When to seek emergency assessment
New flashes or a sudden increase in floaters need urgent retinal examination. A curtain, shadow, missing side vision or sudden reduction in vision may indicate a detachment and needs emergency assessment. Retinal tears and detachments can be painless.
A tear can lead to a detachment
A tear is a break in the light-sensitive lining at the back of the eye. Fluid can pass through the tear and lift the retina away from its normal position. Symptoms can resemble an uncomplicated posterior vitreous detachment (PVD).
A meticulous examination matters
Mr Rabie examines the retina through a dilated pupil, including its far edges. Special lenses and sometimes gentle pressure on the outside of the eye help show the peripheral retina. OCT or ultrasound may help assess the extent of the problem.
Why timing matters
A confirmed retinal detachment needs treatment as soon as clinically appropriate. Whether the macula is attached, where the detachment is and how it is changing guide the timing. Mr Rabie will prioritise repair according to these findings and discuss the quickest clinically appropriate route to treatment.
Treatment and recovery
Some tears can be sealed with laser or freezing treatment. A detachment often needs surgery, such as vitrectomy or a scleral buckle, sometimes with gas or oil. Mr Rabie will discuss the aim of surgery and the likely visual recovery. The Pars plana vitrectomy PDF explains the operation and gas precautions.
