AIM: To investigate the clinical signs of blepharokeratoconjunctivitis (BKC) and evaluate the efficacy of penetrating keratoplasty (PKP) for the disease. METHODS: Sixteen patients (16 eyes) with BKC complicated by corneal perforation hospitalised at Shandong Eye Hospital were retrospectively analyzed. All patients received PKP. Participants were assessed for symptoms, clinical manifestations, the activity and damage grading of BKC. A paired RESULTS: The mean age of the patients was 16.3y. Blurred vision is the most common discomfort, followed by redness, and then photophobia. The duration of ocular discomfort lasted for 3.2y, on average. Three (18.8%) participants were associated with rosacea, while 11 (68.8%) patients had recurrent chalazion or hordeolum. CONCLUSION: BKC combined with corneal perforation occurs mainly among young people with a long history of ocular discomfort. PKP, especially using a minimal graft, is an effective and safe option for treating the disease.
