Choroidal rupture. A histopathologic study of 47 cases

Area of Science:

• Ophthalmology
• Pathology
• Trauma research

Background:

• Choroidal ruptures are a known consequence of ocular trauma.
• Understanding the healing process is crucial for managing visual prognosis.

Purpose of the Study:

• To characterize the histopathological features of choroidal ruptures.
• To describe the timeline and cellular mechanisms of choroidal rupture healing.

Main Methods:

• Examination of 47 surgical or autopsy ocular specimens.
• Specimens were collected from hours to 25 years post-trauma.
• Histopathological analysis of choroidal rupture sites.

Main Results:

• 39 indirect and 10 direct choroidal ruptures identified.
• Healing involves fibrovascular proliferation from the choroid.
• Formation of dense fibrous scar with retinal pigment epithelium hyperplasia.

Conclusions:

• Choroidal rupture healing is a consistent process.
• The process culminates in scar formation within approximately 3 weeks.
• Histopathology confirms the evolution of injury to scar tissue.
