Relating to or affecting the conjunctiva, the membrane covering the eye; often used in medical contexts.
Formed from conjunctiva plus the adjectival suffix -al. This follows the standard medical pattern of creating adjectives from anatomical nouns to describe things relating to that structure.
You encounter 'conjunctival' most often in eye care—'conjunctival redness' or 'conjunctival infection'—it's the technical way doctors say 'affecting the eye membrane,' and using it shows they're talking about the specific tissue rather than the eye generally.
