加齢黄斑変性で自然寛解したプラーク病変

Spontaneous resolution of plaque in age-related macular degeneration

（P−2-101）　加齢黄斑変性が右眼にある71歳男性を約8年間追跡した。初診から4年後に，インドシアニングリーン蛍光造影の後期像での過蛍光斑plaqueが出現した。その境界は不明瞭で，1乳頭径大であった。このplaqueは以後，緩慢に縮小し，眼底の滲出性変化も消失した。境界が不鮮明なpoorly definedpiaqueは新生血管そのものではなく，新生血管発生の場にすぎない所見である可能性がある。

We followed up, for about 8 years, a 71-year-old male with age-related macular degeneration in his right eye. A plaque was first detected 4 years after start of observation. It appeared as an poorly-defined hyperfluorescent spot during the late phase of indocyanine green angiography. Its size was one disc diameter. The plaque underwent spontaneous resolution associated with disappearance of exudative lesions. The finding seemed to show that poorly-defined plaque may not correspond to neovascularization itself but may reflect a potential site where choroidal neovascularization may grow.
