Effect of exophthalmometer design on its accuracy.

PURPOSE: To investigate the effect of the design of different exophthalmometers on their measurement accuracy. METHODS: Eight different exophthalmometers were tested with a specially developed calibrator by experienced orbital surgeons. RESULTS: Exophthalmometers with one mirror and a straight footplate were found to be more accurate than others. One-mirror exophthalmometers were less accurate when assessing low (< or =12 mm) and high (> or =23 mm) exophthalmometric values. CONCLUSIONS: The design of an exophthalmometer affects its accuracy.

Interferon-alpha-associated bilateral simultaneous ischemic optic neuropathy.

The authors describe one patient with essential thrombocytosis and one with chronic hepatitis C infection who developed bilateral simultaneous anterior ischemic optic neuropathy within 3 months of starting treatment with interferon-alpha. One patient had several typical risk factors for conventional AION; the other did not. These cases are the fourth and fifth reported examples of this phenomenon. Interferon-alpha treatment may cause or aggravate the risk of developing anterior ischemic optic neuropathy. Vulnerable patients should be advised of this potential complication, assisted in reducing risk factors, and monitored for optic nerve and retinal vascular complications.
