Main
- Retinal detachment is not painful: a veil, flashes or a dark curtain on one side require an ophthalmologist's examination the same day.
- A tear in the membrane starts the process: fluid from the vitreous body seeps under the retina and gradually detaches it from the nourishing tissues.
- At-risk groups: high myopia, eye or head injury, previous surgery and age-related changes in the vitreous body.
- Examination begins with a fundus examination: the pupil is dilated with drops; if the view is difficult, ultrasound and tomography are used.
- The condition is managed by an ophthalmologist: they determine the scope of care, and regular examinations help to notice changes before complaints appear.
What is retinal detachment
Retinal detachment is a condition in which the inner light-sensitive membrane of the eye separates from the underlying tissues. Without timely help, this can lead to permanent vision loss.
What happens in the body
The retina is a thin light-sensitive membrane that lines the eye from the inside and converts light into nerve signals. Beneath it lies a layer of tissue that supplies it with nourishment and holds it in place. When a tear appears in the retina, fluid from the vitreous cavity seeps under it. This fluid gradually peels the membrane away from the underlying tissues, and the area stops receiving nourishment. The longer the area remains detached, the more its cells are damaged. Retinal detachment affects the area responsible for clear vision, so delay here is especially dangerous. If you notice a sudden change in vision, do not put off a visit to an ophthalmologist — time works against the preservation of the membrane.
What causes it to develop
- Age-related changes of the vitreous body: the gel inside the eye thins over time and separates from the membrane, and this often pulls it along.
- Injury to the eye or head: a blow or a fall can create a tear in the membrane through which fluid seeps under it.
- High myopia: with it, the eyeball is elongated and the membrane is stretched more, so tears occur more easily.
- Concomitant retinal diseases or inflammation: they weaken the tissue and create conditions for fluid to accumulate under the membrane.
- Previous eye surgeries: after interventions, the structures of the eye change, and the risk of a tear in the membrane becomes higher.
Who faces this more often
Retinal detachment is more common in people with high myopia, because their eyeball is elongated and the membrane is stretched more. Those who have had an injury to the eye or head, and those who have already had eye surgeries, are also at risk. Age-related changes of the vitreous body increase the likelihood of a tear in older people. Inflammatory and other retinal diseases also weaken the tissue and increase the risk. If close relatives have had this problem, it is worth telling the ophthalmologist at the appointment. Regular vision checks help to notice changes in the membrane before they become irreversible. It is reasonable for people at risk to have an examination by an ophthalmologist more often than others.
What symptoms can there be?
Retinal detachment manifests as visual sensations that a person usually notices in one eye. It is important to recognise these signs in time and understand when emergency care is needed.
How it is noticed at the very beginning
At the very beginning, retinal detachment makes itself known through sudden flashes or lightning in the field of vision. A person may notice these flashes in one eye, more often at the edge of vision, and not attach any importance to them. The appearance of floating spots, cobwebs or floaters is often put down to tiredness after working at a screen. A shadow or curtain covering part of the vision at first seems like a slight blurring that goes away on its own. Symptoms can increase over several hours or days rather than remain unchanged. Because of this, a person postpones a visit to the doctor and loses time when help is especially needed. If such sensations have appeared, one should not wait for them to disappear on their own.
Signs that occur most often
- Flashes or lightning: sudden light sensations in the field of vision that appear in one eye and often serve as the first noticeable signal.
- Floating spots: cobwebs or floaters appearing before the eye may indicate changes inside the eye and require attention.
- Shadow or curtain: part of the field of vision is covered, as if by the edge of a curtain, and this is noticeable when looking to the side.
- Decreased visual acuity: vision suddenly becomes worse, objects are seen indistinctly, and this is already a serious reason for an examination.
- Distortion of shape: objects look curved or not as usual, which is also considered an alarming sign.
- Increase over hours: the sensations intensify over several hours or days, so a visit to the doctor should not be postponed.
When to seek help urgently
Examinations and tests
Examination for suspected retinal detachment is built around fundus examination and clarifying imaging methods. Below is a breakdown of what exactly the doctor looks at during the first appointment, what tests he may prescribe, and what information is worth bringing with you.
How the examination begins
The examination begins with a fundus examination by an ophthalmologist, who uses special instruments and instils drops to dilate the pupil. A dilated pupil opens access to the peripheral parts of the retina, which remain invisible during a routine examination. The doctor assesses the condition of the retina, its position relative to the underlying membranes, and the presence of tears or areas of detachment. If the view is obscured by opacities or a narrow pupil, additional imaging methods are used. Ultrasound examination of the eye helps to see the structures in cases where direct examination is of little value. Optical coherence tomography provides a layered image of the retina and allows its condition in the central zone to be clarified. Perimetry shows how the visual fields have been preserved, and this complements the picture from the examination. Therefore, it is worth coming to the appointment with the pupil already dilated and with time to spare, so that the doctor has time to carry out all the necessary measurements.
What is prescribed and what it shows
What is worth preparing for the appointment
- Discharge summaries: take all previous ophthalmologist's reports so that the doctor can see how the condition of the retina has changed over time.
- Images and results: bring previous tomograms and ultrasound images, if they were done, for comparison with the new data.
- List of complaints: describe in advance when the flashes, veil or loss of part of the visual field appeared, and how this changed.
- Concomitant conditions: report myopia, eye injuries and previous operations, since this affects the assessment of the picture.
- Contact lenses: remove them before the appointment so that the drops for dilating the pupil take effect and the examination is carried out fully.
Which doctor should I see?
Retinal detachment is managed by an ophthalmologist, who determines the type and extent of the process. Further tactics depend on the condition of the eye and require the involvement of a specialist in this field.
Which specialist manages this condition
Retinal detachment is a condition managed by an ophthalmologist, so it is to them that one should go. The doctor examines the fundus and assesses how far the process has spread and which areas are affected. If a specialist in this field is not available nearby, it is reasonable to start with an ophthalmologist at the nearest medical facility where the necessary equipment for examination is available. Such a doctor is able to confirm the condition and, if necessary, refer the patient further, to a department where surgical interventions on the eye are performed. Delay is dangerous because the area of detachment may increase, and along with it the chances of preserving vision decrease. The patient should bring all available records and images so that the doctor can see the dynamics rather than starting the assessment from scratch. If the examination shows that the help of a more narrowly focused specialist is needed, the referral is arranged by the ophthalmologist themselves.
What treatment consists of
- Surgical intervention: used when indicated, when the retina needs to be returned to its correct position, and its extent is determined by the doctor.
- Laser coagulation: strengthens the retina around the tears to limit them and prevent the process from spreading further.
- Introduction of special substances: compositions are injected into the eye cavity that help the retina stay in its place.
- Observation after the intervention: regular examinations show how the eye is healing and whether the achieved position of the retina is maintained.
What depends on the patient themselves
Regular observation by an ophthalmologist is the part of the result that rests on the patient themselves, and not only on the doctor. After the intervention, it is important to come for examinations at the appointed times, even if vision subjectively seems good. A missed visit means that changes in the eye remain unnoticed, and this complicates timely correction of tactics. The patient should honestly tell the doctor about new sensations, for example the appearance of a veil or distortion of objects, because such details change the assessment of the condition. Records of past examinations and interventions are useful to keep in one place and bring to every appointment. If doubts arise about the recommendations, it is better to discuss them with the treating ophthalmologist rather than postpone the visit. Following these simple rules helps the doctor see the full picture and respond to changes in time.
What helps prevent an exacerbation?
Retinal detachment has no specific prevention, but a number of everyday decisions and regular monitoring reduce the likelihood of an exacerbation. Below is what depends on the person themselves and why it matters.
What to change in habits
The everyday habits of a person with risk factors for retinal detachment affect how long the condition remains stable. Protective glasses during injury-prone activities — on a building site, in a garage, on a sports ground — reduce the risk of a blow to the eye that could trigger a tear. Monitoring blood pressure and blood sugar levels is important because their fluctuations affect the state of the eye's vessels and the blood supply to the retina. Sudden bending, lifting heavy objects and jumping from a height create a load that is better avoided with a thinned retina. When visual symptoms appear — flashes, floaters, a curtain on one side — timely consultation with a doctor allows the problem to be noticed earlier. Giving up smoking and reasonable physical activity without overexertion support vascular tone and the general state of the body. Sleeping with the head of the bed raised and avoiding sudden head movements reduce the load on the eyeball. If a person already knows about predisposing changes, they should discuss the acceptable level of activity with an ophthalmologist in advance.
What to keep under control
- Regular examinations by an ophthalmologist: routine check-ups in the presence of risk factors help to notice predisposing changes in time before complaints appear.
- Blood pressure: its stability is important for the eye's vessels, and spikes create additional load on the retina and its blood supply.
- Blood sugar level: its fluctuations affect the state of small vessels, so monitoring helps preserve the blood supply to the retina.
- Eye protection during injury-prone activities: glasses or a mask reduce the risk of a blow that could trigger a retinal tear.
- Visual symptoms: flashes, floaters and a curtain on one side are a reason to consult a doctor without delay.
- Observation diary: records of blood pressure, how you feel and episodes involving the eyes help the doctor assess the dynamics at an appointment.
How often to see a doctor
The regularity of examinations by an ophthalmologist is the main thing a person can set against retinal detachment in the presence of risk factors. Even with good health, routine check-ups are needed, because predisposing changes in the retina do not make themselves known for a long time. The doctor examines the fundus and compares the picture with previous observations, noticing what the person themselves cannot feel. If there have already been tears, degenerative changes or eye surgeries in the past, the interval between visits should be discussed separately. When flashes, floaters or a curtain on one side appear, the visit is not postponed, but made in the near future. For people with high myopia, diabetes mellitus and hypertension, vision monitoring is especially important. Missed examinations lead to the moment for observation being lost, and complaints appearing later. A reasonable approach is to keep the date of the next visit in sight and not to postpone it without reason.
What is worth remembering
Retinal detachment is a condition in which vision is not lost immediately, but gradually. Below are the conclusions that help make the right decision and not lose time.
Key conclusions
Retinal detachment is not painful, so it is easily mistaken for fatigue or temporary blurring. The appearance of a veil, flashes or a dark curtain on one side is a reason to seek help the same day. The delay is explained simply: the longer the retina remains detached from the membrane that nourishes it, the lower the chances of restoring previous clarity. It is impossible to distinguish detachment from other conditions on your own, and attempts to wait it out and rest only postpone help. Retinal detachment does not go away on its own and is not treated with drops or rest for the eyes. If you notice a change in your field of vision, do not wait until it expands or affects the second eye. It is not waiting, but a quick examination by an ophthalmologist that helps preserve vision.
