Summary
Nearly half of pediatric cataract patients showed significant interocular axial length difference (IALD). This difference was more common in unilateral cases, where age at surgery and axial length predicted IALD.
Area of Science:
- Ophthalmology
- Pediatric Ophthalmology
- Biometry
Background:
- Pediatric cataracts require timely surgical intervention.
- Accurate axial length measurements are crucial for visual outcomes.
- Understanding interocular axial length difference (IALD) in pediatric cataract patients is important for surgical planning and management.
Purpose of the Study:
- To report the interocular axial length difference (IALD) between the operated eye and the fellow eye in pediatric cataract surgery patients.
- To analyze factors influencing IALD in this population.
Main Methods:
- Retrospective analysis of 171 pediatric eyes with cataracts.
- Descriptive statistics, analysis of covariance, and regression analysis were employed.
- Patient age at surgery ranged from 0.2 to 230.0 months.
Main Results:
- The mean IALD was 0.05 mm (SD ±1.15 mm), with absolute mean IALD of 0.76 mm (SD ±0.86 mm).
- 48.0% of subjects exhibited an IALD of ≥0.5 mm.
- IALD was more predictable in unilateral (24.0% with ≥0.5 mm shorter operated eye, 24.0% with ≥0.5 mm longer operated eye) than bilateral cases (P < 0.001).
- In unilateral cases, age at surgery (P = 0.04) and axial length (AL) of the operated eye (P < 0.001) correlated with IALD.
Conclusions:
- An IALD of ≥0.5 mm was observed in 48.0% of pediatric cataract patients.
- IALD occurred more frequently in unilateral than bilateral cataract cases.
- In unilateral pediatric cataracts, age at surgery and operated eye's AL can aid in predicting IALD.
