Circumscribed posterior keratoconus.

BACKGROUND: Posterior keratoconus is characterized by an internal protrusion of the posterior corneal surface and associated localized or diffuse stromal thinning. Two cases of circumscribed (localized) posterior keratoconus are presented that are representative of the spectrum of the anomaly. CONCLUSIONS: The clinical and histological appearance of posterior keratoconus and its differential diagnosis from other corneal ectasias and developmental anomalies are reviewed to enable the eye care practitioner to better diagnose and manage this rare anterior segment disorder.

Automated perimetry in the management of glaucoma.

As optometry's role and responsibilities increase, so does our need to understand and utilize new technological advances to aid in our understanding and management of ocular conditions. Automated perimetry represents one such technological improvement that enhances our ability to detect and analyze the visual field changes associated with glaucoma. An understanding of the automated perimeter's abilities and limitations is needed to effectively incorporate it into the management of glaucoma.

Trauma-induced altitudinal hemianopsia.

A 55-year-old Caucasian female presented with bilateral inferior altitudinal visual field defects which resulted from trauma suffered in an automobile accident. In addition, there was a bilateral reduction in visual acuities and bilateral optic disc pallor. Diagnostic and historical data suggested that the primary site of damage was at the occipital cortex. A subsequent bilateral anterior ischemic optic neuropathy process was also thought to have occurred.

Interexaminer reliability of the optic cup to disc ratio assessment.

Previous controlled reliability studies of cup to disc (C/D) ratio estimations may have been biased by lack of criteria for cup determination, small sample size; and/or large interval grouping of collected data. In our study four examiners independently estimated the C/D ratios of 40 patients by direct ophthalmoscopy using a contour criterion for cup determination. Results indicated that 75% of the estimate pairs differed by 0.10 or less. Fewer than 14% of the estimate pairs differed by 0.2 or greater. The results of the study suggest that when examiners use a specified criterion of contour cupping, interexaminer assessment of the C/D ratio estimation is clinically and statistically reliable.

Transient vision loss associated with Barlow's syndrome.

Barlow's syndrome, also known as mitral valve prolapse, is a common and generally benign cardiological condition. Various reports have implicated this syndrome in the precipitation of embolic oculo-ischemic events. A 33-year-old male presented with complaints of unilateral transient vision loss over a six-month period. Auscultation revealed a mid-systolic click and late systolic murmur, classic of Barlow's syndrome. Referral and subsequent echocardiography confirmed the diagnosis. Mitral valve prolapse should be considered in the differential diagnosis of transient vision loss in a young patient.

Contemporary viewpoints on pigmentary glaucoma.

The pigment dispersion syndrome occasionally results in a specific form of open angle glaucoma (pigmentary glaucoma). Recent evidence suggests a mechanical etiology of pigment liberation. Consideration of these etiological factors influences the optometric management of patients with pigment dispersion syndrome and pigmentary glaucoma. A review of anatomical and histological factors as well as a representative case report are presented.
