Abstract: we describe different methods to prepare postmortem human or animal eyes used at the center for research in ocular therapeutics and biodevices at the storm eye institute, medical university of south carolina, charleston, sc, usa. these techniques have been utilized for performing different surgical procedures (phacoemulsification, extracapsular cataract extraction, etc.), and for training of surgeons in-transition. performing these techniques in the wet-laboratory contributed to improve surgical skills to perform the critical steps of the phacoemulsification surgery. pathological evaluation of pseudophakic postmortem human eyes using the miyake-apple posterior view and histology was helpful to analyze postoperative complications of cataract surgery (anterior capsule opacification and posterior capsule opacification) secondary to postoperative proliferation of lens epithelial cells into the capsular bag. modifications in the surgical techniques and/or lens design may be helpful to reduce these postoperative complications. implantation of various aphakic and phakic intraocular lenses in postmortem human eyes as well as animal eyes was helpful to analyze the sizing and fitting of new lens designs within the eye.

Abstract: Objetivo/Métodos: Presentamos el caso de una mujer de 60 a os que tras ser intervenida por desprendimiento de retina, en su ojo izquierdo, presenta cuadro clínico que inicialmente se confunde con endoftalmitis. Resultados/Conclusiones: La paciente presentó un síndrome de isquemia anterior posterior a la intervención quirúrgica, descubriéndose, de forma casual, la presencia de una calcificación intraocular. Valoramos si en el proceso isquémico influyó la neoformación osteoblástica. Objective/Methods: We report the case of a sixty-year-old female that following retinal detachment surgery in her left eye, presented with a clinical picture that initially was misdiagnosed as endophthalmitis. Results/Conclusions: The patient suffered an anterior ischemic syndrome secondary to the retinal surgery, and accidentally, the presence of an intraocular calcification was discovered. We study the influence of the osteoblastic neoformation in the ischemic process.

Indian Journal of Ophthalmology , 1993,
Abstract: We used anterior capsular support for posterior chamber intraocular lenses (PC IOLs) in fourteen eyes with large posterior capsular ruptures. An endocapsular technique preserved the anterior capsule and facilitated implantation. With a median follow up of 8.5 months, all patients had a visual acuity of 6/9 or better. One lens was lost in the vitreous and one patient had a clinically significant cystoid macular edema. In the event of a posterior capsular rupture we suggest this technique as an alternative to anterior chamber or scleral-fixated lenses
Toxic Anterior Segment Syndrome after Foldable Artiflex Iris-Fixated Phakic Intraocular Lens Implantation  [PDF]

Abstract: Toxic anterior segment syndrome (TASS) developed in four cases after uneventful implantation of a foldable iris-fixated phakic intraocular lens (pIOL). Two cases occurred sequentially in one patient. The TASS subsided without complications in all cases after intensive topical steroid treatment. A multitude of possible causes is considered for the occurrence of these TASS cases. From the sterilization and cleaning of surgical instruments to the possibility of endotoxines in ophthalmic viscosurgical devices (OVD). These rare cases should alert the surgeon to the possibility of TASS after pIOL implantation. 1. Introduction Toxic anterior segment syndrome (TASS) is an acute, sterile anterior segment inflammation following any anterior segment surgical procedure [1]. Usually the anterior segment inflammation starts within 12–48 hours after surgery. Clinically alarming symptoms include diminished visual acuity, increased intraocular pressure, corneal edema, inflammation of the anterior chamber, fibrin, hypopyon, and a fixed pupil [2–4]. TASS results from a noninfectious toxic agent within the anterior chamber [5, 6]. The offending substances include denatured ophthalmic viscosurgical devices (OVDs), preservatives, talc from surgical gloves, topical ophthalmic ointment, inappropriately reconstituted intraocular preparations, altered pH and osmolarity of intraocular fluids, heat stable endotoxins, and detergents [5, 6]. Mild to moderate cases respond well to corticosteroids [3, 4], while severe cases might lead to corneal decompensation, glaucoma, a permanently dilated pupil, and cystoid macular edema [2, 3, 7, 8]. TASS is most commonly reported after cataract surgery and rarely after phakic intraocular lens (pIOL) implantation [1, 9, 10]. In the literature, three TASS cases have been reported after pIOL implantation [11, 12]. This report presents three cases of TASS, two of which occurred sequentially in one patient after foldable Artiflex iris-fixated pIOL implantation. 2. Case Reports Case 1. A 45-year-old woman with high myopia consulted our clinic for a refractive surgical procedure. The patient was not contact lens intolerant. History revealed no allergy, uveitis, rheumatic disease, or herpetic keratitis. Corrected distance visual acuity (CDV) in the right and left eye was, respectively, 1.0 and 0.80 with a manifest refraction of, respectively, ?12.25 and ?15.0–0.50?×?135. Photopic (85 candelas/m2) low contrast (2.5%) visual acuity (LCVA) preoperatively was 0.40 and 0.32 in the right and left eye, respectively. Mesopic (0.7 candelas/m2) LCVA

Abstract: AIM: To investigate the effect of anterior chamber puncture combined trabeculectomy in the treatment of high intraocular pressure continued state of acute angle-closure glaucoma. METHODS: Totally 80 cases with angle-closure glaucoma from March 2011 to June 2012 in our hospital were retrospectively analyzed, and 40 cases were given trabeculectomy after anterior chamber decompression(observation group)while 40 cases were received trabeculectomy after drugs decompression(control group). The clinical efficacy was compared between the two groups. RESULTS: The postoperative vision recovery, anterior chamber angle and pupil improvement were better than the control group, and the incidence of complications were less than the control group, the difference was statistically significant(P<0.05). CONCLUSION: The efficacy of anterior chamber paracentesis combined with trabeculectomy in the treatment of high intraocular pressure continued state of acute angle-closure glaucoma is effective, and it is a simple surgery with fewer complications, which is worth to actively promote in clinic.

Abstract: Un evento extremadamente inusual en patología forense es la "expulsión postmortem de un feto" también denominado parto postmortem. El "parto postmortem" se define como la expulsión de un feto muerto tras el fallecimiento de una mujer embarazada cuando el útero materno muestra claros signos de putrefacción. Se considera que los gases generados en la fase enfisematosa de la putrefacción cadavérica dentro de la cavidad abdominal pueden prolapsar el útero y causar la expulsión total o parcial del feto. Presentamos el caso de una mujer embarazada de siete meses que desapareció y fue hallada muerta varios días más tarde en avanzado estado de putrefacción. Antes de practicar la autopsia se procedió a retirar la ropa interior y se encontró el feto fuera de la cavidad pélvica. Al mismo tiempo se realiza una revisión histórica del tema. An extremely unusual event in forensic pathology is the postmortem fetal extrusion or "coffin birth". It is defined as the expulsion of a dead fetus after the death of a pregnant woman when the maternal uterus shows signs of putrefaction. It is considered that the gases generated during the emphysematous phase of the cadaveric putrefaction may distend the uterus causing partial or total fetal extrusion. We present the case of a seven month pregnant woman who disappeared and was found dead some days later in a state of advanced putrefaction. The fetus was discovered inside the woman’s underwear at the moment of undressing the body before autopsy. At the same time, an historical review of the issue is carried out.

Abstract: A 31-year-old man with high axial myopia and strabismus fixus convergens underwent bilateral refractive lens exchange followed by a squint surgery (bilateral superior partial Jensen′s procedure and medial rectus recession). After one year he presented with traumatic anterior dislocation of the sulcus fixated posterior chamber polymethyl methacrylate lens. The lens was dialed back into the ciliary sulcus without any complications. This case highlights the importance of implanting an intraocular lens (IOL) in-the-bag. If the IOL needs to be implanted in the sulcus, a larger diameter of the IOL with larger optic size and overall length is desirable, especially in highly myopic eyes.
