Multifocal Electroretinogram in Normal Egyptian Population

Not Applicable

• Conditions: Retinal Disease; Healthy Population
• Interventions: Device: Multifocal electroretinogram (mf-ERG) by electroretinogram device

• Registration Number: NCT05323032
• Lead Sponsor: Benha University

Brief Summary

Studying normal subjects to create unique normal database for multifocal electroretinogram (mf-ERG) in specific population.

Detailed Description

Normal parameters for electroretinogram (ERG) is important in studying specific population, studying normal subjects is important to create specific normal database for each population. This will help in accurate differentiation for various ocular diseases and in research trials.
