AIM To identify the clinical features of optic nerve hypoplasia (ONH) and prevalence within a population of New Zealand children with severe visual impairment. METHODS Retrospective review of medical records of children with severe visual impairment registered with Blind and Low Vision Educational Network New Zealand. RESULTS Of 1500 children with(More)
Amblyopia is a neurodevelopmental disorder of the visual system that is associated with disrupted binocular vision during early childhood. There is evidence that the effects of amblyopia extend beyond the primary visual cortex to regions of the dorsal and ventral extra-striate visual cortex involved in visual integration. Here, we review the current(More)
BACKGROUND To evaluate the efficacy of wide-field digital retinal imaging for retinopathy of prematurity screening. DESIGN Retrospective study in a quaternary public neonatal intensive care unit. PARTICIPANTS A total of 108 premature infants screened for retinopathy of prematurity. METHODS Retrospective chart and photo review were performed on(More)
OBJECTIVES To investigate whether ocular torsion and vertical misalignment differ in the upright vs supine position in skew deviation and to compare these findings with those in trochlear nerve palsy. METHODS Ten patients with skew deviation, 14 patients with unilateral peripheral trochlear nerve palsy, and 12 healthy subjects were prospectively(More)
AIM To evaluate retinopathy of prematurity (ROP)-related visual impairment in New Zealand children. METHODS 22-year retrospective review of medical records of children with moderate to severe visual impairment registered with the Blind and Low Vision Education Network New Zealand. The cohort was divided into two periods (1991-2004; 2005-2012) for(More)
Trilateral retinoblastoma is characterized by retinal tumors in one or both eyes, as well as tumors of the pineal gland or parasellar region of the brain. Here we describe a 4-month-old girl, presenting with pituitary dysfunction, hypothalamic overgrowth syndrome and central blindness, in addition to suprasellar and bilateral retinal tumors. Biopsy of the(More)
PURPOSE To compare the accuracy of retinopathy of prematurity (ROP) screening between nurse specialists and an expert pediatric ophthalmologist. DESIGN A comparative case series of ROP screening in a level 2 neonatal intensive care unit setting where there is a higher threshold for accepting very premature or unwell neonates. METHODS Trained specialist(More)
PURPOSE To evaluate the accuracy of ultrasound biomicroscopy (UBM) for measuring the insertional distance from the limbus of horizontal extraocular muscles (EOM) that had previous surgery. METHODS This prospective, masked, observational study compared the distance of the horizontal EOM insertion from the limbus as measured by 50-MHz UBM, either(More)
Retinopathy of prematurity (ROP) is a multifactorial disease affecting the developing retinal vasculature and remains an important cause of blindness in very preterm infants. Rush disease, or aggressive posterior ROP (AP-ROP), progresses rapidly to stage 5 disease without exhibiting the classical course that includes stages 1-3. We describe an infant with(More)
