Entropion and ectropion occur in rabbits,
especially in loose-skinned breeds such as the
French lop. Short nosed breeds, such as the
Netherland Dwarf, are prone to inadequate
tear drainage and epiphora due to the conformation
of the lower eyelid. Taut eyelids, a
shallow medial canthal lake or mild medial
lower lid entropion compromise drainage of
tears through the punctum lacrimale. The
natural bend in the nasolacrimal duct at the
lacrimal foramen and at the base of the upper
incisor can be enhanced in flat-faced individuals
with a short, distorted nasolacrimal duct.

Hyperplasia of the bulbar conjunctiva results
in a circular flap of tissue that grows over the
cornea.
The condition can be unilateral or
bilateral and the term ‘precorneal membranous
occlusion’ has been used to describe it.
The aetiology is unknown (Wagner et al.,
1998).
The flap is not adherent to the cornea and
often does not affect vision. Treatment is not
always necessary. Surgical excision is
straightforward but the membrane tends to
grow back within weeks. Extending the
excision to a few millimetres posterior to the
limbus was successful in a case described by
Dupont et al. (1995). Alternatively, postoperative
topical cyclosporin therapy can be used
in an attempt to prevent regrowth.
i info o chorobie Buphthalmii (Choroby wieku niemowlęcego, wzrost płynu wewnątrzgałkowego i konsekwencji rozszerzenia gałki ocznej. Zwany także jaskrę wrodzoną) :
Buphthalmia is an autosomal recessive trait in
rabbits that causes unilateral or bilateral
enlargement of the eyeball with secondary
changes in the cornea. It can occur in rabbits
of any breed. The age of onset is variable.
Changes have been observed in baby rabbits
as early as 2–3 weeks of age (Lindsey and
Fox, 1994). The disease is due to a decrease in
drainage of aqueous humour from the
anterior chamber and a rise in intraocular
pressure. Corneal oedema, conjunctivitis and
increased prominence of the eyeball occur
and, in severe cases, corneal ulceration can
result in rupture and collapse of the eye with
subsequent scarring and healing. The condition
can be unilateral or bilateral. Protrusion
of the anterior chamber gives rise to the term
‘moon eye’ that is sometimes used by breeders
to describe the condition (Bauck, 1989). At
one time, it was hypothesized that vitamin A
deficiency was involved in hereditary
buphthalmos. The theory was tested on
rabbits of the hereditary buphthalmic strain
with various levels of vitamin A. However,
no correlation between intraocular pressure
and serum vitamin A levels could be found
(Fox et al., 1982).

Box 11.1 Treatment of epiphora and
dacryocystitis
• Radiography is indicated to confirm or
negate the presence of underlying dental
disease
• Dacryocystography using an iodinated
contrast medium can be used to outline
the nasolacrimal duct
• General anaesthesia is required for effective
irrigation of the nasolacrimal duct. It
is a procedure that can be distressing for
the rabbit
• Irrigation of the nasolacrimal duct should
be done gently. It is possible to cause
soft tissue damage, especially with metal
catheters. Rupture of the duct or lacrimal
sac can occur if excessive pressure is
applied
• It is sometimes necessary to pass a
cannula through the lacrimal foramen to
flush purulent material from the maxillary
section of the nasolacrimal duct. The
lacrimal foramen is illustrated in Figure
11.3
• Bacteriological culture of material
flushed from the nasolacrimal duct aids
antibiotic selection
• After flushing, antibiotic eye drops or
ointment can be introduced into the duct
through the catheter
• Systemic antibiotics are indicated in
severe infections. Parenteral cephalexin
is a useful antibiotic for the treatment of
dacryocystitis, especially in combination
with cefalonium eye ointment
• Long-term topical eye ointment is often
indicated
• Manual expression of pus from the
lacrimal sac two or three times a day can
be helpful. Owners can be shown how to
do this
• A bonded rabbit companion can be very
effective in keeping the lacrimal sac
empty and cleaning fur around the eye.
Licking and cleaning the face is a part of
normal mutual grooming behaviour
• Underlying dental disease needs to be
treated. Diet and husbandry changes are
often necessary.
