Anterior chamber depth and axial length affect clinical performance of Spot Vision Screener

ABSTRACT Purpose: The aim of this study was to evaluate the effect of anterior chamber depth and axial length on clinical performance of the Spot Vision Screener in detecting amblyopia risk factors in children aged 3-10 years. Methods: A total of 300 eyes from 150 patients aged 3-10 years were prospectively tested with Spot Vision Screener (firmware version 3.0.02.32, software version 3.0.04.06) and a standard autorefractometer (Nidek ARK-1). The anterior chamber depth and axial length were measured with an optical biometer (Nidek AL-Scan). The sensitivity and specificity values for detecting significant refractive errors using the referral criteria of the American Association for Pediatric Ophthalmology and Strabismus were determined. Pearson ’ s correlation analysis was employed to evaluate the relationship between the Spot Vision results and the anterior chamber depth and axial length. Results: Compared with the standard autorefractometer results, the Spot Vision Screener ’ s sensitivity and specificity was 59% and 94%, respectively. The differences between the cycloplegic autorefractometer and the Spot Vision Screener spherical equivalents were negatively correlated with anterior chamber depth (r=-0.48; p

Conclusions: Glial heterotopia in the orbit is a rare clinical entity most commonly presenting in children. We present 2 cases of orbital glial heterotopia in adults, with a literature on these lesions in both the pediatric and adult populations. Surgeons and pathologists should be aware of this atypical presentation in adulthood. Biopsy is required for diagnosis but is not without risk. Prognosis is generally favorable. Orbital glial heterotopia, commonly considered a rare congenital lesion generally presenting in children, may first become symptomatic in adulthood. Biopsy is required for diagnosis, with symptoms and p...

We describe the case of a 15-month-old girl presenting with strabismus and proptosis who had a retrobulbar intraconal cystic lesion displacing the optic nerve, with an adjacent middle cranial fossa anomaly. Aspiration of the orbital cyst tested positive for asialotransferrin, raising the suspicion of a direct communication with cerebrospinal fluid (CSF). Subsequent fine cut CT scanning disproved any connection with the intracranial space, and the cyst was excised complete and intact. Histopathology showed a conjunctival epithelial cyst. To our knowledge, this is the first case report in the literature of an asialotransferr...

Conclusions Despite being a rare condition, Gradenigo syndrome should be taken into account as potential differential diagnosis in children referred to emergency department for recurrent headache and strabismus. An accurate anamnesis to document recent ear infection is mandatory to orientate the diagnosis and focus radiological investigations. Early recognition and timely intervention may allow conservative management to succeed, avoiding the need for surgery and serious sequelae.

CONCLUSION: Granulomatosis with polyangiitis is a rare yet potentially blinding cause of inflammatory optic neuropathy. Optic neuropathy in granulomatosis with polyangiitis may occur in the absence of systemic symptoms of disease activity and is challenging to distinguish from other inflammatory and non-inflammatory disorders affecting visual acuity. Several clinical and imaging clues suggest that optic neuropathy results from the development of an extravascular granulomatous process within the optic nerve sheath in the orbital apex, a place that is difficult to image. In a granulomatosis with polyangiitis patient with une...

Purpose: Preterm children have an increased risk of impaired vision from retinopathy, strabismus, and high refractive error. The aim of this study was to investigate the relationship between foveal parameters generated by optical coherence tomography angiography and visual function in preterm children. Methods: Eighty eyes (32 eyes of former preterm infants and 48 age-matched full-term control eyes) were analyzed. Subjects underwent complete eye examinations including best-corrected visual acuity and retinal imaging with the Optovue XR Avanti optical coherence tomography angiography device. Foveal morphologic paramete...

CONCLUSION: Coats plus syndrome is an extraordinarily rare autosomal recessive disease, caused by mutations in the CTC1 gene, which involves the appearance of retinal telangiectasias, brain cysts, calcifications in deep nuclei and leukoencephalopathy, as well as other bone and gastrointestinal conditions. Treatment is symptomatic and the disease has a poor prognosis. PMID: 31559627 [PubMed - in process]
