Abstract The macula or macula lutea (from Latin macula, ”spot” and lutea, ”yellow”) is an oval-shaped highly pigmented yellow spot near the center of the retina of the human eye. It has a diameter of around 1.5 mm and is responsible for central and colour vision. Age-related macular degeneration (AMD) is the leading cause of blindness in both developed and developing nations in patients older than 60 years . Choroidal neovascularization (CNV) is the creation of new blood vessels in the choroid layer of the eye. Patients with Choroidal Neovascularization present with: painless loss of vision, metamorphopsia, paracentral or central scotoma or apparent change in image size. There are several methods used for diagnosis of CNVM. The most commonly used are FA and the non invasive OCT. The combination of clinical examination, OCT and appropriately timed FA is required to provide the best possible care for some patients Lines of treatment include intravitreal injection of Anti VEGF asa well as other uncommon surgicl intervetion. In our study we aimed to study the relation between macular thickness detected by OCT and lesion size detected by FA Thirty patients underwent full medical history and complete ocular examination including visual acuity , IOP, slit lamp examiation and , fundus examination as well as colour photography , OCT and FFA. 66 At the end of the study we found that there is no significant correlation between macular thickess detected by OCT and lesion diameter detected by FA. |
