RESUMO
Background: Due to its ocular microflora, the equine species is predisposed to develop mycotic ulcers which, when notproperly treated, can lead to the formation of a stromal abscess. A stromal abscess occurs through the introduction ofmicroorganisms into the corneal stroma. During re-epithelialization, the foreign body is encapsulated, thus creating abarrier that protects bacteria or fungi from treatment with antimicrobial medication. This framework can end up resultingin blindness due to chronic iridocyclitis, putting the animals vision at risk. The current work aims to report a case of corrective surgery for stromal abscess in a mare with the administration of intraoperative intrastromal fluconazole, in orderto corroborate the effectiveness of the technique.Case: A 9-year-old mare was evaluated, with the complaint that her right eye was closed and yellowish and that she hadalready been treated with intramuscular injectable anti-inflammatory drugs based on flunexin meglumine (Banamine® -50 mg) for 15 days, referring to a possible ulcer in the right eye. Ophthalmic screening resulted in a negative direct reflexand no threat response in the right eye. Examination of the conjunctiva showed congestion and chemosis. Examination ofthe cornea of the right eye was negative for Fluorescein and Green Lissamine tests, and opacity and corneal neovascularization were noted. The final diagnosis was a corneal abscess of probable fungal origin secondary to a keratomycosis. Afterthe consultation, complementary blood and biochemical tests were performed, which showed normal results for the speciesin question, and treatment was started with eye drops based on atropine 1% (Fagra® - 20 mL), ciprofloxacin antimicrobialeye drops (Ciprovet Colirio® - 5 mL), and antifungal eye drops based on ketoconazole...

A healthy 20-year-old woman with myopia had uneventful bilateral laser in situ keratomileusis after which the uncorrected visual acuity was 20/20 in the right eye and 20/30 in the left eye. Fifteen days later, a stromal paraxial lesion was found in the right eye with a corresponding loss of visual acuity, pain, and photophobia. The flap was lifted and the infiltrate scraped for smears. Cultures showed that Rhodococcus globerulus was the infectious agent. Intensive topical antibiotic treatment was applied with good visual results.

A 28-year-old woman had uneventful laser in situ keratomileusis in the right eye. Six days postoperatively, she reported ocular pain and a large corneal stromal infiltrate was observed at the flap interface. A second surgery including lifting and excising the flap and scraping the stromal bed was performed. Topical antibiotics were prescribed. A bacterial culture revealed Streptococcus pneumoniae. The keratitis responded well to topical vancomycin. Twelve days after the second surgery, the stromal infiltrate had regressed, the hypopyon had resolved, and visual acuity was hand movements at 0.5 m.
