Glaucoma, as characterized by accelerated retinal ganglion cell (RGC) death and cupping of optic nerve head (ONH), is one of the leading causes of blindness worldwide. Elevated intraocular pressure (IOP) is generally considered as a major risk factor in the pathogenesis of glaucoma. Previous studies showed that glaucoma caused decrease in collagen and elastin density in several ocular tissues, such as lamina cribrosa, peripapillary sclera and cornea, and resulted in reduced elasticity and compliance of these tissues. It is known that estrogen has protective effects against glaucoma, yet the underlying mechanism still remains obscure. Prior researches have provided evidences showing that the estrogen receptors (ERs) express in a variety of the ocular tissues. Estrogen activates the synthesis of collagen fiber and improves the compliance of these tissues. This leads to a reasonable postulation that increased estrogen may result in a higher content of the collagen fibers and enhanced flexibility of the whole eye, which would therefore decrease IOP. Particularly, the increase in the amounts of collagen fibers at lamina cribrosa improves its compliance, which in turn relieves its compression on RGC axons. Therefore, even at the same IOP level, the softening of cribriform foramina yields a more flexible environment for the RGCs to survive. We therefore hypothesize that estrogen at proper dosage can be considered as a potential therapy for glaucoma since it is able to prevent the eye from glaucomatous damage and lower IOP, especially for those menopausal women with glaucoma.

Enhanced recovery following physical activity and exercise-induced muscle damage (EIMD) has become a priority for athletes. Consequently, a number of post-exercise recovery strategies are used, often without scientific evidence of their benefits. Within this framework, the purpose of this study was to test the efficacy of whole body cryotherapy (WBC), far infrared (FIR) or passive (PAS) modalities in hastening muscular recovery within the 48 hours after a simulated trail running race. In 3 non-adjoining weeks, 9 well-trained runners performed 3 repetitions of a simulated trail run on a motorized treadmill, designed to induce muscle damage. Immediately (post), post 24 h, and post 48 h after exercise, all participants tested three different recovery modalities (WBC, FIR, PAS) in a random order over the three separate weeks. Markers of muscle damage (maximal isometric muscle strength, plasma creatine kinase [CK] activity and perceived sensations [i.e. pain, tiredness, well-being]) were recorded before, immediately after (post), post 1 h, post 24 h, and post 48 h after exercise. In all testing sessions, the simulated 48 min trail run induced a similar, significant amount of muscle damage. Maximal muscle strength and perceived sensations were recovered after the first WBC session (post 1 h), while recovery took 24 h with FIR, and was not attained through the PAS recovery modality. No differences in plasma CK activity were recorded between conditions. Three WBC sessions performed within the 48 hours after a damaging running exercise accelerate recovery from EIMD to a greater extent than FIR or PAS modalities.
