Abstract
OBJECTIVE
To obtain normative ocular data for Japanese quail as they mature from juveniles to adults.
ANIMALS STUDIED
Twenty-six captive Japanese quail comprising thirteen males and thirteen females, free of ocular disease, were included in the study.
PROCEDURES
Ophthalmic reference values were measured in both eyes at 1 and 5 months of age. A complete ophthalmic examination was performed, including neuro-ophthalmic reflexes, slit lamp biomicroscopy, phenol red thread test (PRTT), rebound tonometry, fluorescein staining, horizontal corneal diameter measurement, indirect ophthalmoscopy, and ocular ultrasound biometry. Ultrasound biomicroscopy measurements of axial globe length, lens thickness, vitreal chamber length, and pecten length were recorded. The depth of the anterior chamber was calculated by subtracting the lens thickness and vitreous length from the axial globe length. Measures of association and descriptive statistics were analyzed using STATA-14 and STATA-15.
RESULTS
Juvenile and adult females were heavier than age-matched males. Weight, intraocular pressure, horizontal corneal diameter, axial globe length, and lens thickness measurements increased with age. No statistically significant differences were found in the remainder of measurements among individuals in different sex or age-groups.
CONCLUSIONS
This work provides reference values and clinical findings that can be used in future research on quail and ocular disease.
