How to knot bury and not break the suture: the 3-1-bury-1 knot
Suturing of a wound is typically performed for incisions that fail to seal after stromal hydration or after other anterior segment procedures, such as penetrating keratoplasty.1–4 On tying a suture of appropriate tension, rotation and burying of the knot is important to prevent foreign body sensation and irritation to the palpebral conjunctiva.3–6 However, the knot can break or slip during rotation and burying of the knot.Rhodotorula endophthalmitis associated with Baerveldt shunt implantation
Endophthalmitis is an uncommon complication of glaucoma drainage device surgery.1 Most cases are secondary to Gram-positive bacteria: Staphylococcus, Streptococcus, and Haemophilis.2 Cases caused by fungal pathogens are very rare. Rhodotorula is a common environmental yeast that has recently been recognized as a human pathogen. Infections are most commonly linked to frequent intensive care unit procedures such as central venous catheters.3 There is a paucity of literature describing Rhodotorula infections of the eye.Heavy metal––not just hard on the ears: siderosis following retained intraocular foreign body
Ocular siderosis results from the toxic effects of iron released from retained metallic intraocular foreign bodies (IOFBs).1 Over time, intraocular iron dissociates and deposits in epithelial structures, including the lens, iris, ciliary body, and retina, resulting in degeneration of ocular tissues.2
