Öğe Argon laser photocoagulation for recurrent hyphema caused by a rupture of Schlemm's canal(Slack Inc, 2001) Akkin, C; Uretmen, O; Emre, S; Ates, HÖğe Effect of corneal wetting solutions on corneal thickness during ophthalmic surgery(Elsevier Science Inc, 2002) Emre, S; Akkin, C; Afrashi, F; Yagci, APurpose: To measure the changes in corneal thickness with wetting solutions used in ophthalmic surgery. Settings. Ege University, School of Medicine, Department of Ophthalmology, Izmir, Turkey. Methods. Thirty-one adult pigmented rabbits that weighed about 2.5 kg each were anesthetized with pentobarbital sodium. The rabbits were randomly divided into 3 groups to receive 3 wetting solutions: Group 1, Ringer's lactate; Group 2, balanced salt solution (BSS(R)); and Group 3, BSS with glutation (BSS Plus(R)). The solutions were dropped on the right cornea of the rabbits at a rate of 6.0 cc in 12 minutes using an intravenous infusion pump. Corneal thickness was measured by ultrasonic pachymetry before and after the procedure, and the between-group changes in corneal thickness were compared. Results: The corneal thickness before and after the procedure was 361.27 mum +/- 19.3 (SD) and 380.00 +/- 25.0 mum, respectively, in Group 1 (P = .000); 372.10 +/- 18.8 mum and 388.60 +/- 24.1 mum, respectively, in Group 2 (P = .003); and 358.10 +/- 26.5 mum and 360.10 +/- 24.1 mum, respectively, in Group 3 (P = .316). Conclusion: As a corneal wetting solution, BSS Plus resulted in significantly fewer changes in corneal thickness than Ringer's lactate or BSS. This should be considered in cases involving long intraocular surgery.

After a capsulorhexis is performed, a deep cavity in the lens of an enucleated sheep eye is formed by phacoemulsification through a lateral incision. An undamaged human cataractous lens nucleus obtained by extracapsular cataract extraction is inserted in the preformed cavity, resting in the center of a cortex cushion. Phacoemulsification training is performed through a corneal tunnel incision. The experimental model is prepared with a human cataractous lens nucleus of the preferred hardness, simulating nuclear phacoemulsification in humans.

Five patients were enrolled in the study. All patients had a vertical deviation greater than 15 PD and severe limitation of upgaze. Post- surgical follow up was at least 12 months. Mean pre- operative vertical deviation decreased from 24 PD to 2.4 PD at 1 year postoperatively. Two patients were orthotropic and 3 patients had residual hypotropia ranged from 2 PD to 6 PD. Upgaze limitation relieved significantly in the post-operative period. As we obtained satisfactory results without any significant complications in our patients, we advocate that recession of the IR with adjustable loop suture under topical anesthesia is safe and effective in patients with thyroid ophthalmopathy.Öğe Recession of the inferior rectus muscle under topical anesthesia in thyroid ophthalmopathy(Slack Inc, 2002) Kose, S; Uretmen, O; Emre, S; Pamukcu, KPurpose: To evaluate the results of inferior rectus muscle recession with adjustable loop suture under topical anesthesia for vertical deviations secondary to thyroid ophthalmopathy. Patients and Methods: Five patients with a vertical deviation greater than 15 PD and severe limitation of upgaze were enrolled in the study. Before proceeding with corrective strabismus surgery, we waited at least 6 months after stabilization of ocular alignment and normalization of thyroid chemistries. All patients underwent inferior rectus muscle recession with adjustable loop suture under topical. anesthesia. The postsurgical follow-up was at least 12 months. Results: Preoperatively, the mean vertical deviation was 24 PD. At 1 year postoperatively, it had decreased to 2.4 PD. Two patients were orthotropic and 3 patients had residual hypotropia ranging from 2 to 6 PD. The limitation of upgaze was relieved significantly in the postoperative period. Two patients had minimal limitation of downgaze, but none complained of diplopia in the primary or reading positions. Surgery did not trigger a flare-up of orbital inflammation in the early postoperative period. Conclusion: We advocate that recession of the inferior rectus muscle with adjustable loop suture under topical anesthesia is safe and effective in patients with thyroid ophthalmopathy.Öğe Temel göz muayeneleri ve uygulamaları için pratik bir model, T Oft Gaz 31, 441-446, 2001(2001) Akkın, Cezmi; Emre, S; Erakgün, Tansu; Kerci, Gökhan…Öğe Treating keratoconus with intacs corneal ring segments(Slack Inc, 2005) Hellstedt, T; Makela, J; Uusitalo, R; Emre, S; Uusitalo, RPurpose: To asses the safety and efficacy of Intacs inserts for the treatment of mild to moderate keratoconus. Methods: In a nonrandomized prospective clinical trial, 50 eyes of 37 patients with mild to moderate keratoconus were implanted with asymmetrical pairs of Intacs segments. Patients were interviewed and observed preoperatively and 24 hours, 1 week , 1, 3, 6, and 12 months postoperatively. Main outcome measures were uncorrected visual acuity (UCVA), best spectacle-corrected visual acuity (BSCVA), refraction, satisfaction with vision and trouble with vision, Visual Function-7 score, and surgically induced change in corneal astigmatism. Results: Of the 50 operations performed, 92% were successful. Mean follow-up was 6.3 +/- 3.2 months. in 4 (8%) eyes, both Intacs segments were removed. In addition, 7 refractive adjustments in 7 eyes were performed successfully to improve visual and surgical outcome. Both BSCVA and UCVA improved throughout follow-up. Visual functioning index improve from 61.6 +/- 21.1 to 80.8 +/- 22.5, and the percentage of satisfaction with vision improved from 24.3% to 87.5% at 12 months. Vector analysis of astigmatism correction showed that the mean change in corneal astigmatism was 2.9 +/- 2.9 D at 6 months postoperatively. By selecting patients in whom astigmatism correction was best (index of success > o.t), an analysis was performed to determine individual factors important in successful surgery. Preoperatively these 11 (22%) eyes did not differ significantly from the remaining eyes and the only significant value was low K readings in the flat axis. Conclusions: Asymmetric Intacs placement improves BSCVA and UCVA and reduces astigmatism in patients with mild to moderate keratoconus. The procedure of Intacs placement is safe and effective. The change in astigmatism correction is unpredictable.
