Objective To observe the functional and morphological changes of macular after panretinal photocoagulation（PRP）in the patients with diabetic retinopathy（DR）.Methods A total of 57 eyes of 34 patients with DR undergoing PRP were enrolled in this prospective and self-reflection study. Comparatively analyze the changes of the best visual acuity（BCVA）, optical coherence tomography (OCT) and multi-focal electroretinography (mfERG) before PRP,20 days, 3 months and more than 9 months after PRP. Statistical analyses were performed by wilcoxon, chisquare, Dunnett-t, LSD-t tests and spearman related analyses. The changes of macular function and foveal retinal thickness before and after PRP were comparatively analyzed.Results BCVA of all patients reduced at 9 months after PRP（P=0.022）.The amplitude density of mfERG P1 of ring 2 decreased at 20 days after PRP（P=0.039）,then recovered at 3 months and decreased again at 9 months（P=0.014）.The amplitude density of mfERG P1 of ring 3-5 decreased at 20 days,3 months and more than 9 months after PRP（20 days: ring 3: P=0.000,ring 4: P=0.001, ring 5: P=0.000；3 months: ring 3:P=0.000, ring 4: P=0.006, ring 5: P=0.001; more than 9 months: ring 3: P=0.000,ring 4: P=0.000, ring 5: P=0.000）. The amplitude density of mfERG P1 of ring 1 was significantly lower at 9 months after PRP（P=0.050）. The foveal retinal thickness increased at 20 days after PRP(P=0.007), then recovered at 3 months or later. Cystoid macular degeneration was found in 6 eyes(10.5%) at 20 days after PRP.Conclusions After the treatment of PRP, there were some extend reduction of the macular function, a transient increase on foveal retinal thickness. Combined mfERG and OCT can be a comprehensively and objectively assessment of macular function and morphology.
Adenoid hypertrophy in children with epilepsy is rarely reported. This paper analyzes the clinical characteristics and incidence of adenoid hypertrophy in children with epilepsy.Methods The clinical data in children with epilepsy from December 2014 to April 2020 in Shenzhen Children's hospital were analyzed retrospectively.Results There were 449 cases diagnosed with adenoid hypertrophy (2.74%) in 16387 children with epilepsy. Among 449 cases of adenoid hypertrophy, 276 males (61.47%) and 173 females (38.53%). The age distribution was: 28 days to 1 year old, 8 cases (2%); 1-3 years old, 78 cases (17%); 3-6 years old 167 cases (37%); 6-12 years old, 153 cases (34%); 12-18 years old, 43 cases (10%). In 40 patients the IgG antibody were positive for EB capsid antigen in 25 (62.5%). In 56 cases of EB virus DNA were detected by fluorescence quantitative PCR, 25 (44.64%) positive, and 21/44 cases (47.72%) were positive by general nucleic acid detection of enteroviruses. The neutrophil reduction rate in peripheral blood was 42.19% in 673 tests, lymphocyteincreased in 292 (43.38%), platelet count increased in 307 (45.61%), abnormal in platelet hematocrit in 311 (46.21%); the mean volume of RBC was decreased in319 (47.39%) tests. The content of \begin{document}${\rm{HCO}_3^-} $\end{document} was reduced in 20/55 cases (36.36%). 25-hydroxy vitamin D was 33 (44.5%) decreased in 74 cases. The blood glucose was measured in 146 cases, 60 (41.09%) increased, total cholesterol was 31 (40.78%) increased in 76 cases, serum C peptide was 12 (29.26%) increased in 41 cases.Conclusion Adenoid hypertrophy in children with epilepsy may be related to infection, inflammation or immune disorder, which may cause nutritional, metabolic or internal environment disorders. Therefore, there is need of nursing and health education, transferring to specialized centers for diagnosis and treatment.
