Virginia Street, Reno, Nevada 89557, USA 2University of California, Department of Ophthalmology & Vision Science, Davis, California 95616, USA *Corresponding author: [email protected] Received 9 October 2015; revised 13 December 2015; accepted 20 December 2015; posted 21 December 2015 (Doc. ID 251656); published 3 February 2016 Color perception is known to remain largely stable across the lifespan despite the pronounced changes in sensi- tivity from factors such as the progressive brunescence of the lens. However, the mechanisms and timescales controlling these compensatory adjustments are still poorly understood. In a series of experiments, we tracked adaptation in observers after introducing a sudden change in lens density by having observers wear glasses with yellow filters that approximated the average spectral transmittance of a 70-year-old lens. Individuals were young adults and wore the glasses for 5 days for 8 h per day while engaged in their normal activities. Achromatic settings were measured on a CRT before and after each daily exposure with the lenses on and off, and were preceded by 5 min of dark adaptation to control for short-term chromatic adaptation. During each day, there was a large shift in the white settings consistent with a partial compensation for the added lens density. However, there was little to no evidence of an afterimage at the end of each daily session, and participants’ perceptual nulls were roughly aligned with the nulls for short-term chromatic adaptation, suggesting a rapid renormalization when the lenses were removed.

  • Color Perceptions of Deuteranopic and Protanopic Observers by Deane B
    U. S. Department of Commerce Research Paper RP1922 National Bureau of Standards Volume 41# October 1948 Part of the Journal of Research of the National Bureau of Standards Color Perceptions of Deuteranopic and Protanopic Observers By Deane B. Judd It is well established that about 2 percent of otherwise normal human males are con- fusers of red and green from birth. There is considerable interest in the question: What do red-green confusers see? From a knowledge of the normal color perceptions corresponding to deuteranopic and protanopic red and green, we may not only understand better why color-blindness tests sometimes fail, and so be in a position to develop improved tests, but also the color-deficient observer may understand better the nature of his color-confusions and be aided to avoid their consequences. If an observer has trichromatic vision over a portion of his total retinal area, and dichromatic vision over another portion, he may give valid testimony regarding the color perceptions characteristic of the particular form of dichromatic vision possessed by him. Preeminent among such observers are those born with one normal eye and one dichromatic eye. A review of the rather considerable literature on this subject shows that the color perceptions of both protanopic and deuteranopic observers are confined to two hues, yellow and blue, closely like those perceived under usual conditions in the spectrum at 575 and 470 m/x, respectively, by normal observers. By combining this result with standard response functions recently derived (Bureau Research Paper RP1618) for protanopic and deuteranopic vision, it has been possible to give quantitative estimates of the color perceptions typical of these observers for the whole range of colors in the Munsell Book of Color.

Moon, MD, CM, MSc, FRCP(C), FACP, FCCP * † There have been many complications associated with transurethral resection of the prostate (TURP), known as TURP syndrome. Of the various irrigation fluids used for TURP, glycine irrigant has been historically popular given its relatively low cost. It is also a nonconductive solution and only slightly hypoosmolar, reducing the risk of burn injury or significant hemolysis. However, there have been many case reports of central nervous system toxicity such as transient blindness and encephalopathy related to glycine toxicity.

  • The Effect of Cataract Surgery on Circadian Photoentrainment a Randomized Trial of Blue-Blocking Versus Neutral Intraocular Lenses
    The Effect of Cataract Surgery on Circadian Photoentrainment A Randomized Trial of Blue-Blocking versus Neutral Intraocular Lenses Adam Elias Brøndsted, MD,1,2 Birgit Sander, Cand Scient,1 Birgitte Haargaard, MD, PhD,1,2 Henrik Lund-Andersen, MD, DMSc,1,2 Poul Jennum, MD, DMSc,2,3 Steen Gammeltoft, MD, DMSc,4 Line Kessel, MD, PhD1,2 Purpose: Cataract decreases blue light transmission. Because of the selective blue light sensitivity of the retinal ganglion cells governing circadian photoentrainment, cataract may interfere with normal sleepewake regulation and cause sleep disturbances. The purpose was to investigate the effect of cataract surgery on circadian photoentrainment and to determine any difference between blue-blocking and neutral intraocular lenses (IOLs). Design: The study was a single-center, investigator-driven, double-masked, block-randomized clinical trial. Participants: One eye in 76 patients with bilateral age-related cataract eligible for cataract surgery was included. Methods: Intervention was cataract surgery by phacoemulsification. Patients were randomized to receive a blue-blocking or neutral IOL. Main Outcome Measures: Primary outcome was activation of intrinsic photosensitive ganglion cells using post-illumination pupil response (PIPR) to blue light from 10 to 30 seconds after light exposure as a surrogate measure. Secondary outcomes were circadian rhythm analysis using actigraphy and 24-hour salivary melatonin measurements. Finally, objective and subjective sleep quality were determined by actigraphy and the Pittsburgh Sleep Quality Index. Results: The blue light PIPR increased 2 days (17%) and 3 weeks (24%) after surgery (P < 0.001). The majority of circadian and sleep-specific actigraphy parameters did not change after surgery.

  • The Impact of Age-Related Cataracts on Colour Perception, Postoperative
    Ao et al. BMC Ophthalmology (2019) 19:56 https://doi.org/10.1186/s12886-019-1057-6 RESEARCH ARTICLE Open Access The impact of age-related cataracts on colour perception, postoperative recovery and related spectra derived from test of hue perception Mingxin Ao1, Xuemin Li1, Weiqiang Qiu1, Zhiqiang Hou1, Jie Su1 and Wei Wang1,2* Abstract Background: Cataract patients were always excluded from studies on ageing of colour vision; thus, effect of age- related cataracts on deterioration of colour perception has not been analysed. In present study, impacts of age- related cataracts on colour discrimination, postoperative recovery and related spectra were investigated. Methods: In this cohort study, thirty age-related cataract patients scheduled for binocular surgery and 30 elderly volunteers were enrolled. Colour discrimination under photopic (1000 lx) and mesopic (40 lx) conditions was evaluated with Farnsworth-Munsell 100-hue test. The total error score (TES) and partial error score (PES) were calculated. Results: Preoperatively, the TES in the patient group was 129.7 ± 59.5 at 1000 lx and 194.6 ± 74.5 at 40 lx, exhibiting worse discrimination than the volunteer group (TES1000lux =71.5±37.5andTES40lux =113.1±38.8,p ≤ 0.001). Inferior perception were detected in the yellow to green-yellow (Y-GY), green-yellow to green (GY-G), green to blue-green (G-BG) and blue-green to blue (BG-B) colour bands (p ≤ 0.003), corresponding to the 470 nm–580 nm range of the visible light spectrum. Under mesopic conditions, the impact expanded to all colour bands except for yellow-red to yellow (YR-Y).
