The third eyelid rotation associated with the nictitans gland prolapse and third eyelid cartilage eversion is a rarely encountered ocular disorder. The present retrospective study includes the distribution of the relevant deformations in the cartilage and nictitans gland accompanying the third eyelid rotation in the cat according to breed, age, and gender-based differences, as well as the clinical manifestations, surgical therapeutic approach (partial resection of the scrolled car- tilage portion combined with the Morgan pocket technique), and the outcome of the procedure, concurrently monitoring whether or not the functions of the nictitating membrane were preserved after the procedure, the likelihood of relapse and the potential complications. A total of sixteen eyes surgically treated with the above-mentioned surgical method that belonged to thirteen cats diagnosed with the nictitans gland prolapse and cartilage eversion accompanying the third eyelid rotation were included in the study. The most common breeds were Persian (38.4%) and British shorthair (38.4%), with five cases from each. Three cats (20%) were bilaterally affected, while there was a unilateral involvement in ten of the cases (80%). Out of the ten cases with a unilateral lesion, the right eye was affected in 6 (60%) individuals, while the left eye was involved in four (40%). Nine cats were male, and four were female. The study was conducted in an attempt to surgically correct the third eyelid cartilage eversion and prolapsed nictitans gland responsible for the nictitating membrane rotation in cats by the partial removal of the everted cartilage com- bined with the Morgan pocket technique. Follow-ups were performed twice every other week in the postoperative period, followed by a one-time clinical inspection at the end of the first, third, and sixth months.
第三眼睑旋转伴瞬膜腺脱垂和第三眼睑软骨外翻是一种罕见的眼部疾病。本回顾性研究根据品种、年龄和性别差异，包括猫中与第三眼睑旋转相关的软骨和瞬膜腺相关变形的分布，以及临床表现、手术治疗方法（部分切除卷曲软骨部分并结合摩根袋技术）以及手术结果，同时监测手术后瞬膜的功能是否保留、复发的可能性和潜在的并发症。总共对 13 只患有第三眼睑旋转伴瞬膜腺脱垂和软骨外翻的猫进行了 16 只眼睛的手术治疗，这些猫均采用了上述手术方法。最常见的品种是波斯猫（38.4%）和英国短毛猫（38.4%），每个品种各有 5 只。3 只猫（20%）为双侧受累，10 只为单侧受累（80%）。在 10 例单侧病变中，6 只（60%）为右眼受累，4 只为左眼受累（40%）。9 只为雄性，4 只为雌性。本研究试图通过部分切除外翻软骨并结合摩根袋技术来纠正导致猫瞬膜旋转的第三眼睑软骨外翻和脱垂的第三眼睑。术后每两周进行两次随访，然后在第一个、第三个和第六个月结束时进行一次临床检查。
