Paroxysmal Positional Vertigo

The results of long-term follow-up after surgical treatment of two patients with intractable benign paroxysmal positional vertigo are reported. Argon laser irradiation of the blue-lined posterior and lateral semicircular canals in one patient, and of only the posterior canal in the other was performed seven and six years ago, respectively. Argon laser irradiation was carried out 10 times in succession three mm along the canal to occlude it. The power applied each time was 1.5.W on the dial of the laser device for 0.5.sec. Relief of vertigo was noted on the second post-irradiation day. There has been no recurrence of vertigo in these patients.

Iridocorneal Angle

Plateau iris syndrome (PIS) is a frequent cause of angle closure. Argon laser peripheral iridoplasty (ALPI) has been proposed in PIS to widen the iridocorneal angle. The objective of the present study was to perform a systematic review of the available studies evaluating the efficacy of ALPI on intraocular pressure (IOP), iridocorneal angle opening and the number of medications in patients with chronic angle-closure associated with PIS. One prospective and seven retrospective studies with a minimum 1 month of follow-up were included. Although ALPI seemed to lower IOP, to decrease the number of topical antiglaucoma medications and widen the iridocorneal angle shortly after the procedure, there is no current evidence of long-term efficacy. To date, there is no robust scientific evidence to advocate ALPI as a treatment for chronic angle-closure caused by PIS.

AbstractFrom a cohort of 35 patients with hereditary haemorrhagic telangiectasia (HHT), 12 patients have undergone closure of the one or both nasal cavities during the last three years for refractory epistaxis. All had failed other forms of treatment including hormone therapy, laser coagulation and septodermoplasty. All patients were available for follow-up at six months or longer. In all patients where complete closure was achieved (11 out of 12) bleeding ceased completely from the operated side.

A total of 182 patients (95 men and 87 women) aged 15-49 years with insulin-dependent diabetes mellitus were treated using argon laser coagulation. Late results of laser therapy were followed up for 6 months to 3 years. In the patients with nonproliferative diabetic retinopathy (DR) on the fundus oculi the improvement consisted in partial resolution of solid exudative foci and retinal hemorrhages in 20%o of cases. In patients with preproliferative DR, soft exudative foci partially resolved and the number of retinal hemorrhages and microaneurysms decreased in 17%o of cases. In patients with proliferative DR, regressive development of proliferative tissue, desolation of newly formed vessels, and resolution of preretinal hemorrhages were observed in 13.9%o of cases. Stabilization for 3 years was attained in 75%) of patients with nonproliferative and proliferative and in 72.5%o of those with preproliferative DR.

Argon laser radiation is used to treat congenital and acquired vascular lesions of the head and neck. Thirteen patients requiring a total of 36 treatments were followed up for a minimum of 1 year to assess the response of the vascular lesion to argon ion radiation. Of the 13 patients, 10 had an excellent result, with the lesion no longer being identifiable. Three of the patients had residual but minimal color remaining in the lesion. There were no complications or hypertrophic scars after 1 year of follow-up. The laser parameters used and the surgical technique followed are outlined.

Purpose. To develop an optimal algorithm for the management of patients with operated neovascular uncompensated glaucoma. Material and methods. 2 patients with operated secondary neovascular glaucoma of stage III-c. In the combined sequential therapy, the anti-VEGF medication Ranibizumab (0.5 mg) was used, laser coagulation of residual newly formed vessels, laser reconstruction in the surgical area, contact transcleral cyclolazercoagulation, and laser coagulation of the peripheral parts of the retina were performed. Results. The combined sequential treatment, combined with the appointment of antihypertensive drugs in drops, allowed to stabilize the level of IOP. IOP indicators remained at the level of normal values during 1 year of follow-up. Conclusion. The use of combined laser technologies and anti-VEGF therapy makes it possible to potentiate and prolong the hypotensive effect in the treatment of patients with operated secondary refractory neovascular glaucoma. Key words: operated neovascular glaucoma, anti-VEGF, combined laser treatment.

In a retrospective study 97 patients with glaucoma and 16 with ocular hypertension were examined with regard to intraocular pressure (IOP) after extracapsular cataract extraction with implantation of a posterior chamber lens. During the follow-up 39 cases dropped out but 63 glaucoma patients and 11 patients with ocular hypertension were followed for three years. Compared to preoperative IOP 59% of the patients treated previously with Argon laser trabeculoplasty (ALT) had an IOP rise of > 10 mm Hg the day after surgery. The corresponding proportion among medically treated patients was 34% (P=0.01). A pressure rise of > 10 mm Hg was less frequent among patients treated with one drug than among those treated with two or three (P=0.05). During follow-up eight patients had a pressure rise which could not be controlled medically and they had to undergo additional ALT or surgery. All eight had been treated with ALT or with glaucoma filtering surgery prior to the cataract operation. After three years observation of 63 of the glaucoma patients, 63% were having less medical therapy than preoperatively, 30% an equal amount and 7% more; 49% (31 of 63) were still without any therapy. In the group of patients who preoperatively were only treated medically, no definite increase in therapy was needed in the long term.
