Retinal detachment occurs when the retina separates from its underlying supporting tissue, potentially leading to permanent vision loss without timely treatment. Symptoms may include sudden flashes, new floaters or a curtain-like shadow across vision. Surgery may involve vitrectomy or other retinal techniques depending on the type and extent of detachment.
Pars plana vitrectomy is a microsurgical procedure used to treat selected diseases affecting the vitreous and retina. The surgeon removes vitreous gel using specialised instruments introduced through small openings in the eye. It may be indicated for retinal detachment, vitreous haemorrhage, macular holes and other complex retinal conditions.
Diabetic retinopathy develops when diabetes damages small blood vessels within the retina. Early stages may not cause noticeable symptoms, making retinal screening important. Depending on disease severity, treatment can include blood glucose management, retinal injections, laser photocoagulation or vitrectomy for certain complications.
Retinopathy of prematurity is an eye condition affecting some premature infants because of abnormal retinal blood vessel development. Screening identifies infants who need monitoring or intervention. Treatment may include laser therapy, intravitreal medication or surgery in selected cases. Timely assessment is essential to reduce the risk of significant visual impairment.
Paediatric retinal disorders include congenital, developmental and acquired conditions affecting the retina in children. Assessment requires age-appropriate eye examination and specialised imaging when needed. Treatment depends on the disorder and may involve observation, medicines, laser intervention or retinal surgery, with attention to ongoing visual development.
A macular hole is an opening in the central retina that can cause blurred or distorted central vision. Selected patients may benefit from vitrectomy with removal of tractional membranes and placement of an internal gas bubble. Surgical suitability and expected recovery depend on hole characteristics and the duration of symptoms.
An epiretinal membrane is a thin layer of tissue that develops over the retinal surface and may distort central vision. Some cases require monitoring, while significant visual symptoms may lead to consideration of vitrectomy and membrane peeling. Treatment decisions depend on symptoms, retinal imaging and overall eye health.
Vitreous haemorrhage occurs when blood enters the gel-like substance filling the eye. It may result from diabetic retinopathy, retinal tears or other vascular conditions. Symptoms often include sudden floaters or reduced vision. Management involves identifying the cause and may include observation, laser treatment or vitrectomy.
Age-related macular degeneration affects the central retina and may reduce the ability to read, recognise faces or see fine detail. Assessment includes retinal examination and imaging. Management depends on whether the condition is dry or neovascular and may include monitoring, nutritional recommendations for eligible patients or intravitreal injections.
Intravitreal injections deliver medication directly into the vitreous cavity of the eye. They are commonly used for certain retinal conditions, including neovascular macular degeneration, diabetic macular oedema and retinal vein occlusion complications. The medicine and treatment schedule depend on the diagnosis and response to therapy.
Retinal laser photocoagulation uses focused laser energy to treat selected abnormalities in the retina. It may be used for retinal tears or certain complications of diabetic retinopathy and other vascular disorders. Treatment planning considers retinal imaging, location of the abnormality and the risk to surrounding retinal tissue.
Retinal vein occlusion occurs when a vein draining the retina becomes blocked, potentially causing swelling and reduced vision. Diagnosis involves retinal examination and imaging. Management focuses on assessing associated medical risks and treating complications such as macular oedema or abnormal retinal blood vessel growth.
Endophthalmitis is a serious inflammation, often caused by infection, affecting internal eye structures. Symptoms may include severe eye pain, redness and rapid vision deterioration. It requires urgent ophthalmic evaluation. Treatment may involve intravitreal antimicrobial medication and vitrectomy in selected cases, depending on severity and clinical findings.
Fluorescein angiography is an imaging test used to study blood circulation within the retina. A fluorescent dye is administered, and a specialised camera records its passage through retinal blood vessels. The test can help evaluate diabetic retinopathy, retinal vascular disorders and certain macular diseases.
Ocular B-scan ultrasonography uses sound waves to create images of structures inside the eye. It is particularly useful when cataracts, vitreous haemorrhage or other conditions prevent a clear view of the retina. The investigation can help identify retinal detachment and other abnormalities requiring specialist assessment.
Optical coherence tomography is a non-invasive imaging technique that produces detailed cross-sectional images of retinal layers. It helps evaluate macular swelling, macular holes, epiretinal membranes and other retinal disorders. Results support diagnosis, treatment planning and monitoring of retinal changes over time.
