direct ophthalmoscope

ophthalmoscope /oph·thal·mo·scope/ (of-thal´mo-skōp) an instrument containing a perforated mirror and lenses used to examine the interior of the eye.

direct ophthalmoscope one that produces an upright, or unreversed, image of approximately 15 times magnification.

indirect ophthalmoscope one that produces an inverted, or reversed, direct image of two to five times magnification.

scanning laser ophthalmoscope an instrument for retinal imaging in which the retina is scanned by a low-power laser and the reflected light is used to create a digital image.

An instrument designed to visualize the interior of the eye, with the instrument relatively close to the subject's eye and the observer viewing an upright magnified image.

ophthalmoscope [of-thal´mo-skōp]

an instrument for examining the interior of the eye.

direct ophthalmoscope one that produces an upright, or unreversed, image of approximately 15 times magnification. The direct ophthalmoscope is used to inspect the fundus of the eye, which is the back portion of the interior eyeball. Examination is best carried out in a darkened room. The examiner looks for changes in the color or pigment of the fundus, changes in the caliber and shape of retinal blood vessels, and any abnormalities in the macula lutea, the portion of the retina that receives and analyzes light only from the very center of the visual field. Macular degeneration and opacities of the lens can be seen through direct ophthalmoscopy.

indirect ophthalmoscope one that produces an inverted, or reversed, direct image of two to five times magnification. An indirect ophthalmoscope provides a stronger light source, a specially designed objective lens, and opportunity for stereoscopic inspection of the interior of the eyeball. It is invaluable for diagnosis and treatment of retinal tears, holes, and detachments. The pupils must be fully dilated for satisfactory indirect ophthalmoscopy.

an instrument for examining the interior of the eye. It sends a bright, narrow beam of light through the lens of the eye, and contains a perforated mirror and lenses through which the veterinarian can examine interior parts of the eye. It is helpful in detecting possible disorders of the eyes, as well as disorders of other organs that are reflected in the condition of the eyes.
