What causes Cecocentral scotoma?
Conclusions: In spite of a selective referral bias, retinal disease was the most common pathophysiology causing central and cecocentral scotomas. The addition of OCT and anatomic studies helped to distinguish these, although even when the macula looked normal, functional studies such as multifocal ERG may be necessary.
What causes visual scotoma?
Common causes of scotomata include demyelinating disease such as multiple sclerosis (retrobulbar neuritis), damage to nerve fiber layer in the retina (seen as cotton wool spots) due to hypertension, toxic substances such as methyl alcohol, ethambutol and quinine, nutritional deficiencies, vascular blockages either in …
