Two patients presented with angle closure many years after cataract extraction. The first patient presented with acute intraocular pressure (IOP) elevation and closed iridocorneal angle that resolved with a laser iridotomy. The second patient presented with an insidious course of high IOP and progressive narrowing of the iridocorneal angle, ultimately requiring a pars plana vitrectomy and glaucoma valve implant, with subsequent normalization of pressure and angle anatomy. Although rare, angle closure in eyes with posterior chamber intraocular lenses is a dangerous complication that can occur many years after cataract extraction. Retained lens fragments, and perhaps repeated intravitreal injections, might place susceptible patients at risk.A 6-0 polypropylene suture was introduced in the eye through an ophthalmic viscosurgical device syringe in a completely closed system. The procedure was used to correct optic capture of the intraocular lens by the pupil after two cases of Yamane's technique.
  To describe and discuss the presentation and management of 4 cases of late (17 to 20 years) postoperative spontaneous posterior capsule rupture (PCR) and intraocular lens (IOL) subluxation in eyes implanted with the same hydrophilic 1-piece IOL.

  Case series.
 
  Four patients presented with spontaneous rupture and posterior dislocation of the same design IOL (B-Lens, Hanita Lenses, Israel) 17 to 20 years after implantation. No trauma or any other direct causative factor was identified in any of the cases.
 
  The lenses were successfully repositioned to the ciliary sulcus and sutured to the scleral wall (1 case) or the iris (2 cases), and the IOL was stable in the sulcus without the need for further sutured fixation in 1 case, with effective vision restored in all cases..
 
  Spontaneous PCR is a rare postoperative complication and has not been reported, to the authors' knowledge, in cases without predisposing factors.  https://www.selleckchem.com/products/sbfi-26.html  A mechanism of late capsular tear was not confirmed but the specific design of the IOL might have been a contributing factor.

  To document a case of a biphenotypic sinonasal sarcoma that impinged on the orbit via a tumor-induced mucocele and review the previous literature devoted to this condition.
 
  A clinicopathologic case report with detailed histopathologic, immunohistochemical, and radiological studies with tabulations of previously reported cases and immunohistochemical stains for ruling out mimicking lesions.
 
  A biphenotypic sinonasal sarcoma arose from the ethmoid sinus in a middle-aged man. The tumor induced a mucocele that bowed the medial orbital lamina papyracea into the orbit and caused diplopia and mild proptosis. The biopsy's dual positivity for S100 and smooth muscle actin together with positive paired box 3 immunohistochemical staining established the diagnosis of biphenotypic sinonasal sarcoma.
 
  Biphenotypic sinonasal sarcoma, which can involve the orbit in 25% of cases, is a rare head and neck malignancy that has only recently been described. Biphenotypic sinonasal sarcoma is a low-grade, locally aggressive, noning can be used as an alternative diagnostic marker. The current case is most unusual because the orbital findings were induced by a mucocele caused by the tumor that obstructed the sinus ostium. This produced diplopia without direct tumor invasion into the orbital fat.A 39-year-old male presented with bilateral hearing loss and progressive left eye vision loss over a 14-month period. The development of systemic symptoms including arthralgias, enlarged lymph nodes, and profound leg weakness, prompted a workup for lymphoproliferative disease, infection, and autoimmune inflammatory conditions which was unrevealing. Subsequently, the right visual acuity declined from 20/25 to 20/70 and the left to hand motions due to corneal interstitial keratitis. There was limitation of left infraduction. Neuroimaging revealed dural thickening of the internal auditory canals, cavernous sinuses, cerebellum, and along the optic nerves. There was fusiform enhancing enlargement of the left inferior and medial rectus muscles and pathologic enlargement of the left lacrimal gland. Biopsy of the left lacrimal gland and left inferior rectus revealed fibrosis and lymphocytic infiltration. The patient was diagnosed with atypical Cogan syndrome and treated with oral prednisone, with improvement in visual acuity of the right eye, motility of the left eye, and systemic weakness.
  Free skin grafts are frequently used in reconstructive surgery. However, little is known about the course of reperfusion due to the previous lack of reliable perfusion monitoring techniques. The aim of this study was to use state-of-the-art laser speckle contrast imaging to monitor free skin grafts in the periocular area.
 
  Seven patients needing surgery due to tumor removal or cicatricial ectropion in the periocular region underwent reconstructive surgery using free skin grafts from either the contralateral upper eyelid or the upper inner arm. The free skin grafts measured 10-30 mm horizontally and 9-30 mm vertically. Blood perfusion was monitored using laser speckle contrast imaging immediately postoperatively (0 weeks) and at follow-up after 1, 3, and 7 weeks.
 
  All grafts were reperfused gradually during healing, the median value being 46% in the central part of the graft after 1 week and 79% after 3 weeks. The grafts were completely reperfused after 7 weeks. No difference was observed in the rate of reperfusion between the center and periphery of the grafts (p = not significant). The cosmetic and functional outcome was excellent in all but 1 patient, who developed ectropion that had to be surgically corrected.
 
  Skin grafts in the periorbital area are fully reperfused after 7 weeks. The periocular area is known to be well-vascularized and thus forgiving to reconstructive surgery. Future investigations of the reperfusion of free skin grafts in other parts of the body or in higher-risk populations should be carried out.
