中文摘要 | 目的:立體感係因視網膜上形成水平影像分離而產生相對深度之雙眼 視覺,它會受到斜視、弱視、雙眼不等視及未矯正單眼不等視的影響。本研究中, 我們想了解視網膜剝離術後良好貼合病人之立體感表現。病人與方法:我們收集 共30位單眼裂孔性視網膜剝離並成功治療的病人,患眼最終視力大於0.05,並 排除有斜視或弱視的病人。病人接受最佳矯正視力、眼位檢測、及立體感檢查, 包括Titmus、TNO及NTU300"檢查。結果:病人依立體感檢查結果分為三組:不 正常組共3位,佔10.0%;低於正常組共2位,佔7.0%;以及正常組共25位, 佔83.0%。正常組別之術後患眼平均視力為0.8到 0.9,而非正常組別之術後患眼 平均視力為 0.2到0.3。非正常組別之雙眼視力差距較大。年齡較大組別(大於50 歲)之立體感表現較年輕組別為差。術前黃斑部剝離對立體感表現並無明顯差 異。結論:我們的研究結果顯示,視網膜剝離術後良好貼合病人之立體感,受到 術後視力及雙眼視力差異影響。(慈濟醫學2001; 13:151-154) |
英文摘要 | Objecitve: Stereopsis is a binocular perception of relative depth caused by horizontal retinal image disparity. Strabismus, amblyopia, uncorrected anisometropia and ametropia can interfere with it. We tried to determine if and how stereopsis is affected after successful surgery for retinal detachment. Patients and Methods: We collected a total of 30 cases of successfully treated rhegmatogenous retinal detachment. All lesion eyes had final visual acuity above 0.05. Patients with amblyopia and heterotropia were excluded. Best corrected visual acuity (VA), Hirschberg test, prism cover test and stereopsis test including Titmus, TNO and NTU 300" were performed. Results: Patients were separated into three groups according to the results of stereopsis testing: abnormal (3/30 cases, 10.0%), subnormal (2/30 cases, 7.0%), and normal (25/30 cases, 83.0%) group. The mean best corrected VA in the lesion eyes was around 0.8 to 0.9 in the normal group and around 0.2 to 0.3 in the subnormal and abnormal groups. The discrepancy of VA between two eyes was greater in the subnormal and abnormal groups. Older patients (≧50 years old) had worse stereopsis than younger patients. Stereopsis was not significantly affected by preoperative macular involvement. Conclusions: In our study, stereopsis in cases of successfully reattached retinal detachment was influenced by visual acuity of less than 0.2 in the operated eyes and a discrepancy in visual acuity between the two eyes.
