Dry eye is a multi-factorial disorder that manifests with painful ocular symptoms and visual disturbances, which can only be partly attributed to tear dysfunction. This disorder may also involve neuroplasticity in response to neuronal injury. This review will emphasize the key characteristics of dry eye pain and its pathologic mechanisms, making the argument that a subset of dry eye represents a neuropathic pain disorder of the eye, more appropriately called "burning eye syndrome." ⋯ Dry eye is becoming a major health concern due to its increasing incidence, significant morbidity, and economic burden. Recent evidence suggests that a subset of dry eye may be better represented as a chronic neuropathic pain disorder due to its features of dysesthesia, spontaneous pain, allodynia, and hyperalgesia. Future therapies targeted at the underlying neuroplasticity may yield improved efficacy for patients with this subset of dry eye, which we term "burning eye syndrome."

Randomized Controlled Trial
A Brief Mindfulness Meditation Training Increases Pain Threshold and Accelerates Modulation of Response to Tonic Pain in an Experimental Study.
Research shows that mindfulness meditation (MM) affects pain perception; however, studies have yet to measure patterns of change over time. We examined effects of MM on perception of experimental heat pain using multiple psychophysical indices, including pattern of change in response to tonic painful stimuli. We also tested the potential moderating role of baseline mindfulness. ⋯ A brief MM intervention appears to affect perception of experimental pain both by increasing pain threshold and accelerating modulation of response. Findings may help elucidate mechanisms of MM for chronic pain.

Belief in one's ability to control pain is a significant predictor of health outcomes and is related to improved functional status. The purpose of this study was to introduce a novel formulation of the construct, Perceived Control Over Pain and to test its effects on functional status. ⋯ In minority populations with low income, factors such as perceived control over pain and its effect on the outcome of patient function need to be considered. Improving Perceived Control Over Pain has the potential for improving patients' feelings of life control and purpose or meaning in life, and psychological and physical functioning for adults living with pain.

Observational Study
Improving Trainee Competency and Comfort Level with Needle Driving Using Simulation Training.
To assess whether a combination of lecture and model simulation improves resident competency and comfort level with needle driving for interventional pain medicine procedures. ⋯ Our study demonstrates that simulation training may improve both trainee comfort level and competency with needle driving. After a brief lecture and a 30-minute training session with the simulator, subjective comfort measures and competency measures (more subjects were able to reach the target, vertical and horizontal deviations from the target decreased) were significantly improved. This suggests that simulation may be a helpful tool in teaching needle driving skills.
