641. Topical cannabinoid agonist, WIN55,212-2, reduces cornea-evoked trigeminal brainstem activity in the rat. (PubMed)

at the Vi/Vc transition was reduced significantly by topical WIN-2, while activity at the Vc/C1 junction region displayed only minor decreases. These findings were consistent with the hypothesis that CB1 receptors affect the activity of corneal-responsive neurons that preferentially contribute to homeostasis of the anterior eye and/or reflexive aspects of nociception rather than the sensory-discriminative aspects of corneal nociception. (...) Topical cannabinoid agonist, WIN55,212-2, reduces cornea-evoked trigeminal brainstem activity in the rat. Cannabinoids act at receptors on peripheral and central neurons to modulate diverse physiological functions and produce analgesia. Corneal sensory nerves express the CB1 cannabinoid receptor and project to two spatially discrete regions of the lower brainstem, the trigeminal interpolaris/caudalis (Vi/Vc) transition and subnucleus caudalis/upper cervical cord (Vc/C1) junction region

642. Soluble Fas and Fas ligand in human tear fluid after photorefractive keratectomy (PubMed)

Soluble Fas and Fas ligand in human tear fluid after photorefractive keratectomy The Fas-Fas ligand system is thought to be involved in stromal cell apoptosis after corneal wounding. The aim was to measure changes in human tear fluid levels of soluble Fas (sFas) and Fas ligand (sFasL) following myopic photorefractive keratectomy (PRK).Tear samples of 59 patients were collected preoperatively, and 1 or 2 days after PRK. Tear fluid sFas or sFasL concentrations were determined using sandwich (...) = 0.001) postoperatively, and the mean sFasL concentration (299.1 (28.8) ng/l) to 118.7 (15.9) ng/l (p = 0.000). However, the release of both substances increased significantly: sFas from 87.3 (29.4) mU/min to 229.4 (82.9) mU/min (p = 0.002) and sFasL from 1620.6 (226.4) fg/min to 4777.1 (596.1) fg/min (p = 0.000).Both sFas and sFasL are normal constituents of human tears. Despite a decrease in concentrations related to reflex tears, the release of sFas and sFasL increases significantly after excimer

microscopy was precluded by corneal oedema in one eye. In the remaining six eyes, it demonstrated typical changes including pleomorphism, polymegathism, and the presence of guttae appearing as dark bodies, some with a central bright reflex. In all seven eyes, confocal microscopy revealed the presence of round hyporeflective images with an occasional central highlight at the level of the endothelium. Changes in cell morphology and size were readily appreciated.By comparison with specular microscopy (...) Confocal microscopy in cornea guttata and Fuchs' endothelial dystrophy To report the appearances of cornea guttata and Fuchs' endothelial dystrophy from white light confocal microscopy.Seven eyes of four consecutive patients with cornea guttata were prospectively examined. Of the seven eyes, three also had corneal oedema (Fuchs' dystrophy). In vivo white light tandem scanning confocal microscopy was performed in all eyes.

because of their appearance. The child described in this case appears to be unique because his intelligence is normal, and, to our knowledge, this is the first reported case of penetrating keratoplasty after reconstruction of functional eyelids. The principal problems after corneal grafting appear to have been chronic partial exposure due to inadequate lid length and a poor Bell's reflex and the persistence of a rim of vascularized fibrous tissue around the corneal graft. Future reconstructive surgery (...) Reconstruction of the lids of a child with microblepharon and multiple congenital anomalies. The initial stages in the rehabilitation of a male child with severe microblepharon, corneal opacities, bilateral facial clefts, bilateral complete cleft lip and palate, and unilateral syndactyly are described. Review of the literature suggests that severe microblepharon is associated with other craniofacial anomalies, and often the child is stillborn or retarded. Surviving children have been abandoned

646. Thiopental requirements may be increased in children reanesthetized at least one year after recovery from extensive thermal injury. (PubMed)

Thiopental requirements may be increased in children reanesthetized at least one year after recovery from extensive thermal injury. Clinical observations suggested that children long recovered from burn injury required larger doses of thiopental for a smooth anesthetic induction. A prospective randomized study examined children 6-16 yr old, with greater than 15% burn, and more than 1 year after injury, for loss of lid reflex (LR), corneal reflex (CR), and acceptance of the anesthesia mask (AM

anaesthetic parameters were monitored at induction, during surgery, and during recovery. Consciousness was lost more quickly with propofol (p less than 0.05), but the corneal reflex returned more rapidly in group PD (p less than 0.02). The time required for a full return to normal consciousness was identical in both groups. The fall, during induction, and the increase, during recovery, of Pasys were greater in group PD (p less than 0.05 and less than 0.001 respectively). Padia and heart rate were lower

651. Eye care for patients receiving neuromuscular blocking agents or propofol during mechanical ventilation. (PubMed)

Eye care for patients receiving neuromuscular blocking agents or propofol during mechanical ventilation. The presence of a corneal reflex and the ability to maintain eye closure are instrumental in protecting the cornea. Use of neuromuscular blocking agents or propofol can result in impaired eyelid closure and loss of corneal reflex, leading to corneal exposure. The cornea is then at risk for drying, infection, and scarring, which may lead to permanent visual loss.To determine whether applying (...) for the other eye (control eye).Nine patients had evidence of exposure keratitis in the untreated eye, and 2 had corneal abrasions in both the treated and the control eyes. The remaining 39 patients did not have corneal abrasions in either eye. Use of the artificial tear ointment was more effective in preventing corneal exposure than was passive eyelid closure (P = .004).Eye care with a lubricating ointment on a regular, set schedule can effectively reduce the prevalence of corneal abrasions in patients who
