Research from the Center for Eye Research Australia has potentially found a link between coffee and tea consumption and the thickness of the macular retinal nerve fiber layer. This layer comprises nerve cells that carry visual information. Its thickness is an important indicator of the macula’s health. The macula is a small area in the retina’s center responsible for clear vision, color perception, and the ability to see fine detail.
The study involved over 35,000 participants from the UK Biobank. This biomedical database keeps in-depth genetic and health information of about 500,000 UK participants, who were asked about their daily coffee and tea consumption over the previous year via a touchscreen questionnaire. Participants were grouped based on their consumption, ranging from nondrinkers to those consuming over four cups daily.
Four? That's a good start.
The participants’ macular retinal nerve fiber layer thickness was measured noninvasively using optical coherence tomography. This diagnostic imaging test uses reflected light to produce detailed images and is commonly employed in detecting retinopathy and glaucoma.
The results showed that coffee drinkers had significantly increased macular retinal nerve fiber layer thickness, particularly those drinking two to three cups of coffee daily. But it wasn’t only coffee that provided this benefit.
Tea consumption also increased macular thickness significantly, but only among participants who consumed more than four cups per day.
