The choroid is detached from the sclera by exudates, blood effusions, or
blows with blunt articles. The lesion is especially common in recurrent
ophthalmia, choroiditis, and cyclitis. The ophthalmoscope will show the
detached portion as a rounded elevation on the otherwise smooth concave
surface, with normal or diminished intraocular tension. A _tumor_ of the
choroid is usually associated with increase of tension. After
inflammation has been subdued these cases may be left to rest and time,
and will often recover through absorption of the exudate. =Rupture of
the choroid= from violence is to be similarly dealt with.
