Massive coats disease-like tumor after retinal detachment

Area of Science:

• Ophthalmology
• Retinal Surgery
• Vascular Tumors

Background:

• Rhegmatogenous retinal detachment (RRD) requires surgical repair, often involving scleral buckling.
• Long-term complications of RRD surgery are not fully understood.
• Coats disease is characterized by retinal telangiectasias and exudation.

Purpose of the Study:

• To report two cases of Coats disease-like tumor reaction occurring years after RRD surgery.
• To investigate potential causes and clinical features of this late complication.

Main Methods:

• Retrospective case review of two patients.
• Detailed clinical history, surgical records, and histopathological analysis.

Main Results:

• Two highly myopic patients developed retinal angiomatous tumors years post-RRD surgery.
• Tumors were associated with telangiectatic vessels and lipid exudates, resembling Coats disease.
• Histology showed vascular lacunae, inflammatory cells, and thickened capillary basement membranes.

Conclusions:

• Secondary Coats disease-like tumor reaction is a potential late complication after RRD surgery.
• Chronic ischemia and inflammation from scleral buckling elements may trigger this reaction in myopic eyes.
