Patient Script
For the friend playing the patient role
Character Overview: You are Marianne Aldridge, a 31 year old dental receptionist on maternity leave, and you are on a video call to the doctor about your first baby, Linus, who is 4 weeks old. You live in a two bedroom flat with Linus and your husband Tobias, who works shifts as a railway signaller, so he is often asleep when you need a second pair of eyes. Your mother, Dilys, lives twenty minutes away and visits most afternoons. She raised three children and is very sure of herself. You are conscientious, a little anxious, and you do not want to be told you are fussing. You are also quietly afraid that you have missed something or let him get an infection by not keeping things clean enough. You speak warmly and a bit quickly, and you check that you are making sense. You never name what Linus has.
Opening Sentence: "Hello doctor, thanks for fitting us in. It's my son Linus, he's four weeks old. His left eye has been watering since he was born and it goes sticky overnight. My mum says he needs antibiotic drops and I don't know whether she's right, so I thought I'd better ask."
History if Asked (Data Gathering Phase)
- ●When it started: "I noticed it when he was about five days old. The left eye looked wet all the time, like he'd been crying, even when he was calm. It has been like that on and off ever since, so about three weeks."
- ●What the eye looks like through the day: "Watery mostly. A tear sits on the lower lid and runs down his cheek, especially when he's been crying or when we go outside. Some days it's wetter than others."
- ●The stickiness: "In the morning there is a bit of yellowish crust along his lashes. I wipe it off and the eye opens by itself, it's never been stuck shut. In the daytime it may go a bit gooey again, but it comes and goes. It is a small amount, not like pus pouring out."
- ●Colour of the eye and the lid: "The white of the eye is white, I've looked properly. It has never been red or pink. The eyelids aren't puffy and there is no swelling or redness at the inner corner by his nose."
- ●The other eye: "The right eye is perfectly dry and clear."
- ●Pain, light and the way he looks: "He doesn't seem bothered by it. He doesn't squeeze it shut in bright light or rub at it. He follows my face with both eyes. The dark part of both eyes looks clear and the same size to me."
- ●Feeding and general health: "He is breastfed, feeding well every two to three hours, and has plenty of wet and dirty nappies. The health visitor weighed him last week and said he is putting on weight nicely. He has had no temperature, no vomiting, and he's not sleepy or floppy. He's a happy baby."
- ●What has been tried: "I wipe the eye with cooled boiled water and a fresh piece of cotton wool each time, from the nose side outwards, a few times a day. I washed my hands first. It hasn't made much difference. I haven't put anything in the eye."
Ideas, Concerns, Expectations
Gating note: Marianne does not raise any of the following herself. Each part comes out only when the doctor asks what she thinks is going on, what is worrying her, or what she was hoping for.
- ●Ideas: She thinks it is an eye infection that has not cleared because she hasn't been giving him anything for it. She has heard that infections in newborns can be serious, and she wonders if it is why the eye is wet. "I assumed it must be an infection, because it goes crusty. But the eye isn't red, so I wasn't sure."
- ●Concerns: Her main fear is that it will spread to his other eye or damage his sight, and that she has caused it by not being clean enough. She also dreads a family row, because her mother has told her she is being negligent. "I keep worrying it will go into the other eye, or that it could affect his sight. And part of me thinks it's my fault for not doing something sooner."
- ●Expectations: She came hoping for antibiotic drops, mostly to settle the matter with her mother, though she would be relieved to be told she does not need them. "My mum says it's what you do. But if you tell me it's not needed, I'd rather not put things in his eyes. I just need to know what to do."
If Asked: Birth, Pregnancy and Family History
Gating note: Marianne answers each of these plainly when the doctor asks about it.
- ●Pregnancy and birth: "Full term, forty weeks and one day. A normal vaginal delivery. He weighed 3.4 kilos and went home the next day. He did not need any special care."
- ●Infections in pregnancy or at the birth: "My antenatal tests were all normal. I had no infections that I was told about, no sexually transmitted infections, and no cold sores or genital sores. I wasn't given antibiotics in labour."
- ●Newborn checks: "They checked his eyes at the hospital and I was told everything was fine. His six to eight week check is not booked yet."
- ●Family history of eye problems: "None that I know of. My mother says my brother's eyes watered as a baby and it cleared up on its own, but nobody was treated."
- ●Other illness at home: "Nobody has a cold or sore eyes."
- ●Allergies and medicines: "Linus has no allergies and takes nothing. I take no medicines apart from vitamin D."
Social History and Lifestyle Impact
- ●Home: Lives with Tobias in a flat. He is on nights this week, so he is asleep in the daytime. She is tired.
- ●Support: Her mother Dilys visits most afternoons and has strong views. Dilys kept a half used bottle of chloramphenicol eye drops from her own sore eye last year and offered it. Marianne has not used it and has put it out of reach. If asked, she says she did not like to say no outright.
- ●Baby care: Washes her hands before touching his face. Has not put breast milk or tea bags near the eye, although her mother mentioned breast milk as a remedy.
- ●Availability to be seen: She can bring Linus to the surgery today or tomorrow. Tobias can drive them.
If Asked: Associated Symptoms
Gating note: Marianne answers these only when asked. Every one is negative unless stated.
- ●If asked about redness of the white of the eye or of the eyelids: "No. The white of the eye has never looked red."
- ●If asked about a lump or swelling by the nose or inner corner of the eye, or the lid being hot or tender: "No, nothing like that. It looks flat."
- ●If asked about bright light bothering him, the eye looking big, bulging or cloudy: "No. Both eyes look the same size and clear."
- ●If asked about fever, poor feeding, being unusually sleepy or irritable: "No to all of those. He's feeding well and his temperature has been normal when I took it."
- ●If asked about a rash, sticky discharge in the other eye, or a cough or breathing trouble: "No. He has no rash and he is breathing normally."
Responses to Management (The Negotiation Phase)
- ●If the doctor explains that Linus probably has a blocked tear duct and that antibiotic drops are not needed:
- ●Reaction: Relieved but cautious. "So it isn't an infection? But it goes crusty." She accepts once told that crusting is common with a slow draining tear duct and that drops do not unblock it. "My mum is going to say I should have got drops. What do I tell her?" If given a simple way to put it, she says she will use it.
- ●If the doctor explains how and why to massage the tear duct and clean the eye:
- ●Reaction: Interested and practical. "How hard do I press? I'm terrified of hurting him. How often, and for how long?" She asks the doctor to repeat it in plain words.
- ●If the doctor asks to see Linus in person, or checks when his routine 6 to 8 week check is due:
- ●Reaction: Agreeable. "Yes, I'd feel better if someone looked at him properly. I can come today or tomorrow." If the doctor says it can wait for the planned check, she accepts as long as she is given clear signs to watch for.
- ●If the doctor says it usually clears by itself and talks about how long it can last:
- ●Reaction: Worried about the wait. "Months? Does it just carry on watering?" If told that most clear in the first year and a specialist can help if not, she asks, "Will he need an operation?" She is calmed when told this is uncommon.
- ●If the doctor mentions the leftover drops or the grandmother's advice:
- ●Reaction: Embarrassed. "Mum gave me some of her old drops. I haven't used them." She agrees not to use them once the doctor explains, and asks for help keeping the peace. "Can I tell her you said no drops?"
- ●If the doctor gives safety netting, or says to return if it changes:
- ●Reaction: Wants specifics. "What would worry you? What do I do if it happens at night?" She repeats the signs back accurately and says she will go to the surgery or urgent care straight away if the eye goes red, swells or he becomes unwell. If the advice is vague, such as "if it gets worse", she asks "Worse how?"

Clinical Learning Points
The Core Dilemma and the Model Plan
- ●Linus is 4 weeks old with a left eye that has watered since about day five, a little yellowish crust in the morning, a white eye, normal lids and a well baby. His mother's own mother says he needs antibiotic drops. The station tests telling a blocked tear duct from an infected eye in a very young baby, holding the line on drops, teaching lacrimal massage and cleaning, and giving red flags in words a first time mother can use.
- ●The model plan has seven parts. Take a focused history that separates watering from inflammation. Confirm no red flag for ophthalmia neonatorum, an infected tear sac or a structural cause. Reach a working diagnosis of congenital nasolacrimal duct obstruction. Decline antibiotic drops. Teach cleaning and lacrimal sac massage. Arrange examination in person. Give specific safety netting and a referral point if it persists.
- ●Acceptable alternatives: examining Linus face to face today or tomorrow, or confirming his eyes will be examined at the planned 6 to 8 week check with a clear safety net, are both reasonable. Massage has limited evidence, so a candidate who recommends cleaning alone and explains why also passes this part. Both a referral at around the first birthday and an earlier referral if infections recur are reasonable.
Taking the History: Watering Versus Inflammation
- ●The key discriminator is the white of the eye. A blocked duct gives a wet eye with a tear sitting on the lid, and intermittent crust or mucus that wipes away. The conjunctiva is white and the lids are normal. Conjunctivitis gives a red, inflamed eye with persistent discharge.
- ●Ask when it began, which eye, whether the tears are constant or only with crying, how much crust there is, and whether the eye opens by itself. Ask directly about redness of the white of the eye and the lids, lid swelling, and the other eye.
- ●Ask about the inner corner beside the nose. Redness, swelling, warmth or tenderness over the tear sac suggests an infected sac (dacryocystitis) or a swelling of the sac present from birth, and needs prompt assessment.
- ●Ask about wellbeing: feeding, wet nappies, weight gain, temperature and alertness. A well baby makes serious infection unlikely.
Excluding Conditions That Need Urgent Assessment
- ●Ophthalmia neonatorum is conjunctivitis in the first four weeks of life and may be infectious or non infectious. CKS Conjunctivitis infective (revised October 2022) lists it among the situations that need urgent ophthalmology referral, along with suspected gonococcal or chlamydial conjunctivitis. A red sticky eye in a baby this age is therefore not managed by drops over the phone.
- ●Ask about the birth and the mother's health: term vaginal delivery, antenatal screening, any sexually transmitted infection, genital herpes, and antibiotics in labour. Linus's answers are all reassuring. Chlamydial conjunctivitis most often appears 5 to 12 days after birth (CDC STI Treatment Guidelines 2021), and these infections give a red, sticky eye, which Linus has never had. Ophthalmia neonatorum is not on the current UKHSA list of notifiable diseases for England, so no notification is needed, though a confirmed sexually transmitted cause means the mother and her partners need treatment.
- ●Congenital glaucoma is rare but is the diagnosis not to miss in a baby with a watering eye. The features are light sensitivity, a large or cloudy cornea, squeezing the eye shut and a baby who does not seem comfortable. Linus has none of them. His newborn examination recorded normal red reflexes, and this will be checked again at 6 to 8 weeks.
The Diagnosis: Congenital Nasolacrimal Duct Obstruction
- ●A tear leaves the eye through two small openings near the inner corner, passes down the nasolacrimal duct and drains into the nose. In many newborns the lower end of the duct has not fully opened, so tears collect on the lid and run onto the cheek.
- ●Watering often starts in the first weeks, may come and go, and may be worse with crying, wind or a cold. A small amount of sticky or yellowish discharge on waking is common because tears and debris pool in the lashes, and does not by itself mean infection.
- ●Many babies are affected, usually on one side. The diagnosis is clinical and no tests are needed in primary care.
Why Not Antibiotic Drops
- ●Antibiotic drops treat bacterial conjunctivitis, not a blocked duct. The eye is not inflamed, so drops would not help. A candidate who explains that the crusting is from tears pooling, not infection, will give Marianne a reason her mother can accept.
- ●If Linus later develops a red eye with persistent pus, the picture changes. In a baby under four weeks that is an urgent ophthalmology assessment (see section 3). In an older baby it may be bacterial conjunctivitis, which is managed on its own guidance. The candidate should say this so that the decision not to prescribe is clearly about the present picture.
- ●The leftover drops in the grandmother's cupboard should not be used. They were prescribed or bought for another person and are not appropriate for a newborn. Putting breast milk, tea or other substances into the eye is not recommended and is not needed. Say so kindly, since Marianne is trying to keep the peace.
Cleaning and Lacrimal Sac Massage
- ●Cleaning: wash hands, then wipe the lids gently with cooled boiled water and clean cotton wool, from the inner corner outwards, with a fresh piece for each wipe, as often as needed to remove crust. Marianne already does this, so tell her it is right.
- ●Massage: with a clean finger, press firmly but gently over the side of the nose just below the inner corner of the eye, where the tear sac lies, and stroke downwards a few times, a couple of times a day. The aim is to help the duct open. The eyeball itself should not be pressed. AAPOS lists massage as a home treatment, though the evidence is limited, and it is simple and low risk.
- ●Make it practical. Link it to nappy changes, give her the words to remember, and ask her to say back how she will do it.
Outlook and Follow Up
- ●Most blocked tear ducts open by themselves in the first year: AAPOS gives about 90 percent. Linus will probably have watering and crusting that comes and goes in the meantime.
- ●Review at the 6 to 8 week check, or earlier if he is seen in person. If the problem has not settled by about his first birthday, or if he gets repeated eye infections or an infected tear sac, refer him to paediatric ophthalmology. AAPOS advises that probing may be considered if the blockage has not improved after 12 months. Referral timing varies with local pathways, so around the first birthday is a reasonable, not a fixed, point.
Safety Netting
- ●Specific signs that need review the same day: the white of the eye turning red, swelling of the eyelids, a red, swollen or tender inner corner, thick pus that keeps coming back, fever, poor feeding, unusual sleepiness, and an eye that looks cloudy, larger than the other or hurts him in bright light.
- ●Say where to go: the surgery in the day, and out of hours the urgent care or NHS 111 service, or the emergency department if he is unwell or feverish. Tobias is on nights, so Marianne needs a plan that does not depend on him.
- ●Ask her to repeat the signs back. Vague advice such as "come back if it gets worse" is a common cause of delay.
Talking to a New Mother and Her Own Mother
- ●Marianne is guilty and anxious. Her worries are that it will spread or damage his sight, and that she caused it. Say plainly that a blocked tear duct is common, is not caused by poor cleaning, and does not threaten his sight.
- ●Her mother is a strong presence. Acknowledge that her mother wanted to help, then give Marianne simple words: drops are for a red, infected eye, and they do not open a tear duct. She may feel more confident if she can say the doctor advised this.
Common Mistakes in This Station
- ●Prescribing or approving antibiotic drops because the eye is sticky, or telling her the leftover drops are fine.
- ●Treating it as an infection by phone without asking whether the white of the eye is red, or failing to recognise that a truly red, purulent eye in a baby under four weeks needs urgent assessment.
- ●Not asking about the inner corner, light sensitivity or a cloudy or large eye, or about the birth and maternal infections.
- ●Making a firm diagnosis from video alone with no examination or review planned, or forgetting massage.
- ●Giving no outlook and no point at which to refer, or vague safety netting.
- ●Ignoring her mother's influence and her guilt, so she leaves reassured by the doctor but still under pressure at home.
