Treatment of symptomatic epiblepharon with Botulinum toxin type A in patients under 2years of age

INTRODUCTION

Epiblepharon is a congenital eyelid malposition due to a horizontal skin fold and a redundant orbicular muscle, resulting in the inward positioning of the eyelashes.

OBJECTIVE

Personal experience is presented of the non-surgical correction of symptomatic epiblepharon using a pretarsal injection of 5 IU of botulinum toxin type A (BoNT-A) into the orbicular muscle.

MATERIAL AND METHODS

Patients with epiblepharon younger than 2 year were included in the study. A review was made of their clinical charts and the symptoms and signs of epiblepharon were evaluated before and after treatment with BoNT-A.

RESULTS

A total of 40 patients were included (28 girls [70%]). The mean age at treatment was 11 months (range, 4-24 months). A total of 76 eyelids were treated with BoNT-A. A statistically significant improvement in symptoms, lash-corneal touch, and punctate corneal epitheliopathy were reported after the treatment with 5IU BoNT-A. The mean final follow-up was 25.5 weeks (range, 4-92 months).

CONCLUSIONS

The present study provides evidence that a pretarsal BoNT-A injection is an effective and safe treatment for the correction of symptomatic epiblepharon in patients younger than 2 years of age.

Epiblepharon correction in Korean children based on the epicanthal pathology

PURPOSE

This study aims to investigate the surgical outcomes of a novel epiblepharon correction method based on the pathologic features of epicanthal tissue. The correlation between the pathology and clinical presentations was also studied.

METHODS

This retrospective study included 72 eyelids of 36 children with epiblepharon and epicanthal folds. From July 2013 to March 2016, epicanthal tension-releasing procedure of subdermal fibrinolysis with orbicularis oculi ring myotomy were performed in 36 children. Photographs before and after operation were analyzed with Image J program. A clinical severity of the epiblepharon was scored based on the lower eyelid skin fold height (mild to severe). Subdermal fibrosis index was defined as the portion of fibrosis in low power field (× 40) and eyelid contour was assessed with custom software (MATLAB). Eighty eyelids without eyelid pathology were analyzed to establish the normal eyelid contour. The epicanthal tissues were classified into three categories: mild, moderate, and severe fibrosis.

RESULTS

The mean age of the patients was 5.5 years. Intercanthal distance (ICD) ratio was defined as Inner ICD (IICD)/outer ICD (OICD). The IICD/OICD was 0.41 in the severe epiblepharon group that is significantly longer compared to that of the mild epiblepharon group (0.38). Subdermal fibrosis index was higher in severe epiblepharon group. Eyelid contour was normalized and the cilia touch was resolved after the epicanthal tension-releasing procedure.

CONCLUSION

Epicanthal tension-releasing procedure with orbicularis oculi ring myotomy achieved favorable surgical outcomes. Clinical correlations with pathologic findings and satisfactory results of the procedure suggest that medial epicanthal fibrosis is the main pathologic feature causing epiblepharon and epicanthal folds.

Conservative Management of Lower Eyelid Epiblepharon in Children

PURPOSE

Although much literature has focused on various techniques to repair epiblepharon, no study has addressed how frequently surgical intervention is required.

METHODS

The authors tabulated data from all patients with epiblepharon seen over the past 15 years.

RESULTS

Eighty-nine patients were included, 61 (69%) with tearing, discharge, conjunctival injection, or eye rubbing. Trichiasis was present in 15 cases (17%), 6 (7%) with corneal staining. In all cases, the initial treatment was conservative: antibiotic ointment or tear substitutes in 73 cases with trichiasis, symptoms of irritation, or corneal changes and observation in the remaining 16 cases. Three children (3%) were referred for eyelid surgery because of persistent symptoms. No patient had corneal scarring or long-term complications.

CONCLUSIONS

Although vision-threatening complications can result, a trial of topical antibiotic ointment and/or ocular lubricants was effective in nearly all patients. Most resolved with minimal symptoms. The few eventually requiring eyelid surgery suffered no long-term complications. The authors recommend a trial of conservative treatment before eyelid surgery is undertaken.

Management of epiblepharon: state of the art

PURPOSE OF REVIEW

Epiblepharon is prevalent in East-Asian children. As the population in Asia is increasing, so is the demand for epiblepharon surgery. Surgeons should be familiar with the standards of beauty and needs of Asian people for epiblepharon management. This review provides a comprehensive summary of the published studies on the clinical manifestations, pathophysiology, and management of epiblepharon.

RECENT FINDINGS

Astigmatism is prevalent in epiblepharon patients, which can contribute to amblyopia. Early surgery and visual rehabilitation is important for epiblepharon patients with a high degree of astigmatism and amblyopia. Various etiologic factors play a role in the pathophysiology of epiblepharon. Surgical procedures focusing on creation of a lower eyelid crease have been popular for treating epiblepharon in Western textbooks; however, this is not appropriate for Asian patients in whom, a crease may be undesirable. In selecting surgical methods, it is important to resect a minimal amount of skin-muscle to avoid the adverse effects of ectropion and eyelid retraction.

SUMMARY

Although epiblepharon may resolve with facial growth, surgical correction is needed for cases in which there is significant corneal injury from the lash touch. Surgical management should focus on techniques that are effective, with little chance of complication, and do not create a lower eyelid crease.

Epiblepharon in Chinese children: relationships with body mass index and surgical treatment

PURPOSE

To evaluate the relationship between the incidence of lower eyelid epiblepharon and body mass index in Chinese children and report the outcomes of a rotating suture technique or the L-plasty procedure aimed at correcting the structural anomalies.

METHODS

The medical records of patients treated surgically, with either rotating suture procedure or L-plasty, for lower eyelid epiblepharon were reviewed retrospectively and compared with an age-matched control group of children without epiblepharon. Body mass index (BMI) was calculated as weight in kilograms divided by the square of height in meters.

RESULTS

A total of 67 patients (mean age, 5.7 ± 2.6 years) and 178 controls were included. All patients had coexistent epicanthus. In 62 patients, rotating suture procedures were used; in 5, L-plasty. The BMI in 4- to 6-year-old boys with epiblepharon was significantly higher than that in children without epiblepharon (P = 0 .042). All patients showed successful surgical outcomes according to improvement of symptoms and lack of cilia-cornea contact. There were no cases of recurrence or other complications.

CONCLUSIONS

Obesity may be an aggravating factor in cases of lower eyelid epiblepharon, which may be corrected effectively with the rotating suture procedure and the L-plasty procedure. The L-plasty procedure is recommended for patients with coexistent severe epicanthus.
