Incidence and severity of ocular and systemic adverse events (AEs) and serious adverse events (SAEs)
Tijdsspanne: From informed consent through end of participation (up to 27 months)
|
Safety of topical sterile human insulin (EYED-002) in patients with open-angle glaucoma.
AEs and SAEs classified using MedDRA nomenclature, assessed for severity (mild, moderate, severe) and causality.
Safety monitoring includes glycemia measurements before and 2 hours after in-clinic insulin administration, and serial serum electrolyte (potassium) measurements.
