| 词条 | Duction |
| 释义 |
A duction is an eye movement involving only one eye.[1] There are generally six possible movements depending upon the eye's axis of rotation:
Forced duction testThe forced duction test is performed in order to determine whether the absence of movement of the eye is due to a neurological disorder or a mechanical restriction.[2] The anesthetized conjunctiva is grasped with forceps and an attempt is made to move the eyeball in the direction where the movement is restricted. If a mechanical restriction is present, it will not be possible to induce a passive movement of the eyeball.[3] Notes1. ^Kanski, JJ. Clinical Ophthalmology: A Systematic Approach.
