New technique enables rapid eye pathogen detection

A new technique to detect eye pathogens has been developed by experts in Japan, which may lead to new diagnosis procedures and quicker ways of treating patients.

Dr Motoki Itahashi, and colleagues at Kinki University School of Medicine, Osaka-Sayama, Japan claim that a laboratory technique using real-time polymerase chain reaction (PCR) that copies DNA segments may allow clinicians to accurately identify pathogens infecting the cornea.

The authors wrote: "Although PCR has a high risk of false positivity, we actually treated the patients with positive PCR results only according to their real-time PCR results and the treatment outcomes were all satisfactory."

They added that, with real-time PCR, it may be possible to develop a diagnostic kit for pathogen-specific detection in ophthalmic clinical practice.

Meanwhile, a new development in a study carried out by Dr Ian McAllister, from Lions Eye Institute, Australia, shows that using lasers to create a bypass around the constricted retinal vein common in central retinal vein occlusion patients can restore near-normal blood flow to the retina.
