Linear Interstitial Keratitis – A Retrospective Chart Review of a Rare Entity

LIK is a recognisable, predominantly anterior stromal, phenotype of interstitial keratitis affecting predominantly younger patients. An immune-stromal process is assumed, but a clear cause could not be established despite extensive testing. Most cases are steroid-responsive but may relapse, supporting slow tapering and consideration of steroid-sparing prophylaxis. Close monitoring is warranted when thinning, neovascularisation, or recurrence is present.
