眼球打撲の既往がなく前房出血・眼痛を併発した網膜剝離の1例

Hyphema and ocular pain in a case of nontraumatic retinal detachment

要約　65歳女性が3日前に突発した右眼の眼痛と視力低下で受診した。左眼に-15Dの近視があり，矯正視力は右手動弁，左0.8であった。眼圧は右6mmHg，左13mmHgで，右眼の前房が5.8mmと深く，フィブリンを伴う前房出血があった。隅角は正常所見であった。右眼底は透見不能，左眼底には近視性変化があった。眼軸長は右33.57mm，左31.05mmであった。超音波検査で右眼に全網膜剝離があった。右眼に水晶体摘出術と硝子体手術を行い，乳頭下方に裂孔があり，網膜と硝子体間に広範な癒着があった。網膜は復位し，最終的に0.3の視力が得られた。高度近視眼での網膜剝離が前房出血で発見された1例である。

Abstract.　A 65-year-old female presented with sudden ocular pain and visual loss since 3 days before. Her visual acuity was hand motion right and 0.8 corrected by-15 diopters left. The intraocular pressure was 6 mmHg right and 13 mmHg left. The depth of her right anterior chamber was 5.6 mm. The right eye had hyphema with fibrinous exudate. The chamber angle appeared normal. The left fundus showed myopic changes. The axial length was 33.57 mm right and 31.05 mm left. Echography showed total retinal detachment in the right eye. During vitreous surgery and lens extraction,a retinal break was detected inferior to the optic disc. There was extensive vitreoretinal adhesion. The retina became reattached resulting in the final visual acuity of 0.3. This case illustrates that hyphema may lead to detection of retinal detachment in a high myopic eye.
