Morphision test. (a) Plate 1 includes a modified Amsler chart

Product Description

Download scientific diagram | Morphision test. (a) Plate 1 includes a modified Amsler chart consisting of a grid of white lines on a black background with external dimensions of 10 by 10 cm and comprising 16 individual grid squares measuring 2.5 by 2.5 cm. At the center is the fixation point where observers were required to fixate during the presentation of the chart. This plate was used to detect metamorphopsia and localize the area of distortion. (b) Plate 2 includes 4 (A-D) modified Sine Amsler Charts where the straight lines have been replaced by sine curves of different frequencies [half a cycle (A), 1 cycle (B), 2.5 cycles (C), and 4 cycles (D) per 5 cm line], a chart representing a cushion- (E) and a barrel-like (F) distortion. Plates 3-50 consist of 6 groups (series A-F) with 8 charts. (c) shows example of Series C. The plates in individual groups have fixed frequency and increasing amplitudes of distortion in 0.05 degree-steps (from 0.05 to 0.4 degrees) (1-8 plates) from publication: Morphision: A method for subjective evaluation of metamorphopsia in patients with unilateral macular pathology (i.e., full thickness macular hole and epiretinal membrane) | Background: Lack of clinical tests to quantify spatial components of distortion in patients with full thickness macular holes (FTMH) and epiretinal membranes (ERM). Aim: To develop a test for subjective evaluation of visual distortion in the central visual field around | Epiretinal Membrane, Vision Disorders and Patients | ResearchGate, the professional network for scientists.
