Researchers have postulated that the transient vascular alterations during each migraine attack lead to ischemic damage in the eye which can be measured via optical coherence tomography. Methods: We recruited 29 volunteers: 13 migraineurs (mean age 28 ± 8.8 years;12 female and 1 male) and 16 age-matched controls (mean age 26.6 ± 6.9;9 female and 7 male). All individuals underwent a detailed ophthalmic examination by a qualified optometrist and a Migraine Disability Assessment. The investigators were blind to the migraine diagnosis. Retinal Nerve Fiber Layer (RNFL) thickness, Retinal Thickness (RT), Ganglion Cell Complex (GCL), ranging from the inner-limiting membrane to the inner plexiform layer, and Choroidal Thickness (CT) were measured using the 3D OCT-1Maestro, Topcon, a Spectral Domain OCT (SD-OCT) device. Results: In the migraine population average RNFL was lower for several parameters. However, results did not reach statistical significance. A significant decrease in the right eye inferior parafoveal ganglion cell layer in the migraine group of patients (mean = 25.15, SD = 4.08) compared to normal healthy controls (mean = 28.81, SD = 4.85;t = (27) = 2.17, p = 0.039) was documented. No other ganglion cell layer or choroidal thickness reached significance. No significant relationship between ocular thickness parameters and MIDAS score, parameters and either MIDAS score or frequency of headaches was found. Conclusion: A significant decrease in the right inferior parafoveal ganglion cell layer for migraine patients was reported. All other parameters did not reach significance. .展开更多

The aim of the study was to identify the demographic and clinical features of infectious endophthahnitis in Western China for better prophylaxis and treatment of this disease. Methods： A retrospective, cross-sectional study was conducted based on the medical records of inpatients having infectious endophthahnitis in a tertiary referral center in Western China between 2005 and 2016. Results： The common cause of infectious endophthahnitis was trauma （82.6%）, endogenous （7.8%）, ophthalmic surgery （6.9%）, and corneal ulcer with perforation （2.7%）. These four etiological groups differed in age, gender, enucleation rate, visual outcome, etc. The number of cases in the first 6 years accounted for 38.7% of the total collection, which in the second 6 years accounted for 61.3%. The etiology patterns were different between these two periods. Altogether 51.3% of patients received pars plana vitrectomy, 13.9% of patients underwent evisceration, and the remaining 34.8% received other treatments. Of the 670 cases that had culture results, 266 （39.7%） were culture positive and 177 （66.5%） were Gram-positive organisms, 64 （24.1%） were Gram-negative organisms, 11 （4.1%） had fungal infection, and 14 （5.3%） were infected by multiple pathogens. Conclusions： There was an upward trend of the occurrence of infectious endophthalmitis in Western China for the past decade. The demographic and clinical characteristics of infectious endophthahnitis in Western China had its own characteristics and differed from those of developed cotintries. Here, open globe trauma was the most common cause ofendophthalmitis, most traumatic endophthalmitis patients were male, and most of the injuries were work related, implicate that we should strengthen the education and application of ocular safety regulation specifically targeting the workplace.展开更多
