Adaptive Optics ScanningLaser Ophthalmoscope Safety and Efficacy Clinical Trial

Adaptive Optics ScanningLaser Ophthalmoscope Safety and Efficacy Clinical Trial

This prospective, multicenter, single-group, target-value clinical trial was designed to evaluate the efficacy and safety of an Adaptive Optics ScanningLaser Ophthalmoscope(AOSLO) for ophthalmic examination.

objective: This study aims to collect AOSLO retinal images from human population to assess the imaging quality and quantitative measurement consistency of AOSLO devices manufactured by Robotrak and also monitor any possible side effects.

study population: randomly invited 194 volunteers who meets inclusion criteria

design: the study is an observational protocol that participants will be imaged with Robotrak AOSLO systems to get cellular level images of photoreceptors and blood vessels in foveal area. Automatics analysis of cell/blood vessel morphology parameters will be calculated for consistency evaluation. In general, participants will undergo a complete ophthalmic examination including assessments of visual acuity, intraocular pressure, slit lamp examination, ocular biometry, OCT, fundus imaging, multi-focal ERG and OCT scan to assess potential side effects of AOSLO imaging.

outcome measures: the primary efficacy outcome measure of this study are multi expert grading of the image quality collected.

the secondary efficacy outcome measure are quantitative assessment of the morphological parameters generated from the captured images and device operator ratings.

the safety measures are side effect signs from ophthalmic examinations before&after AOSLO imaging

4. Aphthalmic or intraocular lens eyes
5. Those who have received photodynamic therapy within 48 hours;
6. Individuals with a history of photosensitivity or taking medication that may cause photosensitive side effects 7）Those who have obvious skin lesions on the lower jaw or forehead and are unable to contact the lower jaw or forehead support

8) Individuals with epidemic keratoconjunctivitis or in the active phase of other infectious diseases 9) Those whose refractive medium is turbid and unable to obtain satisfactory images; 10) Poor fixation or inability to cooperate with the examination due to other reasons; 11) Pregnant or lactating women;
