剥離網膜の晩期自然復位

Spontaneous reattachment of the retina late after unsuccessful detachment surgery

　手術による復位に失敗した自験網膜剥離眼19例の経過観察の中から，最終手術後1年以上して，自然に網膜が復位した2症例を経験したので報告した．この復位は，残存硝子体の前方移動に伴う網膜牽引の解除によると思われたが，過去のこの種の自然復位（網膜下液の術後吸収遅延ではない）の報告をも調べ，たとえ復位が得られなくとも，網膜裂孔が閉じてさえすれば，長期的に観察していると，網膜が自然に復位する両可能性があることを述べた．もちろん，剥離が長期にわたれば，復位しても視機能の改善に多くを期待できないが．

Two cases of retinal detachment are described which underwent spontaneous reattachment more than one year after unsuccessful detachmentsurgery. One was a case with detachment due to macular hole and high myopia and the other to horseshoe tear in aphakia. After an initially succes-sful closure of retinal breaks, retinal detachment recurred due to postoperative proliferative vitreore-tinopathy. Spontaneous reattachment of the retina occurred 14 months after surgery in both cases. The reattachment was apparently due to anterior displacement of the vitreous with release of vitreo-retinal traction.

These cases illustrate that later spontaneous reattachment of the retina is a possibility after an initial surgical failure provided that the retinal breaks have been closed.
