An observational study on the presence of perilimbal conjunctival pigmentation in vernal keratoconjunctivitis

PURPOSE: To evaluate presence of perilimbal pigmentation (PLP) in Indian patients with vernal keratoconjunctivitis (VKC). METHODS: A cross sectional study was conducted from 2019 to 2020 at a tertiary eye care center in Western Maharashtra, India. In this study, 152 cases of VKC were identified. The...

Sumario:PURPOSE: To evaluate presence of perilimbal pigmentation (PLP) in Indian patients with vernal keratoconjunctivitis (VKC). METHODS: A cross sectional study was conducted from 2019 to 2020 at a tertiary eye care center in Western Maharashtra, India. In this study, 152 cases of VKC were identified. The presence, type, color, and extent of PLP were recorded. The incidence of presence of PLP was calculated. Its correlations with severity and duration of VKC were analyzed using Wilcoxon–Mann–Whitney U test and Chi square test. RESULTS: Of 152 cases, 79.61% were males. Mean age at presentation was 11.4 ± 5.6 years. The characteristic PLP was present in 81 cases (53.29%; 95% confidence interval [CI]: 45.03%–61.42%; P < 0.001), of which 15 cases (18.5%) had this pigmentation in all the four quadrants. There was a significant difference between the groups with respect to quadrants involvement in terms of the extent of PLP in clock hours (Χ(2) = 73.85, P < 0.001). However, the extent did not correlate with age (rho = 0.08, P = 0.487), sex (P = 0.115), time since onset in months (rho = 0.03, P = 0.77), duration of VKC and type or color of PLP (P = 0.12). CONCLUSION: Perilimbal pigmentation seems to be a consistent clinical finding seen in a significant number of VKC cases. It may benefit ophthalmologists in treating VKC cases when the palpebral/limbal signs are elusive.
