Main
- Conjunctivitis — inflammation of the mucous membrane of the eye: the white of the eye becomes red, itching, lacrimation and discharge appear, and the cause is distinguished by an ophthalmologist during examination.
- The causes vary: viruses, bacteria, allergy to pollen and animal fur, irritation from smoke and chemicals, violation of the rules for wearing contact lenses.
- Urgently to a doctor: a sharp drop in vision, severe pain in the eye, swelling of the eyelids and face, purulent discharge require immediate help.
- Examination is simple: examination of the eye and eyelids, checking visual acuity and assessing the nature of the discharge; in case of a prolonged course, additional tests are prescribed.
- Prevention: washing hands before touching the eyes, using one's own towel, contact lens care and limiting contact with allergens reduce the risk of exacerbations.
What is conjunctivitis
Conjunctivitis is an inflammation of the thin transparent membrane that covers the front part of the eye and the inner surface of the eyelids. It develops for various reasons and usually manifests as redness, discomfort and discharge.
What happens in the body
The conjunctiva is a thin transparent membrane that covers the front part of the eye and the inner surface of the eyelids. In its normal state it is invisible, moistens the eye and protects it from dust and microbes. When viruses, bacteria or irritants get onto the membrane, the body responds with inflammation. The blood vessels dilate, so the white of the eye turns red and a gritty sensation appears. Immune cells actively fight the foreign agent, and discharge forms in response. Due to the swelling, the eyelids become heavier, and light begins to irritate more than usual. If the cause is not identified in time, the inflammation may drag on and turn into a more persistent form.
What causes it to develop
- Viral infection: most often the inflammation is triggered by respiratory viruses, which are transmitted by airborne droplets and spread easily in close groups.
- Bacterial infection: microbes get onto the membrane of the eye through the hands or from contaminated objects, and then actively multiply in the moist environment.
- Allergic reaction: pollen, animal fur and household dust cause an immune system response that manifests as redness and itching of the eyelids.
- Contact with irritants: smoke, chemical fumes and cosmetics damage the protective layer of the membrane and provoke persistent irritation.
- Wearing contact lenses while breaking the rules: infrequent lens replacement and treatment with low-quality solutions increase the risk of inflammation and damage to the membrane.
Who encounters it more often
Conjunctivitis occurs more often in people who spend a lot of time in close groups or constantly come into contact with irritants. Children in schools and kindergartens exchange viruses and microbes faster than adults, so they fall ill noticeably more often. Medical workers and laboratory staff constantly deal with biological fluids and therefore are at risk. People with allergies to pollen or animal fur encounter inflammation of the membrane during the flowering season or when cleaning the house. Those who wear contact lenses and neglect care rules are also in the zone of increased attention. Workers in chemical production and on construction sites inhale fumes and dust that irritate the eyes. If a person often rubs their eyes with unwashed hands, the risk of inflammation increases noticeably.
What symptoms can occur?
Conjunctivitis is recognised by changes in the eye and eyelids, which may be one-sided or affect both eyes. Below are the typical signs, as well as situations when a visit to the doctor cannot be postponed.
How it is noticed at the very beginning
Conjunctivitis often begins with discomfort that is easily mistaken for tiredness after long hours at the computer or lack of sleep. A person notices that one eye becomes redder than the other, and by the evening there is a feeling as if a small grain of sand has got under the eyelid. In the morning the eyelids may stick together, and to open the eye one has to wash for longer than usual. Tearing increases outdoors, in the wind or in a room with dry air, although this had not bothered the person before. Sometimes itching or burning is added, making one want to rub the eye, but this only increases the irritation. The discharge may be mucous or purulent; it collects in the corner of the eye and leaves traces on the eyelashes. If the redness and the sensation of sand persist for more than a couple of days or affect the second eye, it is sensible to see a doctor rather than wait for it to pass on its own.
Signs that occur most often
- Redness of the eye: the vessels become more noticeable, the white of the eye takes on a pink tinge, and this is usually the first thing others notice.
- Sensation of sand or a foreign body: there is no foreign object, but the feeling that something is in the way under the eyelid persists constantly.
- Mucous or purulent discharge: the discharge collects in the corner of the eye, and its character helps the doctor understand the cause of the inflammation.
- Eyelids sticking together after sleep: overnight the discharge dries, and in the morning the eye can be opened only after washing or a compress.
- Tearing: tears flow for no reason, increase in the wind and in dry air, irritating the skin around the eye.
- Itching or burning: the unpleasant sensations make one rub the eye, which increases the irritation and may introduce an additional infection.
When to seek help urgently
Examinations and tests
Examinations for conjunctivitis are needed to distinguish it from other eye conditions. The doctor selects them based on the examination picture, not on a template.
How the examination begins
The eye examination begins with an examination by a doctor, who assesses the condition of the mucous membrane and eyelids. The specialist looks at how the conjunctiva appears, whether there is swelling, redness and small haemorrhages. Separately, they study the nature of the discharge: it can be mucous, purulent or watery, and this changes the line of thinking. Then the doctor checks visual acuity to understand whether the transparency of the cornea is affected. They ask questions about recent illnesses, contacts with people with similar complaints and how long ago it all started. Such a conversation helps to link the picture of the eyes with the general condition and not to miss accompanying causes. If the examination data are sufficient, no additional investigations are required, and this is a common situation.
What is prescribed and what it shows
What is worth preparing for the appointment
- Discharge summaries: take records from other doctors if you have already sought help with eye complaints, this will help avoid repeating what has been done.
- Previous results: bring the conclusions of previous examinations and vision checks so that the doctor sees the dynamics, and not only today's picture.
- Observations: write down when the redness and discharge appeared, how they changed day by day, this clarifies the course.
- List of questions: formulate in advance what you want to clarify with the specialist, so as not to forget anything in the conversation.
- Information about contacts: recall whether there were people with similar complaints nearby, this is an important part of the conversation about possible causes.
- Readiness for examination: do not apply cosmetics to the eyes and do not instil anything before the visit, so as not to distort the picture.
Which doctor should I see?
This section explains which doctor to consult for conjunctivitis, what happens at the first appointment and what areas of care it involves. There are no prescriptions or regimens here: only guidelines that help you choose a specialist and understand the logic of follow-up.
Which specialist manages this condition
Conjunctivitis is managed by an ophthalmologist, and in children care is often provided by a paediatrician. The ophthalmologist examines the eye using a slit lamp and assesses the condition of the conjunctiva, eyelids and cornea. The paediatrician becomes involved when a child is concerned and, if necessary, refers them to an ophthalmologist. If a specialist is not available nearby, start with a physician at the polyclinic at your place of residence. The physician will take the complaints, examine the eye and decide whether a consultation with an ophthalmologist is needed. At the first appointment, the doctor clarifies how long ago the redness, discharge and discomfort appeared. They also ask about contact lenses, recent colds and similar cases among close contacts. Then the doctor determines the cause of the condition and chooses the direction of care, rather than acting at random.
What treatment consists of
- Selection of therapy by the doctor: the specialist determines the cause of the inflammation and chooses the appropriate direction of care, because there is no universal approach here.
- Eye hygiene: regular washing and a separate towel reduce the risk of transferring the infection to the other eye and to other people.
- Temporary discontinuation of contact lenses: lenses are removed during treatment, as they maintain irritation and hinder recovery.
- Follow-up until improvement: the doctor schedules a repeat examination to make sure the condition is subsiding rather than dragging on.
What depends on the patient themselves
The regularity of follow-up and precise adherence to the doctor's recommendations noticeably affect how quickly the inflammation subsides. If the patient interrupts care at the first signs of improvement, the process may return or become prolonged. Wearing lenses against the doctor's advice maintains irritation and reduces efforts to nothing. A shared towel and dishes during the illness increase the chance of infecting household members. Notes on when symptoms appeared and how the condition changed help the doctor assess the dynamics more accurately. A missed repeat examination deprives the specialist of the opportunity to adjust care in time. If the redness lasts longer than expected or worsens, this should be reported to the doctor without waiting for the scheduled visit. Calm and consistent adherence to recommendations gives the doctor more support for correct decisions.
What helps prevent an exacerbation?
Everyday hygiene and a careful attitude to your own eyes help prevent an exacerbation of conjunctivitis. Below are the habits, observations and control rules that reduce the risk of repeated inflammation.
What is changed in habits
Hand hygiene directly affects the frequency of conjunctivitis exacerbations, since the causative agents most often get onto the mucous membrane from the fingers. Washing your hands before any contact with the eyes should be made an automatic action, especially after being outdoors and travelling on public transport. A separate towel and your own cosmetics exclude the transfer of infection from other people, and you should not use other people's eye products even temporarily. For contact lens wearers, it is important to strictly follow the rules of lens care, change solutions and not wear lenses longer than the prescribed period. If you are prone to allergies, it is reasonable to limit contact with pollen, dust and animal fur in advance so as not to provoke a reaction. The habit of rubbing your eyes with dirty hands goes unnoticed, but it is precisely this that most often triggers inflammation after accidentally touching your face. If irritation does appear, it is useful to give your eyes a rest and not touch them until you have consulted a specialist.
What should be kept under control
- Clean hands: washing before touching the eyes reduces the transfer of causative agents, while the habit of rubbing your face with dirty fingers increases the risk of inflammation.
- Personal hygiene products: your own towel and your own cosmetics exclude other people's microflora, while shared items easily transfer infection from person to person.
- Lens care: regular replacement of the solution and observance of wearing periods protect the cornea, whereas violations often lead to irritation.
- Contact with allergens: if you are prone to allergies, limiting pollen, dust and animal fur reduces the likelihood of a seasonal exacerbation.
- Eye reaction: redness, itching and lacrimation should be noticed immediately, since early observation helps to consult a doctor in time.
How often to see a doctor
A regular examination by an ophthalmologist is needed even when you feel well, because an exacerbation of conjunctivitis often begins unnoticed. The doctor assesses the condition of the mucous membrane and eyelids, checks visual acuity and determines whether there is hidden irritation that the person themselves does not feel. For those who wear contact lenses, monitoring is especially important: improper care can accumulate problems gradually. If you are prone to allergies, it is useful to discuss with the doctor the seasonal periods when the risk of a reaction is higher, and to plan observation in advance. If redness or itching return frequently, a visit helps to understand the cause and adjust everyday habits. Scheduled examinations provide an opportunity to notice changes before they become pronounced and unpleasant. A reasonable approach is not to wait for an exacerbation, but to agree with the doctor on a convenient schedule of check-ups and stick to it.
What is worth remembering
A conversation about conjunctivitis ends not with a list of symptoms, but with an understanding of how to act at the first changes. Below are the conclusions that help make a calm and considered decision.
Key conclusions
Conjunctivitis remains a condition in which attempts to work out the causes on your own often lead to a dead end. People often explain redness and discomfort in the eye as fatigue or a cold and wait for it to pass on its own. Meanwhile, similar manifestations are caused by different mechanisms, and it is the doctor who distinguishes them during an examination. The danger of delay is that the inflammation affects deeper structures of the eye. Increasing pain, reduced clarity of vision and photophobia are especially concerning. Separately, it is worth remembering that conjunctivitis can be contagious, so it is better to keep towels and dishes personal. If nothing is changed, episodes may recur, and the eye will react to things that previously caused no concern. It is more sensible not to choose drops on the advice of acquaintances, but to see a specialist and follow their recommendations.
