Unilateral recession and resection surgery with adjustable suture in adult sensory exotropia: long-term success and exotropic drift.
In conclusion, unilateral recession and resection surgery with adjustable suture in adult sensory exotropia achieved 50% success at 2 years. Initial postoperative moderate overcorrection results provide the highest chance for long-term success. The majority of patients developed exotropic drift with time and time to failure was 2 years.

Prevalence and pattern of amblyopia in a rural hospital in Ghana.
Authors: Asare AK, Akuffo KO, Kumah DB, Agyei-Manu E, Darko CK, Addo EK Abstract Amblyopia is a developmental ocular disease of childhood-onset which may lead to persistent sequelae into adulthood. Early detection and management of amblyopia usually result in an improved visual outcome. The purpose of this study was to determine the prevalence and pattern of amblyopia in a rural hospital in Ghana. Clinical records of patients seen (from January 2014 to December 2018) at Westphalian Medical Center, Oyoko, Ashanti Region, Ghana, were reviewed retrospectively. Unilateral amblyopia was defined as a two-line interocular...

Minimal invasive vertical muscle transposition for the treatment of large angle exotropia due to congenital medial rectus hypoplasia: Case Report and Literature Review.
Authors: Kiarudi MY, Sabermoghadam A, Sardabi M, Jafarzadeh SV, Razavi ME Abstract Reports of isolated anomalies of the medial rectus (MR) muscle in literature are sparse. It has been identified as a subtype of congenital cranial dysinnervation disorder that affects the normal development of brainstem motor neurons. Herein, we report a 37-year-old male presented with large-angle exotropia since the birth of right eye with palpebral fissure widening. On examination of ocular movements, there was -6 limitation of adduction. There was no limitation in other ocular movements. In the preoperative CT scan, all extraocula...

Instead of pulley bands, does retrobulbar fat keep the eye muscle bellies in place and thereby act like a pulley?
Authors: Simonsz HJ Abstract Extraocular muscle pulley bands were described by Tenon in 1805 as "faisceaux tendineux" acting as "poulies de renvoi." The Passive and Active Pulley Hypotheses propose that these connective-tissue bands between muscle and bony orbital rim limit vertical shift of the horizontal rectus muscle belly in up- and downgaze, caused by the muscle's tendency to assume the shortest path from origin to insertion. The band's attachment to the muscle moves 20 mm sagittally when the eye looks from 50° left to 50° right, however, impeding vertical muscle stabilization. Slid...

Evolving trends in strabismus following retinal surgery: is there still a role for botulinum toxin?

Interestingly, there has been a downward trend over the last decade across the United Kingdom with the evolution of refined vitrectomy techniques and instrumentation. We aim to report our updated experience on factors influencing botulinum toxin outcomes in view of the trend toward vitrectomy.Methods: The Moorfields strabismus service carried out a follow-up retrospective study of all subjects that receiv...

The impact of an eye drop booklet on distress in children when receiving eye drops.
Conclusions: At T1 and T2, the differences in the children's distress scores were not statistically significant between the booklet group and the group who did not use the booklet. Children, generally, anticipated greater discomfort than what they actually experienced during the administration of eye drops. For most children, the booklet had a positive effect on their distress levels, but not for all. A large majority of parents noticed the added value of the booklet for their child. They were very positive and wanted to continue using the booklet in the future, as it appeared to give their child a sense of control during ...

Long-term refractive outcomes in children with early diagnosis of moderate to high hyperopia.
Conclusion: In our study, children with moderate to high hyperopia did not experience a significant reduction in the power of the refractive error. Although almost 50% of children had an initial deviation, only one had amblyopia at the end of follow-up. Implementing screening strategies for the early detection of this refractive error may prevent long-term vision morbidity in hyperopic children.

We describe a rare case where an extra-large V pattern (>60 Prism Dioptres (PD)) was present along with large exotropia (70 PD). Craniosynostosis or facial asymmetry was not present. The extra-ocular motility evaluation revealed mild over-elevation in adduction and extreme divergence in up-gaze. Examination of the fundus showed ex-cyclotorsion of both the globes. The V pattern was managed by bilateral inferior oblique muscle recession and full thickness upshift of both lateral rectus muscles. The exotropia was treated by bilateral lateral rectus recession and right eye medial rectus resection. Postoperatively, both the ...

The prevalence of tropia, phoria and their types in a student population in Iran.
Conclusion: The prevalence of strabismus in university students was similar to the Iranian general population but lower than other countries. One in every 10 students had phoria, which was much lower than similar reports on Iranian populations; however, due to near-work activity, these students are prone to asthenopia, early visual fatigue, and decreased productivity. Therefore, it is suggested that university students also undergo screening programs to detect the cases of tropia and phoria. PMID: 31868064 [PubMed - as supplied by publisher] (Source: Strabismus)

Ocular ductions after rectus muscle recession and resection in thyroid eye disease.
Conclusion: In this retrospective analysis, we found an equal effect on ocular ductions in patients with TED when comparing recess/resect eye muscle surgery to recess only procedures. In TED patients with large horizontal angle deviations and abduction deficit, medial rectus recession and lateral rectus resection surgery can be considered. Muscle resections in TED do not seem to have a clinically relevant risk to increase the restriction of ocular ductions but rather improve ductions in the restricted directions of gaze.

Conclusions: The Lang Stereopad test is easy to administer and it has certain advantages such as no requirement for additional test glasses. It is a useful assessment to add to the clinical armamentarium for binocular assessment of stereopsis. The Lang Stereopad does not agree well with other stereo tests such as the TNO and Frisby but provides a greater stereoacuity test range than the Lang II.

Overall surgical success rate in our study population failed to differ significantly from a control population and were comparable to that reported in the literature. We found that compliance with treatment influenced surgical success rates in our study population. The high rate of lost to follow-up in the study population is an important factor influencing our conclusion that no difference exists between our groups.
