“…However, the cupping of the disc is known to be increased in periventricular leukomalacia. Another study of 100 healthy children and adolescents revealed the median optic disc area to be 2.67 mm 2 , in subjects ages 3 to 19 years [30]. In another study the mean disc area was 2.49 mm 2 in healthy and glaucomatous eyes [31].…”

“…The age of the controls was greater compared with the patients with albinism. However, Hellstrom et al [30] found no change in the size of the disc, cup or rim with increasing age. In addition, we could not reliably use the ratio of disc diameter to distance of the optic nerve to the macula, used in other studies of optic nerve hypoplasia, due to the difficulty in defining the center of the foveal avascular zone in albinism.…”

Albinism, an inherited disorder resulting in reduced ocular melanin, is usually associated with reduced best-corrected visual acuity, nystagmus, foveal hypoplasia, and iris transillumination. However, a spectrum of findings has been reported, with foveal hypoplasia, nystagmus, and misrouting of the retinostriate fibers having been purported to cause reduced visual acuity. The purpose of this case-controlled study is to describe the optic nerve anatomy and peripapillary retinal vasculature in albinism and to determine if there are changes related to visual acuity. We evaluated digital fundus photographs using computer analysis software in 34 patients with albinism and 51 controls. Our data indicate that the optic disc diameter and optic nerve area are significantly smaller in patients with albinism than controls (p <0.001; p=0.0008, respectively). Significantly more patients with albinism also had a double ring sign, situs inversus, and a nasally-directed artery (p ≤ 0.0148). There were no significant differences between groups for optic nerve color, vessel branching pattern, cilioretinal artery, or number of vessels crossing the optic nerve margin. Correlation of best-corrected visual acuity to disc diameter and optic nerve area was poor (r=0.0542 r=0.1527, respectively). In this study, patients with albinism had mild optic nerve hypoplasia when compared to controls. Reduced best-corrected visual acuity is not explained by the optic nerve findings. Further studies are required to elucidate the causes of reduced best-corrected visual acuity in albinism.

Purpose The aim of this study was to assess visual perception at school age of children born preterm with known lesions to the posterior visual pathways or with ophthalmologic signs that might indicate such lesions. Methods The study group consisted of 91 patients born before the 37th gestational week. Visual perception was assessed using the TVPS-R (Test of Visual Perceptual SkillsRevised) and a structured interview. In addition, ophthalmologic and orthoptic examinations were performed. Results On the test of visual perception, 67% of the patients had results below the third percentile of the American reference group. This is to be compared with 10% of Swedish full-term controls. Scores below the third percentile were observed in 87% of the patients with known brain lesions, 48% of those with strabismus without known brain lesion, and 86% of those with reduced visual acuity in the absence of strabismus and known brain lesion. Conclusions Reduced visual perception is common among children born preterm who have strabismus and/or reduced visual acuity, as well as in those with known brain lesions. This study emphasises the need to find tools to identify and assess those patients who have visual perceptual problems that may restrict their ability to meet the demands of daily life.
