Diagnosis of traumatic scleral perforation in a dog using ocular ultrasound and ultrasound biomicroscopy

A 10‐year‐old spayed female Maltese dog was presented for hypotony of the right eye (OD) with decreased vision. The dorsomedial region of conjunctiva was partially swollen but the globe remained intact. Slit‐lamp biomicroscopy revealed intraocular haemorrhage, uveitis, and a limbal, corneoconjunctival ulcer near the swollen conjunctiva. During ocular ultrasonography (OUS), the sclera became indented and hypotony occurred, implicating a full‐thickness scleral wound. Ultrasound biomicroscopy (UBM) confirmed a full‐thickness scleral defect, which was surgically apposed. The intraocular pressure normalised and the uveitis subsided post‐operatively. OUS and UBM were helpful in suggesting and definitively diagnosing scleral perforation, leading to accurate treatment and good prognosis.
