Choroidal osteoma is a choristomatous lesion postulated to be congenital in nature. Described herein is the case of a 16-yearold female presenting with a peripapillary lesion diagnosed as choroidal osteoma on multimodal imaging. Routine fundus photography 18 months before presentation demonstrated a normal retina and choroid without evidence of the lesion. Overall, this report provides evidence that choroidal osteoma may be acquired and not always congenital in origin.

We present a 57-year-old referred reduced visual acuity who was in treatment with paclitaxel for developing metastatic breast adenocarcinoma. Ophthalmoscopic examination, optical coherence tomography, and autofluorescence show the cystoid macular edema, but fluorescein angiography is normal, without leakage of dye in the late times. The patient responds well 8 weeks after stopping antineoplastic. Paclitaxel can cause cystoid macular edema and lifting a recovery both anatomical and functional of the macula.

Objective: The objective of the study was to describe and evaluate the subfoveal choroidal thickness (SFCT) in the fellow eyes of patients with central serous chorioretinopathy (CSC) using swept source optical coherence tomography (SS-OCT). Methods: This was a transversal, retrospective, and observational study. The SFCT was measured in patients with unilateral CSC using SS-OCT. The choroidal thickness in symptomatic and fellow eyes was measured using the attached measuring software in SS-OCT. The SFCT dimension was obtained from the horizontal section under the foveal center from the OCT data and these data were analyzed. Results: The mean age of subjects undergoing imaging SS-OCT was 44.23 years old (standard deviation, 11.57). 30 out of 60 patients (63.3%) were men, and 20 (33.3%) patients had acute clinical disease. The median choroidal thicknesses of the affected eyes were greater than those of the unaffected fellow eyes (P = 0.06). The choroidal thickness measured in 120 eyes of (60 patients) was 421 ?m (interquartile range 352–490), which was greater than the choroidal thickness reported in normal eyes. Conclusions: The measuring of the choroidal thickness using SS-OCT is useful as a non-invasive technique to evaluate the subclinical choroidal abnormalities in CSC.
