Also known as a ophthalmoscopy, a fundoscopy is a highly intensive medical procedure used to examine the back portion of the eye. The term derives its name from the area of the eye that is examined - the back portion know as the fundus. The fundus area of the eye contains blood vessels, the retina and optical disc making it a very sensitive area to perform any kind of invasive treatment. Arterial narrowing is a common predictive factor in the development of a number of eye related conditions such as glaucoma. There are three types of funduscopy for arterial narrowing, of which all are non invasive procedures.
The first version of the procedure is known as a direct fundoscopy and is performed primarily with a patient in a seated position and a small beam of light is then directed towards the pupil of the eye using the opthalmoscope, which is an instrument that usually consists of a concave mirror that serves to reflect a small light that is located within the instrument. The doctor will simultaneously examine the eye with the help of a monocular eyepiece. The second type of funduscopy is known as an indirect funduscopy and is performed by placing the patient in a semi reclined position after which some drops are placed into the eye to help it dilate. The doctor will then proceed to make sure the eyelids remain open and direct the light that is on his head, into the retina. The third type of fundoscopy is known as slit lamp fundoscopy and involves the patient being paced in a sitting position and the anesthesia being applied to the eyes. One aspect of the procedure that should be kept in mind is the fact that the intensity of the light will cause the eyes to be rather light sensitive for a matter of hours.
Fundoscopy for arterial narrowing is one of the most commonly used examination methods when it comes to making sure that no conditions are developing. Individuals suffering from diabetes will usually require that fundoscopy be performed as regularly as twice a year, depending largely on the severity of the condition. The only major risk involved in this condition is the activities you perform just after it has been completed. Because of the sensitivity of the eyes, only objects that are located in far off distances are likely to be seen clearly.
