Morphology

subretinal = retinal (transparent) = sub + retina + al

The prefix 'sub-' meaning 'under' combines directly with the adjective 'retinal' ('of the retina') to yield 'beneath the retina'.

Etymology

Subretinal starts with sub- meaning 'under', as in submarine, and ends with retina, the part at the back of the eye that senses light. So subretinal means 'under the retina', which is why doctors use it to describe something located beneath that layer of the eye.
