What does retinal detachment mean?
The retina is the light-sensitive layer of tissue that lines the inside of the eye and sends visual messages through the optic nerve to the brain. When the retina detaches, it is lifted or pulled from its normal position. If not promptly treated, retinal detachment can cause permanent vision loss.
Who is at risk for retinal detachment?
A retinal detachment can occur at any age, but it is more common in people over 40 years. It affects men more than women.
A retinal detachment is also more likely to occur in people who
- Are extremely nearsighted(high myopes)
- Have had a retinal detachment in the other eye
- Have a family history of retinal detachment
- Following cataract surgery, there is a 1% to 2% chance of developing a retinal detachment.
- Have other eye diseases or disorders, such as retinoschisis, uveitis, degenerative myopia, or lattice degeneration
- Have had an eye injury
What are the alarming symptoms of retinal tear and detachment?
- Floaters which are little “cobwebs” or specks that float about in your field of vision
- Light flashes in the eye
- Sudden blurry vision
- An area of dark vision, like a curtain or a veil coming from above or below or from the sides.
Floaters are a common symptom in otherwise normal individuals. However if these are accompanied by persistent flashes, they could be symptoms of a retinal tear or detachment.
What are retinal holes / tears?
Holes are small circular defects in the retina. Tears are due to a flap of retina being pulled off as the vitreous shrinks.
What do you mean by laser and cryo therapy?
Laser therapy (Diathermy):
Laser is a beam of light that is converted to heat when it hits the retina. This welds the retina to the underlying choroid.
Cryotherapy refers to a cold probe that freezes the tissue around the tear causing the retina and choroid to stick together.
What is Vitrectomy?
The vitreous is removed, therefore the name “Vitrectomy”. The lack of vitreous does not affect the functioning of the eye.
Narayana Nethralaya has the latest and the most sophisticated surgical equipments. Micro incision and sutureless (23/25 gauge) vitrectomy(MIVS) is performed using the CONSTELLATION® machine.
The advantages of this surgery is the absence of stitches in the eye; hence the post-operative recovery is faster.
The surgeries performed in our department are as follows
- Scleral Buckling
- Vitrectomy for retinal detachments, epiretinal membrane, macular hole,vitreomacular traction, vitreous hemorrhage, parasitic cysts, dislocated nucleus, dislocated intra ocular lens
- Vitrectomy for diabetic retinal detachment
- Scleral fixated IOLs
- Surgery for trauma-related conditions
- Subretinal surgery
- Surgery for intra ocular infections
