Abstract

Ophthalmic complications after tooth extraction are rare but discomforting events. This paper reports the rare complications of a 20-year-old male patient who presented with transient blurring of vision after surgical extraction of several teeth under general anesthesia. Additional diagnostic tests were performed to discern the reason for the pseudomyopia. A literature review was carried out by searching for articles published from 1936 to 2019 using the keywords “dental,” “ophthalmic,” “complication,” “blurring of vision,” and “accommodation disturbance” in PubMed. Only six patients with detailed ophthalmic symptoms similar to those of our patient have been reported. If blurred vision or a myopic shift in refraction is present, pseudomyopia should be suspected, and cycloplegic refraction is essential for diagnosis. The condition improves spontaneously.

  Fig. 1 Extraction of impacted teeth. A. Radiograph obtained before extraction of impacted teeth. Both the maxillary second premolars and third molars were impacted and in contact with the maxillary sinus floor. Both mandibular third molars were impacted and in contact with the inferior alveolar nerve. The left mandibular supernumerary premolar was impacted. B. Surgical extraction of impacted teeth occurred without severe complications.

• 

  Fig. 2 After surgical extraction. A. On the radiograph obtained after surgery, no specific findings existed except perforation of the left maxillary sinus floor. B. According to fat-suppressed T2-weighted magnetic resonance imaging after surgery, edema was present at the extraction sites and right nostril due to nasotracheal intubation, without specific problems around the ocular area. C. Fundus examination showed a normal retina and optic disc.
