Retinal diagnostics refers to a range of techniques used to examine the retina, the light-sensitive layer at the back of the eye. These methods help detect various eye conditions, such as diabetic retinopathy, macular degeneration, and glaucoma. Common diagnostic tools include fundus photography, optical coherence tomography (OCT), and fluorescein angiography, which provide detailed images of the retina. These diagnostic procedures are typically performed by ophthalmologists or optometrists and can help monitor the progression of eye diseases. Early detection through retinal diagnostics is crucial for effective treatment and can prevent vision loss in patients with underlying conditions.
