Evaluation of effects of 3% diquafosol ophthalmic solution on preocular tear film stability after trabeculectomy.

OBJECTIVES

To determine the potential effects of 3% diquafosol (DQS) on tear film stability after glaucoma surgery.

METHODS

We retrospectively reviewed consecutive patients who underwent glaucoma surgery at the glaucoma division of the Henan Eye Institute from January 2020 to January 2021. Clinical parameters, including age, sex, intraocular pressure, and number of glaucoma medications, were tested. Tear film parameters, such as tear meniscus height (TMH), first and average noninvasive tear break-up time (FBUT and ABUT, respectively), and tear film lipid layer grade (TFLL), were evaluated using the Oculus Keratograph 5M. We investigated the differences in clinical and tear film parameters pre- and postoperatively. We compared the baseline and different time points after surgery between the DQS and HA groups and identified the factors associated with changes in the tear film at 8 weeks postoperatively.

RESULTS

A total of 101 eyes were included. Early administration of DQS increased TMH, FBUT, ABUT, and TFLL after trabeculectomy (all p < 0.05). In addition, the DQS group showed significantly higher ABUT than the HA group (p < 0.05). DQS use served as an associated parameter for better TMH, FBUT, ABUT, and the TFLL (p < 0.05). DQS and preoperative FBUT were significant independent parameters of postoperative FBUT (p < 0.05).

CONCLUSIONS

The present study showed that postoperative TMH, FBUT, ABUT, and TFLL significantly increased after early application of DQS, and the efficacy of ABUT was better than that of HA at the early stage in 8 weeks after trabeculectomy (p < 0.05).
