<正>0引言近年来,对于一些常见的眼表疾病尤其是角膜病变的治疗,大都采取药物治疗或者手术治疗的方法,但像各种化学烧伤导致角膜大面积剥脱,患者眼部炎症及刺激症状明显,不宜行一期手术治疗;大植片的角膜移植术后及大型翼状胬肉切除术后角膜上皮愈合困难等病症,单纯用药

AIM:To study dynamic changes of glycosylated hemoglobin and retinal oscillatory potentials in diabetic retinopathy(DR) .·METHODS:Ophthalmoscope examination was used to screen patients with typeⅡ diabetes. In this study,clear phases was limited by fundus fluorescein angiography(FFA) . Each patient of three-year period regularly measured glycosylated hemoglobin six times and the retinae potentials two times. The final tests were combined with FFA,and the results were analyzed.·RESULTS:When HbA1c level was controlled between 4.99%±0.58%,it could be used as the safety reference value for prevention of occurrence and development of retinopathy;HbA1c level continued in 9.77%±1.57%,the progress of DR speeded up significantly;the total amplitude of retinal oscillatory potentials(Op) decrease <10.6±4.9μV might be taken as stable reference value;amplitude of Op overall decrease >31.6±9.7μV might be used to predict the occurrence of DR or DR progression.·CONCLUSION:Combination of HbA1c and Op can predict the development of DR.

目的探討阿托品和雙星明在青少年散瞳驗光中的應用價值.方法對82例青少年屈光不正患者,按年齡分為5歲～12歲及12歲～18歲兩組,均行阿托品和雙星明雙重散瞳前後電腦驗光,對其進行對比分析.結果 (1)球鏡值:散瞳前後電腦驗光,兩種藥物、兩組病人之間均有顯著差别;阿托品與雙星明之間又有顯著差别,P值均小于0.05.(2)柱鏡值:散瞳前後電腦驗光,兩種藥物、兩組病人之間,阿托品與雙星明之間均無顯著差别,P＞0.1.(3)柱鏡軸:散瞳前後或使用不同藥物,散光值＜1.50D的患者,電腦驗光檢測,柱鏡軸均有較大差别;散光值≥1.50D的患者,電腦檢測其軸位则較準確.結論 對于患有遠視或近視的青少年,仍以阿托品散瞳驗光較為準確.對于單純散光患者,則無需散瞳.

目的探讨翼状胬肉切除术前及术后角膜曲率的改变.方法随机选择鼻侧胬肉40例,分为2组.侵犯角膜≤2.5 mm为第1组,15例;≥3 mm为第2组,25例.两组均行术前及术后视力、角膜曲率和电脑验光检测,进行对比分析.结果视力:第1组术前术后相差0.09,第2组0.23.角膜曲率:垂直径均大于水平径,其差值:第1组术前术后相差0.77KS,第2组4.46 KS.散光值:2组均为远视散光,第1组散光值术前术后相差+0.4 DC,第2组+3.3 DC.结论胬肉可使角膜曲率改变.胬肉侵犯角膜≤2.5 mm时,切除胬肉视力提高不明显;侵犯角膜≥3 mm时,切除胬肉视力明显提高.
