Abstract:
Age-related macular in human retinal results in strict loss and enduring decrease in visual acuity. A lot of medical evidence has shown that macular degeneration, associated with Choroidal neovascularization (CNV), leads to irreversible injure in composition and function of retinal tissue. A new analytical and restorative treatment, scotoma-based photocoagulation (SPB), curdles the affected areas so effectively and timely that it can delay or prevent age-related macular degeneration (AMD). A scanning laser ophthalmoscope (SLO) image is involved and the function and character of scotometry are analyzed. Combining anatomical and pathological features, this paper introduces process of acquiring the image and algorithms of analyzing it. Furthermore, integrate image of retinal is extracted from SLO through feature extraction, special registration and superimposition. The treatment can be applied to clinical diagnosis without great revisions and provide direction for pertinent fields.
