Retinal Detachment: Torn or Detached Retina Diagnosis
Your ophthalmologist can diagnose retinal tear or retinal detachment during an eye examination where he or she dilates (widens) the pupils of your eyes. An ultrasound of the eye may also be performed to get additional detail of the retina.
Only after careful examination can your ophthalmologist tell whether a retinal tear or early retinal detachment is present.
Some retinal detachments are found during a routine eye examination. That is why it is so important to have regular eye exams.
