Clinical characteristics of cytomegalovirus positive Posner-Schlossman syndrome and the effect of 20g/L Ganciclovir eye drops intervention / 国际眼科杂志(Guoji Yanke Zazhi)

ABSTRACT

@#AIM: To compare the clinical characteristics of cytomegalovirus positive and negative patients with Posner-Schlossman syndrome(PSS), and the clinical efficacy and short-term recurrence of 20g/L ganciclovir eye drops in local treatment of patients with CMV positive PSS were evaluated. <p>METHODS: Differences between CMV positive(86 cases, 86 eyes)and CMV negative(60 cases, 60 eyes)PSS patients were compared. General information, ocular parameters and distribution, IFN-γ and IL-4 levels in aqueous humor, clinical efficacy and recurrence within 1a were compared between the conventional group(30 cases, 30 eyes)and the experimental group(56 cases, 56 eyes).<p>RESULTS: Among the 146 PSS patients included, the CMV positive rate was 58.9%. The average intraocular pressure and the difference in the number of corneal endothelial cells between the onset eye and the contralateral eye in CMV positive patients were significantly increased, and the number of corneal endothelial cells in the onset eye was significantly decreased(<i>P</i><0.05). After treatment, all ocular parameters and distribution in the experimental group were significantly better than those in the conventional group(<i>P</i><0.05), IFN-γ level in the experimental group was significantly lower than that in the conventional group, and IL-4 level was significantly higher than that in the conventional group(<i>P</i><0.05). Compared with the conventional group, the experimental group had a high total effective rate, a short cure time, a low recurrence rate within 1a and a long recurrence interval, with statistically significant differences(<i>P</i><0.05).<p>CONCLUSION: Patients with CMV positive PSS had higher intraocular pressure and greater damage to corneal endothelial cells than PSS patients with CMV negative. 20g/L ganciclovir eye drops can effectively control intraocular pressure and inflammation by resisting CMV infection, with significant clinical efficacy and not easy to relapse in the short term.
