This case series describes the ocular, clinical and histologic manifestations of disseminated Aspergillosis in two dogs. Two dogs presented for severe unilateral panophthalmitis and secondary glaucoma with positive Aspergillus spp. titers. Case 1 showed no clinicopathologic systemic symptoms of fungal dissemination, however, case 2 was affected with acute renal failure. The affected eye of case 1 did not respond to medical therapy and was enucleated for comfort. The affected eye of case 2 responded to aggressive topical and systemic medical therapies, however, the patient was euthanized for acute renal failure. Globes were collected for histologic evaluation at the time of death. Histology of both revealed panophthalmitis with presence of significant intraocular hemorrhage, multifocal fungal granulomas, retinal and optic nerve changes consistent with secondary glaucoma, rupture of the anterior lens capsule, and fungal invasion and colonization of the intralenticular space. These cases represent a unique and devastating ocular manifestation of disseminated Aspergillosis. Cases presenting with uveitis and secondary glaucoma of unknown origin, especially with confirmed or suspected lens capsular rupture, should have serologic testing for this infectious agent.
本病例系列描述了两只犬播散性曲霉菌病的眼部、临床和组织学表现。两只犬因严重单侧全眼球炎和继发性青光眼就诊,曲霉菌属滴度呈阳性。病例1未表现出真菌播散的临床病理全身症状,然而,病例2患有急性肾衰竭。病例1的患眼对药物治疗无反应,为缓解痛苦而摘除眼球。病例2的患眼对积极的局部和全身药物治疗有反应,然而,该患者因急性肾衰竭实施安乐死。死亡时收集眼球进行组织学评估。两者的组织学检查均显示全眼球炎,伴有明显的眼内出血、多灶性真菌肉芽肿、与继发性青光眼一致的视网膜和视神经改变、晶状体前囊破裂以及真菌侵入和定殖于晶状体间隙。这些病例代表了播散性曲霉菌病独特而严重的眼部表现。出现不明原因葡萄膜炎和继发性青光眼的病例,尤其是确诊或疑似晶状体囊破裂的病例,应进行该病原体的血清学检测。
