Definition of Ophthalmoscopy
Ophthalmoscopy is a test, which is conducted by the medical professionals in order to examine the inside of the eye such as the retina, optic nerve, lens and other parts with the help of direct ophthalmoscope or indirect ophthalmoscope.
Indirect ophthalmoscope is a type of medical instrument which uses a head lamp tool to shed a beam of light into the eye.
This test is generally done by eye doctors or ophthalmologist.
Direct ophthalmoscopy is a commonly used eye instrument by most of the ophthalmologists and other medical professionals.
The doctor uses a tool the size of a flashlight in order to examine the eye.
The instrument consist a battery-powered light and a concave mirror.
The examiner looks through the single monocular eyepiece into the patient's eye.
This instrument also has a rotating disc of lenses, which allows the doctors to examine the patient's eye at different magnifications and depths.
The doctor also use eye drops into the patient's eye, so that they could enlarge the pupil and to view the patient's eye clearly.
The ophthalmoscope is also used in several other fields of medicine such as hematology for examining cardiovascular disease or cardiology, neurology, medical genetics, rheumatology, neurosurgery, internal medicine, family medicine, geriatrics and pediatrics.
Visualization of the retina is essential in conditions like the effects of diabetes, hypertension and glaucoma and in problems like meningitis/encephalitis and brain tumors that might cause severe intracranial pressure.
Hermann von Helmholtz was the first German physician-scientist to invent this valuable ophthalmoscope instrument in the year1851.
He was born on 31st August, 1821 and died on 8th September 1894.
In the year 1850, he demonstrated the principle of the ophthalmoscope instrument by using a crude machine (glue, microscope glass plates and cardboard).
With the help of this ophthalmoscope, he could place the eye of the observer in the path of the light beam entering and leaving the patient's eye, enabling the patient's retina to be seen clearly.
