|Title||What happens to the contralateral eye in optic nerve sheath fenestration (ONSF)?|
|Submitted by||Reena Kumari|
|Review Result||rapid fire presentation|
The circulation of CSF between the brain and the optic nerve is considered to be a 3-compartment system. ONSF is considered to work by decompression of the subarachnoid space leading to the filtration of the CSF around the optic nerve. It is also considered to cause scarring in the peri optic nerve sheath preventing consequent CSF accumulation and further risk of visual loss.
Patient were identified from the hospital database using the coding system for ONSF
• Total 38 patients were identified. 5 patients were excluded due to enough follow up data due to a combination of factors
From our case review we can say that there can be improvement in the visual acuity and visual field in our group of patients. In view of this result we should wait to see for a atleast a short time until the vision and visual fields can be reliably assessed for worsening/progression or improvement before embarking on contralateral side surgery.
