Peripheral iridectomy via a corneal section: a follow-up study.

A method of performing peripheral iridectomy through a corneal incision is described. Of the fifty patients reviewed, there were no immediate postoperative complications. In the follow-up period the incidence of lens opacities associated with visual loss was 16% and 21% in the prophylactic and therapeutic groups respectively. The percentage of posterior synechiae in the prophylactic group was 16%. Ninety-three percent of patients had a visual acuity of 6/12 or better at the end of the follow-up period. When compared with the results of previous surveys, the method is as safe as the ab externo approach. The technique avoids bleeding and leaves the bulbar conjunctiva undamaged and available for any subsequent drainage procedure.

Laser iridectomy--a technique for blue irises.

A two-step technique for laser iridectomy in light blue irises is described, which simplifies penetration of these irises and allows success rates approaching 100%. Step one utilizes a high energy, long duration, predominantly thermal laser burn that destroys overlying iris stroma. In step two, the laser energy is reduced and exposure time is shortened to facilitate removal of remaining pigment epithelium.

AB interno iridectomy combined with pars plicata lensectomy.

We applied a pressure cuff onto the soft bag to increase the infusion pressure of the Peyman's miniphage, so that with it the pars plicata lensectomy and membranectomy became safer. We also developed ab interno iridectomy combined with pars plicata cataract surgery using the miniphage or wide-angle cutter vitrophage. By this new technique, angle closure glaucoma was prevented without excessive vitrectomy. Neither major intraoperative nor postoperative complications were encountered.

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.

Pigmented corneal implants: a surgical treatment for iridectomy related optical complications.

Initial evaluation in rabbits demonstrates that corneal implants made from prolene and nylon sutures flattened into strips appear promising as a means of covering diplopia or glare-inducing iridectomies. Two-month follow-up studies showed the implants to be well tolerated in the corneal stroma. Results of the studies suggest that black prolene films of 50 to 70 micrometers in thickness, contoured to follow the corneal curvature, would be the ideal configuration for such implants.

[Use of contact lenses during argon laser iridectomies (author's transl)].

Advantages appear to be gained by the use of a specific contact lens during argon laser iridectomy. On the one hand, the energy level is increased on the iris and diminished on the retina. On the other hand, coagulation is directed near the iris base and far from the posterior pole. Specifications of a new contact lens are presented.

Self-sealing incision for peripheral iridectomy.

A peripheral iridectomy was done in 42 cases using an incision perpendicular to the cornea at the anterior edge of the conjunctival epithelium. No conjunctivalflap or sutures were used. No attempt was made to reform the anterior chamber by irrigation of fluid through the incision. The results were satisfactory.

Inferior peripheral iridectomy in patients receiving silicone oil. Rates of postoperative closure and effect on oil position.

BACKGROUND: Silicone oil tamponade is used in treating retinal detachments, but silicone-associated complications remain frequent. Keratopathy and acute pupillary block glaucoma are related to migration of silicone oil into the anterior chamber. Since 1985, many surgeons have created an inferior peripheral iridectomy (PI) at the time of surgery to prevent forward migration of the oil, but the rate of postoperative closure of the PI and the effect on oil position have not been well defined. METHODS: The charts of 292 patients undergoing silicone oil surgery were reviewed. The status of the PI and the oil position were determined throughout the postoperative period. RESULTS: Postoperative closure of the PI occurred in 40 (33%) of 121 aphakic eyes in the early postoperative period. Forward migration of the oil was highly associated with closure of the PI (32/40, 80%). Conversely, forward oil migration occurred in only 11% (9/81) of eyes with patent PIs. The rate of PI closure was significantly greater for patients with proliferative diabetic retinopathy (21/40, 52%) than for patients with proliferative vitreoretinopathy (11/58, 19%). CONCLUSION: Postoperative closure of the PI occurred in a significant fraction of eyes undergoing silicone oil surgery, was highly correlated with forward oil migration, and occurred most frequently in eyes with proliferative diabetic retinopathy.

[Iris tuberculosis. A propos of a case diagnosed by iridectomy].

Ocular tuberculosis is currently rare in developed countries. We report a case of tuberculous nodular anterior uveitis which revealed primary tuberculosis in a 2-year old girl. This diagnosis was established on microscopic examination of a surgical iridectomy specimen. Thus, a metastatic retinoblastoma was eliminated. The subsequent clinical investigations showed that the girl's father had active pulmonary tuberculosis.

Performing peripheral iridectomy via a scleral tunnel incision: a new approach.

A peripheral iridectomy (PI) is sometimes difficult to perform through a sclero-corneal tunnel. This study evaluated the effectiveness and safety of a newly proposed technique for performing a PI. The results showed that a PI can be easily performed through a sclero-corneal tunnel, employing this technique.

The use of the consensual light reflex as an aid to performing laser peripheral iridectomy in patients with pigment dispersion syndrome and pigmentary glaucoma.

PURPOSE: The authors explore an alternative method of performing laser peripheral iridectomy (LPI) in patients with pigment dispersion syndrome and pigmentary glaucoma (PDS/PG) who are high myopes and therefore at increased risk of developing retinal detachment. METHODS: Four myopic patients with PDS/PG had LPI performed in one eye. A transilluminator was held up to the opposite eye to provide pupillary constriction via the consensual light reflex. No miotics were used. RESULTS: All LPIs were easily performed without complications. CONCLUSION: The authors present an alternative method to the standard use of pilocarpine for LPI theoretically to decrease further the incidence of retinal detachment in populations predisposed to it.
