網膜静脈分枝閉塞症における硬性白斑と高脂血症

Hard exudates and elevated level of serum lipids in branch retinal vein occlusion

要約　目的：網膜静脈分枝閉塞症における硬性白斑と血中脂質の関係の報告。対象と方法：硝子体手術を行った網膜静脈分枝閉塞症89例89眼を対象とした。男性40例，女性49例で，年齢は平均67.1歳であった。経過中に硬性白斑が生じた12眼と生じない77眼について，諸検査値を比較検討した。結果：年齢，罹病期間，視力，黄斑網膜厚については両群間に有意差がなかった。白斑がある群は，総コレステロール値は有意に高く（p＝0.005），術6か月後の黄斑浮腫の改善が有意に悪かった（p＝0.002）。結論：網膜静脈分枝閉塞症で硬性白斑がある群は，ない群に比べ総コレステロール値が高く，黄斑浮腫の改善が悪かった。

Abstract.　Purpose：To report the relation between hard exudates and serum lipid levels in cases of branch retinal vein occlusion（BRVO）. Cases and Method：This retrospective study was made on 89 eyes of 89 cases who received vitrectomy for BRVO. The series comprised 40 males and 49 females. The age averaged 67.1 years. Hard exudates were present or became apparent in 12 eyes and were absent throughout in 77 cases. Results：There was no difference between the two groups regarding age,duration of BRVO before surgery,visual acuity,or macular thickness. Cases with hard exudates had significantly higher serum levels of total cholesterol（p＝0.005）and showed poorer recovery of cystoid macular edema 6 months after vitrectomy（p＝0.002）. Conclusion：Eyes with BRVO were characterized by higher serum levels of total cholesterol and slower postoperative absorption of cystoid macular edema.
