The condition primarily affects the retina , the light-sensitive layer at the back of the eye , and sometimes the optic nerve , which transmits visual signals to the brain .
The blurred vision usually resolves within 10 weeks but individuals are often left with less vivid color vision, especially red, in the affected eye. [citation needed] A systemic intravenous treatment with corticosteroids may quicken the healing of the optic nerve, prevent complete loss of vision and delay the onset of other symptoms. [citation ...

A steroid regimen taken orally, often at low doses, is recommended as a first course of treatment. The low dose of steroids can help decrease inflammation, and as a result, lessens the visual impairment. In the event steroids are not effective, medicines may be administered via injections directly into the eye. One such treatment uses Ozurdex ...
The prognosis for CSR is generally excellent. While immediate vision loss may be as poor as 20/200 in the affected eye, clinically, over 90% of patients regain 20/25 vision or better within 45 days. [1] Once the fluid has resolved, either spontaneously or through treatment, distortion is reduced and visual acuity improves as the eye heals.
Vision can improve slowly after discontinuing ethambutol but rarely returns to baseline. Amiodarone is an antiarrhythmic medication commonly used for abnormal heart rhythms (atrial or ventricular tachyarrhythmias). Most patients on this medication get corneal epithelial deposits, but this medication has also been controversially associated with ...
A person with photic retinopathy may notice an impairment in their vision, for example a spot that does not go away after a reasonable recovery time, or blurring. They may also have eye pain or headaches. Vision impairment is usually in both eyes, but can be in just one. Impairment of a person with 20/20 vision usually ends up being about 20/40 ...
