| Gullstrand's slitlamp | In ophthalmology, an instrument consisting of a combination of a microscope and a narrow beam of collimated light that can be narrowed into a slit and used to examine the eye. Synonym: biomicroscope, Gullstrand's slitlamp. (05 Mar 2000) Previous: slippery, slipping patella, slipping rib, slipping rib cartilage, slitNext: slit lamp, slit microscope, slit pores, slit-shellGullstrand's slitlamp -->slit lamp <apparatus, ophthalmology> A special type of examination of the anterior structures of the eye. These include the conjunctiva, sclera, lids, iris, cornea and anterior chamber. The slit lamp is a device which focuses a high intensity light beam (that can be focused as a slit) at the structures of the eye while the examiner looks through a magnifying scope. Eyedrops which numb the eyes and dilate the pupils will often be used prior to examination. The exam is not at all uncomfortable, just time consuming. Diagnoses such as foreign body (to conjunctiva, cornea or sclera), iritis, herpes keratoconjunctivitis, cornmeal ulcer, cataracts, glaucoma and corneal abrasions may be made using this exam. Some foreign bodies can even be removed using the enhanced image amplification of the slit lamp. (19 Jan 1998) |

in strabismus, if the patient is made to turn the head while fixing a distant object, and the corneal reflex of either eye moves in the direction in which the head is turning, then the movement is toward the weaker muscle.
