| Table 26.1 Causes of chorioretinal folds | ||
|---|---|---|
| Category | Examples | |
| Orbital space-occupying pathology | Orbital tumors and thyroid eye disease | |
| Choroidal tumors | Melanoma of the choroid and metastatic carcinomas | |
| Optic disc swelling | Expansion of the optic nerve at its entrance into the eye,causing compression of the surrounding choroid | |
| Ocular hypotony | Low intraocular pressure, e.g. post-surgical, trauma | |
| Hypermetropia | A single underlying pathology (e.g. inflammation during infancy) may be responsible for both hypermetropia and chorioretinal folds |
|
| Previous scleral surgery | Such as scleral buckling procedures for retinal detachment |
|
| Posterior uveitis Idiopathic |
An incidental finding in an otherwise normal eye | |
| Other causes | Intraocular tumors, choroidal neovascular membranes and orbital cellulitis |

Surgery Intraocular or orbital surgery may be indicated depending on the underlying cause.
Advice Although treatment of the underlying condition sometimes results in resolution of the folds, they quite often persist indefinitely.
