Restitution of potential visual acuity in low vision patients with the use of yoke prisms
2021, Journal of OptometryCitation Excerpt :One of the most common tools used today in ophthalmology is the potential acuity meter (PAM) which provides estimates of PVA at the macula in the presence of pathology obstructing macular access to incoming light stimuli. The PAM estimates provide a measure of PVA after interventions to remove pathology like cataracts.16 The need to know PVA in cases with LV secondary to maculopathies is similar like in cases without maculopathies in order to plan and assess LVR interventions.
Clinician versus potential acuity test predictions of visual outcome after cataract surgery
2009, OptometryCitation Excerpt :Distance VA was measured at 3.2 m under monocular conditions using an early treatment diabetic retinopathy study (ETDRS) logMAR chart (mean luminance 200 cd/m2), using a by-letter scoring system (0.02 log units per letter) and a termination rule of no letters called correctly on a line.22 The standard Potential Acuity Meter (Mentor Inc., Norwell, Massachusetts) procedure5 was used, and Snellen VA was determined as the smallest line at which the majority of letters were correctly identified. The Rodenstock Retinometer (Rodenstock, London, United Kingdom) was the interferometer used following the standard procedure23 with the gratings presented at 4 random orientations: horizontal, vertical, or oblique (45° to the right or the left).
Capabilities of potential vision test measurements. Clinical evaluation in the presence of cataract or macular disease
2006, Journal of Cataract and Refractive SurgeryCitation Excerpt :Distance VA was measured at 3.2 m under monocular conditions using a Bailey-Lovie logMAR chart (mean luminance 200 cd/m2) using a by-letter scoring system (0.02 log units per letter) and a termination rule of no letters called correctly on a line.40 The standard PAM (Mentor) procedure was used,6,41 and VA was determined as the smallest line at which the majority of letters were correctly identified. The LI (Rodenstock) was measured using the Rodenstock retinometer following the standard procedure,20,25,42 with the gratings presented at 4 random orientations: horizontal, vertical, or oblique (45 degrees to the right), and oblique (45 degrees to the left).

2005, Journal of Cataract and Refractive SurgeryCitation Excerpt :The patient was asked to read the letters through a standard pinhole (1.5 mm aperture, Precision Vision). The PAM test (PAM-1000, Mentor) was then given as previously described.1 The patients had phacoemulsification with foldable intraocular lens implantation under topical anesthesia with monitored anesthesia care.
