Summary
Three-dimensional optical coherence tomography (OCT) with an OCT-ophthalmoscope noninvasively visualizes retinal pigment epithelium (RPE) changes in central serous chorioretinopathy (CSC). This technology accurately identifies leakage points, aiding in CSC diagnosis and management.
Area of Science:
- Ophthalmology
- Medical Imaging
- Retinal Diseases
Background:
- Central serous chorioretinopathy (CSC) is a condition affecting the retina.
- Accurate identification of leakage points is crucial for CSC diagnosis.
Purpose of the Study:
- To evaluate three-dimensional optical coherence tomographic (OCT) findings at fluorescein angiography leakage sites in CSC using an OCT-ophthalmoscope.
Main Methods:
- Twenty-seven eyes of 26 patients diagnosed with CSC were examined using an OCT-ophthalmoscope.
- Transverse (C-scan) and longitudinal (B-scan) OCT images were correlated with fundus and fluorescein angiography findings.
Main Results:
- Transverse OCT scans revealed serous retinal detachment in all eyes and irregular retinal pigment epithelium (RPE) lesions in 96% of eyes.
- Longitudinal scans showed RPE detachment (PED) in 63%, RPE layer protrusion in 19%, and rough RPE in 15% of eyes, correlating with fluorescein leakage sites.
Conclusions:
- The OCT-ophthalmoscope facilitates easy and noninvasive detection of morphologic changes at dye leakage points in CSC.
- This imaging modality aids in understanding the structural abnormalities associated with CSC.
