.. Objectives: To obtain and compare the exact visual status before and after excision of sella supra sellar tumors using the computerized perimetry as a standard measuring tools and then compare with the international studies. Background: Sella suprasellar tumors are though not so common but affect visual acuity of patients and their quality of life drops. These tumors include pituitary adenom...

PURPOSE Vigabatrin can cause retinopathy, resulting in bilateral visual field constriction. Previous analyses of results from a prospective, observational study assessing vigabatrin-induced visual field constriction (described below) employed a partially subjective interpretation of static perimetery. To affirm these previous findings through more objective, quantitative methodology, we now rep...

The present study was aimed to investigate optic nerve involvement by computerized perimetry in 40 (29 women, 11 men) consecutive GO patients not showing definite dysthyroid optic neuropathy (DON). All patients presenting visual acuity defects, pallor or swelling of the optic nerve, concomitant eye disease, evidence of apical crowding or optic nerve stretching at either MRI or CT imaging were e...

OBJECTIVE To determine the effectiveness of scanning laser entoptic perimetry as a noninvasive platform for screening for retinal damage in visually asymptomatic patients within the central 120 degrees (diameter) of vision. DESIGN A masked study comparing entoptic perimetry with fundus photographs. SETTING The Shiley Eye Center and the AIDS Ocular Research Unit at the University of Californ...

PURPOSE To compare conventional structural and functional measures of glaucomatous damage with a new functional measure-contrast sensitivity perimetry (CSP-2). METHODS One eye each was tested for 51 patients with glaucoma and 62 age-similar control subjects using CSP-2, size III 24-2 conventional automated perimetry (CAP), 24-2 frequency-doubling perimetry (FDP), and retinal nerve fiber layer...

PURPOSE To compare directly the robustness of standard automated perimetry (SAP), short-wavelength automated perimetry (SWAP), frequency-doubling perimetry (FDP), and grating-resolution perimetry (GRP) stimuli to different degrees of intraocular stray light induced by commercially available opacity-containing filters. METHODS Five white opacity filters of increasing density were used to simul...

PURPOSE To determine the intraindividual and interindividual characteristics of normal sensitivity derived by short-wavelength automated perimetry (SWAP) as a function of threshold algorithm. To determine also the influence of ocular media absorption on the magnitude of the interindividual variation in normal sensitivity, and hence the confidence limits, derived by SWAP. METHODS The sample co...

Purpose To test whether quantitative functional tests and optical coherence tomography (OCT)-defined structure can serve as effective tools to diagnose and monitor early diabetic neuroretinal disease. Methods Fifty-seven subjects with diabetes (23 without diabetic retinopathy [no DR], 19 with mild nonproliferative diabetic retinopathy [mild NPDR], 15 with moderate to severe [moderate NPDR]), ...
