What causes double vision after injection?

Question: What causes double vision after injection?

I went to have a dental implant today (2nd attempt as the 1st one failed to integrate). Almost immediately when the doctor injected the anesthetic, my left eye started to burn. It felt like it was going to explode. My vision got very blurry and then I suffered double vision which lasted about 25 minutes. When I covered my left eye, everything was normal. When I covered my right eye, no double vision but everything was at a tilt. The dental assistant seemed scared and the dentist left the room after I asked for a few minutes before proceeding. The assistant also seemed concerned about the "white splotches" on my face which the doctor said was a reaction to epinepherine in my sinuses. I seem to be fine now, but would like to know what happened and If I should be concerned. I`ve had lots of dental work and lots of injections and outside of a sugar rush have never had anything like this happen before. Thanks.

Answer: What causes double vision after injection?

Thank you for you question. I presume this was the back of the upper jaw that was anesthetized. This is a recognized complication, although infrequent. The symptoms usually resolve in the time frame for the local anesthetic to wear off, 1 – 6 hours depending on the anesthetic involved.

The eye symptoms are likely due to fibers of the sympathetic nervous system becoming anesthetized and drooping of the eyelid and possibly flushing of the eye would also accompany your symptom complex. The white splotches are the result of the epinephrine constricting the blood vessels in that area. Since the face gets so much collateral (extra) blood supply to most areas, this almost never results in any permanent damage.

complications of dental anesthesia causing double vision

Occular complications following dental local anesthesia

Abstract

Objective: To determine the frequency of appearance and the factors most commonly associated with ocular com-
plications following dental local anesthesia, also establishing the location and type of anesthesia used.
Study Design: An indexed search in the Pubmed and Compludoc databases was carried out with the keywords
“oral anesthesia”, “ocular”, “ophthalmologic”, “damage”, “complications”, “injection”. We established a limitation
that the literature had to have been published after the year 1970. A total of 19 articles were obtained, forming a
total sample of 37 patients. The patient’s sex, age, nerve anesthetized, type of anesthetic used, ophthalmological
complication present, recovery time, treatment and side effects were analyzed.
Results: There is a higher involvement of females (77%). The average age was 34.2 years. There was no preference
for an anesthetic technique. Diplopia was the most common complication (65%), which coincides with the data
from other authors. Almost all of the complications were of a temporary nature, with an average recovery time of
68 minutes.
Conclusions: This is one of the few studies of its kind in dental literature, it thus being difficult to make precise
conclusions. Ophthalmological complications are seldom a problem, diplopia being the most common among
them. The authors appear to indicate an intravascular injection of the anesthetic as the cause of the problem, and
therefore, it should be avoided in order to prevent accidents at the ocular level.
