A two-year-old spayed female Maltipoo dog was presented with a two-month duration of glaucoma in the right eye. On the first presentation, menace response and dazzle reflex were absent in the right eye, but it was present in the left eye. Slit-lamp biomicroscopy showed buphthalmia, mild corneal edema, and conjunctival and episcleral hyperemia in the right eye. The intraocular pressures were 70 mmHg and 30 mmHg in the right and left eyes, respectively. On the gonioscopic and high-resolution ultrasound examinations, both the iridocorneal angle and ciliary cleft were completely closed in the right eye. However, gonioscopy revealed an opened iridocorneal angle even with some broader base of pectinate ligament fiber, but high-resolution ultrasound showed a narrowed ciliary cleft and increased contact of the iris base with the limbal cornea in the left eye. Based on these results, a diagnosis of primary angle-closure glaucoma was made in both eyes. This case report highlighted the importance of evaluating the ciliary cleft with high-resolution ultrasound as a critical diagnostic and prognostic role in canine glaucoma.

Blepharoplasty is one of the most commonly performed aesthetic procedures. Surgical complications are rare, but can have severe consequences, such as permanent vision loss. In this report, we describe a patient who developed primary angle-closure glaucoma (ACG) with associated vision loss after a oculoplastic procedure using local anesthesia. So far, six similar cases have been described in the literature. It is believed that acute ACG is triggered by the surgical procedure in patients with predisposing risk factors such as a cataract. Surgical triggering factors include the use of buffered lidocaine/xylocaine with adrenaline/epinephrine, stress, and coverage of the eyes postoperatively. Due to postoperative analgesic use, the clinical presentation can be mild and atypical, leading to a significant diagnostic delay. Acute ACG should therefore be excluded in each patient with postoperative complaints by assessing pupillary reactions. If a fixed mid-wide pupil is observed in an ophthalmologic examination, an immediate ophthalmology referral is warranted. Surgeons should be aware of this rare complication in order to offer treatment at an early stage and to minimize the chance of irreversible vision loss.

This study was aimed to evaluate the prophylactic anti-glaucoma effect of topical 5% betaxolol (BTX) and 2% dorzolamide (DRZ) on the second eye in dogs with unilateral primary angle closure glaucoma (PACG). Medical records of 60 dogs with unilateral PACG who received prophylactic anti-glaucoma eyedrops in the second eye, from 2016 to 2021, were reviewed. The prophylactic effects of BTX were maintained on 28/60 (46.7%) eyes until last visit and BTX failure was observed on median 510 (range, 53-1,927) days in 32/60 (53.3%) eyes. After DRZ instillation in BTX failure eyes, the prophylactic effects were extended at median 610 (range, 157-2,270) days in 21/32 (65.6%) eyes. DRZ failure eyes (17/21, 81.0%) eyes required chemical ablation or surgical intervention due to uncontrolled intraocular pressure. The duration of prophylactic effects was decreased with aging (R² = 0.334, p = 0.006). The predominant breeds were Shih-Tzu (41.9%) and American Cocker Spaniel (30.6%) with no significant differences in survival curves (p = 0.210). The average prophylactic effects of BTX persisted more than 1.5 year and could be selected the first prophylactic eye drop in unilateral PACG. Also, early surgical intervention should be considered in prophylactic medications failure cases.

목적: 양안 급성 폐쇄각녹내장 후 발생한 양안 비동맥염 앞허혈시신경병증 1예를 보고하고자 한다. 증례요약: 76세 여자 환자가 하루 전 시작된 양안 통증 및 시력저하로 방문하였다. 양안 시력 0.02, 안압은 우안 52 mmHg, 좌안 50 mmHg, 양안 각막부종과 얕은 전방이 관찰되었으며, 동공은 4 mm로 고정되어 있었다. 만니톨 주사로 안압하강 시킨 후 양안 레이저홍채절개술을 시행하였다. 그러나 2일 후 시력은 우안 안전수지 10 cm, 좌안 안전수지 50 cm로 더 감소되었고 양안 시신경 유두부종이 관찰되었다. 양안 급성 폐쇄각녹내장 후 발생한 비동맥염 앞허혈시신경병증으로 진단하고 경과관찰하였다. 한 달 뒤, 시력은 우안 0.02, 좌안 0.04로 약간 호전되었고, 양안 시신경 유두부종은 사라졌다. 매우 작은 유두함몰비와 시신경 창백과 위축이 관찰되었으며, 표준자동시야검사상 우안은 완전시야결손, 좌안에 상하 수평시야결손이 관찰되었다. 결론: 급성 폐쇄각녹내장이 비동맥염 앞허혈시신경병증의 선행 위험인자가 될 수 있으며, 구심동공운동장애와 유두부종, 다른 위험인자의 동반이 있는 경우 비동맥염 앞허혈시신경병증의 동반 가능성을 고려해야 한다.
