DRy Eye Outcome and Prescription Study
Dry EyeDry Eye Syndrome8 moreThe DRy eye Outcome and Prescription Study (DROPS) is a large observational multicentre study exploring the 'real world' effectiveness of artificial tears in dry eye disease and determinants of efficacy. The aim is to include at least 635 symptomatic dry eye patients who are prescribed artificial tears. All trainees and fellows in London are invited to become collaborators: collaborators are asked to consent patients, assess signs at baseline, and give patients questionnaires at baseline and 4 weeks (for home completion). In tandem, we are conducting a qualitative review of ophthalmologists' prescribing behaviours for dry eye disease.
Application of Real-time PCR Platform for Detection of Vittaforma Corneae Among Patients With Microsporidia...
Microsporidia KeratitisMicrosporidial KeratoconjunctivitisDiagnosis of patients with microsporiosis relies on pathological findings as well as laboratory detection of the causative organism. The conventional laboratory diagnosis of microsporiosis relies on microscopic visualization of the characteristic V. Corneae organisms. We develop a fully automated molecular platform for detection of Vittaforma corneae among patients with microsporidia keratitis.
Reliability of Pachymetry Measurement With FD-oCT, ORA, Confoscan 4 and Ultrasound
KeratitisThe purpose of this study is to assess the repeatability, reproducibility, and agreement of central corneal thickness measured by Fourier Domain Optical Coherence tomography (FD-OCT, OptoVue, USA) with anterior corneal module, 20MHz ultrasound pachymetry equipped with Ocular response analyzer (ORA, Reichert Ophthalmic Instruments, USA) and 10MHz Ultrasound Pachymetry (USP).

EndophthalmitisKeratitis2 moreThe aim of this study is to see if multiplex strip PCR will detect the pathogen that causing eye infection from the corneal scraping samples with higher sensitivity and specificity than the current gold standard.
The Asia Cornea Society Infectious Keratitis Study
Corneal UlcerCorneal diseases are a major cause of blindness worldwide, and corneal infections are a substantial cause of blindness in Asia. The aim of the Asia Cornea Society Infectious Keratitis Study (ACSIKS) is to study infectious keratitis (corneal infections) in Asian countries, so as to improve strategies for prevention and treatment, and to reduce the burden of blindness in Asia. The first phase of ACSIKS is an 18-month observational study involving 11 eye hospitals in 8 Asian countries; these hospitals manage more than 6700 cases of corneal infections every year. From the first quarter of 2012, all patients with a corneal infection will be recruited and a standard ACSIKS protocol will be applied; this protocol includes the use of a common set of study forms and a suggested panel of microbiological examinations. However, each centre will be continue to treat their patients with the anti-infective therapy standard for their centre. Data will be recorded for each patient for a period of six months, including their medical and surgical management, the final clinical outcome and vision. Bacterial and fungal growths from patients will also be stored for further research during a second phase of ACSIKS. These studies will focus on evaluating the resistance of the most common bacterial infections to the current available antibiotics, performing DNA testing to compare our strains with bacterial infections in the West, and to developing new diagnostic tests and anti-infective therapies tailored to corneal infections in Asia.
