RESUMO
PURPOSE: To describe the syndromic, clinical, and retinal findings of a patient with an extremely-rare genetic condition known as Hardikar Syndrome (HS) with presentation of optical coherence tomography (OCT), fundus autofluorescence (FAF), fluorescein angiographic (FA), and indocyanine green angiographic (ICG) findings. METHODS: Clinical course was detailed and followed over time with examinations and multimodal imaging. PATIENT AND RESULTS: A 17-year-old patient with HS was referred for possible retinitis pigmentosa. Dilated fundoscopic examination revealed large, multifocal cauliform patches of chorioretinal retinal pigment epithelium (RPE) changes with RPE drop-out involving the macula and periphery in both eyes. Additionally, an inactive choroidal neovascular membrane (CNVM) was present in the left eye. Multimodal imaging with OCT, FAF, FA and ICG correlated with the clinical findings of focal patches of chorioretinal degeneration in both eyes. Additionally, an anomalous finding of the superior retinal arterial vessels filling in tandem with the choroidal was present in the left eye. The patient's clinical findings were consistent with HS, and genetic testing with whole exome sequencing revealed a pathogenic mutation in the MED12 gene, confirming diagnosis. DISCUSSION AND CONCLUSIONS: HS is associated with RPE degeneration, creating focal patches of pigmentary chorioretinal atrophic lesions. Vision loss can occur due to the development of CNVMs. We recommend close evaluation and follow-up for HS patients with multimodal retinal imaging.
RESUMO
PURPOSE: To describe a case of chronic pediatric retinal detachment with multiple macrocysts, its surgical management, and a review of the literature. METHODS: Case report with fundus photography and optical coherence tomography. RESULTS: We describe a case of an asymptomatic, 11-year-old boy with a chronic rhegmatogenous retinal detachment with multiple peripheral macrocysts. The patient had counting fingers visual acuity on presentation. The detachment was successfully surgically repaired with scleral buckling, subretinal fluid drainage, cryotherapy, and a SF6 tamponade. At the 12-month follow-up, the retina remained attached with improvement of visual acuity to 20/100 with resolution of the cysts. Optical coherence tomography revealed loss of macular ellipsoid zone. Genetic testing revealed a heterozygous dominant COL11A1 mutation. CONCLUSION: To the authors' knowledge, this is the first reported case of chronic retinal detachment presenting with multiple peripheral macrocysts in a pediatric patient with Stickler syndrome. More research is needed into the cause and significance of retinal macrocysts, particularly in the pediatric population.
