    Micro-invasive Glaucoma Surgery in Childhood Glaucoma
    APR 18, 2019 By Ta Chen Chang MD, Kara M Cavuoto MD
    In adult-onset glaucoma, surgery is offered after conservative therapies have proven inadequate, but in childhood glaucoma, surgery is frequently the first-line treatment. It stands to reason that bleb-less and hardware-free procedures may be particularly suitable for childr…

    Techniques of Slit-Lamp Gonioscopy
    NOV 08, 2017 By Wallace L M Alward MD, Reid A Longmuir MD
    The eye should be examined carefully with the slit lamp before beginning gonioscopy. One might see a prominent Schwalbe’s line, atrophy of the iris, or evidence of previous inflammation, surgery, or trauma.

    Gonioscopic Laser Surgery
    NOV 08, 2017 By Wallace L M Alward MD, Reid A Longmuir MD
    Both laser and incisional surgery are performed with the aid of gonioscopic visualization of the angle. Incisional surgery includes goniotomy, goniosynechialysis, internally created filtration procedures, and internal revisions of filtration fistulas.

    Gonioscopic Grading Systems
    NOV 08, 2017 By Wallace L M Alward MD, Reid A Longmuir MD
    Grading systems permit the recording of gonioscopic findings for communication and for future reference. The three primary alphanumeric systems that are currently used for grading the angle are those of Scheie, Shaffer, and Spaeth.

    The Normal Angle
    NOV 08, 2017 By Wallace L M Alward MD, Reid A Longmuir MD
    The best preparation for recognizing angle pathology is to become familiar with the many variations of normal. Careful gonioscopic evaluation of the anterior segment follows a routine that evaluates all visible structures in a systematic fashion.

    Abnormalities Associated With an Open Angle
    NOV 08, 2017 By Wallace L M Alward MD, Reid A Longmuir MD
    There are no characteristic gonioscopic abnormalities in primary open-angle glaucoma, ocular hypertension, or normal-tension glaucoma. Among the abnormalities that can occur with an open angle are pigment dispersion syndrome, and oculodermal melanocytosis.

    A Brief History of Gonioscopy
    NOV 08, 2017 By Wallace L M Alward MD, Reid A Longmuir MD
    Gonioscopy is a relatively young science, having been developed entirely within the twentieth century. The Greek ophthalmologist Alexios Trantas, who first reported examination of the angle in 1907, viewed the angle in a patient with keratoglobus using a direct ophthalmo…

    Abnormalities Associated With a Closed Angle
    NOV 08, 2017 By Wallace L M Alward MD, Reid A Longmuir MD
    Among the abnormalities associated with a closed angle are pupillary block, plateau iris, aqueous misdirection, and secondary pupillary block, Hyperopic eyes are at highest risk of angle closure; such eyes have shallow anterior chambers and small corneas.

    Anatomy of the Angle
    NOV 08, 2017 By Wallace L M Alward MD, Reid A Longmuir MD
    The purpose of gonioscopy is to permit visualization of the iridocorneal angle (or simply “angle”). Before exploring gonioscopic techniques and findings, it is important to review the anatomy and function of the structures of the angle.

    Developmental Abnormalities of the Angle
    NOV 08, 2017 By Wallace L M Alward MD, Reid A Longmuir MD
    Primary infantile glaucoma results from failure of the angle to develop normally. The diagnosis of infantile glaucoma is usually made when parents notice photophobia with blepharospasm, tearing, cloudy corneas, or large eyes.

    Principles of Gonioscopy
    NOV 08, 2017 By Wallace L M Alward MD, Reid A Longmuir MD
    Viewing the anterior chamber of a normal eye directly is not possible. Light from the junction of the iris and cornea strikes the tear–air interface at a shallow angle, and it is totally reflected back into the eye; this is the principle of total internal reflection.

    Anterior Segment Imaging
    NOV 08, 2017 By Wallace L M Alward MD, Reid A Longmuir MD
    While gonioscopy remains the gold standard by which the angle is evaluated, numerous anterior segment imaging techniques exist to assist in determining anterior segment structure. The two most commonly employed techniques are ultrasound biomicroscopy (UBM) and slit-lamp…

    Color Atlas of Gonioscopy
    NOV 08, 2017 By Wallace L M Alward MD, Reid A Longmuir MD
    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, norm…

    NOV 12, 2015 By Beth Edmunds, MD, PHD, Allison R Loh, MD, Cecilia Fenerty FRCOPHTH MBCHB MD, Maria Papadopoulos MBBS
    Glaucoma may be associated with a variety of predominantly ocular anomalies present at birth. They may or may not be accompanied by systemic features. The risk of glaucoma is lifelong and the assessment of intraocular pressure (IOP) and its effects on the eye must be made th…
