The significance of possible risk factors for the development of complications, including species, sex, age, eye, surgeon, presumed ocular surface infection, cultures, follow-up, antibiotics, NSAIDs, complications and diabetes mellitus was examined in a subset of these patients (2019-2022). As a prospective study, intraoperative blood loss was estimated by gravimetric analysis in an additional subset.Results: Records of 1296 enucleations were retrospectively reviewed and detailed evaluation regarding potential risk factors was performed in 446 enucleations.

Success was defined as full graft integration with globe retention at the last postoperative evaluation; vision status was reported separately. Factors assessed included patient signalment, ophthalmic examination findings, surgical factors, and follow-up information.Results: Conjunctival graft failure occurred in 11% (25/229) of eyes and was significantly associated with ulcer depth, with corneal perforations having increased odds of graft failure compared with descemetoceles (odds ratio [OR] = 3.22, 95% confidence interval [CI] 1.11-9.32; p = .03) and stromal ulcers (OR = 10.89 [95% CI 1.38-86.18], p = .02).

Trans-scleral intraocular lens (IOL) fixation has been described in cases where lens capsule instability precludes the insertion of a prosthetic intraocular lens into the lens capsule. Previous techniques have necessitated enlargement of the corneal incision to accommodate either a rigid polymethylmethacrylate IOL or an acrylic foldable IOL inserted using forceps. This paper reports the modification of an endocapsular IOL to be used as an injectable suture-fixated IOL introduced through a 2.8 mm corneal incision.Materials and methods: All cases underwent lens extraction by phacoemulsification followed by removal of the unstable lens capsule. A PFI X4 IOL (Medicontur) was modified to create four open-loop haptics. The IOL was injected into the anterior chamber, each haptic was captured in a loop of suture introduced ab externo, and the lens was sutured with four-point fixation.Results: The results from 20 eyes in 17 dogs are reported. Over an average follow-up time of 14.5 months, vision was retained in 16/20 eyes.

Selected dogs had surgical iridectomies performed.Results: Iridal melanocytic lesions were characterized as well-delineated, pigmented, and flat (nevus) or raised (mass) lesions of the iris. Forty dogs (18 Labrador retrievers, 18 German shepherd dogs, 1 Golden retriever, 3 Labrador/Golden mixes) ranging from 0.5 to 3.1 years of age were affected unilaterally (n = 35) or bilaterally (n = 5). Sector iridectomy was performed in 13 dogs with prominent and well-isolated mass lesion and enucleation was carried out in 2 dogs with extensive lesions, while all other cases were monitored without surgical intervention. Postoperative complications included dyscoria (13/13), focal posterior synechia (9/13) and focal nonprogressive cataract (8/13). All eyes remained visual and comfortable up to 6.2 years post-iridectomy with no clinically identifiable local recurrence. Histopathology was consistent with uveal melanocytoma in all samples obtained surgically. All cases that did not undergo surgery remained free of complications up to 4.5 year post diagnosis.Conclusion: Melanocytic anterior uveal lesions may be overrepresented in certain lineages of breeds and be present at a young age.
