Purpose:
To describe the spectral-domain optical coherence tomography (SD-OCT) findings in a case of Coats' disease, with emphasis on the intraretinal exudates.
Methods:
Case report of a 4.5-year-old girl who presented with total exudative retinal detachment and organized exudates in a stellate configuration. SD-OCT was performed before and after treatment, which included surgical drainage of subretinal fluid and indirect laser application during the surgery.
Results:
At presentation, the SD-OCT showed an elevation of the foveal contour, with thickening of the retina, many exudates and a large quantity of subretinal fluid. Two months after the surgical treatment, SD-OCT revealed a significant reduction in the amount of subretinal fluids, but with persistence of the exudates.
Conclusion:
SD-OCT can be used as an important tool in order to describe the changes in each layer of the retina in Coats' disease. Considering the histopathological findings in Coats' disease, it is reasonable to assume that the exudates accumulate in the outer plexiform layer.
