Retinal migraine is a retinal disease often accompanied by migraine headache and typically affects only one eye. It is caused by ischaemia or vascular spasm in or behind the affected eye. The terms "retinal migraine" and "ocular migraine" are often confused with "visual migraine", which is a far-more-common symptom of vision loss, resulting ...
Pseudoexfoliation syndrome, often abbreviated as PEX [1] and sometimes as PES or PXS, is an aging-related systemic disease manifesting itself primarily in the eyes which is characterized by the accumulation of microscopic granular amyloid-like protein fibers. [2] Its cause is unknown, although there is speculation that there may be a genetic basis.
Specialty. Ophthalmology. Central serous chorioretinopathy ( CSC or CSCR ), also known as central serous retinopathy ( CSR ), is an eye disease that causes visual impairment, often temporary, usually in one eye. [1] [2] When the disorder is active it is characterized by leakage of fluid under the retina that has a propensity to accumulate under ...
Ophthalmology. Vogt–Koyanagi–Harada disease ( VKH) is a multisystem disease of presumed autoimmune cause that affects melanin -pigmented tissues. The most significant manifestation is bilateral, diffuse uveitis, which affects the eyes. [2] [3] VKH may variably also involve the inner ear, with effects on hearing, the skin, and the meninges ...
1:30,000 to 1:50,000. Leber's hereditary optic neuropathy ( LHON) is a mitochondrially inherited (transmitted from mother to offspring) degeneration of retinal ganglion cells (RGCs) and their axons that leads to an acute or subacute loss of central vision; it predominantly affects young adult males. LHON is transmitted only through the mother ...
Symptoms. The symptoms and signs associated with convergence insufficiency are related to prolonged, visually demanding, near-centered tasks. They may include, but are not limited to, diplopia (double vision), asthenopia (eye strain), transient blurred vision, difficulty sustaining near-visual function, abnormal fatigue, headache, and abnormal postural adaptation, among others.
Choroidal neovascularization ( CNV) is the creation of new blood vessels in the choroid layer of the eye. Choroidal neovascularization is a common cause of neovascular degenerative maculopathy (i.e. 'wet' macular degeneration) [1] commonly exacerbated by extreme myopia, malignant myopic degeneration, or age-related developments.
Frequency. ~20% [5] Dry eye syndrome, also known as keratoconjunctivitis sicca, is the condition of having dry eyes. [2] Symptoms include dryness in the eye, irritation, redness, discharge, blurred vision, and easily fatigued eyes. Symptoms range from mild and occasional to severe and continuous. [3]
