Quality of vision: A consensus building initiative for a new ophthalmologic concept.
PURPOSE: Many studies have addressed the quantification of visual acuity, and the conventional method of measuring it has so far demonstrated serious limitations. Vision testing requires new methods that can more precisely express the quality of vision as perceived by the patient. METHODS: This study employed the Delphi method of consensus building. Concepts associated with quality of vision (QoV) were identified by a board of experts and proposed to participating specialists in two subsequent questionnaires. Upon receipt of the completed questionnaires, the replies were classified to determine the building blocks of a consensus. RESULTS: By analyzing the replies to the two questionnaires, the authors determined the key elements of QoV on which a consensus was found among the respondents. CONCLUSIONS: A consensus was reached on the opinion that the quantification of visual acuity by traditional means is inadequate for investigating QoV. Although visual acuity is still a basic element for testing, the experts believe that contrast sensitivity, reading speed, and microperimetry are additional parameters necessary for quantifying QoV. The use of a psychometric questionnaire on visual function could allow a better interpretation of visual impairment.

Fluorescein angiography and indocyanine green angiography for identifying occult choroidal neovascularization in age-related macular degeneration.
PURPOSE: To assess whether fluorescein angiography (FA) alone without indocyanine green angiography (ICGA) can identify and localize occult choroidal neovascularization (CNV) in age-related macular degeneration (ARMD). METHODS: Seventy-nine eyes of 77 consecutive patients with occult CNV were evaluated independently by two skilled physicians at first with FA alone and then with FA combined with ICGA by fundus camera. RESULTS: The agreement between FA and ICGA was 73% and 68% for the two physicians (K=0.585 and 0.512, respectively). The first operator correctly identified 20/27 as plaque CNV; six had different sizes and locations. The second operator identified 25/30, with one mistaken for size and location. For focal CNV the first operator identified 34/39, and the second one 23/35. CONCLUSIONS: Comparing the FA results with ICGA, CNV was correctly identified in about 60% of cases. Therefore, ICGA should be considered an indispensable diagnostic test to identify the presence, the type, and the location of occult CNV.
