Aside the manifest small-angle deviation ("tropia"), subjects with MFS often also have a large-angle latent deviation (phoria). Their stereoacuity is often in the range of 3000 to 70 arcsecond, and a small central suppression scotoma of 2 to 5 deg.[2] A rare condition, MFS is estimated to affect only 1% of the general population. There are three distinguishable forms of this condition: primary constant, primary decompensating, and consecutive MFS. It is believed that primary MFS is a result of a primary sensorial defect, predisposing to anomalous retinal correspondence.[3] Secondary MFS is a frequent outcome of surgical treatment of congenital esotropia.[4] A study of 1981 showed MFS to result in the vast majority of cases if surgical alignment is reached before the age of 24 months and only in a minority of cases if it is reached later.[5] MFS was first described by Marshall Parks.[2] References1. ^{{cite web |url=http://emedicine.medscape.com/article/1199953-overview |title=Monofixation Syndrome: eMedicine Ophthalmology |format= |work= |accessdate=}} 2. ^1 {{cite book|author1=Kenneth Weston Wright|author2=Peter H.
