Leukotrienes are responsible for recruiting other blood cells, such as polymorphonucleocytes and eosinophils, to the site of irritation. Polymorphonucleocytes are white blood cells, which play a key role in infection and inflammation. They release enzymes to kill the offending organism. Eosinophils play a role in the late stages of allergy. Both of these cells perform a needed function, but can be damaging to normal surrounding tissue.

Papillae on the lids are aggregations of eosinophils. Subepithelial infiltrates in the cornea are accumulations of polymorphonucleocytes. Anterior chamber cells in iritis are the result of polymorphonucleocytes spilling into the aqueous due to increased vasopermeability.

Steroids vs. By blocking the cyclo-oxygenase arm, steroids decrease vasopermeability as well as redness, edema, pain and uveoscleral outflow. Steroids also block the lipoxygenase arm, keeping polymorphonucleocytes and other blood cells sequestered from the site of inflammation. But unlike steroids, they do not possess the effectiveness of sequestering blood cells.

NSAIDs are useful in controlling pain and limiting inflammation, but they have not been shown to be clearly effective in treating uveitis, and they play no role in corneal graft rejection. Treatment with NSAIDs can be an advantage if youre trying to reduce pain without reducing the bodys immune system i. However, if youre trying to prevent tissue damage i.

Potency and Penetration Corticosteroids differ in their inherent anti-inflammatory ability. Their potency hinges on their penetration. To get to the anterior chamber of the eye, topical ocular preparations must pass through the lipid-rich epithelium of the cornea, then the water-laden stroma, and finally through the mainly lipid endothelium. For a steroid to effectively penetrate the cornea, it must be both lipophilic and hydrophilic.

Such preparations are termed biphasic. The chemical base to which a topical steroid is attached will determine its ability to penetrate the anterior chamber. In the normal eye, an acetate base penetrates the best, followed by alcohols, and then phosphates.

Removal of the lipid-rich epithelium such as a corneal abrasion or corneal ulcer will allow a phosphate base to reach a much higher concentration. Also, inflammation can break down the lipid barriers, allowing for more penetration of phosphate. Solution vs. Suspension vs. Ointment The base of the corticosteroid also helps determine if the drug can be produced as a solution or suspension.

Phosphate bases, which are water-soluble, are marketed as solutions. Acetates are prepared as suspensions. The advantage of a solution: It doesnt require shaking prior to instillation to deliver a uniform dose of active ingredient to the eye. The advantage of suspension: Small particles of the drug persist in the cul-de-sac, resulting in prolonged contact time and higher penetration.

Given this comparison, one would think ointments would be the ultimate delivery system. However, petrolatum fails to release the drug rapidly to the precorneal tear film, so despite a prolonged contact time, less drug is available than a suspension for penetration. Topical Steroid Side Effects The side effects of these drugs have sometimes been exaggerated and misunderstood.

For the treatment of many ocular conditions, short-term use of steroids has minimal risks and significant therapeutic benefits. Side effects from long-term use, however, can potentially outweigh the benefits. Although much safer than their systemic counterparts, topical steroids can produce many side effects, notably: Elevated intraocular pressure. Perhaps the most worrisome and misunderstood complication of topical steroids is elevated IOP.

This side effect is more common with topical therapy than with oral or parenteral. With proper knowledge of the steroid response, we can anticipate elevated IOP and effectively control it. Steroid-induced elevated IOP rarely occurs within the first two weeks of treatment. Withdrawal of the steroid usually results in IOP returning to baseline in two to four weeks.

It is more common in patients more than 40 years of age, diabetics, high myopes and previously diagnosed open-angle glaucoma patients. Accumulations of glycosaminogylcans in the trabecular meshwork, inhibition of prostaglandins that reduce IOP, and heredity have all been implicated. The incidence of IOP response varies with the drug being administered.

Among the traditional topical steroids, IOP increases occur most frequently with dexamethasone-based agents and least frequently with the fluorometholones. Perhaps less serious than steroid-induced glaucoma is steroid-induced cataract. This is because untreated ocular inflammation also induces cataract formation which, unlike elevated IOP or glaucoma, can be wholly eliminated by surgery.

Other than its location, there are no other clinical characteristics to differentiate a steroid-induced cataract from other PSCs. The exact incidence varies widely in studies and is difficult to ascertain, given that intraocular inflammation itself can cause cataracts.

The cause of steroid-induced cataracts may involve many mechanisms. The suggested etiologies: binding of the steroid molecule to lens protein; inhibition of the lens pump; and elevated glucose in the aqueous. Mydriasis, ptosis, inhibition of corneal epithelial or stromal healing, punctate staining, and corneal-scleral melting are all less common side effects of steroids.

Reactivation of herpes simplex keratitis in previously infected patients has also been attributed to topical steroids. The Drugs Prednisolones. As with all suspensions, prednisolone acetate requires shaking before use to equally distribute the particles, which tend to settle to the bottom of the bottle. Prednisolone acetate is also available in a much weaker 0. The phosphate base will not provide as much penetration as prednisolone acetate; however, it is formulated as a solution and does not require shaking.

Prednisolone sodium phosphate is most appropriate for moderate inflammation. Topical dexamethasone preparations are potent agents for surface inflammation, but they do not penetrate well for intraocular inflammation.

They also have the highest propensity to increase IOP. TobraDex suspension and ointment Alcon are popular combinations of dexamethasone and tobramycin an aminoglycoside antibiotic in a single preparation. Fluorometholone has traditionally been considered the best of class for avoiding the steroid-induced IOP response, most likely because of its poor corneal penetration. Fluorometholone alcohol 0. Its low propensity for side effects also makes it a good choice for long-term therapy.

Fluorometholone is one of the few steroids available in an ophthalmic ointment. Fluorometholone is also available combined with an acetate base Flarex, Alcon, and eFlone, Novartis for better penetration. Newer Drugs A recent trend in anti-inflammatory therapy is the development of soft steroids. A soft drug is a biologically active compound with a predictable inactivation to a nontoxic substance after achieving its therapeutic role.

A weaker version of loteprednol in a 0. With knowledge of the concepts of inflammation and the fundamentals of corticosteroid therapy, these agents can be used safely and effectively for treating a number of ocular conditions in the optometric office. Cakanac is in private practice in Pittsburgh and is a clinical instructor in the Department of Ophthalmology at the University of Pittsburgh School of Medicine.

Accessed May 30, Prolonged use of corticosteroids may result in glaucoma with damage to the optic nerve, defects in visual acuity and fields of vision. If this product is used for 10 days or longer, IOP should be monitored. Use of corticosteroids may result in posterior subcapsular cataract formation and may delay healing and increase the incidence of bleb formation after cataract surgery.

In those diseases causing thinning of the cornea or sclera, perforations have been known to occur with the use of topical steroids. The enzyme phospholipase A 2 converts phospholipids into arachidonic acid. Arachidonic acid may then follow two chemical pathways: Cyclo-oxygenase. Arachidonic acid may be converted to prostaglandins by cyclo-oxygenase.

Prostaglandins mediate the pain response and cause increased vasopermeability. As blood leaks into surrounding tissues from the increased permeability, the symptoms of redness, swelling, heat and pain are produced. Arachidonic acid may also follow another pathway and be converted to leukotrienes by lipoxygenase.

Leukotrienes are responsible for recruiting other blood cells, such as polymorphonucleocytes and eosinophils, to the site of irritation. Polymorphonucleocytes are white blood cells, which play a key role in infection and inflammation. They release enzymes to kill the offending organism.
