荧光眼底血管造影晚期视乳头缘晕轮观察

The late peripapillary halo of fundus fluorescein angiography

目的探讨荧光眼底血管造影(FFA)晚期视乳头缘晕轮(LPH)与视乳头周围脉络膜的关系。方法从随机抽出中心性浆液性脉络膜视网膜病变(CSC)患者FFA图像清晰、包含完整的视乳头30只眼中,读出LPH的形状、视乳头周围脉络膜着色、巩膜环/或弧。结果有LPH 29只眼,鼻侧弧形1只眼,环形14只眼,上极或/及下极荧光较淡14只眼。在29只眼LPH中,有巩膜环或弧25只眼,其中巩膜环4只眼,颞侧弧7只眼,上或/及下极不清14只眼。有视乳头颞侧脉络膜着色20只眼,与LPH融合成一体11只眼,其中7只眼LPH的荧光亮度更强,4只眼的荧光亮度一致;9只眼与LPH无相融合。结论LPH是视乳头周围脉络膜渗漏的学说证据不足。

Objective To study the relationship between the late peripapillary halo （LPH） and the choroid of optic papilla＇ s circumference with fundus fluorescein angiography （FFA）. Methods 30 eyes with central serous chorioretiopathy （ CSC ） , which had the integrity discus opticus in the clear fudus fluorescein angiogram, were draw out with random. We analyzed the figure of LPH, the pigmentation of the parapapillary choroid, the sclera annulus or ace. Results There were 29 eyes with LPH, including leye with ace on nose side, 14 eyes with annular shape, and 14 eyes with unclear fluorescence on upper side or/and lower side. 25 eyes with the sclera annulus or ace were found among those 29 eyes. And among those 25 eyes, there were 4 eyes with the sclera annulus, 7 eyes with the temporal side ace, 14 eyes with unclear upper side or/and lower side. On the other hand, 20 eyes had pigmentation on the temporal side choroids, including lleyes amalgamatioo with LPH and 9 eyes without. In these 11 eyes, 7 eyes had higher fluorescence intensity, and the other eyes had the same intensity. Conclusion The theory that LPH came from the leakage of the parapapillary choroid lacked the evidences.
