Macular degeneration. Is there a nutritional component?

Although the disciform type of senile macular degeneration (SMD) was first recognized in the last century, 1 it was considered an uncommon condition; as recently as 1939, only 130 cases were reported in the literature. 2 The clinical evolution of SMD was not understood, and concepts were based on morphologic findings of advanced cases. Hemorrhage in the subretinal space was recognized as an important feature, 3 but neovascularization was thought to be secondary to fibrovascular organization of the blood. 4 Although the term senile macular degeneration has been used since Haab 5 in 1885 first described the clinical entity of pigmentary and atrophic changes in the macula, the close relationship between macular drusen 6 and disciform macular degeneration was generally overlooked. 7 See also p 192. With the development of fluorescein fundus angiography, the evolution and morphology of SMD can be demonstrated during the lifetime of the patient. Utilizing this
