What is the treatment for allergic conjunctivitis?
Treatments for allergic conjunctivitis include antihistamines and mast cell stabilizers. Allergic conjunctivitis is the medical term for an eye allergy. It develops when your eyes come into contact with something you’re allergic to. When that happens, your body releases chemicals called histamines.
What is the conjunctiva?
The conjunctiva is a clear layer of tissue that lines the eyelids and covers the whites of the eyes. When an allergic reaction causes your conjunctiva to swell, you might experience symptoms like: People of any age can get allergic conjunctivitis. You may be more prone to it if you have family members with allergies.

What is the best treatment for allergic conjunctivitis?
Allergic conjunctivitis affects a large percentage of the population and is believed to be increasing in prevalence.2The symptoms of AC contribute to decreased productivity and quality of life, and the effects of AC can be markedly exacerbated by comorbid conditions, such as allergic rhinitis or dry eye. Topical ocular antihistamine–mast cell stabilizer formulations are first-choice AC medications because these formulations rapidly alleviate acute ocular signs and symptoms, and reduce or prevent late-phase responses perpetuated by mast cell degranulation. Furthermore, these dual-acting agents exhibit a high degree of overall effectiveness and are well tolerated for chronic use.
What is the conjunctiva?
The conjunctiva is a transparent, vascularized mucous membrane that covers and lines the sclera and eyelids, and protects the ocular surface. This membrane contains abundant mast cells, which mediate the inflammatory immune response elicited by AC. Compared with the control subjects, conjunctival mast cell counts are increased by >50% in patients with various forms of AC, including SAC (both in season and out of season).18–21Further, in healthy control subjects, mast cells are restricted to the conjunctival stroma (i.e.,lamina propria), whereas migration to the conjunctival epithelium is evident in patients with SAC.18,20
What is AC in ocular symtoms?
Signs and symptoms of AC can decrease quality of life, interfere with productivity, and lead to considerable economic burden. Consistent suppression of conjunctival inflammation is necessary for managing AC, but currently available medications require frequent administration and exhibit limited duration of action.
How many people with allergic rhinoconjunctivitis receive immunotherapy?
In the Allergies, Immunotherapy, and Rhinoconjunctivitis study, only 22% of patients with allergic rhinoconjunctivitis reported receiving allergen immunotherapy.37Further, many patients do not pursue desensitizing immunotherapy options recommended by their health care providers, and only a fraction of these patients complete therapy.38Results of the Allergies, Immunotherapy, and Rhinoconjunctivitis study indicate that this may be because of treatment inconvenience, cost, or ineffectiveness.37The availability and efficacy of topical treatments for acute AC symptoms may also be a factor; many patients reported using prescription or nonprescription medications to manage their symptoms.37
How to treat AC?
The most common treatment approach for management of extant AC is use of a topical pharmacologic medication (e.g.,a dual-acting antihistamine–mast cell stabili zer agent) to reduce inflammation combined with nonpharmacologic remedies (e.g.,cold compresses or artificial tears) to provide temporary symptomatic relief.23,32Although this approach is effective for most patients with mild symptoms of SAC or PAC, none of these medications last a full 24 hours. In addition, patients who experience moderate to severe symptoms that significantly interfere with daily activities and quality of life may require more effective and longer-lasting treatment. There have been few recent developments in strategies for treatment of AC. Existing drug classes and immunotherapies have been modified to improve safety and efficacy profiles, but AC remains inconvenient and costly to manage. A key limitation of many topical AC treatments is the need for multiple daily instillations to maintain symptomatic relief.2,16,33
What is targeted immunotherapy?
Targeted immunotherapy, in which the immune system is desensitized to triggering allergens through chronic exposure to low doses of specific allergens delivered subcutaneously or sublingually, is intended to desensitize individuals to triggering allergens and prevent the activation of inflammatory signaling pathways .34,35Allergen immunotherapy is indicated for patients with inadequate response to pharmacologic agents or who experience unacceptable adverse effects from medications.36Over time, immunotherapy can effectively reduce immune responses to seasonal or environmental allergens in sensitized individuals to prevent the activation of inflammatory cascades and development of AC. Immunotherapy improves symptoms of SAC (e.g.,itchiness, watery eyes, and red eyes) and may reduce AC medication use.34,35Despite the effectiveness of immunotherapy, this treatment approach is not used by most patients.
What is the best treatment for extant AC?
Topical pharmacologic treatments are the most common approach for managing extant AC; however, most available medications require multiple daily instillations. Dual-acting antihistamine-mast cell stabilizing agents are currently considered first-line therapeutics for AC because they provide acute relief of signs and symptoms and block persistent inflammation to promote regression of AC. Recent studies of a newly-developed, higher-concentration formulation of a dual-acting antihistamine-mast cell stabilizer have demonstrated that this formulation provides a 24-hour duration of action with once-daily dosing.

What is the best treatment for ocular allergies?
Corticosteroids. Corticosteroids remain among the most potent pharmacologic agents used in the treatment of chronic ocular allergy. They act at the first step of the arachidonic acid pathway by inhibiting phospholipase, which is responsible for converting membrane phospholipid into arachidonic acid.
Why do you take antihistamines?
Systemic and/or topical antihistamines may be prescribed to relieve acute symptoms due to interaction of histamine at ocular H1 and H2 receptors. While systemic antihistamines often relieve ocular allergic symptoms, patients may experience systemic adverse effects, such as drowsiness and dry mouth.
Can you take steroids for ocular allergies?
As a rule, topical steroids should be prescribed only for a short period of time and for severe cases that do not respond to conventional therapy. Severe forms of ocular allergy may require chronic steroid maintenance therapy to avoid permanent structural damage to the ocular surface and central corneal stroma.

What is the treatment for conjunctivitis?
To examine the diagnosis, management, and treatment of conjunctivitis, including various antibiotics and alternatives to antibiotic use in infectious conjunctivitis and use of antihistamines and mast cell stabilizers in allergic conjunctivitis.
What is the most common cause of conjunctivitis?
Viral conjunctivitis is the most common overall cause of infectious conjunctivitis and usually does not require treatment; the signs and symptoms at presentation are variable. Bacterial conjunctivitis is the second most common cause of infectious conjunctivitis, with most uncomplicated cases resolving in 1 to 2 weeks. Mattering and adherence of the eyelids on waking, lack of itching, and absence of a history of conjunctivitis are the strongest factors associated with bacterial conjunctivitis. Topical antibiotics decrease the duration of bacterial conjunctivitis and allow earlier return to school or work. Conjunctivitis secondary to sexually transmitted diseases such as chlamydia and gonorrhea requires systemic treatment in addition to topical antibiotic therapy. Allergic conjunctivitis is encountered in up to 40% of the population, but only a small proportion of these individuals seek medical help; itching is the most consistent sign in allergic conjunctivitis, and treatment consists of topical antihistamines and mast cell inhibitors.
What percentage of conjunctivitis patients are treated by primary care physicians?
A majority of conjunctivitis patients are initially treated by primary care physicians rather than eye care professionals. Approximately 1% of all primary care office visits in the United States are related to conjunctivitis.5Approximately 70% of all patients with acute conjunctivitis present to primary care and urgent care.6
Why is it important to differentiate conjunctivitis from other eye diseases?
It is important to differentiate conjunctivitis from other sight-threatening eye diseases that have similar clinical presentation and to make appropriate decisions about further testing, treatment, or referral. An algorithmic approach (Figure 2) using a focused ocular history along with a penlight eye examination may be helpful in diagnosis and treatment. Because conjunctivitis and many other ocular diseases can present as “red eye,” the differential diagnosis of red eye and knowledge about the typical features of each disease in this category are important (Table 1).
What is the conjunctiva?
Conjunctiva is a thin, translucent membrane lining the anterior part of the sclera and inside of the eyelids. It has 2 parts, bulbar and palpebral. The bulbar portion begins at the edge of the cornea and covers the visible part of the sclera; the palpebral part lines the inside of the eyelids (Figure 1). Inflammation or infection of the conjunctiva is known as conjunctivitisand is characterized by dilatation of the conjunctival vessels, resulting in hyperemia and edema of the conjunctiva, typically with associated discharge.1
Can conjunctivitis be treated with antibiotics?
However, conjunctivitis caused by gonorrhea or chlamydia and conjunctivitis in contact lens wearers should be treated with antibiotics. Treatment for viral conjunctivitis is supportive. Treatment with antihistamines and mast cell stabilizers alleviates the symptoms of allergic conjunctivitis.
Is conjunctivitis infectious or non-infectious?
Conjunctivitis can be divided into infectious and noninfectious causes. Viruses and bacteria are the most common infectious causes. Noninfectious conjunctivitis includes allergic, toxic, and cicatricial conjunctivitis, as well as inflammation secondary to immune-mediated diseases and neoplastic processes.16The disease can also be classified into acute, hyperacute, and chronic according to the mode of onset and the severity of the clinical response.17Furthermore, it can be either primary or secondary to systemic diseases such as gonorrhea, chlamydia, graft-vs-host disease, and Reiter syndrome, in which case systemic treatment is warranted.16
