Slit Lamp Biomicroscopy

Oct biomicroscopy is the use of optical coherence tomography oct in place of slit lamp biomicroscopy to examine the transparent axial tissues of the eye.

Slit lamp biomicroscopy. It is used in conjunction with a biomicroscope the lamp facilitates an examination of the anterior segment and posterior segment of the human eye which includes the eyelid sclera conjunctiva iris natural crystalline lens and cornea. 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. Area of application eyes. The choice of table and stand should also be considered in the selection of a particular instrument.

Description this noninvasive procedure is used to visualize the anterior portion. Traditionally ophthalmic biomicroscopy has been completed with a slit lamp biomicroscope that uses slit beam illumination and an optical microscope to enable stereoscopic magnified cross sectional views of transparent tissues in the eye. The slit lamp beam height can be used to increase the accuracy of disc size estimates when used with appropriate magnification factors garway heath et al. Description this noninvasive procedure is used to visualize the anterior portion.

1 subsequently specular microscopy was added relatively recently as another essential method for evaluation of the endothelium in 2001. The dye absorbs blue light and emits green. The exam is also called biomicroscopy. When you have an eye checkup you will likely undergo a slit lamp exam.

You will usually have the slit lamp exam at an optometry or ophthalmology office. Practitioners will benefit from the slit lamp being mounted on a combi unit which can easily be moved in front of the patient to carry out the examination. Common use to detect abnormalities in the external and anterior eye structures to assist in diagnosing disorders such as corneal injury hemorrhage ulcers and abrasion. Filters used in slit lamp biomicroscopy cobalt blue filter used in conjunction with fluorescein stain dye pods in area where the corneal epithelium is broken or absent.

Area of application eyes. The slit lamp should have a locking device to hold it in position if required. A red free filter and various magnification settings facilitate the assessment of the retinal nerve fibre layer.
