Development of a clinically feasible logMAR alternative to the Snellen chart: performance of the "compact reduced logMAR" visual acuity chart in amblyopic children [PDF]

open access: yesBritish Journal of Ophthalmology, 2003
The "compact reduced logMAR" (cRLM) chart is being developed as a logMAR alternative to the Snellen chart. It is closer spaced and has fewer letters per line than conventional logMAR charts. Information regarding the performance of such a chart in amblyopes and children is therefore required.

LogMAR and Stereoacuity in Keratoconus Corrected with Spectacles and Rigid Gas‐permeable Contact Lenses [PDF]

open access: yesOptometry and Vision Science, 2018
SIGNIFICANCE This study showed an improvement in three‐dimensional depth perception of subjects with bilateral and unilateral keratoconus with rigid gas‐permeable (RGP) contact lens wear, relative to spectacles. This novel information will aid clinicians to consider RGP contact lenses as a management modality in
