Introduction: Strabismus has been observed among family members in involved families. The study was conducted to document manifest strabismus running in generations and among siblings of strabismic patients. Methods: It was a hospital based prospective study conducted from May to November 2017. Strabismic patients with ocular deviation visiting Department of Paediatric Ophthalmology and strabismus were enrolled using specially designed proforma. Detailed ocular examinations were done and family history obtained regarding the presence of strabismus. Family tree was drawn for those with positive family history. Results: A total of 78 participants completed the study with 48.7% males. Family history of strabismus was present in 56.4%. Strabismus was present in two generations in 45.45%, in three generations in 18.2%, 1st and 3rd generation in 18.2%, 1st, 2nd and 4th generation in 4.5%  and among siblings only in 13.6%. Among those with positive family history, exotropia was present in 75% and esotropia in 25%. Among exotropes, manifest deviation was present in 47.7% and intermittent exotropia in 27.3%. Among esotropes, congenital esotropia was present in 9% and accommodative esotropia in 16%. First degree relatives were affected in 45.45% of strabismic patients among which 55% had manifest exotropia, 20% had intermittent exotropia, 15% had accommodative esotropia and 10% had congenital esotropia. Conclusions: Strabismus was found in different generations in 56.4% strabismic patients. Two generations were involved in 45.45%, three generations in 18.2%, 1st and 3rd generation in 18.2%, 1st, 2nd and 4th generation in 4.5% and siblings only in 13.6%. Genetic factors appear to be significant in strabismus in Nepalese population and it requires to be substantiated with further larger studies.

Abstract Background: Bilateral lateral rectus recession is the most common surgical treatment of intermittent exotropia in children. Success rates in previous studies differ because longer follow-up periods may change success rate as the eyes drift out with time. Initial overcorrection was thought to be appropriate management, but the preferred initial postoperative deviation has not been well quantified. Objective: To study long-term outcomes (≥3 years) of bilateral lateral rectus recession for intermittent exotropia and to evaluate factors influencing long-term success. Methods: This retrospective descriptive study reviews patients with intermittent exotropia who underwent bilateral lateral rectus recession with a minimum follow up of 3 years. Long-term motor outcome was classified as good (within 8 prism diopters (PD) of esodeviation and 10 PD of exodeviation), acceptable (exodeviation 11-20 PD), and poor (esotropia >8 PD or exotropia >20 PD). Stereoacuity testing pre- and postoperatively was used to evaluate sensory outcome. Correlation between long-term outcome and various pre- and postoperative factors were analyzed. Results: A total of 59 patients met the selective inclusion criteria. The mean age at time of surgery was 7.1 years with a mean follow-up time of 4.5 years. At the time of the last visit, 69% (41 patients) had good outcomes, 24% (14 patients) had acceptable outcomes, and 7% (4 patients) had poor outcomes. Initial postoperative ocular deviation significantly correlated with long-term outcome (P < 0.05). Mean initial postoperative ocular deviation of patients with good outcome was esodeviation 12.7 PD (range ortho to esodeviation 25 PD). In 45 patients whose stereoacuity could be assessed, 58% (26 patients) had stereoacuity improvement. Conclusion: Good long-term motor outcome can be achieved in 69% of patients following bilateral lateral rectus recession for intermittent exotropia. Initial postoperative ocular deviation correlated with long-term motor success.

Introduction: Vision therapy has been shown to be a successful treatment option for basic intermittent exotropia as long as a complete workup is performed to assess prognosis and appropriate management. Case Presentation: A 9 year old hispanic male presented to the clinic for a comprehensive exam and was subsequently diagnosed with a basic type intermittent exotropia with a V-pattern deviation. After thorough evaluation of binocular skills and accommodative function with a binocular vision evaluation, he was referred for a vision therapy program to improve fusional ranges, accommodative function, and symptoms. This program consisted of 20 sessions and significantly improved his binocular skills. Discussion: Basic intermittent exotropia can be treated in various ways. Vision Therapy is a worthwhile option. Surgical correction and overminus treatment have also been effective treatments. Assessment should include the intermittent exotropia control scale and the convergence insufficiency symptom survey. Vision therapy treatments focus on diplopia awareness, antisuppression, and fusional vergence ranges. Conclusion: Though more research is necessary, vision therapy has been proven to be a very effective treatment option in basic intermittent exotropia.
