Two rare cases of Acremonium acute endophthalmitis after cataract surgery in a tertiary care hospital.

This report describes two cases of Acremonium sp. endophthalmitis, occurring in two patients who underwent cataract surgery on the same day in the same operating room of our hospital ophthalmology clinic. Diagnosis of fungal endophthalmitis was established by the repeated isolation of the same fungal agent from vitreous washing, acqueous fluid and intraocular lens samples and by its identification on the basis of morphological and molecular features. The cases reported in this study emphasize the need for clinical microbiology laboratories to be prepared to face the diagnosis of uncommon infectious diseases such as exogenous fungal endophthalmitis by Acremonium, and to enhance the awareness of surgeons and clinicians of this occurrence.

Corneal thickness mapping by 3D swept-source anterior segment optical coherence tomography.

PURPOSE: To assess accuracy and repeatability of central corneal thickness (CCT) measurements obtained by swept-source anterior segment optical coherence tomography (AS-OCT), spectral-domain retinal OCT with corneal module and ultrasound pachymetry (USP), and to assess repeatability of pachymetric mapping with AS-OCT. METHODS: 50 healthy volunteers were recruited. A single, experienced operator analysed the right eye of each participant twice in the same session with AS-OCT ('corneal map' routine), retinal OCT and USP. CCT measurements were compared using repeated-measures analysis of variance, Bonferroni test, Pearson correlation and Bland-Altman plots. Repeatability of thickness maps and CCT measurements were assessed using Alpha of Cronbach, intraclass correlation coefficient (ICC) and coefficient of repeatability. RESULTS: Mean CCT±SD was 540±28.9 µm for AS-OCT, 544±29.5 µm for retinal OCT and 549.3±31.7 µm for USP; the differences were statistically significant (p<0.01). CCT measurements obtained with the three instruments were highly correlated: r was 0.965 for AS-OCT/USP, 0.962 for retinal OCT/USP and 0.984 for AS-OCT/retinal OCT comparison. The repeatability of CCT measurements was higher for AS-OCT than for the other devices (p<0.001). Repeatability of pachymetric maps was excellent (ICC=0.999). CONCLUSIONS: Pachymetric maps by swept-source AS-OCT showed excellent repeatability. CCT measurements obtained by AS-OCT, USP and retinal OCT were highly correlated although not identical.
