Serpiginous choroiditis, also known as geographic helicoid peripapillary choroidopathy (GHPC), is a rare, chronic, progressive, and recurrent bilateral inflammatory disease involving the retinal pigment epithelium (RPE), the choriocapillaries, and the choroid. [1] It affects adult men and women equally in the second to seventh decades of life. [2]

This leads to impaired vision. The best known representative of the pachychoroid disease spectrum, central serous chorioretinopathy, is the fourth most common cause of irreversible damage to the macula:. [1] [2] The term "pachychoroid" was first introduced in 2013 by David Warrow, Quan Hoang and K. Bailey Freund. [3]
The underlying etiology of APMPPE continues to cause debate. [5] [6] The term 'Pigment Epitheliopathy' was chosen by Gass [7] to reflect what he thought was the tissue most significantly affected. Van Buskirk et al., [8] and Deutman et al. [9] proposed choriocapillaris ischemia as the more likely primary etiology.
Punctate inner choroiditis (PIC) is an inflammatory choroiditis which occurs mainly in young women. Symptoms include blurred vision and scotomata.Yellow lesions are mainly present in the posterior pole and are between 100 and 300 micrometres in size.
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.
Siegrist streaks are a rare manifestation of hypertensive choroidopathy. They are described as hyper-pigmented flecks that are arranged in a linear fashion along the choroidal vessels of the eye . Although they are usually indicative of fibrinoid necrosis associated with malignant hypertension , Siegrist streaks also occur in patients with ...
Medical geology is an interdisciplinary scientific field studying the relationship between natural geological factors and their effects on human and animal health. [1] The Commission on Geological Sciences for Environmental Planning defines medical geology as "the science dealing with the influence of ordinary environmental factors on the geographical distribution of health problems in man and ...
