Figure 1. Summary of best corrected visaul
acuity (BCVA) data obtained in oculocutaneous albinism (OCA) and ocular
albinism (OA) patients.
A: Open symbols denote patients with
identified sequence changes on both alleles; closed symbols denote
patients with identified sequence changes on a single allele only.
B:
Patients
without
identified
variants. Visual acuity is given as the
negative logarithm of the minimum angle of resolution (logMAR) and was
obtained with Teller acuity cards (6 months-3 years), Cardiff Crowding
cards (up to 3 year of age), Lea cards (2–6 years), and number charts
(6 years and older). Single patients are presented with follow-up data.
Nonquantifiable data were transferred into digital data according to
Schulze-Bonsel and Bach (hand movement: logMAR 2.5, counting fingers:
logMAR 2 [
42]).
