中文摘要 | 急性挫傷性網膜色素壞死發生於眼鈍傷。受損傷部位主要在視網膜色素之上皮及 視網膜外層。因外傷造成眼介質混濁及色素上皮萎縮出現很快,臨床上較少觀察到急性期變 化。本篇報告兩病例年齡分別為14歲及22歲。外傷後均出現神經盤附近之局部視網膜泛白 變化合併的局部視網膜下積液。螢光眼底攝影可見早期之網膜下螢光滲漏。數日內迅速轉變 成色素上皮萎縮。因未傷及黃斑部視力恢復均理想。直接之機械性傷害可能為較合理之致病 機轉。 |
英文摘要 | Acute contusion necrosis of the retinal pigment epithelium (RPE) can develop after blunt ocular injuries. Beside the RPE, the outer segment of the photoreceptor cell layer is also affected. The lesion may escape diagnosis because of associated damage and its quick progression to RPE atrophy. We present two young patients who had localized whitening of the retina with subretinal fluid adjacent to the optic disc after a blunt ocular injury. Fluorescein angiiography revealed early fluorescein leakage under the affected retina. The lesion showed RPE atrophic change within a few days in both cases. The macula was not involved in either case and the vision remained good. The mechanism may have been related to the direct mechanical effects of the trauma rather than to vascular insufficiency. |
