Summary
A case of orbital myiasis in an elderly farmer, caused by Lucilia sericata (green bottle fly) larvae, was successfully treated. Maggot removal and antibiotic dressing led to complete ulcer healing within two weeks.
Area of Science:
- Ophthalmology
- Medical Entomology
Background:
- Orbital myiasis is a rare condition involving maggot infestation of the eye socket.
- Untreated ocular trauma can predispose individuals to such infestations.
Observation:
- An 80-year-old farmer presented with a large, maggot-infested ulcer on the right upper eyelid.
- The patient had a history of untreated traumatic laceration to the affected eyelid.
- The contralateral eye was phthisical (shrunken and non-functional).
Findings:
- Mechanical removal of maggots, aided by turpentine application, was performed.
- Microbiological analysis identified the larvae as Lucilia sericata (green bottle fly).
- The ulcer healed completely within two weeks with regular antibiotic dressing and maggot removal.
Implications:
- This case highlights the importance of prompt management of ocular trauma to prevent complications like myiasis.
- Early diagnosis and treatment, including maggot debridement, are crucial for favorable outcomes in orbital myiasis.
- Further research into prevention and treatment strategies for this uncommon condition is warranted.

75
The human eye has a specialized microbiota that reflects its unique anatomical and immunological environment. This low-biomass microbial community predominantly colonizes the conjunctiva and eyelid margins, playing a vital role in ocular surface homeostasis and defense. Despite its proximity to the richly colonized facial skin, the ocular surface maintains a distinct microbial profile due to continuous mechanical and biochemical defense mechanisms.The conjunctival surface hosts fewer microbial...

1.7K
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...

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...

Arboviral encephalitis refers to brain inflammation caused by arthropod-borne viruses, particularly those transmitted through mosquito vectors. Among these, West Nile virus (WNV), a member of the Flaviviridae family, is a significant public health concern. WNV is an enveloped, positive-sense, single-stranded RNA virus. Human infection typically begins when an infected mosquito introduces the virus into the dermis during feeding. The primary transmission cycle involves birds as amplifying hosts...
