Conventional buckling surgery or primary vitrectomy with silicone oil tamponade in rhegmatogenous retinal detachment with multiple breaks.

BACKGROUND: There is controversy about the most appropriate operating methods for complicated rhegmatogenous retinal detachment (RD) including multiple tears, and surgical techniques may be changed according to the preference of the surgeon. 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.

Negative social bias against children with strabismus.

PURPOSE: 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.

Effect of corneal wetting solutions on corneal thickness during ophthalmic surgery.

PURPOSE: 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); and Group 3, BSS with glutation (BSS Plus). 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 microm +/- 19.3 (SD) and 380.00 +/- 25.0 microm, respectively, in Group 1 (P =.000); 372.10 +/- 18.8 microm and 388.60 +/- 24.1 microm, respectively, in Group 2 (P =.003); and 358.10 +/- 26.5 microm and 360.10 +/- 24.1 microm, 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.

Color Doppler imaging of choroidal circulation in patients with asymmetric age-related macular degeneration.

We 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.

Comparison of achromatic and blue-on-yellow perimetry in patients with resolved central serous chorioretinopathy.

Central serous chorioretinopathy (CSCR) is a disorder characterized by the serous detachment of the sensory retina in the posterior pole. Although CSCR usually resolves spontaneously, the patients may notice residual visual deficits, despite recovering normal visual acuity. The aim of this study is to compare the blue-on-yellow perimetric parameters with conventional automated perimetric parameters in the detection of visual deficits in patients with resolved CSCR. Eighteen patients who had spontaneous recovered from CSCR were enrolled this study. All subjects were examined twice with each type of perimetry. Wilcoxon test was used for statistical analysis. The achromatic perimetric mean deviation values were significantly higher in patients with CSCR than in the control group, while statistically a significant difference was determined for all of blue-on-yellow perimetric values. In conclusion the loss of central retinal sensitivity remains after resolution of the CSCR even if the visual acuity has recovered to normal. Blue-on-yellow perimetry is more sensitive than achromatic perimetry to reveal this central sensitivity loss.
