1/15. Sinus polyp-associated soft tissue lesion and unilateral blindness: complications of extraction in leukemic patient.A case of an inflammatory polyp-associated lesion extending through an extraction socket appearing as an intraoral nodular lesion and unilateral blindness secondary to leukemic optic nerve head infiltration is reported. The patient was a 28-year-old male whose his upper first molar had been extracted fifteen days previously. The lesion was an asymptomatic soft tissue mass, red in color and hot tender to palpation, involving the alveolar ridge in the maxillary molar area. Although this is apparently a rare occurrence, the nature of the lesion was suggested by the history, clinical appearance, and radiographic findings. Excision of the inflammatory lesion was followed by complete healing with closure of the lesion. Unfortunately, the blindness was irreversible. The patient is still under leukemia therapy. review of the literature did not yield any other such cases. The role of oral lesions as a diagnostic indicator and the importance of dental surgeons in the diagnosis of leukemic patients are discussed. It is concluded that proper precautions and meticulous early diagnosis are required in these patients and that dental practitioners should be aware of the diagnostic features and possibilities of oral complications associated with leukemia.- - - - - - - - - - ranking = 1keywords = extraction (Clic here for more details about this article) |

Black intraocular lens for leukocoria.We describe a 33-year-old man with leukocoria and no visual potential who obtained an excellent cosmetic result after cataract extraction and implantation of an intraocular lens with an entirely black optic.- - - - - - - - - - ranking = 0.2keywords = extraction (Clic here for more details about this article) |
3/15. Permanent vision loss in one eye following administration of local anesthesia for a dental extraction.prilocaine Plain, an amide local anesthetic (LA), is somewhat less potent than lidocaine and considerably less toxic after injection into peripheral tissues. Clinically, it produces less vasodilation and is similar to other amide LA in relative freedom from allergic reactions. It is reliably used in a plain solution for cardiac patients receiving short procedures. In this report a patient with a known diagnosis of bacterial endocarditis suffered permanent visual loss in the left eye immediately following dental extraction surgery prior to mitral valve surgery. The clinical implications indicate that the delivery of LA must be done with aspiration before and during the injection. This will possibly prevent intravascular injection, which can lead to fluid emboli occluding the ophthalmic artery with the devastating result of vision loss.- - - - - - - - - - ranking = 1keywords = extraction (Clic here for more details about this article) |
4/15. Sudden bilateral visual loss in a diabetic man.This is a report of a case of the development of acute bilateral cataracts in a diabetic patient. A 28-year-old man presented to the emergency room with a 4-day history of acutely diminished vision. The patient had a recent history of hyperglycemia. On examination, vision was noted to be count-fingers bilaterally; both lenses were intumescent with dense cortical opacities. After 4 weeks, the cataracts had not resolved and cataract extraction surgery was performed, with improvement of the patient's vision. A review of the mechanism of this infrequent presentation of cataract is presented.- - - - - - - - - - ranking = 0.2keywords = extraction (Clic here for more details about this article) |
5/15. macular edema and visual loss after macular pucker surgery with ICG-assisted internal limiting membrane peeling.PURPOSE: To describe the occurrence of massive macular edema and visual loss after indocyanine green-assisted (ICG) macular pucker surgery. methods/RESULTS: A 74 years old female presented with a macular pucker and a hypertrophy of the retinal pigment epithelium (RPE) in her left eye. The preoperative visual acuity (VA) was 20/100. Surgery consisted of cataract extraction, lens implantation and standard pars plana vitrectomy with peeling of epiretinal tissue followed by the removal of the internal limiting membrane (ILM) remnants stained using a 0.05% ICG solution. One day after surgery, VA was counting fingers. There was an extensive macular edema and retinal thickening with hyperfluorescence during fluorescein angiography and pronounced autofluorescence using ICG filters. During follow up, the macular edema resolved completely, but VA decreased to 20/800 at six months postoperatively. There was a central scotoma and unstable fixation seen during microperimetry. DISCUSSION: This case report indicates that ICG might come into contact with bare retina if injected following removal of epiretinal membranes. Whether the observed RPE hypertrophy might have contributed to the pathogenesis of the adverse effect described remains hypothetical.- - - - - - - - - - ranking = 0.2keywords = extraction (Clic here for more details about this article) |
6/15. Severe loss of vision after removal of cataract caused by intravitreal triamcinolone in combination with photodynamic therapy for exudative age-related macular degeneration.Intravitreal triamcinolone has been suggested as an adjunctive to photodynamic therapy in the treatment of exudative macular degeneration. One of the side-effects of intravitreal triamcinolone is the development of cataract, and it is known that cataract extraction can exacerbate macular degeneration. A case is presented where combined intravitreal triamcinolone and photodynamic therapy stopped the progression of the exudative macular degeneration. Subsequent progression of cataract required cataract extraction, which resulted in a very rapid progression of the exudative macular degeneration and loss of vision.- - - - - - - - - - ranking = 0.4keywords = extraction (Clic here for more details about this article) |
7/15. Orbital abscess: visual loss following extraction of a tooth--case report.OBJECTIVE: It is the purpose of this article to alert the general practitioner to the severe consequences that may result from a tooth extraction, including the loss of vision, despite the use of antibiotics. CONCLUSIONS: Early and aggressive treatment is critical in obstructing the spread of infection toward the orbits, the eyes, and eventually the brain.- - - - - - - - - - ranking = 1keywords = extraction (Clic here for more details about this article) |
8/15. Bilateral blinding uveitis in a child after secondary intraocular lens implantation for unilateral congenital cataract.A 3-year-old boy underwent secondary implantation of an iris supported intraocular lens following extraction of a unilateral congenital cataract. Eight months later, he developed a bilateral plastic uveitis which, in spite of intensive medical treatment, resulted in NPL (no perception of light) in the implanted eye and 2/60 vision in the fellow eye. Sympathetic ophthalmia possibly played a role in the pathogenesis of the uveitis.- - - - - - - - - - ranking = 0.2keywords = extraction (Clic here for more details about this article) |
9/15. Orbital emphysema causing vision loss after a dental extraction.The use of high-speed air-cooled rotary cutting instruments is common in dental practices. When used near open wounds, the forced air can lead to subcutaneous emphysema and involvement of vital structures. This case highlights the unfortunate episode of orbital emphysema with optic nerve damage after a pneumatically cooled drill was used in the removal of a mandibular second molar.- - - - - - - - - - ranking = 0.8keywords = extraction (Clic here for more details about this article) |
10/15. Immediate contralateral amaurosis after retrobulbar anesthesia.Many potential complications associated with retrobulbar anesthesia have been reported. Of these, sudden loss of vision in the contralateral eye is the least expected. We report a case of immediate loss of vision in the fellow eye after retrobulbar anesthesia for cataract extraction. Possible etiology such as emboli thrown during ventricular fibrillation, direct optic nerve anesthetic injection with reflux to the chiasm, cortical stroke, amaurosis fugax, arterial injection of anesthetic material, and hysteric reaction are discussed.- - - - - - - - - - ranking = 0.2keywords = extraction (Clic here for more details about this article) |
