LOSS OF VISION FOLLOWING A DENTAL PROCEDURE- A CASE STUDY

*Mridula V. Amarnath

Abstract

Nowadays intraoral local anaesthesia has been widely used to perform various dental procedures. The complications associated with it are very minimal though some of the commonly seen ocular complications include meiosis, nystagmus, diplopia, ptosis, amaurosis. In our case study a 30 year old female came to eye OPD with complaints of reduced vision. She had undergone a dental procedure which was done under intra oral local anaesthesia one week prior, following which her vision started deteriorating. Though various mechanisms have been suggested for the cause of diminution of vision post intra oral local anaesthesia, the exact aetiology still remains unknown. In our study intravascular injection of epinephrine which led to a cilioretinal artery occlusion could be the possible cause. The patient was followed up regularly and four weeks later she had recovered complete vision successfully.
