Multicenter Study
The Proview phosphene tonometer fails to measure ocular pressure accurately in clinical practice.
To evaluate the Proview Eye Pressure Monitor as a medical instrument and as a technique for enabling a patient to obtain an accurate measure of his or her intraocular pressure (IOP). ⋯ The Proview instrument and technique were reproducible. However, the Proview tonometer seems not to be reliable as an indicator of IOP. The sensitivity for detecting high IOP was low in this cohort, and the agreement with Goldmann applanation was poor for some individuals. This brings into question the underlying assumption that a force proportional to the IOP generates phosphenes.

To determine the association between changes in visual acuity (VA) and frequent falls in older women. ⋯ Loss of vision among elderly women increases the risk of frequent falls. Prevention or correction of visual loss may help reduce the number of future falls.

Comparative Study
Diplopia after cataract surgery: comparative results after topical or regional injection anesthesia.
To compare the incidence of diplopia after topical or regional injection anesthesia in cataract surgery. ⋯ In our study, topical anesthesia was associated with a lower incidence of diplopia relative to regional injection anesthesia. No cases of diplopia secondary to fusion loss or muscle damage were found after topical anesthesia surgery.

To describe the natural history of optic pathway gliomas (OPGs) in patients with neurofibromatosis type 1 (NF1), and to evaluate the current recommended guidelines for monitoring and follow-up of OPGs in this population. ⋯ Contrary to some previous reports, our results show that OPGs in patients with NF1 often present in older children and may progress some time after diagnosis. Given the potential for serious visual consequences, these findings indicate a need for regular ophthalmological monitoring of this population for a long duration.

American Academy of Pediatrics and the American Academy of Ophthalmology strongly recommend protective eyewear for all participants in sports in which there is risk of eye injury. Protective eyewear should be mandatory for athletes who are functionally one-eyed and for athletes whose ophthalmologists recommend eye protection after eye surgery or trauma.
