Novel mechanism of decreased iris vasculature density after cosmetic iris implants.

A 25-year-old man presented with decreased vision in both eyes, approximately 4 years following bilateral bright ocular cosmetic iris implantation. On examination, he was found to have bilateral elevated intraocular pressures, anterior chamber cells and flare, chronic peripheral anterior synechiae and significantly reduced endothelial cell counts. Ultrasound biomicroscopy demonstrated compression of the peripheral iris, resulting in synechial angle closure in both eyes.

The Effect of Eye Drop Technique Education in Patients With Glaucoma.

Education about how to administer eye drops may improve a patient's ability to instill his or her eye drops correctly. Our objectives were to (a) document the methods providers use to educate glaucoma patients about eye drop technique; (b) determine whether eye drop technique education varies by provider and patient characteristics; and (c) evaluate whether education predicts improved patient technique. We conducted an 8-month longitudinal study of 279 glaucoma patients and 15 providers in which we recorded on videotape the content of glaucoma office visits at two time points (baseline and 4- to 6-week follow-up) and videotaped patient eye drop technique at three time points (baseline, 4- to 6-week follow-up, and 8-month follow-up).

How glaucoma patient characteristics, self-efficacy and patient-provider communication are associated with eye drop technique.

Objectives: The objective of this study was to examine the extent to which patient characteristics, eye drop technique self-efficacy, and ophthalmologist-patient communication about eye drop administration are associated with glaucoma patients' ability to instil a single drop, have the drop land in the eye, and avoid touching the applicator tip of the medication bottle to the eye or face while self-administering eye drops.

Methods: Glaucoma patients (n = 279) were recruited from six ophthalmology clinics. Medical visits were videotape-recorded.

Ophthalmologist-patient communication, self-efficacy, and glaucoma medication adherence.

Objective: To examine the associations of provider-patient communication, glaucoma medication adherence self-efficacy, and outcome expectations with glaucoma medication adherence.

Design: Prospective, observational cohort study.

Participants: Two hundred seventy-nine patients with glaucoma who were newly prescribed or taking glaucoma medications were recruited at 6 ophthalmology clinics.

Determinants of Self-Reported Barriers to Glaucoma Medicine Administration and Adherence: A Multisite Study.

Background: Many factors influence glaucoma medication adherence. A better understanding of the relationships between health literacy, depressive symptoms, and patient-reported problems in using glaucoma medications may reveal opportunities for intervention that could improve patients' clinical outcomes.

Objective: To examine the relationship between patient characteristics (demographics, health literacy, and depressive symptoms) and patient-reported problems in using glaucoma medications and to assess factors related to patients' self-reported adherence to glaucoma medications.

Nonpenetrating glaucoma surgery.

Nonpenetrating glaucoma surgery continues to evolve and improve. New technical refinements and increased experience among its practitioners have led to improved efficacy and longer duration of filter survival. These refinements include the use of intraoperative and postoperative antimetabolites, adjunctive space-maintaining devices, and postoperative yttrium-aluminum-garnet laser goniopuncture.

Anterior chamber width measurement by high-speed optical coherence tomography.

Objective: To measure anterior chamber (AC) width and other dimensions relevant to the sizing of phakic intraocular lenses (IOLs) with a high-speed optical coherence tomography (OCT) system.

Design: Cross-sectional observational study.

Participants: Both eyes of 20 normal volunteers.
