Direct Ophthalmoscope

The diagnostic capabilities are enhanced by the presence of a greater number of beams and filters.input:
output:In order to enhance diagnostic functionality, five beams are employed.input:
output:An additional blue filter that enables the evaluation of corneal scratches.input:
output:
Available with a 2.8V or 3.6V bulb or LED illumination.input:
output:
AA Batteries are compatible with 2.8V models. Rechargeable 3.6V lithium batteries are compatible with 3.6V models; chargers are sold separately.input:
output:
Action that is constructive The maywheel lens control enables the selection of lens powers ranging from +40D to -25D.input:
output:A complete diagnostic capability is achieved through the use of five diagnostic beams.input:
output:Broad-Angle - for comprehensive examination.

Macula - for a more detailed perspective.

Intermediate - facilitating peripheral examination and providing easier access for non-dilated pupils. An ideal choice for pediatrics.

Slit - to ascertain retinal elevations and depressions. Utilized to determine the depth of the anterior chamber.

Fixation Cross - a graticule is projected onto the retina to evaluate eccentric fixation.input:
output:Swing over the filters, "Free," "Green," and "Red."input:
output:Blue Filter - to be employed in conjunction with Fluorescein to evaluate corneal scratches.input:
output:Soft Brow Rest Integral.
