The cause of the hyphema and its severity will determine the course of treatment. For instance, if there are no other issues and your dog only suffered an eye injury, it may not be necessary to treat the eye because it will heal on its own. The root cause must be addressed in order to cure other hyphema causes.
Antibiotic eye drops, topical atropine, and oral NSAIDs are frequently used in treatment (NSAIDS). To avoid rubbing, your dog may need to wear a cone. Treatment will also be required if the ulceration has an underlying condition, such as dry eye.
Prostaglandin, mannitol, and carbonic anhydrase inhibitors may be recommended for the treatment of glaucoma. Surgery possibilities include enucleation, evisceration, anterior shunts, and laser cyclophotocoagulation.
NSAIDs, systemic steroid cream, topical atropine, and prednisone drops are all possible treatments.
In this situation, the eye would need to be enucleated in order to remove the tumor. In some circumstances, additional therapies like radiation or chemotherapy may be employed.
Beta blockers or ACE inhibitors might be administered if it turns out that your dog has excessive blood pressure. The vet will also want to investigate what is causing the hypertension.
Additional testing and even a specialist visit are necessary for other hyphema sources. Your veterinarian will make the necessary referrals for you.

How long does it take for a dog’s hyphema to go away?
The underlying source of the bleeding and the degree of injury to the intraocular structures that resulted from it both have a significant role in the prognosis for hyphema. Generally speaking, animals with retinal illness, such as vitreal, choroidal, or retinal hemorrhages or retinal detachments, have a grave to poor prognosis for eyesight. 1, 2, 36 The condition may take up to a week to go away in situations of simple hyphema with little amounts of blood; however, if the hyphema persists or reappears, more diagnostics should be carried out to look into another potential underlying disease. When neoplasia is the main issue, animals should undergo enucleation; nevertheless, other diagnostic procedures such thoracic and abdominal radiographs should be carried out to check for metastases. The prognosis is poorer when metastasis is found, however enucleation may still be able to offer the patient some relief and palliative care. 1, 2, 36 Animals with persistent hyphema frequently experience secondary issues like glaucoma, and their chances of recovering their vision are typically poor. 1 Smaller levels of hyphema should be treated and the prognosis should be reevaluated in patients who do not have considerably elevated IOP once the hyphema has subsided and an accurate assessment of the integrity of the intraocular structures can be made. 1, 36 The outlook for these patients’ vision is the best.
Can dogs with hyphema be treated?
Hyphema may also be a sign of a number of systemic and ocular conditions, some of which may be fatal. Therefore, it is crucial to diagnose it and treat it appropriately.
Diagnosis
Diagnostic imaging including X-rays and ultrasound testing, lab tests, and hematology and blood biochemistry tests are all used to identify hyphema.
To include or rule out potential causes for the ailment, a full physical examination will be performed along with a complete medical history.
Typical diagnostic techniques and testing include:
- platelet count and whole blood count
- serum biochemistry to assess protein levels in the serum
- Blood coagulation functions are evaluated with coagulopathy assays.
- the heart rate
- urine testing to rule out kidney disorders
- X-rays of the abdomen and chest
- Ocular ultrasounds (ultrasonography) are used to examine the front of the eye and determine whether retinal detachment, lens displacement, abnormal masses, or vitreal hemorrhage are possible.
Abdominal ultrasounds, head and eye orbit X-rays to look for previously undetected traumatic injuries, and hormonal tests (assays) of the adrenal glands are further sophisticated diagnostics that could be done. A bone marrow aspirate, which removes the fluid from the bone marrow, can also be used to check for bone marrow malignancy.
Treatment
The goals of hyphema treatment include reducing inflammation and getting rid of the underlying issues that lead to bleeding in the eye’s anterior chamber.
The typical methods of treatment are:
- using corticosteroids in the form of eye drops or cream to treat inflammation brought on by bleeding
- Atropine eye drops help enlarge the pupil and reduce lens and iris adhering
How is hyphema treated?
You only need at-home treatment if the hyphema is of a lower grade and isn’t contributing to any other symptoms or problems. Conservative therapies typically consist of:
- Rest: While your eye is healing, stay away from strenuous activity that could increase the pressure inside of it.
- Putting on an eye patch: A patch will shield your eye from further irritants and promote relaxation as it recovers.
- Elevating your head: Doing so will help the accumulated blood flow away from your eye and back into your body.
Hyphema surgery
Only about 5% of those who have hyphema require surgery to fix it. You may require surgery if the pressure and severe bleeding inside your eye don’t start to subside in 24 hours or if your symptoms are serious enough to permanently harm your eye.
How to take care of myself?
While you are recovering from hyphema, pay attention to any instructions your doctor or surgeon may give you. If you have a patch to wear, be careful to do so for the recommended amount of time and frequency. In a few days, hyphema normally goes away on its own.
The first five days after developing hyphema are crucial, even if conservative treatment is all you need. You have a greater risk of aggravating your eye once more, which could lead to new bleeding. Serious issues including irreversible visual loss could result from this.
Canine hyphema lead to blindness?
Depending on the etiology of the hyphema, 11.1 to 100% of the eyes eventually lost their eyesight. Overall, hyphema was present in 36.4% of dogs related to a systemic etiology, 32.9% secondary to local ocular disease, 26.1% secondary to trauma, and 4.5% secondary to idiopathic causes.
What does hyphema look like in a dog?
Hyphema, which is the presence of blood in the canine eye’s front (anterior) chamber, is a sign of either a severe ophthalmic or systemic condition. The front chamber’s blood volume might change. Mild hyphema might simply show up as a pinkish-red stain on the fluid at the front of the eye or as red blood that has spilled out onto the chamber’s floor. When the chamber is completely filled with blood and the animal is rendered blind, it is considered severe hyphema.
Hyphema typically results from bleeding of the iris blood vessels, although blood can also come from the choroidal blood vessels, the retina, the ciliary body, or the tissue layer behind the iris.
What is hyphema’s course of action?
Typically, topical medicine is used to treat isolated hyphemas. The impact of topical corticosteroids (or systemic for severe cases) on the risk of rebleeding is questionable, but they may lessen the related inflammation. Patients with severe ciliary spasm or photophobia may benefit from topical cycloplegic medications. Topical aqueous suppressants are first-line pressure management medications when intraocular pressure is elevated (beta-blockers and alpha-agonists). If topical therapy is unsuccessful in reducing the pressure, systemic carbonic anydrase inhibitors and hyperosmotic medications (acetazolamide or mannitol) may be needed. If this is the case, surgery will probably be necessary for the patient.
Since carbonic anhydrase inhibitors may worsen the sickling propensity in the anterior chamber of individuals with sickle cell hemoglobinopathies by raising aqueous acidity, it’s vital to highlight that these medications are typically avoided in the treatment of pressure rises.
[2] Additionally, systemic hyperosmotic medications should be avoided in dehydrated sickle cell disease patients since they may cause a sickle crisis.
Adrenergic agonists with substantial alpha-1 activity, such as iopidine or apraclonidine, are also a worry in people with sickle cell disease because they may increase intravascular sickling through their vasoconstrictive and subsequently deoxygenating qualities.
[6]
Numerous studies have suggested the use of systemic and topical aminocaproic acid (ACA) as therapy alternatives to help hyphema sufferers prevent subsequent hemorrhage.
[1]
[2][4]
[11] ACA is a lysine derivative and analog that inhibits plasmin, a crucial protein enzyme involved in fibrinolysis, through competitive inhibition. The suppression of naturally occurring clot lysis for 5–6 days might be helpful if additional hemorrhages are the result of a clot’s lysis and retraction, which has resulted in an obstruction of the traumatized vessel. This will allow the damaged blood vessel to more fully recover its integrity. [4] There is also tranexamic acid (TA) as an option. With fewer adverse effects than aminocaproic acid, it is more effective. [12] Antifibrinolytics like ACA and TA are not frequently used to treat hyphemas but may be helpful in patients who are more susceptible to rebleeding or other issues related to hyphemas.
Surgery may be required if medication management of the intraocular pressure is insufficient, or if the patient experiences new ocular problems (corneal blood staining, rebleeding).
How long does it take for a dog’s eye damage to heal?
How long does it take for a dog’s eye damage to heal? This could take anything from a few days to weeks, depending on the sort of injury. Simple corneal ulcers should heal in 7 days, while surgically repaired eyelid injuries should recover in 7–10 days.
Will a dog’s eye recover on its own?
Get him down to us to check it out first, please! Because dogs’ eyes are so delicate, it’s crucial that we can treat any injuries right away.
Grass blades, thorns or brambles, a cat’s claws, or any other hard or sharp object will scratch the cornea (the front layer of the eye). This kind of injury is hence referred to as a corneal ulcer or corneal laceration. The most frequent cause is racing through dense grass or underbrush while not blinking quickly enough. Another very typical occurrence is for a grass seed, grass blade, or even clump of hair to get stuck behind the eyelid and scrape the eyeball every time it moves.
When a dog comes across an aggressive or very fearful cat, the cat may frequently make a swipe with its claws, which may draw the dog’s attention.
The inability of dogs with protruding eyes, such as Pugs, to fully expand their eyelids to cover the entire area of the eye, is the other major issue. These canines inevitably have a larger chance of suffering eye damage!
The most typical symptoms are:
- swollen eyes
- the membranes surrounding the eye are red.
- eyelid tissue that is swollen
- the eye’s outer surface is milky or blue.
- Rub and suffering
- Keeping one eye shut
Most frequently, dry eye (keratoconjunctivitis sicca), in which there is insufficient tear production, which causes the cornea’s center to dry out and crack or ulcerate.
We’ll try to determine the extent of the injuries first. However, most of the time, we can use local anesthetic to alleviate the pain and enable us to inspect the eye without having to sedate the dog. Once the injury and the rest of the eyeball have been thoroughly examined, we’ll apply a special dye called fluorescein, which adheres to injured corneal cells and reveals the depth and width of the damage. The optimum course of treatment can then be chosen.
The majority of corneal wounds are rather small and heal quickly with minimal care. This typically entails taking some painkillers for a week or so along with a brief course of antibiotic eye drops. We can typically just continue the treatment for another week or so if the damage is mending but not completely gone by the end of this period. Because the infection in the wound is typically the only thing preventing it from healing naturally, antibiotics are used.
Additional medications and therapies, most frequently plasma drops, are offered to promote healing. This eyedrop contains pro-healing, anti-infection, and anti-wound breakdown substances that are derived from the dog’s own blood (we’ll take some if we need to!). Other possibilities include bandage lenses and EDTA drops, which perform a similar function (soft contact lenses that will protect the eye while it heals).
A particularly severe corneal laceration may require surgery, frequently a pedicle flap to use a portion of the eye’s lining as a tissue graft to shield and nourish the area and enable healing.
The wound could develop into a slow-healing ulcer if the eye doesn’t heal normally. In this situation, we may either employ the aforementioned pedicle flap or graft, or do surgery to promote healing (such as a grid keratotomy).
It’s really uncommon to encounter a scratched cornea that won’t improve after trying one or more of the cutting-edge remedies we currently have!
Bring your dog in as soon as you can for a checkup if you suspect that they may have an injured eye.
Can a dog’s torn eye recover?
The epithelium regenerates from the borders of the ulcer and extends over the defect, causing the majority of corneal ulcers to heal quickly within a few days. Some dogs, meanwhile, do not go through this healing process and end up developing an SCCED. Although it is superficial and not infectious, this kind of corneal ulcer does not recover.
Can hyphema last a lifetime?
A hyphema is a gathering or pooling of blood in the eye’s anterior chamber (the space between the cornea and the iris). The iris and pupil may be completely or mostly covered in blood, partially or totally obstructing vision.
A hyphema typically hurts. Untreated, it may result in lifelong vision issues.
An rise in intraocular pressure and a hyphema are typically linked to eye injuries (the pressure inside the eye). However, it could suddenly arise in kids with other illnesses such sickle cell anemia or hemophilia.
If hyphema occurs, immediate medical intervention is required. When participating in sports, eye protection is the greatest strategy to prevent hyphema. Additionally, never ignore an eye injury. Visit your eye doctor even if there is no bleeding.
