Introduction:

Acute corneal hydrops is a rare and severe complication of keratoconus, a progressive eye condition that causes the cornea to become thin and bulge outward. In acute corneal hydrops, the cornea suddenly swells and develops a sudden and painful bulging protrusion. This condition requires immediate medical attention to prevent further damage to the cornea and preserve vision. This article aims to provide a comprehensive understanding of acute corneal hydrops, including its symptoms, causes, diagnosis, and treatment options.

Symptoms of Acute Corneal Hydrops:

Acute corneal hydrops is characterized by sudden and severe symptoms, which may include:

• Sudden loss of vision: Vision may become significantly blurred or distorted due to the sudden corneal swelling.
• Severe eye pain: The affected eye may be intensely painful, and the pain may be constant and sharp.
• Redness: The eye may appear red due to the increased pressure and inflammation.
• Photophobia: Light sensitivity is common, and bright lights may worsen the discomfort.
• Tearing: Increased tear production is a natural response to the eye irritation and pain.

Causes and Risk Factors:

Acute corneal hydrops is primarily associated with keratoconus, a progressive eye disorder characterized by the thinning and bulging of the cornea. In keratoconus, the cornea assumes a cone-like shape, which makes it more susceptible to sudden swelling and distortion during acute corneal hydrops episodes. Individuals with advanced keratoconus are at a higher risk of experiencing acute corneal hydrops.

Diagnosis and Evaluation:

Diagnosing acute corneal hydrops is based on a thorough eye examination by an ophthalmologist. The evaluation may include:

• Visual acuity test: Testing the clarity of vision using an eye chart helps assess the extent of visual impairment.
• Slit-lamp examination: A specialized microscope, called a slit lamp, is used to examine the cornea and assess its shape and integrity.
• Corneal topography: This imaging test maps the curvature of the cornea and aids in diagnosing keratoconus.
• Intraocular pressure measurement: Measuring the pressure inside the eye helps rule out other conditions and assess the severity of the hydrops.

Treatment Options:

The management of acute corneal hydrops aims to reduce corneal swelling, relieve pain, and promote corneal healing. Treatment options may include:

• Eye patching: Placing an eye patch over the affected eye helps reduce light sensitivity and provides comfort.
• Eye drops: Prescribed eye drops, such as hypertonic saline, can help draw fluid out of the cornea and reduce swelling.
• Pressure-lowering medications: In some cases, medications may be used to lower intraocular pressure and alleviate pain.
• Corneal collagen cross-linking: This procedure strengthens the cornea and stabilizes keratoconus, reducing the risk of future hydrops episodes.

Prognosis and Complications:

The prognosis for acute corneal hydrops varies depending on the severity of the condition and the individual's response to treatment. In some cases, the cornea may gradually improve, while in others, a corneal transplant may be necessary to restore vision. Complications may include corneal scarring, glaucoma, and permanent vision loss.

Conclusion:

Acute corneal hydrops is a severe complication of keratoconus, leading to sudden corneal swelling, severe pain, and vision impairment. Prompt medical attention is crucial in managing the condition and preserving vision. By understanding its symptoms, causes, diagnosis, and treatment options, individuals with keratoconus can seek immediate care to prevent further damage to the cornea and improve the outlook for vision.
