Retinitis pigmentosa (RP) is a hereditary disease characterized by the progressive loss of photoreceptor cells. Disease pathology primarily affects rod photoreceptor cells first but light-insensitive cone photoreceptor bodies can survivor longer. Delivered by adeno-associated viral vector or lentiviral vector, expression of microbial-type rhodopsin, channelrhodopsin-2 or archaebacterial halorhodopsin in the survived retinal cells can substitute for the native phototransduction cascade in mouse models of retinitis pigmentosa. It can also restore light sensitivity and activate all retinal cone pathways and drive sophisticated retinal circuit functions. Thus, expression of channelrhodopsins or halorhodopsin might be a potential strategy for the restoration vision of patients with RP.

Background The ocular nerve of trigeminus is the sensation and nutrition nerve of cornea.Whether trigeminal neuralgia affect the function of ocular surface and the morphology of corneal nerve plexus or not is below understanding.Confocal microscope is a non-invasive method for in vivo corneal examination.Objective This study was to analyze the ocular surface findings and observe the morphology and density of corneal nerve under the confocal microscopy in patients with trigeminal neuralgia.Methods Thirty-three eyes of 33 patients with trigeminal neuralgia were collected from the Department of Pain Management in Henan Provincial People's Hospital.The corneal perceptual sensitivity was examined using corneal aesthesiometer,and the function of lacrimal secretion (Schiemer Ⅰtest),tear break-up time (BUT) were performed to evaluate the influence of trigeminal neuralgia on ocular surface.The change of corneal nerve was observed under the confocal microscopy.The fellow eyes served as controls.The informed consent was obtained from the subjects before any examination.Results The fiber length of corneal perceptual sensitivity was (54.348±6.793)mm and (55.217±6.480)mm in trigeminal neuralgia group and control group without a significant difference between them (t=0.641,P=0.528).No significant differences were found in the mean value of Schiemer Ⅰtest (9.390±6.583mm vs 9.300±5.295mm) and BUT result (6.09±4.177s vs 6.13±4.799s) between trigeminal neuralgia and control group(t=0.070,P=0.945;t=-0.085,P=0.933).The densities value of corneal subepithelial nerve plexus at the nasal,temporal,superior,inferior and central area was insignificantly changed between trigeminal neuralgia group and control group(P=0.840,0.459,0.268,0.120,0.607).Tenuous,bending and circling nerve fibers were seen in corneal stroma under the confocal microscope,while the nerve fibers were strict in controls.Conclusion Trigeminal neuralgia does not dramatically affect eye surface function and corneal subbasal nerve plexus density,but corneal nerve fibers with trigeminal neuralgia are more bending than normal people.

Background Noninvasive methods such as in vivo confocal microscopy and Orbscan Ⅱ corneal topography have been used to examine ocular surface structure at the cellular level.However,very few domestic reports about the corneal structures of experimental animals investigated by confocal microscopy are available.Objective This study was to compare the anatomical differences of the corneal structures of three frequently used experimental animals presented by in vivo confocal microscopy,and to offer a database on the information provided by the in vivo study of the corneal structures of these animals.Methods Bilateral corneas of 3 clean adult male New Zealand rabbits,3 clean adult male Lewis rats and 3 clean adult male Swiss mice were examined by in vivo confocal microscopy.The morphological characteristics of every layer of the corneas and the endothelial cell densities were analyzed and compared.Results Superficial epithelium cells of the three animal models were characterized as polygon cells with high or low reflective border.The arrangement of the basal epithelial cells was regular with tight contacts but these cells lacked visible nuclei.The Bowman' s layer of cornea presented as an amorphous sheet containing abundant subepithelial plexus.In the rabbits,a highly reflective structure in the corneal stroma wasconfirmed as the nucleus,and the cell density of the posterior stroma was significantly lower than that of anterior stroma(387.5 cells/mm2 versus 223.5 cells/mm2)(U =0.000,P =0.000).Massive light-reflecting astreoids were displayed in the stroma of the rats and the mice.Corneal endothelial cells(CECs)of the three animal models had similar shapes and arrangements,presenting with high refractive cell bodies with dark borders and honeycomb-like arrangements.The CECs densities were 2192.5,1936.0,1565.0 cells/mm2 in the New Zealand rabbits,Lewis rats and Swiss mice,respectively,showing a statistically significant difference among them(H =49.940,P =0.000),and that of the rabbits was significantly higher than that in the rats and mice(x2 =0.000,P =0.000;x2 =0.000,P=0.000).Significant difference was also seen between the rats and the mice in the CECs densities(x2=0.000,P=0.000).Conclusions The CECs of the three animal modes are similar in morphology.But the structures of their stromal cells and endothelial cell densities are different.The combination of in vivo confocal microscopy and Orbscan Ⅱ corneal topography offers high-resolution imaging for each layer of the cornea.
