What does the root 'SCLER' indicate in relation to the eye?

  1. Pressure

  2. Sclera

  3. Nerve

  4. Light

The correct answer is: Sclera

The root 'SCLER' specifically refers to the sclera, which is the tough, white outer layer of the eyeball. It plays a critical role in protecting the inner components of the eye and providing structural support. The sclera is important for maintaining the shape of the eye and serves as an attachment point for the eye muscles. This anatomical significance is key to understanding various ocular conditions and their treatments, making the connection to 'SCLER' clear in the context of eye anatomy. The other options do not relate directly to the eye: pressure pertains to intraocular pressure, nerves refer to the optical nerve and its functions, and light is associated with vision but not specifically tied to the term 'SCLER.'
