INDOCYANINE GREEN VIDEOANGIOGRAPHY OF OCCULT CHOROIDAL NEOVASCULARIZATION - A COMPARISON OF SCANNING LASER OPHTHALMOSCOPE WITH HIGH-RESOLUTION DIGITAL FUNDUS CAMERA

Purpose: To compare the indocyanine green (ICG) angiographic findings of occult choroidal neovascularization (O-CNV) taken by scanning laser ophthalmoscope and high-resolution digital fundus camera. Methods: We examined 100 eyes of 100 consecutive patients with ICG angiographic e vidence of CNV secondary to age-related macular degeneration. All pati ents were diagnosed with O-CNV based on fluorescein angiography. Indoc yanine green videoangiography was carried out using the scanning laser ophthalmoscope and high-resolution digital fundus camera at the same session. Results: Indocyanine green videoangiography revealed well-def ined vessel structure of the O-CNV in 28% of eyes examined by scanning laser ophthalmoscope and in 8% of eyes examined by digital fundus cam era. Well-defined focal spots were demonstrated in 37% of eyes examine d by scanning laser ophthalmoscope and in 52% of eyes examined by digi tal fundus camera. Plaques (well-defined) were found in 13% and 35% of eyes examined by scanning laser ophthalmoscope and digital fundus cam era, respectively. Conclusion: Indocyanine green videoangiography with scanning laser ophthalmoscopy seems to be superior to the digital fun dus camera in delineation of the vessel architecture of O-CNV. Focal s pots and plaques are best detected by digital fundus camera.
