    Glossary Retina

    The retina is a thin layer of tissue located at the back of the eye that contains light-sensitive cells, which convert light into neural signals for visual processing. While it is primarily associated with vision, the retina's health can indirectly relate to hair loss, as certain systemic conditions affecting the retina, such as diabetes or hypertension, may also influence hair follicle health and hair growth. Key distinguishing characteristics of the retina include its composition of photoreceptor cells (rods and cones) and its role in processing visual information, which is essential for overall sensory perception.
