Abstract
Purpose To simulate modified versions of the 24-2 (6° grid) visual field (VF) test pattern by adding points from the 10-2 (2° grid) test pattern, and to assess their ability to detect early glaucomatous defects in the central 10°.

Importance The macula is essential for visual functioning and is known to be affected even in early glaucoma. However, little is currently understood about the prevalence and nature of central vision loss in early glaucoma. Objective To determine the prevalence and characteristics of visual field (VF) defects in the central 10° in glaucoma suspects and patients with mild glaucoma using a prospective design. Design, Setting, and Participants This prospective observational cohort study was conduct...

Purpose. To better understand the nature of early glaucomatous damage of the macula by comparing the results from 10-2 visual fields, optical coherence tomography (OCT) macular cube scans, and OCT circumpapillary circle scans.

There is a growing body of evidence that early glaucomatous damage involves the macula. The anatomical basis of this damage can be studied using frequency domain optical coherence tomography (fdOCT), by which the local thickness of the retinal nerve fiber layer (RNFL) and local retinal ganglion cell plus inner plexiform (RGC+) layer can be measured. Based upon averaged fdOCT results from healthy controls and patients, we show that: 1. For healthy controls, the average RGC+ layer thickness closel...

Objective To compare loss in sensitivity measured using standard automated perimetry (SAP) with local retinal ganglion cell layer (RGC) thickness measured using frequency-domain optical coherence tomography in the macula of patients with glaucoma. Methods To compare corresponding locations of RGC thickness with total deviation (TD) of 10-2 SAP for 14 patients with glaucoma and 19 controls, an experienced operator hand-corrected automatic segmentation of the combined RGC and inner plexiform layer...

Preserving central vision is of paramount importance in treating glaucoma. However, it is fair to say we know more about paracentral damage than we do about damage to this most important region for visual function. This is in part due to the fact that visual field (VF) damage is commonly assessed with standard automated perimetry (SAP) and the 24-2 test. The 24-2 test pattern has only four points within the central 4.2° (radius) of fixation and only one point within the fovea, which is optional....

Objective To determine which aspects of vision most influence the ability of patients with glaucoma to function. Methods A total of 192 patients with a full range of glaucomatous visual loss were selected from the Glaucoma Service of Wills Eye Institute. Patients were evaluated clinically with standard visual assessments: visual acuity, contrast sensitivity, visual field, stereopsis, the Disc Damage Likelihood Scale, and intraocular pressure. Patients were evaluated objectively using a comprehen...

Typical glaucomatous visual field loss is characterized by arcuate defects, nasal steps, and other patterns corresponding to the course of retinal nerve fibers that respect the nasal horizontal meridian and usually spare the visual field center.1–5 Damage to the immediate paracentral visual field, leading to a so-called split fixation, is usually understood as a sign of advanced loss in cases of end-stage glaucomatous damage.6 In conventional perimetry, rectangular test point arrangements with a...

A novel automated boundary segmentation algorithm is proposed for fast and reliable quantification of nine intra-retinal boundaries in optical coherence tomography (OCT) images. The algorithm employs a two-step segmentation schema based on gradient information in dual scales, utilizing local and complementary global gradient information simultaneously. A shortest path search is applied to optimize the edge selection. The segmentation algorithm was validated with independent manual segmentation a...

Using either 24-2 or 10-2 visual field (VF) testing only is not enough to cover all the various types of glaucomatous VF defects. We investigated the performance of the combined 24-2 and 10-2 perimetry when conducted together and separately using the structure-function relationship. A total of 30 glaucoma patients with isolated peripheral nasal step, 37 patients with isolated paracentral scotoma, and 38 patients with both paracentral and nasal scotoma were included. To create the combined Humphr...

With the advent of spectral-domain optical coherence tomography (SD-OCT), imaging of the posterior segment of the eye can be carried out rapidly at multiple anatomical locations, including the optic nerve head (ONH), circumpapillary retinal nerve fiber layer (cp-RNFL), and macula. There is now ample evidence to support the role of SD-OCT imaging of the macula for detection of early glaucoma. Macular SD-OCT measurements demonstrate high reproducibility, and evidence on its utility for detection o...
