The leakage of fluid can cause damage and swelling (oedema), neovascularisation can occur anywhere on the retina including your central vision, the macula (this is called wet myopic macular degeneration). As the new blood vessels are very weak they can leak easily. Ĝhoroidal Neovascularisation (CNV), are new blood vessels that have grown from the Choroid (layer under the retina) and passed between any breaks or tears in the retina.Untreated Glaucoma causes a patient to lose their peripheral vision over time. Patients with degenerative myopia should undergo intensive visual fields yearly. This causes a build up of fluid, as the drainage angle is impaired, the eye pressure begins to rise and causes damage to the optic nerves. Glaucoma the drainage angle of eye can be affected with degenerative myopia.Patients with degenerative myopia should undergo a dilated fundus (retina, nerve and macula) check yearly. If you experience this you must get to your local hospital eye service immediately. A retinal detachment would appear as a shadow or curtain in your vision. If the break occurs in the retina, fluid can leak behind the retina, this pushes the retina forward and eventually causes the retina to detach. An ophthalmologist may recommend treatment to avoid a future detachment. Patients with degenerative myopia that have lattice degeneration or retinal holes are at more risk of having a retina detachment. Thinning of the retina can also cause retinal holes and lattice degeneration (a type of thinning retina).ĝry myopic macular degeneration may affect your ability to see detail, cause straight edges to appear wavy, cause difficulty in reading. ![]() If retinal atrophy occurs at the macula (central vision) it may affect your ability to see detail and colour, this is known as dry myopic macular degeneration. These areas of your vision would appear patchy or blank. The areas of thinned retina may not function properly or at all. Retinal atrophy is the stretching & thinning of the retina this occurs as you become more short sighted and your eyeball becomes longer.Lacquer cracks are fine lines seen on the retina, they are caused by breaks in Bruch’s membrane (Bruch’s membrane is between the retina and choroid, at the back of the eyes), they are usually just monitored and are a warning sign that further complications could occur in the future.ğuch’s spots are the abnormal network of blood vessels in the macula region, which cause damage to the central vision.You would experience a loss of your central vision. Abnormal blood vessels can grow in the damaged areas under the macula, which can then leak fluid & cause scarring. Myopic Macular Degeneration, as the eyeball stretches the layers under the macula (central vision) become stressed and damaged.This will eventually cause distortion to your central vision and can lead to a macula hole or retinal detachment. Where the bulging at the back of the causes the layers of the central vision (macula) to split away from each other. Myopic foveoschisis (myopic traction maculopathy) is caused by Staphylomas.This can lead to loss of vision and sometimes blindness. Staphylomas is when the retina & sclera stretch and thin the back of the eyeball begins to bulge.Pathological myopia may cause the following eye conditions If your central vision is affected – difficulty in seeing fine detail, colour or grey or blank areas.ğrequent changes in your myopia or increases in your prescription. ![]()
