Objective To investigate the therapeutic effect of ganciclovir eye drops on herpes simplex keratitis after deep lamellar keratoplasty, and analyze the effects on serum levels of inflammatory factors including IL-6, IL-8, TNF-α and IFN-α. Methods From January 2015 to November 2017, 80 patients with viral keratitis who were treated in Department of Ophthalmology, Xinyang Central Hospital were included. These patients were divided into 2 groups according to random number table. The patients in both groups underwent deep lamellar keratoplasty. The observation group (40 cases) was treated with ganciclovir eye drops after operation, while the control group was treated with acyclovir eye drops. The therapeutic effect, visual acuity, levels of inflammatory factors IL-6, IL-8, TNF-α and IFN-α before and after treatment were compared between the 2 groups. Results The effective rate of treatment in the observation group was higher than that in the control group (92.50% vs. 75.00%, P<0.05), and the incidence of adverse reaction was lower than that in the control group (2.50% vs. 22.50%, P<0.05). The UCVA [(4.83±0.36) vs. (4.52±0.39)], BCVA [(4.31±0.35) vs. (4.10±0.33)] in the observation group were higher than those in the control group after treatment (P<0.05). The serum levels of IL-6 [(50.24±9.67) ng/L vs. (67.52±10.52) ng/L], IL-8 [(68.52±12.05) ng/L vs. (79.52±13.54) ng/L], TNF-α [(76.24±15.13) ng/L vs. (85.24±16.74) ng/L], IFN-α [(95.32±15.69) ng/L vs. (82.51±13.74) ng/L] in the observation group were lower than those in the control group (P<0.05). All patients received regular review and follow-up. During the follow-up period, the rates of virus recurrence (2.50% vs. 7.50%) and matrix immune rejection (2.50% vs. 12.50%) in the observation group were lower than those in the control group (P<0.05). Conclusions Ganciclovir eye drops after deep lamellar keratoplasty can enhance the therapeutic effect of herpes simplex keratitis infection, improve the visual acuity of patients, induce fewer adverse reactions and effectively reduce the body inflammatory reaction injury. |
