Subretinal hyporeflective globule: A novel OCT finding in central serous chorioretinopathy

PURPOSE

To describe the subretinal hyporeflective globule in cases of central serous chorioretinopathy (CSC).

METHODS

A retrospective analysis of consecutive cases of CSC presenting to a tertiary eye care center in eastern India was conducted. Subretinal hyporeflective globules were identified as small globular lesions below the external limiting membrane/ellipsoid zone, but above the RPE layer. They had a hyperreflective border with a hyporeflective core and a clear posterior tail of hyper-transmission.

RESULTS

The present study analyzed 137 eyes of 137 patients. Eighty (58.4%) eyes had acute disease at presentation, 48 (35%) eyes had chronic disease, and eight (5.8%) eyes had resolved CSC. Subretinal hyporeflective globules were seen in 27 (21.8%) eyes, of which choroidal caverns were seen in seven (5.1%) eyes. Twenty-five eyes with chronic CSC and only two eyes with acute CSC had subretinal hyporeflective globules. Three eyes with resolved CSC had subretinal hyporeflective globules.

CONCLUSION

We describe subretinal hyporeflective globule as a novel optical coherence tomography (OCT) finding in cases of CSC and describe its clinical correlates.

Multicolour imaging signatures to diagnose concurrent macular telangiectasia type 2 and macular branch retinal vein occlusion

Concurrent macular telangiectasia type 2 (MacTel) and branch retinal vein occlusion (BRVO) have not been described before and can pose a diagnostic dilemma. The current report highlights the role of multicolour (MC) imaging and blue reflectance (BR) imaging in diagnosing this multi-pathology. A 60-year-old male presented with diminution of vision in the right eye. BR imaging showed parafoveal hyperreflectance, characteristic of MacTel, and hyperreflective parafoveal retinal vessels indicating vascular changes in RVO. MC imaging, particularly the BR component is a promising tool to aide in the diagnosis of concurrent MacTel and BRVO, guiding treatment decisions and prognosticating treatment outcomes.
