To determine the epidemiological, clinical and instrumental characteristics in patients with presumed polypoidal choroidal vasculopathy.
Department of Ophthalmology of the South Ural Medical University
The study included 31 patients (31 eyes), examined at the Ophthalmology Department of South Ural Medical University, Men - 11 , women - 20 , the average age - 69 ± 8 years. All patients diagnosed presumed PCV. All patients were performed ophthalmoscopy and optical coherence tomography. We evaluated the main features: localization of presumed polypoidal formations , the presence , location and nature of the hemorrhagic component , location, length , height, number of polypoidal formations.
Study of the clinical picture in patients with PCV showed the presence of red-orange nodules at the site of the presumed polypoidal formations: parafoveal -19 eyes (61.3 %), juxtafoveal - 8 eyes (25.8%) , peripapillary - 4 eyes ( 12.9% ) . It is worth noting the presence of hemorrhagic component in 13 eyes (41.9 %). Hemorrhages were local in 9 cases , extensive subretinal hemorrhage were observed in 4 eyes. 9 patients (29%) identified the 'honey exudate' around the affected area. In 18(58.1 %) patients polypoidal formations in the form of local PED localized parafoveal, 8(25.8%) pa-tients - peripapillary and in 5(16.3 %) patients - juxtafoveally . PED length varied from 398 to 1278 mm , height from 138 to 671 microns. In 7(22.6%) patients had several local PEDs associated with PCV ('bola' sign) . In 18 (58.1%) eyes was determined the 'double layer' sign - the average reflectivity material between PED and Bruch's membrane , indicating the polypoidal formation. Neurosensory retinal detachment detected in 18 (58.1%) patients. In all cases, NRD located around the area of PED , reaching the area of parafovea and had length from 351 to 4598 mm, a height of 70 to 311 microns.
The main clinical features of patients with presumed PCV were the presence of red-orange nodules often located parafoveally (61.3 %) and juxtafoveally (25.8% ), presence of subretinal hemorrhagic component (41.9 %) and the presence of 'honey exudate ' (29%). Carrying optical coherence tomography in patients with polypoidal choroidal vasculopathy revealed that most commonly associated with polypoidal formations local PED located parafoveally (58.1 %) and peripapillary (25.8%) , in some cases (22.6%) PED has a multiple character('bola' sign) . 'Double layer' sign identified in 58.1 % of cases. The majority of patients (58.1 %) has been accompanied by neurosensory retinal detachments , localized at the edges of the pigment epithelium detachment .
