1/11. Ultrasound biomicroscopy of chronic hypotony after cataract extraction.Ultrasound biomicroscopy was performed with a UBM 840 (Zeiss-Humphrey) equipped with a 50 MHz probe on a patient with chronic hypotony 1 year after cataract surgery by phacoemulsification with intraocular lens implantation in the capsular bag. This sonographic technique, which provides high-resolution imaging of the anterior segment, showed aqueous humor leakage through the former scleral tunnel incision. Ultrasound biomicroscopy helped detect this patient's postoperative complication and is a good tool for diagnostic procedures in patients with chronic hypotony.- - - - - - - - - - ranking = 1keywords = extraction (Clic here for more details about this article) |
2/11. Peritubular filtration as cause of severe hypotony after Ahmed valve implantation for glaucoma.PURPOSE: To report peritubular filtration as the cause of severe hypotony after Ahmed valve implantation. methods: Interventional case report. In a 65-year-old man with primary open-angle glaucoma, ultrasound biomicroscopy was used to image the peritubular region of his right eye that had severe hypotony during the early postoperative period after an Ahmed valve implantation. RESULTS: The ultrasound biomicroscopy examination showed peritubular filtration. Additional surgery consisting of tube extraction, closure of the previous insertion opening, reformation of the anterior chamber with viscoelastic, and reintroduction of the tube through a new paracentesis was performed to solve this complication. Twenty-four hours postoperatively, the intraocular pressure increased to 10 mm Hg. During the 6-month follow-up, the mean intraocular pressure was 16.36 mm Hg (standard deviation, 1.45). CONCLUSION: The possibility of peritubular filtration should be considered in eyes with severe hypotony after restrictive valve implantation.- - - - - - - - - - ranking = 0.25keywords = extraction (Clic here for more details about this article) |
3/11. Hypotony maculopathy: improvement of visual acuity after 7 years.PURPOSE: To describe a 79-year-old Caucasian male with a history of hypotony maculopathy for 7 years after cataract extraction with subsequent recovery of normal intraocular pressure and improvement of visual acuity. methods: Interventional case report. The patient developed an intraocular pressure ranging from 0 to 5 mm Hg after cataract surgery. He developed hypotony maculopathy, and the visual acuity declined to 20/200. On evaluation 7 years later, a superior cyclodialysis cleft was detected and treated with the argon laser. RESULTS: Closure of the cleft with argon laser was successful. The intraocular pressure stabilized at 17 to 20 mm Hg, and the visual acuity improved to 20/30. CONCLUSION: The development of hypotony maculopathy leads to impairment of visual acuity. This case demonstrates that visual acuity can improve after resolution of the maculopathy even after several years of hypotony.- - - - - - - - - - ranking = 0.25keywords = extraction (Clic here for more details about this article) |
4/11. Management of a displaced angle-supported anterior chamber intraocular lens.A 49-year-old patient had a displacement of an anterior chamber intraocular lens (IOL) producing a cyclodialysis cleft and persistent hypotony with maculopathy. The patient underwent intraocular lens extraction, repair of the cyclodialysis cleft, and iris-fixation of an acrylic posterior chamber IOL with resolution of the hypotony and improvement of the maculopathy and best-corrected visual acuity. Many surgeons consider the implantation of an anterior chamber IOL as their first choice in the treatment of inadequate capsule support associated with cataract surgery, probably because it is a relatively easy procedure to perform. However, insufficient preoperative knowledge of the anterior segment biometry can lead to inadequate lens size and postoperative complications.- - - - - - - - - - ranking = 0.25keywords = extraction (Clic here for more details about this article) |
5/11. Management of the hypotonous cyclodialysis cleft.Authoritative experience in the management of hypotonous cyclodialysis clefts is difficult to obtain because of their rarity. In this study, the authors describe nine patients with hypotonous cyclodialyses clefts: six patients were treated successfully with argon laser photocoagulation to the cleft surfaces; in one patient, cleft diathermy was used to seal an incompletely closed cleft after a single argon laser treatment; one patient responded to conservative management; another patient did not require treatment. Four cases followed ocular trauma and five occurred after extracapsular cataract extraction and posterior chamber intraocular lens implantation. In three patients, the anterior chamber was too shallow to permit gonioscopy; sodium hyaluronate (Healon) was used to reform the anterior chamber, to delineate the extent of the cyclodialysis cleft, and to provide maximal access for the argon laser treatment. In another patient, laser cleft consolidation was successful only after fully opening the cleft with sodium hyaluronate. The evolution of the laser photocoagulation technique used by the authors is described. Laser cyclodialysis cleft consolidation can be repeated easily and safely. The authors recommend argon laser photocoagulation as the primary management approach. Intracameral viscoelastic agents are useful adjuncts. The complications of cleft lasering are minor, although a hypertensive episode commonly occurs in the early postoperative period as the cleft closes. Major intraocular surgeries usually can be avoided.- - - - - - - - - - ranking = 0.25keywords = extraction (Clic here for more details about this article) |
6/11. iris retraction syndrome after intraocular surgery.BACKGROUND: The authors report the postoperative development of iris retraction syndrome in two individuals. This is a rare syndrome that can present with pupillary block after an unrepaired rhegmatogenous retinal detachment. patients: The authors report two patients who had the iris retraction syndrome shortly after intraocular surgery. One patient had pupillary block that developed 6 months after cataract extraction and posterior chamber intraocular lens implantation. A second patient had uveitis, hypotony, and pupillary seclusion 4 weeks after pars plana vitrectomy. RESULTS: Both patients were treated successfully with a scleral buckling procedure and peripheral iridectomy. CONCLUSION: Postoperative uveitis that occurs with iris retraction and pupillary seclusion should alert the physician of an occult retinal detachment and warrant a thorough dilated funduscopic examination. Features unique to this report include the development of iris retraction syndrome in the presence of a pseudophakos, the rapidity of onset of this disorder after retinal detachment, and its masquerade as a persistent postoperative uveitis.- - - - - - - - - - ranking = 0.25keywords = extraction (Clic here for more details about this article) |
7/11. Inadvertent cyclodialysis cleft.We report four patients with functionally significant inadvertent cyclodialysis cleft. In three, the cleft followed uneventful extracapsular cataract extraction with posterior chamber intraocular lens implantation; in the fourth, blunt trauma with hyphema. Ocular hypotony resolved in three patients with medical therapy; the fourth required argon laser photocoagulation. Causes, clinical findings, and treatment of inadvertent cyclodialysis cleft are reviewed.- - - - - - - - - - ranking = 0.25keywords = extraction (Clic here for more details about this article) |
8/11. cataract extraction and intraocular lens implantation in eyes with phacomorphic or phacolytic glaucoma.We describe nine patients who had phacomorphic or phacolytic glaucoma. After intraocular pressure (IOP) was reduced medically, all patients had extracapsular cataract extraction. All had intraocular lens implantation except one. The surgery improved visual acuity and resulted in normal IOP in all eyes.- - - - - - - - - - ranking = 1.25keywords = extraction (Clic here for more details about this article) |
9/11. Recurrent choroidal detachment following combined trabeculectomy and cataract extraction.Two patients with glaucoma who underwent uneventful trabeculectomy and extracapsular cataract extraction with posterior chamber intraocular lens implantation, experienced late and recurrent choroidal detachment. Both patients received aqueous suppressant therapy before and after surgery. Hypotony and choroidal detachment occurred 7 months and 15 months after the combined surgery. There was no shallowing of the anterior chamber or leakage from the filtering blebs, and there were no signs of inflammation. The choroidal detachment completely resolved in the two patients 4 days and 4 weeks following discontinuation of the aqueous suppressant therapy.- - - - - - - - - - ranking = 1.25keywords = extraction (Clic here for more details about this article) |
10/11. cataract extraction as a means of treating postfiltration hypotony maculopathy.Hypotony maculopathy may arise after glaucoma filtering surgery. This can be treated by inducing inflammation and scarring within the filter, with the aim of increasing intraocular pressure (IOP) and promoting resolution of maculopathy. cataract extraction can promote such inflammation. phacoemulsification with posterior chamber intraocular lens (PC IOL) implantation was performed in two consecutive patients with postfiltration hypotony maculopathy and preexisting cataracts. After cataract extraction, improvement of IOP, visual acuity, maculopathy, and metamorphopsia occurred in both patients. cataract extraction can be beneficial in the management of postfiltration hypotony maculopathy.- - - - - - - - - - ranking = 1.75keywords = extraction (Clic here for more details about this article) |
