Validating the Diagnostic Accuracy of Mediview 2.0 Software as an Image Analysis Tool of Meibomian...

Dry Eyes

Non-contact meibography is a useful tool in assessing the health of meibomian glands in patients. Instead of using normal light in contact meibography, non-contact meibography utilises infra-red (IR) light. IR light is shined on patients' inverted eyelids and a special camera then allows visualisation of the structure of the meibomian glands, including the ducts and acini. Currently, images taken via non-contact meibography are manually analysed by a skilled clinician. Knowledge of the health of meibomian glands is useful, especially in the diagnosis of Meibomian Gland Dysfunction (MGD). Studies have shown that MGD is one of the most common causes of evaporative dry eye. Mediview 2.0 is a software that has been programmed to semi-automatically classify meibograph images taken via non-contact meibography. This software is collaboration with Shanghai MediWorks Precision Instruments Co., Ltd. The algorithm used was developed by a collaboration between Agency for Science, Technology and Research (A*STAR) and Singapore Eye Research Institute (SERI). This current study aims to validate the diagnostic accuracy of Mediview 2.0 in assessing the health of meibomian glands of patients, against a trained clinician. We aim to recruit 100 participants for this study. Once this software is found to be valid, a trained technician could be taught how to capture the images and hence leaving the doctors with more time to focus on clinical assessment and treatment instead. Therefore, this study has the potential to increase efficiency in the clinics.

TearLab Refractive Surgery Dry Eye Study

Dry Eye Syndromes

The primary objective of this study is to determine how pre & post-operative tear osmolarity levels relate to rates of dry eye symptoms related to refractive surgery and if differences exist in patients who are pre-treated with ocular lubricants vs. those treated only post-operatively.

Corneal Tear Film Imaging of the Cornea Before and After Restasis Therapy

Dry Eye SyndromeTear Film Insufficiency

Dry Eye Syndrome (DES) is a disease affects the production and stability of the tear film, leading to vision disturbances and a major decrease in quality of life. The most recommended treatment for moderate-severe DES today which failed conservative therapy with lubricating eye drops is topical Cyclosporine 0.05% (Restasis®). The Tear Film Imager (TFI) is a novel imaging modality designed for visualization of the individual tear film layers up to a resolution of 0.1 micrometers, a property not enabled by any other imaging modality for this indication to date. In this study we wish to assess the effects of topical Cyclosporine 0.05% on the tear film using the TFI. In our previous study we found this modality yields high resolution images of the tear film, yielding significant differences between healthy and diseased (DES) eyes. We believe the TFI will improve quality of assessment and follow-up of DES patients, allowing more effective diagnosis and treatment of this disease in the future.

Evaluation of Dry Eye by Tear Film Imager in a Low Humidity Environmental Exposure Chamber (TFI-LH16)...

Dry Eye

The study consists of 3 study visits to the clinic over at least 9 days. Visit 1 - the medical screening visit: subjects will undergo informed consent and will be tested for signs and symptoms of Dry Eye Syndrome (DES) including measurements by the TFI. Upon conclusion of the screening for DES, the subjects will be divided to the different categories: NDE, LDDE and ADDE. For ADDE and LDDE subjects the eye fitting the worst DES inclusion criteria will be designated as the study eye. For the NDE subjects the best eye will be designated as the study eye. During Visit 2 and 3, the TFI measurement and other clinical study endpoint procedures will be only conducted on the study eye. The safety endpoint procedures will still be conducted on both eyes individually throughout the study. Subjects will be queried for adverse events (AEs) at all visits. Visit 2 - after two days washout period subject will return for the LH-EEC test. Signs and symptoms of dry eye will be recorded before entering the LH-EEC, during the 120 min stay in the LH-EEC and at the conclusion of the day. Visit 3 - after 7 days washout period subject will return for the last test. The third day procedure is identical to the second day, with the addition of: following LH-EEC exit, subjects will have a health check and study check out procedures conducted. Statistical Analysis: Data will be summarized with respect to baseline characteristics, efficacy variables and safety variables. Summary statistics will include the number of observations (N), mean, standard deviation (SD), median, minimum and maximum values for continuous variables and frequencies and percentages for categorical variables. Missing values will not be replaced or imputed, i.e., no interpolation or extrapolation will be applied to missing values. Safety data will be listed and summarized by group (NDE, ADDE, and LDDE).
