DESIGN: Observational case report. METHODS: A 12- year-old boy presenting with gyrate atrophy of the choroid and retina underwent ophthalmologic, clinical, and laboratory tests. RESULTS: Plasma ornithine levelwas 735 μ mol/l. Fluorescein angiography showed bilateral hyperfluorescence involving the central region of the macula. Optical coherence tomography (OCT) disclosed bilateral intraretinal cysts areas of low reflectivity with occasional high-signal elements bridging the retinal layers and intraretinal thickening. CONCLUSIONS:Both fluorescein angiography and OCT were helpful to confirm the diagnosis of macular involvement as a complication of gyrate atrophy of the choroid and retina in a patient who presented without any clinical evidence of cystoid macular edema, except a decrease in visual acuity.展开更多

DESIGN: Prospective observational case series. METHOD: Optical coherence tomography (OCT) and high-resolution ultrasonography with a 20-MHz immersion p robe were performed bilaterally in 10 patients, of whom 5 were affected by unila teral active CSC and 5 by unilateral cystoid macular edema (CME). Ten age-match ed control subjects were also investigated. RESULTS: Both OCT and high-resoluti on ultrasonography showed a macular elevation in eyes with CSC and CME. High-re solution ultrasonography has shown evidence of a nonechogenic linear band under the retinal pigment epithelium in patients affected by CSC. This could be found in neither patients with CME or in control subjects. CONCLUSION: Highresolution ultrasonography can detect a nonechogenic space consistent with hyperpermeabilit y of choroidal capillaries in eyes with active CSC. Shadowing by an altered reti nal pigment epithelium cannot be ruled out, however.展开更多
