  2. 1. Clinical Studies on Dark Adaptation: with Particular Reference to Carotid Artery Disease

    Author : Ulf Havelius; Oftalmologi (Malmö); []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; polycythemia; photoreceptors; phlebotomy; ocular blood flow; headache; dilation lag; dark adaptometry; dark adaptation; color Doppler imaging; carotid artery stenosis; carotid artery disease; carotid endarterectomy; pupil; pupillometry; retinal blood flow; Ophtalmology; Oftalmologi;

    Abstract : Purpose: To study dark adaptation in patients with symptomatic carotid artery disease or polycythemia before and after treatment. This necessitated determinations of pupillary changes as such may influence the findings. To determine whether changes in the retinal blood flow in light and darkness occur in healthy humans.

  4. 2. Selective wavelength pupillometry to evaluate outer and inner retinal photoreception

    Author : Aki Kawasaki; Fatima Pedrosa Domellöf; Bertil Lindblom; Umeå universitet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; pupil; pupil light reflex; melanopsin; photoreceptor; intrinsically photosensitive retinal ganglion cell; oftalmiatrik; Ophtalmology;

    Abstract : PurposeIntrinsically photosensitive retinal ganglion cells (ipRGCs) express a unique photopigment called melanopsin. Capable of direct phototransduction, the ipRGCs are also influenced by rods and cones via synaptic inputs. READ MORE

  5. 3. Diagnosing and monitoring open-angle glaucoma. Pupillometry and other novel techniques

    Author : Lada Kalaboukhova; Göteborgs universitet; []
    Keywords : open-angle glaucoma; relative afferent pupillary defect; pupillometer; visual field; Frequency Doubling Technology Perimetry; High-pass Resolution Perimetry; Heidelberg Retina Tomography;

    Abstract : Aim:To investigate the ability of a custom-built pupillometer and other novel diagnostic instruments to detect and monitor optic nerve damage in glaucoma.Methods:In the first two studies we investigated pupillary reactions to light in patients with glaucoma and in healthy persons using a custom-built pupillometer.

  6. 4. Facilitators of communication and the development of autism : From responsiveness to basic communicative cues, to emerging pragmatic language use

    Author : Maja Rudling; Terje Falck-Ytter; Pär Nyström; Courtenay Norbury; Uppsala universitet; []
    Keywords : SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; Autism Spectrum Disorder; Communication; Auditory responsiveness; Direct gaze; Pragmatics; Pupillometry; Live eye tracking; Infant siblings; Developmental Psychology; Psychology; Psykologi;

    Abstract : When we communicate with others, we use a variety of abilities to facilitate and enable that communication. These abilities range from being responsive to others’ communicative cues to making one’s own communication more functional. Such facilitators of communication has been suggested as atypical in the development of autism. READ MORE

  7. 5. Cognition Seen Through the Eyes of Hearing Aid Users : Working Memory Resource Allocation for Speech Perception and Recall

    Author : Andreea Micula; Jerker Rönnberg; Elaine Hoi Ning Ng; Piers Dawes; Linköpings universitet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Working memory; Free recall; Pupillary responses; Noise reduction; Arbetsminne; Återgivning; Pupillmätning; Brusreducering;

    Abstract : This thesis investigates how hearing aid users allocate working (WM) memory resources under various task demands when listening to and storing speech in memory for later recall. This was done by combining an auditory recall task, the Sentence-final Word Identification and Recall (SWIR) test, with pupillometry. READ MORE
