Blood Clot in Eye (Subconjunctival Haemorrhage): Causes & Homeopathy Treatment

The human eye is shielded by the conjunctiva, a thin, moist, and transparent membrane that covers the inside of the eyelids and the sclera (the white part of the eyeball). This outermost protective coating is rich in nerves and tiny, fragile blood vessels. Usually barely visible, these vessels can become engorged and prominent during inflammation.

Because their walls are delicate, these vessels can break easily. When a rupture occurs, a drop of blood becomes trapped between the sclera and the clear conjunctiva, resulting in a subconjunctival haemorrhage. Visually, this appears as a sharply outlined, bright red or dark red patch over the white of the eye. In severe cases, the entire sclera may be covered by blood.

Key Characteristics and Progression

• Painless presentation: Most subconjunctival haemorrhages are discovered spontaneously upon looking in a mirror. They are largely asymptomatic, though some patients report a mild sense of fullness or irritation as the clot resolves.

• Contained bleeding: The blood remains trapped beneath the membrane. If you blot the eye with a tissue, no blood will exit onto the tissue.

• Color evolution: Similar to a skin bruise, the haemorrhage changes color as it heals—typically shifting from red to orange to yellow. However, because the conjunctiva is transparent, it will never turn green, black, or blue like a regular skin contusion.

• Healing timeline: The haemorrhage usually peaks in size within the first 24 hours and slowly absorbs, clearing completely within 7 to 14 days without long-term damage.

Common Causes

Most haemorrhages are spontaneous, but they are frequently triggered by sudden spikes in internal pressure or physical trauma. Key causes include:

• Straining: Heavy lifting, constipation, or vigorous vomiting.

• Respiratory force: A strong, sudden cough or violent sneezing.

• Vascular issues: Hypertension (high blood pressure), bleeding disorders, or the use of medications that inhibit normal blood clotting.

• Trauma: Direct injury to the head or eye, aggressive eye rubbing, or post-surgical complications.

• Infections: Severe acute ocular infections.

Primary Homeopathic Protocol for Subconjunctival Haemorrhage

For the direct treatment of a subconjunctival haemorrhage, the following specific protocol accelerates blood absorption and heals the fragile vascular walls:

Daily Regimen:

• Arnica Montana-Q

• Ledum Palustre-Q

• Dosage: Take ½ cup of water and put 1 drop of each of the above two medicines into it. Drink it slowly. Repeat this dose twice daily (morning and evening).

Fortnightly Regimen:

• Sulphurosum Acidum-30

• Dosage: Take ½ cup of water and put 1 drop of the medicine into it. Drink it slowly. This specific remedy is to be taken only once in a fortnight (every 14 days).

Clinical Materia Medica: Eye Symptoms of Major Remedies

Beyond acute haemorrhages, specific homeopathic remedies correspond to distinct ocular pathologies, modalities, and symptom profiles.

Visual Strain, Neuralgia, and Neurological Symptoms

• Ruta graveolens: The premier remedy for asthenopia (eye strain) from overworking the eyes on fine, detailed work. Symptoms include burning in and over the eyeballs, blurred vision, and letters seeming to run together. (Belladonna and Ammoniacum gum. share similar visual strain profiles).

• Natrum muriaticum: Indicated for muscular asthenopia and blepharitis with lachrymation and scalding. A hallmark symptom is ciliary neuralgia that comes and goes with the sun, alongside letters running together while reading.

• Gelsemium: Acts primarily by paralyzing the third nerve, which supplies the circular fibers of the iris. This paralysis dilates the pupil, causes ptosis (drooping eyelids), strabismus, and diplopia (double vision).

• Belladonna: Stimulates the sympathetic radiating fibers of the iris to overcome the circular fibers, leading to dilated pupils. Presents with sudden, violent pain, red conjunctiva, and eyes that feel swollen, protruding, and full of sand. Features great photophobia; desire to rub the eyes brings relief.

• Physostigma: Contrasts directly with Belladonna by stimulating the third nerve to contract the pupil. It will effectively contract a pupil dilated by Belladonna, but will not contract a pupil paralyzed and dilated by Gelsemium.

• Spigelia: Indicated for ciliary neuralgia with radiating pains and a distinct cold feeling in the eye. (Thuja also features this specific cold sensation).

• Cinnabaris: Characterized by a highly specific ciliary neuralgia: a pain that starts from one canthus (corner), traces around the brow, and ends at the other canthus.

• Comocladia dentata: Severe pain in the right eye as if pushed out of the head, which is uniquely worse near a warm stove.

• Paris quadrifolia: A distinct sensation as if the eyes were drawn back into the head by strings.

• Causticum: Features paralysis of the eyelids, muscular weakness, double vision, and a burning, sandy sensation.

Discharges, Conjunctivitis, and Inflammation

• Apis mellifica: Marked by chemosis (oedematous puffiness of the conjunctiva) and pronounced swelling, especially below the eyes. Unlike Rhus tox, there is less tendency toward pus formation. Relieved by cold applications (whereas Rhus tox is relieved by warmth).

• Rhus toxicodendron: Ideal for traumatic or rheumatic conjunctivitis/iritis with severe pain that is worse at night. Features acrid discharge, edematous swelling, and stiffness of the lids. (Causticum, Gelsemium, and Kalmia also feature lid stiffness).

• Euphrasia: Traumatic conjunctivitis and blepharitis with thick, excoriating tears that scald the cheeks, coupled with photophobia that is worse in artificial light.

  • Differential: In Euphrasia, the eye discharge excoriates while nasal discharge is bland. In Allium cepa, the exact opposite occurs: the nasal discharge excoriates the lip, while the eye discharge is bland.

• Argentum nitricum: Indicated for violent, purulent ophthalmia. The core characteristic is the sheer profuseness of the thick, yellow, bland discharge.

• Pulsatilla: Conjunctivitis featuring a thick, yellow, bland discharge. Specifically indicated for ophthalmia neonatorum or ophthalmia following measles.

• Graphites: Inflammation localized strongly at the canthi. The edges of the eyelids tend to crack and bleed. Associated with inward-turning lashes, excoriating discharges, styes, and corneal vesicles.

• Hepar sulphur: Purulent conditions, including hypopyon (pus in the anterior chamber). Symptoms are aggressively worse from cold air or cold applications.

• Ferrum phosphoricum: Inflamed, red eyes with a sensation of grains of sand under the lids. Pain upon moving the eyes and photophobia exacerbated by artificial light.

• Aconite: The first defense for conjunctivitis resulting from dry, cold winds or a foreign body. Features intense heat, burning, violent aching, and photophobia. If Aconite fails to resolve a foreign body irritation, Sulphur is the follow-up remedy.

Ulcerations, Opacities, and Deep Pathologies

• Kali bichromicum: Corneal ulcers featuring a tendency toward deep perforation, uniquely appearing as if punched out.

• Kali muriaticum: Parenchymatous keratitis and low-grade ulcerations with a dirty yellow base and white mucus discharge. Redness is mild; pain and photophobia are notably moderate or absent.

• Kali sulphuricum: Ophthalmias characterized by a profuse discharge of pus, lid crusts, and neonatal ophthalmia.

• Mercurius: Muco-purulent discharges causing lid ulceration and soreness. Eyes are highly sensitive to touch and intolerant of firelight.

• Mercurius corrosivus: Almost specific for syphilitic iritis. Burning pains, excoriating lachrymation that nearly takes the skin off the cheeks, and severe tearing pains in the orbital bones.

• Aurum metallicum: Syphilitic iritis occurring after the abuse of Mercury. Marked by intense photophobia, corneal ulceration, and a unique visual field defect where only the lower half of objects can be seen.

• Asa foetida: Syphilitic iritis with burning, throbbing pains and bone soreness, heavily characterized by relief from pressure on the eyeballs.

• Kali hydriodicum: Indicated for violent ocular symptoms following the abuse of Mercury.

• Zincum: Corneal opacities, granular lids, pterygium, and amblyopia accompanied by headache with pain at the root of the nose. Pains are worse at the inner canthus.

• Calcarea carbonica: Scrofulous ophthalmia, corneal opacities, and ulcers, always accompanied by general systemic Calcarea symptoms.

Optic Nerve and Retinal Conditions

• Phosphorus: Early-stage cataracts where letters appear red. Features gray atrophy of the optic nerve from an overwrought nervous system. Objects are surrounded by a cloudiness in candlelight or a green halo.

• Arsenicum: Specifically indicated for atrophy of the optic nerve due to tobacco use. Accompanied by eyes that burn like fire, phlyctenulae (blisters) on the cornea, and excoriating discharge.

• Lachesis: Retinal apoplexy and dimness of vision, typically presenting alongside vertigo and evidence of heart disease.

• Cantharis: Distinct symptom where the patient reports that objects look yellow.

• Bryonia: Increased eyeball tension (glaucoma-like), accompanied by a flow of hot tears, photophobia, and dim vision.

Targeted Therapeutics for Styes and Nodosities

• Staphisagria: The leading remedy for itching lid margins, nodosities, chalazae, and styes that appear one after another or ulcerate.

• Silicea: Highly effective for persistent styes or pustular affections localizing around the eyes.

• Other Primary Stye Remedies: When treating styes, always evaluate the constitutional indications for Pulsatilla, Lycopodium, and Hepar sulphur.

When to Seek Immediate Allopathic Care

While generally benign, consult an ophthalmologist immediately if:

1. The haemorrhage does not resolve within two weeks.

2. You experience multiple or recurring haemorrhages, or bleeding in both eyes simultaneously.

3. The eye redness is accompanied by pain, blurry vision, or double vision.

4. You observe concurrent signs of systemic bleeding, such as easy bruising or bleeding gums.

5. The haemorrhage follows significant physical trauma to the eye.
