Many general conditions have an impact on the fundus. The purpose of our\nwork was to study the epidemiological profile of patients referred to our service\nfor a review of the fundus and analyze the results. It was a retrospective\nstudy description of the examinations of the fundus during the period from\nJanuary 2016 to December 2017. In the ophthalmology department of the\nLome University Hospital Center, during the study period, 1019 consultations\nwere recorded, of which 727 were for fundus 6.84%. There were 336\nmen and 391 women, a sex ratio of 0.85. The age group 40 - 69 years accounted\nfor 61.9%. The frequency of the main reasons for the request was\nhypertension 54.2% (N = 394); hypertension complicated or associated with\nother conditions (CKI, CKD, pregnancy and diabetes) accounted for 21.6%\n(N = 157), headache associated with a decrease in visual acuity 8.25% (N =\n60), diabetes 6.46% (N = 47) and sickle cell disease 0.69% (N = 5). Hospitalized\npatients 52.41% (N = 381). The fundus was abnormal in 546 patients or\n75.11%. Hypertensive retinopathy was found 80.21% cases in hypertensive\npatients, diabetic retinopathy 43.42 in diabetic patients. Diabetics Fundus\nexamination in hospital practice found a retinal lesion in three-quarters of\ncases. It so important to ask the examination of the fundus most often in the\ncurrent pactise....
Background: To evaluate the correlating and predicting factors of visual outcome after implantation of newly\ndeveloped diffractive quadrifocal intraocular lens (IOL).\nMethods: A retrospective longitudinal study was conducted. Patients who underwent diffractive quadrifocal IOL\nimplantation with a follow-up period longer than six months and records of wavefront aberrometer within one\nweek perioperatively were enrolled. Accordingly, a total of 73 eyes from 73 patients were included. The\npostoperative distance and near visual acuity, ocular aberrations and postoperative symptoms were collected. The\ncorrelation and predictability between ocular aberrations and the postoperative visual outcome were evaluated.\nResults: The corrected distance visual acuity (CDVA) one month postoperatively was significantly better than the\npreoperative status, and insignificant improvement was found six months postoperatively. Preoperative Tracey\nrefraction spherical equivalent (TRSE), angle alpha, and spherical aberration (SA) were significantly correlated with\npostoperative CDVA and near corrected visual acuity (NCVA). For postoperative ocular aberrations, TRSE, angle\nalpha, and SA were significantly correlated with CDVA six months postoperatively and NCVA, while the trefoil,\ninternal higher order aberration (HOA) and total HOA were associated with NCVA. Preoperative angle alpha could\npredict all postoperative visual performances, while postoperative TRSE and angle alpha could predict the CDVA six\nmonths postoperatively and NCVA. A large angle alpha is associated with visual disturbance and dissatisfaction.\nConclusion: The angle alpha preoperatively and postoperatively was correlated with the postoperative vision and\ncould predict visual outcome in patients who had diffractive quadrifocal IOL implanted. Furthermore, the majority\nof ocular aberrations were also associated with certain postoperative vision....
Background: Horizontal eye movements have been proposed to induce biomechanical stress and strain on optic\nnerve head. Since strabismus may lead to sustained adduction or abduction, we investigate the effects of long\nlasting unilateral horizontal strabismus on the morphology of optic disc.\nMethods: The observational cross-sectional study included patients with unilateral constant horizontal strabismus\nlasting for more than two years. The patients underwent an ophthalmological examination including refraction and\nmorphometry of the optic nerve head. A prism cover test using right angle glass prism was performed to measure\nthe magnitude of the ocular deviation.\nResults: The study included 70 patients with a unilateral constant strabismus (35 esotropic patients, 35 exotropic\npatients) with a mean age..................................
Background: To evaluate the clinical outcomes of extended depth of focus (EDOF) and monofocal intraocular\nlenses (IOLs) that share identical aspheric platform and compare their visual acuity tolerance to postoperative\nrefractive errors.\nMethods: This non-randomized, prospective comparative study included 120 eyes undergoing cataract surgery\nwith implantation of either Tecnis ZCB00 IOL (Abbott Medical Optics Inc., Santa Ana, CA) (monofocal group: 60 eyes\nof 30 patients) or Tecnis Symfony IOL (Abbott Medical Optics, Inc.) (EDOF group: 60 eyes of 30 patients). Monocular\nand binocular visual outcomes, changes in refraction, defocus curve, contrast sensitivity, and perception of photic\nphenomena (Halo & Glare Simulator; Eyeland Design Network, Vreden, Germany) were evaluated 3 months\npostoperatively. To compare the refractive tolerance, each group was divided into three subgroups according to\nthe postoperative uncorrected distance visual acuity (UDVA) and postoperative spherical equivalent (SE).\nResults: In the EDOF group, the mean 3-months postoperative monocular UDVA, intermediate (UIVA), and near�����.....
Background: To evaluate the efficacy of epiretinal membrane removal in patients with good best-corrected visual\nacuity (BCVA) for improving visual function and quality of life (QOL).\nMethods: This prospective case study compared 37 subjects with preoperative BCVA............................
Background: With the diabetes mellitus (DM) prevalence increasing annually, the human grading of retinal images\nto evaluate DR has posed a substantial burden worldwide. SmartEye is a recently developed fundus image\nprocessing and analysis system with lesion quantification function for DR screening. It is sensitive to the lesion area\nand can automatically identify the lesion position and size. We reported the diabetic retinopathy (DR) grading\nresults of SmartEye versus ophthalmologists in analyzing images captured with non-mydriatic fundus cameras in\ncommunity healthcare centers, as well as DR lesion quantitative analysis results on different disease stages.\nMethods: This is a cross-sectional study. All the fundus images were collected from the Shanghai Diabetic Eye\nStudy in Diabetics (SDES) program from Apr 2016 to Aug 2017. 19,904 fundus images were acquired from 6013\ndiabetic patients. The grading results of ophthalmologists and SmartEye are compared. Lesion quantification of\nseveral images at different DR stages is also presented.\nResults: The sensitivity for diagnosing no DR, mild NPDR (non-proliferative diabetic retinopathy), moderate NPDR,\nsevere NPDR, PDR (proliferative diabetic retinopathy) are 86.19, 83.18, 88.64, 89.59, and 85.02%. The specificity are\n63.07, 70.96, 64.16, 70.38, and 74.79%, respectively. The AUC are PDR, 0.80 (0.79, 0.81); severe NPDR, 0.80 (0.79, 0.80);\nmoderate NPDR, 0.77 (0.76, 0.77); and mild NPDR, 0.78 (0.77, 0.79). Lesion quantification results showed that the\ntotal hemorrhage area, maximum hemorrhage area, total exudation area, and maximum exudation area increase\nwith DR severity.\nConclusions: SmartEye has a high diagnostic accuracy in DR screening program using non-mydriatic fundus\ncameras. SmartEye quantitative analysis may be an innovative and promising method of DR diagnosis and grading....
