|- Brief summary||Rationale:|
Eye drops are frequently used for opthalmic drug delivery. An alternative method by means of an ophthalmic spray device, ADE Fluorescein A, has been developed for improved efficiency and convenience.
To demonstrate proof of concept, i.e. equivalent dispersal by both methods.
Proof of concept, pilot study.
Healthy volunteers with healthy eyes.
Topical ocular administration of fluorescein by:
1. Conventional eye drops in one eye versus;
2. ADE Fluorescein A in the fellow eye.
Main study parameters:
Nature and extent of the burden and risks associated with participation, benefit and group relatedness:
Participation requires a single visit to the Rotterdam Eye Hospital which takes about two hours. Participants do not benefit. Risks of topical fluorescein are considered to be low. Autofluorescence measurement is a non-invasive procedure. Burden is moderate.
