There are two forms of AMD: dry AMD, also called atrophic, is the less serious and more frequent form. It evolves slowly over several years. All age-related macular degeneration begins in the dry form before progressing in about 10% to 15% of patients to the wet form. Wet AMD, also called exudative or neovascular, is therefore an exacerbation of the dry form. It is characterized by the formation of new blood vessels in the choroid, under the retina. Fluid build-up causes vision loss faster than the dry form. The wet form can lead to complete loss of central vision.
No one is safe from age-related macular degeneration (AMD), but there are factors, some controllable and others not, that increase the risk of AMD. Some uncontrollable risk factors include age, family history, and Caucasian race. On the other hand, lifestyle habits play an important role, smoking being one of the main risk factors. Do not neglect a healthy diet rich in omega-3 (nuts, cold water fish, flaxseed and rapeseed oil), as well as physical activity and weight control. It is also important to control blood pressure and protect your eyes from UV rays.
To date, there is no cure for atrophic AMD.
In some cases, vitamin supplements in a specific formulation called “AREDS” can reduce the risk of vision loss and progression.
The treatment of wet AMD is currently based on “anti-VEGF” drugs of which Lucentis® (ranibizumab) and Eylea® (aflibercept) are the most widely used. These drugs help stabilize the vision of the vast majority of patients treated, and even improve visual acuity. Giving these drugs directly into the eye has the advantage of very effective local action while minimizing systemic side effects. The intravitreal injection is done on an outpatient basis after applying anesthetic drops and only lasts a few seconds. The medicine is injected with a very fine needle through the sclera (white of the eye). This injection is safe for nearby eye structures.
While these injections can stabilize or even reverse the disease, they cannot cure it permanently. They must therefore be repeated often.
Retinal detachment is a potentially dangerous condition. In general, people of middle or advanced age are affected; more myopic. Most often, retinal detachment is caused by a tear in the retina, but it can also occur after a blow to the eye or have other, rarer causes. If not treated quickly, retinal detachment can cause vision loss or even loss.
The sudden appearance of dark spots in the visual field (flying flies or soot rain), flashes of light not provoked by an obvious cause or a dark shadow on the periphery of the field of vision can announce a detachment of the retina. A decline in vision is a later sign. From the outside a protruding retina is not visible and the affected eye is neither red nor painful.
