Lacrimal passage irrigation in children with Stevens-Johnson syndrome or toxic epidermal necrolysis: a five-year retrospective study

BACKGROUND: To identity the effect of lacrimal system irrigation in the acute stage in children with Stevens-Johnson syndrome (SJS) or toxic epidermal necrolysis (TEN). METHODS: A retrospective review of 39 patients with SJS or TEN from 2012 to 2017 was analyzed. Patients were divided into two subgroups according to whether they received irrigation in the acute stage. The irrigation group included 21 inpatients and the control group included 18 inpatients. The χ2 test was used to compare clinical findings and data in both groups. RESULTS: The rate of lacrimal system obstructions in the chronic stage of SJS or TEN in the irrigation group was significantly lower than in the control group (p < 0.01). A significant difference was also found between the epiphora rates in patients with SJS or TEN in the chronic stage in the two groups (p = 0.047). One of 15 patients with mild dry eyes or without dry eyes in the irrigation group had epiphora, and it affected five of 12 in the control group. The difference between the two groups was significant (p = 0.03). Epiphora in the two patients in the control group was long-term, owing to the disappearance of puncta marks. CONCLUSIONS: Lacrimal system irrigation with dexamethasone drops in the acute stage was a simple way to lessen lacrimal system obstructions and epiphora in patients with SJS or TEN. It should be considered a conventional ocular treatment for SJS or TEN.
