There is a clinical challenge in decision-making regarding prophylactic glaucoma treatment based solely on intraocular pressure (IOP) trends for long-term cataract management or before phacoemulsification surgery canines. This study aimed to compare IOP and ultrasound biomicroscopy (UBM) parameters with maturity small dog breeds. We conducted retrospective review of medical records pertaining ophthalmic examinations UBM assessments breed dogs diagnosed cataracts at the Veterinary Medical Teaching Hospital Seoul National University from January 2020 August 2024. images obtained under topical anesthesia were analyzed quantify various parameters. Subsequently, 47 eyes examined classified into four groups according maturity. The ciliary cleft area (CCA), length (CCL) width (CCW), iridocorneal angle (ICA) measured. measured values compared determine their degree correlation Statistical analyses patient demographics also performed. Both CCA (P=0.0024) CCL (P=0.0004) decreased significantly increasing However, IOP, CCW, ICA not associated Age sex did have significant effects any dependent variable. Among parameters, demonstrated maturity, indicating structural alterations might develop association cataracts, independent direct effects. These findings underscore importance considering patients advanced mitigate potential complications.
