Bilateral Coats' disease with unusual presentation--a case report

Area of Science:

• Ophthalmology
• Pediatric Ophthalmology
• Medical Imaging

Background:

• Coats' disease involves retinal telangiectasia, exudation, and detachment.
• It can mimic other serious ocular conditions, necessitating accurate diagnosis.

Observation:

• A 2-year-old boy presented with Coats' disease and neovascular glaucoma.
• Initial clinical and imaging diagnostics (ultrasonography, CT scan) could not rule out retinoblastoma.
• The right eye was enucleated, confirming Coats' disease histopathologically.

Findings:

• The patient later developed Coats' disease in his remaining left eye.
• This highlights the potential for varied presentations and bilateral involvement in Coats' disease.
• Late recurrence or progression of Coats' disease is possible, even years after initial diagnosis.

Implications:

• Accurate and timely diagnosis of Coats' disease is crucial, especially in differentiating it from retinoblastoma.
• Bilateral Coats' disease requires long-term monitoring and management.
• This case underscores the importance of considering Coats' disease in pediatric patients with retinal abnormalities.
