Purpose To describe successful intraocular pressure control of refractory glaucoma and vision preservation with an endocyclophotocoagulation (ECP) procedure by pars plana approach. Animal Studied An 8‐year‐old, female‐spayed, mixed‐breed goniodysgenic dog with glaucoma following phacoemulsification with intraocular lens placement (IOL) refractory to maximized medical therapy and Ahmed gonioimplantation in both eyes (OU). Procedures For the first glaucoma interventional surgery, bilateral goniovalve implantation was performed following cataract surgery. A goniovalve was implanted in the left eye (OS) 2‐days post‐phacoemulsification, and 14‐days post‐phacoemulsification in the right eye (OD). Short‐term intraocular pressure (IOP) control was achieved. However, glaucoma recurred 41‐days post‐phacoemulsification OU, and an endocyclophotocoagulation by pars plana approach was performed OU to treat 300° of the ciliary body with a 23‐gauge argon laser endoscope. Results Th ECP pars plana approach was successful in obtaining IOP‐control and vision preservation during a 15‐month follow‐up period. No intraoperative complications were encountered. Short‐term postoperative complications included intraocular inflammation with fibrin and postoperative ocular hypertension. Intraocular pressure‐control and vision preservation were maintained at the last follow‐up examination, 15 months postoperative pars plana ECP. Conclusion Endocyclophotocoagulation by pars plana approach achieved long‐term (>1 year) IOP‐control, preserved vision, and reduced the number of anti‐glaucoma medications following failure of previous Ahmed gonioimplantation for uncontrolled glaucoma. This is the first case report of an endocyclophotocoagulation procedure by a pars plana approach for uncontrolled glaucoma following Ahmed gonioplantation. With the appropriate skill set, this novel surgical approach can be considered as a surgical intervention for glaucoma in canine patients.

To perform a reconstructive blepharoplasty to obtain complete surgical excision of a darkly pigmented raised conjunctival-eyelid mass of the lower eyelid in a dog.Animal studied: A 7-year-old, female-spayed, Yorkshire Terrier was evaluated for a slowly progressive, dark brown-to-black raised mass of the lower left eyelid.Sampling of the mass via fine-needle aspirate or incisional biopsy was declined, and an excision of the mass with the goal to obtain complete margins and maintain normal eyelid function with cosmesis was elected. Procedures:The lower palpebral conjunctival-eyelid pigmented mass was excised en bloc and the lower eyelid was reconstructed with a mucocutaneous subdermal plexus flap.Results: Histopathology revealed a malignant dermal and conjunctivalmelanoma excised with complete margins (1-2 mm). Short-term complications included corneal ulceration and eschar formation, which resolved completely at the 1-month follow-up. Long-term complications included mild trichiasis with epiphora and porphyrin staining. Tumor recurrence was not observed during an 8-month follow-up period. Conclusions: The en bloc excision with mucocutaneous subdermal plexus flap was successful in obtaining complete surgical margins for a malignant conjunctival-eyelid melanoma. An excellent functional and cosmetic outcome was achieved without tumor recurrence during an 8-month follow-up period. A mucocutaneous subdermal plexus flap can be considered as a surgical option for malignant melanoma of the lower eyelid.
