Netthinnediagnostikk

Netthinnediagnostikk, or retinal diagnostics, refers to the various methods and techniques used to examine and diagnose conditions affecting the retina. The retina is the light-sensitive tissue lining the back of the eye, responsible for converting light into neural signals that are sent to the brain, enabling vision. Disorders of the retina can lead to significant vision loss, making accurate and timely diagnosis crucial.

Commonly employed diagnostic tools include ophthalmoscopy, where a doctor uses a specialized instrument to look directly at the retina. Optical coherence tomography (OCT) is a non-invasive imaging technique that provides cross-sectional views of the retinal layers, allowing for detailed analysis of its structure and detection of subtle abnormalities. Fundus photography captures images of the retina, which can be used for documentation, comparison over time, and remote consultation. Fluorescein angiography involves injecting a dye into the bloodstream and observing its flow through the retinal blood vessels, helping to identify leaks or blockages. Electroretinography (ERG) measures the electrical response of the retinal cells to light stimulation, assessing the function of different parts of the retina.

These diagnostic procedures are essential for identifying a wide range of retinal diseases, such as diabetic retinopathy, macular degeneration, retinal detachments, glaucoma, and inherited retinal dystrophies. Early detection and accurate diagnosis through netthinnediagnostikk allow for appropriate treatment strategies to be implemented, potentially preserving or improving vision and preventing further progression of the disease.
