PG - 427 LID - 10.1186/s12886-021-02197-7 [doi] LID - 427 AB - PURPOSE: To study whether retinal pigment epithelium (RPE) disruption and choroidal hyper-transmission on spectral-domain optical coherence tomography (SD-OCT) are signs of inflammatory neovascularization (CNV) in punctate inner choroidopathy (PIC). METHODS: This is a prospective cohort study. Seventeen patients (18 eyes) were diagnosed as PIC without CNV at baseline. Changes of morphological characteristics including choroidal hyper-transmission, hypo-transmission, RPE disruption, and ellipsoid zone (EZ) damage on SD-OCT were observed and recorded at baseline, 4, 8 and 12 weeks, respectively. The occurrence of CNV was detected by OCTA at each visit. Fisher's exact test was used to compare the relationship with each morphological sign and evaluate the predictable capability of secondary CNV in PIC (PIC+CNV) based on the structure changes on OCT. RESULTS: Among the 18 eyes, a total of 5 eyes (27.8%) developed PIC+CNV subsequently within 4 weeks follow-up. At 4, 8 and 12 weeks of follow-up, RPE disruption and choroidal hyper-transmission were found in all 5 PIC+CNV eyes. The incidence of RPE disruption was significant higher in PIC+CNV eyes compared with PIC eyes (P=0.001). PIC eyes with hyper-transmission had a higher risk for developing CNV compared with those without hyper-transmission (P=1.17x10(-3)). 2 out of 5 PIC+CNV eyes had a choroidal hypo-transmission component adjacent to hyper-transmission zone at 4 weeks of follow-up, and hypo-transmission could be observed in all 5 PIC+CNV eyes at 8 weeks of follow-up. The incidence of choroidal hypo-transmission was significant higher in PIC+CNV eyes than PIC eyes after 8 weeks. EZ damage began to recover at 4 weeks of follow-up and had no significant difference in the PIC eyes and PIC+CNV eyes (P=0.150, 0.196, 0.353). CONCLUSION: The presence of choroidal hyper-transmission and RPE disruption on SD-OCT is associated with the PIC+CNV. SD-OCT imaging facilitates the differentiation and track of the progression of inflammatory lesions and secondary CNV in PIC. CI - (c) 2021. The Author(s).
