Suprachoroidal hemorrhage associated with pars plana vitrectomy

Abstract Purpose To analyze the characteristics, related risk factors, and prognosis of suprachoroidal hemorrhage (SCH) associated with pars plana vitrectomy (PPV). Methods Cases SCH PPV excluding trauma were retrospectively analyzed in Beijing Tongren Hospital between January 2010 June 2020. The data collected included general data, myopia status, axial length, state crystalline lens, onset time, range, treatment method, visual prognosis, methods operation anesthesia. Patients divided into those to first (Group 1), second intraocular surgery vitrectomized eye 2). also classified by time either expulsive group (ESCH) delayed (DSCH). different groups analyzed. Results was studied 28 cases an incidence 0.06 %; 16 males 12 females. mean age patients (53.51 ± 10.21) years old, follow-up (24.94 14.60) days, length (28.21 3.14) mm. Of these cases, 21 as high myopia, 25 aphakia/ pseudophakic, 7 focal hemorrhage. Silicone oil removal occurred (43 %). Group 2 younger than 1 ( P = 0.005). In terms 5 eyes simply closely observed, 4 given single drainage, 15 drainage combined silicone tamponade, underwent anterior chamber puncture, gave up treatment. A vision: NLP ~ 20/30; among them, (7.14 %), 6 ? 20/200 (21.43 final outcomes presented a significantly positive correlation baseline vision but no significant or length. Conclusions has higher rate after which is lack vitreous support easier fluctuation pressure. more localized relatively good prognosis; aphakic/ pseudophakic are factors. Active can effectively improve prognosis. Trial registration Retrospective case series study, not applicable.
