Öğe Alcohol liberates dye of syringes(Kluwer Academic Publ, 1996) Kayikcioglu, O; Akkin, CForeign particles may contaminate intraocular surgery and have a role in postoperative inflammation. Irrigation solutions, viscoelastics, air and instruments introduced into the eye may carry in a number of organic or inorganic, inert or reactive foreign material. Dye of colored indicators on syringes may also behave as an unrecognized contaminant. This dye material is easily released from syringes by exposure to alcohol. The significance of dye contamination and possible outcomes were discussed.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 Coexistence of Intraocular Eyelashes and Anterior-Chamber Cyst After Penetrating Eye Injury - a Case Presentation(Kluwer Academic Publ, 1994) Kose, S; Kayikcioglu, O; Akkin, C; Yagci, A; Basdemir, GWe herein describe a patient in whom two intraocular eyelashes and an anterior chamber cyst embedded into the anterior surface of the iris was detected following penetrating eye injury. After a one year asymptomatic period, the patient was hospitalized because of uveitic reaction in the anterior chamber which may be due to cyst development. The lashes and cyst were removed surgically, and examined pathologically. There was no complication in one year follow-up period.Öğe Color Doppler imaging in glaucoma patients with asymmetric visual field loss(Amer Soc Contemporary Ophthalmology, 2000) Ates, H; Uretmen, O; Killi, R; Akkin, C; Andac, KWith color Doppler imaging, we attempted to determine whether glaucoma patients with asymmetric visual field losses had evidence of asymmetric blood flow velocities in the central retinal artery despite similar intraocular pressure (IOP) curves in both eyes. We found that eyes with more severe visual field damage had an increased local resistance to blood flow in the central retinal artery. Thus vascular factors might have important roles in the pathogenesis of primary open-angle glaucoma.Öğe Color Doppler imaging of choroidal circulation in patients with asymmetric age-related macular degeneration(Karger, 2003) Uretmen, O; Akkin, C; Erakgum, T; Killi, RWe aimed at evaluating the possible role of choroidal perfusion abnormalities in the development of choroidal neovascularisation (CNV) in patients with age-related macular degeneration (AMD). Twenty-six patients who had non-exudative AMD in the first eye and CNV secondary to AMD in the fellow eye were enrolled. Blood flow velocities, vessel pulsatilities and resistivities were measured from ophthalmic artery, nasal and temporal posterior ciliary arteries using colour Doppler imaging. Systolic and diastolic velocities were lower in eyes with CNV for all vessels, except for the systolic velocity of the nasal posterior ciliary artery (p >0.05). Pulsatility and resistivity indices were higher in eyes with CNV for all vessels. This difference was statistically significant for the resistivity index of the nasal and temporal posterior ciliary arteries (p = 0.032 and p = 0.021, respectively) and the pulsatility index of the nasal posterior ciliary artery (p = 0.035). We have shown that in patients with AMD choroidal blood flow is more impaired in the eyes with CNV than in the fellow eyes.Öğe Color Doppler imaging of choroidal circulation in patients with asymmetric age-related macular degeneration(Karger, 2003) Uretmen, O; Akkin, C; Erakgum, T; Killi, RWe aimed at evaluating the possible role of choroidal perfusion abnormalities in the development of choroidal neovascularisation (CNV) in patients with age-related macular degeneration (AMD).

In this retrospective study, we compared the surgical results of conventional buckling surgery and vitrectomy with silicone oil tamponade for rhegmatogenous (RD) with multiple breaks. Methods: Thirty patients who underwent scleral buckling surgery (group 1) and 22 patients who underwent pars plana vitrectomy with silicone oil tamponade (group 2) as the primary surgery for rhegmatogenous RD with multiple breaks were included in this study. The follow-up period was longer than 6 months after surgery. The anatomical success rates and complications were evaluated for both groups. Results: Retinal reattachment was achieved in 24 of 30 eyes (80%) in group 1 and in 20 of 22 eyes (90.9%) in group 2 after the initial surgery. In group 1, subretinal hemorrhage developed due to the drainage of subretinal fluid in 2 eyes (6.6%) intraoperatively. Elevated intraocular pressure (3.3%), ocular motility disturbances (13.2%), and proliferative vitreoretinopathy (3.3%) were seen in the postoperative period. In group 2, iatrogenic breaks (7.3%) and lens damage (9.09%) occurred during the operation. Macular pucker (4.5%), postoperative cataract progression (22.7%), ocular hypertension (9.09%) and PVR (9.09%) were noted postoperatively. Conclusions: Both surgical procedures can achieve favorable and comparable anatomic outcomes in the majority of patients in the treatment of RD with multiple breaks. Intra-and postoperative complications are different in the two procedures.Öğe Determining fluid level in a translucent eye-drop bottle: Transillumination by penlight(Kluwer Academic Publ, 1997) Kayikcioglu, O; Akkin, C; Ates, HWe describe an easy way to determine eye-drop contents in translucent bottles. Transillumination of eye-drop bottles from behind or the bottom by using a penlight clearly defines the fluid levels. The described procedure may prevent disposal of eye-drop bottles containing useful amounts of medication and prevent Ophthalmologists and Patients unexpectedly coming across an empty bottle.Öğe 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.

This instrument helps to divide the lens nucleus or its fragments into small pieces and thus reduces time and ultrasound energy.Öğe Management of the posterior segment foreign bodies with a simple snare(Lippincott Williams & Wilkins, 2003) Erakgun, T; Akkin, C; Mentes, JÖğe Management of the posterior segment foreign bodies with a simple snare(Lippincott Williams & Wilkins, 2003) Erakgun, T; Akkin, C; Mentes, JÖğe Marked MVR knife for vitreoretinal surgery(Lippincott Williams & Wilkins, 2003) Akkin, C; Erakgun, TÖğe Marked MVR knife for vitreoretinal surgery(Lippincott Williams & Wilkins, 2003) Akkin, C; Erakgun, TÖğe Negative social bias against children with strabismus(Blackwell Munksgaard, 2003) Uretmen, O; Egrilmez, S; Kose, S; Pamukcu, K; Akkin, C; Palamar, MPurpose: To determine whether the presence of noticeable strabismus creates a negative social bias against children. Methods: Photographs of two boys and two girls were digitally altered to create photographs of the same child in orthotropic, esotropic and exotropic states. Elementary school teachers rated their perceptions of the children's personal characteristics (using a 10-item list of personal characteristics) based on their responses to these whole-face photographs. The participants were also asked to answer five questions related to the first impressions created by the photographs. Results: Children with esotropia and exotropia were rated more negatively than orthotropic children on all 10 characteristics. Children with esotropia were rated more negatively than those with exotropia on most of these characteristics. Conclusions: Children with noticeable strabismus are viewed negatively. Hence, correction of strabismus may provide psychosocial benefits even when there is no hope of improving visual function.Öğe Negative social bias against children with strabismus(Blackwell Munksgaard, 2003) Uretmen, O; Egrilmez, S; Kose, S; Pamukcu, K; Akkin, C; Palamar, MPurpose: To determine whether the presence of noticeable strabismus creates a negative social bias against children.

The suturing begins from inside any of the wound tips in a clockwise direction. Suture placement proceeds in a counterclockwise direction by the adjacent wound limb, while the suture passes are all in clock-wise direction. Finally, a star-shaped suture is achieved with the knot self-buried in the corneal stroma at the initial entry site. This is a continuous suture, of which tractional forces direct to the center of the wound providing good apical apposition for stellate lacerations. This suture technique can be an alternative for the reconstruction of stellate corneal lacerations.Öğe Serum and Aqueous-Humor Sialic-Acid Levels In Behcets-Disease(Lippincott-Raven Publ, 1990) Yagci, A; Karcioglu, Za; Akkin, C; Andac, K; Cimrin, D; Onat, TÖğe A simple "lasso" for intraocular foreign bodies(Slack Inc, 1999) Erakgun, T; Ates, H; Akkin, C; Kaskaloglu, MThree patients had foreign bodies in their anterior chambers following penetrating ocular injuries. These foreign bodies were removed by a closed chamber technique using a simple loop. The loop was created by a 22-gauge intravenous cannula and a 7-0 polypropylene suture. Retained cilia in one patient and metallic foreign bodies in two patients were removed using this intraocular "lasso.'' Sutures were not placed at the incision sites at the end of the surgery. This is an inexpensive and easy to prepare technique that introduces minimal surgical trauma. In addition, two hands are not needed for loop manipulation. This technique may be an excellent alternative for removal of small intraocular foreign bodies.
