Main Uses: Detection of phoria and tropia Helps identify latent squint (phoria) and manifest squint (tropia). Measurement of horizontal deviation Used for esophoria / esotropia and exophoria / exotropia. Measurement of vertical deviation Helps detect hyperphoria or hypophoria. Breaks binocular fusion Convert
