Abstract

Mimicking natural anuran biology is a major challenge faced in the husbandry management of frogs, and the quandary of lipid keratopathy in frogs under human care has plagued keepers and practitioners for decades. Unlike corneal lipid dystrophy or lipidosis secondary to degeneration, where there is limited or no vascular in-growth or inflammatory response, lipid keratopathies are associated with vascularization, most often following the appearance of lipid. Hemorrhage from stromal neovascularization has not been described in a frog; however, the presence of vessels in lipid keratopathy certainly heralds the possibility. We report a rather unique case of lipid keratopathy in a 6-year-old female Mission golden-eyed tree frog (Trachycephalus resinifictrix) that not only had concurrent intrastromal hemorrhage, but blue plasmoid staining of the corneal stroma. Current views on both the function of blue plasma in several species and lipid keratopathy are briefly discussed. Overall, evidence suggests that the cause of lipid keratopathy is probably multifactorial and will not successfully be rectified until anuran biology and husbandry are better understood.
