FOOTPRINT INFRA-RED SIMULATING ACUTE MACULAR NEURORETINOPATHY: THE TOPSY-TURVE VALSALVA

Introdução / Purpose

The Valsalva-retinopathy is frequently a benign transient incident and prior observations with noninvasive imaging have detected blood vary size hemorrhages through different retinal layers spread on fundus pole and also within the particular Henle fiber layer trail. There has been only few reports of occurrence in concomitant, simulating or as a trigger of acute macular neuropathy by multimodal imaging findings on particular deep vascular complex.

Material e Método / Methods

This paper describes a 32-year-old man with unilateral central blurred vision just after handstand push-up exercise. The patient underwent ophthalmic examination including multimodal evaluation with color fundus retinography, fluorescein angiography, near-infrared reflectance scanning laser ophthalmoscopy, blue autofluorescence and enhanced-depth imaging spectralis B-scan optical coherence tomography (EDI-SBOCT).

Resultados / Results

Herein, we present a case of Valsalva manoeuvre presenting HFLH parafoveal clusters simulating acute macular neuroretinopathy on SD-OCT and near-IR features, which the latter was named “COUGAR SIGN” and possible predict benign resolution followed through two months after spontaneous resolution.

Discussão e Conclusões / Conclusion

These findings suggest a particular characteristic mark on near-infrared (“cougar footprint”) that may predict a benign clinical recovery with anatomical outer retinal layers retrieval after short time follow-up.
