Resultados

77-year-old man that came to the retina department for evaluation of specific unilateral funduscopic findings, after years of complaint of non-quality vision. Medical history with no diabetes nor hypertension. On examination best corrected visual acuity (BCVA) was of 20/20 in the right eye (OD) and 20/40 in the left eye (OS) specially due to a known refractive amblyopia. Concerning ophthalmological history, he went under phacoemulsification in both eyes years ago with no complications, denied other previous ocular treatments whatsoever. Anterior segment examination was normal bilaterally. He underwent complete complementary imaging examination, consisting of broad line fundus imaging (BLFI) true color and red-free fundus and green wave-length autofluorescence. Also submitted to wide-field fluorescein angiography (WF-AGF), and infrared reflectance followed by correspondent study of 12 mm scan of a spectral-domain optical coherence tomography (SD-OCT), complemented by optical coherence tomography angiography (OCT-A). Registrations revealed areas of perifoveolar ischemia as well as extramacular areas secondary to aneurysmal lesions in the middle layer of the inner retina in OD. These findings contributed to the diagnosis of idiopathic aneurysmal telangiectasia.

Discussão e Conclusões

Yanuzzi proposed a division of this entity into two major distinct types: aneurysmal telangiectasia and perifoveal telangiectasia, also known as macular telangiectasia (MacTel) 1 and MacTel 2, respectively. Mactel 1 is a rare condition characterised by retinal telangiectasia as well as micro-aneurysms commonly confined to the temporal half of the macula.Visual loss is mainly caused by cystoid macular edema (CMO) and formation of hard exudates, which are the hallmark features of the disease, believed to be congenital predominantly unilateral, mostly in middle-aged men. So far, there are no records of multimodal analysis with all exams described.
