BACKGROUND: Fibrin membrane-induced pupillary block (FMPB) and subsequent glaucoma are rare complications in humans after intraocular surgery, typically managed with neodymium-doped yttrium aluminium garnet (Nd:YAG) laser iridotomy. While this condition is infrequently reported in dogs, it can occur after cataract surgery, with existing treatments being more invasive and less established than in humans.
OBJECTIVE: To evaluate the feasibility and clinical outcomes of Nd:YAG laser membranotomy as a treatment for FMPB in dogs.
METHODS: Two dogs presenting with post-cataract surgery complications, including FMPB and iris bombé, underwent Nd:YAG laser membranotomy. Treatment included preoperative anti-inflammatory and anti-glaucoma therapy, followed by laser procedures targeting fibrin membranes.
RESULTS: Both cases showed immediate relief of pupillary block and reduction of intraocular pressure (IOP). Despite complications including transient uveitis and corneal oedema, Nd:YAG laser treatment effectively resolved FMPB and maintained IOP stability. Vision was preserved in one case, while gradual vision loss occurred in the other due to pre-existing and procedure-related complications.
CONCLUSION: Nd:YAG laser membranotomy may offer a minimally invasive option for managing FMPB in some dogs. It may also be a promising alternative to more invasive procedures when appropriate postoperative care is ensured.
