venae episclerales
A doctor uses a diagram to point out the venae episclerales in a model of the human eye.
Noun: * Small veins in the sclera near the corneal margin; empty into the anterior ciliary veins: The term "venae episclerales" refers to a network of tiny blood vessels located in the episclera, which is the thin, loose connective tissue layer covering the white part of the eye (the sclera). These veins are situated near the edge of the cornea, the clear front part of the eye. Their primary function is to collect blood and drain it into the larger anterior ciliary veins.
- Noun:
- Ophthalmologists examine the venae episclerales for signs of inflammation or increased pressure.
- In some eye conditions, the venae episclerales may become dilated and more visible.
- Clinical Significance: The appearance and condition of the venae episclerales can be an important diagnostic clue. Their dilation is often associated with conditions like episcleritis (inflammation of the episclera) or elevated intraocular pressure.
- The redness in episcleritis is typically sectoral and involves the venae episclerales.
- Episcleral (adjective): Pertaining to or located on the episclera.
- Episcleral vessels are superficial and blanch with topical phenylephrine.
- Anterior ciliary veins (noun): The larger veins into which the venae episclerales drain.
- Sclera (noun): The white, fibrous outer layer of the eyeball.
- Cornea (noun): The transparent front part of the eye that covers the iris and pupil.
- Episcleral veins: This is a direct English synonym for "venae episclerales."
This is a highly specialized anatomical term used almost exclusively in medical and ophthalmological contexts. It does not have idiomatic meanings or common phrasal verb associations.
