Indocyanine green angiography in ocular contusion / 中华眼底病杂志

ABSTRACT

Purpose To observe the changes of choroidal circulation and the retinal lesions caused by ocular contusion with indocyanine green angiography (ICGA). Methods ICGA examination was performed on 30 cases (30 eyes) of various traumatic condition in conjunction with fundus fluorescein angiography (FFA). Results FFA of 19 cases (63.3%) showed the hypofluorence in quadrant or whole disc in accordance with the area of delayed filling of choroid. Twenty six cases (86.2%) showed defected choroidel perfusion in ICGA,among them 16 cases showed localized delayed perfusion, in which the shortest perfusion time was 1 min 50 s and the longest time was 5 min.43 s,and 10 patients showed localized perfusion defect,and reversed filling time of retinochoroid vessels in 6 patients. Five cases (16.6%) had delayed filling time in both choroidal and central retinal vessels. Damage of retinal pigment epithelium was found in the areas of choroidal abnormal perfusion. Conclusion ICGA combined with simultaneously FFA, is valuable in evaluating blunt injury of the ocular fundus and beneficial to its diagnosis and treatment.
