Numerous causes include virus infection. Injury from contact lenses can lead to keratitis. Eye with iritis showing ciliary flush. iritis [1] – together with the ciliary body and choroid, the iris makes up the uvea, part of the middle, pigmented, structures of the eye. Inflammation of this layer (uveitis) requires urgent control and is ...
Retinopathy is any damage to the retina of the eyes, which may cause vision impairment. [1] Retinopathy often refers to retinal vascular disease, or damage to the retina caused by abnormal blood flow. [2] Age-related macular degeneration is technically included under the umbrella term retinopathy but is often discussed as a separate entity.
