“…The current study showed that with early detection of ON, there is a good chance of improvement in visual acuity, with some cases reaching 6/6 or 6/5. A latest literature showed that VA can be improved in about 73% of patients to 6/12 or even better (Ambika et al, 2018), (Naumovska et al, 2018), (Kowsalya et al, 2023). However, despite treatment, contrast sensitivity still reduced, and in some cases, higher spatial frequencies were easily achieved, but low contrast frequencies still remain reduced, which is why patients still complain of photopsia's and transient loss.…”
