Primary intraocular tumours are infrequent in birds. A 2-year-old male Lady Gouldian finch (Erythrura gouldiae) originally presented to the referring veterinarian after the owner noticed mild swelling of the right eye. After the eye had enlarged rapidly and bulged from the orbit, the bird was seen at the referral hospital. Enucleation was attempted but the bird died after sedation. The eye was removed and, on sectioning, a mass was seen primarily in the vitreous chamber with extension through the sclera to the retrobulbar area. After routine histology, immunohistochemistry and electron microscopy, the mass was diagnosed as an embryonal tumour of probable retinal origin. This type of tumour has rarely been documented in birds and we could find no references to any report in Estrildidae.
原发性眼内肿瘤在鸟类中较为罕见。一只 2 岁雄性华贵黄胸鸟(Erythrura gouldiae),最初因主人发现右眼轻度肿胀而被转诊兽医治疗。在眼部迅速肿大并从眼眶突出后,这只鸟被转诊医院收治。尝试进行眼球摘除术,但在镇静后鸟死亡。取出眼球,切片时可见主要位于玻璃体腔的肿块,并通过巩膜延伸至眼球后区。经过常规组织学、免疫组织化学和电子显微镜检查,该肿块被诊断为视网膜来源的胚胎性肿瘤。这种类型的肿瘤在鸟类中很少见,我们也没有找到任何关于 Estrildidae 家族鸟类中报告的参考文献。
