Types of Refractive Errors and Visual Outcome with Spectacles and Telescopes among Albino patients.
Al-Shifa J Ophthalmol Jan ;17(1):13-7.

Purpose: To determine types of refractive error and Visual Outcome with spectacles and telescopes in Albinism Methodology: This was a Cross Sectional study conducted in Low Vision Department of Shifa Eye Foundation Hospital Haripur. Study duration was 6 months from March 2020 to September 2020. Sampling technique was non-probability convenience sampling. Refractive errors were evaluated subjectively and objectively. Best corrected visual acuity with spectacles and telescopes were assessed binocularly. Results: A total of 37 patients with Albinism were examined and divided into two groups i.e., Ocular Albinism (OA) and Oculocutaneous Albinism (OCA). The frequency of OCA was 29 and that of OA was 07. OCA Astigmatism was the most common refractive error about 72.41%. Astigmatism was found with a mean value of 2.71D. Myopia had a mean value of -6.7D, while the degree of Hyperopia was found with a mean value of 7.20D. Main Refractive Errors found among OA was Myopia and Astigmatism with equal percentage of 42.85%, Hyperopia was 14.28%. Myopia was found with a mean value of - 9.66D. Astigmatism was found with a mean value of 3.5D and Hyperopia was 5.12D. in OCA the uncorrected Visual Acuity (VA) was found with a mean value of 0.99 Log MAR. in OA it was found with a mean value of 0.90 Log MAR. With Spectacle in OCA it was 0.82 Log MAR while with Galilean telescope the value was 0.54 Log MAR. With Keplerian telescope it was 0.25 Log MAR and in OA with Spectacles the mean value was 0.72 Log MAR. Conclusion: Astigmatism was the most significant refractive error among Albino patients. VA had improved with spectacles and telescopes. Keplerian telescope improved vision more significantly compared with Spectacles and Galilean telescope.
