Filter by:Aim of the work PIC in pathological myopia has not been well documented due to difficult in diagnosis we conducted this retrospective study to characterize the clinical features of PIC in high myopic eye. - To show the diagnostic criteria of PIC lesions in high myopic patients. - Find out the prevalence of PIC related 'patchy atrophy' - To determine risk factor for developed PIC in a series of highly myopic patients. - Role of PIC in progression of high myopia. - Calculate the progression rate of PIC related lesion, by the size change during follow-up. - Search about complication of PIC in myopia. Patient and Methods This retrospective observational case series study included patients with high myopia who had been examined and followed-up in the High Myopia Clinic of the Tokyo Medical and Dental University. Approval from Ethics Committee of Tokyo Medical and Dental University was obtained, adhering to the tenets of Declaration of Helsinki. Signed informed consent documentation was obtained from all participants. All study participants underwent a detailed ophthalmologic examination at baseline and at each follow-up visit. The examinations included measurements of best-corrected visual acuity (BCVA) using a Landolt C chart, refraction, slit lamp biomicroscopy, biometry for determination of axial length, (IOL Master; Carl Zeiss Meditec Co, Jena, Germany), fundus examination in medical mydriasis, fluorescein angiography, was performed with and colour fundus photography , and assessment of fundus autofluorescence (TRC-50DX; Topcon, Tokyo, Japan) a or the Heidelberg Spectralis HRA system. Swept source Optical coherence tomography (OCT) used in assessment of the RPE and photoreceptors using a (DRI-OCT;Topcon, Tokyo, Japan). As scanning protocols, 9 mm or 6 mm radial with 12 equal meridian scans were performed. The swept-source OCT device has an A-scan repetition rate of 100 000 Hz, and its light source operates in the wavelength range of 1 μm.
To report the long term prognosis in patients with punctate inner choroidopathy (PIC) or multifocal choroiditis (MFC) and associated zonal outer retinopathy (ZOR).
To evaluate the long-term outcome of active choroidal neovascularization (CNV) in punctate inner choroidopathy (PIC) or multifocal choroiditis (MFC) after anti-vascular endothelial factor treatment.
