OBJECTIVEA systematic review of literature was performed to compare various visual function parameters including the final visual acuity outcome and/or adverse events between corneal refractive surgery (CLRS) and phakic intraocular lens implantation (p-IOLi) in the treatment of refractive amblyopic children.
DATA SOURCESTwo reviewers independently searched the PubMed, EMBASE, and Controlled Trials Register databases for publications from 1991 to 2013.
STUDY SELECTIONThere were 25 articles, including 597 patients and 682 eyes, was included in CLRS group. Among them, 21 articles reported the use of CLRS in the treatment of myopic anisometropia for 318 patients (13 photorefractive keratectomy or laser epithelial keratomileusis and eight laser in situ keratomileusis). And 11 articles had the results of CLRS in treating hyperopic anisometropic amblyopia children. Eleven articles reported the effect of p-IOLi for treating high myopia or anisometropic amblyopia, including 61 patients (75 eyes). Age, pre- and postoperation best-corrected vision acuity (BCVA), and spherical equivalent (SE) were compared in CLRS and p-IOLi groups.
RESULTSThe average age of CLRS group and p-IOLi group has no statistically significant difference. The SE in CLRS group for myopic anisometropia amblyopia patients was (-10.13 ± 2.73) diopters (D) and for hyperopic anisometropia amblyopia patients was (5.58 ± 1.28) D. In p-IOLi group the SE was (-14.01 ± 1.93) D. BCVA was improved significantly in both groups, and even better in p-IOLi group. Refractive errors were corrected in both groups, but there was no clinically significant difference in final SE between each group. More than one-half of the children had improved binocular fusion and stereopsis function in both groups.
CONCLUSIONSBoth CLRS group and p-IOLi group showed their advantage in treating refractive amblyopia in children. In comparing p-IOLi with CLRS for treatment of refractive amblyopia, no statistically significant difference in final BCVA was observed.

PURPOSE: Cornelia de Lange syndrome is a rare disease showing characteristic facial appearance, developmental delay, growth retardation, low birth weight, skeletal formation anomaly, hirsutism and various ophthalmologic problems. METHODS: We experienced a case of an 18-year-old female with Cornelia de Lange syndrome showing superficial keratitis with entropion, ptosis, high myopia, lacrimal cutaneous fistula and characteristic facial appearance. She was born with low birth weight, operated for cleft palate and diagnosed with ventricular septal defect. In addition, she showed psychological lag and developmental impairment. RESULTS: We performed entropion correction surgery, administered medical therapy for superficial keratitis and prescribed glasses for her myopia. CONCLUSIONS: This is the first case report on the successful correction of entropion with Cornelia de Lange syndrome in Korea.

We report a case of one sister and brother with mirror image myopic anisometropia. One sister and brother complained visual disturbance. The sister was 10 years 11 months old, and brother was 8 years 4 months old. Full ophthalmic examinations were performed, including slit lamp examination, intraocular pressure, keratometry, anterior chamber depth, axial length, fundus examination and the cycloplegic refraction. The cycloplegic refractive power was -15.50 dpt cyl.+4.50 dpt Ax 85degrees (right eye), -1.00 dpt cyl.+0.50 dpt Ax 90degrees (left eye) in the sister; -1.75 dpt cyl.+2.25 dpt Ax 90degrees (right eye), -9.50 dpt cyl.+4.00 dpt Ax 80degrees (left eye) in the brother. The co-occurrence of severe myopic anisometropia in a sister and brother is extremely rare. The present case suggests that severe myopic anisometropia may be related by genetic inheritance.

PURPOSE: To evaluate the clinical characteristics of newly diagnosed glaucomatous subjects who had a history of refractive corneal ablation surgery (RCAS). METHODS: Sixty-eight glaucomatous subjects who had a history of RCAS and 68 age- and visual field (VF) mean deviation-matched glaucomatous subjects with no history of RCAS were included. Intraocular pressure (IOP), central corneal thickness (CCT), VF, and retinal nerve fiber layer thickness determined by optical coherence tomography were assessed. Parameters were compared between patients with and without a history of RCAS. Between-eye comparisons in the same participant (more advanced vs. less-advanced eye, in terms of glaucoma severity) were performed in the RCAS group. RESULTS: With similar levels of glaucoma severity, those with a history of RCAS showed significantly lower baseline IOP and a thinner CCT than the eyes of individuals without a RCAS history (13.6 vs. 18.7 mmHg, 490.5 vs. 551.7 micrometer, all p < 0.001). However, the extent of IOP reduction after anti-glaucoma medication did not significantly differ between the two groups (17% vs. 24.3%, p = 0.144). In the between-eye comparisons of individual participants in the RCAS group, the more advanced eyes were more myopic than the less-advanced eyes (-1.84 vs. -0.58 diopter, p = 0.003). CONCLUSIONS: Eyes with a history of RCAS showed a similar level of IOP reduction as eyes without such a history after anti-glaucoma medication. Our finding that the more advanced eyes were more myopic than the less-advanced eyes in the same participant may suggest an association between glaucoma severity and myopic regression.

PURPOSE: The purpose of this multi-institute, single-group clinical trial was to evaluate the effectiveness and safety of toric orthokeratology lenses for the treatment of patients with combined myopia and astigmatism. METHODS: A total of 44 patients were included in this clinical trial. The patients ranged in age from 7 to 49 years, with myopia of -0.75 to -6.0 diopters (D) and astigmatism of 1.25 to 4.0 D. After excluding 21 subjects, 23 subjects (39 eyes) were analyzed after toric orthokeratology lens use. The subjects underwent ophthalmologic examination after 1 day and 1, 2, 3, and 4 weeks of wearing overnight toric orthokeratology lenses. RESULTS: A total of 19 subjects (31 eyes) completed the trial after five subjects (eight eyes) dropped out. In the patients who completed the study by wearing lenses for 4 weeks, the myopic refractive error decreased significantly by 2.60 ± 2.21 D (p < 0.001), from -3.65 ± 1.62 to -1.05 ± 1.64 D. The astigmatic refractive error were also significantly decreased by 0.63 ± 0.98 D (p = 0.001), from 2.07 ± 0.83 to 1.44 ± 0.99 D. The mean uncorrected and corrected visual acuities before wearing the lenses were 2.14 ± 0.80 logarithm of the logMAR (logMAR) and 0.05 ± 0.13 logMAR, respectively, which changed to 0.12 ± 0.30 logarithm of the logMAR (p < 0.001) and 0.01 ± 0.04 logMAR (p = 0.156) after 4 weeks. No serious adverse reactions were reported during the clinical trial. CONCLUSIONS: Our results suggest that toric orthokeratology is an effective and safe treatment for correcting visual acuity in patients with combined myopia and astigmatism.

INTRODUCTIONThis study aimed to evaluate the proportion of young patients with type 1 diabetes mellitus (T1DM) who have myopia, as well as the risk factors associated with myopia in this group.
METHODSIn this cross-sectional study, patients aged < 21 years with T1DM for ≥ 1 year underwent a comprehensive eye examination. Presence of parental myopia, and average hours of near-work and outdoor activity were estimated using a questionnaire. Annualised glycosylated haemoglobin (HbA1c), defined as the mean of the last three HbA1c readings taken over the last year, was calculated. Multivariate analysis using genetic, environmental and diabetes-related factors was done to evaluate risk factors associated with myopia.
RESULTSOf the 146 patients (mean age 12.5 ± 3.6 years) recruited, 66.4% were Chinese and 57.5% were female. Myopia (i.e. spherical equivalent [SE] of -0.50 D or worse) was present in 96 (65.8%) patients. The proportion of patients with myopia increased from 25.0% and 53.6% in those aged < 7.0 years and 7.0-9.9 years, respectively, to 59.2% and 78.4% in those aged 10.0-11.9 years and ≥ 12.0 years, respectively. Higher levels of SE were associated with lower parental myopia (p = 0.024) and higher annualised HbA1c (p = 0.011).
CONCLUSIONCompared to the background population, the proportion of myopia in young patients with T1DM was higher in those aged < 10 years but similar in the older age group. Myopia was associated with a history of parental myopia. Environmental risk factors and poor glycaemic control were not related to higher myopia risk.

9.Intravitreal ranibizumab for the treatment of pathological myopia associated with choroidal neovascularization in Chinese patients.
Chinese Medical Journal 2014;127(16):2906-2910
BACKGROUNDPathological myopia (PM) is the leading cause for choroidal neovascularization (CNV) in people below 50 years of age, the anti-vascular endothlial growth factor (VEGF) medicine is now available to treat CNV secondary to PM. This study aimed to observe the efficacy of intravitreal ranibizumab for PM associated with subfoveal or juxtafoveal CNV in Chinese patients.
METHODSFifty-four eyes of 52 consecutive patients were included, they treated with intravitreal ranibizumab 0.5 mg for PM associated with CNV. The best corrected visual acuity (BCVA) of Snellen chart, letters of ETDRS chart, retinal thickness, leakage of CNV lesion, and complications with surgery were analyzed pre- and post-treatment. Eligibility criteria included diopter ≥-8.0 D or eye axis ≥ 28 mm with fundus changes of PM (lacquer crack, optic disc atrophy, chorioretinal atrophy, posterior scleral staphyloma); CNV secondary to PM; subfoveal or juxtafoveal CNV.
RESULTSFor 54 affected eyes of 52 consecutive patients, the average BCVA of Snellen chart and letters of ETDRS chart were 0.29 and 30.4, respectively; fundus fluorescein angiography (FFA)/indocyanine green angiography (ICGA) showed CNV leakage, and average retinal thickness on optical coherence tomography (OCT) was 267.2 µm before treatment. Injections of ranibizumab ranged from 1 to 4 (mean 2.2). Follow-up time varied from 12 to 36 months (mean 31.9 months). At the last visit, the BCVA of Snellen chart was increased by three lines (mean 0.65) (P < 0.01); the letters of ETDRS chart were increased to 17.0 letters (mean 47.4, P < 0.01); the visual acuity increased more than 15 letters in 30 eyes (55.5%), decreased in 1 eye (1.9%); the retinal thickness on OCT images was decreased by 17.0 µm (mean 250.2 µm) (P = 0.082); no active leakage from the CNV lesion occurred in 18 eyes (33.3%), reduced leakage in 30 eyes (55.6%), and no change in 6 eyes (11.1%) as shown by FFA/ICGA. Increased retinoschisis was observed in one eye after the second injection.
CONCLUSIONSIntravitreal ranibizumab for neovascular PM was well tolerated in Chinese patients, with functional and anatomic improvements in a short-term study, while a long-term study is still needed.

PURPOSE: To determine the influence of clinical features and Indocyanine green (ICG) angiographic features on the visual outcome of patients with myopic sub-foveal choroidal neovascularization (CNV) who received photodynamic therapy (PDT). METHODS: Thirty-six consecutive patients (39 eyes) with myopic CNV who were followed up for more than one year after PDT were enrolled in this study. Clinical features included age, gender, refractive error, great linear dimension, and subretinal hemorrhage. ICG features included the lesion size, lacquer cracks, hypofluorescence surrounding the CNV (dark rim), peripapillary atrophy size, and visible prominent choroidal veins under the macula. Linear regression analysis was performed using the change in visual acuity (delta logMAR) as the dependent variable and the above factors as independent variables. RESULTS: At one-year follow-up after PDT, a younger age (p=0.002) and the presence of a dark rim (p=0.002) were significantly correlated with an improvement of visual acuity (decrement in logMAR) after PDT. Other factors had no significant influence on changes in visual acuity. CONCLUSIONS: Younger patients and patients with a dark rim on ICG angiography had a higher chance of visual improvement after PDT in myopic CNV.
