Paul H Phillips, Claire A Sheldon
Idiopathic intracranial hypertension, otherwise known as primary pseudotumor cerebri syndrome (PTCS), most frequently occurs in obese women of childbearing age. However, children may be affected as well. This review will address recent findings regarding demographics, diagnosis, and treatment of pediatric PTCS. Prepubertal children with primary PTCS have an equal sex distribution and less frequent obesity compared with adult patients. However, female gender and obesity are risk factors for primary PTCS in postpubertal children...

Megan E Cavet, Heleen H DeCory
Latanoprostene bunod (LBN) is a topical ophthalmic therapeutic for the reduction of intraocular pressure (IOP) in patients with open-angle glaucoma or ocular hypertension (OHT). LBN is composed of latanoprost acid (LA) linked to a nitric oxide (NO)-donating moiety and is the first NO-releasing prostaglandin analog to be submitted for marketing authorization in the United States. The role of latanoprost in increasing uveoscleral outflow of aqueous humor (AqH) is well established. Herein, we review findings from nonclinical studies, which evaluated the role of NO in the IOP-lowering efficacy of LBN...

Glaucoma is an eye-related disease accompanied by highly elevated intraocular pressure (IOP), which causes damage to the optic nerve and results in vision loss and even blindness. Although the treatment of glaucoma with eye drops may reduce the IOP, eye drops have some limitations, such as poor patient compliance and short duration. To develop drug carriers that facilitate the sustained and long-term release of drugs for glaucoma therapy, we synthesized poly(ε-caprolactone) nanoparticles (PCL NPs) capable of loading pilocarpine, a widely used drug for the treatment of dry eye and glaucoma...

Acute ocular hypertension (AOH) frequently compromises corneal endothelial cell (CEC) function in clinical practice. This type of stress induces corneal oedema and a decrease in the corneal endothelial cell density (ECD). The anterior chamber of the right eye of Sprague-Dawley rats was irrigated with Balanced Salt Solution (BSS) for two hours, and the left eye served as a control to determine the time-dependent effects of AOH on endothelial cell morphology and function. The average intraocular pressure (IOP) increased to 82...

Diabetic retinopathy (DR) is the most feared ocular manifestation of diabetes. DR is characterized by progressive retinal damage that may eventually result in blindness. Clinically, this blindness is caused by progressive damage to the retinal microvasculature, which leads to ischemia, retinal swelling, and neovascularization. Retinopathy is associated with both type 1 and type 2 diabetes, with DR being the leading cause of new onset blindness in United States adults. Despite this strong association with diabetes, it must be noted that the development of retinopathy lesions is multifactorial and may occur in individuals without an established history of diabetes...

Glaucoma is a leading cause of irreversible blindness worldwide. The reduction of intraocular pressure has been well established as an effective treatment to prevent both the development and the progression of all forms of glaucoma. Bimatoprost 0.03% ophthalmic solution, introduced in 2001, is a synthetic prostamide with the unique mechanism of improving both uveoscleral and trabecular outflow. Comparative studies with other pharmacotherapies have shown favorable results for bimatoprost as a potent ocular hypotensive agent that is generally well tolerated...
