). There were no drug-related adverse local tolerance findings. Other toxicity studies An additional GLP-compliant rabbit ocular toxicity study was conducted to evaluate the effect on corneal endothelium. In this study Omidria was diluted in balanced salt solution to the diluted clinical concentration and administered by intracameral injection into one eye, and vehicle control was injected into the contralateral eye. In this study, eight female New Zealand White rabbits were evaluated by a board-certified (...) veterinary ophthalmologist every four weeks during a 12-week post-dose observation period. At the end of the 12-week post-dose observation period, the ocular tissues were collected for microscopic evaluation by a board-certified veterinary pathologist. No treatment-related effects on the cornea were observed. 2.3.5.

109. Optimal combination of clinical examinations for neurologic prognostication of out-of-hospital cardiac arrest patients. (Abstract)

TTM.We conducted a retrospective analysis of prospectively collected multicentre registry data. All enrolled patients were supposed to undergo pupil light reflex (PLR), corneal reflex (CR), and Glasgow Coma Scale for 7 days after return of spontaneous circulation (ROSC). We investigated the timing of each examination based on the ROSC and rewarming completion times. The primary outcome was poor neurologic outcome (cerebral performance category 3,4, or 5) at 6 months after cardiac arrest.A total

, and the Cochrane Database of Systematic Reviews (January 2013-April 2020) were searched. Sensitivity and false-positive rate (FPR) for each predictor were calculated. Due to heterogeneities in recording times, predictor thresholds, and definition of some predictors, meta-analysis was not performed.Ninety-four studies (30,200 patients) were included. Bilaterally absent pupillary or corneal reflexes after day 4 from ROSC, high blood values of neuron-specific enolase from 24 h after ROSC, absent N20 waves

The proportion of patients that died within two hours of WLST ranged from 67% to 88% across provinces (P = 0.06), and was predicted by deeper coma (P = 0.01), loss of pupillary light or corneal reflexes (P = 0.02), and vasopressor use (P = 0.01).

The earliest time to prognosticate an unfavourable neurological outcome is 72 hours after ROSC, but longer if sedative or paralytic drugs confound the situation. 9 Among predictive factors are the clinical observations of persistent coma, bilateral absent pupillary or corneal reflexes, absent motor and extensor response to pain, presence of myoclonus, absent N20 wave in somato-sensory evoked potentials, high serum values of neurological biomarkers, a marked reduction

of amblyopia, correct misalignment of the eyes, and some people regain binocular vision. For diagnosis: Routine childhood screening may detect a squint but parents often present their child with a 'turning eye'. Clinical tests to confirm the presence of a squint in primary care include general inspection of the eyes, the corneal light reflex test, and cover tests. General clinical assessment is important to detect a serious underlying disorder that may present as a squint. In addition, testing the red (...) reflex can help to exclude rare serious intraocular disease such as retinoblastoma. Any child with a suspected or confirmed squint should be referred to the paediatric eye service for management (urgently if a serious cause is suspected). Treatments that may be offered include: Glasses to correct any refractive error. Occlusion therapy to treat amblyopia. Surgery (or in some cases injection of botulinum toxin) to correct misalignment of eyes. © .

and consequently a target for pain control. Resiniferatoxin (RTX), a potent TRPV1 agonist, produces transient analgesia when injected peripherally by inactivating TRPV1-expressing nerve terminals through excessive calcium influx. The aim of the present study was to evaluate topical RTX as a corneal analgesic. In rat cornea, a single application of RTX dose dependently eliminated or reduced the capsaicin eye wipe response for 3-5 days, with normal nociceptive responses returning by 5-7 days. RTX alone produced (...) a brief but intense noxious response, similar to capsaicin, necessitating pretreatment of the cornea with a local anesthetic. Topical lidocaine, applied prior to RTX, blocks acute nociceptive responses to RTX without impairing the subsequent analgesic effect. Importantly, RTX analgesia (a) did not impair epithelial wound healing, (b) left the blink reflex intact and (c) occurred without detectable histological damage to the cornea. Immunohistochemistry showed that loss of CGRP immunoreactivity
