As the medical world continues to be transformed by digital technology and increasingly sophisticated instruments that promise more precise and accurate diagnostic features, some things remain unchanged. For ophthalmologists, one of the most basic, yet critical tools used to diagnose eye conditions remains the ophthalmoscope.
In many ways, these tools are better than ever, but proper use still depends on a high degree of competence that comes with training and practice.
Regardless of the model you use, be sure your ophthalmoscope has both a rheostatic control switch that allows you to manually adjust the amount of light emitted and a range of aperture selections. These features give you maximum control over light levels, allowing you to truly customize the tool to suit your individual patients. To ensure you get the most out of your equipment, follow these best practices:
- Eye examinations should take place in a dimly lit room.
- Before the examination begins, conduct a red reflex test. The results of this test may indicate various eye disorders.
- When examining a patient’s left eye, use your left hand. Likewise, when examining a patient’s right eye, use your right hand.
- Examine the optic disk first.
- Following an evaluation of the optic lens, look at the retinal arteries and the four vascular arcades. Doing this helps to position yourself opposite of the eye’s movement.
- Finally, have the patient look directly into the light and examine their macula. This part comes last because for many patients it is the most uncomfortable part of the procedure
The revolutionary PanOptic provides easy entry into the eye, together with a wider field of view to more easily observe conditions such as hypertension, diabetic retinopathy, and papilledema. It’s the newest and has the 5x larger view of the fundus vs. standard ophthalmoscopes in an undilated eye. It also provides 25º field of view vs. the standard 5º field of vi
