MS/DNB Ophthalmology Thesis: Choosing a Topic and Example Ideas
Last updated: October 2026
Short answer: a good MS or DNB ophthalmology thesis topic is one you can complete well within your residency: a clear question, enough patients in your own hospital, simple and reliable outcome measures, and approval from your ethics committee. Choose a topic that interests you and that your guide supports, rather than the most impressive-sounding one.
How to choose a feasible topic
- Patient numbers: do you see enough eligible patients to reach your sample size in time? Check your hospital's records before committing.
- Equipment: does your department have the machine you need (OCT, specular microscope, topographer), and will you have regular access to it?
- Follow-up: long follow-up is risky in a fixed residency period. Plan for patients who don't return.
- Clear outcome: a simple, measurable outcome (visual acuity, IOP, thickness on OCT) is better than many vague ones.
- Guide's expertise: a guide working in that area can help with design, recruitment and writing.
- Ethics and registration: obtain institutional ethics committee approval before starting. Interventional studies in India are generally registered with the Clinical Trials Registry of India (CTRI). Follow your university's or NBEMS rules.
Example topic ideas by subspecialty
These are starting points to adapt to your department, patients and equipment, not ready-made titles.
| Area | Ideas |
|---|---|
| Cataract | Comparing refractive outcomes of two IOL formulas in short or long eyes; endothelial cell loss with different nucleus techniques; surgically induced astigmatism with different incision sizes; outcomes of SICS vs phaco in dense cataracts |
| Glaucoma | RNFL and GCIPL changes in early glaucoma vs suspects; IOP fluctuation over the day; SLT outcomes as first-line therapy; ocular surface disease in long-term drop users |
| Retina | OCT biomarkers predicting response to anti-VEGF in DME; prevalence of diabetic retinopathy in a defined local population; macular thickness changes after cataract surgery in diabetics |
| Cornea | Microbiological profile of corneal ulcers in your region; outcomes of corneal cross-linking; dry eye in computer users; tear film changes after cataract surgery |
| Paediatrics & strabismus | Prevalence of refractive error in school children; amblyopia treatment compliance; myopia progression with low-dose atropine |
| Neuro & oculoplasty | OCT changes in optic neuritis or idiopathic intracranial hypertension; outcomes of DCR techniques; visual field changes in pituitary tumours after surgery |
A realistic timeline
- First months: choose a topic, review the literature, write the protocol and calculate the sample size (ask a statistician).
- Before recruitment: ethics approval (and CTRI registration where required).
- Middle phase: recruit, collect data in a spreadsheet as you go, and check data quality regularly.
- Final months: analyse, write, and submit well before the deadline.
Frequently asked questions
How do I choose an ophthalmology thesis topic?
Choose a clear question that interests you, with enough patients and equipment available in your department, a simple measurable outcome, and a supportive guide. Feasibility matters more than novelty.
Do I need ethics approval for a thesis?
Yes. Obtain institutional ethics committee approval before collecting data, and register interventional studies with the Clinical Trials Registry of India where required.
What sample size do I need?
It depends on the study design and outcome. Calculate it with a statistician before starting, and check that you can recruit that many patients in time.
