Objective: To detect the pathogenetic mechanism of motion-sensitive cortical deficit in response to motion stimuli in children with anisometropic amblyopia using a blood oxygenation level-dependent functional magnetic resonance imaging technique (BOLD-fMRI). Methods: This was a case series study. Patients were collected from June to December 2017 at Tianjin Eye Hospital. Twenty-five patients who were diagnosed with anisometropic amblyopia as amblyopia group and twenty-five normal volunteers were examined as control group. A BOLD-fMRI technique on a 1.5T MRI and a horizontally moving sinusoidalgrating block design were used for task conditions. All data were processed with SPM5 software, were analyzed by t test. Results: Significant fMRI activation and comparable right and left eye activation were found in the middle temporal area (MT), and Brodmann areas 19 and 37, in all control subjects; Lesser cortical activation in area MT and Brodmann areas 37, 19, and greater activation in the frontal gyrus of the lazy eye group were detected compared to the control group. Lesser cortical activation in Brodmann area 37, 18 of the contralateral eye of the amblyopic group was detected compared to the control group. Lesser cortical activation in area MT and Brodmann areas 19, 18, and greater activation in the frontal lobes of the anisometropic amblyopic eyes were detected compared to the contralateral eyes. Conclusions: The spatial extent and intensity of the visual cortex activation in the visual cortex decreases in the amblyopic eye compared to the normal control. Decreased cortical activation in the fellow eye is prevalent. A greater visual cortex area is activated when stimulating the amblyopic eye.

Objective To investigate the clinical features, treatment and prognosis of children patients with acute lymphoblastic leukemia complicated by cytomegalovirus retinitis after chemotherapy. Methods The clinical data about 17 patients (30 eyes) with acute lymphoblastic leukemia complicated by cytomegalovirus retinitis after chemotherapy who were treated in our hospital from January 2014 to September 2017 were collected to analyze retrospectively the risk factors of pathogenesis of cytomegalovirus retinitis, therapeutic method and prognosis of patients. All the patients underwent slit-lamp ophthalmoscopy, mydriasis fundus examination, color fundus photography and general physical examination including blood CMV-DNA,urine CMV-DNA and CD4+T lymphocyte counts. The patients were once suffered from cytomegalovirus retinitis, they were given systemic antiviral treatment,however, the patients who were intolerant to systemic antiviral treatment and had obvious adverse reactions or continuing progression of lesions were given antiviral drugs by intravitreal injection. Results Among 17 patients (30 eyes) with acute lymphoblastic leukemia who were diagnosed definitely as cytomegalovirus retinitis, there were 8 males (14 eyes),9 females (16 eyes),with age ranges being 5～14 tears [mean age (8. 18 ± 2. 64)years]. The lesions in 76. 5％ of patients were involved in binoculus,and 23. 5％ of patients with unilateral disease,and 13. 3％ of them were central lesions,36. 7％ were peripheral lesions,50％ were mixed lesions,30％ were involved in yellow spot,20％ were combined with optic neuritis and 40％ were with extensive retinal vasculitis. The CD4+ T lymphocyte counts were 20 ～186 cells/μl,with mean counts being (99. 66 ± 49. 1)cells/μl,which in 17. 6％ of patients were less than 50 cells/μl,17. 6％ of patients were 50～100 cells/μl,52. 9％ of patients were 100～150 cells/μl,11. 8％ of patients were more than 150 cells/μl. Moreover the retinopathy was gradually subsided in 9 patients after systemic treatment, however, the active lesion was not relieved in 6 patients after systemic antiviral therapy treatment, then the 6 patients were given ganciclovir by intravitreal injection untill the pathological changes were stopped. In addition 2 patients who did nor receive regular systemic antiviral therapy suffered from retinal detachment. Conclusion Once incidence of cytomegalovirus retinitis, the patients should be treated by systemic antiviral drugs,at the same time,cell immune function of patients should be detected. For the patients whoare intolerant to systemic treatment,with obvious adverse reactions or progression of lesions, can be treated by giving antiviral drugs through intravitreal injection to control the progression of diseases.

Objective To observe the clinical features of retinal arterial occlusion (RAO) in youth.Methods This is a retrospective case review.Nine patients (9 eyes) with RAO were enrolled in this study.There were 6 males (6 eyes) and 3 females (3 eyes).The average age was (14.22± 3.93) years.The best-corrected visual acuity (BCVA),indirect ophthalmoscopy,fundus color photography and fundus fluorescein angiography were performed.All patients underwent systemic evaluation including blood routine,erythrocyte sedimentation rate,blood lipids,vasculitis screening,homocysteine level,antiphospholipid antibody,blood coagulation,neck vascular ultrasound,and cardiac color ultrasound and electrocardiogram examination.All patients received oxygen therapy,blood medications and symptomatic treatment.Meanwhile,the patients with autoimmune diseases were received systemic glucocorticoid therapy.The follow-up was ranged from 6 to 12 months.The visual acuity and fundus change before and after treatment were compared.Results among 9 patients,one patient had systemic lupus erythematosus,one patient had congenital heart disease,one patient had hypergammaglobulinemia,and carotid artery color ultrasonography showed that the internal carotid artery vessels faltered in 2 cases.The BCVA was 0.01-0.12.Among 9 eyes,there were 5 eyes (55.6％) with retinal branch artery occlusion (BRAO),2 eyes (22.2％) with central retinal artery occlusion (CRAO),2 eyes (22.2％) with ciliary retinal artery occlusion (CLAO).CRAO eyes showed positive RAPD (relative afferent pupillary defect),fine retinal artery and the corresponding vein,pale white retinal edema in posterior area and macular cherry-red spot.BRAO eyes manifested as inferior temporal artery occlusion and pale white retinal edema around them.CLAO eyes showed temporal ligulate grey-white retinal edema.At the last follow-up,BCVA improved and retinal vessels returned to normal in 7 eyes (77.8％);BCVA unchanged and no improvement in fundus in 2 eyes (22.2％).Conclusion Adolescent RAO is mostly partial occlusion,the prognosis is generally good after early active treatment.

Objective To investigate clinical features, misdiagnosed causes and preventive measures of children with concealed corneal foreign body. Methods Clinical data for 8 misdiagnosed children with concealed corneal foreign body was retrospectively analyzed. Results The misdiagnosed rate was 17. 8% in this study, and patients' age range from 5 months to 16 years old. All children had repeatedly red-eye, and had been misdiagnosed as having keratitis, but the effects were poor by corresponding treatments. Misdiagnosed time was 3 d-2 months. Concealed corneal foreign body was confirmed by red-eye re-current attacks, corneal irritation, careful slit lamp examination and staining, and foreign body was removed. The children re-covered well after the surgery without red-eye symptom during 2 months of review. Conclusion Concealed corneal foreign body is easy to be misdiagnosed. The patients should be highly suspected as having concealed corneal foreign body with symp-toms of repeatedly red-eye symptom, photophobia, lacrimation, foreign body sensation or with corneal inflammatory infiltra-tion, ulcer turbidity, local opacity in eye examinations and long-term incurability.

Objective To investigate types of fundus change in children with acute lymphoblastic leukemia and clinical features of each type, providing the clinical basis for differential diagnosis and timing of treatment. Methods Retrospective case study. The clinical data of 24 patients (39 eyes) with acute lymphoblastic leukemia and clinical features were collected from January 2015 to September 2017. Slit-lamp ophthalmoscopy,indirect oph-thalmoscopy, fundus photography, blood CMV-IgM, blood CMV-DNA, urine CMV-DNA, and T-lymphocyte counts when the lesion changes were measured. Results 39 eyes of 24 patients are reviewed,including 15 males 25 eyes,9 females 14 eyes. The age ranges from 3 to 14 years,the mean age was (7.88±2.61) years old. In-cluding 11 cases 17 eyes (45.83%) of cytomegalovirus retinitis and 13 cases 22 eyes (54.17%) of leukemic retinopathy were included,fundus changes were the first manifestation in 4 cases. All the cytomegalovirus retinitis patients CD4+ T lymphocyte were less than 200 cells/μl. Temporal peripheral lesions are most common,the majori-ty of lesion were quiescence after treatment following with increase of CD4+ T lymphocyte count, more than 200 cells/μl. Bilateral optic disc edema appear in 45.45% of leukemic retinopathy, 36.36% has retinal hemorrhage, 18.18% has both. The prognosis was good after treatment in department of hematology. Conclusions There are vari-ous types of fundus changes in children with acute lymphoblastic leukemia and need to be identified, cy-tomegalovirus retinitis should be notice except of leukemic retinopathy. The progression of cytomegalovirus retinitis is closely related to the decrease in T-lymphocyte counts. For DNA positive and CD4+ T lymphocyte reductions, especially in patients with less than 200 cells/μl, cytomegalovirus retinitis should be highly suspected. The prognosis of fundus disease caused by leukemia is better.
