Demographic features of idiopathic macular telangiectasia in Japanese patients.
Summary of "Demographic features of idiopathic macular telangiectasia in Japanese patients."
Idiopathic macular telangiectasia (MacTel) is classified into aneurysmal telangiectasia (type 1), perifoveal telangiectasia (type 2) and occlusive telangiectasia (type 3). Most instances of telangiectasia in Western countries are type 2. This study reports clinical and demographic features of MacTel in Japanese patients.
Newly diagnosed patients with MacTel were examined retrospectively. All patients underwent fluorescein angiography and optical coherence tomography.
Thirty-four eyes of 27 patients with MacTel were included. Twenty eyes of 20 patients (74.1%) had type 1, ten eyes of five patients (18.5%) had type 2, and four eyes of two patients (7.4%) had type 3. Foveal capillary dilatation and microaneurysms were observed in all except for one eye of early stage type 2 MacTel. Optical coherence tomography revealed cystoid macular edema in type 1, temporal foveal thinning and a loss of boundary between the inner and outer segments of photoreceptors in type 2, and thinning of all retinal layers around the fovea in type 3.
The most frequent among our patients was aneurysmal MacTel, whereas perifoveal MacTel was not common. Although the clinical characteristics were similar, the most common type was different from that in Western countries.

Medical and Biotech [MESH] Definitions
A species of FLAVIVIRUS, one of the Japanese encephalitis virus group (ENCEPHALITIS VIRUSES, JAPANESE), found in Australia and New Guinea. It causes a fulminating viremia resembling Japanese encephalitis (ENCEPHALITIS, JAPANESE).
A mosquito-borne encephalitis caused by the Japanese B encephalitis virus (ENCEPHALITIS VIRUS, JAPANESE) occurring throughout Eastern Asia and Australia. The majority of infections occur in children and are subclinical or have features limited to transient fever and gastrointestinal symptoms. Inflammation of the brain, spinal cord, and meninges may occur and lead to transient or permanent neurologic deficits (including a POLIOMYELITIS-like presentation); SEIZURES; COMA; and death. (From Adams et al., Principles of Neurology, 6th ed, p751; Lancet 1998 Apr 11;351(9109):1094-7)
A species of FLAVIVIRUS, one of the Japanese encephalitis virus group (ENCEPHALITIS VIRUSES, JAPANESE), which is the etiological agent of Japanese encephalitis found in Asia, southeast Asia, and the Indian subcontinent.
A group of interstitial lung diseases with no known etiology. There are several entities with varying patterns of inflammation and fibrosis. They are classified by their distinct clinical-radiological-pathological features and prognosis. They include IDIOPATHIC PULMONARY FIBROSIS; CRYPTOGENIC ORGANIZING PNEUMONIA; and others.
A form of MACULAR DEGENERATION also known as dry macular degeneration marked by occurrence of a well-defined progressive lesion or atrophy in the central part of the RETINA called the MACULA LUTEA. It is distinguishable from WET MACULAR DEGENERATION in that the latter involves neovascular exudates.
