Objectives. To demonstrate the usefulness of “en-face” Spectral Domain Optical Coherence Tomography (SD-OCT) combined with Fluorescein Angiography (FA) in the investigation of peripapillary intrachoroidal cavitation. Materials and Methods. A 72-year-old man followed for primary open-angle glaucoma (POAG) for 4 years was referred for an asymptomatic “peripapillary lesion.” A full ophthalmological examination and conventional imaging of the retina were done. FA, Indocyanine Green Angiography (ICG-A), and SD-OCT using the “en-face” technique were also performed. Results. Best-corrected visual acuity (BCVA) was 20/25 both eyes. Slit-lamp examination revealed no abnormalities of anterior segment. Intraocular pressure (IOP) was normal. Fundus examination showed a triangular yellow-orange thickening at the inferior border of both optic nerves. FA showed early hypofuorescence of the lesion and progressive staining without any dye pooling. SD-OCT with “en-face” technique showed an intrachoroidal hyporefective space resembling a cavitation below the retinal pigment epithelium (RPE). Conclusions. “En-face” SD-OCT and FA are valuable techniques for the diagnosis of peripapillary intrachoroidal cavitation associated with myopia. Pathophysiological insights regarding SD-OCT fndings and angiography behavior are ofered. 1. Introduction Te peripapillary detachment of the retinal pigment epithe- lium (RPE) and retina is one of the disorders that may be observed in myopic eyes. It was frst described by Freund et al. [1] on Optical Coherence Tomography (OCT) as a localized RPE detachment around the optic disc. Tey also called it peripapillary detachment in pathologic myopia (PDPM). Toranzo et al. have renamed this abnormality “peripapillary intrachoroidal cavitation,” fnding that this lesion was located inside the choroid and that the underlying RPE and retina were normal [2]. “En-face” OCT imaging is a novel technology that enhances sensitivity in the detection and follow-up of many disorders of the posterior pole. It allows earlier detection and ofers deep insight into the understanding of mecha- nisms underlying retinal lesions [3–5]. We hereby present a case of peripapillary intrachoroidal cavitation and describe the features found on Spectral Domain Optical Coherence Tomography (SD-OCT) using the “en-face” technique. We also present a pathophysiological explanation for the under- lying features found on Fluorescein Angiography (FA) and Indocyanine Green Angiography (ICG-A). To the best of our knowledge, no explanation has been ofered in the literature regarding the angiographic behavior. 2. Case Report A 72-year-old man was referred for a peripapillary “lesion” evaluation. He has been followed for a primary open-angle glaucoma (POAG) for the past 4 years and treated with latanoprost 1 drop daily. His medical history was unremark- able. At presentation, his best-corrected visual acuity (BCVA) was 20/25 in both eyes with the following refraction: -2.00 (-1,00 × 90 ∘ ) in the right eye (OD) and -2.50 (-1,00 × 100 ∘ ) in the lef eye (OS). Slit-lamp examination revealed normal anterior segment in both eyes, and the intraocular pressure (IOP) taken with Goldmann applanation was 11 mmHg OD Hindawi Publishing Corporation Case Reports in Ophthalmological Medicine Volume 2015, Article ID 890876, 5 pages http://dx.doi.org/10.1155/2015/890876
