Summary
High-resolution retinal imaging revealed distinct intraretinal hyperreflective clusters in central serous chorioretinopathy (CSC). These findings offer new insights into the pathophysiology of active and resolved CSC.
Area of Science:
- Ophthalmology
- Retinal Imaging
- Cellular Biology
Background:
- Central serous chorioretinopathy (CSC) is a condition affecting vision.
- Understanding the cellular basis of CSC is crucial for effective treatment.
Purpose of the Study:
- To enhance the understanding of central serous chorioretinopathy (CSC).
- To analyze noninvasive, high-resolution retinal imaging in patients with active and resolved CSC.
Main Methods:
- Employed adaptive optics scanning light ophthalmoscopy (AOSLO) and spectral-domain optical coherence tomography (SD-OCT).
- Utilized a custom AOSLO system for simultaneous confocal and split-detector imaging.
- Created en face OCT views of retinal layers and coregistered them with AOSLO montages.
Main Results:
- Identified three types of intraretinal hyperreflective clusters using AOSLO.
- Type-1 clusters in active CSC showed association with photoreceptor defects.
- Type-2 clusters in reattached areas were stable over 8 months; Type-3 clusters were observed in the inner retina.
Conclusions:
- En face OCT and AOSLO enable precise localization of intraretinal structures in CSC.
- Findings suggest intraretinal hyperreflective foci in CSC are cellular.
- This imaging approach provides deeper insight into CSC pathophysiology.
