Psychophysical scores on elementary visual function tests and UFOV test of subjects included in the analyses.
<p>Psychophysical scores on elementary visual function tests and UFOV test of subjects included in the analyses.</p
Scatterplots of UFOV scores as a function of age.
Presentation time required to respond 75% correct on the (A) first subtest, where subjects indicate which of two figures was presented, (B) second subtest, where subjects indicate which of two figures was presented in the center and where another stimulus was shown in the periphery and (C) third subtest, where the task is similar as for subtest two, but the stimuli are surrounded by distractors, of the commercially available UFOV test. Lines represent the linear predictive effect of age on UFOV subtest scores (UFOV ∼ β0 + β1 * agec). UFOV = Useful Field of View.</p

Example fundus photos and OCT scans of the left eye of a typical participant.
<p>Images were made of the posterior pole and optic disc and nerve for each eye.</p
Estimated standardized effect sizes (β’) of age<sub>c</sub> and age<sub>c</sub><sup>2</sup>.
<p>The black and grey filled circles and their 95% confidence intervals represent the standardized estimates of the effects of age<sub>c</sub> and age<sub>c</sub><sup>2</sup> in the linear and quadratic regression models, respectively. The open circles represent the standardized estimates of age<sub>c</sub> in the quadratic model and in models with additional elementary visual function predictors, i.e., near and far visual acuity measured with ETDRS charts measured at 4 m and 40 cm respectively, crowding intensity measured with LEA charts at 40 cm and contrast sensitivity represented by the Weber contrast threshold measured with a custom psychophysical task where subjects indicate which of the two figures (car or truck similar to UFOV stimuli) is currently presented. β’ = estimated standardized effect size, UFOV = Useful Field of View.</p
Scatterplots of elementary visual function test scores as a function of age.
<p>(A) Far and (B) near visual acuity measured with ETDRS charts at 4 m and 40 cm respectively. (C) Crowding intensity measured with LEA charts at 40 cm. (D) Weber contrast threshold measured with a custom psychophysical task where subjects indicate which of two figures (car or truck similar to UFOV stimuli) is currently presented. Black dots represent participants without any ophthalmic anomalies. Participants with subclinical ophthalmic findings are represented by colored symbols classified by the anatomical structures that were mildly affected. The lines represent the correlation between age and each tested function, none of them were statistically significant.</p
Retinal thickness measurements on spectral-domain optical coherence tomography (SD-OCT) in a patient with non-resolving central serous chorioretinopathy, who was treated with half-dose photodynamic therapy (PDT).
Overview of the SD-OCT at the visit prior to PDT (A). Measurements at last visit before PDT (B). Measurements at the first visit after PDT (C). Measurements at final visit (D).</p
Correlations of best-corrected visual acuity (BCVA) and parameters visible on optical coherence tomography (OCT) in non-resolving central serous chorioretinopathy (CSC) patients treated with half-dose photodynamic therapy (PDT).
