Panretinal photocoagulation is a laser treatment that places many tiny burns across the peripheral retina to reduce abnormal new blood vessels in conditions such as proliferative diabetic retinopathy.
Why PRP laser is important
When parts of the retina do not receive enough oxygen, they release signals that encourage fragile new vessels to grow. These can bleed, scar, and pull on the retina, threatening sight.
- PRP reduces the retina’s demand for oxygen and shrinks new vessels
- Helps prevent severe bleeding or tractional detachment
- Often done in several sessions to balance effectiveness and comfort
- May be combined with intravitreal injections for best control
Experience during and after treatment
The procedure is usually carried out with numbing drops while you sit at a laser machine. You may see bright flashes and feel brief, sharp pricks or dull ache; extra anaesthetic can be given if needed.
- Side effects can include reduced night or peripheral vision
- Temporary blurring and mild soreness are common for a day or two
- Good diabetes and blood pressure control remain vital long term
- Regular follow up checks for any new vessel growth or complications
