About

Participants were randomised to receive benzalkonium chloride-containing latanoprost (Xalatan) or preservative-free bimatoprost (Lumigan). Through this study, the investigators would like to analyze the impact of different antiglaucoma medications on ocular surface disease in glaucoma patients.

Full description

The purpose of our study is to assess the effect of antiglaucoma medication on ocular surface disease in glaucoma patients before and after treatment with different antiglaucoma medication. All included patients are newly diagnosed with glaucoma and received no previous antiglaucoma treatment. Medical records will be collected prospectively from Sep. 15th 2019 to Aug. 31st 2022. The symptoms and signs of ocular surface disease in each individual will be assessed with questionnaire and clinical exams, including the basal Schirmer's test, non-invasive tear film breakup time, meibography, and in vivo confocal microscopy before and at 1, 3, 6 months after treatment.

Enrollment: 300 estimated patients

Sex: All

Ages: 20 to 80 years old

Volunteers: Accepts Healthy Volunteers

Trial design

300 participants in 3 patient groups

Lumigan PF

Description:

Patients older than 20 years were recruited from the Glaucoma Clinic of National Taiwan University Hospital. Patients were considered eligible for enrolment if they were newly diagnosed with glaucoma and started to receive ocular hypotensive eye drops at our clinic. Eligible patients then received 0.03% bimatoprost (preservative-free) (Lumigan PF, Allergan Inc., CA, USA).

Treatment:

Drug: Lumigan PF; Xalatan

Xalatan

Description:

Patients older than 20 years were recruited from the Glaucoma Clinic of National Taiwan University Hospital. Patients were considered eligible for enrolment if they were newly diagnosed with glaucoma and started to receive ocular hypotensive eye drops at our clinic. Eligible patients then received 0.005% latanoprost (containing 0.02% BAK as a preservative) (Xalatan, Pfizer, NY, USA).

Treatment:

Drug: Lumigan PF; Xalatan

Control

Description:

Patients older than 20 years were recruited from the Glaucoma Clinic of National Taiwan University Hospital. Patients were not diagnosed with glaucoma.
