Acute Retinal Necrosis (ARN) is a serious
condition of the eye(s) / visual system that is thought to be due to a
viral infection.
As implied by its name, this condition:
- is "Acute",
that is, it may occur and develop quickly and be severe in extent.
- is "Retinal", that is, it affects the retina
of the eye/s.
- involves "Necrosis", which refers to the death of some or
all of the cells forming a particular tissue or organ.
Symptoms of Acute Retinal Necrosis (ARN) may therefore
include severe inflammation and damage to the tissues of the retina and
associated blood vessels. Haemorrhaging (bleeding) and retinal
detachment may also occur.
ARN may affect either or both eyes.
If both eyes are affected it may be called: Bilateral Acute Retinal
Necrosis (BARN).
