Abstract Details



Purpose:

To determine the epidemiological, clinical and instrumental characteristics in patients with presumed polypoidal choroidal vasculopathy.

Setting:

Department of Ophthalmology of the South Ural Medical University

Methods:

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.

Results:

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.

Conclusions:

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 .
