Objective: To evaluate the use of autologous lamellar keratoplasty for the treatment of feline corneal sequestrum (FCS)., Procedure: The medical records of cats diagnosed with FCS that underwent autologous lamellar keratoplasty between 2012 and 2020 with a minimum of 2 months of follow-up were reviewed. After keratectomy of FCS, a button adjacent to the corneal limbus was harvested on the same eye and sutured to the recipient bed. A nictitating membrane flap was left in place until the first recheck except for one patient. Postoperative treatment with topical and systemic antibiotics and systemic nonsteroidal anti-inflammatory medications was prescribed. Follow-up examinations were carried out 2 weeks, 1 month and 2 months post-operatively and consisted of a complete ophthalmic examination., Results: A total of 35 cats (35 eyes) were included. The median follow-up time was 3.2 months (range, 2-59 months). Brachycephalic cats were overrepresented (85.7%). The mean graft size was 6.5 mm (range, 6-9 mm). Minor complications consisting of melting and partial integration of the graft occurred in 2/35 eyes (5.7%). Recurrence was observed in 1/35 eyes (2.9%) and was managed by a superficial keratectomy. A good visual outcome was achieved in all eyes, and a faint or mild corneal opacification occurred in 15/35 (42.9%)., Conclusions: Autologous lamellar keratoplasty is an effective treatment for FCS, providing good tectonic support to the affected cornea and resulting in good visual and cosmetic outcomes. These results should be verified in future prospective studies that include a larger number of cases and longer-term follow-up., (© 2021 American College of Veterinary Ophthalmologists.)

Objective: To evaluate the results obtained using Morgan pocket technique and chondrectomy (MPTC) alone, or combined with a wedge conjunctivectomy (MPTC + WC) for the treatment of prolapsed gland associated with cartilage deformity of the nictitating membrane (PGCD) in dogs., Procedure: Medical records of dogs diagnosed with PGCD that received a MPTC or MPTC + WC were reviewed between 1998 and 2018. Success rate was defined by lack of recurrence of the prolapsed gland with a minimum of 6 months follow-up. Histological examination of the excised cartilage was performed in 13 eyes., Results: A total of 132 dogs (181 eyes) met the inclusion criteria. Median follow-up time was 25 months (range, 6-166 months). MPTC was used in 131 eyes with 91.6% success rate. MPTC + WC was used in 50 eyes with 100% success rate. Postoperative complications occurred in 6.9% and 4%, respectively, for MPTC and MPTC + WC, including lacrimal cysts (8 eyes) or corneal erosion (3 eyes). Recurrence and complications rates were significantly lower using MPTC + WC compared with MPTC in the giant breed dogs (P = .019 and P = .002, respectively), but not in the overall study population (P = .328 and P = .290, respectively). Histological cartilage anomalies were noted in 2/13 specimens from chronic PGCD., Conclusions: MPTC + WC offers a good therapeutic option for giant breed dogs with PGCD. The combined technique provides a good apposition and mobility of the nictitating membrane onto the ocular surface and potentially reduces the risk of recurrence in these giant canine breeds., (© 2019 American College of Veterinary Ophthalmologists.)
