Abstract

Aim: The aim of the study is to evaluate the effect of bariatric surgery on the retina and choroid in non-diabetic and non-hypertensive patients with morbid obesity using optic coherence tomography (OCT) retrospectively.
Material and Method: Seventy-four eyes of seventy-four patients who have been underwent sleeve gasterectomy for morbid obesity in Balıkesir University Medicine Faculty & February 2019 and November 2020 were evaluated. All participants has a detailed ophthalmologic examination including best-corrected visual acuity (BCVA), intraocular pressure (IOP), slit-lamp biomicroscopy, retinal examination through non-dilated pupil via 90 D fundus lens, the retinal thickness (central, perifoveal, and parafoveal superior/nasal/inferior/temporal quadrants), and choroidal thickness through optic coherence tomography (RTVue XR Avanti, Optovue) in immediate preoperative and postoperative sixth-month. All values were compared.
Results: The macular thickness was increased significantly in all quadrants in postoperative visits (p<0.05). There was no change in choroidal thickness with surgery (p:0.898). The change in BMI was found correlated with the postoperative paranasal macular thickness (R:0.273, p:0.024) and mean macular thickness (R: 0.244, p: 0.045). There was no correlation between preoperative BMI, and preoperative/postoperative macular thickness (p>0.05). The correlation between preoperative BMI and preoperative choroidal thickness was significant (R: 0.416, p<0.05).
Conclusion: In patients with morbid obesity, the retinal thickness increases with an effective BMI change after bariatric surgery while choroidal thickness was not affected. The effective weight loss has a significant effect on retinal structure.
