BCEM, also referred to as conjunctival hypermelanosis, complexion-associated melanosis, or racial melanosis, is a non-cancerous lesion of the conjunctiva that is more commonly found in dark-skinned individuals (over 90% of lesions are found in black persons and around 5% in white persons). [1]
Periorbital hyperpigmentation, also known as hereditary dark circles, is characterized by darker skin around the eyes caused by the presence of additional melanin. It is an extremely common hereditary human characteristic and is frequently found on individuals with dark skin. Periorbital hyperpigmentation is most prevalent within the 16–25 ...
Acute posterior multifocal placoid pigment epitheliopathy (APMPPE) is an acquired inflammatory uveitis that belongs to the heterogenous group of white dot syndromes in which light-coloured (yellowish-white) lesions begin to form in the macular area of the retina.
Note pigment deposits in the mid periphery along with retinal atrophy. While the macula is preserved there is some loss of pigmentation around it. Specialty: Ophthalmology, Optometry: Symptoms: Trouble seeing at night, decreased peripheral vision [1] Usual onset: Childhood [1] Causes: Genetic [1] Diagnostic method: Eye examination [1] Treatment
In addition, many skin care ingredients can help in the form of eye creams. Caffeine is a potent vasoconstrictor that has been proven to improve the look of dark circles [16] by constricting, or tightening, the dilated vessels under eyes. Vitamin C can help brighten hyperpigmentation as well as thicken the dermal layer of skin which conceals ...
The pigment loss can be partial (injury to the skin) or complete (caused by vitiligo). It can be temporary (from tinea versicolor) or permanent (from albinism). [1] Most commonly, depigmentation of the skin is linked to people born with vitiligo, which produces differing areas of light and dark skin. Monobenzone also causes skin depigmentation.
Uveal melanoma is a type of eye cancer in the uvea of the eye. [4] It is traditionally classed as originating in the iris, choroid, and ciliary body, but can also be divided into class I (low metastatic risk) and class II (high metastatic risk). [4]
Ocular albinism type 1 (OA1) is the most common type of ocular albinism, with a prevalence rate of 1:50,000. [1] [2] It is an inheritable classical Mendelian type X-linked recessive disorder wherein the retinal pigment epithelium lacks pigment while hair and skin appear normal.
