Electrodiagnostic signs of carpal tunnel syndrome in ocular pseudoexfoliation syndrome.

PURPOSE: To assess the occurrence and severity of electrodiagnostic signs of carpal tunnel syndrome (ED-CTS) in patients with ocular pseudoexfoliation (PEX) and compare them with normal subjects.

METHOD: A cross-sectional study with comparison group was designed and 60 patients with PEX were recruited from May 2019 to February 2021, and the findings were compared with 59 healthy subjects. All patients underwent complete ophthalmologic examination and nerve conduction velocity test at the median nerve was used to assess the occurrence and severity of ED-CTS in both hands.

RESULTS

The mean age of participants was 59.8 ± 4.5 years. Occurrence of ED-CTS was 38.3% in PEX patients and 20.3% in control subjects (P = 0.025). There was also a significant difference in the severityand presence of asymptomatic CTS (P < 0.05). Adjusting other variables, including; age and sex, having severe ED-CTS showed a 3.07fold higher chance in the PEX group (P = 0.005).

CONCLUSION

According to our finding, it seems there is a direct association between PEX and the occurrence, as well as severity of ED-CTS.
