Overview
Maintaining sharp vision is essential to daily life, work, and independence. When subtle visual distortions or sudden flashes occur, consulting a dedicated retina specialist provides clarity, accurate diagnosis, and specialised care tailored to your needs.

Senior Consultant Ophthalmologist & Retina Specialist
With extensive fellowship training and decades of clinical experience, Dr Bobby Cheng specialises in complex retinal diseases, vitreoretinal surgery, and comprehensive eye care at Cornerstone Eye & Retina Centre in Singapore.
Introduction
Clear vision supports your work, relationships, and independence. When something feels different about your eyes, finding prompt answers matters.
A retina specialist focuses on the delicate internal structures at the back of the eye, offering targeted care for conditions ranging from diabetic retinopathy to age related macular degeneration. Many patients overlook early symptoms, assuming mild blurriness is simply a result of aging or an outdated glasses prescription. Recognising when specialist assessment is needed can protect your sight and prevent long term complications.
What Does a Retina Specialist Treat?
The retina is a thin layer of light sensitive tissue lining the back of the eye. It converts light into signals sent to the brain, making it fundamental to everything you see.
Dr Bobby Cheng completed advanced fellowship training focused on the retina and vitreous body (the gel like substance filling the eye). Conditions commonly managed include:
- Age related macular degeneration (AMD)
- Diabetic retinopathy and diabetic macular oedema
- Retinal detachment and retinal tears
- Macular holes and epiretinal membranes
- Retinal vein occlusions
- Ocular inflammation and uveitis
Timely medical or surgical treatment helps preserve both central and peripheral vision, supporting long term quality of life.
Retina Specialist vs General Ophthalmologist
Understanding the difference in training helps patients choose the right care. A general ophthalmologist manages overall eye health, performs routine cataract surgery, and treats common surface conditions. A retina specialist undergoes additional years of subspecialty fellowship training dedicated to medical retinal disease and vitreoretinal surgery.
When Should You See a Retina Specialist?
Recognising the warning signs of retinal disease requires awareness. An assessment is recommended if you experience persistent visual disturbances that new glasses fail to correct. Symptoms warranting prompt evaluation include:
- Sudden floaters or flashes of light — May indicate a retinal tear or detachment.
- Straight lines appearing wavy or distorted — Known as metamorphopsia, a hallmark sign of macular disease.
- A dark shadow or curtain across your vision — May signal an advancing retinal detachment and requires same day assessment.
- Gradual or sudden loss of central vision — Difficulty reading, driving, or recognising faces can indicate macular involvement.
⚠️ Sudden vision loss or a curtain across your visual field is a medical emergency. Seek urgent assessment without delay.
What to Expect During Your Consultation
Your first visit involves a structured evaluation to identify the cause of your symptoms. The clinical team begins with preliminary measurements, including visual acuity testing and intraocular pressure checks. Dilating eye drops are then applied to widen the pupils, allowing Dr Bobby Cheng to examine the retina in detail using OCT and high magnification lenses.
Following the examination, Dr Bobby Cheng will discuss the findings and outline a management plan, whether that involves monitoring, laser therapy, intravitreal injections, or vitrectomy surgery. Insurance coverage and MediSave options are reviewed to ensure clarity around costs from the outset.
Treatment Pathways and Recovery
Modern retinal treatment offers effective options for preserving sight across a range of conditions.
- Intravitreal Injections — Anti VEGF medications such as Eylea, Vabysmo and Lucentis are delivered directly into the eye to halt abnormal blood vessel growth and reduce macular swelling in AMD, diabetic retinopathy, and retinal vein occlusion.
- Vitrectomy Surgery — Microincision vitrectomy is used to repair retinal detachments, close macular holes, and remove cloudy vitreous gel where vision is significantly affected.
Recovery involves adherence to prescribed eye drops and scheduled follow up appointments. Patients receive clear guidance on activity restrictions, head positioning where a gas bubble has been used, and the signs of healing to monitor at home.
Protecting Your Long-Term Eye Health
Proactive management remains the most effective defence against avoidable vision loss. Annual eye screening is strongly recommended for:
- Adults over 50
- Patients with diabetes or hypertension
- Anyone with a family history of retinal disease
Maintaining stable blood sugar levels, wearing UV protective sunglasses outdoors, and following a healthy diet all contribute to long term ocular health.
Your Path to Clearer Vision
Navigating changes to your vision can feel unsettling, but you do not have to manage it alone. Expert evaluation ensures that conditions affecting the retina receive prompt, accurate, and considered attention.

Frequently Asked Questions
What eye conditions do retina specialists treat?
Retina specialists manage a broad range of conditions affecting the inner lining of the eye, including AMD, diabetic retinopathy, retinal detachment, retinal vein occlusion, macular holes, and uveitis. Advanced fellowship training enables both medical and surgical management of these complex conditions.
How do I know if my vision changes require a specialist?
Seek evaluation if you notice sudden flashes of light, a new shower of floaters, distorted straight lines, or a dark shadow obscuring part of your vision. While ordinary blurriness is often corrected with new glasses, sudden or unexplained distortion warrants prompt assessment to rule out serious retinal disease.
Are retinal injections and laser procedures painful?
Most procedures are well tolerated. Anaesthetic eye drops are applied before intravitreal injections and laser treatment to minimise discomfort. Patients typically report only mild pressure rather than pain, and the procedure itself takes only a few minutes.
Will my insurance or MediSave cover retinal treatment?
Many major insurance plans, Integrated Shield Plans, and corporate health networks provide coverage for consultations, diagnostic imaging, and retinal procedures. The clinic team can assist with verifying your coverage and guiding you through the claims process.
How often should high risk individuals have their eyes examined?
Adults over 50, patients with diabetes or hypertension, and those with a family history of retinal disease should have a comprehensive dilated eye examination at least once a year. Regular monitoring allows subtle changes to be detected early, before vision is significantly affected.
