In the second part of the paper we present ophthalmic complications of fungal infections in immunocompromised patients. Among about 200,000 known species of fungi, only approximately 200 are pathogenic for human. Many of them are not able to cause a disease in persons with normal immunity, but in immunocompromised patients they are the cause of severe, frequently lethal disorder. Most important agents are Candida albicans, Cryptococcus neoformans, Aspergillus fumigatus and Histoplasma capsulatum. Pneumocystis carnii, formerly considered to be a protozoan, currently is rated among fungi, and plays a very important role as a opportunistic pathogen in patients with AIDS. There are presented data about ocular involvement during fungal opportunistic infections--symptoms and clinical picture as well as methods of diagnosing and treatment.
