Eye examination with the aid of a slit lamp. Side view of a slit lamp machine. Cataract in human eye: magnified view seen on examination with the slit lamp. In ophthalmology and optometry, a slit lamp is an instrument consisting of a high-intensity light source that can be focused to shine a thin sheet of light into the eye.
Eye examination with the aid of a slit lamp. Watzke-Allen test is done by projecting a thin line of light over the macula with a slit lamp. [4] A fundus lens or macular lens is used to aim beam of light on the macula. [5] It is best performed in a dilated eye, projecting a slit beam of approximately 100 μm.
The method involves a narrow slit of light from a slit lamp being projected onto the peripheral cornea at an angle of 60⁰ as near as possible to the limbus. The resulting image is a slit that is projected onto the surface of the cornea, the width is then used as a reference for the grading of the angle.

Slit Lamp Examination The slit lamp also allows inspection of all the ocular media, from cornea to vitreous, plus magnified view of eyelids, and other external ocular related structures. Fluorescein staining of the tear film before slit lamp examination may reveal etiologies of the surface of the eye, such as corneal abrasions or keratitis due ...

A slit lamp exam allows a detailed inspection of the conjunctiva and sclera and improves the detection of globe injury. Slit lamp exam findings like decreased anterior chamber depth or damage to posterior chamber structures indicate open-globe injury. [3] A seidel test detects more subtle or partially self-sealing open-globe injuries.
It is a characterized by a breakdown or damage of the epithelium of the cornea in a pinpoint pattern, which can be seen with examination with a slit-lamp. Patients may present with non-specific symptoms such as red eye, tearing, foreign body sensation, photophobia and burning.
