PURPOSE: To report the morphological and clinical features of a case of retinitis pigmentosa with large choroidal excavation.
METHODS: The patient underwent a complete ophthalmologic examination including best-corrected visual acuity assessment, anterior segment and dilated fundus examination and spectral-domain optical coherence tomography.
RESULTS: A 41-year-old woman affected by retinitis pigmentosa with genetic confirmation with mutation in RDH12 gene had a best-corrected visual acuity of 20/50 in both eyes. Dilated fundus examination revealed waxy pallor of the optic disc, diffuse narrowing of the retinal arterioles and a generalized retinal pigment epithelium mottling with bony spicule associated with diffuse retinal atrophy. At the posterior pole, an extended bilateral chorioretinal atrophy was evident with a partial sparing of the macular area. On spectral-domain optical coherence tomography, a bilateral large choroidal excavation could be clearly detected and it was associated with a diffuse retinal thinning at the posterior pole and a partial sparing of the fovea.
CONCLUSION: Large choroidal excavation has been rarely reported. Although the pathogenetic mechanisms leading to the formation of large choroidal excavation are still a matter of debate, a combination of primary degenerative-inflammatory factors could be retained responsible for the large choroidal excavation development.
