Age-related macular degeneration, or AMD, is an eye condition in which a person’s central vision gets blurred while the peripheral vision remains the same. It is a result of damage to the macula, or the sensitive part of the retina. Apart from age, other risk factors include genetics, race and smoking.
AMD can either be “dry” or “wet.” Clear View Vision Care, your provider of eye care needs in the area, discusses them further in today’s article.
Dry Type of AMD
Also known as the atrophic type of AMD, it is the most common, occurring in about 85% to 90% of all cases. Here, the affected retina slowly deteriorates due to the accumulation of yellow deposits under the macula called drusen. It results in the macula becoming thin and dry, losing its function to maintain central vision.
Patients with this condition may still have a good central vision, albeit with certain functional limitations. These include difficulty reading and limited vision in dim conditions. Undergoing regular eye exams can help manage dry AMD. Breaking the smoking habit and taking eye vitamins also works to stop its progression.
Wet Type of AMD
Also known as the exudative type of AMD, it is less common than the dry one at around 10% to 15% of all cases. It is a result of the growth of abnormal blood vessels under the retina and macula, which then bleed and leak fluid. The once flat macula bulges because of this, destroying central vision. Unlike dry AMD, the loss of vision can be severe and occur at a faster rate.
Patients with this condition may see dark spots in their central vision because of blood in the macula. Even so, there are cases where vision changes aren’t that noticeable. That said, undergoing eye examinations and regular treatment are necessary. Low-vision aids can also help in adapting to wet AMD.
With early diagnosis and proper treatment, you can delay the progression of AMD. You can turn to the eye doctors of Clear View Vision Care to assess your vision and detect potential risk factors for any eye-related condition. We also offer treatment options for dry eyes, ortho-k and vision therapy.
