Study Summary

This trial will help establish if changes in retinal blood flow could be an early marker for primary open angle glaucoma.

Who is the study for?
This trial is for adults over 18 with early or pre-perimetric glaucoma, and a control group without glaucoma. Participants must not have had ocular surgery (except cataract surgery/laser trabeculoplasty), no diabetes/hypertension/vascular disorders, no retinal diseases affecting the nerve layer, non-smokers for at least 6 months, and able to be off glaucoma meds for four weeks.Check my eligibility
What is being tested?
The study tests how well blood flow in the retina adjusts itself in people with early-stage open-angle glaucoma using Indocyanine Green Angiography, Isocapnic Oxygen inhalation, and advanced imaging techniques like OCT and AO to potentially identify new biomarkers.See study design
What are the potential side effects?
While specific side effects are not listed for these diagnostic interventions, they may include discomfort from bright lights during imaging procedures or temporary dizziness/breathlessness from inhaling isocapnic oxygen.

Frequently Asked Questions

These questions and answers are submitted by anonymous patients, and have not been verified by our internal team.

Is eligibility for this research study limited to adults over the age of 18?

"Eligible candidates for this medical trial must be 18 to 88 years of age. For those under the legal threshold, there are 23 trials available and 192 for seniors over 65."

Answered by AI

What is the upper bound of participants engaged in this research project?

"Affirmative. According to the clinicaltrials.gov page, this clinical trial is actively recruiting people and was initially posted on May 23rd 2022 with recent edits made on July 19th 2022. The study seeks 90 participants from four different medical centres."

Answered by AI

Who would be eligible to volunteer for this research trial?

"This medical study seeks to recruit 90 people with glaucoma, aged between 18 and 88. In order to be eligible, applicants must meet specific criteria: they have to be over 18 years old; present early stages of the condition according to Hodapp-Anderson-Parrish Criteria; display no definite visual field defects upon standardised automated perimetry assessments (three consecutive exams); lack family history of the disease; feature OCT readings within normal range for their age group in all four quadrants; possess reliable visual fields as deemed by a glaucoma specialist with normal hemifields test values - three or more abnormal"

Answered by AI

What risks could a patient face when undergoing Ocular Imaging with Optical Coherence Tomography (OCT) and Adaptive Optics (AO)?

"There is clinical evidence in favour of Ocular Imaging with Optical Coherence Tomography (OCT) and Adaptive Optics' safety, so it was awarded a score of 3."

Answered by AI

Is this research project currently enlisting participants?

"Affirmative, the patient recruitment process is still ongoing. The trial was initially published on May 23rd 2022 and has since been updated twice; most recently on July 19th of this year. 90 volunteers are needed to be recruited from 4 different medical facilities."
