Photoreceptor assessment in focal laser-treated central serous chorioretinopathy using adaptive optics and fundus autofluorescence.

This study analyzed cone density, cone mosaic, and fundus autofluorescence (FAF) images in patients with focal laser-treated central serous chorioretinopathy (CSC).Observational case series.Forty-two eyes of 21 patients with unilateral treated CSC and bilateral best-corrected visual acuity of 1.0 (decimal fraction) were included. FAF and cone mosaic images were obtained in all patients with an adaptive optics fundus camera. Densities were recorded at 20 points throughout the macula, and choroidal thicknesses were measured.Mean choroidal thicknesses were 419.95 ±â€Š110.33 µm in normal eyes, 459.09 ±â€Š90.07 µm in eyes with active CSC, and 438.61 ±â€Š107.57 µm in treated eyes. The highest density of cones in healthy eyes was 38146 cones/mm, with a 5.66-µm intercellular space (IS), at 700 µm temporal to the center. In eyes with treated CSC, the highest density was 32749 cones/mm, with a 6.13-µm IS, at 500 µm nasal to the center. In all quadrants, median values of maximum cone density were significantly higher in healthy eyes (P = .02, P = .003, P = .0001, and P = .001). Three types of lesions were identified on FAF and were correlated with those on cone mosaic images. Strong correlations were detected between the presence of hypoautofluorescent lesions on the first FAF image and a greater difference between maximum values of photoreceptor density (r = 0.46, P = .03), as well as between the presence of hypoautofluorescent lesions and the duration of pathology (r = 0.68, P < .001).The presence of hypoautofluorescent lesions and the duration of pathology were negative prognostic factors in CSC. Laser treatment could prevent photoreceptor loss.

Giant and multiple cardiac papillary fibroelastomas masquerading as acute cerebrovascular events.

Cardiac papillary fibroelastomas are rare benign cardiac tumors. Their clinical significance results from their very high propensity for embolization. We present two such cases, which are rare regarding the size and multiplicity of these tumors.
