Detection of shallow detachments in central serous chorioretinopathy

Abstract

Purpose: To study the correlation between symptoms, clinical findings, fundus photographic morphology, and optical coherence tomography in patients with symptoms of central serous chorioretinopathy, but ambiguous biomicroscopic findings and no late-phase fluorescein angiographic leakage.

Methods: Biomicroscopic slit-lamp examination, greyscale digital fundus photography in red-free illumination, fundus fluorescein angiography, optical coherence tomography, and focal retinal argon laser photocoagulation. Seven consecutive patients aged 32-69 years, of whom four received focal retinal photocoagulation treatment.

Results: All patients demonstrated a shallow serous detachment on optical coherence tomography. After treatment the detachment resolved, as did the relative scotoma, the prolonged dark adaptation, and the dyschromatopsia. Micropsia was markedly reduced in all, but not completely eliminated in two of the patients.

Conclusion: Patients with central serous chorioretinopathy may have shallow foveal detachments that can only be detected by optical coherence tomography, whereas clinical and angiographic signs of detachment may be missing. Classical symptoms coupled with a normal or only mildly reduced visual acuity are highly indicative of the presence of a serous neuroretinal detachment, but fluorescein angiography is necessary to establish the diagnosis and the target for treatment.
