Précis: Postoperative suprachoroidal hemorrhage (PSCH) is an infrequent but devastating complication after nonvalved aqueous drainage implant surgery and demonstrated a bimodal distribution. The final outcomes of either conservative management or surgical drainage of the hemorrhage remained poor. Purpose: The aim was to report the incidence and outcomes of eyes developing PSCH after undergoing Aurolab aqueous drainage implant (AADI) surgery for adult and pediatric refractory glaucomas. Materials and Methods: In this retrospective series, case files of all patients who underwent AADI between May 2012 and December 2019 were retrieved from an electronic database. A PSCH was defined as the presence of hemorrhagic choroidal detachment, confirmed by ultrasound B scan, occurring in a closed system in the postoperative period. Results: Of the 986 eyes that underwent AADI during the study period, 7 (0.7%), developed PSCH (95% confidence interval=0.3-1.6%). There were no differences in the preoperative parameters between those with and without PSCH. Of these, 4 were seen in pediatric eyes (4/288, 1.4%) and 3 in adult eyes (3/698, 0.4%) (P<0.01). Four eyes (57%) had PSCH in the immediate postoperative period (ie, between 24 and 48 h of AADI surgery), while the remaining 3 had onset ranging from 6 to 7 weeks after surgery. Anatomic risk factors were present in all eyes including hypotony (n=4), myopia (n=3), microcornea (n=2), microphthalmos (n=1), postvitrectomy (n=1), and staphyloma (n=1). Visual acuity improved in only 1 (14%) eye while 3 (43%) eyes developed phthisis bulbi, all in the pediatric age group. Conclusions: PSCH is a rare complication following AADI and is seen in <1% eyes. The incidence is higher in the pediatric age group. Visual and anatomic outcomes are dismal following PSCH with globe salvage possible in only about half these eyes.
