ABSTRACT
OBJECTIVE: This paper documents the clinical, ultrasound, magnetic resonance imaging (MRI), and anatomic characteristics of 6 patients with esohypotropia and high axial myopia. The results of strabismus surgery performed on these patients are evaluated. STUDY DESIGN: Retrospective cohort study. PARTICIPANTS: Six patients with esohypotropia and high axial myopia were selected from the practice of the second author (Michael Flanders). METHODS: We extracted the history and data from the preoperative and postoperative ophthalmic and orthoptic examinations, recorded the surgical procedures, and tabulated the postoperative results. A- and B-scans, orbital MRI images, and photo documentation were obtained for all patients. Supramaximal recession and resection on the horizontal rectus muscles, using adjustable sutures, was performed in all patients. A surgical outcome was deemed successful if, in primary position, postoperative horizontal ocular alignment measured 15 prism diopters (PD) or less and (or) if diplopia was eliminated. RESULTS: Echographic and MRI findings demonstrated an enlarged globe in all cases. Globe flattening on the orbital walls was found in 5 cases. Lateral rectus depression was visualized on MRI images in 4 cases. Surgical success was obtained in all patients. The average preoperative primary position esotropia measured 60 PD (25 to 90 PD) and the esodeviation after surgery was 7.0 PD (0 to 15 PD). Ductions were also improved. CONCLUSIONS: Different surgical approaches to realignment of eyes with high myopia and esohypotropia have been attempted. In this study, supramaximal amounts of recession and resection on the rectus muscles provided satisfactory results.

PURPOSE: To evaluate the use of the 20-MHz ultrasound probe in facilitating visualization of the posterior lens capsule in ocular trauma. DESIGN: Interventional case report. METHODS: Serial examinations using 10-MHz, 20-MHz, and 50-MHz ultrasound technologies were performed on the anterior segment of the right eye of an 18-year-old man referred with a diagnosis of globe penetration and secondary traumatic cataract. RESULTS: Cross-sectional echograms of the anterior segment using the 20-MHz ultrasound showed posterior lens capsule integrity. CONCLUSION: When verifying the status of the posterior lens capsule in cases of ocular trauma, the 20-MHz ultrasound probe is a useful and novel approach.
