  • Multimodality imaging features of different properties in multifocal choroiditis

    Objective To observe multimodality imaging features of different properties in multifocal choroiditis (MFC). Methods Twenty-eight patients (51 eyes) with MFC were enrolled in this study. There were 10 males and 18 females. The patients aged from 31 to 49 years, with the mean age of (41.5±0.8) years. There were 23 bilateral patients and 5 unilateral patients. All patients underwent best corrected visual acuity (BCVA), slit-lamp biomicroscopy, indirect ophthalmoscopy, fundus colorized photography, infrared fundus photography, fundus autofluorescence (FAF), fundus fluorescein angiography (FFA) and optical coherence tomography (OCT) examinations. The lesions were classified as active inflammatory lesion, inactive inflammatory lesion, active choroidal neovascularization (CNV) and inactive CNV. The multimodality imaging features of different properties in MFC was observed. Results In fundus colour photography, the boundaries of active inflammatory lesions were blurry, while inactive inflammatory lesions had relatively clear boundaries. Secondary active CNV showed mild uplift and surrounding retinal edema; Secondary active CNV lesions showed mild uplift, retinal edema around the lesion; Secondary non-active CNV had no retinal exudate edema lesions, but had lesions fibrosis and varying degrees of pigmentation. Infrared fundus examination revealed that both active and inactive inflammatory lesions showed a uniform punctate or sheet-like fluorescence. The fluorescence of CNV lesions was not uniform; there was a bright ring around the strong fluorescence. FAF found that active inflammatory lesions showed weak autofluorescence (AF), surrounded by a strong fluorescence ring; inactive inflammatory lesions showed AF loss. Secondary active CNV lesions showed strong AF with a bright ring along the edge, and obscured fluorescence for co-occurred hemorrhagic edema; secondary non-active CNV lesions were strong AF, surrounded by a weak AF ring. FFA revealed that active inflammatory lesions showed weak fluorescence in the early stage, and fluorescence gradually increased in the late stage with slight leakage. Inactive inflammatory lesions showed typical transmitted fluorescence. Fluorescein leakage secondary to active CNV was significant; lesions secondary to inactive CNV showed scar staining. In OCT, the active inflammatory lesions showed moderately weak reflex signals in the protruding lesions under the retinal pigment epithelium (RPE). The inactive inflammatory lesions showed penetrable RPE defects or choroidal scar, it also showed clear RPE uplift lesions with a strong reflection signal. Secondary active CNV showed subretinal fluid retention; secondary non-active CNV showed RPE defects and choroidal scarring. Conclusions Active inflammatory lesions in MFC have blurred boundary, retinal edema and fluorescein leakage in FFA; inactive inflammatory lesions have clear boundary and typical transmitted fluorescence in FFA, and no retinal edema. Secondary active CNV showed subretinal fluid in OCT; and secondary non-active CNV showed RPE defects and choroidal scarring.
