Summary

Persistent diplopia after cataract surgery is rare, occurring in 0.25% of cases. Retrobulbar block anesthesia is the primary cause, often damaging the inferior rectus muscle.

Area of Science:

  • Ophthalmology
  • Anesthesiology

Background:

  • Persistent diplopia following cataract surgery is a concern.
  • This study investigates anesthesia-related causes of prolonged double vision after this common procedure.

Purpose of the Study:

  • To determine the incidence and clinical features of persistent diplopia linked to anesthesia in cataract surgery patients.
  • To identify specific anesthetic techniques associated with persistent diplopia.

Main Methods:

  • Retrospective review of anesthesia records for 3587 cataract surgeries.
  • Analysis of patients with diplopia lasting over 1 month, specifically those related to anesthesia.

Main Results:

  • Anesthesia-related persistent diplopia occurred in 0.25% of cases (9 out of 3587).

  • Retrobulbar block anesthesia was implicated in 8 cases, with inferior rectus muscle paresis being the most common cause.
  • No cases of persistent diplopia were associated with topical or general anesthesia.

    • Conclusions:

    • Persistent diplopia after cataract surgery can result from anesthesia, particularly retrobulbar block.
    • Direct muscle damage, especially to the inferior rectus, is a likely mechanism. The overall incidence of anesthesia-related diplopia is low (0.25%).
