Methods• Consecutive case study at Calderdale and Huddersfield NHS Foundation Trust.• All patients undergoing pars plana vitrectomy were pseudophakic or underwent combined surgery.• Indications for surgery: MH, ERM or RRD.• None of the patients received  prophylactic anti-glaucoma medication. Results• 164 patients were evaluated on day 1 post surgery.• 10 patients had IOP >30mmHg, incidence 6%• Range 30 – 39mmHg• Mean 32.5mmHg• Incidence of hypotony (< 8mmHg) : 5 (2.7%).Results: Vitrectomy gauge & lens statusIndication23g 25g 27g Phakic PseudoERM 22 14 25 52 9MH 20 13 14 42 5RRD 33 3 20 48 8• No association with postoperative intraocular pressure.Results:Tamponade Number of patientsAir 37          22%C2F6(20%) 74          45%SF6 (20%) 25          15%SF6 (25%) 28          17%• 67 patients had retinopexy during vitrectomy.• 50 patients received laser treatment, 88% in RRD group, 17 had cryotherapy.• Number of laser burns ranged from 11-1489 ( average 712)• IOP elevated by 0.3mmHg for every additional 100 burns (p= 0.028)• Tamponade with C2F6 or SF6 & increasing number of laser burns predisposes to increased IOP.•Incidence of IOP > 30 mmhg is low (6%)in small gauge PPV and phacovitrectomy  TSV without prophylactic antiglaucoma medications.• Incidence of hypotony on day 1 is LOW (2.7%) in tamponade filled eyes.• Prophylactic anti-glaucoma medication is only justified in high risk patients. Conclusion:
