Neutrophil-to-lymphocyte ratio in ocular diseases: a systematic review

AIM: To summarize the results of studies investigating neutrophil-to-lymphocyte ratio(NLR) and to identify the role of NLR in ocular diseases. METHODS: With the aim of identifying the studies related to NLR, a search was conducted on http://www.ncbi.nlm.nih.gov/pubmed by utilizing the key words "neutrophil lymphocyte ratio, ocular diseases, and eye diseases" up to February 2018. All of the original articles were assessed according to date of publications, countries, clinics and topics. Studies about ocular inflammatory diseases were evaluated according to their qualifications, review methods and results. RESULTS: A total of 4473 publications, including original research articles and reviews were screened. The number of publications was shown a regular logarithmic increase over the years. The majority of studies were performed by clinics in Turkey and many of these publications were performed by oncology and cardiology clinics. A total of 75 publications were identified to be about ocular diseases. CONCLUSION: Elevated NLR as a cheap, reproducible, and readily available marker could be used as a diagnostic and/or prognostic marker in ocular diseases.

Clinical and impression cytology findings of amniotic membrane and oral mucosal membrane transplantation for the management of socket contracture

AIM:To investigate and compare the cytopathological and clinical effects of amniotic membrane transplantation(AMT)and oral mucosal membrane transplantation(OMMT)in socket contraction.METHODS:Twelve patients who could not be fitted with ocular prosthesis due to socket contracture were included in this study.Seven patients underwent AMT and 5 patients underwent OMMT.Thirteen patients who had healthy sockets were included as control group.Depth of inferior fornix,degree of inflammation,extent of the socket contracture and socket volume were measured in the preoperative period and at sixth and twelfth weeks postoperatively.Impression cytology of conjunctival fornices and tear transforming growth factor beta-1(TGFβ1)levels were determined.RESULTS:In the AMT group,socket volume and lower fornix depth values were significantly higher(P=0.030and P=0.004 respectively)and inflammation levels and impression cytology stages(P=0.037 and P=0.022respectively)were significantly lower in postoperative period compared to preoperative period.In the OMMT group,no statistical differences were found in terms of clinical parameters,inflammation levels and impression cytology stages of preoperative versus postoperative values.Preoperative tear TGFβ1 levels were higher in AMT and OMMT groups compared to the control group(25.5 ng/mL,26.3 ng/mL and 21.7 ng/mL respectively).Decreased tear TGFβ1 levels were observed in both the AMT and OMMT groups postoperatively(median decrease value=2.1 ng/mL and 2.7 ng/mL respectively).CONCLUSION:AMT is associated with postoperative improvement in inferior fornix depth,socket volume,inflammation and impression cytology levels and may bea more proper alternative method than OMMT in the management of socket contracture.
