Epiretinal Membrane
Epiretinal membranes(ERM) are acquired formation of semi-transparent cellular sheets on the macular surface, which are formed due to varied etiologies. These membranes have contractile properties, often leading to mechanical distortion of macula. The proliferation of ERM on the inner retinal surface along the internal limiting membrane was first described by Iwanoff in 1865 1. In 1971, Roth and Foos reported that in a series of autopsied eyes, ERM were present in 2 percent of patients aged 50 yr and in more than 20 percent of patients by age 75 yr2. Pearlstone reported an incidence of 6.4 percent in 1000 consecutive routine eye examinations in patients older than 50 yr, with 20 percent being bilateral 3,4. Other authors report bilateral involvement in 10 to 20% of cases5,6,7.The Los Angeles Latino Eye Study (LALES) found that of the participants with ERM, 19.9% had bilateral ERMs. The prevalence of ERM increased from 10.1% in persons 40 to 49 years of age to 35.7% in those aged 70 to 7
