Intravitreal Fluorinated Gas Preference and Occurrence of Rare Ischemic Postoperative Complications after Pars Plana Vitrectomy: A Survey of the American Society of Retina Specialists

Table 3

American Society of Retina Specialists survey results for intraocular pressure-related events after pars plana vitrectomy with postoperative fluorinated gas.

Event	Yes; n (%)	No; n (%)	If yes, how many times?; (category = n)	Mean years in Practice*; (mean ± SD)
Blinding ischemic event (CRAO, ION)	107 (38)	175 (77)	1 = 58	14 ± 4.7*
			2–5 = 40	19 ± 5.3*
			>5 = 9	19 ± 9.9*
Overall years in practice*; (mean ± SD)	17 ± 5.6	14 ± 5.1	17 ± 5.6	15 ± 10
Therapeutic paracentesis	217 (62)	65 (23)	1 = 51	12 ± 11^†
			2–5 = 90	15 ± 10
			>5 = 76	22 ± 8.8^†
Overall mean years in practice; (mean ± SD)	16 ± 3.8^†	12 ± 4.8	17 ± 5.6	15 ± 10

*No significant differences between means via two sample t-test for yes versus no (P = 0.089) or via one way ANOVA for “yes” subgroup (P = 0.161), SD = standard deviation.
^†Significantly different from “no” via two sample t-test for “yes” versus “no” (P = 0.001), and from overall mean via one-way ANOVA for “yes” subgroup.
