Purpose: To describe a case of Ellis–van Creveld syndrome with concomitant Usher syndrome. Methods: A 24-year-old lady with a diagnosis of Ellis–van Creveld syndrome came to our attention in 2015 complaining of nyctalopia. She underwent yearly ophthalmologic examinations, including visual acuity, dilated fundoscopy, optical coherence tomography and colour fundus photography. Results: On the day of her first examination, her visual acuity was 20/20, whereas fundus examination revealed diffuse peripheral retinal atrophy with pigmented bone spicules, waxy pallor of the disc and macular sparing in both eyes, compatible with retinitis pigmentosa. Due to the severe retinitis pigmentosa phenotype for the age and the concomitant neurosensory hearing loss, ancillary electrophysiological and genetic tests were requested. At the end of follow-up, visual function remained stable, with electroretinogram tests confirming the peripheral dysfunction. Interestingly, next generation sequencing test revealed a mutation in USH2A gene, suggestive of an overlapping Usher syndrome. On optical coherence tomography angiography, all plexuses appeared altered, with some degree of impairment also in the choriocapillaris of the spared macula. Conclusion: Our report emphasizes the advantage of new genetic tests to investigate atypical presentations of known retinal disorders found in syndromic settings. In addition, we speculate that the underlying ciliopathy might possibly aggravate the phenotype of this case of Usher syndrome.

Abstract Objective To predict the visual prognosis of cataract surgery in patients with retinitis pigmentosa by measuring ellipsoid zone (EZ) width using spectral-domain optical coherence tomography. Methods This retrospective study included patients with retinitis pigmentosa who underwent uncomplicated cataract surgery between December 2017 and June 2020. Preoperative best-corrected visual acuity (BCVA) and the best postoperative BCVA during follow-up were collected. EZ width was measured on preoperative cross-sectional optical coherence tomography images along the horizontal/vertical meridian through the fovea. Results Thirty-eight eyes of 38 patients (22 female; mean [±standard deviation] age, 62.1 ± 11.8 years) were included. The median preoperative logarithm of the minimum angle of resolution BCVA of 0.52 (range, 0.00–3.00) significantly improved to 0.07 (range, −0.18–3.00) after surgery (P < 0.001). On preoperative spectral-domain optical coherence tomography images, the median horizontal, vertical, and average EZ widths were 783 (range, 0–9837), 761 (range, 0–10 250), and 769 (range, 0–10 043) μm, respectively. Postoperative BCVA significantly correlated with the horizontal (r = −0.784, P < 0.001), vertical (r = −0.777, P < 0.001), and average EZ widths (r = −0.777, P < 0.001). The area under the receiver operating characteristic curve for the ability of the horizontal, vertical, and average EZ widths to discriminate eyes with and without postoperative BCVA ≤ 0.3 was 0.971, 0.960, and 0.963, respectively, with best cut-off values of 513, 608, and 515 μm, respectively. Conclusions EZ width measurement can help predict the visual prognosis of cataract surgery in patients with retinitis pigmentosa. A preferable visual acuity prognosis can be expected in patients with an EZ width of approximately 600 μm.

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.
