A relatively higher intraocular pressure set at the end of vitrectomy is associated with a more stable and rapid visual recovery for patients with vitreous haemorrhage

Purpose To compare structural and functional improvements in patients with vitreous haemorrhage (VH) with different IOPs re‐established at the end of pars plana vitrectomy (PPV). Methods It is a prospective, randomized, comparative, interventional study. Ninety‐five patients with nonclearing VH were...

Description
Summary:Purpose To compare structural and functional improvements in patients with vitreous haemorrhage (VH) with different IOPs re‐established at the end of pars plana vitrectomy (PPV). Methods It is a prospective, randomized, comparative, interventional study. Ninety‐five patients with nonclearing VH were randomized to receive PPV with normalized IOPs of 15 mmHg (Group I: 32 eyes), 25 mmHg (Group II: 32 eyes) and 35 mmHg (Group III: 31 eyes) at the end of surgery. The grade of vitreous opacity and best‐corrected visual acuity (BCVA) on postoperative day 1, week 1, month 1 and month 3 were compared with a mixed model for repeated measures analysis. Results All 3 groups achieved significant improvement on postoperatively in BCVA (p
