What happens at assessment
Assessment starts with the diagnosis and the reason injections are being considered, such as wet AMD, diabetic macular oedema, or macular oedema from retinal vein occlusion.
The visit typically includes visual acuity measurement, retinal examination, OCT imaging, and comparison with previous findings where available. This establishes whether there is active fluid, swelling, bleeding, or structural change affecting the macula.
How OCT guides treatment decisions
OCT provides a cross-sectional view of the macula and shows whether fluid is present within or under the retina. It also helps document retinal thickness, structural change, and response to previous treatment.
OCT findings are interpreted together with vision and examination findings. This is important because symptoms alone do not always reflect the degree of retinal activity.
Conditions we assess and treat
OCT retinal imaging
OCT provides a detailed cross-sectional view of the retina and is central to modern retinal care. Imaging supports diagnosis, establishes a baseline, and allows precise comparison over time.
In injection care, OCT is used to document whether retinal fluid is improving, recurring, or stable, alongside visual acuity and clinical findings. This supports treatment planning and follow-up. More detail is available on the Technology & Diagnostics page.
The role of visual acuity
Visual acuity is measured because the aim of treatment is not only to improve an image on OCT, but to protect useful central vision. Vision results are interpreted alongside OCT findings and the patient's day-to-day visual function.
In some cases the OCT may improve before vision changes significantly; in others, vision may be limited by longer-standing retinal damage. This is why treatment response is assessed using both imaging and visual function.
What are intravitreal injections?
Intravitreal injections deliver medication inside the eye to treat conditions affecting the macula and retina. Planning is based on symptoms, examination findings, and OCT results.
Injections are used when there is retinal fluid, bleeding risk, or active disease that threatens central vision. The decision is individualised and guided by imaging and clinical response.
Anti-VEGF and other treatments
Anti-VEGF medications reduce abnormal blood vessel leakage and swelling in the retina. They are commonly used for wet AMD and other retinal vascular conditions.
In selected situations, other medications including steroid-based treatments may be considered. Retinal laser photocoagulation may also be recommended as part of a broader management plan.
What to expect on injection day
- The eye is numbed and cleaned carefully
- The injection is brief and typically well tolerated
- Post-treatment instructions are reviewed clearly
Injection treatment and follow-up are planned according to the diagnosis, OCT findings, visual function, and clinical response. The practice documents the clinical information needed for ongoing care.
Aftercare and safety
Mild irritation, tearing, light sensitivity, or a small red spot on the eye are normal and usually resolve quickly. Avoid rubbing the eye and swimming for a short period after treatment.
Intravitreal injections are common and generally safe when performed with sterile technique. Rare risks include infection inside the eye (endophthalmitis), retinal tear or detachment, bleeding, or significant inflammation.
