A bullous spectaculopathy is an accumulation of clear fluid in the subspectacular space that presents as a bulging of the spectacle. It is a common problem caused by the blockage of the nasolacrimal duct, which is often secondary to infectious stomatitis. In newborn snakes it may be caused by a congenital agenesis of the lacrimal duct.

Bulging spectacles are a common presenting complaint in snakes.  The cause may either be a subspectacular infection or impaired tear drainage. On physical examination the subspectacular fluid tends to be clear when there is impaired drainage. If the fluid is not clear an infectious process should be suspected. The vascularity is not usually evident in the normal spectacle. When there is distension of the spectacle the vessels may become engorged and easily visualised with an ophthalmoscope.
