Overnight orthokeratology lenses significantly increase ocular and corneal high-order aberrations (HOAs) and compromise contrast sensitivity function (CSF) to a degree correlated with myopic correction achieved. In Taiwan, OOK lenses are mainly used in children for myopia control. However, information regarding its effects in this population remains limited. This study discusses the change in HOAs and CSF after 28 nights of OOK lens use in children compared with that in adults.\u0000\u0000\u0000METHODS\u0000In total, 46 children (9-18 years) and 26 adults (>18 years) who visited Ophthalmology Department of Mackay Memorial Hospital from October to December 2013 were enrolled. Contrast sensitivity and ocular/corneal total high-order, coma, and spherical aberrations (SA) were tested before OOK treatment. After 28 days of overnight use, CSF and topography were reexamined, and data were collected and analyzed using t test and Pearson correlation coefficients.\u0000\u0000\u0000RESULTS\u0000In total, 23 eyes of 23 children and 14 eyes of 14 adults were evaluated. The treatment resulted in a significant increase in ocular total HOA, coma, and SA in both groups. However, CSF declined more in adults than children.\u0000\u0000\u0000CONCLUSION\u0000Our study revealed that OOK lenses decrease CSF to a greater extent in adults than that in children despite no significant differences in the change of ocular HOAs between both subject groups. We proposed children may have better neural adaptation to compensate for optical aberrations induced by OOK lens use.","PeriodicalId":12216,"journal":{"name":"Eye & Contact Lens: Science & Clinical Practice","volume":"52 11","pages":""},"PeriodicalIF":0.0,"publicationDate":"2020-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"91405180","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The aim of this study is to report on the repeatability and agreement between two different software programs that measure the contact angle with the captive bubble method in marketed CLs, which will help to translate this information into clinical practice.\u0000\u0000\u0000METHODS\u0000The contact angle of 23 different CLs was measured with the captive bubble method using 2 software programs: FTÅ200 and ImageJ. Three consecutive measurements were conducted for each CL. Reproducibility, repeatability, and agreement values were calculated according to the British Standards Institute and the International Organization for Standardization.\u0000\u0000\u0000RESULTS\u0000All methods showed good repeatability values in both CL materials (coefficient of variation <1.51%, Sw <2.26°, intraclass correlation coefficient >0.89, and the range of limits of agreement was between 7.22° and 7.57°). Higher concordance was achieved between the spherical and nonspherical options when using FTÅ200 software than when using ImageJ software. Statistically significant differences (P<0.05) between the 2 software programs were found, and they ranged between 5° and 10°.\u0000\u0000\u0000CONCLUSIONS\u0000The captive bubble method showed great repeatability in measuring the contact angle in marketed CLs with both software programs (FTÅ200 and ImageJ) assessed in this study. However, differences in the measured contact angles suggest that these techniques are not interchangeable. Therefore, standardization is recommended for contact angle measurement in hydrogel CL materials to facilitate comparisons, to improve clinical use of this information, and to analyze their impact in CL user comfort.","PeriodicalId":12216,"journal":{"name":"Eye & Contact Lens: Science & Clinical Practice","volume":"19 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2020-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"84528670","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

We calculated sensitivity, specificity, false-positive rate, false-negative rate, and positive and negative predictive values of biomicroscopic examination compared with those of positive light microscopy.\u0000\u0000\u0000RESULTS\u0000Of the 255 subjects included in the study, 134 (52.5%) were men and 121 (47.5%) were women. The mean age was 43.9±11.9 years. Of the 255 chronic blepharitis cases, 130 (51%) presented Demodex infestation on light microscopy. We calculated the sensitivity, specificity, false-positive rate, false-negative rate, positive predictive value, and negative predictive value and were found to be 83.07%, 90.4%, 9.6%, 16.9%, 90%, and 83.7%, respectively, for the biomicroscopic examination.\u0000\u0000\u0000CONCLUSIONS\u0000Careful biomicroscopic examination can be time-efficient and cost-effective, and the need for more advanced and invasive procedures for the identification of Demodex in patients with chronic blepharitis can be reduced.","PeriodicalId":12216,"journal":{"name":"Eye & Contact Lens: Science & Clinical Practice","volume":"16 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2020-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"85417670","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

A 15-item questionnaire regarding MGD-related ocular symptoms was administered to all patients. Both prosthetic eyes and paired normal eyes were evaluated with slit-lamp, noncontact meibography and spectral optical coherence tomography. A multiple linear regression model was applied to evaluate factors on ocular symptom scores.\u0000\u0000\u0000RESULTS\u0000The ocular symptom scores, meibography scores, meibomian gland loss, and lid margin abnormality scores of prosthetic eyes were significantly higher than those of normal eyes (P<0.05). Tear meniscus measurements of eyes with prosthesis were significantly lower from those of normal eyes (P<0.05). The ocular symptom scores were significantly positively correlated with meibography scores, meibomin gland loss, and lid margin abnormality scores and negatively correlated with tear meniscus measurements (P<0.05). There was a significant negative correlation between total meibography scores and all tear meniscus parameters (P<0.05). The patients who had used ocular prosthesis for longer durations had a significantly greater meibography scores, meibomin gland loss, lid margin abnormality scores, and ocular symptom scores but lesser tear meniscus parameters (P<0.05).\u0000\u0000\u0000CONCLUSION\u0000Use of ocular prosthesis is significantly associated with MGD, which is proportional to the duration of prosthesis wear. Furthermore, ocular discomfort symptoms of prosthetic eye wearers significantly correlated with MGD-related dry eye.","PeriodicalId":12216,"journal":{"name":"Eye & Contact Lens: Science & Clinical Practice","volume":"1 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2020-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"72800626","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
