XiaoYong Liu200 enrolled

Overview

The aim of this study was to investigate the pathogenic role of obesity on blinding eye diseases in a population of severely obese patients with no history of eye diseases, and to verify whether weight loss induced by bariatric surgery may have a protective effect.

This was a pilot, monocentric, prospective, and open label study conducted at First Affiliated Hospital of Jinan Universityreceived.Patients with body mass index ≥ 32.5Kg/m2; or patients with body mass index of 27.5-32.5Kg/m2 and metabolic diseases were consecutively recruited.All participants underwent complete ophthalmological evaluation， Keratograph 5M and optical coherence tomography.Patients who underwent bariatric surgery were evaluated also 3 months, 6 months and 1 year after surgery.

Patients with dementia, Parkinson's disease, Alzheimer's disease, multiple sclerosis or other severe neurological diseases were also excluded since ophthalmologic parameters may be altered in these conditions. 3.
