The perceived personality traits of adults with digitally induced large angle strabismus and the impact of its correction

Strabismus Surgery for Psychosocial Reasons-A Literature Review

Introduction

Strabismus surgery may be undertaken for visual benefit, to improve or eliminate diplopia symptoms, or to restore or improve binocular single vision (BSV). In patients without visual symptoms or expected visual benefit, strabismus surgery may still be undertaken if the presence of strabismus causes the patient psychosocial symptoms. To evaluate strabismus surgery undertaken for psychosocial reasons, evidence of postoperative outcomes in this specific cohort is needed.

Methods

A systematic search of the literature was conducted (1946-2023) to identify evidence where postoperative outcomes were reported for adult patients (age 18 years and above) who had undergone strabismus surgery for psychosocial reasons.

Results

Sixty-nine papers were included in the literature review. Most sources of evidence included patients within heterogeneous cohorts of strabismus surgery outcomes, with a range of symptoms and differing surgical aims.

Discussion

In adults who underwent strabismus surgery for psychosocial reasons, improved postoperative ocular alignment and/or improved health related quality of life (HRQoL) were common. Strabismus surgery outcomes appeared to be measured satisfactorily at three months postoperatively. Additional surgical outcomes, including an expanded field of vision, unexpected BSV, improved binocular summation, improved task performance and improved eye movements have been reported, but not fully investigated. There was a lack of consensus on how postoperative success should be defined and measured. A core outcome set for strabismus has been suggested and there is potential to add to the available evidence by investigating which outcome measures are most relevant to those with strabismus and psychosocial symptoms. There is a growing need for robust evidence in this specific subgroup of patients due to a lack of evidence specifically reporting postoperative outcomes in adults with strabismus and psychosocial symptoms.

Is There Gender Bias in Perceptions of Strabismus Among Adults?

PURPOSE

To investigate the effect of gender, type, and size of horizontal deviation on the perceived severity or need for intervention for strabismus among adults in the general population.

METHODS

Eight photographs of individuals aged 25 to 35 years were digitally manipulated to create 30 prism diopters (PD) of exotropia, 30 PD of esotropia, 50 PD of exotropia, and 50 PD of esotropia in both men and women. A survey asked respondents to rank these photographs by their severity or need for intervention from 1 (greatest need) to 8 (least need) to assess for unconscious bias for gender, strabismus type, or deviation size.

RESULTS

A total of 203 adult respondents completed the survey. Participants ranked men with both large esotropia and large exotropia (median rank = 1.5, interquartile range [IQR] = 1.5 to 1.5) as needing correction more urgently than similar women (median rank = 3.5, IQR = 3.5 to 4) (P < .0001). The median rank was 4 (IQR = 3.75 to 4.25) for all men combined and 5 (IQR = 4.75 to 5.25) for all women (P < .0001). Photographs with exotropia (median rank = 4, IQR = 3.75 to 4.5) were perceived as more severe than photographs with esotropia (median rank = 5, IQR = 4.5 to 5.25) (P < .0001). Respondents' gender, age, or history of strabismus did not significantly impact their rankings.

CONCLUSIONS

Male photographs were perceived as having a greater need for strabismus intervention than female photographs despite similar type and size of deviations. Exotropia was perceived as more severe than esotropia for smaller deviations only. More studies on the perceptions of strabismus are needed to understand whether unconscious bias affects patient care. [J Pediatr Ophthalmol Strabismus. 2023;60(6):396-401.].

The impact of strabismus on psychosocial heath and quality of life: a systematic review

Strabismus can hinder an individual's ability to perform daily functions and negatively affect their well-being. I examine the impact strabismus has on psychosocial health and quality of life in children and adults and evaluate the challenges confronted by parents of children with strabismus. Numerous misconceptions exist regarding the impact strabismus has on overall health. Negative attitudes persist toward those affected, resulting in difficulties with self-image. Individuals with strabismus are at increased risk for both visual system and psychiatric disorders. Misinformation regarding available treatment options for children and adults with strabismus continues to exist, resulting in decreased access to care. Improved education of health care providers can increase appropriate referrals and initiation of treatment. Treatment of strabismus is not merely cosmetic and has the potential to improve psychosocial health and quality of life for children and adults with and without diplopia.

Measuring attention bias in observers of strabismus subjects

BACKGROUND

Despite the known negative psychosocial impact and the importance of facial aesthetics for individuals with strabismus, the gaze pattern of the presumed attention bias has not been documented previously.

METHODS

Thirty images (15 digitally reconstructed color photographs to show strabismus and 15 photographs of volunteers without strabismus) were viewed in random order by 25 naïve participants (age range, 23-63 years; 15 females). Visual scan paths of participants were recorded using an infrared corneal image eye movement recorder, and the individual parameters of saccades, fixations, and dwell time were assessed using DataViewer software.

RESULTS

Viewers primarily tended to fixate on the eyes, the nose was the next most prominent point of focus (both P < 0.001). Time to first fixation and the presence of strabismus in the images presented were significantly associated (P < 0.001). When the eyes were viewed, there was more time spent looking at the strabismic eye (P < 0.001), although the number of fixations toward the eyes did not differ significantly between normal and strabismic faces (P = 0.2).

CONCLUSIONS

Our results confirm that the presence of strabismus in the features of the human face draws longer attention from the average viewer to the eye region, and particularly to the strabismic eye.

To assess knowledge and attitude of parents toward children suffering from strabismus in Indian subcontinent

Purpose:

Strabismus and anisometropia are the most common causes of amblyopia. It can be easily prevented or treated if detected early. With the changing socio-cultural-economic milieu of the society, the perspectives of strabismus in society are gradually changing but still adequate knowledge, awareness, and attitude of parents toward strabismus will help in preventing amblyopia and aid in the proper psychosocial adaptation of such children. This study aimed to assess knowledge and attitude of parents toward children suffering from strabismus.

Methods:

A prospective study was carried out from January 1 to February 29, 2016, through a structured questionnaire to assess the level of knowledge and attitude of parents of children suffering from strabismus.

Results:

One hundred and twenty parents of children with strabismus were interviewed through a questionnaire. Education level of 78 parents was less than graduation (60%) and of 42 parents (40%) was graduation or higher. The majority of the parents, i.e., 116 (96.67%) were bothered due to strabismus. One hundred and one (84.17%) parents felt that their child's strabismus was noticed by others during interaction. Seventy-four (61.67%) parents felt that their children will have difficulty in making friends. Ninety (75%) parents felt uncomfortable if someone asked something about their child's strabismus. One hundred and ten (91.67%) parents considered strabismus as cosmetic stigma.

Conclusion:

Some parents, especially from the lower educated segment, had poor understanding of strabismus, thus resulting in late presentation and ineffective countermeasures. The key to prevent strabismic amblyopia and its psychosocial impacts is to provide health education regarding strabismus.
