Reproducibility in the identification of retinal positions on serial fundus photographs: Theory and limitations

Acta Ophthalmologica, EarlyView.
Abstract Background Imaging of the retina is accompanied by distortions so that positions in fundus photographs cannot be linearly translated to positions in the retinal fundus. The purpose of this study was to describe an algorithm and evaluate its reproducibility in identifying points on the retina from their representation on serial fundus ...

Single oral administration of dronabinol increases ocular blood flow in patients with glaucoma

Acta Ophthalmologica, EarlyView.
Abstract Purpose Glaucoma is a leading cause of irreversible blindness globally, primarily driven by elevated intraocular pressure (IOP). Still, some patients progress despite significant IOP lowering, potentially due to impaired ocular blood flow. This study aimed to evaluate the effects of dronabinol, a synthetic tetrahydrocannabinol derivative, on ...

Repeatability of retinal vessel flicker responses in healthy individuals

Acta Ophthalmologica, EarlyView.
Abstract Purpose To determine the repeatability of retinal blood vessel parameters (from proprietary software and the raw vessel data) measured in vivo in healthy individuals at rest, during and post flicker light (FL) provocation using a standardised protocol.
