Artificial intelligence for anterior segment diseases: Emerging applications in ophthalmology

British Journal of Ophthalmology, 2020
With the advancement of computational power, refinement of learning algorithms and architectures, and availability of big data, artificial intelligence (AI) technology, particularly with machine learning and deep learning, is paving the way for ...

Toxic Anterior Segment Syndrome

Journal of Cataract and Refractive Surgery, 2006
Toxic anterior segment syndrome (TASS) is a sterile postoperative inflammatory reaction caused by a noninfectious substance that enters the anterior segment, resulting in toxic damage to intraocular tissues. The process typically starts 12 to 48 hours after cataract/anterior segment surgery, is limited to the anterior segment of the eye, is always Gram

Anterior Segment Configuration

Archives of Ophthalmology, 1982
To the Editor. —I was interested in the article entitled "Anterior Segment Configuration Correlated With Shaffer's Grading of Anterior Chamber Angle" by Chan et al in the JanuaryArchives(1981;99:104-107). These authors have measured central and peripheral corneal thickness and central and peripheral anterior chamber depth using attachments 1 and 2 ...

Anterior Segment Fluorophotometry in Acute Anterior Uveitis

Archives of Ophthalmology, 1987
Anterior segment fluorophotometry was used to assess the severity of blood-aqueous barrier disruption in 25 patients with acute anterior uveitis. The results indicated that HLA-B27-positive patients had a more severe inflammation than did HLA-B27-negative patients, which was not discernible when judged by clinical signs and symptoms.

Anterior segment optical coherence tomography: its application in clinical practice and experimental models of disease

Clinical and experimental optometry, 2019
Optical coherence tomography (OCT) provides non‐invasive, high‐resolution in vivo imaging of the ocular surface and anterior segment. Over the years, it has become an essential tool for evaluating the anterior segment of the eye to monitor ocular ...

Xerophthalmia and Anterior Segment Blindness

American Journal of Ophthalmology, 1976
The prevalence of presumed vitamin A-related corneal scars among 5,589 preschool-age Haitian children ranged from 1.2 per 1,000 in the south, to almost 1% in the famine-afflicted north. These scars accounted for at least 45% of all corneal scars, and all bilateral corneal blindness encountered. Most lesions were acquired during the first three years of

Fibrosis in the Anterior Segments of the Eye

Endocrine‚ Metabolic & Immune Disorders-Drug Targets, 2010
The anterior segment of the eye ball, i. e., cornea and conjunctiva, serves as the barrier to the external stimuli. Cornea is transparent and is a "window"of the light sense, while conjunctiva covers the sclera, the main part of the eyeshell. Fibrosis/scarring in cornea potentially impairs vision by the reduction of its transparency and the alteration ...

Advances in anterior segment imaging

Current Opinion in Ophthalmology, 2007
Imaging of the crystalline lens and intraocular lens is becoming increasingly more important to optimize the refractive outcome of cataract surgery, to detect and manage complications and to ascertain advanced intraocular lens performance. This review examines recent advances in anterior segment imaging.The main techniques used for imaging the anterior
