PurposeTo assess the accuracy of the Plusoptix A09 photoscreener in detecting amblyopia risk factors in children and determine referral criteria when using Plusoptix A09 for a large-scale vision screening.MethodsPediatric patients attending our eye clinic underwent a comprehensive ophthalmic examination that included photorefraction, orthoptic examination, anterior segment assessment, fundus examination and cycloplegic retinoscopy. The measurements were collected for statistical analyses.ResultsOne hundred and seventy-eight children (mean age ± SD: 6.2±2.4 years, range: 2.2 to 14.1 years) were included in the study. The mean spherical equivalent (SE) obtained using Plusoptix A09 (PSE) was 0.57 D lower than that obtained from cycloplegic retinoscopy (CRSE) (P = 0.00). However, there was no statistically significant difference of Jackson cross cylinder J0 and J45 between Plusoptix A09 (PJ) and cycloplegic retinoscopy (CRJ) (P = 0.14, P = 0.26). The relationship of SE obtained from Plusoptix A09 and SE obtained from cycloplegic retinoscopy was presented as the equation: CRSE = 0.358 + 0.776 PSE + 0.064 PSE
2 + 0.011 PSE
3. Based on the Receiver Operating Characteristic (ROC) curve, the Plusoptix A09 had an overall sensitivity of 94.9% and specificity of 67.5% for detecting refractive amblyopia risk factors. The sensitivity and specificity of the Plusoptix A09 for detection of strabismus were 40.7% and 98.3%, respectively; detection of amblyopia and/or strabismus was 84.7% and 63.2%, respectively.ConclusionsThe Plusoptix A09 photoscreener underestimated hyperopia and overestimated myopia according to SE when compared with cycloplegic retinoscopy. The accuracy of the Plusoptix A09 in detecting amblyopia risk factors in children could be improved by the regression equation and optimized criteria for refractive amblyopia risk factors developed in the present study. Moreover, the Plusoptix A09 photoscreener is not suitable for a large-scale strabismus screening when it is applied solely.
Low-concentration hydrocortisone enhances the expression and function of TLRs in HCEC and provides evidence for a novel function of glucocorticoids in innate immunity.
Purpose: Vogt-Koyanagi-Harada (VKH) is an autoimmune disease with bilateral granulomatous uveitis and various systemic manifestations. Bilateral acute angle closure glaucoma (AACG) can be a rare initial manifestation of VKH that may be misdiagnosed as primary angle closure glaucoma (PACG). Case report: A 62-year-old woman with bilateral painless loss of vision referred to Qingdao Municipal Hospital. She had been diagnosed as PACG before admission and prescribed with anti-glaucoma treatment which did not improve her symptom. She had severe bilateral uveitis, optic disk swelling, and serous retinal detachment in both eyes. Intraocular pressure (IOP) was 20 mmHg in the right eye and 23 mmHg in the left eye, and her best corrected visual acuities (BCVAs) were 0.02 in both eyes. She was treated with oral corticosteroid therapy on a tapering schedule. One month after the therapy, the IOP remained well-controlled with deepened anterior chamber. Her visual acuity and symptom were improved. Conclusions: We experienced a case of VKH disease with an unusual presentation of bilateral secondary AACG. It is important for ophthalmologists to know about this rare cause of painless loss of vision so that it could be treated properly.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
