To evaluate the association between ptergium and pinguecula excision and subsequent improvement in dry eye syndrome.
Seyhan State Hospital, Adana, Turkey
We included 25 consecutive patients with primary nasal ptergium or pinguecula and dry eye symptoms undergoing ocular surgery for the first time from September 2019- January 2020. Our primary outcomes were 2-month postoperative changes in tear film breakup time (TBUT), corneal epithelial fluorescein staining, Schirmer test, OXFORD scale score and OSDI score.
25 eyes from 25 different patients underwent ptergium/ pinguecula excision and conjunctival autografting with using absorbable sutures. The mean age was 38.5 ± 9.4 (range 20-65) years. Mean preoperative TBUT, Schirmer test, and dry eye symptom scores were 4.10 ± 1.25 seconds, 8.07 ± 3.27 mm, and 2.80 ± 0.76 points. Mean postoperative 2 month TBUT, Schirmer test, and dry eye symptom scores were 8.80 ± 1.13 seconds, 8.27 ± 2.02 mm, and 0.25 ± 0.47 points, respectively. The median pre- and postoperative changes were found to be statistically significant by Wilcoxon signed-rank tests for TBUT and dry eye symptom score. Schirmer test score was not found tobe statistically significant. Flurosein staining was shown to be significantly reduced.
The decrease in dry eye symptoms and findings after pterygium/ pinguecula excision is very important for the comfort of patients and the ocular surface.
