An adult, female red-necked wallaby (Macropus rufogriseus) carrying a joey presented with marked facial swelling on the right-hand side along with a corneal ulcer on the right eye. Numerous diagnostics were utilised in order to evaluate and identify the right maxillary second molar as demonstrating a radiolucent halo around the caudal root. This tooth was subsequently removed and the individual has gone on well to recover post-operatively.
Manual restraint facilitated masking down for general anaesthesia, where the animal was induced using 5% isoflurane (IsoFlo® 100%, Norbrook Labatories) and 1.5L/min oxygen. Once an absence of corneal reflex and relaxing of jaw tone was noted, a rigid, 0 degree 4mm endoscope (Richards®) was used to aid in a full oral examination.
The left maxillary first premolar was noted to be particularly loose, and was simply removed with digital manipulation. Nothing else on the oral examination appeared of concern via oroscopy. The swelling over the right-hand side of the face was identified as a likely abscess through palpation and aspiration, and as such was clipped, lanced using a size 21 scalpel blade and flushed with isotonic fluids (Vetivex 11 (Hartmann’s)®, Dechra Pharmaceuticals, PLC, UK). A central, superficial corneal ulcer measuring 4 x 4mm was identified in the right eye using topical fluorescein stain (Minims Fluorescein Sodium 1%, Bausch & Lomb UK Ltd.,). Topical chloramphenicol 1% treatment was commenced, applied four times daily, to the right eye. Upon this initial examination, it was confirmed that a young joey was being carried within the pouch.

Due to the potential for the joey present within the pouch to be thrown, a purse-string suture could have been placed to ensure retention of the joey, which is a method that would be adopted in further cases in the future .
Although a maxillary nerve block would have been beneficial for multimodal anaesthesia, its potential for adversely affecting the joey was unknown. However, a very recent article published by Rodrigo-Mocholi, et al., describes the use of a maxillary nerve bock in a lactating red-necked wallaby, without adverse effects being observed to either the wallaby or joey present within the pouch .
An alternative to oral or injectable medication would have been the possibility for placement of antibiotic-impregnated polymethylmethacrylate beads. The use of these in a red-necked wallaby has been described by Hartley, et al., and could have provided an appropriate alternative to more frequent stressful handling associated with other methods, such as administration of injectables .
