[Anterior ischemic optic neuropathies]

The article presents a study on 82 patients hospitalized in the Clinic of Ophthalmology of Cluj-Napoca, during 1993-1999, with anterior ischaemic optic neuropathy (AION). There are presented the clinical and functional aspects of AION, especially the importance of static perimetry (PS) for the diagnosis, and her superiority, compared with the dynamic perimetry, in the monitoring of the patients with chronic nerve head ischaemia. After treatment, 32.9% of the cases have a favorable evolution, but PS reveals sequela visual field defects at all eyes which suffered AION. Long-term monitoring of the patients reveals unfavorable evolution at mare than 85% of cases, because of the chronic residual ischaemia, characterised by decreasing of visual capacity in PS. According with this findings, static perimetry has a important role in the diagnosis of AION, in revealing of the sequela defects and in the monitoring of the patients.
