RESUMEN
PURPOSE: To evaluate the effects of COVID-19 lockdown in Italy on the features of Acute Acquired Concomitant Esotropia (AACE). SUBJECTS: Patients of the Polyclinic Hospital of Bari diagnosed with AACE between January 2018 and December 2021, subdivided in pre-lockdown group - diagnosed before March 2020 - and post-lockdown group. METHODS: Medical records were reviewed, and statistical analysis performed. Deviation size was assessed in the 9 cardinal positions of gaze with refractive correction. Wilcoxon test for unpaired samples was used to compare data of age, near maximum deviation and best corrected visual acuity (BCVA) for each eye; Student's t test was used to compare far maximum deviation, difference far/near maximum deviation and spherical equivalent data. Fisher exact test was used to compare subtype cases (Bielschowsky vs Non-Bielschowsky) in the two groups. A p-value lower than 0.05 was considered statistically significant.The primary outcome measure was the difference in AACE subtypes between the two groups. RESULTS: Nineteen patients were included, of which 12 males (63.2%); 7 belong to the pre-lockdown group and 12 to the post-lockdown group. The difference in types between the two groups proved to be statistically significant (p = 0.01977).The differences in the mean of age, right BCVA, right spherical equivalent and mean spherical equivalent between the two groups proved to be statistically significant (p < 0.05). CONCLUSIONS: After the COVID-19 pandemic, the profile of the typical patient with AACE has probably changed, and now it is more probably myopic and elderly than before. Thus, we observed an increase in the Bielschowsky subtype.
