Phthisis bulbi, also known as end-stage eye, is an atrophic scarred and disorganised globe that may result from a variety of severe ocular insults.
The globe is reduced in size (usually <20 mm) with a thickened/folded posterior sclera. Dystrophic calcification is common, and osseous metaplasia sometimes occurs, forming what is called "intraocular bone".
Causes of this end-stage damage include:
- trauma (causes ciliochoroidal effusion and cyclitic membrane)
- other inflammatory processes
- chronic retinal detachment
- persistent hyperplastic primary vitreous
Treatment and prognosis
The globe is non-functioning, thus the patient is blind in that eye. Enucleation +/- prosthesis insertion is performed if there is associated chronic pain or for cosmetic reasons.
The differential includes other causes of calcification of the globe.
