Summary
Retinal oxygen saturation (SaO2 and SvO2) in Chinese adolescents is lower than in adults. Arterial oxygen saturation (SaO2) and arteriovenous difference (Sa-vO2) increase with age, while venular oxygen saturation (SvO2) increases with myopia.
Area of Science:
- Ophthalmology
- Retinal Physiology
- Chinese Adolescent Health
Background:
- Retinal oxygen saturation is a crucial indicator of ocular health.
- Normative data for retinal oxygen saturation in Chinese adolescents are lacking.
- Understanding these values is essential for diagnosing and managing various eye conditions.
Purpose of the Study:
- To establish normative values for retinal oxygen saturation in healthy Chinese adolescents.
- To investigate the relationship between retinal oxygen saturation and factors like age and refractive error.
Main Methods:
- Retinal oximetry was performed using the Oxymap T1 Retinal Oximeter.
- Arterial (SaO2) and venular (SvO2) oxygen saturation, and arteriovenous difference (Sa-vO2) were measured in 122 healthy participants aged 5-18 years.
- Data were analyzed to determine normative values and correlations.
Main Results:
- Mean SaO2 was 85.5±7.1%, SvO2 was 48.2±5.5%, and Sa-vO2 was 37.3±6.5%.
- Retinal oxygen saturation varied significantly across fundus quadrants, being lowest in the inferotemporal quadrant.
- SaO2 increased with older age and myopia; SvO2 increased with myopia; Sa-vO2 increased with age.
Conclusions:
- This study provides the first normative data for retinal oxygen saturation in Chinese adolescents.
- Adolescent retinal oxygen saturation values (SaO2 and SvO2) are lower than those reported for adults.
- Age and refractive error are significant factors influencing retinal oxygen saturation in this population.
