Some topical eye anesthetics are also used in otolaryngology, like for example oxybuprocaine.

Use of topical eye anesthetics in ophthalmology

Topical eye anesthetics are used in ophthalmology in order to numb the surface of the eye (the outermost layers of the cornea and conjunctiva) for the following purposes:

  • In order to perform a contact/applanation tonometry.
  • In order to perform a Schirmer's test (The Schirmer's test is sometimes used with a topical eye anesthetic, sometimes without. The use of a topical eye anesthetic might impede the reliability of the Schirmer's test and should be avoided if possible.).
  • In order to remove small foreign objects from the uppermost layer of the cornea or conjunctiva. The deeper and the larger a foreign object which should be removed lies within the cornea and the more complicated it is to remove it, the more drops of the topical eye anesthetic are necessary to be dropped onto the surface of the eye prior to the removal of the foreign object in order to numb the surface of the eye with enough intensity and duration.

Duration of topical eye anesthesia

The duration of topical eye anesthesia might depend on the type of the topical eye anesthetic and the amount of eye anesthetic being applied, but is usually about half an hour.

Abuse when used for pain relief

When used excessively, topical anesthetics can cause severe and irreversible damage to corneal tissues and even loss of the eye. The abuse of topical anesthetics often creates challenges for correct diagnosis in that it is a relatively uncommon entity that may initially present as a chronic keratitis masquerading as acanthamoeba keratitis or other infectious keratitis. When a keratitis is unresponsive to treatment and associated with strong ocular pain, topical anesthetic abuse should be considered, and a history of psychiatric disorders and other substance abuse have been implicated as important factors in the diagnosis. Because of the potential for abuse, clinicians have been warned about the possibility of theft and advised against prescribing topical anesthetics for therapeutic purposes.

'The Dancer Upstairs' meditates on terrorism

Fox Searchlight Pictures presents a film directed by John Malkovich. Written by Nicholas Shakespeare, based on his novel. Running time: 128 minutes. Rated R (for strong violence and for language). Opening today at the Esquire, Landmark Century and Evanston CineArts.

John Malkovich's "The Dancer Upstairs" was filmed before 9/11, and is based on a novel published in 1997, but has an eerie timeliness in its treatment of a terrorist movement that works as much through fear as though violence.

Filmed in Ecuador, it stars Javier Bardem as Augustin, an inward, troubled man who left the practice of law to join the police force because he wanted to be one step closer to justice. Now he has been assigned to track down a shadowy terrorist named Ezequiel, who is everywhere, and nowhere, and strikes at random to sow fear in the population. His trademark is to leave dead dogs hanging in public view. In China, a dead dog is symbolic of a tyrant executed by the people, we learn.

The movie's story, based on a novel by Nicholas Shakespeare, is inspired by the Shining Path, a terrorist group in Peru. But this is not a docudrama; it is more concerned with noticing the ways in which terrorism takes its real toll on a nation's self-confidence. Ezequiel commits bold and shocking but small-scale public executions, many of helpless civilians in remote districts, but the central government is paralyzed by fear, martial law is declared and the army steps in to Augustin's investigation. The cure may be more damaging than the crime.

Augustin is a very private man. He seems to be happily married and to dote on his daughter, but he is happy to spend long periods away from home and doesn't really seem to focus on his wife's obsession with getting herself an improved nose. He never gives a convincing explanation of why he left the practice of law. His approach to the Ezequiel crimes is largely intuitive; faced with an enemy who works through rumor and legend, he looks more for vibes than clues, and at one point revisits the rural district where his family owned a coffee farm, since confiscated. There he will find--well, whatever he will find.

The movie is contemplative for a police procedural; more like Simenon or Freeling than like Ed McBain. Bardem, who was so demonstrative as the flamboyant writer in "Before Night Falls," now turns as subtle and guarded as--well, as John Malkovich. It is typical that when he falls in love with Yolanda (Laura Morante), his daughter's ballet teacher, both he and she are slow to realize what has happened and reluctant to act on it.

When Ezequiel is finally discovered, it is through a coincidence which I will not reveal here, although his location is made clear to the audience long before Augustin discovers it. I cannot resist, however, quoting one of the film's most cutting lines. We have heard that Ezequiel represents what Marx called "the fourth stage of communism," and when the terrorist is finally dragged into the light of day, Augustin says, "The fourth stage of communism is just a big fat man in a cardigan."

Malkovich has not set out to make a thriller here, so much as a meditation about a man caught in a muddle of his own thinking. By rights, Augustin says at one point, he should be a coffee farmer. The government's confiscation of his family's farm paradoxically did him a favor, by pushing him off the land and into law school, and he is caught between a yearning for the land and a confused desire to make a difference in his society.

As a cop he is trusted by his superiors with great responsibility, but we see him more as a dreamy idealist who doesn't have a firm program for his life and is pushed along by events. He hates the cruelty of Ezequiel but is baffled, as the whole nation is, by Ezequiel's lack of a program, focus or identity. His violent acts function as classical anarchism, seeking the downfall of the state with the hope that a new society will somehow arise from the wreckage.

"The Dancer Upstairs" is elegantly, even languorously, photographed by Jose Luis Alcaine, who doesn't punch into things but regards them, so that we are invited to think about them. That doesn't mean the movie is slow; it moves with a compelling intensity toward its conclusion, which is not a "climax" or a "solution" in the usual police-movie mode, but a small moral victory which Augustin rescues from his general confusion.

When he finally gets to the end of his five-year search for the figure who has distracted and terrorized the country all of that time, his quarry turns out to be a little like the Wizard of Oz. And having pulled aside the curtain, Augustin now has to return to Kansas, or in this case to his wife, who will soon be talking once again about plastic surgery.

Note: The movie, cast with Spanish and South American actors, is entirely in English.
