Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

The purpose of this study was to asses differences in nycthemeral (24-h) intraocular pressure (IOP) profiles and outflow facilities between patients who have undergone epibulbar microshunt implantation and ab interno trabeculectomy, respectively.

Detailed Description

Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.

Recent studies involving continuous, 24-hour intraocular pressure (IOP) monitoring in glaucoma patients linked IOP variation to disease progression.

No study has previously compared the postoperative IOP variation of microshunt (Preserflo, P) implantation to ab interno trabeculectomy (Trabectome, T).

In this prospective cohort, the investigators analyzed 68 patients (34 P and 34 T) who presented for 24-hour IOP monitoring 6 to 12 months after surgery. Surgery must have been conducted between October 2020 and July 2021. Patients were assigned to each study group according to the intervention undergone, P or T. IOP and tonographic outflow facility were measured in the habitual position using a pneumatonometer. The IOP variation was considered the primary outcome measure.

Study Groups

Review each arm or cohort in the study, along with the interventions and objectives associated with them.

Microshunt patients

Pneumatonometry of the intraocular pressure was performed on patients who have undergone previous microshunt implantation.

Group Type EXPERIMENTAL

Pneumatonometry after microshunt implantation

Intervention Type DIAGNOSTIC_TEST

Pneumatonometry was perfomed over 24 hours at 5 point in time (5 AM, 11 AM, 4 PM, 8 PM, and midnight) using a Pneumatonometer. The measurement was conducted in the habitual position.

Ab interno trabeculectomy patientes

Pneumatonometry of the intraocular pressure was performed on patients who have undergone previous ab interno trabeculectomy.

Group Type EXPERIMENTAL

Pneumatonometry after ab interno trabeculectomy

Intervention Type DIAGNOSTIC_TEST

Pneumatonometry was perfomed over 24 hours at 5 point in time (5 AM, 11 AM, 4 PM, 8 PM, and midnight) using a Pneumatonometer. The measurement was conducted in the habitual position.
