The impact of dry eye disease on retinal image quality in children
Insights
Pediatric dry eye disease (DED) significantly impacts visual quality due to increased ocular light scatter. Double-pass technology reveals that higher DED severity correlates with poorer visual function in children.
Area of Science:
- Ophthalmology
- Pediatric Eye Care
- Visual Optics
Background:
- Dry eye disease (DED) is a growing concern in pediatric populations, leading to increased eye morbidity.
- Understanding the impact of DED severity on visual function in children is crucial for effective management.
Purpose of the Study:
- To evaluate the effect of DED severity on visual quality in children using double-pass technology.
- To analyze dynamic changes in ocular light scatter and their correlation with DED severity.
Main Methods:
- A cross-sectional study involving three groups: mild DED, moderate DED, and healthy controls.
- Assessment included Schirmer I test, tear film break-up time (BUT), OSDI questionnaires, and double-pass optical quality analysis (MTF cutoff, Strehl ratio, OSI, OQAS-II).
- Dynamic ocular scatter index (OSI) post-blinking and tear film OSI were recorded.
Main Results:
- Significant differences in optical quality parameters (MTF cutoff, Strehl ratio, OSI, OQAS-II) were found across DED severity groups (P < 0.05).
- Increased DED severity led to higher tear film mean OSI and decreased modulation transfer function cutoff, Strehl ratio, and OQAS-II values.
- Optical quality parameters correlated with BUT, but not with age, sex, or Schirmer I test results.
Conclusions:
- Double-pass technology provides an objective measure of visual quality in pediatric DED.
- Tear film scattering significantly degrades retinal imaging and overall visual quality in children with DED.
Background And Objectives:
Dry eye disease (DED) is increasingly prevalent, resultinginhigher morbidityamong children. This study evaluates the impact of DED severity on visual quality using double-pass technology, focusing on dynamic observation of the ocular light scatter in pediatric DED cases.
Method:
In this non-interventional, cross-sectional study, a mild DED group (37 cases, 37 eyes), a moderate DED group (40 cases, 40 eyes), and a control group of healthy children (35 cases, 35 eyes) were examined. Measurements included the Schirmer I test, tear film break-up time (BUT), and vision-related quality of life assessments using the Modified Ocular Surface Disease Index (OSDI) questionnaires. Participants underwent visual quality analysis using double-pass technology, which measured the modulation transfer function cut-off frequency value, Strehl ratio, objective scatter index (OSI), and OQAS-II value (OQAS-II value 100%, OQAS-II value 20%, and OQAS-II value 9%) under natural conditions. Additionally, dynamic changes in OSI post-blinking, Tear film mean-OSI , and the corresponding standard deviation OSI were recorded.
Results:
Statistically significant differences were observed among the groups in modulation transfer function cutoff, Strehl ratio, OSI, OQAS-II value 100 %, OQAs-II value 20 %, OQAs-II value 9 %, tear film mean OSI, and standard deviation OSI (P < 0.05). As DED severity increased, tear film mean OSI significantly rose, while modulation transfer function cutoff, strehl ratio, OQAS-II value 100 %, OQAS-II value 20 %, OQAS-II value 9 % notably declined. All optical quality parameters were correlated with BUT, with no association observed with age, sex, or Schirmer I test.
Conclusion:
Dual-channel technology objectively assesses visual quality in pediatric DED, demonstrating that tear film scattering significantly affects retinal imaging and visual quality in children with DED.
