Extracapsular cataract extraction using a temporal limbal approach after filtering operations.

We reviewed the charts of 29 patients who underwent extracapsular cataract extraction after filtering surgery. Seven of these patients also had simultaneous implantation of a posterior chamber intraocular lens. All eyes were operated on using a temporal limbal approach.

Neodymium-YAG laser posterior capsulotomy for the treatment of aphakic and pseudophakic pupillary block.

We examined five patients who developed pupillary block after extracapsular cataract extraction. One of the patients also had a posterior chamber intraocular lens implanted at the time of cataract operation. In all five patients, pupillary block was promptly relieved by Nd:YAG laser posterior capsulotomy.

Limbal- vs fornix-based conjunctival trabeculectomy flaps.

We studied 20 patients with uncontrolled symmetric glaucoma who had undergone bilateral trabeculectomy after having received the same medical or laser treatment to both eyes. In each patient, the techniques and suture material used in the two eyes were identical, and the surgeon was the same. The only variable was the type of conjunctival flap used: one eye received a limbal-based flap and the other a fornix-based flap.

Aqueous misdirection and flat chamber after posterior chamber implants with and without trabeculectomy.

Three patients developed flat anterior chamber and were ultimately diagnosed as having aqueous misdirection after trabeculectomy with extracapsular cataract extraction and posterior chamber lens implantation (glaucoma triple procedure). A fourth patient developed aqueous misdirection after posterior chamber lens implantation only (without trabeculectomy). This latter was cured by repeated pars plana vitrectomy, not requiring removal of the pseudophakos.

Neodymium-YAG laser iridotomy in the treatment and prevention of angle closure glaucoma. A review of 373 eyes.

The records of 271 consecutive patients (373 eyes) who underwent neodymium-YAG laser iridotomy at our institution over a period of 12 months were reviewed. The majority of eyes (60.5%) were treated for chronic primary angle closure glaucoma, 23.

Eye parameters influencing the results of argon laser trabeculoplasty in primary open-angle glaucoma.

Argon laser trabeculoplasty (ALT) was performed on 173 eyes of 126 patients affected by uncontrolled primary open-angle glaucoma. All subjects were phakic. An overall decrease of intraocular pressure (IOP) from baseline of 19.

Factors affecting the results of argon laser trabeculoplasty in open-angle glaucoma.

Argon laser trabeculoplasty (ALT) was performed in 232 eyes of 180 patients affected by uncontrolled primary open-angle glaucoma (POAG), exfoliation syndrome glaucoma (ESG) or pigment dispersion syndrome glaucoma (PDSG). Mean follow-up was 9 months (3-22). Mean IOP change was -21.

Short- and long-term effects of postoperative corticosteroids on trabeculectomy.

All patients with primary open-angle or primary angle-closure glaucoma requiring trabeculectomy between January 1982 and January 1983 were entered into a randomized prospective study to evaluate the effect of postoperative corticosteroids. Twenty-three eyes in Group 1 received a cycloplegic and topical antibiotic. Twenty-nine eyes in Group 2 received the same treatment, with the addition of topical 1% prednisolone acetate.

Change in appearance of the optic disc associated with lowering of intraocular pressure.

This report provides additional documentation that the appearance of the optic disc may improve after intraocular pressure is lowered in patients with glaucoma. Photographic records of one of the authors (GLS) were reviewed retrospectively. Seven previously unreported cases showing apparent improvement of the optic disc were found, and the patients' charts were reviewed.

Central corneal endothelial cell density after argon laser trabeculoplasty.

We report our experience using specular microscopy to perform endothelial cell counts in a series of 16 patients with bilateral, uncontrolled, primary open-angle glaucoma undergoing argon laser trabeculoplasty (ALT). Trabeculoplasty was performed in 20 eyes of these 16 patients. Untreated fellow eyes in 11 patients were used as controls for this series.

Formation of peripheral anterior synechiae following argon laser trabeculoplasty. A prospective study to determine relationship to position of laser burns.

One hundred eighteen eyes with primary open-angle glaucoma underwent argon laser trabeculoplasty . Laser burns were placed in the anterior trabecular meshwork (ATM) in 58 eyes and directly over Schlemm's canal in the posterior trabecular meshwork (PTM) in 60 eyes. Twenty-nine eyes received 100 burns and 89 eyes received 50 burns distributed equally over 360 degrees.

Acute intraocular pressure elevation after argon laser trabeculoplasty and iridectomy: a clinicopathologic study.

Trabeculectomy specimens excised from five patients with persistent, medically unresponsive elevation of pressure following argon laser trabeculoplasty and argon laser peripheral iridectomy were studied by light and electron microscopy. Histological examination disclosed macrophages, lymphocytes, activated trabecular endothelial cells, and tissue debris from trabecular beams. This inflammatory response and tissue debris initiated by laser treatment appears to be an important factor in the postoperative decompensation of the aqueous outflow system.

Focal pressure: a new method to encourage filtration after trabeculectomy.

One cause of failure of trabeculectomy is early closure of the sclerostomy with insufficient aqueous outflow and subsequent scarring of Tenon's capsule and conjunctiva. Ocular massage and other forms of manipulation of the scleral flap have been used in the past to enhance filtration in cases where full-thickness filtration procedures were performed, and they have been suggested for use with trabeculectomy as well. The authors propose a new method in which focal pressure is applied with an anesthetic-moistened applicator directly to the conjunctiva beside the edge of the scleral flap.

Variation of techniques on the results of argon laser trabeculoplasty.

Patients with uncontrolled open-angle glaucoma were treated with argon laser to the trabecular meshwork. These patients were divided into six groups. Each group of eyes had a slightly different technique of argon laser therapy.

Tapioca melanoma of the iris: a contribution to the fine structure and its significance.

A case of iris malignant melanoma, macroscopically classified as tapioca melanoma, was studied by electron microscopy. The tumor originated in the left eye of a patient, and a specimen was obtained during iridociclectomy. Two main types of cells were found: the differences between them concerned mainly the Golgi complex, mitochondria, RER and free ribosomes.
