Insights

Leprosy (Hansen disease) can cause late-onset eye complications like nasolacrimal duct obstruction. This case shows granulomatous inflammation in the lacrimal sac, a rare sequela of treated Mycobacterium leprae infection.

Area of Science:

  • Ophthalmology
  • Infectious Diseases
  • Pathology

Background:

  • Leprosy, or Hansen disease, is caused by Mycobacterium leprae and can affect the skin, nerves, and eyes.
  • While treated, leprosy can have long-term sequelae, including ocular complications.

Purpose of the Study:

  • To report a case of epiphora due to chronic nasolacrimal duct obstruction as a late complication of treated tuberculoid leprosy.
  • To describe the pathological findings in the lacrimal sac.

Main Methods:

  • Endoscopic dacryocystorhinostomy (DCR) was performed.
  • Histopathological examination of the lacrimal sac specimen was conducted.
  • Fite staining was used to identify bacterial structures.

Main Results:

  • The patient presented with epiphora four years post-treatment for leprosy.
  • Dacryocystitis with granulomatous inflammation and bacterial structures was found in the lacrimal sac.
  • Pathology revealed non-necrotizing granulomas consistent with sequelae of M. leprae infection.

Conclusions:

  • Chronic nasolacrimal duct obstruction can be a delayed manifestation of treated leprosy.
  • Granulomatous inflammation in the lacrimal sac is a potential sequela of M. leprae infection.
  • Surgical intervention (DCR) can effectively manage this complication.

Glaucoma: Overview01:25

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...

Angle Closure Glaucoma: Treatment01:28

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...

Lysosomal Hydrolases01:22

Lysosomal Hydrolases

Lysosomes are the site for the degradation of macromolecules and biological polymers released during membrane trafficking events such as secretory, endocytic, autophagic, and phagocytic pathways. The membrane-enclosed area of the lysosome, called the lumen, contains hydrolytic enzymes active in an acidic environment. These acid hydrolases are functional at a pH between 4.5 and 5 and are involved in cellular processes such as cell signaling, energy metabolism, restoration of the plasma membrane,...
