翻訳と辞書　辞書検索 [ 開発暫定版 ] スポンサード リンク Red reflex ： ウィキペディア英語版 Red reflex The red reflex refers to the reddish-orange reflection of light from the eye's retina that is observed when using an ophthalmoscope or retinoscope from approximately 30 cm / 1 foot. This examination is usually performed in a dimly lit or dark room. Many eye problems may be detected by this test, such as: * Cataracts - show leukocoria, or white coloration of the eye which may be from rubella or other maternal infections * Retinoblastoma - shows leukocoria. Newborns are regularly screened for retinoblastomas with an ophthalmoscope. According to ''Bates' Guide to Physical Exams,'' retinal detachment would result in the absence of red reflex in the affected eye. ==Simultaneous red reflex test== The simultaneous red reflex test is used to view both reflexes at the same time. This can help determine if the patient has normal ocular alignment. In order to perform this test the patient and physician are normally approximately 2 to 3 feet away from each other.〔 Pediatric eye exam and disease states, Mara Hover, DO.
