Abstract Background Existing evidence suggests that visual field defect in eyes with glaucoma significantly varies between individuals. The following study compared the central visual field defects with the peripheral visual field defects in patients with suspect glaucoma and primary open-angle glaucoma (POAG) and investigated whether using the central visual field test alone could result in loss of clinically valuable information. Methods In this prospective observational study, 167 eyes from 89 patients with suspect glaucoma or POAG were first examined with static automated perimetry (SAP), followed by a peripheral visual field test on Octopus 900 perimeter (Haag-Streit, Koeniz, Switzerland). The peripheral visual field test was performed by “Auto Kinetic Perimetry” program, in which Goldmann III4e stimuli randomly moved along 16 vectors at a constant angular velocity of 5 deg/s. Results Glaucomatous peripheral visual field defects were seen in 18% of the eyes with a normal central visual field. In addition, 86% of glaucoma patients with moderate-to-severe central visual field defects had corresponding peripheral visual field defects in the form of localized or diffuse depression of the isopters. Furthermore, a moderate correlation was found between the central and peripheral visual fields. The median test duration was 71 s for the peripheral test and 803 s for the central test (p < 0.001). Conclusions Our study demonstrated the diversity of glaucomatous visual field defects, as well as the possibility of losing the clinically valuable information due to focusing on the central visual field test alone. The peripheral kinetic perimetry is clinically feasible to complement the central static perimetry for a comprehensive assessment of visual function in glaucoma patients.

Purpose: As routine health examinations become more common, many patients first diagnosed with glaucoma have advanced glaucoma. We analyzed the routes to diagnosis and the characteristics of patients initially diagnosed with advanced glaucoma.Methods: We retrospectively retrieved the medical records of patients first diagnosed with advanced glaucoma in our tertiary care center. The inclusion criteria were a mean deviation (MD) less than -12 dB on the visual field test, accompanied by structural damage. All patients were classified in terms of unilateral/bilateral disease, the intraocular pressure before medication, and lens status. We divided patients into those with monocular or binocular advanced glaucoma, high- or normal-pressure glaucoma, and those who were pseudophakic or phakic.Results: We included 73 patients of mean age 69.3 years. The visual field test MD was -19.6 dB. In those with binocular advanced glaucoma, incidental ophthalmic examination was the most common means of diagnosis (52.2%). Central-island visual field defects were the most common defects (54.2%). In those with monocular advanced glaucoma, glaucoma-associated symptoms most commonly triggered diagnosis (46.9%). Both superior and inferiorvisual field defects were the most common defects (42.8%). Glaucoma-associated symptoms were present in 68.2 and 22.8% of patients with high- and normal-pressure glaucoma, respectively. Central-island visual field defects were present in 43.6 and 29.4% of those with high- and normal-pressure glaucoma, respectively.Conclusions: We analyzed the routes to diagnosis and the clinical characteristics of patients with advanced glaucoma. In those with binocular disease, glaucoma was most commonly diagnosed on incidental ophthalmic examination. Central-island visual field defects were the most common defects in patients with binocular and high-pressure glaucoma, and the pseudophakic group. A multi-center longitudinal study on risk factors for delayed glaucoma diagnosis is needed.

Color visual field analysis has proven highly sensitive for early visual impairments diagnosis in MS, yet it has never attained widespread popularity usually because the procedure is difficult to standardize, the devices are costly, and the test is fatiguing. We propose a computerized procedure running on standard PC, cost effective, clonable, and easy handled. Two hundred and sixty-four colored patches subtending 18 angle of vision, with selected hues and low saturation levels are sequentially and randomly displayed on gray equiluminous background of the PC screen subtending 2486408 angle of vision. The subject is requested to press a switch at the perception of the stimulus. The output provides colored maps with quantitative information. Comparison between normals and a selected population of MS patients with no actual luminance visual field defects, showed high statistical difference.
