Summary
Epiphora (watery eye) can result from nasolacrimal duct obstruction caused by cosmetic particles. Histopathology is crucial to distinguish cosmetic-induced inflammation from melanoma.
Area of Science:
- Ophthalmology
- Pathology
Background:
- Epiphora, or watery eye, is a common condition.
- Nasolacrimal duct obstruction (NLDO) is a frequent cause of epiphora.
- Distinguishing between innate melanocytic processes and exogenous causes of NLDO is clinically important.
Purpose of the Study:
- To present a case of epiphora caused by cosmetic-induced foreign bodies in the nasolacrimal duct.
- To highlight the importance of histopathological examination in diagnosing the cause of NLDO.
Main Methods:
- Case report of a woman presenting with epiphora.
- Histopathological analysis of tissue from the nasolacrimal duct.
- Identification of pigmented, birefringent foreign bodies consistent with cosmetics.
Main Results:
- Complete nasolacrimal duct obstruction was diagnosed.
- Granulomatous inflammation was observed around foreign bodies.
- Foreign bodies were identified as consistent with cosmetic particles.
Conclusions:
- Cosmetic particles can cause granulomatous inflammation leading to nasolacrimal duct obstruction and epiphora.
- Patient history and histopathology are essential for accurate diagnosis, differentiating cosmetic-induced issues from conditions like melanoma.

01:25Glaucoma: Overview
740
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
665
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...

6.5K
At the molecular level, visual signals trigger transformations in photopigment molecules, resulting in changes in the photoreceptor cell's membrane potential. The photon's energy level is denoted by its wavelength, with each specific wavelength of visible light associated with a distinct color. The spectral range of visible light, classified as electromagnetic radiation, spans from 380 to 720 nm. Electromagnetic radiation wavelengths exceeding 720 nm fall under the infrared category,...
