Hello doctor,What is HMD (hereditary macular degeneration) and what is the maximum possible impact of this disease in future on a person? Can this disease make one blind?
Hello, Welcome to Chat Doctor forum. HMD (hereditary macular degeneration) is a broad term given to a group of diseases that mainly affect the retina by deposition of some kind of material in between the retinal layers. These are genetic diseases. Though I have not seen anybody going completely blind with HMD, it can affect the visual acuity to a great extent. The visual loss starts gradually and can get severe in the next 15 to 20 years or so. The patient becomes disable up to the age of 45 years approximately. Right now, there is no intervention possible for this disease. For more information consult an eye care ophthalmologist online
