Summary
This study establishes normative values for focal electroretinography (fERG) in young adults using International Society for Clinical Electrophysiology of Vision guidelines. Faster latencies were observed with 42 Hz stimuli compared to 31.25 Hz stimuli.
Area of Science:
- Ophthalmology
- Neuroscience
- Physiology
Context:
- Focal electroretinography (fERG) is crucial for assessing macular function.
- Establishing normative data is essential for interpreting clinical fERG results.
- Previous studies may lack standardization or focus on specific age groups.
Purpose:
- To determine normative values for focal electroretinography (fERG) in healthy young adults.
- To adhere to the standard protocol recommended by the International Society for Clinical Electrophysiology of Vision (ISCEV).
- To provide a reference dataset for clinical and research applications.
Summary:
- Thirty-three healthy young adults underwent fERG testing using ISCEV-recommended protocols with 42 Hz and 31.25 Hz flicker stimuli.
- Amplitude and latency parameters were analyzed using discrete Fourier transformation.
- Normative values, including medians, percentiles, minimums, and maximums, were calculated for both frequencies.
Impact:
- This study provides essential normative data for fERG in young adults.
- The findings aid in the accurate diagnosis and monitoring of retinal disorders.
- Standardized protocols ensure comparability of fERG results across different centers and studies.
