Comparison of visual evoked potentials, automated perimetry and frequency-doubling perimetry in early detection of glaucomatous visual field loss.

The present study compares frequency-doubling perimetry (FDP), automated perimetry (AP) and visual evoked potentials (VEP) for their ability to diagnose early glaucoma. In present study 224 patients of Clinic for Eye Diseases, Clinical Hospital "Sestre Milosrdnice" that had diagnosis of open angle glaucoma and glaucomatous visual field loss proven by automated static perimetry on only one eye were performing all three tests. Visual evoked potentials, automated perimetry and frequency-doubling perimetry were performed four times in each patient with six months period in between testing.

[Ocular changes in hemorrhagic fever with renal syndrome].

Hemorrhagic fever with renal syndrome (HFRS) is a rodent-originating zoonotic disease caused by Puumala and Dobrava viruses, which belong to the genus Hantavirus. The most prominent ocular change in HFRS is transient myopia, which lasts for up to one week and is due to a forward movement of the ocular anterior diaphragm and thickening of the lens. Other ophthalmic manifestations of HFRS are eyelid edema, conjunctival injection with or without hemorrhages, chemosis, anterior uveitis, retinal edema with or without hemorrhages, and photophobia.
