Abstract:
PURPOSE: To evaluate the timing of ocular hypertension (OHT) after pediatric closed-globe injury (CGI) and traumatic hyphema. We hypothesize that OHT will occur at different times based on injury characteristics. DESIGN: Retrospective, cohort study. METHODS: Setting: Single-center, tertiary-care, pediatric hospital. PARTICIPANTS: Subjects included patients ≤18 years of age at the time of injury who suffered CGI and traumatic hyphema between 2002 and 2019. Observation Procedure(s): Intraocular pressure and injury demographics were abstracted for every visit after injury. OHT was defined as >21 mm Hg at presentation or after a reading of ≤21 mm Hg at a prior visit. MAIN OUTCOME MEASURES: The primary outcome measure was the timing of OHT categorized into 4 periods: presentation, acute (days 1-7), subacute (days 8-28), or late (day >28). Secondary outcome measures were identification of risks factors for OHT by multivariable logistic regression. RESULTS: OHT occurred in 119 of the 305 (39%) subject eyes. OHT occurred in 35 patients at presentation, 69 times acutely, 35 times subacutely, and 36 times late. Pupil damage predicted acute-period OHT (P = .004). OHT at presentation predicted subacute period OHT (P = .004). Iridodialysis and cataract predicted late-period OHT (P = .007 and P < .001, respectively). CONCLUSIONS: OHT after CGI and traumatic hyphema in pediatric patients is common. Injury demographics predict this complication. Integration of these risk factors with current literature allows proposal of a risk-stratification tool to guide efficient surveillance for OHT.
