Progression of age related maculopathy in phakic versus pseudophakic eyes.

Age-related maculopathy (ARM) is one of the leading causes of central visual acuity loss in older western population. Many factors are responsible for the fast development of ARM. One of this is significant increases of optical radiations through artificial lens after removal of the catarctous lens. The aim of this study was to compare progression of ARM in phakic and pseudophakic patients and to calculate the possibility ofpseudophakia as a risk factor for faster progression of ARM. Medical records of 76 patients, older than 60 years (32 male and 44 female) with early forms of ARM were randomly evaluated. They had undergone cataract removal by phacoemulsification with intraocular lens implantation from January 2002 to December 2006 at the Department of Ophthalmology, Rijeka University Hospital, Croatia. Patients were examined two weeks after the surgery and followed up for two years. The control group consisted of 48 patients (21 males and 27 females) with also early forms of ARM, older than 60 years, examined at the Policlinic Department from January 2006 to December 2006 and followed up at least for two years without any cataract surgery. Comparing progression of ARM in these two groups, a total of 19 patients (25%) in pseudophakic group showed progression to late forms of ARM, but only 6 patients (12.5 %) in the control group developed these aggressive ARM forms. More aggressive forms of ARM in pseudophakic group indicate that pseudophakia should be considered as a risk factor for development of ARM.
