Purpose: To describe autogenous fascia lata graft fixation as a novel method to treat exotropia related to medial rectus (MR) muscle injury following functional endoscopic sinus surgery.

Methods: Three consecutive patients with MR transection and exotropia after functional endoscopic sinus surgery were selected. Preoperative examination was performed; no MR function was noted for over 3 months after injury.

We report the ocular findings in a 2.5-year-old girl with a history of congenital erosive and vesicular dermatosis at birth. We highlight the complexity of the associated nasolacrimal duct obstruction with canalicular scarring and review the ocular manifestations of this rare disease.

Background: Esotropic overcorrection on postoperative day 1 after surgery for intermittent exotropia is generally thought to increase the likelihood of long-term satisfactory alignment; however, it is unclear why some patients who are initially overcorrected demonstrate recurrent intermittent exotropia whereas others maintain esotropic to orthotropic alignment.

Methods: The records of all patients who underwent primary surgical correction of intermittent exotropia were reviewed; those with any degree of esotropia on postoperative day 1 were included. The status at the last visit was categorized as orthotropic to <8(Δ) exotropia or having recurrent exotropia >8(Δ), monofixational esotropia <10(Δ), or esotropia >10(Δ).

Article Synopsis
  • The study investigated the impact of recombinant human osteogenic protein-1 (rhOP-1) on the incorporation of cortical allografts in a canine bone defect model, where a 4 cm segment of the femur was replaced with a structural bone allograft.
  • The results showed that allografts treated with rhOP-1 had a significantly larger periosteal callus area and increased bone porosity, indicating enhanced remodeling activity.
  • No significant differences were observed in mechanical load-bearing capabilities between rhOP-1 treated and non-treated allografts, suggesting that while rhOP-1 promotes remodeling, it does not negatively affect the allograft’s strength.

The effects of a pulsed electromagnetic field (PEMF) on late bone healing phases using an osteotomy gap model in the canine mid-tibia were investigated. A transverse mid-diaphyseal tibial osteotomy with a 2-mm gap was performed unilaterally in 12 adult mixed-breed dogs and stabilized with external fixation. Animals in the variable group (n = 6) were treated with PEMF for 1 h daily starting 4 weeks after surgery for a total of 8 weeks, whereas no stimulation signal was generated in the control group (n = 6).
