Vision Research, 1999 Older adults have serious difficulty seeing under low illumination and at night, even in the absence of ocular disease. Optical changes in the aged eye, such as pupillary miosis and increased lens density, cannot account for the severity of this problem, and little is known about its neural basis.

The Absence of FAIM Leads to a Delay in Dark Adaptation and Hampers Arrestin-1 Translocation upon Light Reception in the Retina [PDF]
Cells, 2023 The short and long isoforms of FAIM (FAIM-S and FAIM-L) hold important functions in the central nervous system, and their expression levels are specifically enriched in the retina.

Optical coherence tomography in healthy human subjects in the setting of prolonged dark adaptation [PDF]
Scientific Reports, 2023 Human studies have established that short periods of dark adaptation can induce outer retinal thinning and various band intensity changes that can be detected with Optical Coherence Tomography (OCT).

Recent advances in the dark adaptation investigations [PDF]
International Journal of Ophthalmology, 2015 Dark adaptation is a highly sensitive neural function and may be the first symptom of many status including the physiologic and pathologic entity, suggesting that it could be instrumental for diagnose.

Intrinsic signal optoretinography of dark adaptation kinetics [PDF]
Scientific Reports, 2022 Delayed dark adaptation due to impaired rod photoreceptor homeostasis has been reported as the earliest symptom of eye diseases such as age-related macular degeneration, diabetic retinopathy, and retinitis pigmentosa.

Association of Human Plasma Metabolomics with Delayed Dark Adaptation in Age-Related Macular Degeneration [PDF]
Metabolites, 2021 The purpose of this study was to analyze the association between plasma metabolite levels and dark adaptation (DA) in age-related macular degeneration (AMD). This was a cross-sectional study including patients with AMD (early, intermediate, and late) and

Delayed dark adaptation in central serous chorioretinopathy [PDF]
American Journal of Ophthalmology Case Reports, 2021 Purpose: To evaluate the effect of central serous chorioretinopathy (CSCR) on retinal function using dark adaptation in a human subject, and to follow it through resolution of the disease.

The Mechanism of Dark Adaptation [PDF]
Ophthalmologica, 1962 An analysis is given of the various possible components of the dark-adaptation process. A distinction is made between: Photochemical component (ƒ1), neural receptor component (ƒ2), spatial summation component (D), temporal summation component (T) and a quantum coincidence component (k).

THE KINETICS OF DARK ADAPTATION [PDF]
Journal of General Physiology, 1927 1. Data are presented for the dark adaptation of four species of animals. They show that during dark adaptation the reaction time of an animal to light of constant intensity decreases at first rapidly, then slowly, until it reaches a constant minimum. 2.

Optimising assessment of dark adaptation data using time to event analysis [PDF]
Scientific Reports, 2021 In age-related macular degeneration (AMD) research, dark adaptation has been found to be a promising functional measurement. In more severe cases of AMD, dark adaptation cannot always be recorded within a maximum allowed time for the test (~ 20–30 min ...
