Direct ophthalmoscopy: teaching in primary care
The Clinical Teacher, 2015Direct ophthalmoscopy (DO) is an examination technique used to inspect the retina and other structures of a patient ’ s eye. A skilled examiner may perform DO to identify clinical signs in the eye that may signify a sightthreatening disorder such as diabetic retinopathy, glaucoma and neovascular agerelated macular degeneration, or a lifethreatening ...

Mydriatic Solution for Indirect Ophthalmoscopy
Archives of Ophthalmology, 1981To the Editor. —We read with interest the article "Mydriatic Solution for Outpatient Indirect Ophthalmoscopy" in theArchives(1980;98:1572-1574) by Sinclair et al. Their results support our findings reported earlier ( Am J Ophthalmol 1980;89:553-559), which, apparently, the authors did not have the opportunity to see during the processing of their ...

High Magnification Direct Ophthalmoscopy
American Journal of Ophthalmology, 1978The combination of a high minus setting of the ophthalmoscope and an extra positive lens in front of the patient's eye forms a Galilean telescope that increases magnification in direct ophthalmoscopy. The telescope magnification equals the ratio between objective and ocular focal lengths.

Astigmatism correction in direct ophthalmoscopy
Fourth International Conference on Applications of Optics and Photonics, 2019We present experimental data using an artificial eye in order to show how much astigmatism significantly reduces the quality of the retinal images obtained with a panoptic direct ophthalmoscope with two different magnifications (no magnification and a 6x magnifier.

DIRECT OPHTHALMOSCOPY WITH SIMULTANEOUS COLOUR TELEVISION TRANSMISSION
Acta Ophthalmologica, 1979The authors have developed a direct ophthalmoscope with simultaneous television transmission. The ophthalmoscope is used clinically for student as well as postgraduate teaching and for intercollegial discussion of retinal changes which give rise to differential diagnostic difficulties.

Lateral and Longitudinal Magnification in Direct and Indirect Ophthalmoscopy
Archives of Ophthalmology, 1971Object-image relationships in a reduced schematic eye have been considered for both direct and indirect ophthalmoscopy. Certain distorting effects of lateral and longitudinal magnification in ophthalmoscopy have been defined and compared. The model described allows first order evaluation of imagery for both axial and oblique viewing of the patient's ...
