Optics, Retinoscopy, and Refractometry
The stenopaic slit (alternative spelling: stenopeic) offers a method of performing
refractome- try on an individual with high or irregular astigmatism that may be
present in conditions such as keratoconus. Light along one meridian passes ...

However, where retinoscopy is difficult and high astigmatism is present, the
stenopaic slit (Figure 11.1) may be employed to give a starting point. This trial
case accessory is an elongated pinhole that is used to find an approximate
correction of ...

Clinical Refraction Guide
Chapter Aim Stenopaic slit is used to determine the refractive error in each of the
meridians individually. It is a great help when the patient needs high astigmatic
correction. Test The stenopaic slit consists of rectangular aperture ranging from ...

Certified Ophthalmic Medical Technologist Exam Review Manual
The stenopaic slit might be advantageous to use on a patient with: a) mixed
astigmatism b) keratoconus c) with-the-rule astigmatism d) against-the-rule
astigmatism 2. The first step in using the stenopaic slit is to: a) position the slit b)
enter the ...

correction for the meridian that runs parallel to the stenopaic slit. Record the
power and the meridian on an optical cross. 8. Remove the lens rack from in front
of the ...

For example, de Lapersonne,1 like Wicherkiewicz,1 speaks highly of a stenopaic
hole (as opposed to a stenopaic slit) as a means of improving sight in cases of
conical cornea. Many of his patients, we gather, prefer that means for near-work
to ...

The stenopaic slit and other "old-fashioned" devices may also prove helpful.
Keratometry prior to refractometry may give clues about astigmatism. A
refractometrist needs to be creative to find the optimum correction under less than
optimum ...
The result then of the test by the stenopaic disk is -|- t D. cylinder axis 90° C — 2
D. cylinder axis t80°, thus corroborating the other tests. The stenopaic disk shows
a difference of 3 D. between the two meridians, the refraction of the vertical ...
