Key result
Bariatric weight loss improves retinochoroidal microcirculation and lowers intraocular pressure despite vitamin A deficiency risks.
Why the study?
The effects of bariatric surgery-induced weight loss on ocular functions, including retinochoroidal microcirculation, glaucomatous factors, and eye surface condition, require assessment.
Does bariatric surgery-induced weight loss improve ocular functions in patients undergoing bariatric surgery?
Does bariatric surgery-induced weight loss improve ocular functions in patients undergoing bariatric surgery?
Bariatric surgery-induced weight loss appears to improve retinochoroidal microcirculation and lower intraocular pressure, though effects on other ocular structures remain unclear.
Should not yet change ocular monitoring in bariatric patients; leaves open prospective trials on microcirculation benefits versus vitamin A risks.
Our review aimed to assess the effects of bariatric surgery-induced weight loss on ocular functions. We focused on retinochoroidal microcirculation, glaucomatous factors, and the condition of the eye surface pre- and postoperatively. The review covered 23 articles, including five case reports. Bariatric surgery positively impacts retinochoroidal microcirculation. The arterial perfusion and vascular density improve, venules constrict, and the arteriole-to-venule ratio increases. Weight loss positively correlates with intraocular pressure decrease. The impact of postoperative weight loss on the choroidal thickness (CT) and the retinal nerve fiber layer (RNFL) is still unclear. The correlation between ocular symptoms and hypovitaminosis A needs to be evaluated. Further research is required, especially regarding CT and RNFL, mainly focusing on long-term follow-up.

Krzyżanowska et al. (2023) conducted a review in Obesity. Bariatric surgery vs. Pre-operative baseline or conservative management was evaluated on Ocular parameters (retinochoroidal microcirculation, intraocular pressure, ocular surface). Bariatric surgery-induced weight loss improves retinochoroidal microcirculation and decreases intraocular pressure, though postoperative vitamin A deficiency may lead to ocular complications.
