Аннотация
BACKGROUND: High frequency sonography is used with a medium frequency of 50 to 100 MHz for non-invasive examination of the anterior eye segment. 20-MHz probes are considered to be a cost-efficient alternative, with a lower resolution and a higher penetration depth. We examined the value of the 20-MHz probe in diagnosing chronic canaliculitis.
CASE REPORT: A 50-year-old woman was evaluated for a chronic canaliculitis. A pathognomonic sign of the chronic canaliculitis was the detection of concrements by high-resolution ultrasound. Grains measuring 1-2 mm in diameter could be shown in an ecstatic canaliculus with 20-MHz sonography. The high-resolution sonography showed the extent of the ectasia of the canaliculus and was therefore useful in planing the operative strategy.
CONCLUSION: The spectrum of possibilities in diagnosing chronic canaliculitis is broadened with this diagnostic tool. Specially when characteristic symptoms are missing, the 20-MHz probe may be useful in diagnosing patients with chronic canaliculitis.
