Two cases of keratoconus associated with spontaneous corneal perforation.

We present 2 cases of spontaneous corneal perforation in patients with keratoconus. The first patient developed a corneal scleral fistula 1 year after her initial diagnosis of hydrops. We conclude that adequate eye care education, allergy prophylaxis, and fall precautions may be necessary in patients with keratoconus to prevent corneal perforations. Medical and surgical treatments are both viable first-line treatments for corneal perforations.
