AGE VARIATIONS IN NORMAL HUMAN CONTRAST SENSITIVITYActa Ophthalmologica - Tập 57 Số 4 - Trang 679-690 - 1979
Gunilla Derefeldt, Gunnar Lennerstrand, Björn L. Lundh
The visual contrast sensitivity (the reciprocal of contrast threshold) was studied as a function of age. Psychophysical measurements of binocular and monocular contrast thresholds were made for 33 normal observers at spatial frequencies within the range 0.5 to 40 cycles/degree. The observers were divided into three different age groups: young, middle‐aged, and old subjects with the age ran...... hiện toàn bộ
EFFECT OF THE LENGTH OF WEAR OF CONTACT LENSES ON CORNEAL SENSITIVITYActa Ophthalmologica - Tập 54 Số 6 - Trang 721-730 - 1976
Michel Millodot
Corneal touch thresholds (CTT) were determined once in the morning before inserting contact lenses then after 4, 8 and 12 h of continuous wear. Two groups of subjects participated in this study; 12 persons wearing hard contact lenses and 15 wearing soft contact lenses. All subjects were perfectly adapted to their contact lenses and had worn them for not less than three months. It was found...... hiện toàn bộ
Effect of bicycle ergometer test on intraocular pressure in elderly athletes and controlsActa Ophthalmologica - Tập 71 Số 3 - Trang 301-307 - 1993
Pertti Era, Olavi Pärssinen, Mauri Kallinen, Harri Suominen
ABSTRACT To evaluate the effect of intensive physical exercise on intraocular pressure (IOP) in 66‐ to 85‐year‐old subjects IOP was measured before and after a maximal bicycle ergometer test The non‐glaucomatous subjects comprised 85 male and 36 female athletes and 16 male and 22 female controls of corresponding age drawn from a population register IOP was measured u...... hiện toàn bộ
Effect of inoculum size on the induction of endophthalmitis in aphakic rabbit eyesActa Ophthalmologica - Tập 63 Số 1 - Trang 35-38 - 1985

Abstract. A reproducible animal model is necessary to examine the use of antimicrobial agents for prophylaxis and treatment of bacterial endophthalmitis. We determined the minimum inoculum size of S. aureus and P. aeruginosa that consistently produced endophthalmitis when injected into aphakic rabbit eyes immediately following surgery. Both anterior chamber and intr...... hiện toàn bộ
