Direct Ophthalmoscopy

Direct ophthalmoscopy (DFO) is a research method that allows you to assess the condition of the fundus. This method is based on the use of a special instrument - an ophthalmoscope, which allows you to view the fundus of the eye through the patient's pupil.

OPV is one of the most common ophthalmoscopy methods, which is used to diagnose various eye diseases, such as glaucoma, diabetic retinopathy, arterial hypertension, etc.

OPV is performed using an ophthalmoscope, which consists of a lighting system and an optical system. The illumination system allows illumination of the fundus of the eye, and the optical system allows it to be viewed through the patient's pupil.

To conduct OPV, the patient is first given eye drops, which dilate the pupil and facilitate the examination. The ophthalmoscope is then placed at a distance of 15-20 cm from the patient's eye, and the doctor begins to examine the fundus.

When performing OPV, the doctor assesses the condition of the vessels of the fundus, the presence of edema, hemorrhages and other changes. The doctor may also use special lenses to improve image quality and provide a more detailed examination of the fundus.

OPV is a safe and non-invasive research method that does not require special patient preparation. However, before performing OPV, it is necessary to consult a doctor and clarify possible contraindications.

Thus, OPV is an effective method for diagnosing fundus diseases, which allows one to assess the condition of blood vessels, the presence of edema and other changes. Regular OPV allows for timely detection of diseases and prevention of complications.
