Abstract
Objective: This study investigates the anatomical and biomechanical properties of hyperopic eyes and their clinical implications, comparing them with emmetropic eyes to enhance understanding of hyperopia’s impact on ocular health. Methods: A cross-sectional clinical study was conducted on 250 participants (150 hyperopic and 100 emmetropic), aged 5–65 years. Axial length, anterior chamber depth, choroidal thickness, and corneal morphology were measured using advanced imaging tools. Biomechanical parameters, including corneal hysteresis (CH) and corneal resistance factor (CRF), were assessed using an ocular response analyzer. Statistical analyses evaluated correlations between these anatomical features and clinical conditions such as amblyopia and primary angle-closure glaucoma (PACG). Results: Hyperopic eyes exhibited significantly shorter axial lengths (21.86 mm vs. 23.45 mm; p < 0.001) and reduced anterior chamber depths (2.88 mm vs. 3.18 mm; p < 0.001) compared to emmetropic eyes. Choroidal thickness was greater in hyperopic eyes (330.25 µm vs. 285.65 µm; p < 0.001) and correlated negatively with axial length. Steeper corneal curvatures and slightly increased central corneal thickness were also observed. Lower CH and CRF values in hyperopic eyes indicated reduced biomechanical resilience, contributing to a higher susceptibility to PACG. Conclusion: Hyperopic eyes exhibit distinct structural and biomechanical differences, including shorter axial lengths, shallower anterior chambers, and lower CH and CRF, increasing the risk for PACG and amblyopia. These findings emphasize the importance of routine ophthalmic evaluations and targeted interventions to manage hyperopia’s clinical risks effectively.
