    Impact of ocular stress on axial length of the eye among young adults

    As our eyes face a new breadth of ocular stressors, it becomes imperative to understand and properly diagnose ocular effects related to stress. This study was aimed at determining the effect of stress on the axial length of young adults.50 subjects of both sexes and between the ages of 15-32 years (mean age of 20.98±3.65 years) were involved in the study. Comprehensive ocular examination including visual acuity using Snellen chart, examination of the anterior segment using penlight, funduscopy using direct ophthalmoscope and ophthalmometry using a one position keratometer to measure the radius of curvature of the cornea of each eye was carried out on all the subjects. The axial length of the subjects was measured twice through ultrasonography using the A-SCAN ultrasound machine. The cumulative mean baseline axial length of the subjects was 23.11mm while the mean induced value was 23.86mm showing an increase in axial length of +0.75mm after exposure to stress. There was a statistically significant (P<0.05) diurnal variation in axial length due to exposure to stress. This signifies a strong correlation between ocular stress and axial length. Stress reduction procedures which involve relaxation should be practised frequently to reduce eyestrain, fluctuations in the eyes axial length and ensure visual clarity.
