Because neurotrophic keratitis represents a sight-threatening complication after trigeminal nerve impairment, Lambiase and colleagues investigated the long-term outcomes of this complication after neurosurgical trigeminal damage. In an observational case series from a corneal diseases referral center in 2010, corneal morphology and function were found to be impaired even years after neurosurgical trigeminal damage.
Because patients often report greater visual difficulties at home than expected from vision testing in the clinic, Bhorade and colleagues compared vision measured at the clinic vs home. In a cross-sectional study conducted from 2005-2009 involving 126 patients with glaucoma and 49 without glaucoma, mean scores for all vision tests were better in the clinic than home for participants with and without glaucoma. Lighting appeared to be the factor most likely associated with differences in vision between the clinic and home. Jeffrey L. Goldberg, MD, PhD, provided a related invited commentary.

Redmond and colleagues evaluated whether frequency-doubling matrix perimetry is more sensitive than standard automated perimetry in identifying visual field worsening in glaucoma. In a longitudinal prospective study, no evidence was found that frequency-doubling matrix perimetry is more sensitive than standard automated perimetry in identifying visual field deterioration. Because the outcome is a single P value individualized to a specific visual field and independent of the scale of the original measurement, this method may be well suited for comparing techniques with different stimuli and scales.
Traumatic brain injury (TBI) is an important cause of morbidity worldwide including visual problems that may affect quality of life. To assess the effect of blast exposure on perceived visual functioning among veterans with TBI, Lemke and colleagues evaluated the 25-item National Eye Institute Visual Functioning Questionnaire and Neuro-Ophthalmic Supplement for utility among 60 inpatients with blast-induced TBI. Individuals with blast-induced TBI reported substantial decrements in their subjective visual experiences.
