What's the difference between acuity and thickness?

Acuity


Definition:

  • (n.) Sharpness or acuteness, as of a needle, wit, etc.

Example Sentences:

  • (12) In remote terms (after four months) further improvement of visual functions was recorded, visual acuity increased by 0.3-0.6 in 8 of 15 patients.
  • (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.

  • (17) The final visual acuity was 0.4 or better in 83.3% of the eyes with transient CME.
  • (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.
  • (20) The CNVMs were treated in four patients; final visual acuity was poor in all eight patients.

Thickness


Definition:

  • (n.) The quality or state of being thick (in any of the senses of the adjective).

Example Sentences:

  • (1) The variation in thickness of the LLFL may modulate the species causing damage to the cells below it.
  • (2) An increase in membrane thickness was observed on phosphorylation.
  • (3) All patients with localized subaortic hypertrophy had left ventricular hypertrophy (left ventricular mass or posterior wall thickness greater than 2 SD from normal) with a normal size cavity due to aortic valve disease (2 patients were also hypertensive).
  • (4) Milk yield and litter weights were similar but backfat thickness (BF) was greater in 22 C sows (P less than .05) compared to 30 C sows.
  • (5) The enzyme was quantitated by incubation of 16-micron-thick brain sections with 0.07-2 nM of the converting enzyme inhibitor 125I-351A and comparison to 125I-standards.
  • (6) Grafts of intermediate thickness (M III) showed excellent clinical healing of the donor and the recipient site.
  • (7) At 7 days axonal swellings were infrequently observed and the main structural feature was a reduction in myelin thickness in affected nerve fibers.
  • (8) Suspensions of isolated insect flight muscle thick filaments were embedded in layers of vitreous ice and visualized in the electron microscope under liquid nitrogen conditions.
  • (9) The NAD-dependent enzymes (except alpha-GPDH) showed a stronger reactivity in the proximal tubules, while the NADP-dependent ones were more reactive in the thick limb of Henle's loop and distal convoluted tubules.
  • (10) In clinical situations on donor sites and grafted full-thickness burn wounds, the PEU film indeed prevented fluid accumulation and induced the formation of a "red" coagulum underneath.
  • (11) These early hyperplastic lesions revealed stellate-shaped dilated bile canaliculi lined by blebs and abnormally thick elongated microvilli, a decreased number of microvilli on the sinusoidal surface, a marked increase in smooth endoplasmic reticulum, large nucleoli, and bundles of pericanalicular microfilaments.
  • (12) The degree of overlap varies with the thickness of the arborization and is in the order of 1-2 mu.
  • (13) The spatial resolution of a NaI(T1), 25 mm thick bar detector designed for use in positron emission tomography has been studied.
  • (14) In the longitudinal direction, however, spatial resolution of under slice thickness could not be obtained.
  • (15) Thus, multiparae had very thick border zones composed predominantly of large nodules and, additionally, of vacuolated cells and fibrous tissue.
  • (16) The thickness of the media in the groups behaves like the number of nuclei: in hypertension with the highest values, there is no significant decrease as far as the 8th cross-section, while in the coronary sclerosis and third decade groups the values come closer together after the 6th cross-section.
  • (17) A model for left ventricular diastolic mechanics is formulated that takes into account noneligible wall thickness, incompressibility, finite deformation, nonlinear elastic effects, and the known fiber architecture of the ventricular wall.
