Presentation transcript:

Fig. 3. Selective ophthalmic artery angiogram Fig. 3. Selective ophthalmic artery angiogram. (A-D) In hyaluronic acid-injected patients, no mechanical obstruction is visible in the supratrochlear or supraorbital branch, while blood flow to the retina and the choroid is compromised. (A and D) Obstruction was visible in two patients at small branches of the second segment of ophthalmic artery including the posterior ciliary branch (arrow). (B and C) However, it could not be clearly delineated in the other two patients. (E-G) In autologous fat-injected patients, a large filling defect is visible in the proximal part of ophthalmic artery (arrow). Blood flow is compromised thereafter. (H) Schematic drawings of the vascular anatomy in selective ophthalmic artery angiogram. The lighter lines indicate the optic nerve and the posterior wall of the eye ball. Presumed obstruction level is shown as dashed circle (autologous fat) or lined circle (hyaluronic acid). Case numbers are identical to those in Table 1. Fig. 3. Selective ophthalmic artery angiogram.
