A 32-year-old man had photophobia and blurred vision 2 weeks after uneventful laser in situ keratomileusis to correct myopia. He was treated with steroids for suspected diffuse lamellar keratitis, antiherpetics, and antibiotic eyedrops, but the condition worsened and the patient developed further blurred vision, an inflamed eye, and pain. When referred to us, the patient had an extensive corneal ulcer with hypopyon and mycelia were reported in scrapings of the ulcer bed. Nattrassia mangiferae (Hendersonula toruloidea) was cultured from the specimen. The patient was treated with antifungal agents and 2 penetrating keratoplasties. At the last examination, the uncorrected visual acuity was 20/200.

We present a rare case of severe unilateral corneal melt after uneventful phacoemulsification. A 38-year-old woman presented one week after uneventful phacoemulsification cataract surgery complaining of pain and blurred vision in her operated eye. Our differential diagnosis included peripheral ulcerative keratitis, Mooren's ulcer and herpetic keratitis. The patient was started on oral acyclovir and topical steroids. An extensive blood work-up was done to rule out autoimmune diseases. Purified protein derivative test demonstrated 15 mm of erythema. Because the clinical picture was progressing, the patient was started on triple anti-tuberculosis therapy. Despite treatment, the patient was complaining of excruciating eye pain that was relieved only with intramuscular prednisone injections. The corneal melt healed after approximately three months without any other intervention, leaving a 90 per cent thickness loss in its central area. Idiopathic corneal melt after uneventful phacoemulsification is a rare complication, which must be managed in a multidirectional treatment approach to prevent devastating corneal perforation.

Actinobacillus actinomycetemcomitans infection is a rare and easily misdiagnosed ocular disease. In this article, the authors report a chronic, purulent, and difficult-to-treat case of A actinomycetemcomitans keratitis following a glaucoma infiltration surgery.A 56-year-old man with a long-standing history of open-angle glaucoma in both eyes presented with a 12-week history of ocular pain, redness, and blurred vision in his right eye. He underwent a glaucoma infiltration surgery in his right eye 6 months ago. Three months postoperatively, he developed peripheral corneal stromal opacities associated with a white, thin, cystic bleb, and conjunctival injection. These opacities grew despite topical treatment with topical tobramycin, levofloxacin, natamycin, amikacin, and metronidazole eye drops.Multiple corneal scrapings revealed no organisms, and no organisms grew on aerobic, anaerobic, fungal, or mycobacterial cultures. The patient's right eye developed a severe purulent corneal ulcer with a dense hypopyon and required a corneal transplantation. Histopathologic analysis and 16S ribosomalribonucleic acid polymerase chain reaction sequencing revealed A actinomycetemcomitans as the causative organism. Postoperatively, treatment was initiated with topical levofloxacin and cyclosporine, as well as oral levofloxacin and cyclosporine. Graft and host corneal transparency were maintained at the checkup 1 month after surgery.Although it is a rare cause of corneal disease, A actinomycetemcomitans should be suspected in patients with keratitis refractory to topical antibiotic therapy. Delay in diagnosis and appropriate treatment can result in vision loss.

A 17-year-old female patient was referred to Kirana Ophthalmology Unit, Cipto Mangunkusumo Hospital, with a 10-day history of redness and swelling of the eyes, and inability to open them. Other symptoms included pain, blurred vision and excessive yellowish-white discharge from both eyes. There was a history of multiple sexual partners. The patient was assessed with bilateral perforated corneal ulcer due to gonococcal infection, based on the findings of intracellular and extracellular Gram-negative diplococci found on the Gram staining examination. The cornea in both eyes showed perforation with iris prolapse inferiorly. The perforations were treated with temporary periosteal grafts. The grafts remained in place after the surgery. Final uncorrected visual acuity was 6/20 in the right eye and 6/24 in the left eye, a few months after surgery.

A 73-year-old male patient presented with ocular pain, redness, and blurred vision in the left eye, which had been ongoing for more than 2 months. An oval-shaped paracentral corneal ulcer with stromal infiltration and a mild anterior chamber reaction were found. Despite treatment with empiric antibiotics, the lesion progressed and corneal thinning in the middle area was noted. The culture yielded Candida parapsilosis. We therefore prescribed topical 0.2% fluconazole (FCZ) in combination with oral FCZ as an antifungal treatment, following which the stromal infiltration gradually subsided. Complete epithelial-ization was noted on the 8th day after initiating FCZ therapy. There was no recurrent disease in the subsequent 2 years. Our case demonstrates that topical FCZ 0.2% in combination with oral FCZ can successfully treat C. parapsilosis keratitis and result in a good visual outcome.

This study aimed to prospectively evaluate, on a long-term basis, corneal side effects secondary to compassionate administration of epidermal growth factor receptor (EGFR) inhibitor depatuxizumab mafodotin (ABT-414) in patients affected by EGFR-amplified recurrent glioblastoma. Fifteen patients with a median follow-up of 4.3 months after treatment discontinuation were enrolled. Each patient underwent full ophthalmologic examination including in vivo corneal confocal microscopy (CCM). No CTCAE grade 4 toxicity and four (27%) grade 3 toxicities were documented during treatment. Ocular symptoms (blurred vision, eye pain, photophobia) were experienced by all patients, reaching maximal severity after the second ABT-414 infusion, with persistence until treatment discontinuation. During treatment, CCM documented specific changes in the corneal epithelium and in the sub-basal nerve plexus layer fibers of all eyes. The median time of symptoms resolution after treatment discontinuation ranged from 38 days (eye pain) to 53 days (photophobia). The median time of signs resolution ranges from 14 days (corneal ulcer) to 38 days (superficial punctate epitheliopathy, corneal stroma edema and intraepithelial cysts). ABT-414 corneal side effects are detectable in all treated patients. Related symptoms are gradually experienced by all patients during treatment and although reversible, they are characterized by a relative prolonged persistence after treatment discontinuation.
