Introduction:
Brucellosis is a zoonotic infectious disease with a wide range of
manifestations including malaise, anorexia, fever, and profound muscular
weakness, as described by Marston in 18601. It is
caused by the Gram-negative coccobacillus, Brucella, and remains endemic
in some developing countries, such as Iran. There are 6 types of
brucella that 4 of which include Brucella melitensis, Brucella abortus,
Brucella canis, and Brucella suis were recognized as pathogens involving
humans. Brucella melitensis was described as the most common and
virulent pathogen worldwide. The first case of ocular brucellosis in a
human being was described by Lemaire in 1924 2,
presented with bilateral optic neuritis and external ophthalmoplegia in
a patient with brucella meningitis.
Ocular manifestations of acute and chronic infection include anterior
and posterior uveitis, panuveitis, keratitis, conjunctivitis,
papillitis, cataract, maculopathies, glaucoma, and ocular muscle
paresis. Modern treatments of ocular brucellosis, intraocular as well as
systemic antibiotics, have improved the prognosis of the
disease3. Herein, we present a patient with endogenous
endophthalmitis caused by Brucella Melitensis (B.Melitensis), which is
very rare and unusual.
