title: Severe complication during strabismus surgery.
abstract: METHODS
  A 4-year-old patient, who presented with an immediate orbital haematoma as a result of a subtenon injection of triamcinolone in the trochlear region of the right eye on finishing a surgical procedure for Brown's syndrome. After one week, when it could be examined better, the presence of a cherry red spot was observed due to the embolisation of the central artery of the retina by triamcinolone crystals.
  
  
  CONCLUSIONS
  Triamcinolone is an anti-inflammatory drug currently used in Ophthalmology for the treatment of various conditions. Although exceptional, it has been described that its use may provoke embolisations due to the entry of the steroid into the circulation.
