Combined Phacoemulsification and 360-Degree Suture Trabeculotomy Ab Externo in Primary Chronic Angle Closure Glaucoma: A Modified Technique

Both ab externo 360 degree suture trabeculotomy and its modified technique with ab interno pulling of the suture when combined with phacoemulsification are safe and provide adequate decrease in the intraocular pressure. Modified technique of ab interno pulling of the prolene suture might be more gentle procedure with less severe hyphema and lower chance of rupture of trabeculo-Descemet's membrane.
