Abstract Background To determine if 3% diquafosol (DQS) can preserve the meibomian gland morphology in glaucoma patients treated with prostaglandin analogs (PGA) for a 12-month follow-up period. Methods This study included 84 eyes of 46 normal tension glaucoma (NTG) patients who were treated with either preservative-containing PGA (PC-PGA; 16 patients, 28 eyes), preservative-free PGA (PF-PGA; 21 patients, 39 eyes), or a combination of PC-PGA and 3% DQS (PC-PGA + DQS; 9 patients, 17 eyes). The meibography of the upper eyelid was acquired using Keratograph® 5M at baseline and at each follow-up (1, 3, 6, 9, and 12 months). Meibomian gland loss (MGL) was quantitatively analyzed by using ImageJ software. Results In the PC-PGA group, MGL increased significantly from baseline to month 9 and month 12, whereas no significant changes were observed in the PF-PGA and PC-PGA + DQS groups during the entire 12 months. All groups showed similar MGL at each follow-up time from baseline to six months. However, MGL in the PC-PGA group was significantly higher than those in the PF-PGA and PC-PGA + DQS groups at the 9 and 12 months. Conclusions Combining 3% DQS with PC-PGA was as effective as PF-PGA in preserving the meibomian gland morphology for at least 12 months. Our results suggest that 3% DQS may be a promising strategy for managing glaucoma patients with a high risk of developing meibomian gland dysfunction due to preservative-containing topical medications.

Purpose. To compare the ocular pulse amplitude (OPA) lowering effects of preservative-free tafluprost and dorzolamide-timolol fixed combination (DTFC) using dynamic contour tonometry.Methods. In total, 66 eyes of 66 patients with normal tension glaucoma (NTG) (n=34) or primary open angle glaucoma (POAG) (n=32) were included. Patients were divided into two groups: the preservative-free tafluprost-treated group (n=33) and the preservative-free DTFC-treated group (n=33). Intraocular pressure (IOP) was measured using Goldmann applanation tonometry (GAT). OPA was measured using dynamic contour tonometry; corrected OPA (cOPA) was calculated at baseline and at 1 week and 1, 3, and 6 months after treatment.Results. After 6 months of treatment, tafluprost significantly reduced IOP (P<0.001). The OPA lowering effects differed significantly between the two treatment groups (P=0.003). The cOPA-lowering effect of tafluprost (1.09 mmHg) was significantly greater than that of DTFC (0.36 mmHg) after 6 months of treatment (P=0.01).Conclusions. Tafluprost and DTFC glaucoma treatments provided marked OPA and IOP lowering effects. Tafluprost had a greater effect than DTFC; thus, this drug is recommended for patients at risk of glaucoma progression, due to the high OPA caused by large fluctuations in IOP.

Purpose: To analyze the efficacy and safety of preservative-containing and preservative-free 0.2% brimonidine tartrate and 0.5% timolol maleate fixed combination drug in normal tension glaucoma.Methods: Fifty-one patients (84 eyes) who were diagnosed with normal tension glaucoma and with preservative-containing or preservative-free brimonidine-timolol fixed combinations alone were analyzed retrospectively from January 2017 to February 2020. Intraocular pressure (IOP) was measured four times a day (9 a.m., 11 a.m., 2 p.m., and 4 p.m.) before and at 6 months after applying eye drops. We analyzed and compared the effect of lowering IOP and the occurrence of intra or extra-ocular adverse effects.Results: A significant mean IOP reduction was shown in both groups: -1.95 ± 2.50 mmHg (-12.26 ± 15.87%) in the preservative-containing group and -1.60 ± 2.06 mmHg (-10.54 ± 13.94%) in the preservative-free group at 6 months after eyedrop instillation. The IOP was lowest in both groups at 11 a.m. There were no significant differences between the two groups in lowering IOP. Serious adverse effects causing discontinuation of the eye drops were not observed.Conclusions: Both preservative-containing and preservative-free brimonidine-timolol fixed combinations are effective in lowering IOP in normal tension glaucoma patients and are considered to be effective as eye drops without serious adverse effects.
