szemfényképezés

Szemfényképezés, commonly known as fundus photography or retinal photography, is a photographic technique used to document the interior of the eye, specifically the retina, optic disc, and blood vessels. This diagnostic tool provides a detailed, high-resolution image of the fundus, allowing for careful examination and comparison over time.

The process involves a specialized camera, often referred to as a fundus camera, which uses bright light to illuminate the eye and capture images. The camera typically employs a flash or a steady light source. In some cases, a fluorescein dye may be injected into the patient's bloodstream before the photography is taken. This dye circulates to the blood vessels in the retina, and as it passes through, it emits fluorescence that is captured by the camera, creating a fluorescein angiography. This specific technique is invaluable for assessing blood flow and identifying leaks or blockages.

Szemfényképezés is a crucial component in the diagnosis and management of numerous eye conditions. It is widely used to detect and monitor diseases such as diabetic retinopathy, macular degeneration, glaucoma, hypertensive retinopathy, and retinal detachments. The images produced serve as a baseline for future comparisons, enabling ophthalmologists to track the progression of a disease or the effectiveness of treatment. It is a non-invasive procedure that is generally well-tolerated by patients and plays a vital role in maintaining ocular health.
