Understanding The Symptoms Of Vitiligo

Loss Of Color In The Retina

Eye choroid is a term used to describe a structure in an individual's eye that is abundantly vascularized. This structure provides the outer part of an individual's retina with blood flow. The eye choroid contains a choriocapillaris layer that borders the Bruch's membrane, Haller's layer, Sattler's layer, retinal pigment epithelium, and suprachoroidal layer. Patches of melanocytes and all of these layers that make up the choroid sit within an elastic and collagenous stroma. Melanocytes in the choroid are responsible for producing melanin to protect an individual's eye from the intraocular light reflections. The color that displays in an individual's iris is produced by the melanin in the uveal tract of their eye. Vitiligo in an individual can destroy pigment cells or melanocytes located in an individual's ciliary body, choroid, meninges, retinal pigment epithelium, and iris. When the melanocytes are destroyed in these parts of an individual's eye, they can experience a loss of color in their retina.
