Purpose
To assess the proportion of patients with raised intraocular pressure (IOP) (≥ 30 mmHg) on the first postoperative day following pars plana vitrectomy (PPV), encirclement and endotamponade and assess the number requiring alteration in management to address elevated IOP. To establish whether review on day one is required.
Methods
Retrospective case note review of consecutive patients who underwent 23-gauge PPV, 276-encirclement and endotamponade under the care of a single surgeon. All patients as standard received prophylactic anti-glaucoma medication post-surgery (eye drops) to take home but initiate only after day-one review. Statistical analysis was carried out using student t tests and Fisher’s exact tests.
Results
Sixty-six patients were examined over a 2-year period. Mean day-one IOP was 22.2 mmHg (SD 7.3, 95% CI 20.4–24.0). Eleven patients (16.7%) had IOP ≥ 30 mmHg. Five patients (7.6%) had management changing decisions made at the day-one postoperative visit. Lens status, endotamponade, preoperative IOP, surgeon grade, cryopexy versus laser retinopexy or preoperative administration of once only 500 mg dose of intravenous acetazolamide did not influence IOP, with no significant difference between these subgroups. No cases of hypotony occurred.
Conclusions
A significant minority of patients had elevation of IOP above 30 mmHg, a number of whom required treatment changes to address this. No preoperative risk factors were identified indicating those at risk of high IOP. It is important to identify these potentially harmful IOP elevations, and therefore day-one review is imperative and should be continued.
