OBJECTIVES: To evaluate the clinical outcomes of chemical ciliary body ablation (CBA) in dogs with chronic glaucoma and concurrent anterior lens luxation and to investigate adverse ocular effects of this procedure. PROCEDURES: Retrospective review of 17 dogs (18 eyes) with chronic glaucoma and concurrent anterior lens luxation treated with intravitreal gentamicin with or without dexamethasone sodium phosphate or triamcinolone acetonide. Data collected included signalment, concurrent ocular disease, topical medications prescribed, follow-up duration, and intraocular pressure (IOP) pretreatment, posttreatment, and at the last follow-up visit. Success was defined as an IOP <25 mmHg with no additional procedures or ocular hypotensive medications at the last examination to date. RESULTS: The success rate for CBA in dogs with chronic glaucoma and concurrent anterior lens luxation was 88.9% without the need of additional surgical or ocular hypotensive therapies. Glaucoma was suspected to be secondary to lens luxation in 72.2% of cases. The most common postoperative complications were phthisis bulbi (50.0%), keratoconjunctivitis sicca (27.8%), and uveitis (27.8%). Long-term management with topical nonsteroidal anti-inflammatories, corticosteroids, and/or immunomodulators was needed in 70.6% of cases. CONCLUSIONS: CBA with intravitreal injection of gentamicin is effective at maintaining an IOP <25 mmHg in dogs with chronic glaucoma and concurrent anterior lens luxation. Management of postoperative sequelae commonly requires continued use of topical medications.
