biostudies-literatureUnknown70(3)Maheshwari DWe 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.Indian journal of ophthalmology1051-1053https://www.ebi.ac.uk/biostudies/studies/S-EPMC9114598biostudies-literatureEarly outcomes of 21-gauge needle-guided <i>ab interno</i> tube sulcus placement of a non-valved implant in pseudophakic eyes.PMC9114598Kadar MARao SMaheshwari DPawar NRamakrishnan RfalseEarly outcomes of 21-gauge needle-guided <i>ab interno</i> tube sulcus placement of a non-valved implant in pseudophakic eyes.We 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.
