A single case of multifocal choroiditis with panuveitis (MFCPU) was investigated by a three-dimensional (3-D) high-penetration optical coherence tomography. The HP-OCT is based on a swept-source OCT technology, uses a probe beam with a center wavelength of 1060 nm, and possesses a depth resolution of 10.4 micromin tissue. Two eyes of an MFCPU patient were involved in this study. The eyes were also examined by color fundus photograph, fluorescein angiography (FA), and indocyanine green angiography (ICGA). Findings in these four modalities are comparatively discussed. The OCT scans revealed the following characteristic properties of the lesion sites. Thinning of the retina, destructuring of the retinal layers, and disappearance of the junction of the inner and outer segments of the photoreceptor (IS/OS). Due to the high penetration of this OCT system, the following characteristic properties of the lesions were also observed: localized thinning of the choroid, occlusion of the choroidal vessels, and localized hyper-reflectivity that may represent hyper-pigmentation of the choroid.

Vogt-Koyanagi-Harada (VKH) disease is defined as a severe bilateral, chronic granulomatous panuveitis associated with serous retinal detachments, disk edema, and vitritis, with central nervous system, auditory, and integumentary manifestations. It is an autoimmune inflammatory condition mediated by T cells that target melanocytes in individuals genetically susceptible to the disease. Vogt-Koyanagi-Harada disease presents clinically in 4 different phases: prodromal, acute inflammatory, chronic, and recurrent, with extraocular manifestations including headache, meningitis, hearing loss, poliosis, and vitiligo. Optical coherence tomography (OCT) allows earlier diagnosis of VKH disease by revealing heterogeneous exudative detachments of the retina in the acute stage and choroidal thickening, and by demonstrating choroidal thinning in the chronic stage. Treatment of this disease is initially with intravenous corticosteroids, with, if needed, a transition to immunosuppressant drugs for long-term control. Patients with VKH disease can have good final visual outcomes if treated promptly and aggressively.
