【摘要】：目的探討高度近視患者視盤旁Zinn-Haller動脈環(huán)的特征。方法回顧分析高度近視眼患者198例(396眼)的眼底彩色照片及眼底熒光血管造影結(jié)果,篩選具有Zinn-Haller動脈環(huán)的患者并結(jié)合視力、屈光度等進行總結(jié)。結(jié)果 24例患者眼底熒光血管造影顯示:Zinn-Haller環(huán)以視盤為中心,位于視盤顳側(cè)視盤邊緣至新月形萎縮弧之間。所有患者均未見完整的Zinn-Haller環(huán)。眼底熒光血管造影動脈前期:隨著脈絡(luò)膜背景熒光的出現(xiàn),即可見視盤顳側(cè)新月形萎縮弧內(nèi)部出現(xiàn)Zinn-Haller動脈環(huán)的顯影;動脈期:當視網(wǎng)膜動脈開始出現(xiàn)動脈前鋒時,Zinn-Haller環(huán)的顯影已經(jīng)完成,其最明顯的部分即位于視盤顳側(cè)萎縮弧內(nèi),此期可清楚分析Zinn-Haller環(huán)與視盤旁血管的位置關(guān)系。眼底熒光血管造影靜脈期可見Zinn-Haller環(huán)完全顯影,其走行形態(tài)非規(guī)則環(huán)形,可見迂曲轉(zhuǎn)角,部分患者甚至呈鋸齒狀走行。結(jié)論 Zinn-Haller環(huán)在不同患者中存在解剖位置及形態(tài)分布上的差異,這些差異可能成為缺血性視神經(jīng)病變、青光眼等視神經(jīng)病變的解剖學(xué)及生理學(xué)基礎(chǔ)。
[Abstract]:Objective to investigate the characteristics of Zinn-Haller arterial ring in patients with high myopia. Methods the fundus color photographs and fundus fluorescein angiography (FFA) of 198 patients with high myopia were retrospectively analyzed. The patients with Zinn-Haller arterial ring were selected and summarized with visual acuity and diopter. Results the fundus fluorescein angiography of 24 patients showed that the circumferential circumference of the 1: Zinn-Haller circle was centered on the optic disc between the edge of the temporal lateral disc of the optic disc and the crescent atrophy arc. No complete Zinn-Haller ring was found in all patients. In the prearterial phase of fundus fluorescein angiography (FFA): with the appearance of choroidal background fluorescence, the Zinn-Haller arterial ring could be seen in the temporal atrophic arc of the optic disc. Arterial phase: the development of Zinn-Haller ring was completed when the front of retinal artery began to appear. The most obvious part was located in the temporal atrophy arc of optic disc. The relationship between the Zinn-Haller ring and the para-optic vessels could be clearly analyzed at this stage. In fundus fluorescein angiography (FFA), the Zinn-Haller loop was completely developed, with irregular circular pattern and tortuous turning angle, and some patients even showed sawtooth pattern in the vein phase of fundus fluorescein angiography (FFA). Conclusion there are differences in anatomical location and morphological distribution of Zinn-Haller ring in different patients. These differences may be the anatomical and physiological basis of ischemic optic neuropathy, glaucoma and other optic neuropathy.
