Persistent Hypotony and Annular Ciliochoroidal Detachment After Microhook Ab Interno Trabeculotomy

Abstract

After MIGS, persistent hypotony because of CCD rarely occurs. Increased uveoscleral outflow because of LOT or creation of a cyclodialysis cleft by traction of the pectinate ligament can be a mechanism of CCD development. Young age and myopia can be risks for cyclodialysis cleft formation and hypotony maculopathy after MIGS.
