He is also the Principal Investigator at King’s for the TRITON trial, a phase 3b study to evaluate the duration of effect of Bimatoprost SR in participants with open-angle glaucoma or ocular hypertension. Gerassimos has been involved as local Principal Investigator in several glaucoma trials and studies, including a large prospective study investigating the role of mitochondrial function as a novel biomarker for glaucoma in collaboration with Moorfields Eye Hospital and the PEACE trial (randomised trial comparing primary trabeculectomy with primary tube surgery in black African and African-Caribbean patients with uncontrolled open angle glaucoma) in collaboration with St Thomas’ Hospital.
