“…In both the ESC and FOA groups, mean aniso-astigmatism was negative, confirming the previously reported tendency toward greater astigmatism in the eye contralateral to the synostosis. 9,17 At the first examination, mean aniso-astigmatism was À0.5 for the ESC group and À0.38 for the FOA group. At the second examination, mean aniso-astigmatism was À0.28 for the ESC group and À0.41 for the FOA group.…”

“…Twenty-six percent had exodeviation, 14 % had an esodeviation and 5 % had a vertical deviation. Nine patients (10 %) had anisoastigmatism of 1D or more, which is lower than that reported in prior studies focusing solely on unilateral coronal synostosis [29,30]. Patients had pre-and post-operative ophthalmic exams, and the authors did not report any changes in the strabismus or refractive error following expansion cranioplasty.…”

“…In general, Levy et al found that astigmatism as well as anisoastigmatism developed to a greater degree on the side contralateral to the synostosis, which could be attributed to the abnormal development and shape of the orbit, where the superior orbital rim has been inferiorly displaced. Another group from the Children's Hospital Los Angeles followed 25 pediatric patients who had documented unicoronal craniosynostosis, of whom 14 (56 %) had amblyogenic anisometropia [30].As also seen in Levy's patients, the majority of these patients (79 %) with amblyogenic anisometropia had greater refractive error in the eye contralateral to the coronal synostosis [30]. In this same study, 72 % of affected Hispanic children had amblyogenic anisometropia compared to 14 % of effected non-Hispanic children, suggesting possible increased risk in certain populations [30].…”

“…As for management of refractive issues, specifically patients who suffer from unicoronal craniosynostosis, physician-investigators from both groups have studied the effect of the timing of fronto-orbital advancement [29,30]. Neither group found a significant relation between the timing of fronto-orbital advancement and whether amblyogenic anisometropia occurred.…”

Pediatric patients with craniofacial abnormalities face unique challenges requiring early intervention and longitudinal care for their ocular and systemic problems. Non-syndromic and syndromic craniosynostoses involve asymmetric development of the cranial vault and facial bones, which frequently leads to ophthalmic manifestations, including strabismus, refractive error, and visual field losses. In recent years, ophthalmologists, craniofacial surgeons, and pediatricians involved in caring for craniosynostosis patients have found that timely surgery and monitoring, using refined devices such as spectral-domain optical coherence tomography, can lead to improved quality of life and prognosis for these patients. We review relevant literature from the past 5 years describing and managing ocular symptoms of craniosynostosis.

“…In addition, there is a report of morning glory syndrome in the better‐seeing eye of a patient with combined anisometropic and strabismic amblyopia in the fellow eye . Finally, multiple cases have been reported of an association between unicoronal craniosynostosis and contralateral anisometropic amblyopia . Craniosynostosis most commonly occurs as part of Crouzon syndrome, which can be associated with strabismus and optic atrophy .…”

A case of amblyopia with contralateral optic nerve hypoplasia

We describe an unusual case of unilateral optic nerve hypoplasia (ONH) in a patient with contralateral anisometropic/strabismic amblyopia. A seven-year-old boy presented with visual acuities of 6/12 R and 6/18 L and eccentric fixation in the left eye. Cycloplegic retinoscopy was R +1.50/-0.50 ¥ 180 and L +5.25 DS. Funduscopy revealed optic nerve hypoplasia of the right eye. The patient fixated with his better-seeing right eye, despite the optic nerve hypoplasia. His reduced vision may be attributed to optic nerve hypoplasia in the right eye and amblyopia in the left. Although optic nerve hypoplasia can occur with ipsilateral amblyopia, we believe this is the first reported case of unilateral optic nerve hypoplasia in the fellow eye of an amblyopic patient. In a recent study in northwest England, the incidence of optic nerve hypoplasia was found to be 10.9 per 100,000 per year.2 Depending on the severity of the optic nerve hypoplasia, visual acuity (VA) can range from normal to no light perception. Visual fields can vary from full to severely restricted.Subtle cases of unilateral optic nerve hypoplasia with reduced VA are sometimes misdiagnosed as amblyopia.3 A diagnosis of amblyopia is particularly likely if the affected eye has an amblyogenic refractive error or constant unilateral strabismus. It is possible to have visual loss from unilateral optic nerve hypoplasia compounded by visual loss from one or more amblyogenic factors in the same eye. 1 We report an unusual case of previously undiagnosed unilateral optic nerve hypoplasia in a patient with contralateral anisometropic and strabismic amblyopia. CASE REPORTA seven-year-old Caucasian male child came for an eye examination with his mother, who reported a history of a left 'lazy eye' in the child. They were unaware of any abnormality of the right eye. At the age of five years, the patient had been prescribed glasses and patching of the right eye for eight hours per day for several months by another practitioner. According to his mother, the patching had improved his vision but she was hoping for further improvement. The child also had tried atropine drops but the treatment was reportedly unsuccessful. His current glasses were recently broken and unavailable. The child was a good student in the second grade, without medical problems. He took no medications. Birth and developmental history were unremarkable, with a birth weight of 3,580 g. He exhibited normal growth and stature.Pertinent examination findings are listed in Table 1 and the optic discs are shown in Figures 1A and 1B. Location of disc margins was determined by stereoscopic analysis of the nerves as well as the colour of tissue. Three experienced optometrists and an experienced technician determined the location of the disc margins independently from one another and all were in close agreement. The ratio of the distance between the centre of the optic nerve head and the centre of the macula to the mean optic nerve head diameter (DM:DD) indicated a small optic nerve head in the right eye. Mean disc ...
