Summary
Pterygium inversum unguis, a nail abnormality, occurred in a man after a stroke. This case is unusual due to its association with neurological disorder and asymmetric distribution affecting fingers and toes.
Area of Science:
- Nail disorders
- Dermatology
- Neurology
Background:
- Pterygium inversum unguis is a nail condition characterized by the adherence of the nail bed/hyponychium to the nail plate.
- This adherence obliterates the distal groove, altering nail morphology.
Observation:
- A 50-year-old male patient developed pterygium inversum unguis following a stroke.
- The condition manifested asymmetrically on the right fingers and toes, correlating with right-sided paresis.
Findings:
- The case presents unique features including a link to a neurological disorder.
- Asymmetrical distribution, involvement of both digits and toes, and occurrence in a male patient are notable.
Implications:
- This case highlights a potential association between pterygium inversum unguis and cerebrovascular events.
- Further research may elucidate the pathophysiology linking neurological deficits to nail abnormalities.
- The findings expand the clinical spectrum of pterygium inversum unguis, suggesting broader etiologic considerations.

01:25Glaucoma: 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...
01:28Angle 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...
01:20Muscles of the Eye
The muscles of the eye are sophisticated structures that control eye movement and focus, allowing for the precise and rapid adjustments necessary for vision. The human eye is controlled by ten muscles — six extraocular muscles, three intraocular muscles, and one primary eyelid retractor muscle.
Extraocular Muscles
The six extraocular muscles surround the eyeball and control its movements. They are responsible for a wide range of eye motions, including looking up, down, left, right, and rotating...
