Choroidal thickness was defined as the vertical distance from outer edge of the hyperreflective RPE to the innermost hyperreflective line of the chorio-scleral interface (vertical white arrow). The thickness of the Haller layer was defined as the distance from the innermost point of the horizontal line of the large choroidal blood vessel to the innermost edge of the highly reflective line of the choroid-sclera interface (short white arrow).
Figure 2 Complete recovery of pigment epithelial detachments at the leakage point
这是1名40岁的男性患者。在疾病发作的渗漏点有1个小的PED。在随访时间内观察到完全恢复。
This is a 40-year-old male patient. There is a small pigment epithelial detachment at the leakage point on disease onset. Complete recovery was observed in the follow-up time.
图3 渗漏点处的PED在13个月的随访时间内持续存在
Figure 3 PED at the leak point persisted during the 13-month follow-up time
This is a 33-year-old male patient. In the 13-month follow-up time, although the subretinal fluid resolved completely, separation between RPE and Bruch membrane could still be seen.
图4 渗漏点处的PED在9个月的随访时间内持续存在
Figure 4 PED at the leak point persisted during the 9-month follow-up time
This is a 39-year-old male patient. By the end of the 9-month follow-up, although the subretinal fluid resolved completely, separation between RPE and Bruch membrane could still be seen.
