Myopic macular pits: a case series with multimodal imaging.

OBJECTIVE

To characterize the multimodal retinal findings of myopic macular pits, a feature of myopic degeneration.

METHODS

A case series of patients with myopic macular pits were studied with multimodal imaging including color fundus photography, fundus autofluorescence (FAF), near infrared reflectance (NIR), spectral domain optical coherence tomography (OCT), optical coherence tomography angiography (OCTA), fluorescein angiography (FA) and indocyanine green angiography (ICG).

RESULTS

Nine eyes of 6 patients with myopic macular pit were examined. Four patients presented with multiple pits and 3 with bilateral involvement. All pits were localized in a region of severe macular chorioretinal atrophy associated with myopic posterior staphyloma. In 3 eyes, the entrance of the posterior ciliary artery through the sclera was noted at the base of the pit. Schisis overlying the pit or adjacent to the pit was identified in 3 patients.

CONCLUSION

Myopic macular pits are an additional rare sign of myopic degeneration, developing in regions of posterior staphyloma complicated by severe chorioretinal atrophy and thin sclera.
