Retinal Detachment is a disorder of the Eye where the retina is pulled away from the tissue that supports it. Initially, but not always, the progression starts from a small tear and if not treated, can progressively worsen.
Without treatment, vision loss and blindness are possible.
This is considered a medical emergency!!!
What is the Retina?
This is a thin layer of tissue on the back wall of the eye. It is light sensitive. The eye itself focuses light – which is than transferred to the retina.
From the retina – the light is transformed into neural impulses that travel to the brain via the opitc nerve.
1.) Following Surgery especially after Cataract Surgery
2.) Traumatic injury
3.) Diabetic Retinopathy
4.) Malignant Hypertension
5.) Eclampsia during pregnancy
6.) Other causes
– Flashes of light
– Sudden increase in floaters
– Feeling of heaviness in eye
– A shadow in periphery of vision that progresses towards the central vision
– Visual loss
* – Pain is not always a symptom and is often not a symptom.
– Immediately eye evaluation is necessary.
– Use of fundus photography
– Use of Ophthalmography
– Freezing of the wall or area of retinal detachment – this helps prevent further tearing of the retinal.
2.) Laser Photocoagulation
– Use of laser is similar to freezing. Done at the wall or area of retinal detachment – this helps prevent further tearing of the retinal.
3.) Surgery to perform a Scleral Buckle
– A silicone band is placed on the sclera.
– This pushes the wall of the eye inward.
– Reduces the flow of fluid through the Vitreous
– This allows the retina to re-attach.
4.) Surgery to form Pneumatic Retinopexy
– A gas bubble is injected into eye
– Laser or Freezing is then used to the retinal hole.
– Head is tilted for up to several days to keep gas bubble in contact with the hole.
– Sealing of the hole will take place
– If hole is in the lower part of the eye – this option is not available.
– Increasingly used
– Vitreous gel is removed and filled with silicon oil.
***85% of cases will be successfully treated with x 1 operation
***15% will need more than one.
