| Popis: | Purpose To evaluate the topographic three-dimensional mapping of retinal elevation in central serous chorioretinopathy using the Heidelberg Retina Tomograph and to correlate the measured parameters with the fluorescein angiographic findings. Methods Seventy-six consecutive patients with central serous chorioretinopathy (63 men, 13 women), between 26 and 54 years of age, were examined to identify areas of neurosensory retinal detachment and fluorescein leakage. In areas of retinal detachment, the parameters measured were the area, volume, maximal height, and diameters of the retinal elevation, which were statistically analyzed, and the correlations between these parameters were evaluated. Results Mean ± SD area of elevation was 9.6 ± 5.22 mm 2 (range, 2.7 to 21.5 mm 2 ); mean volume was 1.16 ± 1.3 mm 3 (range, 0.11 to 4.73 mm 3 ); mean maximal height was 238 ± 108 μm (range, 97 to 450 μm); mean x-axis was 3.4 ± 1.1 mm (range, 1.6 to 5.6 mm); and mean y-axis was 3.03 ± 0.98 mm (range, 1.6 to 4.7 mm). Most of the retinal elevations were oval (the x-axis longer than the y-axis); the maximal height was in the geometric center in the smaller blebs and below the geometric center in the larger blebs. There were statistically significant correlations between area, volume, and height of the sensory elevation. No correlation was found between the location and the shape of leakage on fluorescein angiography and the Heidelberg Retina Tomograph measurements. Conclusions Confocal laser tomography is potentially useful as a noninvasive diagnostic technique for quantitative measurements of the neurosensory retinal detachment in central serous chorioretinopathy. |
