    Diabetic Maculopathy

    Diabetic maculopathy is the most common cause of visual impairment in patients with diabetes mellitus. Classification Diabetic maculopathy is classified as – Exudative Maculopathy Ischemic Maculopathy Mixed Maculopathy 1. Exudative Maculopathy (Diabetic Macular Edema) It is diagnosed stereoscopically as retinal thickening within 1 disc diameter of the center of the macula using fundus biomicroscopy. To characterize the severity of macular edema and for treatment guidelines, the term clinically significant macular edema (CSME) is used. Macular edema is clinically significant if one of the following conditions is present: Retinal thickening at or within 500 mm of the center of the macula; and/or Hard exudates at or within 500 mm of the center of the macula if associated with thickening of the adjacent retina; and/or A zone or zones of retinal thickening 1 disk area in size, at least part of which is within 1 disk diameter of the macular center. It is more common in type 2 diabetes (Adult

    Central Serous Choroidopathy

    Introduction Central serous chorioretinopathy (CSC) is one of several chorioretinal disorders characterized by serous detachment of the neurosensory retina and ? or the retinal pigment epithelium (RPE). CSC is one of the 10 most common diseases of the posterior segment of the eye and a frequent cause of mild to moderate visual impairment.1 History of the disease2,3,4,5,6 1866 – Von graefe – first described the disease as recurrent serous retinitis. 1916 – Fuch’s work on the disease was appreciated. 1927 – Horniker – named disease as “Central Angiospastic Retinitis” 1930 – Walsh & Sloane – “idiopathic flat detachment of macula” 1930 – Gifford and Marquardt - Theory on Angioneurotic diathesis. 1953 – Klien – theory on autonomic nervous system dysfunction. 1950’s – Bennett & Maumenee – spectrum of macular disciform degeneration. 1955 – Bennett – “central serous retinopathy” 1960’s – Maumenee and Gass – FA appearance of CSC. 1967 – Gass – “central serous choroidopathy” Definition Active CS
