Özet

Purpose: To compare preoperative 20 mHz ultrasonography (USG) fi ndings and intraoperative evaluation of the integrity of posterior lens capsuleand anterior hyaloid membrane.Materials and Methods: The study include 51 eyes of 51 patients with traumatic cataract. All patients evaluated with 20 mHz USG preoperativelyand scheduled to undergo cataract extraction. The 20 mHz USG scanning results were entitled as regular, defect and irregular. The intraoperativefi ndings were entitled as regular, aperture with no vitreous and aperture with vitreous.Results: The mean visual acuity of patients with a mean age of 42 ± 19 years (range, 12-82) was 2.3 ± 0.7 log MAR before the surgery. TwentymHz USG showed regularity of posterior lens capsule in 27 patients (%53), irregularity in 21 patients (%41) and defect in three patients (%6).However, the intraoperative evaluation indicated regularity in 30 patients (%59), aperture with vitreous in 19 patients (%37) and aperture with novitreous in two patients (%4). Comparison of the 20 mHz USG and intraoperative fi ndings showed sensitivity, specifi city, positive predictive valueand negative predictive value of %100(100-100), %90 (79.2-100), %87.5 (74.2-100), and %100 (100-100), respectively. Coeffi cient of concor-dance between two methods was 0.853 (0.613-1.093) and observed proportion of agreement was 0.922.Conclusions: In our study we indicated that both posterior lens capsule and anterior hyaloid membrane can be evaluated using 20 mHz USGscanning. Preoperative scanning with 20 mHz USG probe provides valuable informations especially in patients with traumatic cataract.
