Effects of spectacles and telescopes on visual function in students with oculocutaneous albinism|
Jhetam, Siddeeqa & Mashige, Khathutshelo P
Purpose: To investigate the effects of spectacle and telescope corrections on visual acuity (VA), contrast sensitivity (CS) and
reading rates (RR) in students with oculocutaneous albinism (OCA).
Methods: An observational study design was conducted on 81 students with OCA. Distance and near VA, CS and RR were
measured without correction, with spectacle correction and with a combination of spectacle correction and telescopes.
Results: The mean distance and near VA values with a combination of spectacle correction and telescopes were significantly
better than those without correction and with spectacle correction alone (p = 0.01). Mean CS values achieved with spectacles
alone were significantly better than those obtained with a combination of spectacles and telescopes (p = 0.01). There was no
significant difference between logCS values obtained without correction compared to those obtained with a combination of
spectacle correction and telescopes. There were no significant differences between RR values obtained with a combination
of spectacles and telescopes and those without and with spectacle correction alone (all p > 0.05).
Conclusion: This article provides valuable information to eye care practitioners on the effects of spectacles and telescopes
on visual acuity, contrast sensitivity and reading rate in students with OCA.
