Intraocular Tuberculosis: A Challenging Case Mimicking Wet Age-Related Macular Degeneration.

An otherwise healthy 72-year-old Chinese patient diagnosed with exudative age-related macular degeneration and decreased vision in left eye was fully investigated. The retrospective analysis of past multimodal imaging revealed bilateral severe choroidal neovascularization and choroiditis associated with a positive tuberculin skin testing and interferon-gamma release assay (QuantiFERON-TB Gold - Cellestis®, Chadstone, VIC, Australia) suggestive of latent ocular tuberculosis. The variable presentation and tests' results interpretation represent the greatest limitations in understanding and treating intraocular TB (IOTB). This may present without any other systemic symptoms, the intraocular tissues are of limited access to biopsies and other tests, including imaging and immunological tests, are of relative value. This case highlights how variable may be the presentation of IOTB, which can be easily misdiagnosed leading to a delayed treatment and worse prognosis.

Suprasellar meningioma presenting with glaucomatous type cupping.

PURPOSE: To describe a case of a suprasellar meningioma compressing the chiasm from below and producing a unilateral fascicular (nasal) visual field defect that mimicked glaucomatous cupping. CASE REPORT: A 78-year-old man presented with painless, progressive, unilateral arcuate visual field defect. He was diagnosed with "normal tension glaucoma" based on an asymmetric cup to disc ratio. Despite treatment with anti-glaucoma drops, the visual field defect progressed. Neurophthalmic evaluation was consistent with a compressive optic neuropathy OD. Brain MRI showed a suprasellar meningioma compressing on the junction of the optic nerve and chiasm from below. CONCLUSION: Although junctional visual field loss (e.g. junctional scotoma and junctional scotoma of Traquair) are well-known presentations of compressive lesions at the optic chiasm, we describe a monocular, ipsilateral compressive superior nasal defect and asymmetric cupping as the presenting sign of a junctional compressive lesion mimicking glaucomatous cupping.

Photodynamic therapy of subfoveal choroidal neovascularization secondary to reticular pattern dystrophy: three-year results of an uncontrolled, prospective case series.

PURPOSE: To investigate the effects of photodynamic therapy (PDT) on subfoveal choroidal neovascularization (CNV) secondary to reticular pattern dystrophy (RPD) of the retinal pigment epithelium. DESIGN: Open-label, prospective, interventional case series. METHODS: Thirteen eyes diagnosed with subfoveal CNV associated with RPD were considered. Complete ophthalmic examinations were performed at baseline and thereafter at three-month intervals for three years. Primary outcome measure was the number of eyes with <15 letters loss (approximately <3 lines) at 12, 24, and 36 months, compared with baseline. Secondary outcome measures included CNV progression and number of PDT sessions. RESULTS: Seven eyes showed a decrease in best-corrected visual acuity of at least three lines at three-year examination. Each eye received a median number of treatments of two, zero, and zero in years one, two, and three, respectively. CONCLUSIONS: PDT does not appear to guarantee long-term vision stabilization in RPD-related subfoveal CNV, and alternative therapies should be investigated.

Polymicrobial keratomycosis in a three-year-old child.

PURPOSE: To describe a previously unreported case of polymicrobial mycotic keratitis caused by an association between Candida lusitaniae, C. parapsilosis, and Geotrichum candidum. METHODS: A three-year-old child with an antecedent trauma with vegetable matter and a prolonged use of corticosteroid eyedrops developed fungal keratitis. RESULTS: The isolates of the corneal scraping using Sabaraud dextrose agar grew C. lusitaniae, C. parapsilosis, and G. candidum. After topical 0.2% and systemic fluconazole treatment, the corneal lesion resolved with no recurrence. CONCLUSIONS: Corneal trauma with vegetables and the indiscriminate use of corticosteroids are important risk factors for mycotic keratitis. A combination of topical 0.2% and systemic fluconazole therapy was effective in the treatment of this mycotic association. This is the first report of fungal keratitis caused by C. lusitaniae and G. candidum.
