1. What is cataract?
Cataract is a gradual loss of clarity of the eye’s natural lens, leading to blurred vision, glare, reduced contrast, and difficulty with daily visual tasks. It is a common age-related condition and one of the most frequent causes of reduced vision.
2. When is cataract surgery recommended?
Cataract surgery is advised when blurred vision begins to interfere with reading, driving, work, mobility, or quality of life after a comprehensive eye examination.
3. Is cataract surgery safe and advanced today?
Modern cataract surgery is highly refined, precise, and commonly performed worldwide. With proper pre-operative evaluation, advanced technology and expert care, outcomes are generally excellent.
4. What type of cataract surgery is offered?
Micro-incision phacoemulsification with foldable intraocular lens implantation may be advised depending on the patient’s eye condition, lifestyle needs, and visual expectations.
5. How soon can vision improve after cataract surgery?
Many patients notice early visual improvement within days, with continued stabilization during the healing period.
6. What is the retina and why is it important?
The retina is the delicate light-sensitive tissue lining the back of the eye. It plays a vital role in clear vision by converting light into signals sent to the brain.
7. Which retinal disorders are commonly treated?
Common retinal diseases include diabetic retinopathy, retinal vein occlusion, age-related macular degeneration, retinal detachment, vitreous hemorrhage, epiretinal membrane, and macular hole.
8. What symptoms require urgent retinal consultation?
Sudden decrease in vision, flashes of light, floaters, distortion, a curtain-like shadow, blind spots, or internal eye bleeding require urgent retina specialist evaluation.
9. What treatments are available for retinal disease?
Depending on diagnosis, treatment may include observation, retinal laser treatment, intravitreal injections, or advanced vitreoretinal microsurgery.
10. What is OCT and why is it useful?
Optical Coherence Tomography (OCT) is a high-resolution retinal scan used to diagnose macular swelling, retinal degeneration, traction, glaucoma-related changes, and many other eye conditions accurately.
11. What is diabetic retinopathy?
Diabetic retinopathy is damage to the retinal blood vessels caused by diabetes. It may affect vision gradually and can progress silently in early stages, making regular diabetic eye screening very important.
12. Can diabetic retinopathy occur even if vision is normal?
Yes. Early diabetic retinopathy may have no symptoms. Regular retinal screening is recommended even when vision appears normal.
13. How often should a diabetic patient get retinal check-up?
Most diabetic patients should undergo a detailed retinal examination at least once a year, or more frequently if advised by the eye specialist.
14. What are warning signs of diabetic eye disease?
Blurred vision, fluctuating vision, floaters, distortion, dark spots, swelling at the macula, or sudden vision loss require prompt examination.
15. Can diabetic retinopathy lead to blindness?
If untreated, advanced diabetic retinopathy can cause serious and permanent vision loss. Early diagnosis and treatment greatly improve outcomes.
16. How is diabetic retinopathy diagnosed?
Diagnosis is made through retinal examination and tests such as fundus photography, OCT scan, fluorescein angiography, and dilated retinal evaluation when required.
17. What treatments are available for diabetic retinopathy?
Depending on severity, treatment may include blood sugar control, retinal laser treatment, intravitreal injections, or retinal surgery.
18. Can good diabetes control help protect eyesight?
Yes. Good control of blood sugar, blood pressure, cholesterol, and regular eye follow-up significantly reduce the risk of progression.
19. Is diabetic retinopathy reversible?
Some retinal changes can be controlled or improved with treatment, but delayed disease may cause irreversible damage. Timely care is essential.
20. I have diabetes but no eye symptoms. Do I still need screening?
Yes. Diabetic retinal disease often develops without pain or early warning symptoms. Preventive diabetic eye check-ups are strongly advised.
21. What is ROP?
Retinopathy of Prematurity (ROP) is a potentially serious retinal condition affecting premature infants due to abnormal retinal vascular development.
22. Which babies should undergo ROP screening?
Premature infants, low birth weight babies, NICU-admitted babies, or babies advised by neonatologists should undergo timely ROP screening.
23. Why is timely ROP screening important?
ROP can progress silently. Early screening allows timely treatment and can help prevent avoidable childhood blindness.
24. Can ROP be treated successfully?
Yes. When detected at the correct stage, treatment such as retinal laser or intravitreal injections may be advised.
25. Are repeat follow-ups necessary in ROP?
Yes. Multiple follow-up visits may be required until retinal vascular development is complete and stable.
