    1. Monitoring for glaucoma progression with SAP, electroretinography (PERG and PhNR) and OCT

      Monitoring for glaucoma progression with SAP, electroretinography (PERG and PhNR) and OCT

      Purpose: To investigate the value of pattern electroretinography (PERG) and photopic negative response (PhNR) in monitoring glaucoma compared to standard clinical tests (standard automated perimetry (SAP) and clinical optic disc assessment) and structural measurements using spectral-domain OCT. Methods: A prospective study included 32 subjects (32 eyes) with ocular hypertension, suspect or early glaucoma monitored for progression with clinical examination, SAP, PERG, PhNR and OCT for at least 4 years. Progression was defined clinically by the documented change of the optic disc and/or significant visual field progression (EyeSuite™ trend analysis). One eye per patient was included in the analysis. Results ...

    2. Ganglion cell loss in early glaucoma, as assessed by photopic negative response, pattern electroretinogram, and spectral-domain optical coherence tomography

      Ganglion cell loss in early glaucoma, as assessed by photopic negative response, pattern electroretinogram, and spectral-domain optical coherence tomography

      Purpose To evaluate discrimination ability of pattern electroretinography (PERG) and photopic negative response (PhNR) between early glaucoma and healthy controls, and their relationship with structural measurements using spectral-domain optical coherence tomography (SD-OCT). Methods Cross-sectional study with 34 patients with ocular hypertension ( n = 7), suspect glaucoma ( n = 17), and early glaucoma ( n = 10), plus 24 age-matched controls. The following parameters were analyzed: P50 and N95 amplitude of the PERG, PhNR amplitude and PhNR/b-wave ratio, peripapillary retinal and macular nerve fiber layer (NFL) thicknesses, and ganglion cell complex (GCC) thickness. Data from only one eye per individual were included in the ...

    3. Correlation between nerve fibre layer thickness measured with spectral domain OCT and visual field in patients with different stages of glaucoma

      Correlation between nerve fibre layer thickness measured with spectral domain OCT and visual field in patients with different stages of glaucoma
      Abstract Background  To measure retinal nerve fibre layer (RNFL) thickness with spectral-domain OCT (SD-OCT) in patients with glaucoma, and to evaluate the correlation between visual field parameters and RNFL thickness. Methods  Two hundred twelve subjects—55 normal, 37 with preperimetric glaucoma (PPG) and 119 with different stages of primary open angle glaucoma (POAG) were enrolled in this study. Standard automated perimetry was performed in all eyes. RNFL thickness was measured for 6 segments of the 3.4 mm diameter circle and for 8 areas corresponding to the Early Treatment Diabetic Retinopathy Study (ETDRS) grid, both centred on the optic disc ...
