Relation between binocular vision alteration and prehension movements in children: a scoping review.

PURPOSE: To investigate, map, and synthesize evidence regarding the correlation between changes in binocular vision and fine motor skills among children. METHODS: We conducted a scoping review of existing evidence, following the guidelines and checklist outlined in "Preferred Reporting Items for Systematic Reviews and Meta-Analyses - Scoping Reviews" (PRISMAScR). RESULTS: Sixteen papers were systematically included in our scoping review. A predominant focus was placed on assessing the impact of strabismus on motor skills. Most of the studies used motor test batteries for comprehensive analysis, while the remaining employed methodologies, such as questionnaires or laboratory-based tests. CONCLUSION: Vision stands as a pivotal perceptual modality essential for the optimal development of children. Alterations in visual acuity can significantly affect fine motor skills. Pediatric ophthalmology and orthoptics frequently encounter binocular vision disorders, such as amblyopia and strabismus. Our finding showed that impaired binocular vision affects fine motor skills.

Evaluation of changes in epivascular glia before and after intravitreal dexamethasone implant: An OCT pilot study.

PURPOSE: To detect changes in epivascular glia (EVG) in diabetic retinopathy after intravitreal dexamethasone implant using en face optical coherence tomography (enface OCT) and OCT angiography (OCTA) and to correlate improvements in functional and structural features. METHODS: A total of 38 eyes of 38 patients were enroled in this prospective study. They were divided into two different study groups: the first group including 20 eyes with diabetic retinopathy type 1 complicated by macular oedema and the control group including 18 eyes from 18 healthy age-matched patients. The main outcome measures were: (i) differences at baseline in the foveal avascuar zone (FAZ) area in the study group versus control; (ii) the presence of epivascular glia in the study group versus control, (iii) differences at baseline between foveal macular thickness versus control; (iv) changes in foveal macular thickness, FAZ and epivascular glia in the study group before and after intravitreal dexamethasone implant. RESULTS: At baseline FAZ area detected at OCTA was larger in the study group than in the control group, and epivascular glia was only detected in the study group. Three months after intravitreal injection of dexamethasone implant in the study group the best corrected visual acuity (BCVA) improved and central macular tickness reduced (P<0.0001). No significant differences were found in FAZ area while epivascular glia disappeared in 80% of the patients after treatment. CONCLUSIONS: Glia activation due to retinal inflammation in diabetic retinopathy (DR) can be detected on en face-OCT as epivascular glia. Intravitreal dexamethasone (DEX) implant improves both the anatomical and functional condition in the presence of these signs.

Morphovascular changes after anti-VEGF intravitreal injection for a choroidal neovascularization secondary to COVID-19 infection in a pediatric patient.

Choroidal neovascularization (CNV) is a common pathologic lesion that occurs in various chorioretinopathy. Although the incidence of CNV is quite rare in children and adolescents, these lesions have a severe impact on visual acuity and quality of life over patients' lifetime. The management of CNV in pediatric patients is challenging, clear guidelines are limited due to a lack of randomized clinical trials. However, the more promising option is the use of vascular endothelial growth factor (VEGF) inhibitors. We reported a case of recurrent idiopathic choroidal neovascularization in a healthy pediatric patient after COVID 19 infection. Optical coherence tomography angiofraphy (OCTA) showed, in a non invasive way, a choroidal neovascularization at the posterior pole including macula and superior temporal arcade in the right eye, while the left eye was unaffected. In order to inactivate the neovascularization, intravitreal injections of anti-VEGF (Lucentis-Ranibizumab 0.3 mL) were performed in the right eye. Six months after the injections BCVA of the right eye was improved from 0.7 logMAR to 0.2 logMAR. OCT-A examination did not detect any signs of attivation of the preexistent neovascularization. It is reasonable to assert that Anti-VEGF could be the main treatment in case of choroidal neovascularization in young patients after COVID 19 infection due to the high chorioretinal level of VEGF-A described in these diseases.
