Lens-related emergencies need immediate medical intervention to reduce complications, minimize pain, and improve the chances of retaining vision. The present study aimed to demonstrate the common lens-related ocular emergencies in dogs and evaluate the short-term outcomes after the treatment of these cases. Sixty dogs (90 eyes) of different breeds were presented with unilateral (30 eyes, OD = 18, OS = 12) and bilateral (60 eyes) ocular abnormalities related to crystalline lens injury. Clinical, ultrasonographic, and laboratory examinations were achieved. Different treatment protocols were conducted after a complete ophthalmic examination and the associated clinical outcomes were evaluated. Mean (± SD) age of dogs at initial evaluation was 3.65 (± 2.4) years (range, 1˗12 years). Lens luxation and subluxation were diagnosed in 45 eyes (25 with anterior lens luxation, 15 with subluxation, and 5 with posterior lens luxation). Lens-induced anterior uveitis without ocular hypertension (n = 25 eyes), lens-induced uveitis with secondary glaucoma (uveitic glaucoma) (n = 15 eyes), and lens capsule disruption (n = 5 eyes) were also diagnosed. The vision was lost in all 5 eyes with posterior lens luxation and secondary glaucoma (100%), 18/25 eyes with anterior lens luxation (72%), and 5/15 eyes with lens subluxation (33.3%). Vision impairment was also identified in 10/25 eyes (40%) with unresponsive lens-induced anterior uveitis and in 5/5 eyes (100%) with traumatic rupture of the anterior lens capsule. Crystalline lens pathology can cause a wide variety of ocular emergencies that may result in blindness. Early diagnosis and appropriate treatment are crucial for handling lens-related emergencies in dogs.

犬晶状体相关眼部急症 (LROE)：90 只眼睛晚期就诊后的治疗和视力结果

与晶状体相关的紧急情况需要立即进行医疗干预，以减少并发症、最大程度地减少疼痛并提高保留视力的机会。本研究旨在证明狗常见的与晶状体相关的眼部紧急情况，并评估这些病例治疗后的短期结果。60 只不同品种的狗（90 只眼睛）出现与晶状体损伤相关的单侧（30 只眼睛，OD = 18，OS = 12）和双侧（60 只眼睛）眼部异常。完成了临床、超声检查和实验室检查。在完整的眼科检查后实施不同的治疗方案并评估相关的临床结果。初次评估时狗的平均 (± SD) 年龄为 3.65 (± 2.4) 岁（范围，1˗12 岁）。45只眼被诊断为晶状体脱位和半脱位（25只眼为前晶状体脱位，15只眼为半脱位，5只眼为后晶状体脱位）。还诊断出不伴有高眼压的晶状体诱发的前葡萄膜炎（n = 25 只眼）、伴有继发性青光眼（葡萄膜炎性青光眼）的晶状体诱发的葡萄膜炎（n = 15 只眼）和晶状体囊破裂（n = 5 只眼）。晶状体后脱位和继发性青光眼全部 5 只眼（100%）视力丧失，晶状体前脱位 18/25 眼（72%），晶状体半脱位 5/15 眼（33.3%）。10/25 只眼睛 (40%) 因晶状体诱发的前葡萄膜炎反应迟钝，5/5 只眼睛 (100%) 因晶状体前囊外伤性破裂而出现视力障碍。晶状体病变可引起多种眼部紧急情况，可能导致失明。早期诊断和适当的治疗对于处理狗与晶状体相关的紧急情况至关重要。
