EDITOR,
Rhinogenic optic neuropathy is a clinical
entity including rhinogenous optic neuritis and optic neuropathy caused by a paranasal cyst. The damage to the optic nerve seems to be caused
mainly by cyst compression and inflammatory changes. Rhinogenic optic
neuropathy secondary to paranasal lesions is not so rare, and paranasal
sinus mucoceles with unilateral blindness have already been reported.
Bilateral loss of light perception caused by rhinogenic optic
neuropathy, however, has not been reported in the literature.
CASE REPORT
A 48 year old man complained of acute visual loss in both eyes. His
corrected visual acuities were light perception in both eyes, and the
light reflex was defective. No remarkable finding was observed on
routine ophthalmic examination. Optic atrophy was not present, and
intraocular pressures were normal. He had a history of surgery for
sinusitis 28 years ago and had been complaining of headache for a year.
