Plasma fatty acids and primary open-angle glaucoma in the elderly: the Montrachet population-based study

Area of Science:

• Ophthalmology
• Nutritional Science
• Geriatrics

Background:

• Primary open-angle glaucoma (POAG) is a leading cause of irreversible blindness.
• Investigating metabolic factors like plasma fatty acids (FAs) may reveal novel insights into POAG pathogenesis.
• Understanding these associations is crucial for early detection and intervention in elderly populations.

Purpose of the Study:

• To compare plasma fatty acid (FA) profiles between elderly individuals with and without primary open-angle glaucoma (POAG).
• To identify specific FA patterns associated with POAG in an aging cohort.
• To explore potential links between FAs and glaucoma in older adults.

Main Methods:

• A population-based study included 810 participants aged over 75 years.
• Comprehensive eye examinations and plasma FA analysis using gas chromatography-mass spectrometry were performed.
• Glaucoma status was determined using established international criteria.

Main Results:

• No significant differences in individual plasma FA levels were observed between POAG and control groups.
• A distinct FA pattern, involving specific polyunsaturated (PUFAs), monounsaturated (MUFAs), and saturated FAs, was positively associated with POAG.
• Individuals with higher scores for this FA pattern had a significantly increased likelihood of POAG (OR = 3.09).

Conclusions:

• While isolated plasma FAs do not differ significantly, a specific FA pattern may be linked to POAG in the elderly.
• This finding suggests a potential role for complex FA profiles in glaucoma development.
• Further research is warranted to elucidate the mechanisms underlying this association.
