• 1 other identifier: 2013-05-026-005
• Study Type: observational
• Target: 30
• Locations: 0 countries
• Sites: N/A

Brief Summary

• Background and study aims : The investigators conducted this study to evaluate the movement of extraocular muscle after strabismus surgery with non-invasive tool called AS-OCT.
• Who can participate? patients who underwent typical lateral rectus recession surgery for correcting intermittent exotropia
• What does the study involve? Volunteers will attend a clinic for four visits over six months. They will undergo AS-OCT at every visits during follow up period. AS-OCT is non-invasive test to evaluate operation site. The test only requires their cooperation when they undergo AS-OCT.
• What are the possible benefits and risks of participating? This is non-invasive test for your postoperative follow up. Therefore, there will be no risks about this test.
• Where is the study run from? Samsung Medical Center
• When is the study starting and how long is it expected to run for? From Feb 2014 to Dec 2014
