Haryana Vet. (Dec., 2018) 57 (2), 243-244 Congenital anophthalmia is defined as complete lack of eye and its associated structures by birth. In cattle, the congenital anophthalmia is associated with other defects like congenital absence of tail and atresia ani (Leipold and Huston, 1968). The anomalous calves were born at full term and had normal vigor and appetite, but were slightly small in size (Moritomo et al., 1995).

Congenital anophthalmia is defined as complete lack of eye and its associated structures by birth. In cattle, the congenital anophthalmia is associated with other defects like congenital absence of tail and atresia ani (Leipold and Huston, 1968). The anomalous calves were born at full term and had normal vigor and appetite, but were slightly small in size (Moritomo et al., 1995). Achondroplastic caprine foetal monster with congenital anury, atresia ani and scrotal hernia was described by Debasis and Mousumi (2009). Perosomus acaudatus (Anury) in a local non-descript milch cow was described by Debasis and Mousumi (2010). In the present case report, congenital anophthalmia associated with congenital atresia ani and anury was reported.
A day old crossbred jersey calf was brought to Veterinary Clinical Complex, College of Veterinary Science, Rajendranagar with a history of weak, debilitated body condition, inability to suckle milk and inability to pass faeces. Calving history of the dam revealed that previously born calves were normal. Physical examination of the calf revealed bilateral congenital anophthalmia, as both the eyes were absent with well developed eyelids (Fig. 1), partial anodontia with one pair of incisors partially embedded in gums (Fig. 2), absence of tail Perosomus acaudatus (congenital anury) and absence of anus i.e. atresia ani (Fig. 3).
