Summary
Mascara particles can cause chronic inflammation and secondary nasolacrimal duct obstruction, requiring dacryocystorhinostomy (DCR). This case highlights mascara as a potential cause of nasolacrimal duct obstruction, even after DCR surgery.
Area of Science:
- Ophthalmology
- Histopathology
Background:
- Nasolacrimal duct obstruction (NLDO) can cause epiphora and ocular discharge.
- Mascara-induced conjunctival pigmentation is known, but NLDO from mascara is rarely reported.

Angle Closure Glaucoma: Treatment
919
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...

Suctioning the Nasopharyngeal Airway

Nasopharyngeal suctioning is a procedure to remove secretions from the upper part of the respiratory tract that the patient cannot clear independently. It helps maintain airway patency and prevents complications such as aspiration pneumonia.

Accessory Structures of the Eye

Optical perception, or vision, is an extraordinary sense dependent on converting light signals received via the ocular organs. These organs, known as eyes, are securely positioned within the bony cavities of the skull, called orbits. The orbits serve a dual purpose: a protective shield for the ocular globes and a stable attachment point for the soft ocular tissues. The eye's external protective mechanisms include the eyelids, which are edged with lashes that act as a barrier against foreign...
