RESUMO
AIM: To study the perception of first-order grating acuity and second-order spatial contrast sensitivity in patients with monocular anisometropia amblyopia.METHODS:A total of 715 children(715 eyes)diagnosed as monocular anisometropia amblyopia in our hospital from January 2018 to December 2022 were collected as amblyopia group, and 745 children(745 eyes)with normal corrected visual acuity were collected. The best corrected visual acuity(BCVA), first-order grating acuity and/or second-order spatial contrast sensitivity were measured, repectively. The perception ability of amblyopia patients to first-order grating acuity and second-order spatial contrast sensitivity were analyzed.RESULTS:There were significant differences between amblyopia group and normal control group in the perception of first-order grating acuity(11.58±6.10 vs. 20.27±3.47, P<0.001)and second-order spatial contrast sensitivity(0.33±0.16 vs 0.12±0.04, P<0.001). And there were significant differences between mild-to-moderate amblyopia and severe amblyopia patients in first-order grating acuity(12.10±6.23 vs. 8.13±3.70, P<0.001)and second-order spatial contrast sensitivity(0.32±0.16 vs. 0.37±0.17, P<0.05).CONCLUSION: The first-order and second-order visual pathway of the cerebral cortex in children with monocular anisometropia amblyopia have different degrees of damage. The injury of severe amblyopia is more serious than that of mild-to-moderate amblyopia.
RESUMO
AIM: To evaluate the efficacy of phacoemulsification with intraocular lens implantation(PEI)combined with goniosynechialysis(GSL)and goniotomy(GT)under direct vision with gonioscope in the treatment of advanced primary angle-closure glaucoma(PACG)combined with cataract.METHODS: Retrospective case series study. A total of 62 patients(65 eyes)with advanced PACG combined with cataract who were treated in the Second Hospital of Anhui Medical University from December 1, 2021 to March 31, 2023 were enrolled, and they were divided into two groups according to different surgical methods. The control group(32 cases, 33 eyes)received PEI+GSL, whereas the observation group(30 cases, 32 eyes)received PEI+GSL+GT. The intraocular pressure(IOP), best corrected visual acuity(BCVA)and the number of anti-glaucoma medications of the two groups before surgery and at 1 d, 1 wk, 1, 3, and 6 mo after surgery were evaluated. In addition, the visual field, cup-to-disc ratio(C/D), angle open range, anterior chamber depth, and average thickness of retinal nerve fiber layer(RNFL)were evaluated before and 6 mo after surgery.RESULTS: There were significant differences in IOP and lowering range of average IOP at 6 mo between the PEI+GSL+GT group(16.68±2.65, 11.12±8.53 mmHg)and the PEI+GSL group(18.71±2.51, 8.32±4.17 mmHg; P<0.05), and there was no difference in the rate of IOP reduction(44.57%±21.79% and 35.20%±17.94%, P>0.05). The number of anti-glaucoma medications, BCVA, anterior chamber depth, and angle closure range were improved in the two groups at 6 mo after operation(all P<0.01). The number of medication reductions and the range of angle opening at 6 mo after surgery in the PEI+GSL+GT group were significantly higher than those in the PEI+GSL group(P<0.05), and there was no difference in the other indicators between the two groups(all P>0.05). There was no difference in the mean deviation of visual field, C/D and average thickness of RNFL between the two groups at 6 mo after operation compared with those before operation(all P>0.05). The complete surgery success rate of the PEI+GSL+GT group was 81%(26/32), and the conditional success rate was 94%(30/32); while those rates of the PEI+GSL group were 58%(19/33)and 76%(25/33), respectively. There were statistical significance in the success rate of surgery between the two groups(complete success rate χ2=4.275, P=0.039; conditional success rate χ2=4.040, P=0.044). No vision-threatening complications and another surgery occurred in either group.CONCLUSION: The study showed that for patients with advanced PACG with cataract, PEI+GSL+GT is more effective than PEI+GSL.
RESUMO
Juxta-papillary duodenal diverticula (JPD) may easily cause biliary and pancreatic diseases. JPD changes papillary position and shape and increases the difficulties in endoscopic retrograde cholangiopancreatography (ERCP) intubation and stone removal, and it may also cause a series of complications. With reference to related articles in China and foreign countries, this article briefly describes the typing and development of JPD and its association with biliary and pancreatic diseases, analyzes the influence of common bile duct stones and JPD on ERCP, and summarizes related coping strategies, in order to provide suggestions and bases for clinical diagnosis and treatment.
