Burian's classification of exotropia based on the difference between the distance deviation and near deviation (distance/near differences) leaves some questions unanswered. Controversy exists concerning whether the divergence excess pattern is caused by an excess of divergence or by excessive accommodative...

Distance PD can be used to order any type of prescription glasses except reading glasses. Read below to learn how to calculate near PD for reading glasses. Dual PD DUAL PD, or monocular PD, consists of two numbers and is the distance between the centers of each pupil to the bridge of ...
Methods A retrospective study was conducted on a consecutive case series of 16 adult patients diagnosed with ARDE between 2008 and 2015. The clinical features evaluated included mean age and gender, primary position deviations at distance and near, measured in prism dioptres (pd), treatment offered...
Dual PD is usually written as 32/30. The first number refers to the right eye (OD), and the second number refers to the left eye (OS). How do you calculate near PD for reading glasses? Subtract 3 mm from your distance PD.
(AET) and its association with other clinical factors.The medical records of 176 children with refractive AET with a follow-up period鈮 1year were reviewed to identify a cohort of patients who achieved a stable alignment within 4 prism diopters (PD) of orthotropia at both distance and near ...
Differences between singular and dual PD SINGLE PD, which can be either a distance PD or a near PD, is thepupillary distance between the centers of two pupils. Most prescription eyewear, excluding reading glasses, can be ordered using PD. To figure out how to determine near PD for reading...
