This results in blurred or distorted vision (metamorphopsia). A blurred or gray spot in the central visual field is common when the retina is detached. Reduced visual acuity may persist after the fluid has disappeared. [1] The disease is considered of unknown cause. It mostly affects white males in the age group 20 to 50 (male:female ratio 6:1 ...
Ocular myasthenia gravis (MG) is a disease of the neuromuscular junction resulting in hallmark variability in muscle weakness and fatigability. MG is an autoimmune disease where anomalous antibodies are produced against the naturally occurring acetylcholine receptors in voluntary muscles.
Diabetic Macular Edema (DME): is an eye disease specifically related to diabetes, occurring due to fluid build-up in the retina as a result of sustained high blood glucose levels. It can result in blurred vision and vision loss. [5] Eye floaters and spots: where visible cloud-like images appear to "float" in an individual's field of vision. [6]
Optic neuritis: Inflammation of the optic nerve from infection or multiple sclerosis may cause blurring of vision. [14] There may be pain while moving the eye or touching it through the eyelid. [14] Stroke or transient ischemic attack; Brain tumor; Toxocara: A parasitic roundworm that can cause blurred vision. [15] Bleeding into the eye
This is a partial list of human eye diseases and disorders. The World Health Organization (WHO) publishes a classification of known diseases and injuries, the International Statistical Classification of Diseases and Related Health Problems , or ICD-10.
There are many diseases known to cause ocular or visual changes. Diabetes , for example, is the leading cause of new cases of blindness in those aged 20–74, with ocular manifestations such as diabetic retinopathy and macular edema affecting up to 80% of those who have had the disease for 15 years or more.
Birdshot chorioretinopathy is thought to be an autoimmune disease. The disease has strong association with the human leukocyte antigen haplotype (HLA)-A29, which is the strongest association between a disease and HLA class I documented (>99% of patients are HLA-A29 positive by molecular testing and HLA-A29-negative cases are controversial [1]).
In many cases, only one eye is affected and the person may not be aware of the loss of color vision until the examiner asks them to cover the healthy eye. People may also engage in "eccentric viewing" using peripheral vision to compensate for central vision loss characteristic in genetic, toxic, or nutritional optic neuropathy.
