Purpose. To evaluate the distribution pattern and changes of strabismus surgery in children based on the data collected from a local eye hospital in the south of China between 2006 and 2011. Methods. A retrospective analysis of all strabismus surgeries in children (<18 years) performed in the Eye Hospital of Wenzhou Medical University between 2006 and 2011 using the integrated information system. Result. A total of 2,219 strabismus surgeries were performed during the study period, with concomitant exotropia (44% of all surgeries) more than esotropia (27%, χ (2) = 42.7, p < 0.001). Total number of surgeries increased from 250 in 2006 to 508 in 2011, with a significant increase in concomitant exotropia: 38% of all surgeries in 2006 increased to 47% in 2011 (χ (2) = 29.4, p < 0.001). The increase of intermittent exotropia was approximately 26% of all increments of strabismus surgery between 2006 and 2011. Conclusion. Surgery for childhood exotropia was more frequent than esotropia in China. The proportion of exotropia progressively increased, while the proportion of esotropia decreased during these years. Intermittent exotropia was the main increment of strabismus surgery. Further population-based studies are needed to confirm the proportion of surgery and whether the incidence of strabismus surgery increased in China.

Ocular coloboma is a developmental structural defect of the eye that often occurs as complex ocular anomalies. However, its genetic etiology remains largely unexplored. Here we report the identification of mutation (c.331C>T, p.R111C) in the IPO13 gene in a consanguineous family with ocular coloboma, microphthalmia, and cataract by a combination of whole-exome sequencing and homozygosity mapping. IPO13 encodes an importin-B family protein and has been proven to be associated with the pathogenesis of coloboma and microphthalmia. We found that Ipo13 was expressed in the cornea, sclera, lens, and retina in mice. Additionally, the mRNA expression level of Ipo13 decreased significantly in the patient compared with its expression in a healthy individual. Morpholino-oligonucleotide-induced knockdown of ipo13 in zebrafish caused dose-dependent microphthalmia and coloboma, which is highly similar to the ocular phenotypes in the patient. Moreover, both visual motor response and optokinetic response were impaired severely. Notably, these ocular phenotypes in ipo13-deficient zebrafish could be rescued remarkably by full-length ipo13 mRNA, suggesting that the phenotypes observed in zebrafish were due to insufficient ipo13 function. Altogether, our findings demonstrate, for the first time, a new role of IPO13 in eye morphogenesis and that loss of function of IPO13 could lead to ocular coloboma, microphthalmia, and cataract in humans and zebrafish.

Mutation of IPO13 causes recessive ocular coloboma, microphthalmia, and cataract.

Myopia is the most common eye problem and affects an estimated 28.3% of the global population. Its incidence is increasing annually. Myopia treatment is limited to correcting visual acuity. Acupuncture is one of the main therapies in traditional Chinese medicine and includes plum-blossom needling, which has been widely used for both the prevention and treatment of adolescent myopia. We hypothesized that plum-blossom needling would be effective in treating myopia compared with a tropicamide eye drops control.

 Congenital nystagmus (CN) is a genetically and clinically heterogeneous ocular disorder that manifests as involuntary, periodic oscillations of the eyes. To date, only  and  have been reported to be responsible for causing CN. Here, we aimed to identify the disease-causing mutations and describe the clinical features in the affected members in our study.  All the subjects underwent a detailed ophthalmic examination. Direct sequencing of all coding exons and splice site regions in  and  and a mutation assessment were performed in each patient.  We found 14 mutations in 14/37 (37.8%) probands, including nine mutations in the  gene and five mutations in the  gene, seven of which are novel, including c.284G>A(R95K), c.964C>T(P322S), c.284+10T>G, c.901T>C (Y301H), and c.2014_2023delTCACCCATGG(S672Pfs12) in , and c.250+1G>C, and c.485G>A (W162) in . The mutation detection rate was 87.5% (7/8) of familial vs. 24.1% (7/29) of sporadic cases. Ten mutations in 24 (41.7%) non-syndromic subjects and 4 mutations in 13(30.8%) syndromic subjects were detected. A total of 77.8% (7/9) of mutations in  were concentrated within the FERM and FA domains, while all mutations in  were located in exons 1, 2, 4 and 6. We observed that visual acuity tended to be worse in the  group than in the  group, and no obvious difference in other clinical manifestations was found through comparisons in different groups of patients.  This study identified 14 mutations (seven novel and seven known) in eight familial and 29 sporadic patients with congenital nystagmus, expanding the mutational spectrum and validating  and  as mutation hotspots. These findings also revealed a significant difference in the screening rate between different groups of participants, providing new insights for the strategy of genetic screening and early clinical diagnosis of CN.

Intermittent exotropia (IXT) is the most common type of exotropia in China. Surgery is usually required to align the eye deviation to maintain or obtain better binocular visual function. However, there is a high rate of exodrift or recurrence in surgically treated patients. Orthoptic therapy is sometimes recommended for IXT patients after surgery. However, there is a lack of high-quality randomized controlled trials to prove that orthoptic therapy could be an effective supplement to surgical treatment for IXT patients. The main purpose of this study is to test the clinical effectiveness of orthoptic therapy in long-term stabilization of postoperative IXT patient. This report describes the design and methodology of the Intermittent Exotropia Postoperative Treatment Clinical Trial, which is the first large-sample, blank-controlled, randomized clinical trial.
