RAMOS PEREIRA, Yanay et al. Ultrasound biomicroscopy used in patients operated from trauma cataract. Rev Cubana Oftalmol [online]. 2009, vol.22, n.1, pp. 0-0. ISSN 1561-3070.

OBJECTIVE: To characterize the patients operated from trauma cataract through their evaluation with ultrasound biomicroscopy. METHODS: A longitudinal, prospective, observational and descriptive study was conducted in the Microsurgery Service of "Ramón Pando Ferrer" Cuban Institute of Ophthalmology from January 2006 to January 2007. The sample was made up of 72 patients who had been surgically treated using different techniques for intraocular lens implant. RESULTS: Male sex was 72.2 % and the prevailing age group was 40 to 49 years. Crystalline subluxation was found in 16.7 % of cases. Sixty eight percent of patients had normal anterior chamber amplitude regardless of the type of trauma. The most frequent findings by ultrasound biomicroscopy were corneal leukoma, zonular desinsertion, and posterior capsule rupture. The highest percentage with good visual acuity with/without correction after surgery was found in patients with IOL placed in the sac, the most frequent location according to ultrasound biomicroscopy. Rupture of zonular fibers predominated. CONCLUSIONS: Ultrasound biomicroscopy is a diagnostic means of great importante for detection of alterations in the anterior segment of patients operated from traumatic cataract.
