Disorders of perfusion of the anterior segment of the eye
Australian and New Zealand Journal of Ophthalmology, 1996Abstract Background: We have investigated the vascular perfusion of a wide variety of conditions of the anterior segment using fluorescein angiography. Methods: The conditions were classified and findings reported according to the system set out below. Patients underwent full ocular examination.

Laser irradiation of the anterior segment of the eye—Rabbit eyes
Experimental Eye Research, 1968Ruby lasers with power outputs of 230 and 800 m j caused no detectable lesions in the transparent media of the eye but produced marked changes in the iris of pigmented animals. Repeated exposures were required to produce a hole in brown irides but a hole resulted from a single exposure in a blue iris.

Normalizing videos of anterior eye segment surgeries
2014 36th Annual International Conference of the IEEE Engineering in Medicine and Biology Society, 2014Anterior eye segment surgeries are usually video-recorded. If we are able to efficiently analyze surgical videos in real-time, new decision support tools will emerge. The main anatomical landmarks in these videos are the pupil boundaries and the limbus, but segmenting them is challenging due to the variety of colors and textures in the pupil, the iris,

Modelling Transport in the Anterior Segment of the Eye
Optometry and Vision Science, 2004ABSTRACT: Purpose. To model the kinetics of substances, particularly applied substances, in the anterior segment. Methods. A simple computational model was developed to describe portions of the anterior segment. First,

Malformations of the Anterior Segment of the Eye
2012Abstract This chapter covers the clinical aspects of congenital malformations of the cornea, anterior chamber angle and some of those that involve the iris and lens. This grouping is arbitrary. It reflects the anatomic proximity of the involved structures rather than common pathogenetic or embryopathic mechanisms among the different ...

Optical coherence tomography of the anterior segment of the eye
Ophthalmology Clinics of North America, 2004Optical coherence tomography is a versatile tool for visualization and measurement of corneal and anterior segment anatomy. Keratorefractive surgery, anterior chamber biometry, and angle assessment are some of the applications that should benefit from this technology.

Proteomics of pseudoexfoliation materials in the anterior eye segment
2021Pseudoexfoliation syndrome (PEX) is characterized by the production of white extracellular fluffy clumps of microfibrillar material that aggregates in various organs throughout the body but is known to cause disease in the eye. The accumulation of PEX material (PEXM) in the anterior segment ocular structures is believed to cause an increase in ...

VASCULARIZATION OF THE ANTERIOR SEGMENT OF THE EYE
Archives of Ophthalmology, 1933This study developed from observations on a case of exaggerated pinguecula with great vascularization. Such was the aggravated condition of the multiple pingueculae, with the accompanying vascularization, that the entire visible conjunctiva of the palpebral opening on every side was highly congested and discolored so that the patient, a woman of 38 ...

Malformations of the Anterior Segment of the Eye
Abstract This chapter covers the clinical aspects of congenital malformations involving the cornea, anterior chamber, iris and lens. In the past, the categorization and nomenclature of these malformations has developed in an arbitrary fashion, based on the phenotype acquired by careful clinical examination and reflecting ...James E.

PHOTOGRAPHIC MONITORING OF PATHOLOGY OF THE ANTERIOR SEGMENT OF THE EYE
American journal of optometry and archives of American Academy of Optometry, 1970The reasons for monitoring pathological processes of the eye are discussed. The photographic principles and the specific photographic techniques are described. Convenient systems for slide storage and retrieval are also described so that photography may be adopted as an optometric clinical procedure.
