AIM: To determine the characteristic and regularity of variability of intraocular pressure (IOP) during earlier period from the baseline after vitro-retinal surgery. METHODS: A prospective study was performed in 100 consecutive patients undergoing scleral buckling (23 cases), simple pars plana vitrectomy (35 cases), combined vitrectomy and silicone oil injection (18 cases), combined vitrectomy and C(3)F(8) injection (24 cases). IOP was measured before surgery, and then on day 1, 2, 3, 4, 5, 6 and 7 after surgery with Goldmann applanation tonometer. If IOP > 25 mmHg, the anti-glaucoma medication was administrated by local or systematic therapy. RESULTS: The IOP was elevated significantly in 24 hours after surgery in 86.5% of all cases, and elevated on day 2 and 3 in 8.1% and 5.4% cases, respectively. After undergoing scleral buckling and simple pars plana vitrectomy, the highest mean postoperative I OP was 21.04 ± 7.49 mmHg and 20.43 ± 7.79 mmHg on day 1, respectively. The incidence of high IOP was 5/23 (21.7%) and 6/35 (17.1%) respectively. The highest mean postoperative IOP was 25.17 ± 8.69 mmHg at day 1 after undergoing silicone oil injection and 29.21 ± 10.30 mmHg on day 2 after C(3)F(8) injection. The incidence of high IOP was 10/18 (55.6%)and 16/24 (66.7%)in the silicone oil injection group and in the C(3)F(8), injection group, respectively. CONCLUSION: The elevated IOP occurs usually at an earlier time, especially in 24 hours after vitro-retinal surgery. There were a higher incidence of high I OP and a higher IOP range after silicone oil injection and C(3)F(8) injection. The symptom of the patients cannot be a ruler to judge IOP elevation. It is necessary to measure and control IOP early after vitro-retinal surgery. LA: Chinese
