Summary
Late complications of hydrogel retinal explants can cause large orbital masses. These masses, presenting decades after surgery, are expanded explant material causing functional impairment.
Area of Science:
- Ophthalmology
- Ophthalmic Pathology
- Retinal Surgery Complications
Background:
- Hydrogel retinal explants were utilized in the 1980s for retinal detachment repair.
- Late complications can arise decades after the initial surgery.
Purpose of the Study:
- To characterize orbital masses as a late complication of hydrogel retinal explants.
- To describe the clinical and histopathological features of these masses.
Main Methods:
- Retrospective review of patients with orbital masses.
- Patients presented decades after retinal surgery with hydrogel explants.
Main Results:
- Two cases presented with huge orbital masses 25 and 28 years post-surgery.
- Masses were identified as expanded hydrogel explants with fibrous capsules.
- Histopathology revealed mild inflammation and calcification.
Conclusions:
- Expansile hydrogel explants can cause delayed, tumor-like parabulbar masses.
- These masses lead to orbital dysfunction and structural distortion.
- Surgical removal resulted in functional improvement.
