Coats syndrome

Coats syndrome is a rare eye disorder marked by abnormal retinal blood vessels that leak fluid, causing vision loss, retinal detachment, and sometimes blindness, usually affecting one eye in children or young adults

Rare View

​Coats' disease is a rare, non-hereditary eye disorder characterized by abnormal development of the blood vessels in the retina, leading to fluid leakage and potential vision loss. It predominantly affects young males and typically presents unilaterally.

5 Facts you should know

FACT

1

Most people begin showing symptoms in childhood

FACT

2

Early signs and symptoms vary but may include vision loss, "crossed eyes" (strabismus), and a white mass in the pupil behind the lens of the eye (leukocoria)

FACT

3

Over time, Coats disease may also lead to retinal detachment, glaucoma, and clouding of the lens of the eye (cataracts)

FACT

4

In most cases, only one eye is affected

FACT

5

The irregular caliber of telangiectatic vessels, aneurysms, subretinal exudates, and lack of calcification on ultrasound differentiates it from retinoblastoma

Coats syndrome is also known as:

  • Retinal telangiectasis
  • Eye diseases
  • Nervous System Diseases
  • Leber miliary aneurysm
  • Hemorrhagic glaucoma
  • Congestive glaucoma
  • Thrombotic glaucoma
  • Rubeotic glaucoma

What’s your Rare IQ?

Coats Syndrome, a rare eye disorder, primarily affects the retina. What is a characteristic feature of Coats Syndrome?

 

Common signs & symptoms

Decreased vision, strabismus, leukocoria (advanced), visual field defects

Fundus: retinal telangiectasia (“light-bulb” aneurysms), hard exudates, subretinal fluid/exudative detachment

Key diagnostic step: exclude retinoblastoma (imaging + exam)

Current treatments

Mainstays: laser photocoagulation and/or cryotherapy to ablate telangiectatic vessels; approach depends on stage and detachment extent.

Adjuncts in selected cases: intravitreal steroids or anti-VEGF (pediatric safety considerations), vitreoretinal surgery for complex detachments

End-stage/painful blind eye or diagnostic uncertainty: enucleation may be considered
