New technology to visualize axonal fiber bundles on the retina for early diagnosis of optic neuropathies
A research team led by the Department of Ophthalmology, School of Clinical Medicine, LKS Faculty of Medicine of The University of Hong Kong (HKUMed), with collaborators from the Faculty of Medicine of The Chinese University of Hong Kong (CU Medicine) and local and international partners, have developed a new technology ROTA (Retinal nerve fiber layer Optical Texture Analysis) to unveil the optical texture and trajectories of the axonal fiber bundles on the retina. ROTA outperforms the current clinical standards, attaining 15.0% to 28.4% higher in sensitivity in detecting early optic nerve damage in glaucoma—the leading cause of irreversible blindness. The research has been published in Nature Biomedical Engineering.

Lecture: How to Interpret OCT Findings in the Diagnostic Evaluation of Glaucoma
Optical coherence tomography (OCT) has become an indispensable tool in the diagnostic evaluation of glaucoma. However, deciding what regions (e.g., optic disc region vs. macula) and what parameters (e.g., retinal nerve fiber layer (RNFL) thickness vs. ganglion cell inner plexiform layer (GCIPL) thickness vs. neuroretinal rim width) to measure can often be confusing. False positives and false negatives in OCT reports are common. This webinar will walk through examples from different OCT models and elaborate correct interpretation of OCT findings to aid diagnosis and monitoring of glaucoma.

Uncovering the trajectories of axonal fiber bundles to augment the diagnostic precision to detect retinal nerve fiber layer defects in glaucoma
Reliable detection of retinal nerve fiber layer (RNFL) defects is challenging in clinical practice. We developed RNFL Optical Texture Analysis (ROTA) to unveil the trajectories of individual axonal fiber bundles and discern RNFL defects in glaucoma with high sensitivity and specificity.

How Susceptible is the Conjunctiva to COVID-19?
Researchers at the University of Hong Kong have found that SARS-CoV-2, the cause of COVID-19, replicates in the conjunctiva to a greater extent than the severe acute respiratory syndrome coronavirus that triggered the notorious SARS epidemic (SARS-CoV) that afflicted 26 countries with more than 8,000 cases in 2003.[1] In fact, one of the researchers, in an interview with the South China Morning Post, says SARS-CoV-2 is much more efficient in infecting the human conjunctiva and the upper respiratory airways than SARS, with virus level about 80 to 100 times higher, which might explain its high transmissibility. However, the researchers and a leading corneal specialist in the United States, emphasize that the findings don’t necessarily translate to an increased risk of transmission of COVID-19 through the conjunctiva.
