    Gentian violet solution for staining the anterior capsule
    (Amer Soc Cataract Refractive Surgery, 2000) Ünlü, K; Askünger, A; Söker, S; Kilinç, N; Karaca, C; Erdinc, M
    Purpose: To evaluate the histopathological changes after injecting gentian violet solution into the anterior chamber of rats and to describe a technique that uses gentian violet to allow a clear view of the anterior capsule during continuous curvilinear capsulorhexis (CCC) in human eyes with white mature cataract. Setting: Department of Ophthalmology, University of Dicle, Diyarbakir, Turkey. Methods In this masked, experimental study (first stage), 0.05 mL of gentian violet 0.01% or 0.001% solution or balanced salt solution (BSS(R)) (control group) was injected into the anterior chamber of 30 eyes of 30 Wistar albino rats. One, 24, and 48 hours after injection, 4 eyes in each group and 2 eyes in the control group were enucleated, and histopathological examination was performed. In the second stage, these solutions were used for staining the anterior capsule in the 18 human eyes with white mature cataract. The success rate of CCC and intraoperative and postoperative complications were evaluated. Results: Histopathological examination revealed no pathology in any group. A CCC was completed in all cases. No intraoperative or postoperative complications were observed in human eyes except mild corneal edema and mild inflammatory reaction in the anterior chamber that improved within 1 week. Mean follow-up was 3.4 months. Visualization of the anterior capsule was better with gentian violet 0.01% solution. Conclusions: Gentian violet solutions at 0.01% and 0.001% concentrations had no evident toxic effect that caused significant histopathological changes. The staining technique was practical and helped the surgeon visualize the anterior capsule. However, gentian violet may have adverse effects that lead to corneal edema.

    Mitomycin C primary trabeculectomy with releasable sutures in primary glaucoma
    (Elsevier Science Inc, 2000) Ünlü, K; Aksünger, A; Söker, S; Ertem, M
    Purpose: To evaluate the effects of mitomycin C and a releasable suture technique on outcomes of primary trabeculectomy in primary glaucoma patients. Methods: A prospective analysis of patients who underwent primary trabeculectomy with a mitomycin C concentration of 0.2 mg/mL for 2 minutes. For closing the scleral flap, releasable sutures were used in 18 patients (17 eyes), Group 1, or permanent sutures in 18 patients (20 eyes), Group 2. Clinical outcome factors including postoperative intraocular pressure (IOP), visual acuity, and incidence of complications were determined. Results: The mean follow-up periods were 8.1 +/- 1.3 months in Group 1 and 8.3 +/- 1.3 months in Group 2. The postoperative reduction in IOP was highly significant (P < .0001) at all time intervals in both groups. In all measurement of IOP before the second week, mean IOP in Group 2 was found significantly lower than the mean IOP in Group 1 (P = .01). No statistically significant differences were found between the groups at later mean IOP measurements. At the last visit, the complete success rate was 88.8% in Group 1 and 85.0% in Group 2. No serious complications such as hypotonous maculopathy were observed in ally patient. Conclusion: Primary trabeculectomy with mitomycin C in eyes with primary glaucoma showed effective IOP pressure reduction. There were no cases of serious complications. In the early postoperative period IOP was controlled better in the releasable suture group. (C) 2000 Japanese Ophthalmological Society.

    Prospective evaluation of the argon laser treatment of trachomatous trichiasis
    (Elsevier Science Inc, 2000) Ünlü, K; Aksünger, A; Söker, S; Karaca, C; Bilek, K
    Purpose: To evaluate the effectiveness of argon laser photocoagulation for the treatment of trachomatous trichiasis. Methods: This report presents a prospective, non-masked study of 22 patients (36 eyelids) with trachomatous trichiasis treated with the argon laser. Each abnormal lash was treated with a beam of 50- to 200-micron spot size, for 0.2 seconds, and 1 to 1.2 watts power. In 30 lids (83.3%) infiltration anesthesia was used and in 6 lids (16.7%) no anesthesia was used. Results: Successful treatment with no evidence of recurrence was achieved in 55.5% of lids after one laser session. The remaining 44.5% of the lids required two or three sessions. The final success rate of the method was 88.9%. No complications were observed. The mean follow-up time was 10.6 months. Conclusion: Argon laser photocoagulation is an effective and safe method far the treatment of trachomatous trichiasis. (C) 2000 Japanese Ophthalmological Society.
