the separation of the *choroid from the *sclera of the eye as a result of leakage of fluid from the vessels of the choroid. It occurs when pressure inside the eyeball is very low, usually after trauma or intraocular surgery.
Separation of the retina from the outer layers at the back of the eye. Detachment may follow an eye injury but usually occurs spontaneously. It is usually preceded by a retinal tear, and is more common in highly myopic (shortsighted) people and in people who have had cataract surgery.
The detachment is painless. The first symptom is either bright flashes of light at the edge of the field of vision, accompanied by floaters, or a black “drape” obscuring vision.
Urgent treatment is required and usually involves surgical repair of the underlying tear. If the macula (site of central vision) has not been detached, the results can be excellent.... retinal detachment
the separation of the *vitreous humour from the underlying retina. This is a normal ageing process, but it is also more common in such conditions as diabetes and severe myopia. It can sometimes cause a tear in the retina and lead to *retinal detachment.... vitreous detachment
