[Visual evoked potentials in diagnosis and monitoring of optic neuropathy in the course of thyroid ophthalmopathy].

Purpose: To evaluate the usefulness of pattern visual evoked potentials (PVEP) in early diagnosis and monitoring of dysthyroid optic neuropathy (DON).

Material And Methods: We recorded PVEP (UTAS E--1000) in 74 patients with thyroid ophthalmopathy (TO) including 12 patients with clinically evident DON--group I, 13 patients with subclinical DON (prolongation of latency of P100 wave in PVEP)--group II, and 49 patients without clinical or electrophysiological signs of DON--group III. Thirty six healthy subjects served as controls.

[The influence of treatment of progressive edematous infiltrative ophthalmopathy on intraocular pressure].

Purpose: To evaluate the influence of systemic steroid therapy and retrobulbar irradiation on intraocular pressure (IOP) in patients with infiltrative--oedematous Graves' ophthalmopathy.

Material And Methods: We examined 76 patients divided into 3 groups: I--treated by irradiation only (15 patients), II--treated by irradiation and oral prednisone therapy (26 patients), III--treated by irradiation and intravenous methylprednisolone pulse therapy (35 cases). All patients underwent full ophthalmological examination (including IOP measurement, perimetry and gonioscopy) before, during, immediately after and 2-20 months after treatment.
