Characteristics of punctate inner choroidopathy complicated by choroidal neovascularisation on Multispectral Imaging in comparison with other imaging modalities

ABSTRACT

Purpose

To describe the characteristics seen on multispectral imaging (MSI) in patients with punctate inner choroidopathy (PIC) and choroidal neovascularisation (CNV) and compare the findings with current standard multimodal imaging techniques.

Methods

This is a retrospective observational case series of 10 patients with PIC complicated by CNV that underwent multimodal retinal imaging examinations.

Results

Twelve eyes of 10 patients were included. CNV was identified in 11 of the 12 eyes (91.7%) by MSI with nodular or trunk-like hyperreflectance on retinal oxy/deoxyhemoglobin map. MSI revealed choroidal vasculature around CNV in 91.7% eyes and pathological changes including retinal pigment epithelial atrophy and melanin disruption of punctate lesions in all eyes.

Conclusion

MSI helps in noninvasively detecting CNV in PIC patients and observing associated changes in choroidal vasculature. This imaging technique is also a promising tool for better tracking pathological changes of PIC lesions complementary to current standard multimodal imaging modalities.
