“…20 Optic disc pathology can be associated with strabismus in children. 21 -24 In this study, 17.8% of strabismus patients presented with abnormal fundus findings, and optic nerve hypoplasia was the most common finding. Optic nerve hypoplasia is known to be the most common congenital abnormality of the optic nerve, and it is defined as a reduced number of axons in the optic nerve and a small optic disc.…”

Purpose: Magnetic resonance imaging (MRI) of the brain can provide valuable information about structural abnormalities in strabismus. The aim of this study was to evaluate the utility of MRI in this regard and to identify risk factors for abnormal MRI results in children with strabismus. Methods: A retrospective analysis of children <18 years of age presenting with strabismus, who underwent brain MRI at Pusan National University Hospital (Busan, Korea) between January 2012 and March 2017, was performed. Clinical characteristics, MRI results, and ophthalmologic findings were reviewed. Findings were classified as normal or abnormal according to MRI results. Additionally, patients were divided according to age to compare characteristics of infantile and childhood strabismus. Results: A total of 90 patients (47 [52.2%] male, 43 [47.8%] female; mean age, 2.19 ± 0.53 years) were enrolled. Of those, 64 (71.1%) presented with normal and 26 (28.9%) with abnormal MRI results. The age at presentation was lower and abnormal findings on fundus examination were more common in the abnormal MRI group ( P = .002 and P = .008, respectively). Among the patients, 46 (51.1%) had infantile strabismus and 44 (48.9%) had childhood strabismus. Global developmental delays, speech delays, and MRI abnormalities were more common in patients with infantile than in those with childhood strabismus. Ptosis and headaches were more common in patients with childhood strabismus ( P = .025, P = .025, respectively). Conclusion: Brain MRI was helpful for accurate diagnosis and treatment of strabismus in younger children, those with abnormal findings on fundus examination, and infants with developmental, especially speech, delays.

“…По степени снижения зрительных функций атрофия зрительного нерва подразделяется на полную и частичную (ЧАЗН), а по времени возникновения -на врожденную и приобретенную. Причиной врожденной ЧАЗН часто является перинатальная патология: внутриутробная инфекция, ишемически-гипоксическая энцефалопатия, гидроцефально-гипертензионный синдром, внутричерепные кровоизлияния при тяжелом родоразрешении, кровоизлияния в оболочки зрительного нерва и сетчатку, хроническая гипоксия и вторичные нарушения микроциркуляции тканей глаза и мозговых структур [1][2][3][4][5].…”

Background. Congenital partial atrophy of the optic nerve is one of the main causes of blindness and low vision in patients with fundus pathology, and the study of color vision is important in diagnosis and monitoring visual functions in patients with this disease.Purpose: to study the possibilities of using the own developed method of quantitative and qualitative assessment of color vision in patients with partial optic nerve atrophy.Materials and methods. 55 patients aged from 8 to 20 years with congenital partial atrophy of the optic nerve (PAON) with a typical fundus pattern and EFI indicators for this disease were observed. The control group included 116 people of the same age without fundus pathology and with normal visual acuity. To study color vision in both groups, the classic FarnsworthMunsell Dichotomous D15 Test and the own developed method for quantitative and qualitative assessment of color vision were used.Results. The method developed by us made it possible to identify color perception disorders of varying severity in the majority (about 90 %) of patients with PAON. In the control group, no color perception disorders were detected in more than 70 % of the subjects. Quantitative assessment of color vision conducted using the method developed by us demonstrates significantly higher indicators of the total error of perception of color tones in patients with PAON (35.6 ± 3.2 degrees for a better-seeing eye and 39.9 ± 3.3 degrees for a worse-seeing eye) in comparison with the subjects of the control group (6.2 ± 1.1 degrees for a better-seeing eye and 7.5 ± 1.3 degrees for a worse-seeing eye). The severity of color perception disorders in patients with PAON does not depend on age, but has a significant inverse relationship with visual acuity. In the group of patients with PAON, when examining both better-seeing eye and worse-seeing eye, perception disorders of all color tones are detected with a slight predominance of disorders of perception of red, green and blue. The method developed by us has sufficiently higher sensitivity and specificity in comparison with the classic Farnsworth-Mansell D-15 test.Conclusion. The method developed by us makes it possible to effectively carry out a quantitative and qualitative assessment of the state of color perception in patients with PAON.
