Abstract

STUDY DESIGN: A series of two case reports

SUMMARY: Local anesthesia for dental procedures is considered relatively safe since, apart from anaphylactic reactions, only rare complications are reported. Visual disturbances such as diplopia that is presented below account for 0.1% of all complications.
Patients attended the dental clinic for root canal treatment of maxillary posterior teeth. A few minutes immediately after local injection, the patient reported experiencing dizziness, blurred vision, diplopia, and discomfort in her eyelids. Blanching of the face was observed on the patient’s right lateral nasal wall, inferior orbital ridge, and temporal area. All procedures ceased immediately.
We diagnosed the patient with temporary diplopia and Ophthalmologist consultation was done, An ocular function test indicated normal visual activity. Eye was covered with a gauze pad and patient was assured about condition, all symptoms subsided and all areas returned to normal.
