1/9. Postoperative intraocular pressure elevation after the use of Healon GV in pediatric cataract surgery.intraocular pressure elevation after the use of viscoelastic agents in uncomplicated cataract surgery has been well documented in adults. However, pediatric patients are thought to clear residual viscoelastic agents from the anterior chamber more easily than adults, presumably because of healthier trabecular meshwork. (1) We report on a series of 4 eyes of 4 children with previously normal intraocular pressure who underwent cataract extraction with primary (3 patients) or secondary (1 patient) intraocular lens implantation with Healon GV, which was complicated by marked postoperative intraocular pressure elevation (greater than 30 mm Hg). The patients, aged 5 to 14 years, had an intraocular pressure ranging from 34 to 50 mm Hg with Tonopen or applanation tonometry 1 day, postoperatively associated with nausea, eye pain, and microcystic corneal edema. Viscoelastic material was not entirely removed during surgery. Each of these cases occurred after a change in our preferred viscoelastic agent from one with less viscosity to Healon GV. Medical management controlled the elevated intraocular pressure in all cases without affecting the visual outcome. However, 1 patient with intractable nausea and vomiting required hospitalization for rehydration. With meticulous removal of all viscoelastic material at the completion of surgery, we have not documented any additional cases of postoperative pressure elevation.- - - - - - - - - - ranking = 1keywords = extraction (Clic here for more details about this article) |
2/9. Preservation of residual field after surgical lowering of intraocular pressure.A 52-year-old Caucasian woman with pigmentary glaucoma underwent a left cyclodiathermy procedure for raised intraocular pressure (IOP) in 1962 and right sclerectomy the following year. Over 25 years later a low IOP was still maintained though pilocarpine was needed in the left eye. After a left cataract extraction with insertion of a posterior chamber lens, field loss had not progressed very much in either eye though the visual acuity was reduced in the more affected eye. Both drainage operation and a cyclodestructive procedure controlled IOP over a long period of time in this patient and were associated with only a very gradual progression of field loss.- - - - - - - - - - ranking = 1keywords = extraction (Clic here for more details about this article) |
3/9. Continuous control of intraocular pressure in pseudophakic retinal detachment surgery.We describe a method for continuous control of intraocular pressure in pseudophakic retinal detachment surgery done shortly after extracapsular cataract extraction and posterior chamber intraocular lens implantation. The system consists of a special needle inserted into the anterior chamber through the corneal limbus. The needle is attached by a regular intravenous administration set to an infusion bag. This allows fluids to exit the eye when the eyeball is compressed and to return to the eye when pressure on the eye is released. The presence of an intact posterior capsule and an intraocular lens do not impose a significant barrier to the passage of fluids between the anterior chamber and the vitreous cavity. Using this technique, intraocular pressure can be stabilized throughout the operation. The implementation of this system is demonstrated by a case report.- - - - - - - - - - ranking = 1keywords = extraction (Clic here for more details about this article) |
4/9. Genetic spontaneous late subluxation of the lens. A study of two families.patients with genetic spontaneous late subluxation of the lens may present signs and symptoms other than lens displacement due to secondary anatomic alteration of the anterior segment. Two families are described, one of them with affected individuals in five successive generations. The vast majority of the patients sought consultation because of progressive myopia or intermittent acute intraocular hypertensive crisis which obscured the basic condition. Upon recognition of the disease, the affected patients underwent an uneventful intracapsular extraction. Histopathologic examination of the removed lenses suggested a dysplastic development of lens zonules.- - - - - - - - - - ranking = 1keywords = extraction (Clic here for more details about this article) |
5/9. Intermediate post cataract extraction ischemic optic neuropathy associated with an intraocular lens implant.An 81 year old patient underwent uncomplicated intracapsular cataract extraction with an anterior chamber lens implant. Three weeks after surgery, he developed ischemic optic neuropathy associated with increased intraocular pressure. There was visual recovery with lowering of the intraocular pressure. This is the first documented case of post cataract extraction ischemic optic neuropathy associated with an intraocular lens.- - - - - - - - - - ranking = 6keywords = extraction (Clic here for more details about this article) |
6/9. Choroidal ischemia after extracapsular cataract extraction by phacoemulsification.Three patients developed apparent choroidal ischemia after phacoemulsification. The outer half of the posterior retina appeared white after operation, with confluent lesions in the posterior pole and splotchy white areas in the midperiphery. The separate lesions appeared similar in pattern to the lobular division of the choriocapillaris, and the retinal vessels were not involved. The white lesions resolved in two to three weeks, leaving alterations in the pigment epithelium. Vision was transiently reduced in each eye but returned to a nearly normal level in two of three affected eyes, although paracentral scotomas persisted. In each case of phacoemulsification, the posterior lens capsule was either damaged or was removed. In all three cases, an investigational type of irrigating solution (BSS Plus) containing balanced salt, glutathione, and other constituents was used. Controlled ocular compression was performed before operation using a pneumatic device in two cases. However, the cause of retinal and choroidal damage now described was probably excessively elevated intraocular pressure during the operation.- - - - - - - - - - ranking = 4keywords = extraction (Clic here for more details about this article) |
7/9. Sudden increase in intraocular pressure as an initial manifestation of myelodysplastic syndrome.PURPOSE/methods: We studied a rare initial manifestation of myelodysplastic syndrome in an 82-year-old woman who had acute secondary glaucoma in the right eye and mature cataracts in both eyes. RESULTS/CONCLUSION: Therapy with glaucoma control medications and cataract extraction in the right eye resulted in expulsive hemorrhage and subsequent enucleation of the right eye. After cataract extraction, examination of the left eye disclosed a central serous retinal detachment and hemorrhage. Histopathologic analysis of the right eye demonstrated myelocytic and lymphocytic infiltration.- - - - - - - - - - ranking = 2keywords = extraction (Clic here for more details about this article) |
8/9. Viscoelastic substance in the anterior chamber elevates intraocular pressure.An 85-year-old man underwent an extracapsular cataract extraction OD with posterior chamber intraocular lens implantation. sodium hyaluronate (0.3 mL) was used during the procedure, and approximately 1.0 mL of the solution, including the sodium hyaluronate, was aspirated before wound closure. The next day, the intraocular pressure OD was elevated to 60 mmHg, and it remained high despite medication. Three days later, the intraocular pressure was still high, a paracentesis was done, and viscous solution was obtained. After the paracentesis, the intraocular pressure OD normalized.- - - - - - - - - - ranking = 1keywords = extraction (Clic here for more details about this article) |
9/9. Bacterial endophthalmitis following cataract surgery in an eye with a preexisting Molteno implant.We describe a patient with a preexisting, functioning Molteno implant in whom acute endophthalmitis developed following cataract extraction. The condition was treated successfully without removing the implant.- - - - - - - - - - ranking = 1keywords = extraction (Clic here for more details about this article) |
