Which finding is NOT a sign of SLK?

• A. Limbal injection
• B. Corneal neovascularization
• C. Papillary hypertrophy
• D. Lid margin telangiectasia

Answer: (D)

The key idea is recognizing the signs that reflect inflammation of the superior bulbar conjunctiva and limbus in Superior Limbic Keratoconjunctivitis. In SLK, you typically see redness and injection focused at the superior limbus, indicating limbal inflammation, and you may also observe corneal neovascularization in the superior cornea from chronic irritation. The upper lid often shows a papillary reaction, or papillary hypertrophy, as part of the lid-conjunctival response to the chronic surface inflammation. Lid margin telangiectasia, however, is more characteristic of chronic blepharitis and Meibomian gland dysfunction, not of SLK. It reflects lid margin vascular changes from lid margin disease rather than the distinctive superior limbal involvement of SLK. So the finding that does not fit SLK is lid margin telangiectasia.
