Limbal Vernal Keratoconjunctivitis (VKC) is one of the known causes of Limbal Stem Cell Deficiency (LCSD)[1] and has recently gained importance because of the long-term implications of chronic limbal inflammation being documented.[2] We report 2 cases from the same family, presenting with features of either end of the spectrum. One was a 11-year-old male with history of recurrent episodes of both eyes (BE) itching and watering. His best-corrected visual acuity (BCVA) in BE was 20/20 with a significant cylinder of -2.5D, for which a baseline pentacam was done to rule out forme fruste keratoconus [Figure 1]. His examination revealed BE upper tarsal papillae with limbal gelatinous nodules [Figure 2], suggestive of active mixed VKC (predominantly limbal), with a normal fundus and intraocular pressure (IOP).

The second case was his grandfather, a 65-year-old male who gave a history of episodes of itching and redness in childhood being treated with topical medications, and whiteness in superior half of cornea since 30 years. He was a known case of glaucoma, under medication, with a currently normal IOP, bilateral cupping of 0.8 and a BCVA RE 20/60, LE 20/30. Examination of BE seemed suggestive of partial LSCD [Figure 3] and old burnt-out VKC with secondary steroid-induced glaucoma.

VKC is multifactorial disease for which a hereditary association has been suggested. No direct genetic associations nor a clear correlation with specific genetic loci has been found, but the role of cytokine gene cluster on chromosome 5q has been questioned.[3] Although VKC is seen more often in patients who have atopic family histories,[4] it is indeed rare to find 2 cases of different generations in the same family, with features of both active limbal VKC and old chronic limbal inflammation leading to LSCD.
