Methods: Eighty-three eyes with open-angle glaucoma (mean age: 63.4 years, 24% male and 76% female) and 163 eyes with glaucoma suspects (mean age: 51.6 years, 38% male and 62% female) were included in a cross-sectional study. The connection between retinal nerve fiber layer (RNFL), optic disc and ganglion cell complex (GCC) reduction, and visual field losses were evaluated, and Pearson's correlation coefficients (R) was calculated. Results: A significant but mild correlation (R = 0.24; P < 0.002) was seen between functional and structural parameters in glaucoma suspects. After the classification of the patients by the Hodapp–Parrish–Anderson glaucoma grading scale, at mild glaucoma, it was established a significant correlation between SAP with temporal RNFL (R = 0314; P < 0.003) and optic disc (R = 0.36; P < 0.012). In relation to moderate glaucoma, it was found a higher correlation between temporal thinning of RNFL (R = 0.734; P < 0.005) and inferior GCC (R = 0.506; P < 0.023). At advanced glaucoma, there was a stronger correlation (R = 0.711;xz P < 0.014) between superior RNFL and optic disc with corresponding topographic SAP locations. Conclusions: There were significant correlations between RNFL, optic disc and GCC loss, and deficits on SAP that increase with the glaucoma severity. This damage could be predictive of visual field loss, the defects went from generalized to localized, and the change rates were directly related to the stage of the disease.","PeriodicalId":378703,"journal":{"name":"The Pan-American Journal of Ophthalmology","volume":"20 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1900-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"122916022","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}

Design: This is a descriptive, retrospective study and case report. Methodology: For the purpose of the case report, we searched and analyzed the literature referring to the diagnosis and treatment of ocular MG (OMG) in children. Description: A previously healthy 5-year-old girl presented to the emergency room because of sudden-onset ptosis of the right upper lid without other symptoms. Her examination demonstrated fluctuating ptosis and limitation to downgaze in the right eye. Because of the fluctuation of the ptosis, OMG was suggested, and the patient was tested with ice-pack test and neostigmine test with positive results. Treatment with pyridostigmine was initiated with a good response. Discussion: OMG has a very low incidence in pediatric patients. It is a disorder characterized by impairing neurotransmission at the neuromuscular junction that generates extraocular muscle weakness. It is important that ophthalmologists have knowledge about this disease because it is a differential diagnosis when there is a patient who has ptosis, strabismus, or limitation of movements. There are no standard diagnostic criteria for this disease; the diagnosis is based on clinical presentation and pharmacologic, serologic, and electrophysiologic tests. The treatment is based on steroids and anticholinesterase drugs. Some patients will require plasmapheresis or immunomodulators.","PeriodicalId":378703,"journal":{"name":"The Pan-American Journal of Ophthalmology","volume":"8 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1900-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128873530","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}
