PURPOSE: To evaluate changes in the anterior chamber angle after Boston keratoprosthesis (KPro) placement. PATIENTS/ METHODS: Ten patients were serially imaged with anterior segment optical coherence tomography after Boston KPro surgery. Angles were judged to be open or closed in the horizontal axis. RESULTS: Seven of 10 patients had open angles before KPro placement. Within 4 months, 4 of 7 patients developed angle closure. Contact between the iris and the backplate was seen in 3 of these patients. Two of the 4 eyes demonstrated progressive angle closure. Intraocular pressure was elevated in 3 patients postoperatively due to the obstruction of a glaucoma drainage device tube (1 eye) and angle closure (2 eyes). CONCLUSIONS: After Boston KPro surgery, patients must be carefully monitored for the onset or progression of glaucoma. Progressive angle closure can occur after placement of a Boston KPro and may be seen in conjunction with irido-backplate touch.
