The development of a "reduced logMAR" visual acuity chart for use in routine clinical practice [PDF]

British Journal of Ophthalmology, 2001
The advantages of logMAR acuity data over the Snellen fraction are well known, and yet existing logMAR charts have not been adopted into routine ophthalmic clinical use. As this may be due in part to the time required for a logMAR measurement, this study was performed to determine whether an abbreviated logMAR chart design could combine the advantages ...

Randomized, single‐centre, double‐blinded repeated dose investigation of safety and tolerability of ocular administrations of a novel silica eye drop product in healthy volunteers

Acta Ophthalmologica, EarlyView.
Abstract Purpose Managing ocular diseases often requires frequent eye drop administration, which can challenge patient compliance. A long‐acting eye drop technology using an amorphous synthetic silica composite was developed to address this. Our study aimed to assess the safety and tolerability of the Silica Eye Drop platform in healthy volunteers over

Mesopic microperimetry in Stargardt disease: Application and reliability

Acta Ophthalmologica, EarlyView.
Abstract Purpose Mesopic microperimetry (mMP) is a promising functional endpoint in clinical trials for Stargardt disease type 1 (STGD1). This study evaluated the test–retest variability of mMP and influencing factors, which is essential for ensuring reliability in future STGD1 trials.
