Background SARS-CoV-2 outbreak pushed the Italian government to start a strict lockdown, replacing school attendance with long-distance learning. This caused reduced exposure to sunlight but increased exposure to screens. Vernal keratoconjunctivitis (VKC) is a chronic inflammatory ocular condition in which exposure to light plays a cardinal role. We conducted an online survey to evaluate the impact of screen exposure in children with VKC during the lockdown. Methods We performed a survey-based

Results Mean scores of signs and symptoms increased homogeneously when studying patients exposed to longer screen time. When comparing scores collected in 2019 versus 2020, there was not a significant reduction in clinical manifestations, although the situation differed between the two centres due to geographical differences in sunlight exposure. Conclusion During the lockdown, there was a reduction of sunlight exposure but conversely an increase in the time spent in front of screens that correlated with the worsening of VKC signs symptoms in direct proportion to the hours/day of screen exposure. Our results also showed a statistically significant difference in the relative impact of long-distance learning on VKC clinical manifestations in the different Italian regions.
