“…However, despite a significant reduction in weight and an improvement in the circulatory lipid levels, there was no significant effect of bariatric surgery on the ocular surface health in our participants, even in those with pre-existing signs of ocular surface damage. This finding is similar to an earlier report that included pre-and post-operative measurements in different groups of patients [21]. Follow-up was performed 12 months after the procedure, a period of time that is considered appropriate to allow changes in signs and symptoms to occur [37].…”

“…Indeed, it has been shown that patients with a history of bariatric surgery demonstrate abnormal tear film and have a higher risk of developing dry eye [20]. Nevertheless, another study, that performed pre-and post-bariatric surgery measurements in different groups of patients, did not find such an effect [21]. Due to the fact that there is no clarity of the effect of weight-induced surgery on the quality of the ocular surface, the aim of this research was to prospectively assess the direct effect of weight loss (from bariatric surgery) on the tear film and ocular surface in unselected patients with obesity that underwent Roux-en-Y gastric bypass (RYGB) surgery.…”

The aim of the present research was to assess the effect of bariatric surgery-induced weight loss on the tear film and ocular surface of patients with obesity. A total of 29 participants with obesity (aged 47.2 ± 10.1 years, 8 male) were measured at baseline and followed up one year after Roux-en-Y gastric bypass (RYGB) surgery. General anthropometric data, as well as serum lipid markers of cholesterol, were assessed in all individuals. Bilateral anterior eye measurements of tear meniscus height (TMH), non-invasive tear breakup time, bulbar and limbal redness and infrared meibography were captured using the Keratograph K5M (Oculus) and ocular surface damage was evaluated using fluorescein sodium and lissamine green staining. Bariatric surgery resulted in significant loss of weight (body mass index p < 0.001) and an improvement in the blood lipid profile (p < 0.01) in all participants. However, there were no statistically significant differences between the baseline and one-year follow-up for any of the measured clinical ocular surface and tear film variables (all p > 0.05). Although there were trends for a reduced TMH and a decrease in meibomian gland dropout after bariatric surgery, these differences were also insignificant (p > 0.05). In conclusion, weight reduction through bariatric surgery did not have an effect on the tear film or ocular surface in unselected patients with obesity.

“…In previous studies, the OSDI questionnaire was applied to obese patients after bariatric surgery and reported as symptomatic in most of the patients (60.7%) (8). In a prospective study, Marques et al (9) were evaluated 89 obese patients for about 12 months and resulted in no change in OSDI in the postoperative period. In the preoperative period, ocular hyperemia and complaints of a foreign body sensation were reported, but the complaints did not differ after surgery.…”

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

“…However, another study has reported that CT increased in obese children [20]. On the other hand, a recent study reported that all values of the speci ic tests used to evaluate the ocular surface were within the normal range [21]. In some experimental studies, it has been demonstrated that obesity may cause retinal degeneration [22,23].…”
