RESUMO
Hands-on resident surgical training for various ocular procedures is essential to impart good surgical skills to the budding ophthalmologists. Here in this report, we demonstrate a simple and inexpensive technique of performing extraocular muscle surgery on goats' eye. These animal eyes possess soft tissue resemblance to that of human eyes to a greater extent in terms of scleral rigidity, muscle elasticity, its width, thickness, and its insertion onto the sclera. Therefore, rectus muscle recession, resection, and plication surgeries can be performed repeatedly to improve an individual's orientation and practical experience before performing the procedure on human eyes.

A four-year-old child with a clinical diagnosis of unilateral congenital fibrosis of extraocular muscles (CFEOM) was planned for inferior and medial rectus muscle recession surgery, adjusted with the status of forced duction test. Due to pathological changes within the muscles subsequent to innervational abnormality, intraoperatively the inferior rectus muscle was pulled into two following the insertion of muscle hook. Moreover, the snapped muscle fibers could not be identified, thus further surgery was abandoned and an observation was commenced. At the end of 6 weeks, there was a significant reduction in the amount of hypotropia but clinically significant perverted convergence with esotropia necessitated further surgical intervention. A second surgical intervention consisting of medial rectus transposition to superior rectus with 3 mm recession was performed to achieve acceptable results in the primary gaze.

Gradually increasing abaxial proptosis in a middle-aged female patient revealed a large well-defined cystic lesion behind the globe extending till the orbital apex. B scan ultrasound and CT findings were favouring a diagnosis of orbital hydatid cyst. Thus as a diagnostic/curative surgical protocol, the cystic lesion was removed in total. However, intraoperative gross specimen examination was not classical of hydatid cyst, thus a further histopathological evaluation was carried out, which confirmed the diagnosis of orbital schwannoma with extensive cystic degeneration. Postoperatively the clinical course was uneventful at the end of 1 year.
