    ABSTRACT: The authors report a case of acute posterior multifocal placoid pigment epitheliopathy evaluated by autofluorescence, fluorescein angiography, indocyanine green angiography, high-definition optical coherence tomography, and microperimetry in both the acute and the post-acute phase. Based on the integrated findings, the authors believe that acute posterior multifocal placoid pigment epitheliopathy is an inflammatory disease that primarily affects the choroid and that the retinal pigment epithelium is secondarily involved in the course of the disease.

    ABSTRACT: We report a case of acute posterior multifocal placoid pigment epitheliopathy (APMPPE), which was difficult to differentiate from posterior pole-type Vogt-Koyanagi-Harada (VKH) disease because the lesions were mainly located in the macula bilaterally. A 33-year-old man presented with rapid bilateral loss of vision. Fundoscopy revealed yellow-white subretinal lesions in the posterior pole of both eyes. Optical coherence tomography (OCT) revealed the presence of subretinal fluid with a subretinal septum. After initiation of systemic steroids, OCT revealed that the amount of subretinal fluid decreased immediately. However, vision loss was less responsive to the therapy, and OCT revealed partial reorganization of the inner segment/outer segment (IS/OS) line in the bilateral macular areas after therapy. In our case, the location of the macular lesions made it difficult to differentiate APMPPE from VKH disease by fluorescein angiography. OCT images showed VKH disease-like findings of serous retinal detachment with a subretinal septum. The outer nuclear layer disappeared and the IS/OS line in the affected area was disorganized in the acute stage of the disease. In this case, the rapid loss of vision was specific to the onset pattern of APMPPE, and the slow response to therapy was very different from the response typically observed in VKH disease. Thus, careful consideration of the clinical course is important for diagnosing APMPPE.

    ABSTRACT: Optical coherence tomography (OCT) is a non-contact noninvasive technique that allows in vivo imaging of the retina, choroid, optic nerve head, retinal nerve fiber layer, and the anterior structures of the eye. It was introduced into clinical practice two decades ago. Advances in OCT technology have been achieved by searching ultra-high-resolution OCT, adaptive optics OCT, eye-tracking OCT, and changes in signal detection technique from time-domain (TD) to spectral-domain (SD) detection. Today, SD OCT has become a part of routine uveitis practice. Apart from its diagnostic value in uveitis, OCT has enabled objective assessment of treatment response and provided predictive value for visual recovery and prognosis of uveitic entities. It is the standard diagnostic technique in the detection, monitoring of treatment, and determination of prognosis in uveitic macular edema as well as other inflammatory macular pathologies, including epiretinal membrane formation, vitreomacular traction, foveal atrophy, and lamellar/full-thickness macular holes. OCT has also shed light on the pathophysiology of several posterior uveitic entities. SD OCT has enabled visualization of four lines in the sensory retina which represent the external limiting membrane, the photoreceptor inner and outer segment junction, the photoreceptor outer segment and the retina pigment epithelium junction, and the retina pigment epithelium-choriocapillaris complex. Thus, we have gained substantial information about the pathologic and structural changes in uveitic conditions with primary or secondary outer retinal involvement. SD OCT has also provided invaluable information on the inner retinal and the vitreoretinal interface changes in uveitic conditions. With the introduction of enhanced depth imaging, visualization of the choroid and choriocapillaries has become possible. Therefore, OCT has become an indispensible ancillary test in the diagnosis and management of inflammatory diseases involving the retina and/or the choroid. As OCT technology continues to develop further it will provide new insights into the retinal and choroidal structure and the pathogenesis of posterior uveitic entities.
