シリコーンオイル併用硝子体手術を施行した朝顔症候群に伴う網膜剝離の1例

Retinal detachment in a case of morning glory syndrome treated by vitreous surgery with silicone oil tamponade

要約　目的：朝顔症候群に伴う網膜剝離に対して硝子体手術を行った症例の報告。症例：42歳の男性が右眼の視力低下を主訴に受診した。所見：視神経乳頭は朝顔様で，網膜は全剝離の状態であり，硝子体手術，シリコーンオイル置換を施行した。術後シリコーンオイルが網膜内に迷入したため，脳脊髄腔への移行を憂慮し，シリコーンオイルを抜去した。剝離が再発したためシリコーンオイル置換術を再施行し，乳頭周囲レーザー光凝固を追加し，網膜復位を得た。結論：朝顔症候群に伴う網膜剝離は視神経陥凹部と網膜下への交通が推測され，本症例では視神経乳頭周囲へのレーザー光凝固とシリコーンオイル置換が有用であった。

Abstract.　Purpose：To report a case of morning glory syndrome who received surgery for retinal detachment. Case：A 41-year-old male presented with impaired visual acuity in the right eye since 2 months before. His right eye had had poor vision since childhood. Findings：Corrected visual acuity was 0.01 right and 1.0 left. The right eye showed total detachment with funnel-formation anterior to the disc. He was treated by vitreous surgery with silicone oil tamponade. The retina was redetached after silicone oil was removed 10 days after surgery. The retina became reattached after silicone oil tamponade with photogoatulation around the disc. Conclusion：There is a possibility that retinal detachment was due to presence of communication between the subretinal space and pit of the optic disc.
