Researchers from Inserm, Université de Bordeaux and Sorbonne Université have published a study showing that, out of a population of older adults, nearly 40 % have a poorly-corrected vision problem (such as nearsightedness, farsightedness and astigmatism) which could be improved by wearing more suitable glasses. These findings have been published in JAMA Ophthalmology.
Vision problems are common in older adults and associated with negative outcomes in terms of health, quality of life and dependency in activities of daily living. Nearsightedness, farsightedness and astigmatism continue to represent major causes of visual impairment even though they can be corrected simply by wearing the right glasses.
Using data from the Alienor cohort, in which more than 700 people aged 78 or over were evaluated, researchers from Inserm, Université de Bordeaux and Sorbonne Université studied the vision problems related to refractive error (such as nearsightedness, farsightedness and astigmatism) and which were uncorrected or poorly corrected by the right glasses or contact lenses.
In addition, nearly 50 % of those examined at home (due to unwillingness or inability to come to the clinic) and 35 % of those with age-related eye disease (age-related macular degeneration, glaucoma…) were estimated to wear unsuitable glasses.
“Beyond the large number of poorly-corrected vision problems in the entire population studied, the yet larger proportion of poor correction in those examined at home should incite prevention strategies aimed specifically at them. Furthermore, the discovery of a large number of poorly-corrected vision problems in people with eye disease – for which they are most often monitored – underlines the need to look out for these unsuitable corrections.” concludes Helmer.
JUMODA, a prospective study sponsored by the Paris public hospitals (AP-HP) and conducted between 2014 and 2015 by teams of researchers and clinicians from Inserm, Université Paris Descartes and AP-HP, has shed new light on the mode of delivering twins. According to ...
A recent study conducted by Inserm researchers within Irset has shown that sustained ibuprofen use in young male athletes induces a hormonal imbalance known as "compensated hypogonadism", usually observed in elderly males. This situation arises due to the negative effects of ibuprofen ...

Virginie Naël, first author of this study, received funding from Essilor International as part of the CIFRE scheme to conduct her doctoral research. This funding fosters the development of public-private partnership research, with the academic research laboratory supervising the doctoral work. Catherine Scherlen, co-author of this study, is an employee of Essilor International. The collection of ophthalmological data from the Alienor cohort was funded mostly by Théa Laboratories.
