Follow-up and prognosis


Regular life-long follow-up by an ophthalmologist every 6 months should be offered to all individuals with Coats disease.


Stabilization of the disease course or clinical improvement can be achieved in approximately 75 % of the cases, using a carefully selected therapy. However, recurrence of the telangiectasia and retinal exudation after successful treatment is possible, as found in 7 % of cases after a mean of 10 years in a retrospective consecutive series of 150 patients. This stresses the importance of a long-term follow-up of the affected patients.
