Atropine-induced intraocular pressure changes and anterior segment structural parameters in dogs assessed by ultrasound biomicroscopy
Kyung-Mee Park
IntroductionIn dogs, intraocular pressure (IOP) responses to topical atropine administration vary, and the anatomical basis for this variability remains unclear.Materials and methodsUsing ultrasound biomicroscopy (UBM), anterior segment morphology was assessed in 52 eyes from 27 clinically normal dogs before and 20 minutes after atropine administration (post-AT).ResultsThe mean change in IOP was small, but responses varied across eyes. Approximately 29% showed increases considered clinically rel
