We report the case of a patient with cystic fibrosis who suffered severe bilateral uveitis, with hypopyon, retinal vasculitis, and polyarthritis when he was 6 years old. No etiology could be found. Multiple sclerosis began when he was 22 years old. This panuveitis was clinically very different from the uveitis usually associated with multiple sclerosis. Polyarthritis and skin vasculitis have been reported in the course of cystic fibrosis, but no uveitis nor retinal vasculitis have been described. This raises the question of the role of multiple sclerosis and cystic fibrosis in the pathogenesis of this case of uveitis.
Stage IV hypertensive retinopathies in children have been described, but their incidence appears to be rare. Most etiologies are nephropathies. The authors present a clinical case of malignant high blood pressure in a young girl whose ophthalmological tests detected an unusual nephropathy, the Ask-Upmark kidney, illustrating the importance of determining high blood pressure chronicity and using Kirkendall's classification. Systematic fluorescein angiography and NMR on atypical subjects prevents the diagnosis of Leber neuroretinis, the main differential diagnosis. Early treatment of high blood pressure can avoid complications such as macular exudes.
The authors report a case of amaurosis fugax treated first by systemic fibrinolysis and then by antiplatelet treatment. A 47-year-old suffering from transient amaurosis due to recurrent occlusion of retinal arterial branches improved after treatment and showed no recurrence. This protocol appears effective in cases of probable embolus in a young patient with no contraindications and when flow is not reestablished (amaurosis fugax), or when the required 6-hour time delay is respected.
