Photophobia is an abnormal intolerance to light, which can cause discomfort or even ocular pain. It can result from several causes, including ophthalmological conditions such as keratitis, uveitis, certain retinopathies, and optic neuropathies, which directly affect ocular structures. Neurological disorders, such as migraines, meningitis, or head trauma, may also be causative. Additionally, psychiatric disorders such as anxiety or depression can contribute to the onset of photophobia, highlighting the close links between sensory perception and psychological state. The pathogenesis of photophobia is based on excessive stimulation of neural circuits involved in light modulation and pain perception, with a predominant role of the nociceptive pathway carried by the trigeminal nerve, visual information transmitted by intrinsically photosensitive retinal ganglion cells, and thalamic and cortical relays. Photophobia represents a significant diagnostic challenge, and understanding its mechanisms, along with the precise identification of its cause, is essential to ensure appropriate targeted management.
Introduction. - Glaucoma is a public health problem and is often diagnosed at a late stage. The goal of this study was to determine the sociodemographic and behavioral factors associated with the intention of healthcare workers at the Fada N'Gourma Regional Medical Center to be screened for glaucoma in 2023 according to the theory of planned behavior. Methods. - This was a cross-sectional study using a self-administered questionnaire conducted in December 2023 among healthcare workers at the Fada CHR who were present at the time of the survey. The data collected were analyzed using IBM SPSS Statistic Version 20.0.0.2 software. Results. - Three-hundred and twenty-one healthcare workers were included in the study. The proportion of healthcare workers screened for glaucoma was 14.33%. Perceived behavioral control, family history of glaucoma, level of university education and age over 50 years were the factors significantly associated (P-value < 0.05) with the intention to undergo glaucoma screening. Conclusion. - These results indicate the need to adopt strategies to motivate healthcare workers to screen for glaucoma. (c) 2025 Elsevier Masson SAS.
