Ophthalmoscopic examination to inspect the optic disc and retina often requires pupillary dilation using 1% tropicamide and 2.5% phenylephrine; risk of provoking an attack of narrow-angle glaucoma is remote. Visual field mapping by finger confrontation localizes lesions...
Double telecentric optical systems are defined by the fact that the entrance pupil and the exit pupil are (virtually) located at infinity. This means that all chief rays are parallel to the optical axis in object and image space. A chief ray goes through the optical axis at the position of...
Mesopic pupil size increased significantly in both interventional groups compared to placebo by 2.18 mm (95% CI, 1.84–2.52 [adj-P< 0.001]) in the 0.1% atropine loading dose group and 0.42 mm (95% CI, 0.08–0.76 [adj-P= 0.04]) in 0.01% atropine group. ...
