Anterior segment photograph at the first visit showing a totally detached retina in contact with the posterior surface of the lens. The peripheral retina could not be observed.

Because the detached retina was close to the lens, the peripheral retina could not be observed (fig. 1).
a B-mode echography of the right eye shows a high echo area in the vitreous cavity. b CT shows no evidence of calcification or tumor structure.

B-mode ultrasonography showed a diffuse, high echo area in the vitreous cavity with no apparent sign of calcification (fig. 2). The CT image that had been taken at a previous hospital 1 month earlier showed no evidence of calcification in the right eye (fig. 2).
MRIs taken at two different periods. T1 (a) and T2 (b) images taken 3 months before the first visit show a hyperintense lesion and a slightly hypointense lesion in the subretinal space, respectively. Both T1 (c) and T2 (d) images taken at the first visit show hyperintense lesions in the subretinal space. Tumor structure is not observed in the eye.

However, high-intensity signals were observed in the T2-weighted images in the same area on the second MRI, which was taken 3 months after the first MRI examination (fig. 3).
Fundus photograph of the right eye during the first operation under perfluoro-n-octane. Dilated retinal vessels, numerous microaneurysms, and intra- and subretinal exudates became visible.

Thus, the fundus, especially the peripheral area, could be seen better, and the clinical characteristics of Coats' disease, including dilated retinal vessels, numerous microaneurysms, and intra- and subretinal exudates became visible (fig. 4).
Fundus photograph of the right eye during the second operation under perfluoro-n-octane. The amount of exudates were reduced.
