BACKGROUNd ANd OBJECTIVES: To evaluate the outcomes of vitreoretinal surgery f or the ocular complications of Behet’s disease. PATIENTS ANd METhOdS: This re trospective study included 20 eyes of 15 patients with Behet’s disease (9 men , 6 women; mean age at surgery, 31.0±1.8 years; range, 21-44 years) who had un dergone vitreoretinal surgery for Behet’s disease at Ondokuz Mayis University , Faculty of Medicine, department of Ophthalmology, Samsun, Turkey, between Janu ary 2000 and September 2003. Postoperative visual acuity outcome, course of uvei tis, and complications were evaluated in all patients. RESULTS: Indications for surgery were vitreous opacities in 10 eyes (50%), cystoid macular edema in 5 ey es (25%), epiretinal membrane in 3 eyes (15%)-, and vitreous hemorrhage in 2 eyes (10%). At the last postoperative follow-up, visual acuity had increased 2 Snellen lines or more in 10 (50%) of 20 eyes. Cystoid macular edema completely improved in 3 (60%) of 5 eyes after vitrectomy. Uveitis attacks significantly decreased during follow-up (P=.015). Immunosuppressive treatment was stopped in 11 (73%) of 15 patients. Retinal detachment and phthisis were not observed in any eye. CONCLUSION: Vitreoretinal surgery may be useful in the treatment of pos terior segment complications of Behet’s disease.

To present the use of automated lamellar therapeutic keratoplasty (ALTK) for t he treatment of post-photorefractive keratectomy (PRK) corneal scarring and thi nning with significant residual myopia. Interventional case report. A patient wi th high myopia of-12 diopters previously underwent PRK that resulted in corneal scarring, myopic regression, moderate loss of best-corrected visual acuity, a residual refractive error of -6.50/-1.00 ×.175 degrees, and a remaining corneal thickness of 300 μm. ALTK was first performed to remove the scar and to augment corneal thickness, and a subsequent laser-assisted in-situ keratomi leusis (LASIK) procedure was performed to correct the residual myopia. ALTK effe ctively removed the corneal scar and augmented the corneal thickness to 639 μm. LASIK effectively treated the residual myopia, resulting in an unaided visual a cuity of 20/25 and a stable refractive error of plano/-0.50 ×40 degrees. The A LTK interface remained clear throughout the follow-up period of 26 months. ALTK may be a reasonable alternative to conventional penetrating keratoplasty in the treatment of post-PRK corneal scarring and thinning, with a moderate loss of b est-corrected visual acuity, and LASIK can be subsequently performed to correct the residual refractive error and achieve an excellent refractive and visual ou tcome.

Objective: We aim to quantify the magnitude of setup errors in intensity-modulated radiotherapy (IMRT) treated.h.ad and Neck cancer patients and recommend appropriate PTV margin. Methods: 60 patients with head and neck cancer required bilateral neck irradiation were planned and treated by simultaneous integrated boost IMRT technique either treated radically or postoperative. Patients undergoing image-guided radiotherapy (IGRT) each with once weekly scheduled cone beam computed tomography (CBCT). The 3d displacements, systematic and random errors were calculated. The appropriate PTV expansion was determined using Van herk’s formula. Results: Mean 3d displacement was 0.16 cm in the vertical direction, 0.14 cm in the horizontal direction and 0.16 cm in the longitudinal direction. Conclusion: Use of weekly CBCT allows the planning target volume (PTV) expansion to be reduced according to our setup. The appropriate clinical target volume (CTV)-PTV margin for our institute is 0.30 cm, 0.38 cm, and 0.33 cm in the horizontal, vertical, and longitudinal directions, respectively.

We found previously in a lesion study that the right-sided sector of the ventromedial prefrontal cortices (VMPCs) was critical for social/emotional functioning and decision-making, whereas the left side appeared to be less important. It so happened that all but one of the subjects in that study were men, and the one woman did not fit the pattern very well. This prompted a follow-up investigation, in which we explored the following question: does gender play a role in the development of defects in social conduct, emotional functioning and decision-making, following unilateral VMPC damage? We culled from our Patient Registry same-sex pairs of men or women patients who had comparable unilateral VMPC damage in either the left or right hemisphere. Two male pairs and one female pair were formed, and we included two additional women with unilateral right VMPC damage (8 patients in all). The domains of measurement covered social conduct, emotional processing and personality, and decision-making. We found a systematic effect of gender on the pattern of left-right asymmetry in VMPC. In men, there were severe defects following unilateral right VMPC damage, but not following left-sided damage. In women, there were defects following unilateral left VMPC damage; following right-sided damage, however, defects were mild or absent. The findings suggest that men and women may use different strategies to solve similar problems -e.g. men may use a more holistic, gestalt-type strategy, and women may use a more analytic, verbally-mediated strategy. Such differences could reflect asymmetric, gender-related differences in the neurobiology of left and right VMPC sectors.

PURPOSE: To define the clinical characteristics of atypical birefringence imag es and to describe a quantitative method for their identification. dESIGN: Prosp ective, comparative, clinical observational ***: Normal and glaucomato us eyes underwent complete examination, standard automated perimetry, scanning l aser polarimetry with variable corneal compensation (Gdx-VCC), and optical cohe rence tomography (OCT) of the macula, peripapillary retinal nerve fiber layer (R NFL), and optic disk. Eyes were classified into two groups: normal birefringence pattern (NBP) and atypical birefringence pattern (ABP). Clinical, functional, a nd structural characteristics were assessed separately. A multiple logistic regr ession model was used to predict eyes with ABP on the basis of a quantitative sc an score generated by a support vector machine (SVM) with ***: Sixt y-five eyes of 65 patients were enrolled. ABP images were observed in 5 of 20 ( 25%) normal eyes and 23 of 45 (51%) glaucomatous eyes. Compared with eyes with NBP, glaucomatous eyes with ABP demonstrated significantly lower SVM scores (Pd 0.03, respectively) and greater temporal, mean , inferior, and nasal RNFL thickness using Gdx-VCC; and a weaker correlation wi th OCT generated RNFL thickness (R2=.75 vs. 27). ABP images were significantly c orrelated with older age (R2=.16, P=.001). The SVM score was the only significan t (Pdictor of ABP images and provided.h.gh discriminating power betw een eyes with NBP and ABP (area under the receiver operator characteristic curve =0.98). CONCLUSIONS: ABP images exist in a subset of normal and glaucomatous eye s, are associated with older patient age, and produce an artifactual increase in RNFL thickness using Gdx-VCC. The SVM score is highly predictive of ABP images .

Event-related potentials (ERPs) were used in this study to investigate the neural correlates of prospective memory (PM) and vigilance. Twenty college or graduate students participated in this study. They were administered a PM and a vigilance task and physiological data were collected at the same time. Behavioral results showed that the RT associated with PM cues was longer than those associated with vigilance targets. ERP results showed that PM cues and vigilance targets did not show significant difference in the N2 but PM cues evoked greater N300 than vigilance targets, and vigilance targets evoked greater parietal positivity/P3 than PM cues, suggesting vigilance and PM have similar but also distinctive neural basis.
