This paper reports histopathological findings in the spectacles of four snakes diagnosed with systemic gout, inclusion body disease, disseminated lymphoma and myeloproliferative disease, respectively. Gout was characterised by urate ghost tophi in the stroma and outer epithelium of the spectacle. Inclusion body disease affected all layers of the spectacle with intracytoplasmic eosinophilic inclusions. Two cases of neoplasia, lymphoma and myeloproliferative disease, affected the ocular adnexa and the spectacular transition zone. These cases provide novel insight into how the spectacle may respond to four different systemic diseases with world-wide distribution.
