The recovery of ocular surface after bariatric surgery in morbid obese patients

Abstract

Aim: To evaluate the alterations of the ocular surface in morbid obese patients after bariatric surgery. Material and Method: The morbid obese patients who underwent sleeve gastrectomy surgery between February 2019 and September 2020 at Department of General Surgery in Balıkesir University Medicine Faculty were evaluated were evaluated in preoperative/postoperative 6th month period. The body-mass index (BMI), abdominal circumference (AC), Ocular Surface Disease Index (OSDI) questionnaire, tear osmolarity, Oxford ocular surface staining score, and Schirmer’s test were performed. Preoperative and postoperative values were compared. Results: The study included 68 eyes of 68 patients (33.76±9.85 years). The BCVA was improved from 0.98±0.11 to 1.00, the BMI was changed from 45.11±2.23 to 30.70±4.92 kg/m2 (p<0.05) while AC was decreased from 134.97±6.07 to 109.38±6.26 cm (p<0.05) after surgery. In preoperative and postoperative period, OSDI was 12.33±20.57 and zero, tear osmolarity was 301.89±12.98 and 293.57±15.65 mOsm/L, Oxford grading was 0.42±0.69 and 0.04±0.20, Schirmer’s test was 13.66±7.71 and 19.26±6.48 mm (in all, p<0.05), respectively. The change in BMI was correlated with postoperative tear osmolarity (r:0.251, p: 0.039), and T-BUT (r: -0.254, p: 0.037). In preoperative values, the preoperative BMI was correlated with OSDI scores and corneal staining score (r:0.292, r:0.388; p<0.05 respectively). Conclusion: The decrease in BMI after surgery improves dry-eye disorder. Bariatric surgery is also crucial in the recovery of ocular surface parameters.
