Chinese Journal of Experimental Ophthalmology 2011;29(4):363-366
Background The early diagnosis and treatment is vital for the age-related macular degeneration (AMD).Previous examining methods were fundus fluorescein angiography(FFA)and optical coherence tomography (OCT).However,a new diagnostic technique,fundus autofluorescence(FAF),is applying in ophthalmology.objective This study was to observe the FAF characteristics of atrophic AMD. Methods Thirty-nine eyes of 28 patients with atrophic AMD were diagnosed and collected in our hospital and classified based on the criteria of Chen Song.FAF was performed by a confocal scanning laser ophthalmoscope(Heidelberg Retina Angiograph 2,HRA2).Characteristics of FAF images were compared with FFA images or color fundus photographs.Written informed consent was obtained from each patient prior to the examination. Results Areas with abnormal increased or decreased FAF signals were consisted or unconsisted with funduscopically visible alterations.Seven manifestations of FAF were found in the eyes with preatrophic stage of atrophic AMD,including slight change,focal increase pattern,patchy pattern,linear pattern,lacelike pattern,reticular pattern,and speckled pattern.In atrophic stage of atrophic AMD,geographic atrophy showed a well-defined hypoautofluorescence area;while non-geographic atrophy showed a ill-defined hypoautofluorescence area.There were three abnormal FAF patterns(focal,band and diffuse)in the junctional zone of geographic atrophy and diffuse pattern in the junctional zone of non-geographic atrophy. Conclusion FAF imaging is helpful for the diagnosis of atrophic AMD as a new non-invasive technique.

Cas9 is a RNA-guided double stranded DNA nuclease that participates in the CRISPR/Cas9 system. Wide-type Cas9 directly silences the expression of target gene by gene splicing. The engineered dCas9 protein with the mutation at D10A and H840A lacks the Cas9' s endonuclease function but keeps its DNA binding activity. dCas9 can activate special genes by fusing with transcription activator. Meanwhile,it can inhibit the gene transcription by directly binding to the target gene and stop gene transcrip?tion. Combination of light sensitive structures and CRISPR can produce light-inducible CRISPR/Cas9 system for control of gene expres?sion. This system is able to activate or inhibit gene expression via the use of controlling blue light(470 nm). In this review,we mainly discuss the development of the light inducible CRISPR/Cas9 system as well as its application in the control of gene expression.
