Ocular examinations included visual acuity measurement, ocular motility evaluation, autorefraction under cycloplegia, and anterior segment, media, and fundus examination. Axial length (AL), anterior chamber depth (ACD), and corneal curvature radius were measured using partial coherence laser interferometry. A multivariate linear regression model was used for statistical analysis.Results: Twin children from Guangzhou city showed a decreased spherical equivalent with age, whereas both AL and ACD were increased and corneal curvature radius remained unchanged. When adjusted by age and gender, the data from 77% of twins presenting with spherical equivalent changes indicated that these were caused by predictable variables (R2 = 0.77, P < 0.001). Primary factors affecting children's refraction included axial length (β = -0.97,P < 0.001), ACD (β = 0.33, P < 0.001), and curvature radius (β = 2.10, P < 0.001). Girls had a higher tendency for myopic status than did boys (β = -0.26, P < 0.001). Age exerted no effect upon the changes in refraction (β = -0.01, P = 0.25).Conclusion: Refraction is correlated with ocular biometrics. Refractive status is largely determined by axial length as the major factor.","PeriodicalId":12096,"journal":{"name":"Eye science","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2014-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"33334832","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}

Three eyes had mild swelling of the optic disc and one eye had peripapillary scarring that corresponded to the permanent field defect. Two patients who underwent FFA had fluorescein leakage of blood vessels around the optic disc and ICGA highlighted diffuse, small hypofluorescent spots scattering throughout the posterior pole. OCT showed that the inner and outer segment (IS/OS) line were absent in five patients and the middle cone outer segment tip line was absent in the nasal macular area in one eye.Conclusion: AIBSES is a rare outer retinopathy. Visual field examination and OCT are the most important means of detection. ICGA and FAF can determine the range of lesions earlier, and the progress of the disease should be taken into account when making a diagnosis.","PeriodicalId":12096,"journal":{"name":"Eye science","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2014-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"33335280","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}

Patients underwent LASEK in one eye, and T-PRK in the other. The degree of pain was rated on a scale of 0-10 on postoperative days 1, 2 and 3. Uncorrected visual acuity (UCVA) and subepithelial corneal haze were assessed at postoperative 1 and 3 months.Results: The pain was relieved on the 4th postoperative day in all patients, healing of corneal epithelium was observed at 4-5 days after surgery and contact lenses were removed promptly. At postoperative 1 day, the mean subjective pain score in the LASEK group was 3.2 ± 1.88 and 4.43 ± 1.61 in T-PRK group (P = 0.008). No significant difference was found between two groups on postoperative 2 and 3 days. At postoperative 3 months, the percentage of UCVA ≥ 0.8 in the LASEK group was 100% and 96.7% in the T-PRK group (P = 0.24), 93.3% of patients in the LASEK with UCVA ≥ 1.0 and 90% in the T-PRK group (P = 0.64). In the LASEK group, the value of corneal haze was 0.26 ± 0.21 and 0.27 ± 0.25 in the T-PRK group (P = 0.877).Conclusion: Good visual acuity was obtained in both groups at postoperative 3 months. Compared with those in the T-PRK group, patients undergoing had less discomfort in the LASEK group, which may be associated with corneal epithelial activity. The changing curve of subjective pain in the T-PRK group was relatively flat and stable at postoperative 3 days.","PeriodicalId":12096,"journal":{"name":"Eye science","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2014-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"33335282","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 database with 367 subjects under 14 years of age (598, including second-round surgeries) was generated.Results: Of this cohort (n = 367; males: 232, 63.2%; females: 135, 36.8%), 200 patients (54.5%) had bilateral cataracts, and 258 (70.3%) were under 3 years of age. In all age groups and in all subtypes of pediatric cataract, males were most commonly affected. Congenital cataract was the most prevalent subtype, accounting for 296 patients (80.7%). Most congenital cataracts were associated with other ocular or systemic abnormalities; and in 48 patients (16.22%), they were hereditary. Traumatic cataract was the most common subtype (85.92%) of acquired cataract. The few instances of cataracts due to steroids (n = 3) or to metabolic disorders (n = 2) occurred in males and involved both eyes.Conclusion: The majority of pediatric cataracts in this patient population were congenital in nature. A significant lag in ophthalmologic evaluation of Chinese infants was evident and should be addressed by educating both children and parents on risk factors for cataract development. Regular assessments are especially important in children subjected to long-term systemic steroid treatments.","PeriodicalId":12096,"journal":{"name":"Eye science","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2014-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"33335279","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 mean value of each index of corneal curvature declined without statistical significance.Kmax value dereased from 60.91 to 59.91, and the astigmatism declined from 3.86 to 3.19.

Anterior segment and vitreous body examinations were unremarkable. Yellowish spots in the macular area were observed. Spectral domain optical coherence tomography (SD-OCT) imaging of the macula showed loss of the inner segment/outer segment (IS/OS) photoreceptor junction, with irregularity of the retinal pigment epithelium (RPE), and a V-shaped hernia of the retina into the choroid. The macular lesions emerged as mild window defects on fluorescein angiography and were visualized as hypofluorescent patches on all-phase indocyanine green angiography. At a one month follow-up, the best-corrected visual acuity improved to 20/20, which was followed by partial restoration of the IS/OS line, but a V-shaped hernia of the retina remained unchanged on SD-OCT.Conclusion: Ophthalmologists should be alert to the changes in OCT of the macula in patients after iridocyclitis and further research on the cause and possible predisposing factors for retinal herniation is warranted.","PeriodicalId":12096,"journal":{"name":"Eye science","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2014-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"33335286","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}
