A retinal detachment is an eye condition involving separation of the retina from its attachments to the underlying tissue within the eye. Most retinal detachments are a result of a retinal break, hole, or tear.
This outer layer of the cornea is five to seven cells thick and measures about 50 microns — making it slightly less than 10 percent of the thickness of the entire cornea. Epithelial cells are constantly being produced and sloughed off in the tear layer of the surface of the eye.
The macula is located in the central part of the retina and has the highest concentration of cones. It is the area of the retina that is responsible for providing sharp central vision. The choroid is a layer of tissue that lies between the retina and the sclera. It is mostly made up of blood vessels. The choroid helps to nourish the retina.
Retinal detachment can occur if the anchoring of the outer layer of the retina to the eye wall is impaired. Since retinoschisis patients are more susceptible to retinal detachment, they should have regular examinations with an ophthalmologist.
