SUBRETINAL Meaning and
Definition

Subretinal is an adjective that describes something situated or occurring underneath the retina, which is the innermost layer of the eye responsible for converting light into electrical signals that are transmitted to the brain for visual processing. The term "sub-" indicates a position beneath or below, while "retinal" refers to the retina.
In medical usage, subretinal can refer to various conditions, treatments, or procedures that involve the area beneath the retina. For example, subretinal fluid refers to the presence of abnormal fluid accumulation in the space between the retina and the underlying layers. This can be caused by various eye disorders, such as age-related macular degeneration or retinal detachment.
Subretinal injections or implants are therapeutic techniques in which drugs or devices are inserted into the space beneath the retina to target specific diseases or deliver medication. This approach can be used in gene therapy, where healthy copies of genes are inserted into retinal cells to correct genetic defects.
Overall, the term subretinal is essential within the medical field as it allows for accurate communication and description of conditions, treatments, and procedures related to the space underneath the retina.
