Hello,
Waiting for self recovery is the only option in this kind of 6th nerve palsy, and it recovers mostly if he keeps his
sugar levels under control. Some amount of diplopia might remain , which can be corrected by other methods. For his eye pricking use lubricant eyedrops available over the counter. (Refresh tears, lubrex justears ontears etc)'
Next Steps
wait for one more month and keep his
sugar levels under control, meantime you can do online consultation
