乙胺丁醇导致视力损害的多焦视网膜电图检查

世界核心医学期刊文摘（眼科学分册） 2005年第11期1卷 25-26页

作者： Behbehani R.S. Affel E.L. Sergott R.C. savino p.j. 曹绪胜 Neuro -Ophthalmology Service Wills Eye Hospital 840 Walnut Street Philadelphia PA 19107 United States Dr.

Aim: To determine the anatomical site and extent of electrophysiological dysfu nction in patients with ethambutol associated visual loss. Methods: A comparativ e case series. Four patients with ethambutol associated visual loss underwent mu ltifocal electroretinography (mERG). Two patients had advanced visual loss while two had early signs of toxicity. The N1-p1, N1, p1 amplitudes, N1, and p1 late ncies were compared to 10 age and sex matched controls. Results: mERG abnormalit ies were detected in the ethambutol treated patients. The N1 amplitude was signi ficantly lower in the ethambutol treated patients than in the control group. Con clusion: Ethambutol is possibly toxic to the retina, and not only the optic nerv e. The multifocal ERG may be of value to diagnose and monitor patients taking et hambutol.

This paper brings out a structured methodology for identifying intervals of communication time-delay where consensus in directed networks of multiple agents with high-order integrator dynamics is achieved. It is built upon the stability analysis of a transformed consensus problem which preserves all the nonzero eigenvalues of the Laplacian matrix of the associated communication topology graph. It is shown that networks of agents with first-order integrator dynamics can be brought to consensus independently of communication delay, on the other hand, for agents with second-order integrator dynamics, the consensus is achieved independently of communication delay only if certain conditions axe satisfied. Conversely, if such conditions axe not satisfied, it is shown how to compute the intervals of communication delay where multiple agents with second-order or higher-order can be brought to consensus. The paper is ended by showing an interesting example of a network of agents with second-order integrator dynamics which is consensable on the first time-delay interval, but as the time-delay increases, it loses consensability on the second time-delay interval, then it becomes consensable again on the third time-delay interval, and finally it does not achieve consensus any more on the fourth time-delay interval. This example shows the importance of analyzing consensus with time-delay in different intervals.
