Assessment of foveal cone photoreceptors in Stargardt's macular dystrophy using a small dot detection task
(Elsevier, 1993-07)
We measured frequency-of-seeing curves for tiny (1.125 and 3.375 min arc) stimuli flashed briefly at absolute threshold to estimate the density of foveal cones in normals and in subjects with Stargardt's macular dystrophy. ...
Extrinsic current and flash sensitivity in turtle cones
(Elsevier, 1994-02)
The effects of hyperpolarizing current and background light on intracellular responses of red cones in turtle were compared. Even though a background light always reduced response amplitude, hyperpolarizing current did so ...
Management of eyelid trauma
(Blackwell Publishing Ltd, 1991-11)
The management of eyelid trauma presents some frustrating challenges to the general ophthalmologist. Because each case is unique, adaptation of general principles is essential for optimal ophthalmic treatment. This review ...
Evidence for a power law intensity code in the coupled cones of the turtle
(Elsevier, 1990)
The hyperpolarizing responses to light were recorded intracellularly from red cones of the turtle, Pseudemys scripta elegans. Pairs of slit stimuli were flashed alone or together at various intensities, one slit positioned ...
Membrane Polarity of the Na+-K+ Pump in Primary Cultures of Xenopus Retinal Pigment Epithelium
(Elsevier, 1994-11)
The retinal pigment epithelium is a transporting epithelium that helps regulate the volume and composition of the subretinal space surrounding photoreceptor outer segments. The capacity of the RPE to actively transport Na+ ...
Square root intensity coding in turtle cones: Physiological mechanisms
(Elsevier, 1990)
The effect of coupling on the intensity-response functions for full field and for slit stimuli was studied by comparing the shapes of the curves obtained from several strongly coupled red cones of turtle with that of one ...
Age related macular degeneration in monozygotic twins and their spouses in Iceland
(Munksgaard International PublishersBlackwell Publishing Ltd, 1999-08)
The scotopic threshold response of the cat erg is suppressed selectively by GABA and glycine
(Elsevier, 1991)
Corneal electroretinograms (ERGs) were recorded from anesthetized cats under scotopic conditions. We examined whether the scotopic threshold response (STR) of the ERG could be functionally distinguished from scotopic PII ...
The peroxisome and the eye
(Elsevier, 1991)
Several childhood multisystem disorders with prominent ophthalmological manifestations have been ascribed to the malfunction of the peroxisome, a subcellular organelle. The peroxisomal disorders have been divided into three ...
