ABSTRACT

Objective:To investigate the efficacy of triamcinolone acetonide injection behind the eyeball in the treatment of Purtscher disease and its effects on vision, inflammatory factors, nitric oxide (NO) and endothelin-1 (ET-1) of aqueous fluid.Methods:A total of 64 patients with Purtscher disease admitted to First People′s Hospital of Lanzhou City from January 2016 to January 2020 were selected and divided into two groups by random number table, with 32 cases in each group. The control group was given conventional treatment, and the observation group was injected with triamcinolone acetonide behind the eyeball on this basis. The total effective rate after 6 weeks of treatment, the best corrected visual acuity and hemodynamic indicators peak flow velocity (V max), end-diastolic flow velocity (V min), resistance index (RI) of ophthalmic artery and central retinal artery during systole, aqueous humor inflammatory factors tumor necrosis factor-α (TNF-α), interleukin (IL)-1β, IL-2, IL-6, NO, ET-1, and adverse reactions after 3 and 6 weeks of treatment were compared between the two groups. Results:After 6 weeks of treatment, the total effective rate in the observation group was higher than that in the control group 96.9% (31/32) vs. 75.0% (24/32), and the difference was statistically significant ( χ2 = 4.655, P<0.05). After 3, 6 weeks of treatment, the best corrected visual acuity in the observation group was higher than that in the control group 0.44 ± 0.13 vs. 0.35 ± 0.12, 0.88 ± 0.16 vs. 0.62 ± 0.15, and the difference was statistically significant ( P<0.05). After 3, 6 weeks of treatment, the V max and V min of the ophthalmic artery and central retinal artery in the observation group were higher than those in the control group after 3 weeks of treatment (29.42 ± 0.93) cm/s vs. (28.65 ± 0.90) cm/s, (8.04 ± 1.08) cm/s vs. (6.95 ± 1.12) cm/s, (8.42 ± 1.21) cm/s vs. (8.39 ± 1.19) cm/s, (4.05 ± 0.61) cm/s vs.(3.58 ± 0.57) cm/s; after 6 weeks of treatment (31.72 ± 1.03) cm/s vs. (29.58 ± 0.95) cm/s, (9.81 ± 1.06) cm/s vs. (7.78 ± 1.15) cm/s, (12.01 ± 1.23) cm/s vs. (10.82 ± 1.07) cm/s, (4.65 ± 0.47) cm/s vs. (4.02 ± 0.36) cm/s; the RI of the ophthalmic artery and central retinal artery in the observation group were lower than those in the control group after 3 weeks of treatment 0.76 ± 0.06 vs. 0.80 ± 0.05, 0.70 ± 0.03 vs. 0.76 ± 0.04; after 6 weeks of treatment 0.71 ± 0.05 vs.0.75 ± 0.04, 0.68 ± 0.04 vs.0.72 ± 0.03, and the differences were statistically significant ( P<0.05). After 3 and 6 weeks of treatment, the levels of TNF-α, IL-1β, IL-2, IL-6 of aqueous fluid in the observation group werelower than those in the control group after 3 weeks of treatment (2.61 ± 0.38) μg/L vs.(4.75 ± 0.41) μg/L, (3.45 ± 0.28) μg/L vs.(6.28 ± 1.05) μg/L, (6.28 ± 0.34) μg/L vs. (9.45 ± 1.14)μg/L, (9.82 ± 1.66) ng/L vs. (12.45 ± 2.31) ng/L; after 6 weeks of treatment (0.98 ± 0.23) μg/L vs. (1.44 ± 0.27) μg/L, (1.11 ± 0.36) μg/L vs. (1.69 ± 0.38) μg/L, (3.68 ± 1.02) μg/L vs. (5.73 ± 1.15) μg/L, (4.11 ± 1.19) ng/L vs. (7.38 ± 1.06) ng/L, and the differences were statistically significant ( P<0.05). After 3, 6 weeks of treatment, the levels of NO in the observation group washigher than that in the control group (56.49 ± 9.17) μmol/L vs. (50.22 ± 8.68) μmol/L, (60.18 ± 8.27) μmol/L vs. (53.24 ± 7.96) μmol/L; the levels of ET-1 waslower than that in the control group (60.77 ± 9.61) ng/L vs. (65.02 ± 10.85) ng/L, (56.59 ± 7.22) ng/L vs. (61.18 ± 6.76) ng/L, and the differences were statistically significant ( P<0.05). The incidence of adverse reactions in the two groups had no statistical significance ( P>0.05). Conclusions:The injection of triamcinolone acetonide behind the eyeball to treat Purtscher disease can improve ocular hemodynamics, inhibit inflammation, improve vascular endothelial function and improve visual acuity. It has significant curative effect and certain safety.
