N2 - Objective: This study aimed to evaluate the ability of a digital fundus camera to observe the development of the anterior chamber angle (ACA) in premature infants. Methods: Forty-eight eyes of preterm infants (n=48) were examined by a digital fundus camera to observe the development of the ACA. ACA grading was performed based on the visualization of the anterior chamber structures according to the Scheie Angle Depth Evaluating System. Results: ACA images from all 48 infants were successfully acquired using RetCam3. The corrected gestational age ranged from 30 weeks to 49 weeks, which covered the period from 2 months preterm to >2 months post-term. As the corrected gestational age increased, the corrected gestational age grading was significantly decreased. The mean corrected gestational ages of the infants corresponding to the ACA classification from grade IV to grade 0 were 32.75±1.89, 37.20±1.30, 39.75±2.38, 40.56±2.24, and 44.23±2.14 weeks, respectively, which were all significantly different (P<0.05). The regression analysis showed a linear correlation between the grading of the ACA and the corrected gestational age (R2=0.724, P=0.0001). Conclusion: The ACA of a full-term newborn can be fully detected and evaluated by a digital fundus camera. For premature infants, part of the ACA is not visible physiologically; however, it should not be misdiagnosed as angle closure or a narrow angle.
