Intracorneal bacterial colonization in a crystalline pattern
(Springer-Verlag, 1986-05)
We report the case of a 78-year-old woman who developed an intrastromal bacterial colonization 22 months after penetrating keratoplasty. Slit-lamp examination revealed discrete, finely branched, fernlike stromal opacities, ...
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+ ...
Sinusoidal flicker characteristics of the color-sensitive mechanisms of the eye
(Elsevier, 1969-05)
The flicker characteristics of the color-receptive systems of the eye were investigated by measuring the modulation thresholds for sinusoidal flicker of one color superimposed on a background of a complimentary color. A ...
Seeing but not recognizing
(Elsevier, 1986)
Visual recognition disturbances are caused by lesions that affect visual cortex as well as white matter connections between visual cortex and temporal and parietal cortex. Homonymous visual field defects are often present ...
The myopic eye of the black moor goldfish
(Elsevier, 1986)
Optical and anatomical methods were used to establish the refractive state of the eye of the Black Moor variety of goldfish. The eye is strongly myopic. The refractive error in 12 eyes from 6 fish ranged from 89 to 268 D.
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 ...
Invasive squamous cell carcinoma of the conjunctiva presenting as necrotizing scleritis with scleral perforation and uveal prolapse
(Elsevier, 1988)
A 64-year-old white man presented with necrotizing scleritis with scleral perforation and uveal prolapse. Pathologic examination revealed squamous cell carcinoma of the conjunctiva invading adjacent corneal stroma and ...
Lateral spread of light adaptation in the rat retina
(Elsevier, 1977)
Recordings from the rat optic tract fibers were used to assess changes in sensitivity under various conditions of adaptation. An adapting background which excites only a small fraction of the rods can yet cause a several-fold ...
