AMD - Age Related Macular Degeneration
AMD effects the sharp, central vision that allows us to see objects straight ahead. It is a common eye condition that tends to effect the population over 50 years old. With AMD is can progress slow or it can be progressively faster. The typical first symptom is a blurred or blank spot in your vision.
There are 3 stages of AMD -
There is early, intermediate and late stages and it is possible to have symptoms in one eye or be in different stages for each eye. The early and intermediate stages are diagnosed by the medium to large size drusens, the pigment will change in the retina and there may be vision loss. In the late stage there are multiple issues besides the drusen there is macular damage, athrophy or dry AMD, or neovascular or wet AMD.
Diabetic eye disease - Diabetic Retinopathy
Is a group of eye problems that may include Cataracts and Glaucoma that people with diabetes may face as a complication which can cause severe vision loss or even blindness.
There are 4 stages of Retinopathy-
Mild, Moderate and Severe Nonproliferative. This starts with swelling in the retinal blood vessels progressing to blockage of the blood supply which triggers the body to create new blood vessels. When this happens, it has reached stage 4, proliferative retinopathy. In this advanced stage the blood vessels grow in the clear surface, vitreous gel that can cause bleeding due to their fragile state. This can result in sever vision loss or blindness.
A lifting or pulling of the retina which is the light sensitive layer of tissue that lines the inside of the eye and sends messages through the optic nerve to the brain which can cause permanent vision loss.
There are 3 types of retinal detachment-
Tractional - This is a less common type of retinal detachment which is caused by scar tissue Exudative - This type is when fluid leaks under the retina caused by retina disease, trauma or an inflammatory disorder. Rhegmatogenous - This type is most common where there is a tear or break which causes fluid under the retina and produces separation. Symptoms are floaters, cobwebs or flashes of light. Retinal detachments are a medical emergency.
Uveitis Eye Disease
Uveitis can either be acute or chronic and caused by an inflammatory response in your body from toxins, bruising, infections or the autoimmune disease that can cause increased floaters, pain, decreased vision and light sensitivity.
Uveitis is classified by the area the eye is effected.
Anterior uveitis - occurs in the front of the eye, it is most common and normally affects the young and middle aged. It may occur in a healthy person but it is also seen with rheumatologic, skin, gastrointestinal, lung and infectious diseases.
Intermediate uveitis normally in young adults and seen connected to rheumatologic, skin, gastrointestinal, lung and infectious diseases.
Posterior uveitis is the least common and often called choroditis or chorioretinitis linked to many infectious and non-infectious causes.
Pan-uveitis affected by inflammation where Behcet’s disease is one of the most well-known forms.
