title: [Ocular complications following surgery of chronic suppurative otitis media].
abstract: OBJECTIVE
  To investigate the rarely reported ocular complications following surgery of chronic suppurative otitis media (CSOM) and explore the possible mechanisms.
  
  
  METHODS
  The clinical data of 4,012 cases of CSOM treated with surgery were analyzed retrospectively, including age, sex, operation time, surgical approach, time of ocular symptoms presentation, duration of ocular symptoms, treatment and prognosis.
  
  
  RESULTS
  Among the 4,012 cases, 109 patients (2.72%) developed ocular complication, of which 68.81% (75/109) suffered from blurred vision, 24.77% (27/109) presented only erythema on eyelids or mild periorbital edema, 4.59% (5/109) had erythema on eyelids with periorbital edema, and 1.83% (2/109) complained of periorbital ecchymosis and edema. All of these complications recovered themselves without any sequela.
  
  
  CONCLUSIONS
  Ocular complications following surgery of CSOM are rarely reported. Pre-auricular incision and fascia harvesting, turbulence of venous and lymphatic drainage and preseptal cellulitis might be the risk factors. Blurred vision might be associated with eye injury during surgery and the use of anticholinergic agent.
