Latanoprost-induced prostaglandin-associated periorbitopathy
1Nassau University Medical Center, East Meadow, Westbury, NY, USA.
Summary
Latanoprost eye drops can cause prostaglandin-associated periorbitopathy (PAP), a condition affecting the skin around the eyes. While less common than with other prostaglandins, awareness and monitoring are crucial for patients.
Area of Science:
- Ophthalmology
- Dermatology
Background:
- Prostaglandin analogs are widely used to treat glaucoma.
- Prostaglandin-associated periorbitopathy (PAP) is a known side effect of some prostaglandin analogs.
Observation:
- This study presents three cases of PAP induced by latanoprost.
- Patients exhibited involution of dermatochalasia, blepharoptosis, deepening of orbital sulci, and flattening of lower eyelid bags.
Findings:
- Latanoprost can cause PAP, characterized by specific periorbital changes.
- The onset of latanoprost-induced PAP appears to have a longer latency period compared to bimatoprost and travoprost.
Implications:
- Ophthalmologists should be aware of latanoprost-induced PAP and monitor patients for its development.
- Unilateral prostaglandin use may lead to noticeable asymmetry in the periorbital region, impacting aesthetics.

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...
Treatment for Pulmonary Arterial Hypertension: Prostacyclin Receptor Agonists
Prostacyclin receptor agonists are a class of therapeutic agents integral to managing pulmonary arterial hypertension (PAH). These drugs operate by mimicking the action of prostaglandin I2, or PGI2, a naturally occurring compound in the body.
These agonists bind to the IPR receptor situated on the plasma membrane of the pulmonary artery smooth muscle cells. This binding triggers a cascade of reactions known as the GS-AC-cAMP-PKA pathway. This pathway results in the relaxation of smooth muscle...

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...
