    Gonioscopy is performed with the head positioned in the slit lamp (the special microscope used to look at the eyes). After numbing the eye with drops, a special contact lens is placed directly on the eye and a beam of light is used to illuminate the angle. While the eyelids may feel the presence of the lens, there is typically no pain. In this book the author describes in detail the history, construction, and examination potential of the slit lamp. In particular, however, he presents a new approach – videography – that allows the ophthalmologist to document all (!) eye diseases with the slit lamp and a video camera in a practicable, rapid, and affordable manner.

    Basics of slit lamp microscopy The 2 basic parts of the slit lamp biomicroscope are: • The slit lamp (illumination system) • The biomicroscope. The illumination system can be 1. Of the Zeiss type A gonioscopy lens allows light from the angle to exit the eye by eliminating the cornea air interfaceFile Size: 1MB. The second prerequisite for a slit lamp is the viewing system that provides a clear image of the eye and has sufficient magnification for the practitioner to view all structures of the eye. Binocular viewing permits improved judgement of depth. The slit lamp should be capable of a magnification up to at least 40X.

      Answer: Normally, you cannot report a gonioscopy and slit lamp photographs together because Correct Coding Initiative (CCI) edits forbid it. On the other hand, you can report the two services separately using modifier 59 (Distinct procedural service) .   Because the ophthalmologist performed the gonioscopy and the slit lamp photos for different reasons, you can report both procedures but medical necessity must be documented to indicate why both services were necessary on the same site during the same encounter: Link the appropriate iris nevus diagnosis code (, Benign neoplasm of eye; other.

In slit-lamp gonioscopy, the angle seen in the superior part of the temporal mirror is the superior part of the nasal angle. Variable illumination is an advantage of slit-lamp gonioscopy. One can use diffuse illumination (4‑11), focal illumination with a broad beam (4‑12).

Color Atlas of Gonioscopy, by Wallace L.M. Alward, MD, and Reid A. Longmuir, MD, is a brief, but comprehensive, introduction to gonioscopy. Gonioscopy is a visual science, so the greater part of the book is devoted to illustrations of gonioscopic and slit-lamp findings, normal and abnormal.

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. It is used in conjunction with a 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.

Gonioscopy is the main clinical method of assessing the angle. It visualizes the angle through a contact lens at the slit lamp. Various grading schemes categorize eyes on. The Slit Lamp Primer is the complete book on the slit lamp for the ophthalmic and optometric office. Now updated into a second edition, this user-friendly introduction to the slit lamp microscope highlights the instrument's basic parts as well as examination and illumination techniques.

is a service to the profession by the Department of Ophthalmology at the University of Iowa. This site is dedicated to teaching gonioscopy through the use of videography.

It covers the basic examination techniques and more advanced techniques, such as indentation and the corneal wedge. Gonioscopy will help assess the filtration area. A word of caution: Before you instill dilation drops in the patient, perform the van Herick angle assessment at the slit lamp.

If the angle is grade I (less than one fourth visible), then gonioscopy is indicated to assess the angle. Slit lamp gonioscopy • The part that is viewed is degrees away from the mirror that is being used. • Slit lamp beam is focussed on the mirror that shows the angle diametrically opposite to it.

• Image is inverted but not laterally reversed • Illumination and height of slitlamp are reduced so that it doesn’t impinge on the pupil. Slit-lamp examination of wild-type, Six5 +/− and Six5 −/− mice on a Sv background, at 3 and 8 weeks of age, demonstrated the presence of lenticular cataracts.

We graded lens opacities as small, intermediate, or advanced, when they obscured less than 10% 10–50% or greater than 50% of the visual axis, respectively. In contrast, indirect gonioscopy can be performed at a slit lamp. Two Techniques Worth Learning.

A couple of special gonioscopy techniques are particularly useful: • Indentation gonioscopy is a strategy that helps determine whether angle closure is the result of the iris being in apposition (i.e., just touching the angle) or the result of the.

Direct lenses are quite impractical in the optometric clinical setting. In contrast, indirect gonioscopy lenses have a concave contact surface and use a mirror to reflect light from the angle to the observer.

This method of gonioscopy is practical and easy. Gonioscopy The gonioscope is a fine, smooth mirror that is placed on the cornea, cushioned by thick lubricating fluid.

Used in conjunction with the slit-lamp, this enables us to view the anterior chamber angle, where the aqueous humor drains from the front of the eye.

• Slit lamp beam is focused on the mirror that shows the angle diametrically opposite to it. ADVANTAGE • Easier to learn. • Faster to perform. • Requires less instrumentation and space. • Slit lamp provides better optics and lighting.

• Indentation gonioscopy can also be done. Gonioscopy: | | | Gonioscopy | | | | |Inte World Heritage Encyclopedia, the aggregation of the largest online encyclopedias available, and the most definitive. Gonioscopy, the visualisation of the anterior chamber angle, is central to the examination during the initial and subsequent evaluation of a glaucoma patient.

1 In the infirm or immobile patient it can present a challenge to the examining ophthalmologist when patients are unable to position adequately for slit lamp microscopy.

Here we present a valuable technique for indirect gonioscopy Cited by: 1. One of the first challenges of my glaucoma fellowship was mastering gonioscopy and the iridocorneal angle. As you know, there are many indications for performing gonioscopy, including patients potentially at risk for angle closure, determining the cause of intraocular pressure (IOP) elevation in various acute and chronic settings, trauma and examining abnormalities of the iris or iris lesions.Slit-Lamp Biomicroscopy Synonym/acronym: Slit-lamp examination.
