The ultrasonographic manifestation of age-related macular degeneration / 中华眼底病杂志

ABSTRACT

Objective To study the ultrasonographic manifestation character of age related macular degeneration (AMD). Methods The ultrasonographic manifestation of thirty five cases (38 eyes) of AMD diagnosed by fundus fluorescein angiography (FFA) with positive findings of ultrasonic B scan were analysed. Results The ultrasonic appearance of interlamellar transaudient cleft were found in 26 eyes, in which FFA appearance were serous detachment of pigment epithelium and subretinal neovascularization, 5 of them associated with small excavation of choroid, 4 of them associated with strong echo belt at the posterior edge of the interlamellar transaudient cleft in which the FFA appearance was extensive subretinal neovascularization.In another 4 eyes with choroidal hematoma under FFA revealed thin echo light spots in the interlamellar transaudient cleft. There was scar staining in the other 8 eyes in which the ultrasonic appearance showed an unequal thickening of the ocular wall in the posterior pole,unequal echo of interior edge and irregular inner echo. Conclusion The main ultrasonographic manifestation of AMD is the presence of interlamellar transaudient cleft in the thickened ocular wall.
