Lower hand grip strength associated with low visual acuity and other ocular parameters of patient: BMJ

2. The presence of nuclear cataract, cortical cataract, subcapsular posterior cataract, open-angle glaucoma, and angle-closure glaucoma were not associated with HGS in the model.

A lower HGS correlated with lower visual acuity, but not with the hearing loss score, the researchers noted, suggesting that vision loss as compared with hearing loss played a more important part in HGS and its associated factors.

In conclusion, a lower HGS is linked to visual impairment, a shorter axial length, a lower intraocular pressure, a thinner layer of nerve fibers in the peripapillary retina, a greater prevalence of diabetic retinopathy, and other factors, including less physical activity, a higher depression score, and worse general health status. 

"Measurement of hand grip strength or a handshake may provide the ophthalmologist additional clinical information about the general health and ocular parameters of the patient," the researchers wrote in their study.
