ABSTRACT

@#Impaired awareness of hypoglycaemia (IAH) is present in around 25-40% of individuals with type 1 diabetes mellitus (T1DM). Herein, we present a case of an adolescent with T1DM and IAH who had worse corneal nerve parameters compared to a T1DM adolescent without IAH. Small fibre abnormalities detected by corneal confocal microscopy in an objective easy-to-perform non-invasive test might be a surrogate indicator of underlying autonomic dysfunction in T1DM and IAH.

ABSTRACT

@#AIM: To investigate the clinical efficacy of anterior stromal puncture(ASP)for the corneal epithelial cells dysfunction(CED).<p>METHODS: Sixteen patients with CED underwent ASP in Wuhan Union Hospital from September 2015 to December 2015 were included. Uncorrected visual acuity, ocular surface disease index(OSDI), corneal fluorescence staining, corneal epithelial thickness, full corneal thickness, corneal subepithelial dendritic cell density, corneal endothelial cell density and corneal epithelial nerve density were observed and recorded at preoperative, 1mo and 3mo postoperatively, respectively.<p>RESULTS: Totally 16 patients compared with preoperatively, there was a significant increase in uncorrected visual acuity and corneal epithelial nerve density(<i>P</i><0.05)or a significant decrease in OSDI, corneal fluorescence staining, corneal epithelial thickness, full corneal thickness and corneal subepithelial dendritic cell density(<i>P</i><0.05)at 1mo postoperatively; while there was no significant difference in corneal endothelial cell density(<i>P</i>>0.05). And compared with 1mo postoperatively, there was a significant decrease in corneal subepithelial dendritic cell density(<i>P</i><0.05)and a significant increase in corneal epithelial nerve density(<i>P</i><0.05)at 3mo postoperatively, while there was no significant difference in uncorrected visual acuity, OSDI, corneal fluorescence staining, corneal epithelial thickness, full corneal thickness and corneal endothelial cell density(<i>P</i>>0.05).<p>CONCLUSION: ASP was effective for CED. Corneal confocal microscopy was essential for the evaluation of ASP efficacy, which can guide the clinical work better and establish the termination of intervention.

ABSTRACT

·Corneal confocal microscopy can be used in the real-time, noninvasive, high-resolution corneal structure at the cellular level, which has been widely used in corneal disease research. This review summarizes recent advances in corneal confocal microscopy in the study of infectious keratitis, dry eye, keratoconus, diabetic peripheral neuropathy, and clinical studies to guide corneal transplantation.

ABSTRACT

Objective To explore the diagnostic value of corneal confocal microscopy in the early small fibre neuropathy (SFN).Methods A total of 45 patients with small fibre neuropathy and 50 age-matched healthy subjects undertook a neurological evaluation,neurological deficits score (NDS),sural nerve conduction velocity,contact heat evoked potential (CHEP) and corneal confocal microscopy (CCM) to quantify small nerve fibre pathology.Four parameters including nerve fiber length (NFL),nerve branch density (NBD),nerve fiber density (NFD) and nerve fibre tortuosity (NFT) were calculated from the observation of corneal confocal microscopy.Results Compared with the control group,significantly decreased NFD and NBD were found in the SFN group [(42.00 ±25.26)/mm2 vs (72.38 ± 14.09) /mm2 ;(31.93 ± 13.21)/mm2 vs (46.24 ± 11.48)/mm2 ; with all P < 0.05],while NFT were significantly increased in the SFN group [(2.48 ±0.87) levels vs (0.88 ±0.56) levels,P <0.001].The neurological deficits score was correlated with NFT,NFD and NBD (r =0.782,-0.376,-0.504 ; with all P < 0.001).Conclusion CCM is a new and sensitive noninvasive clinical technique that may be used to detect early small fibre nerve damage in patients with SFN.
