Introduction Angle-closure disease (both primary and secondary) is a spectrum of disorders characterized by iridotrabecular contact obstructing aqueous outflow. Anterior segment imaging plays an important role in understanding the pathophysiology of angle closure, diagnosis, and monitoring the treatment, especially in challenging cases. Indirect gonioscopy, the gold standard for visualizing the...

In conjunctival and corneal diseases, invasion of the corneal substance by vessels is often the forerunner of more serious disease. The study of vessels in detail is of importance in the assessment of such disease processes and, in particular, in following their natural history and response to treatment. Reports of fluorescein angiography of the anterior segment have generally concerned the mic...

Anterior segment ischemia developed in a 62-year-old dysthyroid patient after two-muscle adjustable suture repair of vertical strabismus. Because of a quiescent pulmonary tuberculous focus he was not treated with systemic steroid therapy but rather with hyperbaric oxygen in the controlled environment of our hospital hyperbaric chamber. He tolerated this treatment well, and his acute symptoms al...

Anterior cervical fusion has become a standard of care for numerous pathologic conditions of the cervical spine. However, subsequent development of clinically significant disc disease at levels adjacent to fused discs is a serious long-term complication of this procedure. As more patients live longer after surgery, it is foreseeable that adjacent segment pathology (ASP) will develop in increasi...

A 60-year-old woman developed anterior segment ischemia 1 week after an uneventful pterygium excision in the left eye. Corrected visual acuity fell from 20/20 to 20/200. Ophthalmic examination found keratic precipitates on the corneal endothelium, ++ cells in the aqueous humor, and necrosis of the lower half of the iris with posterior synechiae resulting in a fixed and distorted pupil. On thera...

TOPIC The clinical features and management strategies for varicella-zoster virus (VZV) infections of the cornea, lids, and adnexa. CLINICAL RELEVANCE Herpes zoster ophthalmicus (HZO) can result in a myriad of chronic and recurrent complications that may be sight threatening. Surgical intervention is the mainstay of treatment, and advancements in this area may lessen the complications of HZO i...

PURPOSE To compare the anterior segment indices measured by two Scheimpflug camera machines; Galilei and Pentacam. METHODS In this observational case series, the anterior segment indices of myopic healthy subjects seeking for refractive surgery were measured by Pentacam and Galilei on the same day. Analyzed parameters were anterior and posterior best fit spheres (BFS), axial curvature, true c...
