In medical terms, subconjunctival haemorrhage is an ophthalmic condition that occurs when the tiny blood vessels in the eyes are torn and bleed under the Conjunctiva. It is usually painless and does not harm other parts of the eye. However, looking into a mirror, one can see bright red dots on the white of the eye. These dots look similar to bruises on the skin. To treat a subconjunctival haemorrhage eye, one needs to have a clear understanding of the Conjunctiva. It is a transparent layer in the eyes that lines the eyelids from the inside and provides necessary protection to one of the most vital organs of human beings.
Causes of Subconjunctival Haemorrhage
Subconjunctival haemorrhage is a common phenomenon and can happen to anyone. Following are some of the common causes:
Straining the eyes
Vomiting
Any injury to the eyes due to rubbing
Improper use of contact lenses
Viral infection
Subconjunctival haemorrhage is quite common among newborns. Doctors often relate the cause to the change in pressure during the delivery process. It may also accompany retinal bleeding in some cases right after taking the birth.
While the common causes are discussed, the following are some of the not-so-common reasons behind subconjunctival haemorrhage.
Diabetes
Trauma from any injury or surgery
Constant high blood pressure
Certain medications like the usage of blood thinners, etc.
Any disorder in blood clotting
Symptoms and Diagnosis
Identifying the symptoms of subconjunctival haemorrhage is easy as it includes the following:
Bright red spots and patches on the white of the eye like that of a red eye.
Irritation in the eyes
It does not usually accompany any sign of pain or loss of vision
However, the symptoms may vary from one person to another. Subconjunctival haemorrhage generally cures independently, and the symptoms disappear within two weeks. However, in some cases, it recurs frequently; then one must consult an ophthalmologist.
The doctor will perform the following procedures to find out its root causes:
A physical check-up or regular blood tests may reveal the underlying causes.
The patient's medical history also comes in handy in this matter. It helps in understanding the pattern of this disease for an individual who frequently experiences it.
Risk Factors
Traditionally, subconjunctival haemorrhage does not pose any significant threat to the eyes or overall health of the affected individual. However, the following conditions may be a factor in some cases. These are:
Age and Lifestyle Factors: The risk of getting subconjunctival haemorrhage increases with age, especially after 50 years. Lifestyle factors like overuse of contact lenses, the wrong practice of wearing and removing them, and indulging in strenuous activities also increase the risk of getting this condition.
Medical Conditions: Pre-existing health conditions like hypertension, diabetes, etc., also can pose a considerable risk of getting a subconjunctival haemorrhage eye.
Blood Disorders and Medications: Individuals with bleeding disorders, such as haemophilia or platelet dysfunction, are likely to develop this condition. Additionally, the use of blood-thinning medications, such as aspirin, warfarin, or anticoagulants, can interfere with normal clotting mechanisms, making even minor blood vessel ruptures more noticeable.
Treatment Options
Usually, subconjunctival haemorrhage does not require any dedicated treatment plan as it cures independently in a few days to weeks. However, one can practise some self-care measures and home remedies to accelerate this process. Here are some suggestions –
Avoid further rubbing the eyes
Put an ice pack or cold compress on the affected eye
Opt for artificial tears to cleanse the eyes
In the following cases, one needs to see a doctor –
The symptoms remain for two to three weeks
Any pain or blurry vision
Spotting of blood in other parts of the eye, like in the iris.
Prevention Strategies
Preventing subconjunctival haemorrhage is easy and effective. The following are the most sought-after solutions:
Lifestyle Modifications: Dietary changes can help prevent this disease. Including green leafy vegetables and fruits rich in vitamin A combats this condition and improves overall eye health.
Lowering Stress Levels: Individuals can also fend off this condition by reducing their stress levels. They can practice yoga, meditate, or indulge in hobbies to keep their stress levels low.
Not Rubbing the Eyes: One effective method of preventing this condition is not rubbing the eyes. In case of any discomfort, individuals can instead try washing their eyes with cold water or using eye drops to relieve it.
Protecting the Eyes: Wearing protective eyewear when engaging in activities that could expose the eyes to trauma, such as sports or construction work, helps.
Regular Eye Check-ups: It is essential to go for an eye check at least twice a year to ensure better eye health. At the same time, one must also monitor the eyes for any symptoms of subconjunctival haemorrhage.
Using Contact Lenses Properly: To avoid this condition, it is important to follow the right contact lens hygiene guidelines. Additionally, individuals should refrain from wearing contact lenses for longer periods.
Prognosis and Complications
The blood in the eye affected by a subconjunctival haemorrhage usually clears up within one to three weeks. However, one must consult the doctor if the symptoms worsen with time or recur frequently. Also, people with existing health conditions like diabetes, high blood pressure, etc., should consult a specialist to ensure the condition does not go out of hand.
