Intermediate-term results of Baerveldt tube shunt surgery with mitomycin C use.

Background And Objective: To study the intermediate-term results of the Baerveldt glaucoma drainage device with adjunctive use of intraoperative mitomycin C.

Patients And Methods: Charts of 243 consecutive patients with advanced glaucoma who had undergone tube shunt surgery between 1992 and 1999 were retrospectively analyzed. A total of 64 patients were eligible for the study.

Posner-Schlossman syndrome and nonarteritic anterior ischemic optic neuropathy.

A 41-year-old woman with acute OD pain and decreased visual acuity presented with anterior uveitis, an intraocular pressure of 56 mm Hg, an open angle, ipsilateral nerve fiber bundle visual field defects, and optic nerve edema. With control of intraocular pressure and uveitis, visual acuity improved to 20/25, visual field defects persisted, and optic disc pallor developed. She has remained stable over 23 months of follow-up.

Effect of cataract and pupil size on image quality with confocal scanning laser ophthalmoscopy.

Objective: To determine the effect of pupil size and cataract on the reproducibility and image quality obtained with confocal scanning laser ophthalmoscopy.

Methods: Three image series were obtained with a confocal scanning laser ophthalmoscope (Heidelberg Retina Tomograph, Heidelberg, Germany) before and after pupillary dilation in each of 39 subjects (8 normal subjects, 5 glaucoma suspects, and 26 patients with glaucoma). The cataract density was measured with both a lens opacity meter and the Lens Opacities Classification System III system.

Asymmetries in the normal short-wavelength visual field: implications for short-wavelength automated perimetry.

Purpose: To quantify short-wavelength sensitivity in normal eyes by hemifield location, eccentricity, and age.

Methods: We measured achromatic and short-wavelength thresholds across visual fields covering a radius of 21 degrees of visual angle in 115 normal eyes in subjects aged 17 to 77 years and out to 30 degrees of eccentricity in an additional 57 eyes in subjects aged 22 to 80 years.

Results: Results indicated significantly greater sensitivity for the inferior visual field compared with the superior field (P = .

Change in optic disk topography after trabeculectomy.

Purpose: To investigate the relationship between optic disk topography and intraocular pressure before and after trabeculectomy with confocal scanning laser ophthalmoscopy.

Methods: The eyes of 49 consecutive patients undergoing trabeculectomy at a university-based glaucoma practice underwent preoperative and postoperative imaging using a confocal scanning laser ophthalmoscope (Heidelberg Retina Tomograph). Three images of one eye of each patient were obtained with a 15-degree field of view.

Ethnic differences in optic nerve head topography.

Purpose: To investigate ethnic differences in optic nerve head topography.

Methods: This is a cross-sectional university-based comparative study of 180 normal subjects (43 African-American, 45 Asian, 48 Hispanic, and 44 white subjects) ages 19-40 years. Optic nerve head parameters including optic disc size, cup-disc ratio, rim area, rim volume, cup volume, and maximal cup depth were measured using a confocal scanning laser ophthalmoscope (Heidelberg Retina Tomograph).
