| Summary: |
Purpose: The aim of
this study is to present rare retinal disease of unknown
origin.
Material and methods: 27-years-old man was
diagnosed because of poor vision in the left eye, which
lasted 4-5 weeks. Following examinations were performed:
Visual acuity, contrast sensitivity, color perception,
visual field, fluorescein angiography (AF), visual
evoked potentials (VEP), full-field flash
electroretinography (flash ERG), focal – foveal
electroretinography (focal ERG), multifocal
electroretinography (multifocal ERG). Follow-up 1.5 year.
Results: Visual acuity of right eye was 1.25
(-0.1 log MAR) and left eye 1.0 (0.0 log MAR). In left
eye between optic disc and macula irregular lesion with
dots of retinal pigment epithelium atrophy and little
edema was seen. AF revealed small „window” defects. In
visual field of the left eye paracentral relative
scotoma occurred and in stereokampimetry central
relative scotoma was found about 5 degrees from the
fixation point. In VEP latency of P100 was delayed and
amplitude was reduced in both eyes. In flash as well as
focal ERG small reduction of cone function and delayed
implicit time of b-wave were found in left eye. In
general examination no focal inflammation and no
abnormalities in laboratory tests were found. The
patient was treated with steroids for 3 weeks. After ten
days of general steroid treatment visual acuity improved
to 1.25 and subjective improvement of vision occurred.
Control examination after 1.5 year revealed no patient's
complains, visual acuity 1.25, no change in visual field,
VEP improvement. In left eye flat irregular area with
pigment epithelium atrophy was seen.
Conclusions: Acute macular neuroretinopathy may
be diagnosed after detail examination. Prognosis is
generally good, recovery is slow, but despite of local
retinal atrophy subjective complains disappear
completely. |
