Multimodal evaluation of hemorrhages within intraretinal cystoid spaces in a blood-fluid level presentation.

Abstract

INTRODUCTION:

We describe characteristic findings on multimodal evaluation and the features of hemorrhage within a foveal cystoid space in a patient presenting cystoid macular edema secondary to Branch Retinal Vein Occlusion (BRVO).

CASE DESCRIPTION:

We report a case of a 64-year-old diabetic male patient presenting gradual blurry vision in the left eye. Fundoscopic findings were suggestive of BRVO, such as hard exudates and mild venous engorgement superotemporally and diffuse macular intraretinal hemorrhages. In the foveal area, there was cystoid edema with blood-fluid level (BFL) inside one of the cystoid spaces. Retina multimodal evaluation, including color, blue filter, and red-free fundus photography, fluorescein angiography, fundus autofluorescence, and spectral-domain optical coherence tomography (SD-OCT) B and C scan imaging, confirmed blood within foveal cystoid space. The patient underwent antiangiogenic therapy with significant improvement of macular edema and reduction of the cystoid space after 3 months. In addition, there was a resolution of visual symptoms. The cystoid space previously partially filled with blood, persisted, despite presenting smaller volume and medium reflectivity in the SD-OCT.

CONCLUSIONS:

Multimodal evaluation of blood-fluid level within foveal cystoid space in patients with BRVO has not been described previously. Identification of this sign may support the diagnosis of retinal vein occlusion in doubtful cases and further studies must be carried out to establish if the presence of BFL correlates with visual outcomes.
