What is a macular hole?
A full-thickness macular hole is an opening in the centre of the retina. It can blur or distort central vision and make reading or recognising faces harder. Mr Rabie examines the eye and uses an OCT scan to measure the hole and look for traction.
Why timing matters
A macular hole usually does not require emergency surgery, but a treatment plan should be made promptly. A hole left untreated can enlarge and central vision can deteriorate. Smaller, more recent holes generally have a better chance of closure and useful visual recovery.
Delicate surgery on the macula
During pars plana vitrectomy, Mr Rabie releases the pull of the vitreous and carefully peels a very thin layer on the retinal surface called the inner limiting membrane. A temporary gas bubble holds against the macula to help the edges of the hole come together.
Gas and positioning
Gas duration depends on the type. A commonly used medium-acting gas clears in around six weeks. Follow the instructions about face-down positioning and sleeping if prescribed. Do not fly or travel to high altitude while gas remains and tell healthcare professionals so they can avoid nitrous oxide. See the Pars plana vitrectomy PDF for more on gas and recovery.
How much vision may recover?
Surgery closes most macular holes, especially smaller and more recent ones. Closure and visual improvement are different outcomes. Reading and distortion can improve gradually over several months, but some blur or distortion may remain. Mr Rabie will explain what the scan suggests for your eye.
