Maria Rebecca Ballestra: absence between Nature and Human Being in Echoes of the Void.
No full textMaria Rebecca Ballestra (1974–2020) was an Italian artist whose work focused on ecology, climate change, and the Anthropocene. In Echoes of the Void (2015–2020), one of her latest projects, the absence of humans is central: photographs of the world’s largest deserts convey a sense of emptiness and highlight Nature’s persistence. The work challenges conventional perceptions of deserts as empty, isolated spaces, instead presenting them as sites that disorient, test, and accompany the individual. This paper examines how her work explores the dynamics between Nature and Humanity
Moorfield regression analysis versus retinal nerve fiber layer in glaucoma and ocular hypertension
No full textPurpose: To evaluate the agreement
between Moorfield Regression
Analysis (MRA) and peripapillary
retinal nerve fibers layer thickness.
Methods: 54 eyes with normal VF
and 18 with early VF damage were
classified as ocular hypertension or
early primary open angle glaucoma
(POAG) and were included in the
study: All the subjects performed
achromatic 30° visual field (VF) by
Octopus Program G1X dynamic
strategy and were imaged by HRT 3
and I-Vue OCT. Sectorial and global
MRA and OCT parameters were
used for the analysis. Kappa statistic
was used to assess the agreement
between methods.
Results: A significant agreement
between I-Vue OCT and MRA a
good agreement was shown in the
supero-nasal (κ 0.656) and nasal
(κ 0.627) quadrants followed by the
supero-temporal (κ 0.602) and inferotemporal
(κ 0.586) sectors in all the
eyes studied.
Conclusion: Our results suggest that
the measurements of the ganglion
cells by HRT 3 and I-Vue OCT are not
interchangeable

No full textReduction in Retinal Nerve Fiber Layer Thickness in Young Adults with Autism Spectrum Disorders
No full textRecent years have seen an increase in the use of retinal nerve fiber layer (RNFL) evaluation as an easy-to-use, reproducible, proxy-measure of brain structural abnormalities. Here, we evaluated RNFL thickness in a group of subjects with high functioning autism (HFA) or with Asperger Syndrome (AS) to its potential as a tool to study autism pathophysiology. All subjects underwent high-resolution spectral domain optical coherence tomography to evaluate RNFL thickness. HFA subjects presented with reduced global RNFL thickness compared both to AS subjects and controls. AS subjects showed a reduced nasal quadrant RNFL thickness compared to controls. Verbal-IQ/performance-IQ discrepancy correlated with RNFL thickness. Our data suggest that RNFL evaluation could help in the development of biological markers of autism pathophysiology

Optical coherence tomography and infrared images of astrocytic hamartomas not revealed by funduscopy in tuberous sclerosis complex
No full textPURPOSE:To detect, describe, and classify the morphologic characteristics of astrocytic hamartomas in tuberous sclerosis complex, using both spectral-domain optical coherence tomography (OCT) and infrared images.
METHODS:
Ten subjects (20 eyes) with tuberous sclerosis complex underwent a complete ophthalmologic examination and multimodality imaging with spectral-domain OCT and infrared images. The imaging protocol included a 30°scan angle of the posterior pole and of the four quadrants. Line scans, detail, raster, and posterior pole patterns were used. The identified astrocytic hamartomas were described and characterized qualitatively and quantitatively.
RESULTS:
Forty-four hamartomas were detected in 8 patients. In five cases, lesions were bilateral. Thirty of these hamartomas had not been revealed by previous ophthalmoscopy. Through multimodality imaging, it was possible to define multiple lesions with characteristic optical reflective qualities. All the 44 hamartomas were measured and morphologically characterized in terms of the type of tumor, retinal and/or vitreous involvement, calcifications, and posterior optical shadowing.
CONCLUSION:
The combined imaging with spectral-domain OCT and infrared images improves the detection of hamartomas if compared with the spectral-domain OCT technique alone. Moreover, a new subtype of hamartoma is proposed to complete a previous classification based on OCT
