Central serous chorioretinopathy (CSCR) is a disorder characterized by the serous detachment of the sensory retina in the posterior pole. Although CSCR usually resolves spontaneously, the patients may notice residual visual deficits, despite recovering normal visual acuity. The aim of this study is to compare the blue-on-yellow perimetric parameters with conventional automated perimetric parameters in the detection of visual deficits in patients with resolved CSCR. Eighteen patients who had spontaneous recovered from CSCR were enrolled this study. All subjects were examined twice with each type of perimetry. Wilcoxon test was used for statistical analysis. The achromatic perimetric mean deviation values were significantly higher in patients with CSCR than in the control group, while statistically a significant difference was determined for all of blue-on-yellow perimetric values. In conclusion the loss of central retinal sensitivity remains after resolution of the CSCR even if the visual acuity has recovered to normal. Blue-on-yellow perimetry is more sensitive than achromatic perimetry to reveal this central sensitivity loss.

Purpose: To investigate the diagnostic ability of retinal superficial vasculature evaluation by optic coherence tomography angiography (OCTA) combined with visual field (VF) testing for early primary open-angle glaucoma (POAG).
Patients And Methods: In this cross-sectional study, 84 participants were included, including 11 in the ocular hypertension (OHT) group, 11 in the preperimetric POAG (pre-POAG) group, 29 in the early POAG group and 33 in the control group. All participants underwent 6 × 6 mm scans of macula and optic nerved head by optic coherence tomography (OCT) and OCTA, along with white-on-white and blue-on-yellow VF testing by static automated perimetry.
Pattern electroretinogram, blue-yellow visual evoked potentials and the risk of developing visual field defects in glaucoma suspects: a longitudinal "survival" analysis with a very long follow-up.

Purpose: Estimating glaucoma suspects' risk for visual field defects helps to avoid under- and over-treatment. In this retrospective, longitudinal cohort study with a very long follow-up, we studied whether pattern electroretinograms (PERG) amplitudes and blue-on-yellow visual evoked potential (BY-VEP) latencies can predict visual field defects.
Methods: Participants of the Erlangen Glaucoma Study were examined with PERG and BY-VEP between 9/1991 and 8/2001.

Purpose: To compare the retinal sensitivities between the blue-on-yellow perimetry (BYP)/short-wavelength automated perimetry (SWAP) and green-on-yellow perimetry (GYP) among patients with and without nuclear sclerosis among glaucoma suspects.
Methods: After ophthalmic examination, patients were subjected to two perimetric tests: BYP and GYP. The visual field (VF) parameters were compared between the two perimeters (p < 0.

Background And Aim: In the past, increased latencies of the blue-on-yellow pattern visually evoked potentials (BY-VEP), which predominantly originate in the koniocellular pathway, have proven to be a sensitive biomarker for early glaucoma. However, a complex experimental setup based on an optical bench was necessary to obtain these measurements because computer screens lack sufficient temporal, spatial, spectral, and luminance resolution. Here, we evaluated the diagnostic value of a novel setup based on a commercially available video projector.

Aim: To compare the results of short-wavelength automated perimetry (SWAP) in diabetic patients without retinopathy and healthy subjects and show if it is possible to detect an abnormal function of the retina in diabetic patients before vascular changes on the retina develop. Further, the effect of diabetes duration and long-term glycaemic control on the visual field was examined.
Methods: The study group included 22 patients with diabetes type 1 or 2, without any signs of retinopathy.
