Practice Patterns in the Management of Amblyopia: A Survey Study

Strabismus and postural control: a systematic review

The primary aim of this systematic review is to evaluate how postural balance and visual system are related in cross-eyed patients. The secondary goal is to assess the benefits of eye realignment on motor skills and body balance. Analyzing two different approaches: surgical or conservative, a systematic literature search was conducted using PubMed-Medline, Google Scholar and Cochrane Central in order to identify randomized controlled trials, case series and case-control studies which contained clinical evaluation of balance in strabismic patients as well as re-evaluation after surgery or conservative treatments via posturography to evaluate surface, length and mean speed of the center of pressure (CoP). A total of 11 studies were included in this review. The MINORS score is used to assess the methodological quality of the included studies, and its mean value was 12.8 for non-comparative studies and 17.5 for comparative studies. The postural balance was lower in strabismic patients compared with the control group, with statically higher value (p < 0.05) of surface, length and mean speed of the CoP in the study group. All patients show improvement in stability after surgery, as surface, length and mean speed of the CoP decreased after surgery in all the studies with statistical significance (p < 0.05).

The Assessment of YouTube Videos as a Source of Information for Amblyopia Treatment

PURPOSE

To evaluate the efficiency of YouTube videos as a source of information for the treatment of amblyopia.

METHODS

The authors searched YouTube (Google) using the keywords "amblyopia treatment" and analyzed the first 200 most relevant videos. Videos were classified as useful or misleading by two independent ophthalmologists. Videos were scored on 5-point scales to evaluate global quality, reliability, and comprehensiveness. General characteristics, viewer interactions, and sources of videos were also recorded.

RESULTS

Eighty-seven of 200 videos were appropriate to be included in the current study. Fifty videos (57.5%) were classified as useful and 37 videos (42.5%) were classified as misleading. General characteristics and viewer interactions were not significantly different between useful and misleading videos (P > .05). The mean Global Quality Score, reliability, and comprehensiveness scores were 3.64 ± 1.1, 3.02 ± 1.0, and 2.74 ± 1.2 in useful videos and 2.03 ± 0.9, 2.08 ± 0.8, and 1.62 ± 0.7 in misleading videos, respectively (P < .05). The data suggested that most of the videos uploaded by university channels or non-profit professionals were useful (79.2%), whereas most of the videos uploaded by medical advertisements or for-profit companies were misleading (59.1%).

CONCLUSIONS

The results of the current cross-sectional study demonstrated that the number of useful videos for the treatment of amblyopia was higher on YouTube. However, there was still a significant number of misleading videos (42.5%). Therefore, more videos on amblyopia treatment that have sufficient reliability, quality, and comprehensiveness should be uploaded to YouTube. [J Pediatr Ophthalmol Strabismus. 2021;58(5):311-318.].

Diagnosis and Management Practice Patterns among Pediatric Ophthalmology Personnel in Israel

PURPOSE

To investigate the diagnosis and management practice patterns of different aspects of pediatric ophthalmology among pediatric ophthalmologists and orthoptists in Israel.

METHODS

A 21-question survey was delivered to all registered pediatric ophthalmologists and orthoptists in Israel.

RESULTS

The response rate was 58.3%. Most pediatric ophthalmology personnel in Israel do not document intermittent exotropia (IXT) with a control scale, do not use modalities other than patching for amblyopia, and do not use distance stereoacuity tests. There was no consensus regarding patching and over minus treatments in IXT. In contrast to frequent use of prism adaptation test (PAT) for evaluating strabismus, most Israeli pediatric ophthalmology personnel do not use postoperation diplopia test (PODT). While most orthoptists use a questionnaire when diagnosing convergence insufficiency (CI), most pediatric ophthalmologists do not.

CONCLUSION

This study highlights the current areas of consensus and disagreement regarding pediatric ophthalmology diagnosis and management practices in Israel. Adopting a uniform approach regarding diagnosing CI, including using a questionnaire by pediatric ophthalmologists and orthoptic exercises in the management of IXT, is warranted to enable unified treatment by pediatric ophthalmologist and orthoptists in Israel.
