| A
rhegmatogenous retinal detachment may form due to a hole or a tear in the
retina secondary to traction or degeneration.
This allows fluid into the space between the retina and the RPE and
may cause a retinal detachment. Fundus
examination often reveals a small hole or a horseshoe type tear in the
retina (#22077) with an elevated, translucent, and irregular detachment of
the retina (#22078). Gross
pathologic examination of a long-standing retinal detachment often reveals
the classic funnel shape of the detachment(#22080).
The retina remains attached in the are of the optic nerve as well
as the ora serrata but is detached in the other areas(#22081).
Histopathologically, in the early stages a retinal detachment will
show degeneration of the outer retinal layers and photoreceptors with
subretinal exudate present. Long-standing
detachments can show disruption and atrophy of normal retinal architecture
with extensive gliosis or proliferative vitreoretinopathy.
