Published:April 22, 2022DOI:https://doi.org/10.1016/j.jcjo.2022.03.009

      Abstract

      Objective

      To examine the effect of bariatric surgery on the macular and peripapillary choroid in the late postoperative period in young patients with morbid obesity and compare them with a healthy control group.

      Methods

      This prospective controlled study included 50 eyes of 25 young patients with morbid obesity and 50 eyes of 25 age and sex-matched healthy controls. Sleeve gastrectomy was performed on all patients with obesity. Preoperative and 6-month postoperative macular and peripapillary choroidal thickness, total choroidal area (TCA), luminal area (LA), and choroidal vascularity index (CVI) were performed. Results were compared with healthy controls by using enhanced depth imaging optical coherence tomography.

      Results

      Choroidal thickness and CVI values were smaller in patients with obesity in both macular and peripapillary areas compared with the healthy control group (both p < 0.001). There was a statistically significant increase in the macular and peripapillary choroidal thickness of patients with obesity when the preoperative and the postoperative 6-month values after bariatric surgery were compared (both p < 0.001). Also, it was found that bariatric surgery increased TCA and LA values in the macular and all sectors of peripapillary areas (all p < 0.001), and CVI values in the temporal and nasal peripapillary sectors (p = 0.007, p = 0.012, respectively).

      Conclusions

      Bariatric surgery was found to increase the macular and peripapillary choroidal thickness and the nasal and temporal peripapillary CVI values in young patients with morbid obesity in the late period. To the best of our knowledge, the current study has shown for the first time that bariatric surgery affects peripapillary choroid and CVI values.
