Clinical effects of triamcinolone acetonide combined with laser photocoagulation on patients with retinal vein occlusion / 国际眼科杂志(Guoji Yanke Zazhi)

AlM: To observe the effects of the coelomic cavity injection of triamcinolone acetonide ( TA) combined with laser photocoagulation on patients with retinal vein occlusion. METHODS:Fifty-six patients of retinal obstruction with macular edema were accepted from January 2010 to December 2012 in our hospital. All patients received iodized lecithin and Xueshuantong. And, patients with central retinal vein occlusion ( CRVO ) , hemi- central retinal vein occlusion ( hemi-CRVO ) and branch retinal vein occlusion ( BRVO ) treated by TA combined with laser photocoagulation, respectively. Follow-up period was of at least 6mo RESULTS: After the treatment of 1, 3 and 6mo, the central foveal thickness was reduced significantly ( P CONCLUSlON:Basing on the traditional treatment, TA combined with laser photocoagulation is more effective in the treatment of retinal vein occlusion and is worthy of clinical usage.

Analysis of the correlation between autofluorescence and central vision at advanced stage of the classical retinitis pigmentosa / 国际眼科杂志(Guoji Yanke Zazhi)

AIM: To investigate autofluorescence (AF) images of classical retinitis pigmentosa (RP) at advanced stage correlated with central vision. METHODS: Thirty-seven patients (70 eyes) with classical RP at advanced stage were observed. AF imaging was performed using a Heidelberg Retina Angiograph 2 ( HRA-2) scanning laser system with the field 30°, the pixels 1 536×1 536 and pupil diameters >6mm. Some patients underwent automated static peri-metry and the flash electroretinogram(FERG) were performed according to International Society for Clinical Electrophysiology of Vision( ISCEV) standard. RESULTS: All patients were classified as four patterns according to their manifestation of AF they were intact, patchy, solitary island and central hypofluorescence patterns. Different pattern showed different central vision. The data demonstrate high correlation between the central cone function and AF changes of the fundus. There is significant correlation (n= 57, r= 0.385,P＜0.01) between central vision and the AF area and between age and AF area (n= 57, r= -2.67,P＜0.05).CONCLUSION: AF images is valuable to the monitoring of central cone function and in predicting retention of central vision. The changes of AF images correlated with central vision and different pattern showed different vision.
