Choroideremia (/ k ɒ ˌ r ɔɪ d ɪ ˈ r iː m i ə /; CHM) is a rare, X-linked recessive form of hereditary retinal degeneration that affects roughly 1 in 50,000 males. The disease causes a gradual loss of vision, starting with childhood night blindness, followed by peripheral vision loss and progressing to loss of central vision later in life.
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.
Multiple evanescent white dot syndrome occurs mostly in females. Symptoms include a sudden loss of central vision, but patients eventually regain normal vision. The white dots are small and located in the posterior pole at the level of the retinal pigment epithelium. The white dots may disappear after the first few weeks of the disease.
It occurs equally between men and women with a male to female ratio of 1.2:1. Mean onset age is 27, but has been seen in people aged 16 to 40. [1] It is known to occur after or concurrently with a systemic infection (but not always), showing that it is related generally to an altered immune system. Recurrent episodes can happen, but are ...
Patients on amiodarone with new visual symptoms should be evaluated by an ophthalmologist. Tobacco exposure, most commonly through pipe and cigar smoking, can cause optic neuropathy. Middle-aged or elderly men are often affected and present with painless, slowly progressive, color distortion and visual loss in both eyes.
Symptoms include eye pain, eye redness, floaters and blurred vision, and ophthalmic examination may show dilated ciliary blood vessels and the presence of cells in the anterior chamber. Uveitis may arise spontaneously, have a genetic component, or be associated with an autoimmune disease or infection .
What is perhaps most striking about the 32 photographs that make up Jack Lueders-Booth’s new book, “Women Prisoner Polaroids,” is the intimacy that occupies each frame. Inmates wear their ...
Most frequent are symptoms due to conjunctival or corneal irritation: burning, photophobia, tearing, pain, and a gritty or sandy sensation.
