Early outcomes of 21-gauge needle-guided ab interno tube sulcus placement of a non-valved implant in pseudophakic eyes. Indian Journal of Ophthalmology. 2022 Mar; 70(3): 1051-10531998-36890301-4738http://imsear.searo.who.int/handle/123456789/224219We report the early outcomes and describe an ab interno 21?G needle technique of sulcus placement of the Aurolab aqueous drainage implant (AADI) tube in nine pseudophakic eyes. IOP reduced from a preoperative mean (SD) of 28.33 (9.80) to 11.56 (2.65) mm Hg and the mean (SD) number of preoperative medications reduced from 3.0 (0.7) to 0.4 (0.9) at 3 months. There were no intraoperative complications noted. This technique of sulcus placement of the AADI tube is a precise technique of tube insertion. It may be an alternative to existing ab externo procedures of tube sulcus placement, limiting multiple blind entries.AADI tubeab internonon?valve implantpseudophakiasulcusJournal ArticleIndiaDepartment of Glaucoma, Aravind Eye Hospital and Post-Graduate Institute of Ophthalmology, Tirunelveli, Tamil Nadu, IndiaDepartment of Paediatric Ophthalmology and Strabismus, Aravind Eye Hospital and Post-Graduate Institute of Ophthalmology, Tirunelveli, Tamil Nadu, India
