網膜色素線条に併発した黄斑部脈絡膜新生血管への手術治療

Surgical removal of submacular choroidal neovascularization associated with angioid streaks

　網膜色素線条患者4例5眼を対象として，黄斑部脈絡膜新生血管を手術的に除去し，未治療の自然経過群7例8眼と，視力予後，最終的な瘢痕組織の大きさについて比較検討した。最終観察時までの視力変化の平均は，未治療群で−0.9（log MAR），手術群で＋0.1であった。最終視力0.1以上を得たものは，手術群で4眼（80％），未治療群で3眼（38％）のみであった。また，手術群では未治療群に比して瘢痕形成が小範囲にとどまった。治療群5眼の経過をここに報告する。

We reviewed 5 eyes of 4 patients who underwent surgical removal of submacular choroidal neovasculariza-tion (CNV) as complication of angioid streaks. Their ages ranged from 55 to 70 years, average 61 years. After 14 to 28 months, average 19 months, after surgery, visual acuity improved in 4 eyes and remained unchanged in one eye. Final visual acuity of 20/200 or better was attained in 4 eyes. Another series of 8 eyes of 7 patients with CNV and angioid streaks which received no surgery were also evaluated. Only 3 of the 8 eyes (38%) had final visual acuity of 20/200 or better. Final submacular scar was smaller in eyes treated by surgery. The findings show the usefulness of surgical removal of CNV eyes with angioid streaks.
