Surgical removal of a Chalazion from the eye lid

PARASITE REMOVED FROM THE EYEBALL OF A YOUNG N, NOT FOR THE SCREAMISH!Loa Loa worms (also known as the "eye worm") are classified as filarial worms, meaning they thrive in human tissue. The Loa Loa worm is also called the "eye worm" because they often migrate through the eye and surrounding subsurface areas. At one time, prior to the 1920s, loa loa worm infections occurred in the United States. Today, however, they mainly infect people who are native to Sudan, and those who live in or near Central and West Africa's swamps and rain forests.

Loiasis is the infestation of loa loa worms in humans. The larvae are first collected from an infected individual when a mango fly (horsefly) or a deer fly bites the individual, and acquires the larvae. The larvae then progress through the fly's body, finally reaching the feeding tube. They are then transferred to a human host when the fly bites the human. The larvae may remain unnoticed for months or years before becoming an adult, mating, and producing offspring.

Adult female Loa Loa worms can reach a length of 2 1/2 inches while males are approximately half that size. Loa Loa worms can live approximately fifteen years inside their human hosts. They travel continuously through connective and deep tissue, often without the victim experiencing any sensation other than occasional itching.

It is when the worm slows or reaches a sensitive spot that a person will often feel the greatest discomfort. At this point, immune reactions may also include localized redness and a condition called "Calabar" swelling. Skin eruptions and muscle pain may be evident.

When the Loa Loa worm reaches the eye tissue, it can be easily seen and felt within the eyeball for up to an hour. It is usually removed under local anesthesia if the patient is within proximity of a qualified physician. When an adult worm dies, the surrounding tissue may abscess and require excision. Encephalitis can occur if the worm reaches the brain.

After mating, the female will deposit eggs - called microfilariae. These tiny organisms then travel in a worm-like fashion in the bloodstream during daytime hours, when potential host flies are most abundant. They congregate in the lungs at night.

A Loa Loa worm infection is rarely fatal and treatments often cause more life-threatening side effects than the actual infestation, especially if the worms are widespread. The most common treatments are DEC (diethylcarbamazine) and Ivermectin

This video shows management of rupture of the posterior capsule post blunt trauma in a child aged 8. Pre-operative suspicion of PCR was strong because of a flat anterior. So we were careful in our approach from the very beginning. CCC was performed and then dry aspiration of lens matter initiated. Sice vitreous showed, so anterior vitrectomy was done along with systematic removal of the lens matter. An acrysof multi-component lens was implanted into the sulcus and optic captured into the CCC.Outcome was very good.

Cataract eye surgery

This ophthalmology video records a LASIK eye surgery in which difficulties occurred during the procedure. The recording is presented for medical education, showing the operation as it unfolded in the operating room. LASIK is a laser procedure used to correct common vision problems such as short-sightedness.

Ptosis is when the upper eyelid droops over the eye. The eyelid may droop just a little, or so much that it covers the pupil (the black dot at the center of your eye that lets light in). Ptosis can limit or even completely block normal vision. Children and adults can have ptosis. Fortunately, this condition can be treated to improve vision as well as appearance.
