“…Induced aqueous humor misdirection syndrome (AHMS) has been reported in a dog [3] and a llama [4] following phacoemulsification, and in humans following penetrating keratoplasty [5], phacoemulsification [6], and neodymium: YAG laser posterior capsulotomy [7]. However, spontaneous AHMS has not yet been described in dogs.…”

An eight-year-old female spayed Boston Terrier presented to the North Carolina Veterinary Hospital with glaucoma in the left eye (OS). Initial ophthalmic examination revealed moderate ocular hypertension, a diffusely and markedly shallow anterior chamber with anteriorly displaced iris and lens, vitreal prolapse, and a normal iridocorneal angle (ICA) morphology. The patient displayed a paradoxical response to topical latanoprost with an increase in intraocular pressure. These examination findings led to a putative diagnosis of spontaneous aqueous humor misdirection syndrome (AHMS). The patient was successfully managed with topical carbonic anhydrase inhibitors (CAIs) and apraclonidine for eight months until progressive ulcerative keratitis necessitated enucleation of the affected globe. Histopathology and high-field magnetic resonance imaging (MRI) of the enucleated globe did not identify an underlying cause for the glaucoma. This case suggests that AHMS should be considered in dogs presenting with a shallow anterior chamber, vitreal prolapse, increased intraocular pressure, and no other causes of glaucoma.

Purpose. To report a case of malignant glaucoma in a pseudophakic female patient, with no history of glaucoma, resolved through pars plana anterior vitrectomy.Case presentation. An 80-year-old female patient presented in our Emergency Department after a five-day history of pain in her left eye (LE). In the last day, the patient noticed marked visual loss and ocular pain. Visual acuity was light perception and Goldman tonometry was 80 mmHg in her LE. The biomicroscopy revealed absent peripheral and central anterior chamber (AC) and posterior chamber (PC) pseudophakia. Posterior segment ecography showed no vitreous or choroidal abnormalities. A peripheral laser YAG iridotomy was made and the patient was treated with intravenous 20% mannitol, topical timolol, topical brimonidine, and topical cycloplegics. 12 hours later, despite a patent iridotomy in the LE eye, intraocular pressure (IOP) was 55 mmHg, absent AC with severe corneal edema. The diagnosis of pseudophakic malignant glaucoma was made and laser YAG capsulotomy was performed with no resolution of symptoms and signs. 24 hours later, we performed pars plana anterior vitrectomy. Postoperatively, the AC depth increased and the IOP decreased to 20mmHg. After a week, the patient was discharged with hand movement perception visual acuity in her LE, 20 mmHg IOP, reduced corneal edema, normal depth AC. After a month, the corneal edema resolved, the visual acuity was 2/50, IOP was 20mmHg, and the AC had a normal depth.Conclusion. Malignant glaucoma is a sight threatening condition, reported in pseudophakic eyes. Although, literature describes cases solved by cycloplegics and laser YAG capsulotomy, our patient needed pars plana anterior vitrectomy for the resolution of symptoms and signs.
