Detailed Description

The medical records of 116 eyes of 116 patients with pterygium who had pterygium excision and conjunctival autograft between February 2009 and May 2011 were reviewed. Using consecutively recorded photographs, we evaluated preoperative morphologic characteristics and its growth patterns.
