Aqueous Humor Dynamic Components That Determine Intraocular Pressure Variance

Study Overview

This clinical trial focuses on testing the efficacy of different digital interventions to promote re-engagement in cancer-related long-term follow-up care for adolescent and young adult (AYA) survivors of childhood cancer.

Description

Glaucoma is a major cause of blindness. The inability to predict a patient's IOP response to medications is a critical barrier for the clinician to consistently provide highly effective IOP-based treatments. Current trial-and-error approaches to glaucoma management are inefficient and have not addressed this barrier as there are no predictive factors for drug response. Our long-term goal is to improve outcomes by identifying biomarkers and environmental factors that profile a patient at risk for glaucoma by age-of-onset, rate of disease progression, "poor response" to treatment, and large IOP fluctuation. Our purpose of this research project is to address this critical barrier by focusing on physiological factors that predict IOP response to drugs.

  7. * History of acute angle closure crisis in either eye
  8. * History of glaucoma incisional surgery (e.g., trabeculectomy, glaucoma drainage implant, Xen gel stent) in study eye(s)
  9. * History of minimally invasive glaucoma surgery (MIGS, e.g., angle surgery, Cypass) in study eye(s)
  10. * History of any cycloablation surgery (e.g., micropulse or diode transcleral or endoscopic cyclophotocoagulation) in study eye(s)
  11. * Study eye cannot have history of any past SLT or ALT glaucoma laser treatments.
  12. * Study eye(s) cannot have any history of refractive surgery

  22. * Participants must be on minimum 30-day stable regimen prior to Visit 1 for a systemic medication that may affect IOP (i.e., sympathomimetics, beta-blockers, alpha-adrenergic agonists and blockers, calcium channel blockers, angiotensin converting enzyme inhibitors, etc.). Any change of such medication during the study will result in exclusion.
  23. * Prohibited meds during study: cannabis products, brimonidine 0.025% (Lumify), bimatoprost 0.03% for eyelash growth (Latisse), topical ocular and peri-ocular steroids, oral steroids
