Variables recorded included timing to the first PPV, best-corrected final visual acuity (VA) at the last follow-up, incidence of enucleation, type of injury, use of intravitreal antibiotics, number of eye surgeries, use of oral steroids, acetazolamide use, topical steroid use, lens status, silicone oil placement, and zone of injury (1– 3). The ocular trauma score (OTS) was calculated using the variables globe rupture, development of endophthalmitis, initial VA, globe perforation, retinal detachment, and the presence of a relative afferent pupillary defect (RAPD). The primary endpoint was elevated intraocular pressure (IOP) sustained for more than six weeks following PPV. We performed a logistic regression to determine the factors that predicted the development of OHT post-PPV.Results: Of 98 eyes included in the primary analysis, a total of 34 (34.69%) were diagnosed with sustained ocular hypertension (OHT) and 64 (65.31%) remained normotensive. The mean final IOP in the OHT group was 16.96 mmHg and 12.11 mmHg in the normotensive group (P < 0.01). Sex, age, OTS, injury type, zone of injury, preoperative IOP, and final VA were comparable between ...
