There are many eye diseases affecting human beings, but macular degeneration is an eye problem which affects individuals usually aged forty years and above. There are many symptoms of macular degeneration. But, macular drusen is the main symptom which is experienced earlier by majority of the affected people.
Macular drusens are small yellow or whitish deposits which form on the eye. They are sometimes lipids or fatty compounds and calcium in the membrane of the retina. They affect the Bruch’s membrane which is a layer underneath the retina. Other layers of the retina which are sometimes affected are retinal pigment epithelium (RPE) and choroid layer. These layers are filled with blood vessels which may sometimes burst and develop as bleeding vessels in the eye. These three layers provide the rod and cone cells of the eye with nutrients and oxygen, and get rid of waste products in the cells. Any interference in this process of absorption and transportation in the cone and rod cells of the eye may damage the cells.
Due to the effects of macular drusen, age related macular degeneration (AMD) begins, varying with the different stages of development. And these stages or phases are classified and described below.
When early age related macular degeneration occur, one may experience several small drusen in the eye, hence this calls for immediate examinations and treatments, before it becomes severe. Therefore, proper education on the condition will help you in preventing the progression of the eye disease.
An individual at this stage will show signs of medium sized drusen and she may also experience some blurred spots in the central vision area of the eye. Therefore, seeing objects properly may require more light.
At the advanced macular degeneration stage, one will have large sized drusens. The photoreceptor cells will also be affected and lead to severe degeneration. You will also have a bigger and darker blurred spot in the central of the eye and vision problems will increase. For instance, it will be difficult to read or even recognize faces.
There are two types of macula drusens associated with macula degeneration. They are either soft drusens or hard drusens. Hard drusens are less harmful and are common to people aged 40 years and above. An individual with hard drusen may not even not even them. They are made of lipids and calcium. Soft drusens are pale yellow and may vary in size and shape. They may affect the membrane of the retina and cause it to separate with other layers. This may lead to complete vision loss and sometimes cause eye bleeding.
When you notice these symptoms, you should not ignore them, but visit a physician and get the immediate treatment.
