Contact dermatitis to topical drugs for glaucoma
1Department of Internal Medicine, Lakeside Hospital, Metairie, LA 7001, USA.
Summary
Topical glaucoma drugs can cause allergic contact dermatitis. Ten agents, including beta-blockers and pilocarpine, are implicated, with potential for cross-reactivity and rare systemic reactions.
Area of Science:
- Ophthalmology
- Dermatology
- Pharmacology
Background:
- Glaucoma treatment often involves topical medications.
- Adverse reactions to ophthalmic drugs can impact patient adherence and outcomes.
- Contact dermatitis is a known side effect of some topical agents.
Purpose of the Study:
- To identify agents causing contact dermatitis in topical glaucoma medications.
- To review documented cases of patch testing, cross-sensitization, and reactivity.
- To note systemic reactions associated with these topical treatments.
Main Methods:
- Literature review of studies on topical glaucoma medications.
- Identification of drugs associated with contact dermatitis.
- Analysis of reported patch testing, cross-reactivity, and systemic reactions.
Main Results:
- Ten agents identified as causing contact dermatitis.
- Includes beta-blockers (e.g., timolol), a carbonic anhydrase inhibitor (dorzolamide), a parasympathomimetic (pilocarpine), and sympathomimetics (dipivefrin, apraclonidine).
- Patch testing, cross-sensitization, and systemic reactions were documented.
Conclusions:
- Several classes of topical glaucoma drugs can induce contact dermatitis.
- Awareness of these agents is crucial for diagnosis and management.
- Further investigation into cross-reactivity and systemic effects may be warranted.

Glaucoma: Overview
Glaucoma is an eye condition characterized by increased intraocular pressure that damages the retina and optic nerve, leading to irreversible blindness if left untreated. The human eye has various components, including the cornea, iris, pupil, lens, and optic nerve. Aqueous humor is secreted by the epithelium of the ciliary body in the posterior chamber and flows through the trabecular meshwork and canal of Schlemm, maintaining normal intraocular pressure. The trabecular meshwork and the canal...
Open Angle Glaucoma: Treatment
In open-angle glaucoma, the iridocorneal angle remains open, but the trabecular meshwork becomes stiff, slowing down the outflow of aqueous humor. This causes a buildup of aqueous humor in the anterior chamber, leading to a sudden increase in intraocular pressure. The treatment for open-angle glaucoma focuses on reducing the elevated intraocular pressure by either decreasing the secretion of aqueous humor or increasing its outflow.

Angle Closure Glaucoma: Treatment
Angle-closure glaucoma, or closed-angle glaucoma, is an eye condition where the iris bulges out and blocks the iridocorneal angle, resulting in a buildup of aqueous humor and increased intraocular pressure. Immediate medical attention is necessary due to the sudden onset of symptoms. The treatment for angle-closure glaucoma includes short-term and long-term approaches. Short-term treatment involves using eye drops like pilocarpine to lower intraocular pressure by increasing aqueous humor...
Drug Delivery: Miscellaneous Routes
Drug delivery methods like oral inhalation, nasal sprays, transdermal patches, eye drops, intravitreal injection, and rectal administration provide localized effects with reduced toxicity.
Oral inhalation and nasal sprays swiftly transfer drugs across the respiratory epithelium's mucosal layer. Inhaled glucocorticoids and bronchodilators directly target lung conditions such as asthma, while fluticasone nasal spray mitigates allergic rhinitis.
Transdermal patches transport drugs through the...

Ophthalmic Drug Delivery Systems
Ophthalmic drug delivery faces major limitations due to poor absorption across the corneal membrane. This process is primarily driven by diffusion and is influenced by two main factors: the physicochemical properties of the drug and tear drainage. Most ophthalmic drugs, such as pilocarpine, epinephrine, atropine, and local anesthetics, are weak bases. They are typically formulated at an acidic pH to enhance chemical stability. However, this leads to high ionization, reducing their ability to...
Drug Toxicity: Allergic Reactions
Drug-related allergies are immune-mediated responses triggered by the administration of pharmacological agents. These hypersensitivity reactions are classified based on the immune mechanisms involved. The four primary types—Type I, II, III, and IV—are mediated by different immunological pathways and exhibit distinct clinical manifestations.Type I Hypersensitivity/ IgE-Mediated Reactions: Immunoglobulin E (IgE) immediately mediates Type I hypersensitivity reactions. Upon initial exposure to a...
