Association between fibromyalgia and cataract: A database retrospective cohort study

Area of Science:

• Rheumatology and Ophthalmology
• Investigating the intersection of systemic autoimmune diseases and ocular health.

Background:

• Fibromyalgia is a chronic disorder characterized by widespread pain and fatigue.
• Cataracts are a leading cause of visual impairment globally, involving clouding of the eye's lens.

Purpose of the Study:

• To determine if fibromyalgia is associated with an increased risk of developing cataracts.
• To quantify the risk of cataract development in individuals diagnosed with fibromyalgia.

Main Methods:

• A case-control study design was employed, comparing fibromyalgia patients (cases) with individuals without a fibromyalgia history (controls).
• Cox proportional-hazards models were utilized to estimate hazard ratios for cataract development.
• Analyses adjusted for potential confounders including age, sex, and comorbidities, with stratification analysis performed for robustness.

Main Results:

• The study included 6,949 participants in both the fibromyalgia and control groups.
• The incidence rate of cataracts was substantially higher in the fibromyalgia group (108.9 per 1000 person-years) compared to the control group (58.9 per 1000 person-years).
• Fibromyalgia patients exhibited a 2.48-fold increased risk (95% CI: 2.34-2.63) of developing cataracts.

Conclusions:

• Fibromyalgia is significantly associated with an elevated risk of cataract development.
• These findings suggest a potential link between fibromyalgia and ocular health, specifically cataract formation.
• Further research may explore underlying mechanisms connecting fibromyalgia and increased cataract risk.
