“…Pupil examination, extra‐ocular motility and cover testing at near and distance (with and without spectacles) and colour vision may assist with identifying optic nerve pathology and/or intracranial pathology. Childhood brain tumours (for example craniopharyngioma) will have ocular symptoms or unexplained poor vision in 30 per cent of cases at presentation and should be considered in the differential diagnosis of the child with reduced vision with no other clear cause …”

Amblyopia is a common cause of reduced vision in children. The clinical diagnosis is complicated and requires consideration of the severity of vision loss relative to the characteristics of the disrupting amblyogenic factor. Added to the challenge of a thorough examination of very young children, is the weight of consequence if the amblyogenic factor is not identified and treated appropriately within clinically recommended time frames. Further, the poor visual function may be a symptom of more sinister underlying pathology impacting the visual pathway. This review presents an evidence-based, pragmatic approach to the diagnosis of amblyopia, as a means for guiding best practice for the care of children who present with reduced vision.

“…Long‐lasting, dense RHs may cause visual impairments like amblyopia, myopia and haemorrhage‐related retinal toxicity . RH in term newborns is generally also associated with more severe situations, such as intracranial haemorrhage, craniocerebral injury and shaken baby syndrome . In the study we focused on haemorrhages of full‐term newborns, without consideration of pre‐retinal and vitreous haemorrhages that are often seen concurrently in patients with non‐accidental injury and other bleeding diatheses.…”

Background To define a new quantitative grading criterion for retinal haemorrhages in term newborns based on the segmentation results of a deep convolutional neural network. Methods We constructed a dataset of 1543 retina images acquired from 847 term newborns, and developed a deep convolutional neural network to segment retinal haemorrhages, blood vessels and optic discs and locate the macular region. Based on the ratio of areas of retinal haemorrhage to optic disc, and the location of retinal haemorrhages relative to the macular region, we defined a new criterion to grade the degree of retinal haemorrhages in term newborns. Results The F1 scores of the proposed network for segmenting retinal haemorrhages, blood vessels and optic discs were 0.84, 0.73 and 0.94, respectively. Compared with two commonly used retinal haemorrhage grading criteria, this new method is more accurate, objective and quantitative, with the relative location of the retinal haemorrhages to the macula as an important factor. Conclusions Based on a deep convolutional neural network, we can segment retinal haemorrhages, blood vessels and optic disc with high accuracy. The proposed grading criterion considers not only the area of the haemorrhages but also the locations relative to the macular region. It provides a more objective and comprehensive evaluation criterion. The developed deep convolutional neural network offers an end‐to‐end solution that can assist doctors to grade retinal haemorrhages in term newborns.
