The Form and Function of Retinal Ganglion Cells in Diabetes
CellsThis review examines how diabetes affects the ganglion cells of the retina, including the axons that make up the optic nerve. Links between established changes in the morphology of retinal ganglion cells (RGCs) and vision loss, as well as other functions,

Comparison of acute non-visual bright light responses in patients with optic nerve disease, glaucoma and healthy controls. [PDF]
, 2015 This study examined the effect of optic nerve disease, hence retinal ganglion cell loss, on non-visual functions related to melanopsin signalling. Test subjects were patients with bilateral visual loss and optic atrophy from either hereditary optic ...

CRALBP supports the mammalian retinal visual cycle and cone vision [PDF]
, 2015 Mutations in the cellular retinaldehyde-binding protein (CRALBP, encoded by RLBP1) can lead to severe cone photoreceptor-mediated vision loss in patients.

Invisible light inside the natural blind spot alters brightness at a remote location
Scientific Reports, 2018 The natural blind spot in the visual field has been known as a large oval region that cannot receive any optical input because it corresponds to the retinal optic disk containing no rod/cone-photoreceptors. Recently, stimulation inside the blind spot was

Influence of Strategic Cortical Infarctions on Pupillary Function
Frontiers in Neurology, 2018 Objective: Cortical activity, including cognitive and emotional processes, may influence pupillary function. The exact pathways and the site of cortical pupillary innervation remain elusive, however. We investigated the effects of select cortical strokes,

Evaluation of two portable pupillometers to assess clinical utility
Concussion, 2020 Background: Pupillometers have been proposed as clinical assessment tools. We compared two pupillometers to assess measurement agreement. Materials & methods: We enrolled 30 subjects and simultaneously measured the pupil diameter and light reflex ...

Pupillary light reflex in amblyopia.
Investigative ophthalmology & visual science, 1984 The pupillary light reflex of 15 strabismic and anisometropic amblyopes, and eight subjects who had recovered from functional amblyopia was studied by using an infrared electropupillogram. Ten of the fifteen amblyopes had significantly longer latencies of contraction when the amblyopic eyes were stimulated than when the normal eyes were stimulated ...
