  • Use of punctal occlusion in the treatment of canine keratoconjunctivitis sicca.
    Twenty eyes of 10 dogs with keratoconjunctivitis sicca (KCS) were treated by occlusion of the ventral nasolacrimal punctum with a silicone punctal plug in order to increase the volume of the remaining tear lake.

This was caused by conjunctival adhesions causing symblepharon secondary to a previous septicemia episode. While symblepharon has been noted in birds before, this unusual presentation of the nictitating membrane has not been reported. Surgical in …

  • Intraocular oxygen tensions in normal and diseased eyes of farmed halibut [231Kb]
    Abstract - We have previously documented ocular abnormalities in farmed halibut and reported that the production of gas-filled posterior segment cysts appears to be central in the pathogenesis of many, if not all of the signs in these eyes. In a number of fish, gas bubbles may be seen in the anterior chamber of the eye, especially after trauma or strenuo …

  • Retinal dysplasia in wild otters (Lutra lutra) [3.64MB !]
    Eyes from 88 otters found dead in south-west England between 1990 and 2000, were collected as part of a larger pathological study. Histopathological examination of 131 eyes revealed dysplastic changes such as rosetting and folding in the retinas of 26 of the otters. In the eyes of 42 of the otters there were postmortem and fixation-induced retinal detachm …
