RESUMEN
Aspergilloma is a fungal ball that usually forms in a preformed stationary cavity, mostly in lung and paranasal sinuses. We report a rare case of primary orbital Aspergilloma following exenteration for an invasive ocular surface squamous neoplasia, clinically mimicking a recurrence of the tumor. The fungal ball showed the presence of conidiophores with a globular head and a complete row of uni and biserrate phialides, suggestive of Aspergillus flavus species. The exposure to air in the orbit, possibly promoted the formation of conidiophores, which are normally seen when the organism is located in air cavities.

Botulinum toxin chemodenervation has evolved greatly over the past 30 years since its introduction in the 1970s for the management of strabismus. Among ophthalmic plastic surgeons, botulinum toxins are often used as the first line treatment for facial dystonias. These toxins are also efficacious for the temporary management of various other conditions including keratopathies (through so called chemo-tarsorraphy), upper eyelid retraction, orbicularis overaction-induced lower eyelid entropion, gustatory epiphora, Frey's syndrome, and dynamic facial rhytids such as lateral canthal wrinkles (crow's feet), glabellar creases and horizontal forehead lines. This article describes the pharmacology, reconstitution techniques and common current applications of botulinum toxins in ophthalmic plastic surgery.

Precautions to prevent spread of infection through tonometers and gonioscopes are described in this article. Tonometers and gonioscopes should not be used in the presence of clinically manifest conjunctivitis and keratitis. The Schiotz tonometer should be dipped in a 1:1000 merthiolate solution, and rinsed in saline/distilled water prior to use. The Goldmann applanation prism tip can be wiped with gauze soaked in 70% isopropyl alcohol and then dried before use. Gonioscopes should be cleaned in running water, wiped with gauze soaked in 70% isopropyl alcohol, and then dried before use. Koeppes and goniotomy lenses can be sterilized with ethylene oxide, prior to use in surgery.
