(13) Phakic eyes develop 5-7 diopters of hyperopia when the vitreous cavity is filled with silicone oil, and this puts them in the same range as the silicone oil filled aphakic eyes.
(14) This experiment showed that in every instance the cycloplegic estimate was equal to or greater in hyperopia or less in myopia than when performed without drugs.
(15) Contrary to previous reports, we do not find consistent high hyperopia in the rat, but rather refractions that range from near emmetropia (-0.12 D) to extreme hyperopia (+18.95 D).
(16) A new approach to surgical correction of hyperopia (including aphakia) is advanced.
(17) Although the latter is possible, the hyperopia may be coincidental and masking an underlying mechanism.
(18) We reduced the enlarged blind spot in a patient with focal peripapillary hyperopia, without papilledema, to near normal size by using progressively stronger plus lenses.
(19) Over 30% of the high hyperopes developed strabismus by age 3 years, but none of the infants in the moderate hyperopia or family history groups developed strabismus.
(20) The authors handled 75 such cases by first prescribing spectacles for full correction of hyperopia, and surgical operations were performed to the residual esotropia after wearing the spectacles for 6 months.
Retina
Definition:
(n.) The delicate membrane by which the back part of the globe of the eye is lined, and in which the fibers of the optic nerve terminate. See Eye.
Example Sentences:
(1) The distribution of gelsolin, a calcium-dependent actin-severing and capping protein, in the retina of the developing and adult rabbit was studied.
(2) At day 7 MD occupy about 14% area of posterior retina in transverse sections in Campbell rats versus 7% in normal animals.
(3) Chromatolysis and swelling of the cell bodies of cut axons are more prolonged than after optic nerve section and resolve in more central regions of retina first.
(4) Reverse transcription of retina mRNA followed by DNA amplification using D4-specific nucleotides demonstrates the presence of D4 mRNA in retina.
(5) Electroretinographic (ERG), morphometric and biochemical studies on retinas from monkeys or rats reveal that moderate level developmental lead (Pb) exposure produces long-term selective rod deficits and degeneration.
(6) Cultured cells from fourth to ninth passage showed positive labelling for S 100 protein, carbonic anydrase (CAA), glutamine synthetase (GS), alpha cristallin (alpha C) and polyclonal glial fibrillary acidic protein (GFAP) antibody, but were negative for both monoclonal GFAP antibody and also for Muller cells in the retina.
(7) This study examines the morphology of sporadic congenital microphthalmia in 1-day-old chicks, with particular emphasis on the neural retina.
(8) We based our approach on the anteroposterior location of the incarceration site and the amount of retina incarcerated into the wound.
(9) The posterior retina remained uninvolved, and no further treatment was needed.
(10) On histopathologic examination there were microabscesses in the inner choroid and subretinal space, disrupting the outer retina but sparing the inner retina.
(11) Although the Ca2+-independent mechanism accounts for about two thirds of the total acetylcholine release in the dark, the amount of acetylcholine released in this way is small compared with the release of acetylcholine triggered by stimulation of the retina with light.
(12) These results are consistent with the idea that RPE pigment dispersion is triggered by a substance that diffuses from the retina at light onset.
(13) A specific vitamin A-dependent fluorophore was isolated from these retinas using thin-layer chromatography (TLC).
(14) Premature infants possessed 35-50% higher levels of retinal vitamin C than those found in mature retinas.
(15) The relationship of these observations to the genesis of positional markers in the regenerating retina is discussed.
(16) One may speculate whether clinical conditions exist--apart from hereditary retinal dystrophies--in which the retina becomes more sensitive to light from strong artificial or natural sources, which are otherwise innoxious.
(17) We also used an optical device to stabilize images of the real world upon the retina.
(18) The three-dimensional view obtained with scanning electron microscopy provides another perspective on the pathogenetic changes of the RCS retina.
