(1) We can therefore recommend the use of the Catford Apparatus in very young children and in such cases where the visual acuit can be determined only under very difficult conditions.
Acuity
Definition:
(n.) Sharpness or acuteness, as of a needle, wit, etc.
Example Sentences:
(1) The high incidence of infant astigmatism has implications for critical periods in human visual development and for infant acuity.
(2) We have now started a prospective follow-up study in order to pursue the development of (a) p-ERG amplitudes and (b) funduscopic changes and visual acuity in these patients.
(3) At this threshold there was no effect on reducing the rate of visual acuity overreferrals, but ten children with abnormal binocular vision were detected who were not referred by visual acuity criteria.
(4) Degraded visual acuity had a significant effect on cadence, foot placement, and foot clearance, but visual surround conditions did not.
(5) On the initial visit, the best corrected acuity with spectacles was determined and a potential acuity meter reading was obtained; this test suggested potential for visual recovery in two of the three patients.
(6) Visual acuity was improved in 77%, was worse in 13%, and unchanged in 10% of eyes.
(7) The contra-indications for them are: 1. a better visual acuity with spectacles than with contact lenses, 2. advanced cases (4th degree of Amsler) whose fitting is impossible, 3. unilateral keratoconus, 4. associated diseases such as trachomatous pannus, allergic kerato-conjunctivitis.
(8) Near acuity with distance correction was J2 or more in 93.1% of the bifocals and in 17.4% of the monofocals (without correction: 79.3% and 41.4%, respectively).

(13) We examined 84 eyes with different lens opacities, the visual acuity was analysed in relation to the axial, cortical and capsular cataract.
(14) If there is any advantage to a particular strategy for selecting the distance monovision eye, it must be realized in vision performance areas other than visual acuity.
(15) 9 of the injured eyes had a reduction of visual acuity to 0.5 or less as a consequence of lens or central fundus changings.

(18) Postoperatively, visual acuity was improved and symptoms of erosion decreased in both patients.
(19) Acuity for the direction of drift for these stimuli is of the same order of precision as orientation acuity for static or drifting gratings, and exhibits a meridional anisotropy that favours the principal meridians.
