PURPOSE: To evaluate the prevalence of diplopia in Greece after cataract surgery among diplopia cases.
METHODS: The authors retrospectively reviewed the medical records of 571 patients with diplopia over an 8-year period in order to evaluate the prevalence of diplopia related to cataract surgery. The surgical and anesthetic records were also reviewed. All patients had full orthoptic assessment including prisms with cover test in all gaze positions. The chi-square and cross-tabulation statistical tests were used for statistical analysis.
RESULTS: Thirty-nine cases (6.8%) were having persistent diplopia related to cataract surgery. Type of anesthesia was peribulbar. Hyaluronidase was not used. Thirteen patients were men and 26 were women. Left eyes were involved in 22 cases (56.4%), right in 17 cases (43.6%). Mean age was 72.5 years. Patients were divided into four groups. Group 1 consisted of 29 patients related to surgical trauma due to anesthesia. Group 2 consisted of 7 patients related to pre-existing disorders. Group 3 consisted of 2 patients related to aniseikonia or anisometropia. Group 4 with 1 patient related to macular pathology. Vertical diplopia was mostly noted (28 cases). Twenty-nine patients were corrected with prisms, 9 needed strabismus surgery, and 1 needed both surgery and prisms.
CONCLUSIONS: Cataract surgery is not a common cause of persistent diplopia. However, this report highlights that prevalence of diplopia related to cataract is high among cases of diplopia in general, with diplopia being mostly vertical (p=0.001), affecting females (p=0.006), and being more common in left eyes, although results did not reach statistical significance (p=0.133).
