Abstract
To describe the usefulness of the magnetic resonance imaging-determined subretinal fluid volume to evaluate the therapeutic effect on the retinal detachment caused by uveitis with the clouded media. We obtained the images by half-Fourier single-shot rapid acquisition with relaxation enhancement magnetic resonance imaging using a microscopy coil. We measured the area of subretinal fluid on each image and calculated the volume of subretinal fluid by multiplying the total area by the slice thickness. A 56-year-old male who had lost his central visual field developed bullous retinal detachment in both eyes associated with uveitis. We treated him with steroid pulse therapy. We could not accurately evaluate the improvement of retinal detachment by ophthalmoscopy and ultrasonography as a result of the clouded media. We measured the volume of the subretinal fluid using magnetic resonance imagings. The volume of the subretinal fluid was observed to gradually decrease. These methods enable us to obtain clear magnetic resonance images within 2 seconds per slice. The reproducibility of the volumetry obtained by magnetic resonance imaging was excellent. The adaptation of half-Fourier single-shot relaxation enhancement imaging performed with a surface coil makes it possible to evaluate the volumetry of a targeted space while also being useful for evaluating the effect of the treatment.
