Association of Retinopathy of Prematurity and Plateau iris.

J Glaucoma 2019 Mar 26. Epub 2019 Mar 26.

Gavin Herbert Eye Institute, University of California, Irvine.

We present a case series describing a unique entity as it relates to plateau iris. There have been many established risk factors for plateau iris, but we present the following cases which describe patients with plateau iris in the setting of prematurity and/or retinopathy of prematurity (ROP) as well as high myopia or emmetropia. We believe this to be a distinct form of plateau iris resulting from abnormal ciliary body and angle development in the preterm infant. Read More

Reliable feature selection for automated angle closure glaucoma mechanism detection.

J Med Syst 2015 Mar 8;39(3):21. Epub 2015 Feb 8.

School of Computer Engineering, Nanyang Technological University (NTU), Singapore, 639798, Singapore,

Glaucoma is an eye disease where a loss of vision occurs as a result of progressive optic nerve damage usually associates with high intraocular pressure. A subtype of glaucoma called primary angle-closure glaucoma (PACG) has been observed to be the result of one or more mechanisms such as Pupil block, Plateau iris, Peripheral iris roll, and Lens in the anterior segment of the eye. Reliable features in anterior segment images are important for determining the specific mechanisms involved in PACG. Read More

Quantitative analysis of iris changes following mydriasis in subjects with different mechanisms of angle closure.

Invest Ophthalmol Vis Sci 2015 Jan 8;56(1):563-70. Epub 2015 Jan 8.

Beijing Tongren Eye Center, Beijing Tongren Hospital, Capital Medical University, Beijing Ophthalmology & Visual Science Key Lab, Beijing, China Beijing Institute of Ophthalmology, Beijing, China.

Purpose: We estimate and compare change in iris cross-sectional area (IA) after physiologic and pharmacologic mydriasis in subjects with different dominant mechanisms for primary angle closure.

Methods: Anterior segment optical coherence tomography (AS-OCT) measurements in light, dark, and following pharmacologic dilation were obtained on primary angle closure suspects (PACS), primary angle closure (PAC), and primary angle closure glaucoma (PACG) examined during the 5-year follow-up of the Handan Eye Study. Subjects were categorized into three subgroups according to their dominant angle closure (AC) mechanisms as determined by AS-OCT: pupillary block (PB), plateau iris configuration (PIC), and thick peripheral iris roll (TPIR).

Cross-Examination for Angle-Closure Glaucoma Feature Detection.

IEEE J Biomed Health Inform 2016 Jan 1;20(1):343-54. Epub 2015 Jan 1.

Effective feature selection plays a vital role in anterior segment imaging for determining the mechanism involved in angle-closure glaucoma (ACG) diagnosis. This research focuses on the use of redundant features for complex disease diagnosis such as ACG using anterior segment optical coherence tomography images. Both supervised [minimum redundancy maximum relevance (MRMR)] and unsupervised [Laplacian score (L-score)] feature selection algorithms have been cross-examined with different ACG mechanisms.

Case-based approach to managing angle closure glaucoma with anterior segment imaging.

Can J Ophthalmol 2014 Dec;49(6):512-8

NYU School of Medicine, New York, N.Y.. Electronic address:

This is a case-based approach to the diagnosis and management of angle closure glaucoma of a variety of causative factors, with a special emphasis on the use of advanced anterior segment imaging including ultrasound biomicroscopy and anterior segment optical coherence tomography. Although all angle closure is caused by iridotrabecular contact, the cause of angle closure glaucoma is classified based on the site of primary blockage of aqueous movement from anterior to posterior: pupillary block, plateau iris, lens-related, and posterior causative factors. Although gonioscopy is traditionally used to visualize the angle structures and estimate the angle width, objective and reproducible measurement of the anterior chamber angle can best be obtained with advanced anterior segment imaging.

Juvenile iridoschisis and incomplete plateau iris configuration.

J Glaucoma 2015 Jun-Jul;24(5):e142-4

Department of Ophthalmology, Weill Cornell Medical Center, New York, NY.

Introduction: Iridoschisis is a rare condition in which there is localized cleavage of the iris stroma into 2 layers. It can be associated with plateau iris and more often with either angle closure or open-angle glaucoma. It usually presents in later life as a bilateral progressive condition, however, in this article we present a young adult with bilateral iridoschisis and incomplete plateau iris configuration.

Intermittent acute angle closure glaucoma and chronic angle closure following topiramate use with plateau iris configuration.

Clin Ophthalmol 2014 17;8:1351-4. Epub 2014 Jul 17.

Department of Ophthalmology, The George Washington University, Washington, DC, USA.

This is a case report describing recurrent intermittent acute angle closure episodes in the setting of topiramate use in a female suffering from migraines. Despite laser peripheral iridotomy placement for the pupillary block component, and the discontinuation of topiramate, the acute angle closure did not resolve in the left eye with chronic angle closure and the patient required urgent trabeculectomy. The right eye responded to laser peripheral iridotomy immediately and further improved after the cessation of topiramate. Read More
