Multiple sclerosis, the great masquerader: an atypical ocular presentation.

BACKGROUND: Multiple sclerosis (MS) is the most common chronic disease of the central nervous system and is pleomorphic in it presentations. The optic pathways are frequently involved, and the classic ocular abnormality is optic neuritis. METHODS: A case is presented of a 23-year-old woman in whom optic neuropathy developed and multiple sclerosis was diagnosed by neuroradioimaging, in spite of her lack of awareness of vision loss. RESULTS: The demyelinating lesions in MS may develop anywhere in the visual system and produce a variety of visual defects. Magnetic resonance imaging (MRI) is the most sensitive method for demonstrating these lesions. CONCLUSION: The cause of MS is unknown, but current opinion holds that autoimmunity--perhaps induced by viral infection--is likely to be implicated in its etiopathogenesis. Currently, no method for prevention of MS is known.

Vision readiness in the United States Air Force revisited.

A study was conducted to determine the prevalence of substandard visual acuity in a sample of the diverse communities of the United States Air Force. In addition, mobility readiness (visual), ocular disease, time since last visual examination, and adherence to ocular requirements per AFR 160-43 were assessed. Comprehensive eye examinations were performed in the Optometry Clinic on 207 randomly chosen members scheduled by Squadron Schedulers using random computer lists of personnel generated by Military Personnel Flight. Of the 207 individuals, 112 (54%) had not had a professional eye examination in the last 2 years, 51 (24%) were not mobility ready, 6 (3%) had inadequate visual acuity per AFR 160-43, and 4 (1.9%) had ocular disease. The study reinforces the concept that comprehensive, periodic ocular examinations should be performed by an optometrist or ophthalmologist on all active duty members to ensure that they see properly to perform assigned duties, that members on mobility have required optical materials to be deployment ready, and that members who develop ocular disease are identified in a timely manner.

Questioning vision readiness in the aviation community of the United States Air Force.

A study was conducted to determine the prevalence of substandard visual acuity in a representative sample of the aviation community. In addition, mobility readiness (ocular), ocular diseases, length of time since last visual examination, and adherence to ocular requirements per AFR 160-43 were assessed. Comprehensive eye examinations were performed in the Optometry Clinic on 68 randomly chosen members scheduled by the participating squadron. Of the 68 individuals, 51 (75%) had not had a professional eye examination in the last 2 years, 17 (25%) were not mobility ready, 15 (22%) had inadequate visual acuity per AFR 160-43, and 3 (4%) had ocular disease. The study suggests that comprehensive visual examinations be performed on a regularly scheduled basis by an optometrist or ophthalmologist to ensure that members see properly to perform assigned duties, that members have required optical materials to be deployment ready, and that members who develop ocular diseases be identified in a timely manner.

Clinical laboratory analysis of white-centered hemorrhages.

The use of laboratory testing can be very helpful in the differential diagnosis of ocular disease. White-centered hemorrhages are associated with many systemic diseases. This paper discusses how the differential diagnosis of the associated medical condition can be accomplished through a systematic evaluation of patient history, ocular examination, and laboratory testing.
