Giant Papillary Conjunctivitis (GPC): A Condition Affecting the Eye

Giant Papillary Conjunctivitis, commonly referred to as GPC, is a condition that affects the inner lining of the eyelid, known as the palpebral conjunctiva. It is characterized by inflammation and the development of small bumps, called papillae, on the underside of the upper eyelid.

Causes of GPC

GPC is primarily caused by irritation from contact lenses or similar irritants, such as artificial eyes or exposed stitches. Deposits of proteins or other substances on contact lenses can also contribute to the development of GPC. In some cases, allergies may play a role in the condition.

Symptoms of GPC

The symptoms of GPC typically include:

• Redness and irritation in the lining of the membrane inside the eyelids
• Swelling and bumps (papillae) on the underside of the upper eyelid
• Itching or sore eyes
• Increased eye mucus
• Blurred vision due to thick and possibly stringy mucus in the eyes
• A feeling that there's something in the eyes (foreign body sensation)

Types of GPC

There are two main types of giant papillary conjunctivitis: primary and secondary. Primary GPC is caused by exposure to allergens, while secondary GPC is caused by exposure to irritants.

Progression of GPC

As GPC progresses, its symptoms become more pronounced. At first, the condition may be mild, but if left untreated, it can lead to more severe inflammation and discomfort.

Common Signs and Symptoms of Giant Papillary Conjunctivitis

Giant papillary conjunctivitis (GPC) is a condition that affects the inner lining of the eyelid, causing inflammation and small bumps to form. The symptoms of GPC can vary in severity, but here are some common signs and symptoms:

• Red eyes: One of the earliest signs of GPC is redness in the eyes, which can be accompanied by irritation and itching.
• Itchy eyes: Itching is a hallmark symptom of GPC, and it can range from mild to severe.
• Increased eye mucus: Excess mucus production is another common symptom of GPC, which can cause discomfort and blurred vision.
• Small bumps under the upper eyelid: As GPC progresses, small bumps or papillae may form on the underside of the upper eyelid.
• Blurred vision: In some cases, GPC can cause blurred vision, especially when wearing contact lenses.
• Ocular irritation: Patients with GPC often report ocular irritation, redness, itching, and mucus accumulation on the inner canthus upon awakening.
• Tearing and foreign-body sensation: Additional symptoms of GPC include tearing, a foreign-body sensation, mild to moderate hyperemia, and stringy or sheet-like mucus production.

Causes and Progression

GPC is often caused by chronic irritation under the upper eyelid, usually from contact lenses. As the condition progresses, its symptoms become more pronounced. Early signs and symptoms can include slight irritation and itching or redness, while small bumps may be present on the underside of the eyelid.

Treatment Options for Giant Papillary Conjunctivitis

Giant papillary conjunctivitis (GPC) can be effectively managed with various treatment options, including:

• Topical Therapeutics: Topical mast-cell stabilizers such as cromolyn sodium 4.0% may be prescribed to alleviate symptoms [6].
• Steroid Eye Drops: Steroid eye drops are commonly used to treat GPC, but long-term use can lead to complications like cataract development and higher eye pressure [2].
• Tacrolimus Ointment: Tacrolimus ointment 0.03% has been shown to be effective in treating GPC, as demonstrated by a study published in the Cornea journal [4].

Other Treatment Options

In addition to these treatments, it is essential to address the underlying cause of GPC, such as:

• Discontinuing Contact Lens Wear: Stopping contact lens wear can help alleviate symptoms and prevent further irritation.
• Practicing Proper Lens Care: Regularly cleaning and maintaining contact lenses can reduce the risk of developing GPC.

Differential Diagnoses for Giant Papillary Conjunctivitis (GPC)

Giant papillary conjunctivitis (GPC) is a condition characterized by the presence of large papillae on the superior tarsal conjunctiva. When diagnosing GPC, it's essential to consider other conditions that may present with similar symptoms. Here are some differential diagnoses for GPC:

• Allergic Conjunctivitis: This is a common condition that can cause similar symptoms to GPC, including redness, itching, and swelling of the conjunctiva.
• Bacterial Conjunctivitis (Pink Eye): Bacterial conjunctivitis can cause inflammation of the conjunctiva, leading to symptoms such as redness, discharge, and swelling.
• Chlamydia (Chlamydial Genitourinary Infections): Chlamydia can cause a range of symptoms, including conjunctival inflammation, which may be mistaken for GPC.
• Viral Conjunctivitis: Viral conjunctivitis can cause inflammation of the conjunctiva, leading to symptoms such as redness, discharge, and swelling.
• Toxic Conjunctivitis: This is a condition caused by prolonged use of topical medications, which can lead to irritation and inflammation of the conjunctiva.

Key Points

• GPC should be differentiated from other conditions that may present with similar symptoms. [1]
• Allergic conjunctivitis, bacterial conjunctivitis, chlamydia, viral conjunctivitis, and toxic conjunctivitis are all potential differential diagnoses for GPC. [2-5]
• A thorough medical history and physical examination are essential to diagnose GPC accurately. [6]
