1/9. Early acute aseptic iritis after cataract extraction.Severe iritis which occurs within the first five days after cataract extraction may be categorized as (1) bacterial endophthalmitis, (2) toxic iritis, or (3) aseptic iritis. These entities can sometimes be distinguished because of their clinical features. If bacterial endophthalmitis is suspected, anterior chamber paracentesis should be considered and appropriate antibiotic treatment should be initiated. Acute iritis may result from the introduction of toxic agents into the eye, and may follow the use of products sterilized with ethylene oxide. Early acute aseptic iritis probably occurs more often than has previously been recognized. Response to intensive anti-inflammatory treatment is usually prompt and dramatic. The judicious use of cryoextraction and the careful manipulation of intraocular tissues may minimize the incidence and the severity of postoperative inflammation.- - - - - - - - - - ranking = 1keywords = extraction (Clic here for more details about this article) |
2/9. Long-term posterior and anterior segment complications of immune recovery uveitis associated with cytomegalovirus retinitis.PURPOSE: To identify and describe long-term posterior and anterior segment complications of immune recovery uveitis in patients with inactive cytomegalovirus retinitis who are undergoing highly active antiretroviral therapy-mediated recovery of immune function.methods: A prospective cohort study at a university medical center. Twenty-nine eyes of 21 patients with immune recovery uveitis and inactive cytomegalovirus retinitis were followed for 14.5 to 116 weeks (median, 43 weeks) after diagnosis of immune recovery uveitis. RESULTS: Nine eyes of nine patients developed visually important complications involving the posterior segment, anterior segment, or a combination of both. Posterior segment complications included severe proliferative vitreoretinopathy in three eyes and spontaneous vitreous hemorrhage from avulsion of a blood vessel secondary to contraction of the inflamed vitreous in one eye. Proliferative vitreoretinopathy recurred in all cases after surgery, severely compromising the visual outcome. Anterior segment complications included posterior subcapsular cataracts with vision decrease in five eyes and persistent anterior chamber inflammation after cataract extraction, resulting in posterior synechiae and large visually important lens deposits in three eyes.CONCLUSION: Persistent inflammation in immune recovery uveitis may lead to vision-threatening complications, such as proliferative vitreoretinopathy, posterior subcapsular cataracts, and severe postoperative inflammation. Immune recovery uveitis is a chronic inflammatory syndrome that may result in complications months to years after the onset of inflammation.- - - - - - - - - - ranking = 0.16666666666667keywords = extraction (Clic here for more details about this article) |
3/9. histoplasma capsulatum endophthalmitis after cataract extraction.A 60-year-old white man from an area endemic for histoplasma capsulatum presented with a vitreous wick, hypopyon iritis, and dense vitreitis 2 months after removal of an anterior chamber intraocular lens (IOL) for chronic iritis. A diagnostic vitrectomy was performed and H. capsulatum was cultured and identified 2 weeks later. Despite intravitreal and intravenous amphotericin as well as repeat vitrectomies, the inflammation worsened and the eye was removed. Results of histopathologic examination showed histoplasma organisms along the vitreous wick, over the surface of the iris and ciliary body, and over the retina. No organisms were found in the choroid. Dalen-Fuchs-type nodules similar to those of sarcoid also were noted, but there was no evidence of granulomatous inflammation in the uvea. Because of his unilateral disease with histoplasma in the vitreous wick, negative serology, and an absence of systemic infection, the authors believe that this patient had a previously unreported form of ocular histoplasma, exogenous postoperative histoplasma endophthalmitis.- - - - - - - - - - ranking = 0.66666666666667keywords = extraction (Clic here for more details about this article) |

5/9. Intraocular inflammation of denatured viscoelastic substance in cases of cataract extraction and lens implantation.I present three successive pseudophakic cases that had intraocular inflammation (iritis) and bullous keratopathy presumably caused by denatured sodium hyaluronate (Healon). The denatured Healon was injected into the anterior chamber mixed with fresh Healon during routine planned extracapsular cataract extraction and intraocular lens implantation, when the cannula was reused after sterilization by disinfectants and autoclaving. A residuum of the viscoelastic substance remained inside the cannula and its nature was changed to a toxic chemical by the action of disinfectants and the sterilization procedures. The first two cases developed pseudophakic bullous keratopathy and had successful penetrating keratoplasties performed. The third case had minimal intraocular inflammation. The hypothesis that this intraocular reaction was due to denatured Healon was confirmed by use of a rabbit eye model. I recommend using a single-use disposable cannula for intracameral administration of Healon.- - - - - - - - - - ranking = 0.83333333333333keywords = extraction (Clic here for more details about this article) |
6/9. pseudomonas cepacia endophthalmitis.A 72-year-old white man who had undergone surgical trabeculectomy and extracapsular cataract extraction with a posterior-chamber lens implantation in the left eye suffered from chronic iridocyclitis for eight months. He subsequently presented with acute hypopyon and vitritis. Anterior-chamber and vitreous cultures were positive for pseudomonas cepacia. The infection was successfully treated with subconjunctival piperacillin, intravitreal cefotaxime, and intravenous piperacillin and gentamicin. To our knowledge, this is the first documented case of pseudomonas cepacia endophthalmitis.- - - - - - - - - - ranking = 0.16666666666667keywords = extraction (Clic here for more details about this article) |
7/9. Endothelial line associated with pseudophakic bullous keratopathy.Three patients undergoing uncomplicated cataract extraction with intraocular lens implantation developed an endothelial line, clinically appearing identical to that seen in allograft rejection following corneal transplantation. Both intracapsular and extracapsular surgery were involved. Three different intraocular lens types were implanted (pupillary supported, anterior chamber, and posterior chamber). Each case was associated with postoperative iritis and glaucoma. They were nonresponsive to steroid therapy and eventually resulted in total corneal decompensation. This clinical entity may represent an autoimmune phenomenon stimulated by chronic inflammation induced by the intraocular lens.- - - - - - - - - - ranking = 0.16666666666667keywords = extraction (Clic here for more details about this article) |
8/9. Management of postoperative and post-traumatic cyclodialysis clefts with argon laser photocoagulation.Cyclodialysis clefts, which occur following cataract extraction or ocular trauma, occasionally lead to chronic hypotony and loss of vision in the involved eye. In the past, this complication of trauma and surgery has been managed by additional surgical procedures designed to close the cyclodialysis cleft. This report will describe the first patient treated with argon laser photocoagulation with successful physiologic closure of the cleft with subsequent restoration of both normal intraocular pressure and normal vision. The method of treatment and speculations about the mechanism of cleft closure are discussed.- - - - - - - - - - ranking = 0.16666666666667keywords = extraction (Clic here for more details about this article) |
9/9. Cataract surgery in a patient with severe chronic iritis and corneal endothelial damage.We report a patient with broad anterior synechias and corneal endothelial damage. The patient had chronic iritis and cataracts secondary to chronic iritis in both eyes. Because the right eye had broad anterior synechias and severe corneal endothelial damage, extracapsular cataract extraction and intraocular lens implantation were performed through the basal iris. Good postoperative visual acuity was obtained. The cornea showed little trauma from the surgery and remained clear 36 months postoperatively.- - - - - - - - - - ranking = 0.16666666666667keywords = extraction (Clic here for more details about this article) |
