Mutism and neurobehaviour symptoms are well known features, which may occur following surgical excision of mass lesion of various histopathologies in the posterior cranial fossa, during the postoperative period. Mutism may be rarely associated with ataxia of eyelid closure and paresis of external ocular muscles. However, internuclear ophthalmoparesis is not reported in association with mutism f...

This article presents a 6-year-old girl who developed acute unilateral third cranial nerve palsy in the absence of any other sign of central nervous system involvement. Raised titers of immunoglobulin M antibodies against GM1, GD1a, and GD1b ganglioside components were demonstrated. Ten days earlier, the girl had experienced acute gastroenteritis with positive specific immunoglobulin M antibodi...

Ocular misalignment and ophthalmoparesis result in the symptom of binocular diplopia. In the evaluation of diplopia, localization of the ocular motility disorder is the main objective. This requires a systematic approach and knowledge of the ocular motor pathways and actions of the extraocular muscles. This article reviews the components of the ocular motor pathway and presents helpful tools fo...

拝啓 私共の論文「外転眼に注視方向性の粗大な水平性眼振をと もない,中枢神経障害の関与が示唆された急性外眼筋麻痺」 に関し,貴重なご指摘・ご質問をたまわりありがとうござい ました. いただいたコメントでは,「抗 GQ1b 抗体陽性の急性外眼 筋麻痺では中枢神経障害が関与しうる」との私共の主張をご 支持いただくとともに,詳細な神経眼科的診察・検査により 推定障害部位をさらに絞りこめた可能性をご指摘いただいて います. 「本例では輻輳も障害されており内側縦束(MLF)症候群 ではないが」との記述に対し,「論考は成立しない」とご指 摘いただきました.「MLF 症候群」という名称の妥当性につ いては議論のあるところでありますが ,病変部位により規 定されるという立場と症候的に定義されるという立場がある ものと思われます.ご批判の根拠とされている 2 つの論文 2)3) では,核間性の障害でも...

Eye movement disorders may be considered in two categories: those that cause incomplete eye movements (ophthalmoparesis) and those that cause excessive eye movements (saccadic intrusions and nystagmus). Central to an understanding and correct diagnosis of abnormal eye movements is the evaluation of ocular alignment, ocular motility, and each functional class of eye movements: optokinetic, vesti...
