Workup

Laboratory Studies

The diagnosis of a TRD is made clinically. Further laboratory workup is unnecessary.

Imaging Studies

In eyes with vitreous hemorrhage, a B-scan ultrasound is a useful adjunct to evaluate the presence or absence of retinal detachment.

Histologic Findings

The same findings as those found in RRD (see Retinal Detachment, Rhegmatogenous), that is, photoreceptor outer segment loss in the acute cases. Following successful retinal reattachment, regeneration of the outer segments may occur. In chronic detachments, atrophy of the entire photoreceptor layer, cystic degeneration, macrocyst formation, demarcation lines, and even rubeosis iridis may be seen.

In addition, TRDs have periretinal proliferation. Light and electron microscopy have revealed the composition of the periretinal membranes. These are composed of RPE cells, astrocytes, fibrocytes, monocytes, and collagen fibrils.
