Refraction is performed in a semi dark room by using retinoscope
with the examiner at a distance of 0.
15) KC can be detected with simple tools such as an ophthalmoscope or retinoscope
which give 'oil-drop' fundal reflex and 'scissoring'.
In this method, a specific eyedrop is applied to the eyes to relax the focusing muscles, and then refraction is checked after 30-40 minutes using a handheld instrument called a retinoscope
Refractive error was assessed with autorefractometer and retinoscope
prior to visual acuity examination.
Refraction was done with Neitz streak retinoscope
and Topcon auto-refractometer.
All members of this family underwent complete eye examination using the slit lamp, autorefractometer, retinoscope
, ophthalmoscope, glasses box, tonometry and complete cardiac test.
A team comprising of one ophthalmologist and three nursing assistants trained in taking visual acuity (VA), equipped with Snellen's E chart, torches, autorefractometer, trial box, slit lamp, retinoscope
and direct ophthalmoscope (Heine Beta 200) visited the school during working days of week for examination of the students.
Objective refraction was performed with retinoscope
which was followed by subjective refraction till the best corrected visual acuity was achieved.
