1/57. Management of traumatic cyclodialysis cleft associated with ocular hypotony.BACKGROUND AND OBJECTIVE: To evaluate the efficacy of direct cyclopexy for treatment of traumatic cyclodialysis cleft associated with ocular hypotony. patients AND methods: Eyes with traumatic cyclodialysis cleft were treated with direct cyclopexy or 1.0% atropine eyedrop. RESULTS: Five eyes with a large cyclodialysis cleft were treated with direct cyclopexy. Postoperatively, these eyes obtained normal intraocular pressure. Four of the 5 eyes had good visual acuity, and 1 eye that had preoperative subretinal hemorrhage in the macula had poor visual acuity. Of the 3 eyes treated with 1.0% atropine eyedrops, 1 had good visual acuity, and 2 with retinal folds had fairly good and poor visual acuity. CONCLUSION: The present study showed that direct cyclopexy is useful for the treatment of traumatic cyclodialysis cleft associated with ocular hypotony, and that the cyclodialysis should be surgically treated before irreversible retinal folds develop.- - - - - - - - - - ranking = 1keywords = pressure (Clic here for more details about this article) |
2/57. Elastic cord-induced cyclodialysis cleft and hypotony maculopathy.We describe a case of hypotony maculopathy in which hypotony was due to a cyclodialysis cleft produced by an elastic cord injury. Sixteen months after being hit with an elastic cord, a 43-year-old white male presented with progressive loss of vision in the right eye. The visual acuity in the right eye was 1/200 due, in part, to a subluxated and cataractous lens. The intraocular pressure (IOP) was 4 mm Hg. gonioscopy revealed a cyclodialysis cleft at the 2 o'clock position, and fundus examination showed hypotony maculopathy. The patient underwent pars plana vitrectomy, pars plana lensectomy, repair of the cyclodialysis cleft, placement of an anterior chamber intraocular lens, and tightly sutured trabeculectomy without antimetabolite. Sixteen months following surgery, visual acuity was stable at 20/60 and IOP was 11 mm Hg but the chorioretinal folds persisted.- - - - - - - - - - ranking = 1keywords = pressure (Clic here for more details about this article) |
3/57. ciliary body detachment caused by capsule contraction.A 74-year-old woman developed capsule contraction associated with hypotony and choroidal effusion 18 months after uneventful phacoemulsification with 3-piece poly(methyl methacrylate) intraocular lens implantation. Ultrasound biomicroscopy revealed ciliary body detachment and stretched zonules. A radial neodymium: YAG anterior capsulotomy was performed, resulting in the resolution of the ciliary body detachment and choroidal effusion as well as in normal intraocular pressure over 4 days.- - - - - - - - - - ranking = 1keywords = pressure (Clic here for more details about this article) |
4/57. Combination of autologous blood injection and bleb compression sutures to treat hypotony maculopathy.PURPOSE: To report successful use of a combination of autologous blood injection and bleb compression sutures to treat overfiltration with hypotony maculopathy after trabeculectomy with mitomycin C. methods: Two patients underwent the combined procedure and were followed until visual acuity and intraocular pressure (IOP) were stable over three consecutive visits (4 to 9 months). RESULTS: Both patients experienced improvement in visual acuity both subjectively and objectively, and both patients had an elevation in IOP that persisted over three consecutive visits. CONCLUSIONS: Combination autologous blood injection and bleb compression suture placement may be an effective means of treating hypotony maculopathy after trabeculectomy with mitomycin C.- - - - - - - - - - ranking = 1keywords = pressure (Clic here for more details about this article) |
5/57. Treatment of a cyclodialysis cleft by means of ophthalmic laser microendoscope endophotocoagulation.PURPOSE: To report on the repair of a cyclodialysis cleft by means of endolaser photocoagulation. METHOD: Case report. We describe treatment of a cyclodialysis cleft by means of endolaser photocoagulation with a diode laser. RESULTS: In a 8-year-old boy with pseudophakia and secondary glaucoma in the right eye, combined trabeculectomy/trabeculotomy was performed. Ten months later, the patient was seen with persistent hypotony with a flat filtration bleb. The hypotony was unresponsive to all forms of medical therapy. Reformation of the anterior chamber along with synechialysis revealed a 2.5 clock-hour cyclodialysis cleft by means of gonioscopy. A laser microendoscope probe was used and laser was applied to both the internal scleral and external ciliary body surfaces within the depths of the cleft. Within 3 weeks after treatment, intraocular pressure increased to 15 mm Hg and has remained at that level as of 9 months after the endolaser photocoagulation procedure. CONCLUSION: Endolaser photocoagulation with the ophthalmic laser microendoscope may be an appropriate procedure, after failure of medical therapy, for the diagnosis and repair of a cyclodialysis cleft, especially in the pediatric population.- - - - - - - - - - ranking = 1keywords = pressure (Clic here for more details about this article) |
6/57. indocyanine green angiographic findings in 3 patients with traumatic hypotony maculopathy.PURPOSE: Little is known about the choroidal circulation in human eyes with ocular hypotony. Recently, indocyanine green angiography (IA) became a useful method for examining choroidal circulation. The present study using IA was designed to determine choroidal circulatory disturbances in patients with traumatic hypotony maculopathy. methods: indocyanine green angiography was performed on 3 consecutive patients (3 eyes) with traumatic hypotony. One patient underwent IA using an infrared fundus camera only during the hypotony stage. The other 2 patients underwent IA using a scanning laser ophthalmoscope before and after recovery of intraocular pressure (IOP). RESULTS: During the hypotony stage, IA revealed multiple hypofluorescent spots in many parts of the fundus, sector hypofluorescent areas, dilatation, and tortuosity of the choroidal vessels in the posterior pole. These findings had not been detected by fluorescein angiography. After surgical treatment, IOP returned to the normal range and visual acuity improved. indocyanine green angiography showed improvement of the sector hypofluorescent areas, and dilatation and tortuosity of choroidal vessels in the posterior pole. However, most of the hypofluorescent spots and regional delay of choroidal filling remained. CONCLUSIONS: indocyanine green angiography revealed that choroidal circulatory disturbances occurred during the hypotony stage and that some remained during the recovery stage.- - - - - - - - - - ranking = 1keywords = pressure (Clic here for more details about this article) |
7/57. Management of hypotony maculopathy and a large filtering bleb after trabeculectomy with mitomycin C: success with argon laser therapy.We report a patient with postkeratoplasty glaucoma that developed a large, filtering bleb following trabeculectomy with intraoperative antimetabolite treatment. The hypotony and the bleb were managed using argon laser photocoagulation. A 26-year-old female patient underwent penetrating keratoplasty in the left eye for keratoconus. Postoperatively, her elevated intraocular pressure could not be controlled medically, and the patient underwent a trabeculectomy with intraoperative antimetabolite application. Two months later, hypotony maculopathy, optic disc edema, and choroidal folds developed, and her vision dropped. Steroid treatment and soft contact lenses did not help. Photocoagulation was applied twice to the surface of the bleb and the surrounding area. After the photocoagulation therapy, the patient's vision improved, intraocular pressure increased, and the optic disc edema and macular folds had resolved. argon laser photocoagulation applied to a large filtering bleb associated with hypotony maculopathy is a useful treatment for bleb remodeling and elevating intraocular pressure.- - - - - - - - - - ranking = 3keywords = pressure (Clic here for more details about this article) |
8/57. Paradoxical hypotony after laser in situ keratomileusis.We present a case of paradoxically low (0 to 2 mm Hg) intraocular pressure (IOP) measured by Goldmann applanation and Tono-Pen tonometry in an eye with corticosteroid-induced high IOP after laser in situ keratomileusis. The patient complained of blurred vision and ocular pain in both eyes. The eyes were firm by palpation, and the IOP measured by Schiotz indentation tonometry was 38 mm Hg. An interface fluid pocket was identified by slitlamp examination, and the corneal surface became steeper. These findings resolved after flap relifting, interface irrigation, and addition of antiglaucoma medications. We postulate that the paradoxically low reading by applanation tonometry was due to fluid accumulation within the flap-bed interface. The applanation tonometry reflected the interface fluid pocket pressure rather than the real high IOP. An exceedingly low IOP should be verified by palpation or by Shiotz indentation tonometry, and interface fluid should be identified.- - - - - - - - - - ranking = 2keywords = pressure (Clic here for more details about this article) |
9/57. Ibopamine treatment in chronic hypotony secondary to long-lasting uveitis. A case report.PURPOSE: To assess the clinical efficacy of ibopamine eye drops in severe hypotony secondary to chronic progressive uveitis. methods: Case report. A 47-year-old man with a 37-year history of diffuse uveitis and severe refractory hypotony was treated with topical 2% ibopamine (Trazyl) six times a day. intraocular pressure, visual acuity, visual field and side effects were recorded during 15 months of follow-up. RESULTS: IOP, visual acuity and visual field increased after four days of therapy and lasted for two months when the drug was suspended because of the onset of filamentous keratopathy. A new course of treatment with 2% ibopamine eye drops in a different solvent (BSS) resulted in a stable increase in IOP, VA and visual field, with no side effects in a follow-up of 13 months. CONCLUSIONS: Ibopamine 2% eye drops in BSS solvent seem effective in the treatment of uveitis-related hypotony.- - - - - - - - - - ranking = 1keywords = pressure (Clic here for more details about this article) |
10/57. Occult wound leak diagnosed by ultrasound biomicroscopy in patients with postoperative hypotony.PURPOSE: To describe the ability of high-frequency ultrasound biomicroscopy (UBM) to diagnose occult wound leaks as a cause for hypotony after cataract surgery. methods: Six patients with persistent hypotony after cataract surgery were sent for UBM examination. Slitlamp examination and gonioscopy of the 6 eyes had not revealed a cause for the hypotony. RESULTS: Ultrasound biomicroscopy showed subtle wound separation with shallow conjunctival elevation at the site of the cataract wound in the 6 patients. Two eyes had surgical repair of the subconjunctival wound leak, and the other 4 were treated medically. In the 2 eyes with surgically repaired wounds, the hypotony cleared after wound closure. Of the 4 medically treated eyes, hypotony resolved in 2 and 1 had a recurrence of hypotony. The other 2 eyes had fluctuating intraocular pressure for an extended period. CONCLUSIONS: Hypotony after cataract surgery occurred in 6 eyes due to subtle wound leaks difficult to detect by clinical observation. Ultrasound biomicroscopy can be a helpful aid to clinical examination in detecting these leaks.- - - - - - - - - - ranking = 1keywords = pressure (Clic here for more details about this article) |
