Facioscapulohumeral (FSH) muscular dystrophy is known to be associated with retinal telangiectasis. However, there are only few reports of severe visual loss due to exudative complications, so the risk to vision has not been established. Because of the possible therapeutic implications, we have described two cases of young girls who developed FSH muscular dystrophy and exudative retinal detachment due to telangiectasis. In the first patient, the severity of the disease precluded visual recovery despite extensive photo- and cryotherapy. In the other, visual acuity in both affected eyes was retained after treatment. Fundus examinations in young children at risk of having the gene for FSH muscular dystrophy may be justified so that retinal vascular disease can be detected before it becomes untreatable.

Because of occasional reports of exudative retinal detachment with facioscapulohumeral muscular dystrophy (FSH) and deafness, we sought to determine by fluorescein angiography whether there is any general relationship between FSH muscular dystrophy and retinal vascular disease. Peripheral retinal capillary abnormalities, comprising telangiectasis, closure, leakage and microaneurysm formation, were demonstrated by angiography in 56 out of 75 individuals with clinical or genetic evidence of FSH. Only 3 patients had relevant ophthalmoscopic abnormalities of the posterior pole and in only 1 was there consequent visual loss. This study included one FSH family in which the propositus was treated for exudative retinopathy and 13 other subjects had telangiectasis, and 8 cases (including 3 parents of apparently 'sporadic' FSH cases) in which fluorescein angiography confirmed the abnormal genotype, even though clinical examination of skeletal muscle revealed no clear abnormality. There was no correlation between the severity of the muscle disease and the extent of the retinal vascular abnormality. Visual complications of telangiectasis, although rare, may present early in life and before there is overt evidence of muscle disease. Since visual loss may be preventable, ophthalmic examination should be undertaken on infants at risk of having the abnormal gene. The findings support the hypothesis that retinal capillary abnormalities are an integral part of the FSH muscular dystrophy syndrome and raise the question as to whether analogous capillary abnormalities could be implicated in the pathogenesis of FSH muscle disease.

A 22-year-old patient with newly diagnosed facioscapulohumeral (FSH) muscular dystrophy had a macular lesion in her right eye and poor central vision, which had been present since early childhood. Fluorescein angiographic examination revealed bilateral peripheral vessel closure, peripheral retinal telangiectasis, and hyperfluorescence in both foveae. This widespread vascular abnormality was deemed responsible for her macular disease. Her mother, brother, and sister, all of whom are affected by varying degrees of FSH muscular dystrophy and clinical deafness, also have abnormal retinal vasculature, as determined by fluorescein angiography. However, none had related visual symptoms and two showed no ophthalmoscopic evidence of vascular abnormalities. In young patients with unexplained retinal vascular lesions, the diagnosis of FSH muscular dystrophy should be considered. Similarly, young patients with FSH muscular dystrophy should be examined for sight-threatening and potentially treatable vascular retinopathy.
