| Abstract | BACKGROUND. Pupillometry is non-invasive examination used to measure width of the pupil. Pupillography not only measures the diameter, but also detects and records responses of the pupil, among others the pupil light reflex (PLR). Pupillograph is an instrument (device) that objectively and quantitatively evaluates PLR using a computer. This investigation is relatively new and can be helpful in fast diagnostics of retinal or optic nerve disorders. Optic neuritis (ON) is an acute inflammation of optic nerve. Signal transmission is disturbed and the consequence is an abnormal PLR. Color vision, visual acuity and visual field are also affected. Visual abnormalities usually spontaneously recover but illness often recurrs. AIM. Pupillograph CIP (Compact Integrated Pupillograph) has not been used in Slovenia yet. The aim of the present study was to provide normatives for PLR and interocular differences between right and left eye's PLR in normal subjects. We were also interested in PLR changes in patients with ON and in differences between aff'ected and nonaffected eye. We also wanted to examine a correlation between results of pupillometry and results of other examinatioms (spatial vision, colour vision and visual aquity) in acute phase of an illnes and after one month. HYPOTHESIS. 1. In healthy subjects we do not expect any interocular differences of PLR. 2. We think that PLR is going to be changed (decreased) in patients with ON in acute phase. Latency will be longer and amplitude decreased in affected eye. 3. After one month PLR of affected eye is going to be changed in correlation with course of illness. In case of improvement, latency will be shorter and amplitude increased. 4. There will be a correlation between pupillography as an objective examination and psychophysical examinations: visal acuity, perimetry and colour vision. (Abstract truncated at 2000 characters). | |
