ABSTRACT
@#AIM: To investigate the vision-related quality of life after corneal refraction surgery of the new recruits in a navy unit. <p>METHODS:New recruits in a navy unit during 2014-2016 were interviewed druing recheck ophthalmic examination through a questionnaire, including basic data and the Visual Function Questionnaire-25(VFQ), and also checking the visual acuity, contrast sensitivity(CS), optometry.<p>RESULTS: Among 2 760 new recruits, 340 persons(12.32%)had undergone corneal refractive surgeries, which included corneal stroma surgery(89.71%)and corneal surface surgery(10.29%). According to the preoperative myopia spherical equivalent, the subjects were divided into three groups: mild myopia group(≤-3.00D, 134 cases), moderate myopia group(>-3.00 D to < -6.00D, 159 cases), and high myopia group(≥-6.00D, 47 cases). The postoperation spherical equivalent range ±1.0D is 128 cases(95.52%), 153 cases(96.23%), 38 cases(80.85%)in mild myopia group, moderate myopia group and high myopia group respectively. The contrast sensitivity(CS)were statistically significant among three different diopter groups under natural light and glare conditions(<i>P</i><0.05), the CS of the low myopia group and moderate myopia group were higher than in high myopia group(<i>P</i><0.05). The visual-related quality of life scores were statistically significant among three group(<i>P</i><0.05). The scores of low(6.25±8.61)points and moderate myopia groups(6.87±8.51)points were significantly better than that of high myopia group(9.84±9.76)points(<i>P</i><0.05).<p>CONCLUSION:The vision-related quality of life in new recruits after corneal refractive surgery in the unit is related with preoperative diopter of refractive error. The vision-related quality of life in recruit with lower diopter are better than in recruit with higher dioper.
ABSTRACT
@#AIM: To study the characteristics and related influencing factors of subfoveal choroidal thickness(SFCT)changing with time in children with myopia. <p>METHODS: Totally 60 eyes of 60 children with myopia aged 6-15 years old who were admitted to the Eye Hospital of Nanchang University from July 2018 to September 2018 were included. IOP, axial length, equivalent spherical degree and SFCT were measured at baseline and 6mo of follow-up, respectively. Analyze the changes of the above-mentioned eye parameters and related influencing factors of SFCT. <p>RESULTS: Compared with baseline, follow-up for 6mo, myopic children's SFCT decreased by 8±14μm(<i>P</i><0.001), the axial length increased by 0.15±0.16mm(<i>P</i><0.001), and the equivalent spherical degree increased by -0.34±0.33D(<i>P</i><0.001), and there is a significant correlation between the SFCT change value and the axial length and equivalent spherical power change value(<i>r</i>s=-0.701, 0.633, both <i>P</i><0.001), indicating faster axial growth and myopia increasing is related to more thinning of the membrane thickness. Multiple linear regression analysis shows that SFCT is significantly correlated with axial length(<i>P</i>=0.001).<p>CONCLUSION: The SFCT of myopic children becomes thinner over time, and the axial length is negatively correlated with SFCT, and children with faster axial growing and greater myopia increasing are usually accompanied by more SFCT thinning.

ABSTRACT
@#AIM: To investigate the effect of blocking short wave visible light(400-500nm)on tear film stability in healthy people. <p>METHODS: In this prospective intervention experiment, 26 college students were selected, including 12 males and 14 females, aged 22.1±1.4 years, from February to March 2020. At the same time of two adjacent days, the subjects watched the video for 1h under the same environmental conditions. For the first time, there was no short wave visible light blocking, and for the second time, they wore short wave visible light blocking myopia or flat glasses. The subjects were examined the radius of curvature of lacrimal River curved surface, tear osmolality, tear film rupture time, corneal fluorescein sodium staining score, the basic state before watching the video and after watching the video respectively. And the questionnaire of visual perception was completed at the end of the experiment. <p>RESULTS: There were significant differences in the radius of curvature of lacrimal River curved surface, tear osmolality, tear film rupture time, corneal fluorescein sodium staining score between the basic state and the short wave visible unstopped state(<i>t</i>=4.50, 5.72, 4.437, 3.245, <i>P</i><0.05). There was no significant difference between the short wave visible light blocking and the basic state(<i>t</i>=1.972, 1.993, 1.921, 1.641, <i>P</i>>0.05). There was also significant difference between the short wave visible light blocking and the short wave visible light unblocking(<i>t</i>=2.825, 3.771, 2.610, 3.028, <i>P</i>< 0.05). The results of the questionnaire showed that: eighteen subjects(69%)said that wearing the short wave visible light blocking glasses or without wearing short wave visible light blocking glasses had slight eye dryness, pain, foreign body sensation, visual fatigue and other discomfort after watching the video. Sixteen subjects(62%)said that they were more comfortable after blocking the short wave visible light. Twenty-four subjects(92%)said that they were willing to block the short wave visible light. <p>CONCLUSION: The stability of tear film could be reduced by watching the display screen for a short time. Blocking the short wave visible light could protect the stability of tear film of the ocular surface.
