Consult an ophthalmologist immediately if you experience sudden flashes of light, floaters, or a curtain-like vision loss – these are key symptoms.
Rhegmatogenous retinal detachment (RRD) occurs when the retina separates from the underlying choroid due to a retinal tear or hole. This allows vitreous fluid to seep beneath the retina, lifting it away from its support structure. Understanding the causes, diagnosis, and treatment is crucial for preserving vision.
- Causes: RRD frequently develops following vitreous detachment, a natural aging process where the vitreous gel pulls away from the retina. Other contributing factors include high myopia (nearsightedness), eye trauma, previous eye surgery, and certain eye diseases. Diabetic retinopathy can also contribute. Diagnosis: A dilated eye exam is the primary diagnostic tool. Your doctor will use an ophthalmoscope to visualize the retina and look for tears, holes, or retinal detachment. Optical coherence tomography (OCT) provides high-resolution images for detailed assessment.
Treatment aims to reattach the retina and prevent further vision loss. Surgical intervention is typically necessary.
Pneumatic Retinopexy: A gas bubble is injected into the eye to push the retina back against the choroid. Laser treatment or cryotherapy seals the retinal tear. You’ll need to maintain specific head positions post-surgery. Scleral Buckle: A silicone band is placed around the outside of the eye to indent the sclera and push the retina back into place. This is often combined with laser or cryotherapy. Vitrectomy: This involves removing the vitreous gel and using a fluid to replace it. Retinal tears are then sealed with laser or cryotherapy. This is a more involved procedure, often used for complex detachments.
Post-operative care is vital. This includes regular follow-up appointments, adherence to prescribed medications, and cautious activity levels to promote healing and minimize the risk of re-detachment. Early diagnosis and prompt treatment significantly improve the chances of successful reattachment and vision preservation. Remember, timely intervention is key.
