Privitera C, Noah S, Carney T, Klein S, Lenartowicz A, Hinshaw S, et al.
Neurosci Lett . 2025 Feb; 851:138148. PMID: 39914659
We investigated the phenomenon of pupillary unrest in individuals with Attention Deficit Hyperactivity Disorder (ADHD) compared to neurotypical controls. We measured the power of low-frequency pupil oscillations under two experimental...

Privitera C, Noah S, Carney T, Klein S, Lenartowicz A, Hinshaw S, et al.
Neurosci Lett . 2023 Nov; 818:137556. PMID: 37951300
ADHD is a neurocognitive disorder characterized by attention difficulties, hyperactivity, and impulsivity, often persisting into adulthood with substantial personal and societal consequences. Despite the importance of neurophysiological assessment and treatment...

Privitera C, Neerukonda S, Aiyagari V, Yokobori S, Puccio A, Schneider N, et al.
BMC Neurol . 2022 Jul; 22(1):273. PMID: 35869429
Background: Automated infrared pupillometry (AIP) and the Neurological Pupil index (NPi) provide an objective means of assessing and trending the pupillary light reflex (PLR) across a broad spectrum of neurological...

Rajan R, Deb A, Lomte S, Privitera C, Kannan N, Ramasamy K, et al.
Indian J Ophthalmol . 2021 Sep; 69(10):2746-2750. PMID: 34571627
Purpose: The occurrence of relative afferent pupillary defect (RAPD) secondary to optic nerve diseases and widespread retinal disorders is well established. However, only very few reports of RAPD in macular...

Buch K, Bouffard M, Kardon R, Wills A, Privitera C, Sharma M, et al.
J Neuroophthalmol . 2021 Aug; 42(2):246-250. PMID: 34417776
Background: Supranuclear vertical gaze palsies and slowed vertical saccades are characteristic clinic features of progressive supranuclear palsy (PSP). The "hummingbird sign," reflective of midbrain atrophy, is a classic radiographic sign...

Boehm A, Privitera C, Schmidt B, Roorda A
Biomed Opt Express . 2019 May; 10(4):1691-1706. PMID: 31061763
Tracking SLO systems equipped to perform retinally targeted stimulus delivery typically use near-IR wavelengths for retinal imaging and eye tracking and visible wavelengths for stimulation. The lateral offsets between wavelengths...

Pillai M, Sinha S, Aggarwal P, Ravindran R, Privitera C
Indian J Ophthalmol . 2019 Jan; 67(2):227-232. PMID: 30672475
Purpose: The relative afferent pupillary defect (RAPD) is an important sign of asymmetrical retinal ganglion cell damage. The purpose of this study was to quantify RAPD by a pupillometer (RAPiDo,...

Privitera C, Sabesan R, Winter S, Tiruveedhula P, Roorda A
Opt Lett . 2016 Apr; 41(8):1728-31. PMID: 27082330
Objective measurements of transverse chromatic aberration (TCA) between two or more wavelengths with an adaptive optics scanning laser ophthalmoscope (AOSLO) are very accurate, but frequent measurements are impractical in many...

Privitera C, Carney T, Klein S, Aguilar M
Vision Res . 2013 Dec; 95:43-50. PMID: 24333280
During free viewing visual search, observers often refixate the same locations several times before and after target detection is reported with a button press. We analyzed the rate of microsaccades...

Privitera C, Renninger L, Carney T, Klein S, Aguilar M
J Vis . 2010 Oct; 10(10):3. PMID: 20884468
It has long been documented that emotional and sensory events elicit a pupillary dilation. Is the pupil response a reliable marker of a visual detection event while viewing complex imagery?...
