Teaching of the lateral tarsal strip technique using a duct tape simulation
Canadian Journal of OphthalmologyVol. 57Issue 4e120Published online: August 2, 2021- Jean-Philippe Rozon
- Laurence Bussières
- Daniel Ovid Black
Cited in Scopus: 0A lateral tarsal strip is a surgical procedure commonly used in oculoplastics for the repair of entropion and ectropion. A lateral tarsal strip involves correction of horizontal lid laxity with incision at the lateral canthus. Residents may have difficulties with suture placement of the tarsal strip in the periosteum. In an effort to facilitate the surgical teaching of this technique, we propose a straightforward surgical simulation to reproduce the technique. A plastic skull model, standard duct tape, surgical instruments, and suture are needed. - Photo Essays

Cited in Scopus: 1Scleral needling technique is a novel, safe, and simple alternative to suturing for effectively securing leaking sclerotomies in microincision vitrectomy surgery. After air–fluid exchange and trocar cannula removal (A), air bubbles are visualized at the site of wound leakage by dripping balanced salt solution over the open sclerotomy (B). A closed 30-gauge needle syringe is perpendicularly inserted full thickness through the sclera adjacent to the scleral opening and removed immediately (C). The wound is then pressed with a blunt cannula. - Photo Essays

Cited in Scopus: 0An 81-year-old woman presented for a routine follow-up of her dry age-related macular degeneration (Fig. 1A). She had normal eye balance and no history of strabismus. Optical coherence tomography (OCT) radial scan, using Triton OCT (Topcon, Tokyo, Japan), showed a round area behind the sclera, slightly inferior to the macula in her right eye (Fig. 1B, 1C). The vertical cuts (Fig. 1D) showed its fascicular organization. The morphology and position suggest that this structure was the inferior oblique muscle. - PHOTO ESSAY

Cited in Scopus: 0A 6-year-old girl presented with decreased vision in the right eye detected during a school-screening program. The best-corrected visual acuity was 20/120 in the right eye and 20/20 in the left eye. On retro-illumination, there were petal-shaped opacities arranged in a flower-like pattern. Prominent embryonic suture lines separating the petals completed the “floriform” pattern. A peripheral circular zone of lenticular haze with a few spokes or “riders” was also present. She was diagnosed as having a floriform cataract, a rare subtype of congenital cataract with an autosomal dominant inheritance. - Photo Essays

Cited in Scopus: 1Capsular delamination or true exfoliation of the lens is a relatively rare disorder and describes a condition in which there is a thin, fluttering capsular membrane on the anterior surface of the lens. Slit-lamp microscopy of an 81-year-old man shows localized superior iridoschisis and dense cataract with a circular scrolled leaf of the anterior capsule floating in the anterior chamber (Fig. 1A). The intraocular pressure was 23 mm Hg. Anterior segment image of swept-source optical coherence tomography clearly shows the splitting of the superficial lamella with an attached floating flap waving in the anterior chamber (Fig. - Photo Essay

Cited in Scopus: 1A 30 year-old female was hit in the left eye with a toy, resulting in a hyphema. Blood was noticed to be trapped in Berger's space (potential space between the lens and vitreous) as the hyphema cleared (Fig. 1). Surprisingly, the visual axis was spared despite the boat-shaped hemorrhages seen on retroillumination, and vision had improved from 20/150 to 20/25. No retinal tears nor detachments were found. Berger's space blood is considered to be a type of vitreous hemorrhage. With a clear traumatic cause and symptom improvement, this patient was observed. - Photo Essay
