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 the central macula.
Photopsia. This is an approximation of the zig-zag visual of a scintillating scotoma as a migraine aura. It moves and vibrates, expanding and slowly fading away over the course of about 20 minutes. Migraine with aura, which includes photopsia 39% of the time, typically lasts 10 to 20 minutes and often is followed by a headache.
940 million / 13% (2015) [5] Visual or vision impairment ( VI or VIP) is the partial or total inability of visual perception. In the absence of treatment such as corrective eyewear, assistive devices, and medical treatment – visual impairment may cause the individual difficulties with normal daily tasks including reading and walking.

Visual Snow can appear at any time, but it commonly appears at birth, late teenage years, and early adulthood. Visual snow syndrome ( VSS) is an uncommon neurological condition in which the primary symptom is that affected individuals see persistent flickering white, black, transparent, or colored dots across the whole visual field.
Acute vision loss. A Snellen chart, which is frequently used for visual acuity testing. Acute visual loss is a rapid loss of the ability to see. It is caused by many ocular conditions like retinal detachment, glaucoma, macular degeneration, and giant cell arteritis, etc. Video explanation ( script) [1]
Ocular ischemic syndrome is the constellation of ocular signs and symptoms secondary to severe, chronic arterial hypoperfusion to the eye. Amaurosis fugax is a form of acute vision loss caused by reduced blood flow to the eye; it may be a warning sign of an impending stroke, as both stroke and retinal artery occlusion can be caused by thromboembolism due to atherosclerosis elsewhere in the ...
The ICD-10 established a set of diagnostic criteria for PCS in 1992. In order to meet these criteria, a patient has had a head injury "usually sufficiently severe to result in loss of consciousness" [33] [39] and then develop at least three of the eight symptoms marked with a check mark in the table at right under "ICD-10" within four weeks.
Contact lenses can provide a wider field of vision and fewer artifacts than even double aspheric lenses. Refractive surgery aims to permanently change the shape of the eye and thereby cure astigmatism. In Europe and Asia, astigmatism affects between 30% and 60% of adults. People of all ages can be affected by astigmatism.
