Corneal anterior segment imaging has emerged as a screening tool for refractive surgery, cataract and glaucoma. In this article, the authors discuss their recent study that identified a set of normative data to correct for sources of bias in pre-surgery screening.
New lenses show promise for sustained glaucoma treatmentFebruary 26th 2014
Researchers at University of California, Los Angeles, USA, have developed a new delivery system for treating patients with glaucoma. They have combined nanodiamonds - a by-product of conventional mining and refining processes - with timolol maleate into contact lenses that deliver sustained doses.
Integrated laser platform receives CE Mark approvalFebruary 7th 2014
The Optimis Fusion integrated laser platform from Quantel Medical has received CE Mark approval. The system is a combination of advanced selective laser trabeculoplasty photoregeneration therapy with traditional YAG photodisruption treatment for treating both cataract and glaucoma.
Retinal oxygen metabolism differs in glaucoma patientsFebruary 5th 2014
Patients with advanced glaucoma have higher oxygen saturation in venules and lower arteriovenous difference in oxygen saturation compared with healthy individuals. The decrease in arteriovenous difference in patients with severe glaucoma may be related to lower oxygen consumption secondary to neuropathy
HEP could be important in diagnosis and monitoring of glaucomaNovember 21st 2013
Heidelberg edge perimetry (HEP) may have role in the early detection and assessment of functional damage cause by glaucoma, according to the authors of a case report presented online at PubMed via Case Reports in Ophthalmology. Further, HEP testing may potentially have advantages over standard automated perimetry (SAP), currently the gold standard for visual function testing.
Laser speckle flowgraphy may be useful in identifying eyes with normal-tension glaucomaNovember 8th 2013
Waveform changes in optic nerve head (ONH) blood flow as measured by laser speckle flowgraphy may be useful in differentiating healthy eyes from those with normal-tension glaucoma (NTG), according to the authors of a recent study.
'Experienced' patients still have difficulty administering glaucoma dropsOctober 31st 2013
Even patients experienced with instilling topical glaucoma medications continue to have difficulties with eye drop administration, even those who do not self-report such difficulties, according to a recent study. Further, the risk of having difficulties with eye drop instillation is increased in patients who self-report difficulty and in those who have been previously observed to have difficulties.
SD-OCT measurements of RNFL thickness may help predict likelihood of glaucoma diagnosisOctober 21st 2013
Researchers have developed a methodology for calculating likelihood ratios for glaucoma diagnosis using continuous retinal nerve fiber layer (RNFL) thickness measurements taken with spectral-domain optical coherence tomography (SD-OCT), and found that average RNFL thickness values < 86 ?m were associated with negative likelihood ratios of such a diagnosis.
