Conclusion: Moreover, the heterogeneity of design and paucity of studies prompt further investigation in randomized clinical trials. In fact, adequately powered and designed pharmacogenetic association studies are needed to provide body of evidence with good certainty for a more appropriate use of medical therapy in POAG.PROSPERO registration: CRD42023434867.

Conclusion: CONCLUSIONS: Our results suggest that it is possible to address headache-related disability by acting on a set of modifiable factors, with interventions tailored to the specific needs of patients or addressing the exposed populations as a whole. In particular, targeting dietary aspects and exercise is reasonably expected to promote weight loss, and might have an impact on the reduction in fasting plasma glucose and LDL cholesterol, ultimately improving patients’ overall health status and reducing headache-related disability.
PubMed 41437223 ↗Conclusion: The role of the endocannabinoid system in ocular pain is underinvestigated, since only two studies assessing the effects of cannabinoid receptors modulators on pain behavior and other two on pain-related inflammatory processes are found. Preclinical studies investigating the efficacy of cannabinoids in ocular inflammatory and neuropathic pain models are needed to pave the way for clinical translation.
