Macular degeneration means damage of the part of the eye called macula. The latter is a small area in the center of the retina that allows us to see details of the world around us clearly. Macular degeneration develops as part of the natural aging process of the body. It is characterized by a broad spectrum of clinical and pathological changes, such as pale yellow spots, known as drusen, disorders of the retinal pigment epithelium, choroidal neovascularization and macular degeneration distsiformena.
If you have macular degeneration, you may have symptoms of blurred vision, dark spots in the center of vision, inability to see either near, or far. Some activities such as threading a thread, reading, writing, drawing and others may be highly difficult or even impossible.
Forms of macular degeneration:
- Disease manifestations are grouped into two forms: non-exudative (dry) and exudative (wet or neovascular).
- Drusen are characteristic changes of the dry form, while neovascularization is typical for the wet form. Distsiformenata macular degeneration represents the fibrotic stage of the neovascular form.
- The dry form of macular degeneration is more common and affects 90% of the people having this disease. Vision loss occurs for a longer period of time than in the wet form. Neovascular form occurs in 10% of patients. Vision loss may be greater but occurs in a shorter period of time. Pathologically increased blood vessels leak fluid or blood, causing blurred vision, dark spots and other complaints.
Methods of Treatment
- Treatment of the dry form of macular degeneration. Treatment with antioxidants and zinc may delay the progression of early stages of the dry form of macular degeneration. There is no known treatment which can prevent loss of vision in the advanced stages of this form of macular degeneration.
- Treatment of the wet form of macular degeneration: laser photocoagulation Photodynamic therapy with Visudyne Intravitreal administration of drugs directed against VEGF (vascular endothelial growth factor) It should be noted that none of these methods can completely cure the disease and it may progress despite treatment.
Regular check-ups with your ophthalmologist are further required.
