Uveitis and pupillary block glaucoma in an aphakic dog

Area of Science:

• Ophthalmology
• Veterinary Medicine
• Surgical Innovation

Background:

• Unilateral uveitis, pupillary occlusion, and secondary glaucoma are serious ocular conditions in dogs.
• Aphakia following cataract surgery can predispose eyes to complications like uveitis and glaucoma.
• Prompt diagnosis and intervention are crucial for preserving vision in affected animals.

Observation:

• A 2-year-old Miniature Schnauzer presented with blepharospasm in the left eye, four months post-cataract surgery.
• Ocular examination revealed anterior uveitis, characterized by pupillary occlusion and iris bombé.
• The affected eye was aphakic, increasing the risk of intraocular pressure elevation.

Findings:

• A neodymium:YAG (neodymium:YAG) laser iridotomy was performed to improve anterior chamber depth.
• Iridencleisis was utilized to surgically create a functional pupil, restoring ocular anatomy.
• Post-operative follow-up showed the eye remained visual and normotensive over a six-month period.

Implications:

• This case demonstrates the efficacy of combined neodymium:YAG laser iridotomy and iridencleisis in managing complex ocular conditions in dogs.
• The surgical approach offers a viable solution for restoring vision and ocular health in aphakic patients with secondary glaucoma.
• Successful management highlights the importance of advanced surgical techniques in veterinary ophthalmology.
