Figure 1: Right eye. Note marked aqueous flare,
hyphaema and hypopyon. There were also multifocal
areas of dense melanosis in the iris and posterior
synechiae (not visible in this image).

neutrophils and bacterial rods and coccobacilli. Some
of the latter were phagocytosed. Diff Quik stain, 400x
The intraocular pressure (TonoVet, Jorgensen
Labs, Loveland, CO, USA) was 36 mmHg OD
(Reference range: 10-25 mmHg).
The left eye (oculus sinister; OS) lacked a
menace response but retained a good
There was diffuse hyphaema and hypopyon,
precluding examination of the lens, posterior
segment and fundus (Figure 2). The
intraocular pressure was 7 mmHg OS.
Figure 2: Left eye. Note diffuse hyphaema and hypopyon.
Figure 3: Ultrasonography: anterior chamber left eye.
Note hyperechogenic foci.
Sonography of the left eye was performed
because anterior segment pathology
precluded posterior segment examination.
However, it did not reveal any retinal
detachments or vitreous haemorrhage.
Hyphaema and hypopyon, seen on slit lamp
examination, were also seen on ultrasound
as hyperechogenic foci in the anterior
chamber (Figure 3).
Aqueocentesis of both eyes (oculus
uterque; OU) was performed under general
anaesthesia, with smears and 0.15 mL
of aqueous humour sent for cytological
analysis. While awaiting the latter results, a
single dose of 1 mg/kg methylprednisolone
sodium succinate (Solu-medrol, Pfizer
Australia Pty Ltd, West Ryde, NSW), was
given intravenously. Topical dorzolamide
