To evaluate the efficacy and safety profile of Kahook Dual Blade ab interno trabeculectomy combined with phacoemulsification compared to stand-alone conventional cataract surgery. A single-center longitudinal, randomized controlled trial was conducted. Patients older than 18 years coexisting open-angle glaucoma or ocular hypertension were invited participate. Preoperative postoperative clinical...

PURPOSE To identify and characterize defects using the automated perimetry test in patients with primary congenital glaucoma. METHODS Automated visual fields and charts of 81 eyes (48 patients) with congenital glaucoma were retrospectively analyzed, 15 being normal eyes (group N) and 66 eyes with primary congenital glaucoma (group G). Eyes of group G were grouped in eyes without perimetric ch...

Perimetric testing is used clinically to detect visual field abnormalities and to monitor changes during the course of management. Conventional automated perimetry (CAP), which employs small (0.43 degree) targets (Fig. 1), is hampered by high test-retest variability. Consequently, many tests are required in order to determine whether a patient is stable or progressing. Decreasing test-retest va...

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 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...

With the multifocal technique, visual evoked potentials (VEPs) can be recorded simultaneously from many regions of the visual field in a matter of minutes. Recently, the multifocal visual evoked potential technique (mfVEP) has generated considerable interest, especially among those seeking objective measures of glaucomatous damage. It is well accepted that significant ganglion cell damage can o...
