Orbital cellulitis secondary to adjacent paranasal sinusitis presents with marked proptosis, ophthalmoplegia, eyelid edema, chemosis, and/or conjunctival hyperemia. These conditions often precede visual dysfunction. "Posterior" orbital cellulitis secondary to sphenoethmoidal sinusitis may be defined as the clinical syndrome in which early severe visual loss overshadows or precedes accompanying inflammatory orbital signs. The visual loss may be attributed to involvement of the intracanalicular or orbital apical segment of the optic nerve. Total irreversible unilateral visual loss developed in three patients with this syndrome. Severe visual loss was preceded by diplopia in one patient and by bilateral eyelid edema in another. One patient with chronic panparanasal sinusitis with acute visual loss presented with isolated optic disc edema. Proptosis and ductional restriction subsequently developed. The irreversible blindness in these cases may be due to a combination of intracanalicular edema and vasculitis causing optic nerve infarction.

Seventeen patients with biopsy-confirmed mitochondrial progressive external ophthalmoplegia underwent electroretinography and visual evoked potential testing to checkerboard-reversal stimuli to investigate subclinical visual dysfunction. Seven patients (41%) had impaired Snellen visual acuity that was never less than 0.6. Thirteen patients (76%) showed electroretinographic and/or visual evoked potential alterations, whereas six (35%) showed impairment on both tests. Two patients showed delayed VEP P100 latency without fundus, electroretinographic or visual acuity anomalies. Visual dysfunctions were not related to age at onset and course of the disease.

Abnormal eye movements in multiple sclerosis (MS) are often persistent and known to be associated with general disability. However, there is no precise knowledge concerning their incidence and resulting visual handicap. The aim of our study was to describe the persistent ocular motor manifestations in MS and relate them to visual functions tested with visual acuity and with a vision-related questionnaire. We selected 24 MS patients complaining of persistent visual disability associated with ocular motor manifestations without any anterior visual pathway deficit. Internuclear ophthalmoplegia was the most frequently observed symptom, followed by gaze-evoked nystagmus, saccadic hypermetria, and then pendular nystagmus. Pendular nystagmus, saccadic hypermetria, and the association of internuclear ophthalmoplegia and gaze-evoked nystagmus were associated with decreased visual acuity and visual functional scores. There was a correlation between the number of abnormal eye movements and visual functions. This study demonstrates that ocular motor dysfunction in MS induces specific visual dysfunction and handicap.
