Abstract Details

Purpose:

Οur purpose is to present an interesting case of progressive visual function deterioration at a young highly myopic patient.

Setting:

Department of Ophthalmology, ‘’Hippokrateion’’ General Hospital of Thessaloniki, Thessaloniki, Greece.

Methods:

30 years old short sighted patient complained of bilateral blur of vision, especially at his right eye from about a month ago. His visual acuity was at the right eye(RE): 1/10 (-9,00sph, -2,50cylx180) and at the left eye(LE): 6/10(-8,50sph). A deteriorating, remittent, horizontal, jerky nystagmus was also found. The rest of the clinical examination was normal. We proceeded the workup with visual fields testing, macula and optic nerve OCT, MRI, neurological examination and electrodiagnostic testing(EDT)/electroretinography (ERG).

Results:

Visual fields, OCT, MRI, neurological examination were within normal limits. EDT/ERG showed recording asymmetry between the two eyes at the scotopic and photopic ERG and reduction in b-wave amplitude especially at the RE which was attributed to changes due to high myopia.

Conclusions:

Even though the actual mechanism is still unclear, optical, electrical, and retinal factors have been suggested. In literature, it is known that ERG changes may precede fundus and OCT changes in highly myopic young adults. These are mainly met in adults and rarely to children with high myopia and are related to increased possibility of macular degeneration. Finally, we should not omit from the differential diagnosis genetic causes that can cause gradual vision deterioration, as gene testing can give us helpful answers. FINANCIAL DISCLOUSRE: NONE
