An ophthalmoscope is an indispensable ophthalmology device which provides an accurate and comprehensive fundus examination. To avoid mistakes in a diagnosis and conduct the most effective diagnostic procedures, a doctor has to select high-tech and user-friendly equipment. Exclusively functional ophthalmoscope can cope with all the tasks it is meant for.
Without using an direct ophthalmoscopes, it is difficult to estimate the retina condition, the internal eye environment, including the cornea, the lens, and the vitreous. This device helps a doctor examine patient’s visual abilities. Depending on passing or lateral light rays, an ophthalmologist is able to notice even minor changes in the anterior ocular chamber, iris, cornea, or sclera.
The operation principle of the device is based on illumination, namely special polarized light. Some rays are reflected, and some penetrate the analyzer. After the light reaches the opaque bottom of the eye, it starts depolarizing.
The market offers several types of ophthalmoscopes:
Straight. A thin light beam is directed straight into the eye. The ophthalmology specialist thoroughly examines the place where the light beam strikes. The devices are useful for fundus and cornea examinations. Examinations are conducted directly: one tip of the device is put to the patient’s eye, the other one to the doctor’s eye.
Forehead. They provide an opportunity to carry out complex examinations, ensuring accurate data and making the diagnostic procedures simple and easy.
Binocular. They are based on green, blue, and white light utilization, needing no reflex examinations. They are used for drug-free pupil dilatation.
On the market, runic, mirror, and halogen ophthalmoscopes can be found.
To make the right choice, it is worth focusing on lightweight models. Compact and lightweight devices guarantee maximum comfort to a doctor during examinations. Using such equipment, it is possible to work for longer hours, assessing the patient’s eyes general condition.
There is one more tip: focus on ophthalmoscope modifications with mini-cameras. They will allow not only to conduct examinations but also to show patients their eyes condition. Cameras are connected to a monitor and render all the necessary images.
Autonomous power supply availability is an undoubted advantage for a device to be taken into account when buying ophthalmology equipment.
The prices of some instruments can be as low as 60 USD or less, while the newest, high-tier systems may cost as much as 9000 USD. Well-known brands of ophthalmoscope in the United States are Heine, Keeler and Welch Allyn. Besides, one should understand that new and demo machines will cost more than refurbished or used ones. What is the difference? New machines have never been used. They have the manufacturer’s warranty. Demo machines are, as a rule, exhibition models. They have not been used in clinical practice but they have been often presented at exhibitions. As a result, the direct ophthalmoscope price is lower. Refurbished machines are used machines that have undergone improvements (refurbishment can be done at the manufacturer’s facilities or in private repair shops)
