Popis: Toksoplazmotski retinokoroiditis bolest je oka uzrokovana parazitom Toxoplasma gondii. U ljudskome oku infekcija toksoplazmom najčešće se očituje kao fokalni nekrotizirajući retinitis, uz sekundarni razvoj koroiditisa koji zahvaća unutarnje slojeve mrežnice, a očituje se kao fokalna žuto-bijela lezija s okolnim edemom mrežnice i upalnim infiltratom staklovine. Te promjene, uslijed reakcije preosjetljivosti na antigen, prate različiti oblici prednjega ili stražnjega uveitisa. Lezija obično cijeli unutar razdoblja od jednoga do četiri mjeseca uz formiranje oštro ograničenoga atrofičnog ožiljka pigmentiranih rubova. Liječenje u većini slučajeva nije potrebno. Ako je potrebno, klasično liječenje sastoji se od peroralne primjene pirimetamina, sulfadiazina i folinične kiseline. U liječenju toksoplazmotskoga retinokoroiditisa makularne lokalizacije dodatno se primjenjuju kortikosteroidi s ciljem smanjenja upalne reakcije i ubrzanja oporavka vida, što je prikazano u ovome slučaju.
Toxoplasmotic retinochoroiditis is a disease of the eye caused by the Toxoplasma gondii parasite. In the human eye, toxoplasma infection mostly presents itself as a focal necrotizing retinitis with secondary choroiditis, involving the inner retinal layers and appearing as a focal yellow-white lesion with surrounding retinal edema and focal vitreous infiltrate. This is followed by varying degrees of posterior and anterior uveitis due to hypersensitivity reaction of antigens. The lesion usually heals within one to four months and is replaced with a sharply demarcated atrophic scar with pigmented borders. In most cases there is no need for treatment. When treatment is necessary, classic therapy consists of oral administration of pyrimethamine, sulfadiazine, and folinic acid. In treatment of ocular toxoplasmotic retinochoroiditis that affects the macular area, additional administration of corticosteroids to diminish inflammatory reaction and hasten visual acuity recovery has its place, as it is showed in this case.
