Registration Number
NCT05543018
Lead Sponsor
Benha University
Brief Summary

Intraocular tamponade used in vitrectomy operations may affects retinal function in various mechanisms.

Detailed Description

Various intraocular tamponade are being used in vitrectomy operations as gases, fluids and silicon oil. The effects of these intraocular tamponade may affects the final visual outcome of the surgery.
