(3) This is due to the wisdom and farsightedness of King Abdul Aziz Al-Saud, who, to reorganize the Saudi-Arabian people and establish his sovereignty, adopted the divine law of the Koran, the Sharia, as the only law applicable to control all individual and social relationships and to combat crime.
(4) The Finnish Twin Cohort material was used to estimate genetic and environmental effects in the etiology of hyperopia (farsightedness).
(5) During his time at Glasgow, Bob had isolated stem cells from early rabbit embryos, work which similarly displayed the farsightedness that pervaded his research.
Presbyopia
Definition:
() A defect of vision consequent upon advancing age. It is due to rigidity of the crystalline lens, which produces difficulty of accommodation and recession of the near point of vision, so that objects very near the eyes can not be seen distinctly without the use of convex glasses. Called also presbytia.
Example Sentences:
(1) The most common eye disease are cataract, refractive error and presbyopia, and diseases of the conjunctiva and sclera.
(2) In addition some individuals (7%) were found to develop early presbyopia.
(3) Their use for presbyopia, aphakia, and glaucoma is considered.
(4) Both the decrease in retinal illumination and the presbyopia accounted for only a trivial proportion of the acuity loss.
(5) Detailed understanding of these mechanisms and the environmental, dietary, and behavioural factors that may influence the development of presbyopia will require controlled studies and, in some cases, invasive experimental manipulations that can only be achieved through the use of an animal model.
(6) Diagnostic standards have a big practical importance in the ophthalmological geriatrics above all in glaucoma, apart from the presbyopia, which depends to the age in a big way.
(7) Complications, such as scarring from intersecting keratotomy incisions, irregular astigmatism resulting from multiple reoperations, and overcorrections with the attendant early onset of symptomatic presbyopia are becoming much less frequent.
(8) The results are described of a 10-year study of the longitudinal changes in the static response of an individual subject during the approach to absolute presbyopia.
(9) They present a variable refractive index which can be used to produce the necessary addition needed for presbyopia.
(10) The history of prostheses for presbyopia is reviewed with an account of the development of variable focus spectacles.
(11) All forms of ophthalmic correction for presbyopia require compromises in viewing flexibility and visual function.
(12) A 33-year-old white man developed premature presbyopia and anisocoria as initial manifestations of acute pandysautonomia.
(13) The corneoscleral incision could be made even smaller, the lens diaphragm would be conserved more physiologically, and a method of therapy for presbyopia might eventually be possible.
(14) The resulting data indicate significantly lower best-corrected distance visual acuities, a greater prevalence of many ocular pathologies, less frequent occurrence of myopia, and an earlier onset of presbyopia than is found in the general United States population.
(15) Is it true that environmental UVR is also the prime contributor in the deleterious lenticular changes that may begin with premature presbyopia, as has been postulated?
(16) The age at onset of presbyopia showed a slightly higher rate of concordance in the MZ than in the DZ pairs.
(17) Monovision, the use of a monocular addition for near viewing, is a clinical technique sometimes used to correct presbyopia.
(18) The genetic and environmental contributions to physical aging (hair graying, balding, presbyopia) and longevity (age at death) were examined by within-pair comparison in monozygotic (MZ) and dizygotic (DZ) twins in later adulthood.
(19) Presbyopia, cataract, and glaucoma are some of the visual constraints that may play an important role in making it difficult for the person to read the informed consent form.
(20) We have conducted two experiments to investigate the effect of monovision and other contact lens corrections for presbyopia upon peripheral visual acuity.
