The second case arose because of the inadequateinformation about the importance of screening tests.Keywords: Chloroquine, Hydroxychloroquine, RetinaltoxicityÖZETİki antimalarial ilaç kullanımına bağlı retinopati olgususunduk ve antimalarial tedavisinde tarama yöntemlerinideğerlendirdik.Retina bölümümüzde takip edilen iki olgunun klinikkayıtları, fundus fotoğrafları, görme alanı, flöresananjiografileri incelendi.İlk olguda testler yapılmış olduğu halde sonuçlarınınyanlış yorumlanması, ikinci olguda ise hastaya taramatestlerinin öneminin yeterince anlatılmamış olmasısebep olarak görüldü.Anahtar Kelimeler: Klorokin, Hidroksiklorokin,Retinal toksisiteINTRODUCTIONThe diagnosis of advanced chloroquineand hydroxychloroquine retinopathy is based on thecombined presence of parafoveal pigment epithelialatrophy as seen on fundus biomicroscopy, andacquired paracentral scotoma on threshold visualfield testing using the 10-2 program with white testlight on a Humphrey perimeter 1 . Although the effectsof long term usage of antimalarials are well known, itis still debatable what type and what frequency ofscreening should be performed to recognize toxicityas early as possible.Here we present two cases of antimalarialretinal toxicity which resulted with severe visualimpairment. Old and new screening methods to ruleout possible ocular toxicity, the dose monitoringguidelines and the follow up strategy aresubsequently discussed.Both cases were screened for color visiondefects with 25 plates of Ischiara test. The visionfield tests were performed with The HumphreyVisual Field Analyzer (HFA; Carl Zeiss Meditec,Dublin, CA) in our department. All previous visionfield tests were also performed with The HumphreyVisual Field Analyzer. For each patient, fundusflourescein angiography and fundus photographywere performed to diagnose maculopathy.Başvuru tarihi / Submitted: 06.02.2010 Kabul tarihi / Accepted: 06.09.2010Correspondence to: Özlem Yenice, M.D. <strong>Marmara</strong> Üniversites Tıp Fakültesi, Göz Hastalıkları Anabilim Dalı,İstanbul, Türkiye. e-mail: yeniceozlem@yahoo.com68<strong>Marmara</strong> <strong>Medical</strong> <strong>Journal</strong> 2011; 24 (1):68-72
