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.
Study Design
Arms and Interventions
Arm | Intervention/Treatment |
---|---|
Experimental: Normal subjects Normal subjects at banha university that are seeking regular ophthalmic check-up. |
Device: Multifocal electroretinogram (mf-ERG) by electroretinogram device
Measurement of mf-ERG parameters with 61 stimulus elements to asses amplitude of waves in nano volt/degree square (nv/deg2) and latency in millisecond (msec) as measured by electroretinogram device.

Outcome Measures
Primary Outcome Measures
- Amplitude of waves in nv/deg2 [immediately after mf-ERG diagnostic test for each eye.]
Measurement of the amplitude of N1 and P1 waves.
- Latency of waves in msec. [immediately after mf-ERG diagnostic test for each eye.]
Measurement of the latency of N1 and P1 waves.
Secondary Outcome Measures
- Difference between different age groups in mf-ERG readings. [immediately after mf-ERG diagnostic test for each eye.]
Statistical analysis for mf-ERG amplitude and latency in different age groups.
