Recruit Status: Unknown status
Study Type: Observational

Official Title: Comparison of the Changes of Lateral Rectus Muscle Insertion Measured With AS-OCT in Two Recession Surgeries

Brief Summary:

Background and study aims : The investigators conducted this study to compare the movement of extraocular muscle after two types of recession surgery with non-invasive tool called AS-OCT.
Who can participate? patients who will undergo two types (conventional method and hang-back method) of typical bilateral lateral rectus recession surgery for correcting intermittent exotropia
What does the study involve? Volunteers will attend a clinic for four visits over three 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 April 2015 to Dec 2015
