Direct ophthalmoscopy

Direct ophthalmoscopy is an ophthalmic examination method that allows the doctor to visualize the fundus of the eye (retina, optic disc, and blood vessels) using an ophthalmoscope with direct magnification. It is used for a fast and detailed assessment of the internal structures of the eye.

Indications

• decreased visual acuity
• unexplained headaches
• suspected retinal diseases
• arterial hypertension
• diabetes mellitus
• suspected glaucoma
• eye trauma
• inflammatory eye diseases
• neurological symptoms with possible optic nerve involvement

Procedure

• the examination is performed by an ophthalmologist in a darkened room
• the doctor directs the ophthalmoscope light through the pupil
• examination of the fundus is performed
• if necessary, mydriatic drops are used to dilate the pupil
• the procedure takes a few minutes
• it is non-invasive and painless

Contraindications

• acute inflammatory eye conditions with severe pain
• eyeball injuries (relative contraindication)
• individual intolerance to mydriatic drops

Recovery / restrictions

• no special recovery is required
• temporary blurred vision may occur after mydriatic drops
• increased sensitivity to light
• patients are advised not to drive for a few hours
• wearing sunglasses is recommended
• reduce visual strain until vision normalizes

Advantages

• quick procedure
• high diagnostic value
• non-invasive and painless
• enables early detection of retinal and optic nerve pathologies
• suitable for all ages

It is crucial to remember that the information provided in this section is not intended for self-diagnosis or self-treatment. If you experience any symptoms or disease exacerbation, it is essential to consult a healthcare professional for proper diagnostic testing and evaluation. Only a qualified specialist can provide an accurate diagnosis and determine appropriate treatment. To obtain the most accurate and consistent evaluation of test results, it is recommended to have them performed at the same laboratory. This is because different laboratories may use varying methods and units of measurement for similar tests.
