What's the difference between ophthalmometer and reflect?

Ophthalmometer


Definition:

  • (n.) An instrument devised by Helmholtz for measuring the size of a reflected image on the convex surface of the cornea and lens of the eye, by which their curvature can be ascertained.

Example Sentences:

  • (1) Keratometry with the Javal ophthalmometer showed a mean cornea radius of 8.77 mm.
  • (2) In order to determine the power of intraocular lenses more easily prior to cataract surgery, we compared the results obtained by automatic measurement of the corneal refractive power by the Humphrey Autokeratometer with manually obtained measurements using the Zeiss ophthalmometer.
  • (3) The refraction of the unilateral aphakic patient has been aided by recent improvements in the ophthalmometer.
  • (4) We examined 92 normal eyes using Javal Ophthalmometer and Corneal Analysis System (EyeSys) intending to compare the keratometric readings obtained by these two instruments.
  • (5) The standard was fixated on a face support of ophthalmometers (of the firms "Rodenstock" and "Karl Zeiss") by means of a support providing transference of the standard in two reciprocally perpendicular meridians on the given (5-35) number of grades.
  • (6) To interpret scale readings below 30 dioptres and over 60 dioptres we compiled an extension table, suited to the ophthalmometer of Javal-Schiøtz (Haag-Streit), making use of low-powered minus and plus auxiliary lenses in front of the tube of the instrument.

Reflect


Definition:

  • (v.) To bend back; to give a backwa/d turn to; to throw back; especially, to cause to return after striking upon any surface; as, a mirror reflects rays of light; polished metals reflect heat.
  • (v.) To give back an image or likeness of; to mirror.
  • (v. i.) To throw back light, heat, or the like; to return rays or beams.
  • (v. i.) To be sent back; to rebound as from a surface; to revert; to return.
  • (v. i.) To throw or turn back the thoughts upon anything; to contemplate. Specifically: To attend earnestly to what passes within the mind; to attend to the facts or phenomena of consciousness; to use attention or earnest thought; to meditate; especially, to think in relation to moral truth or rules.
  • (v. i.) To cast reproach; to cause censure or dishonor.

Example Sentences:

  • (1) Since fingernail creatinine (Ncr) reflects serum creatinine (Scr) at the time of nail formation, it has been suggested that Ncr level might represent that of Scr around 4 months previously.
  • (2) We propose that this dependence on coexpression reflects the association between the LTA::STa hybrids and LTB subunits.
  • (3) Following central retinal artery ligation, infarction of the retinal ganglion cells was reflected by a 97 per cent reduction in the radioactively labeled protein within the optic nerve.
  • (4) Based on several previous studies, which demonstrated that sorbitol accumulation in human red blood cells (RBCs) was a function of ambient glucose concentrations, either in vitro or in vivo, our investigations were conducted to determine if RBC sorbitol accumulation would correlate with sorbitol accumulation in lens and nerve tissue of diabetic rats; the effect of sorbinil in reducing sorbitol levels in lens and nerve tissue of diabetic rats would be reflected by changes in RBC sorbitol; and sorbinil would reduce RBC sorbitol in diabetic man.
  • (5) In all groups, there was a fall in labeling index with time reflecting increasing tumor size.
  • (6) Hepatic enzyme elevations were more dramatic after blunt trauma, reflecting greater hepatocellular disruption.
  • (7) This modified endocrine activity in brook trout may reflect adjustment to adverse external ionic conditions.
  • (8) It is concluded that in the mouse model the ability of buspirone to reduce the aversive response to a brightly illuminated area may reflect an anxiolytic action, that the dorsal raphe nucleus may be an important locus of action, and that the effects of buspirone may reflect an interaction at 5-hydroxytryptamine receptors.
  • (9) We assessed changes in brain water content, as reflected by changes in tissue density, during the early recirculation period following severe forebrain ischemia.
  • (10) Many problems at the macroscopic level require clarification of how an animal uses a compartment of suite of muscles and whether morphological differences reflect functional ones.
  • (11) Defibrotide prevents the dramatic fall of creatine phosphokinase activity in the ischemic ventricle: metabolic changes which reflect changes in the cells affected by prolonged ischemia.
  • (12) The combined results suggest that any possible heterogeneity in the L-CAM genes is not reflected in the size of either the mRNA or protein.
  • (13) Rigidly fixing the pubic symphysis stiffened the model and resulted in principal stress patterns that did not reflect trabecular density or orientations as well as those of the deformable pubic symphysis model.
  • (14) It is also a clear sign of our willingness and determination to step up engagement across the whole range of the EU-Turkey relationship to fully reflect the strategic importance of our relations.
