Treatment of macular hole retinal detachment with silicone oil, with or without argon laser photocoagulation.

If the eyeball is filled with silicone oil after vitrectomy, the occlusion of the macular hole and the internal tamponade thus obtained cause the retina to become reattached. Unlike the results obtained with gas injection, occlusion and tamponade are permanent. If the regained visual acuity is less than 1/20, the edges of the macular hole are photocoagulated and the silicone oil withdrawn; if the regained visual acuity is better, the silicone oil is left in place without photocoagulation.

[Results of argon laser treatment of 100 eyes with open-angle glaucoma (trabeculoplasty, trabeculoretraction)].

One hundred phakic eyes of 76 patients with primary open angle glaucoma received argon laser therapy to the trabecular meshwork, a method, based on the works of James Wise, which we prefer to call trabecular retraction for two reasons: 1) the mechanical factor of trabecular tightening caused by the laser microscars and 2) to differentiate it from initial argon laser treatment in primary open angle glaucoma: trabeculopuncture. Argon laser trabecular retraction involves application to the entire pigmentary trabecular ring, just anterior to the scleral spur, of 100 evenly spaced non-penetrating burns, using a 50 microM. beam diameter with a pulse duration of 0,1 sec, and a power level adjusted to produce a minimum visible trabecular reaction. Laser treatment was performed on an out-patient basis using a three mirror Goldmann lens after topical anesthesia. Pre-laser anti-glaucoma medical treatment was continued unchanged during the follow-up period of this study, to assess accurately the effect of the laser treatment on intraocular pressure (IOP) without introducing the variable of changing medications. Treatment was applied to eyes with uncontrolled glaucoma on maximum tolerable medical therapy and, as such, candidates for surgery, eyes of patients unable to tolerate side effects of effective intensive medical therapy, and eyes with controlled open angle glaucoma to permit reduction of medical therapy. Mean pressure drop in the 100 eyes was 8,9 mmHg, the reduction of IOP being achieved between 3 and 6 weeks after the laser procedure. Surgery for glaucoma was avoided in 93% of the eyes. Pressure drop in 75% of treated eyes was between 4 and 11 mmHg, in 16% was 12 mmHg or more, and in 9% was 3 mmHg or less. Follow-up was for at least three months and in some cases extended to 15 months. These results and data from published reports suggest that the pressure drop obtained three months post-laser could be considered definitive, except in a very small percentage of eyes. Average intraocular pressure reduction in patients under 60 years was 8,3 mmHg and 88% of the eyes had a drop in IOP of 4 mmHg or more. In patients over 60 years, average intraocular pressure reduction was 9,3 mmHg and 93% of the eyes had a drop in IOP of 4 mmHg or more. The major complication in eyes with marked glaucomatous damage to their optic nerves is a possible rise in intraocular pressure following treatment. This post-laser increase in IOP was noted in 19 eyes but resolved either spontaneously or easily with medication. No visual field loss was observed in these eyes. Localized peripheral anterior synechiae were noted in 42 eyes, but these did not affect the success of the procedure.4

[Technique employing argon laser coagulation to obtain trabecular retraction].

A technique for treating primary open angle glaucoma by argon laser photocoagulation is described. Its elective action on the trabeculum and on trabecular "collapse" in the absence of any trabecular perforation suggested the name of "trabecular retraction" for this procedure. Its efficacy depends on very good visibility of the trabeculum through 360 degrees, on perfect focalization of the point of impact to 50 mu, and on the application of one hundred or so impacts distributed throughout 360 degrees. Any pretrabecular obstacle must be eliminated. Mean pressure drap obtained is 10 mmHg. Complications are minimal and results comparable or superior to those of surgery.

[Pars plana vitrectomy: causal affections, material employed, and approach in 1400 cases (author's transl)].

Isolated vitrectomy was employed in half of 1,400 cases operated upon, the other patients receiving an intra-ocular injection of silicone fluid. Emphasis is placed on the simplification undergone by the materials employed, the progress represented by the addition of an autonomous infusion for each instrument complementary to the vitrectomy, and the need for all ophthalmic surgeons, particularly those in training, to become familiar with the use of the vitreotome.
