Purpose To measure the retinal thickness in the macular area and at the typical fundus spots in a patient with birdshot retinochoroidopathy, using the retinal thickness analyzer (RTA), a new image analyzer involving laser-slit biomicroscopy, and to quantify the changes after systemic corticosteroid therapy. Case Report A 54-year-old man with posterior uveitis underwent visual acuity measurement, fluorescein and indocyanine green (ICG) angiographies, optical coherence tomography (OCT) and RTA measurements before and after steroid treatment. Results The thickness at the birdshot spots measured with RTA remained unchanged after treatment, but the thickness at the fovea decreased in both eyes. Fluorescein and ICG angiographies and OCT showed no change with treatment. Conclusions RTA seems a more sensitive method for assessing changes in macula thickness in the course of birdshot retinochoroidopathy and can help document the effect of treatment.
