Lacrimal-Cutaneous Fistula

Clinical Features

• Can be seen externally as a small orifice inferior to the medical canthus
• May be unilateral or bilateral
• May be patient (with tears or discharges pooling or draining on the surrounding skin) or blunt as a blind sac

Management

• In a blind sac fistula, no treatment is required
• In a patent fistula, surgical treatment to obliterate the fistula is necessary to prevent secondary infection
