Bariatric surgery-what the ophthalmologist needs to know

Area of Science:

• Ophthalmology
• Bariatric Surgery
• Nutritional Deficiencies

Background:

• Obesity is a major public health concern, driving increased bariatric surgery rates.
• Bariatric surgery is linked to ophthalmic changes, a growing area of clinical research.
• Understanding post-bariatric complications is crucial for patient care.

Purpose of the Study:

• To review and summarize ophthalmological complications following bariatric surgery.
• To identify potential recommendations for managing these complications.

Main Methods:

• A comprehensive literature search was conducted across multiple databases (PubMed, Cochrane, Medline, Embase, etc.).
• The search focused on identifying ophthalmological complications in patients after bariatric surgery.
• 59 relevant papers were included in the review.

Main Results:

• Nutritional deficiencies (e.g., Vitamin A, thiamine) are common after bariatric surgery, causing issues like corneal ulceration and Wernicke's Encephalopathy.
• Impacts on diabetic retinopathy are noted, though evidence is conflicting.
• Improvements in obesity comorbidities like idiopathic intracranial hypertension, HB_A1C, sleep apnea, and metabolic syndrome are observed.

Conclusions:

• Pre-surgery ophthalmic screening and post-operative monitoring are suggested.
• Continuous analysis of real-world data is needed to establish definitive management pathways.
• Early recognition of ophthalmic complications can improve patient outcomes.
