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

Dajeong Jeong et al. Vet Med Sci. 2023 Nov.

Abstract

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.

Keywords: ocular ultrasonography; scleral perforation; ultrasound biomicroscopy.

Slit‐lamp biomicroscopy images: (A) fixed miotic pupil and hyphema within the anterior chamber of the right eye; (B) conjunctival haemorrhage and mild chemosis (asterisk) in the dorsal region of the eye; (C) focal bulging (arrowhead) at the dorsomedial region considered as a subconjunctival scleral lesion; (D) hyphema, fibrin clot and aqueous flare in the anterior chamber; (E) intravitreal haemorrhage and fibrinous clots post pupil dilation; irregular posterior lens capsule (F) and intravitreal haemorrhage (G) through slit‐lamp biomicroscopy post‐treatment of anterior uveitis and corneoconjunctival ulcer.

Images of ultrasound biomicroscopy (UBM): (A) UBM image showing disconnected sclera (yellow arrow) having occlusion with hyperechoic material, thought to be prolapsed uveal and fibrinous material beneath the elevated conjunctiva containing subconjunctival fluid (asterisk); (B) UBM image of the dog 1‐month post‐surgery. Sutured sclera (red arrowhead) remains stable. Subconjunctival tissue is thickened, which is thought to be post‐operative fibrous tissue.
