ABSTRACT

Background Excimer laser corneal refractive surgery is widely used because it reduces the dependency of refractive error eye to glasses.However,the adverse effects of anti-inflammatory drugs is a problem after operation.Lotemax eyedrops is a kind of steroidal anti-inflammatory drug,with a good effect on the operative eye.But its influence on intraocular pressure(IOP) after long-term topical administration is less studied.Objective This study was to investigate the influence of lotemax eyedrops on IOP after long-term topical administration in myopic eyes received excimer laser corneal refractive surgery.Methods An one-month retrospective case serial study was adopted.The case history data of 1552 eyes from 1552 Patients who received excimer laser corneal refractive surgery were collected in Tangshan Eye Hospital from 2011 January to 2012 January,including 321 eyes with laser in situ keratomileusis(LASIK),608 eyes with sub-Bowman keratomileusis (SBK) and 623 eyes with femtosecond laser for flap excimer laser in situ keratomileusis(FS-LASIK).Lotemax eyedrops was topically administered after operation 4 times per day initial and then decreased 1 time weekly for 1 month.IOP was measured in before,1 week,2 weeks,3 weeks,4 weeks after operation with non-contact tonometer.The increasing range of IOP was divided into <5 mmHg,5-15 mmHg and > 15 mmHg after operation.Optical head parameters were measured by Heidelberg retina tomography when IOP increasing after operation.Results Within 1 month,elevated IOP was found in 47 of 1552 eyes after administration of lotemax eyedrops,including 3.12% (10/321) in the LASIK group,3.29% (20/608) in the SBK group and 2.73% (17/623) in the FS-LASIK group,without significant difference among them(x2 =1.95,P>0.05).The IOP elevated 1 week after operation and remained normal after that till drug withdrawal in all eyes.There were no significant differences in the disk area (1.65 ±0.44) mm2 vs.(1.66 ±0.44) mm2,disk volume (0.40 ±0.09)mm3 vs.(0.39±0.08) mm3 and mean nerve fiber layer thickness (0.28 ± 0.08) mm vs.(0.29 ± 0.07) mm in IOP elevation duration compared with 1 month after IOP recovery(t =0.34,0.81,0.48,P>0.05).Conclusions Topical administration of 0.5% lotemax eyedrops after excimer laser corneal refractive surgery leads to reversible high IOP.It is very important to monitor the IOP during use of the drug.

ABSTRACT

Background Pathologic myopia is one of the common blinding eye diseases.Recent research suggests that immune response participates in the pathogenesis of pathologic myopia,and inflammation is an important factor that influent immune status.Objective Present study was to observe the change of high sensitive C-reactive protein(hs-CRP) in serum in the patients with pathologic myopia and explore the role of inflammation in the development of pathologic myopia. Methods Serum hs-CRP was measured from 30 patients with pathologic myopia,30 patients with simple myopia and 30 normal controls with Nephelometric Turbidity in the OLYMPUS AU5400 automatic biochemical analyzer.Written informed consent was obmined from each subject before medical examination.Results The mean age was(30+10) years in pathologic myopia group,and(32+8)years in simple myopia group and(32+9)years in normal control group.The range of preoperative spherical equivalent refraction was (-6.00--22.00) D in pathologic myopia group,(-1.00--6.00) D in simple myopia group and(-1.00-+1.00) D in normal control group.The level of hs-CRP in serum was(3.68±1.15)mmol/L in the patients with pathologic myopia and was significantly higher than that of simple myopia group(1.99±0.68 mmol/L)and normal controls (2.11±O.66 mmol/L)(q=10.69,P<0.01;q=9.91,P<0.01),respectively.No significant correlation was found between hs-CRP level and myopic degrees in pathologic myopia group(R2=0.037,P>0.05). Conclusion Hs-CRP may play rule in the inflammatory reaction during the pathogenesis of pathologic myopia.

ABSTRACT

Objective To investigate the prevalence, common clinical symptoms and complications, transmission routes and media of brucellosis among human in the city of Songyuan in Jilin province, and to provide practical basis for brucellosis intervention and related control measures. Methods Use self-designed questionnaire to collect information from outpatients in brucellosis clinic in Songyuan Center for Disease Control and Prevention from January to June 2009, and to analyze the related data from the survey: prevalence, time and geographical distribution, clinical symptom, transmission route and media. Results Of the total 620 cases investigated, there were 284 patients accounting for 45.8% (284/620), 75 suspected patients accounting for 12.1% (75/620), 13stealth patients accounting for 2.1% (13/620) and 248 negative people accounting for 40.0% (248/640). Main common symptoms of the patients were fever[66.5%( 189/284)], muscle and joint pain[38.7%( 110/284)],fatigue[27.5%(78/284)], hyperhidrosis[25.0%(71/284)]and low back pain[17.3%(49/284)]. The patients group had a significantly higher prevalence of mucocutaneous infection, contacting infected animal abortion flow,fur, soil, faeces and dust than the uninfected group(χ2 value were 27.12, 22.75, 8.90, 6.65, 6.39, 6.39, all P< 0.01 or < 0.05). Conclusions The positive rate of brucellosis in the brucellosis clinic of Songyuan city is high,and patients have typical symptoms. We should take comprehensive control measures to protect the high-risk group and reduce the local infectivety.

ABSTRACT

<p><b>OBJECTIVE</b>To investigate the incidence of myopic retinopathy and its risk factors.</p><p><b>METHODS</b>The fundus of 1449 patients (2879 eyes) with myopia were retrospectively examined. The clinical relationship between myopic retinopathy and diopter, age, and sex was analyzed.</p><p><b>RESULTS</b>Myopic retinopathy was detected in 413 eyes (14.35%). Posterior pole retinal lesions were detected in 22 eyes (0.76%). Peripheral retinal lesions were found in 396 eyes (13.75%). According to their diopters, the myopic patients were divided into four groups: low, medium, high and super high myopia The incidence of peripheral retinal lesions was 4.18%, 8.72%, 19.18%, and 37.44% in these four groups, which significantly different (chi2 = 178.594, P<0.001). By age these patients were divided into three groups: I group, age <25; II group, age 25-34; III group, age >34. The incidences of peripheral retinal lesions in these three groups were 8.11%, 15.34%, and 24.59%, which were significantly different (chi2 = 76.090, P<0.001). The incidence of retinal lesion in male and female was 9.32% and 16.07%, respectively, which was significantly different (chi2 = 24.886, P<0.001). Posteriorpole retinal lesions were only detected in the highly or super highly myopic patients, all of them were more than 25 years. The incidence of posteriorpole retinal lesions in the highly and super highly myopia group was 0.86% and 6.67% respectively, which was significantly different (chi2 = 31.898, P<0.001). The incidence of posteriorpole retinal lesions in group II and group III was 0.55% and 3.55% respectively, which was significantly different (chi2 = 22.523, P<0.001).</p><p><b>CONCLUSIONS</b>The prevalence of retinal lesions in myopic patients is higher than that of emmetropia. The incidence of peripheral retinal lesions increases in patients with deeper diopters. Posterior pole retinal lesions usually occur in the myopic patients whose age are more than 25 years and diopter more than - 6.00 D. Careful examination of fundus is essential for early detection and timely treatment.</p>

ABSTRACT

<p><b>OBJECTIVE</b>To evaluate the effectiveness of laser in situ keratomileusis (LASIK) for myopia after 2 year follow-up.</p><p><b>METHODS</b>LASIK surgery was performed for 95 eyes (49 cases) with refractive dioptres (from -1.00 to -16.50 D), and then followed up for more than 2 years. The preoperative spherical equivalent was -1.00(-)-16.50 (-6.73 +/- 2.02) D. Patients were divided into two groups including group I with mild to moderate myopia (< or = -6.00 D) and Group II with severe myopia (more than -6.00 D).</p><p><b>RESULTS</b>In group I, uncorrected visual acuity more than and equivalent to 1.0 was in 40 eyes (93.02%), more than and equivalent to 0.8 in 43 eyes (100%). In group II, uncorrected visual acuity larger than and same as 1.0 was in 37 eyes (71.15%), larger than and same as 0.8 in 45 eyes (86.54%), larger than and same as 0.5 in 50 eyes (96.15%), and less than 0.5 in 2 eyes (3.85%). The mean spherical equivalent changed from (-4.14 +/- 0.86) D to (-0.04 +/- 0.14) D in group I and from (-9.00 +/- 1.64) D to (-0.08 +/- 0.20) D in group II. Significant difference was seen in these two groups (P < 0.001). The keratometric powers (K) were reduced from (44.31 +/- 0.78) to (40.11 +/- 1.23) and from (45.46 +/- 1.00) to (38.01 +/- 1.73) respectively, which showed significant difference (P < 0.001).</p><p><b>CONCLUSION</b>The effectiveness of LASIK for mild to moderate myopia or severe myopia is promising and safe.</p>

ABSTRACT

<p><b>OBJECTIVE</b>To evaluate the static and dynamic contrast sensitivity changes in myopic patients before and after laser in situ keratomileusis (LASIK).</p><p><b>METHODS</b>Seventy-three eyes in 37 patients with myopia (with or without astigmatism) who received LASIK were tested for static and dynamic contrast sensitivities using the METRO VISION MON ELEC I system at 0.7, 1.4, 2.7, 5.5, 11, and 22 cpd and cps prior to LASIK, and at one-, three-, and six-month intervals after LASIK.</p><p><b>RESULTS</b>All eyes gained naked visual acuity of more than 0.5 after LASIK. The contrast sensitivity was depressed at all frequencies 1 month after LASIK, as compared to one week prior to LASIK. The depression at 2.7, 5.5, 11 (P < 0.01) and 22 cpd (P < 0.05) was statistically significant for static contrast sensitivity, and also at 5.5 (P < 0.01) and 11 cps (P < 0.05) for dynamic contrast sensitivity. Myopic eyes between 6.25 D and 14.0 D, and astigmatic eyes 2 DC and more, suffered more static and dynamic contrast sensitivity depression than the myopic eyes between 1.25 D and 6.00 D and astigmatic eyes less than 2 DC. Contrast sensitivities were improved and exceeded preoperative levels 3 months after LASIK, and improved even more 6 months after LASIK. All sequences were statistically significant for static contrast sensitivity (P < 0.01), while only 2.7, 5.5, and 11 cps were statistically significant for dynamic contrast sensitivity (P < 0.01). The astigmatic eyes 2 DC and more showed less improvement, even below the preoperative level at 1.4 cps of dynamic contrast sensitivity.</p><p><b>CONCLUSIONS</b>While temporary depression of contrast sensitivity for myopic eyes after LASIK was seen, contrast sensitivity soon returned to exceed preoperative levels at 3 months after LASIK, while improving even more 6 months after LASIK.</p>
