Effect of Intraocular Tamponade on Visual Perception
- Conditions
- Retinal DetachmentOptic NeuropathyGlaucoma
- 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.
