Abstract

AIM:To investigate the factors related to the decrease of corneal endothelial cell number after phacoemulsification in cataract patients. METHODS: We selected 98 patients(120 eyes)in Ophthalmic Center from July 2014 to July 2016 underwent phacoemulsification and they were retrospectively analyzed. According to the central corneal endothelial cell density before and 2mo after the operation, they were divided into serious loss group of 52 cases(67 eyes, density of central corneal endothelial cells loss rate no less than 12.3%), the general loss group of 46 cases(53 eyes, the density of central corneal endothelial cell loss rate RESULTS: Serious loss group and the general group on gender, rate with hypertension, rate with diabetes, rate with high blood lipids, with shallow anterior chamber, corneal diameter and suction time comparison, had no statistically significant differences(P>0.05). Nuclear hardness classification of Emery lens, ultrasonic power, ultrasonic emulsification time, age between groups were significantly different(PPCONCLUSION: The main factors that influence the decrease of corneal endothelial cell number after phacoemulsification are Emery lens, higher grade of nucleus of lens, increase of ultrasonic energy, longer time of phacoemulsification and increased age.

Abstract

AIM: To study a large glaucoma family by screening the disease-causing genes in order to understand the pathogenesis mechanism of glaucoma.METHODS: The diagnosis of glaucoma family was made by ophthalmological examination; peripheral blood was collected and the pedigree map was drawn. The genome DNA of the patients was extracted. The exons of MYOC, CYP1B1, OPTN, and WDR36 were amplified by PCR and sequenced. The data were analyzed by comparing the corresponding reference sequence in the database. Based on the target gene region capture technology, ophthalmic chip was used for further analysis. We were hoping to identify disease gene of the family or discover the new pathogenic site.RESULTS: Among all exons of MYOC, CYP1B1, OPTN, and WDR36, was no mutation gene identified as the disease causing gene, excluded most known candidate gene mutation of glaucoma and found 5 suspicious sites by the ophthalmic chip.CONCLUSION: Glaucoma is a polygenic disease, the known glaucoma-causing genes may not be involved the pathogenesis of the glaucoma in this family. Further studies are needed to identify the molecular basis of this family with glaucoma.

Abstract

AIM: To analyze the control effect of orthokeratology(OK)combined with atropine of low concentration on moderate to low myopia in adolescents.METHODS: Totally 76(152 eyes)adolescents with moderate to low myopia who were admitted to the department from January 2016 were enrolled. According to the voluntary principle, they were divided into orthokeratology group(OK group, n=36 cases, 72 eyes)and orthokeratology combined with atropine of low concentration group(combination group, n=40 cases, 80 eyes). The OK glasses were given for the two groups. The combination group was additionally given 0.1g/L atropine eye drops. All were followed up for 1a. The changes of uncorrected visual acuity, diopter, axial length, intraocular pressure, tear film function and corneal parameters were measured before and after wearing glasses. The incidence of complications was statistically analyzed.RESULTS: There were no significant differences in uncorrected visual acuity, diopter, axial length and intraocular pressure between the two groups before wearing glasses and at 1a of wearing glasses(P>0.05). The change of uncorrected visual acuity before wearing glasses and at 1a of wearing glasses of combination group was higher than that of OK group while the differences in diopter and axial length were lower than those of OK group(PP>0.05). At 1a of wearing glasses, LLT and BUT of combination group were higher than those of OK group while OSI was lower than that of OK group(PP>0.05). At 1a of wearing glasses, the changes of above indexes of combination group were lower than those of OK group(PP>0.05).CONCLUSION:OK glasses combined with atropine of low concentration can improve the uncorrected visual acuity of adolescents with moderate to low myopia, control the increase of diopter and axial length. And there is significant negative influence on corneal morphology and tear film function, and with high safety.

Abstract

AIM: To investigate camera-assisted measurement in evaluating the accuracy of Hirschberg Test in measuring squint angle of concomitant strabismus.METHODS:The clinical data of 105 patients with concomitant strabismus who were admitted to the hospital during the period from January 2016 to January 2018 were collected. After admission, they were given traditional Hirschberg Test and picture Hirschberg Test for squint angle examination.Taking the prism cover test as golden standard, the deviation values between squint angle measured by golden standard and those measured by the traditional Hirschberg Test and the picture Hirschberg Test were recorded.The influence of Kappa angle on the deviation value was analyzed.The application value of camera-assisted measurement in squint angle of concomitant strabismus was analyzed.RESULTS:There was a significant difference in the value of squint angle measured by traditional Hirschberg Test, picture Hirschberg Test and prism cover test test(PPPPPPPCONCLUSION: The deviation of camera-assisted measurement picture Hirschberg Test is lower than that of traditional Hirschberg Test for the measurement of squint angle of concomitant strabismus, and it is more suitable for young patients who cannot cooperate with.
