Twenty-three children (16 girls, 7 boys, aged 6-17 years) who presented with the specific complaint of blurred vision were diagnosed as having functional visual loss. Symptoms were intermittent in seven children. Associated signs and symptoms were common and included headaches, visual field loss, diplopia, micropsia, voluntary nystagmus, and spasm of the near reflex. Our treatment consisted of reassurance and follow-up. Resolution of symptoms occurred within 24 hours in one third and within two months in three-quarters of our patients. Parental support and encouragement were associated with more rapid resolution. Recurrence of symptoms and late onset of somatic complaints were rare. Conflicts related to family or school environment were common. Four children had been sexually or physically abused. Our experience suggests that, regardless of the duration or severity of symptoms, functional visual loss in children can usually be treated with reassurance. We believe that psychiatric referral is not necessary for most patients. Sexual or physical abuse should be considered as a possible predisposing factor.

Central serous chorioretinopathy (CSC) is a disease of the retina characterized by serous detachment of the neurosensory retina secondary to one or more focal lesions of the retinal pigment epithelium (RPE). CSC occurs most frequently in mid-life and more often in men than in women. Major symptoms are blurred vision, usually in one eye only and perceived typically by the patient as a dark spot in the centre of the visual field with associated micropsia and metamorphopsia. Normal vision often recurs spontaneously within a few months. The condition can be precipitated by psychosocial stress and hypercortisolism. Ophthalmoscopic signs of CSC range from mono- or paucifocal RPE lesions with prominent elevation of the neurosensory retina by clear fluid - typical of cases of recent onset - to shallow detachments overlying large patches of irregularly depigmented RPE. The spectrum of lesions includes RPE detachments. Granular or fibrinous material may accumulate in the subretinal cavity. Serous detachment often resolves spontaneously. From first contact, counselling about the potential relation to stress and glucocorticoid medication is warranted. After 3 months without resolution of acute CSC or in chronic CSC, treatment should be considered. Resolution of detachment can usually be achieved in acute CSC by focal photocoagulation of leaking RPE lesions or, in chronic CSC, by photodynamic therapy. The effect of therapy on long-term visual outcome is insufficiently documented. Reattachment within 4 months of onset is considered a relevant therapeutic target because prolonged detachment is associated with photoreceptor atrophy. This suggests that the value of treatment depends upon proper selection of cases that will not resolve without therapy. Chronic CSC may be difficult to differentiate from occult choroidal neovascularization secondary to CSC. Patients with chronic CSC who receive glucocorticoid treatment for systemic disease can often be managed without having to discontinue this medication.

Central serous chorioretinopathy is a common disease of the retina, often mistaken for degeneration of the macula or uveitis. The disease is related to stress and treatment is with glucocorticoids, but it is also seen in connection with pregnancy. The disease can lead to permanent visual loss. Patients with blurred vision, metamorphopsia and micropsia should be examined by an ophthalmologist within 24 hours because the condition may involve treatment-eligible subretinal neovascularization.
