Abstract
PURPOSE To evaluate the outcomes of micropulse transscleral laser therapy (MP-TLT) in patients with uncontrolled glaucoma and prior glaucoma aqueous tube shunt. METHODS In this single‑center, retrospective, interventional case series, eyes that underwent MP-TLT and had prior glaucoma aqueous tube shunt surgeries were included. The Cyclo Glaucoma Laser System (IRIDEX Corporation, Mountain View, CA, USA) with the MicroPulse P3 probe (version 1) was used. Post‑operative data were collected at day 1, week 1, and months 1, 3, 6, 12, 18, 24, 30 and 36. RESULTS A total of 84 eyes (84 patients) with mean age of 65.8 ± 15.2 years and with advanced glaucoma (baseline mean deviation -16.25 ± 6.80 dB and best-corrected visual acuity 0.82 ± 0.83 logMar) were included in the study. Baseline mean IOP was 19.95 ± 5.6 mm Hg with a mean number of medications 3.39 ± 1.02. There were statistically significant differences in IOP between baseline and all follow-up visits (p < 0.01 for all). The mean percentage of IOP reduction between baseline and different follow-up visits ranged from 23.4% to 35.5% (p < 0.01). There was a significant reduction of visual acuity (≥ 2-lines) at 1 year (30.3%) and 2 years (76.78%). There was a statistically significant reduction in the number of glaucoma medications between baseline and all follow-up visits after postoperative week 1 (p < 0.05 for all). No severe complications including persistent hypotony and related complications were observed. At the last follow-up visit, only 24 (28%) eyes out of 84 eyes remained in the study. CONCLUSION MP-TLT is an effective treatment for reducing IOP and decreasing the number of medications in patients with advanced glaucoma and prior glaucoma aqueous tube shunt.

Abstract
Purpose Using demographic, clinical, visual field, and optical coherence tomography (OCT) variables to study the association of 5-year glaucomatous progression in glaucoma suspect eyes. Patients and methods This is a retrospective longitudinal clinical study. Inclusion criteria consisted of glaucoma suspect eyes (i.e., concerning cup-to-disk ratio and/or intraocular pressure (IOP) >21 mm Hg), age ≥ 30 years old, follow-up time of 5 years, best-corrected visual acuity (BCVA) of 20/100 or better, spherical equivalent (SE) higher than 8 diopters and an astigmatism less than 3 diopters. Eyes with glaucoma—determined by two consecutive, reliable visual field tests—were excluded, as well as any eyes with any clinically significant retinal or neurological disease. The percentage of glaucoma suspect eyes, which progressed to glaucoma within a 5-year period, was calculated. Study subjects were divided into the following groups: eyes that progressed to glaucoma and those that did not. Results In the 288 patients which we looked at, 365 total eyes, 323 eyes had concerning cup-to-disk ratio and 42 had ocular hypertension. Bivariate analysis showed that the eyes which progressed to glaucoma had significantly worse mean deviation, increased pattern standard deviation (PSD), and less visual field index (VFI). Our bivariate analysis also showed a thinner average, superior and inferior retinal nerve fiber layer thickness (RNFL), and more severe average, superior, and inferior RNFL damages (i.e., color grading scale) at baseline. Logistic regression analysis showed that only PSD and severe inferior RNFL damage (i.e., red color) to be significantly associated with 5-year glaucomatous progression. Conclusion Segmental RNFL damage and pattern standard deviation are associated with 5-year glaucomatous progression in glaucoma suspect eyes.

Abstract
Background
Joint manifestations during chronic inflammatory bowel diseases (IBD) represent the most frequent extra digestive manifestations, dominated by spondylarthropathy, isolated sacroillitis and peripheral rheumatism. We conducted a retrospective study of 9 cases of IBD collected in the pediatric services of the CHU MOHAMMED VI of Oujda over a 4 year period from July 2017 to March 2021.The objective of our study is to describe the joint manifestations in inflammatory bowel diseases in children.
Materials and methods
This is a retrospective study of 9 cases of IBD collected in the pediatric services of the CHU MOHAMMED VI of Oujda over a 4-year period from June 2017 to March 2021.
All these parameters were collected on operating sheets and reported on ExcelThe data were collected from the files registered in a pediatric hospitalization register
Results
Our study includes 9 patients with male predominance in 60% of cases, the prevalence of joint manifestations was 45% of which 3/4 of cases are in Crohn's disease and 1/4 of cases in UC.Axial joint involvement was 25% in Crohn's disease while joint involvement was peripheral in 75% of which 2/3 in Crohn's and 1/3 in UC.Peripheral involvement affects the large joints in all patients with a bilateral character. With a biological inflammatory syndrome in which the CRP was >50 mg/l and the VS more than 30All patients received corticotherapy and analgesics in 25% of cases. The evolution was marked by a good clinical and biological improvement with an average delay of 10 days.
Discussion
Ulcerative colitis (UC) and Crohn's disease (CD) are chronic cryptogenetic inflammatory bowel diseases (IBD). In addition to intestinal involvement, these IBDs are associated in 20% to30% of cases with extra digestive manifestations, with joint manifestations being the most frequent. There are essentially two types: Peripheral attacks which are the most frequent (8–20% of patients) especially during Crohn's disease; All joints can be affected, but most often asymmetric oligoarthritisAxial involvement includes sacroiliitis (SI) and ankylosing spondylitis (SpA) SI is more prevalent than SpA in both UC and CD Treatment of joint manifestations involves rest and exercise% tocontrol spinal stiffening in axial involvement; and analgesics Close collaboration between gastro-pediatricians and pediatric rheumatologists is the key to optimal management of the extra-digestive manifestations of IBD.
Conclusion
Joint involvement plays an important role in the extra digestive manifestations of IBD. It should be systematically screened in IBD patients, especially if they present a biological inflammatory syndrome, thus enabling early diagnosis and better management.

Abstract
Purpose: This study determines whether fluorescein angiography (FA) with a 250-mg dose of fluorescein (half dose) is equal in quality to the standard 500-mg dose of fluorescein (full dose) when using digital ultra-widefield (UWF) technology. Methods: In a randomized, prospective study using a UWF imaging system, FAs performed with half dose were compared with angiograms performed with full dose. Imaging studies were reviewed by 4 reviewers based on 6 characteristics: dye transit, macrovasculature, macula detail, microvasculature, leakage, and overall quality. The scores for macrovasculature, macula detail, microvasculature, and overall quality were converted to a fuzzy rating score to confirm results. Results: Seventy-nine FAs from 67 patients were reviewed for this study, including 12 patients who had both half-dose and full-dose FAs. Of all the factors studied, only microvasculature received a significantly different score between full dose and half dose that was confirmed by the fuzzy rating scale (3.79 vs 3.53; P = .04). Among those eyes that received both full and half dose, there was no significant difference in any of the 6 factors. Conclusions: In a UWF imaging system, aside from looking at fine microvascular abnormalities, the 250-mg dose of fluorescein provided similar results to a 500-mg dose. The images were not significantly different in overall quality.

Abstract
PURPOSE: Trochleitis has been recognized as one of the causes of eye pain and migraine headaches. This study attempts to investigate the effect of ibuprofen on reducing eye pain and migraine headaches caused by trochleitis. METHODS: In this before-after clinical trial, out of 1100 clinically examined patients with eye pain and migraine symptoms, 33 patients were diagnosed with having trochleitis and trochleodynia confirmed by orbital magnetic resonance imaging images. Ibuprofen (400 mg/6–8 h) was prescribed to the subjects for 15–30 days. The main outcomes were a reduction in tenderness and pain that were evaluated 2 weeks, a month, and 6 months after the prescription. The data were analyzed by STATA (version 14) and using Wilcoxon and McNemar tests. RESULTS: The results revealed that 28 of the subjects (84.8%) experienced a significant reduction in tenderness 2 weeks after undergoing the treatment (P < 0.001). Standard deviation and average of headache scores before and after the treatment were 7.85 ± 1.75 and 0.64 ± 0.61 based on the visual analog scale. The difference between the pain scores before and after the treatment was statistically significant (P < 0.001). Clinical symptoms such as induration (P < 0.001), photophobia (P < 0.001), upward gaze (P < 0.001), and pain after reading (P < 0.001) were reduced significantly. Six months after the treatment, none of the mentioned symptoms was reported by the subjects. CONCLUSION: The findings revealed that noninvasive treatment (ibuprofen) has reduced eye pain, tenderness, and migraine headaches caused by trochleitis. What is important to mention is that trochleitis should be diagnosed properly.

Abstract
PURPOSE To compare three-year surgical outcomes of trabeculectomy versus Ahmed valves in patients with prior failed trabeculectomy. METHODS This is a longitudinal retrospective comparative study of one-hundred twenty adult patients with prior failed trabeculectomy who underwent a repeat trabeculectomy or Ahmed valve implant. Demographic and clinical data were collected up to 3 years on all study participants at the Kresge Eye Institute from 2004 to 2016. Visual acuity, intraocular pressure, number of intraocular pressure reducing medications, and success rates at various time points up to 3 years after repeat surgery were the main outcome variables. RESULTS Sixty-five and sixty eyes were included in the trabeculectomy and the Ahmed valve groups, respectively. Baseline intraocular pressure significantly decreased in both groups at 3 years (p < 0.01). The number of medications was relatively similar to baseline in both study groups at 3 years (p > 0.05). There was no statistically significant difference between the two groups in visual acuity, percentage of intraocular pressure reduction, number of medications, or success rates at any follow-up time points (p > 0.05 for all). CONCLUSIONS AND RELEVANCE After 3 years, both trabeculectomy and Ahmed valves significantly reduced intraocular pressure from baseline, but with relatively similar number of medications compared to baseline. There was no significant difference in any outcome measure between trabeculectomy and Ahmed valves at any follow-up time points. These results may suggest neither trabeculectomy or Ahmed valves are superior in patients with previously failed trabeculectomies.

Abstract
The aim of the present systematic review is to evaluate the impact of gender reassignment surgery on the development of urethral complication. A systematic search in accordance the Preferred Reporting Items for Systematic Review and Meta-Analyses statement for original articles published up until June 2019 was performed using the Pubmed, Scopus, Embase, and Web of Science databases. Pooled analyses were done when appropriate. The bibliographic search with the included terms (("Transsexualism"[Mesh])) AND ("Sex Reassignment Surgery"[Mesh]) produced a literature of 879 articles altogether. After removing papers of not interest or articles in which the outcomes could not be deduced, 32 studies were examined for a total of 3463 patients screened. Thirty-two studies met our inclusion criteria and were evaluated, and references were manually reviewed in order to include additional relevant studies in this review. Female-to-male (FtM) surgery and male-to-female (MtF) surgery was discussed in 23 and 10 studies, respectively. One study discussed both. Varying patterns of complications were observed in FtM and MtF surgeries, with increased complications in the former because of the larger size of the neourethra. Meatal stenosis is a particular concern in MtF surgery, with complication rates ranging from 4 to 40%, and usually require meatotomy for repair. Stricture and fistulization are frequently reported complications following FtM surgery. In studies reporting on fistulae involving the urethra, 19-54% of fistulae resolved spontaneously without further surgical intervention. High rates of complications are reported in the current literature, which should be understood by patients and practitioners alike. Shared decision making with patients regarding incidence and management of urethral complications including stricture disease and fistulae, particularly after FtM surgery, is critical for setting expectations and managing postoperative outcomes.

Abstract
PURPOSE To investigate the frequency of conjunctival erosions in a series of patients who underwent Ahmed valve implantation in a tertiary referral center and to study risk factors associated with the conjunctival erosions. METHODS This is a single-center, retrospective case-control study of all patients who underwent Ahmed valve implantation between October 2006 and July 2016 at the Kresge Eye Institute in Detroit, Michigan. The series consisted of 306 eyes (277 patients) that underwent Ahmed valve implantation. The rate of conjunctival erosions was determined. Univariate, bivariate, and Cox-proportional hazard analyses were performed to identify factors associated with conjunctival erosions. RESULTS During the study period, 23 erosions occurred in 306 eyes (7.52%). Aphakia was significantly more common in eyes with erosions (P < 0.05). Aphakia (P = 0.02), uveitic glaucoma (P = 0.03), and longer post-operative use of topical steroids (P < 0.04) significantly increased the risk of erosions based on the Cox model. There were similar rates of erosions with each type of patch graft. No conjunctival erosion was observed after using the modified scleral tunnel method (n = 10). CONCLUSIONS The overall erosion rate was 7.52% in our series. Uveitic glaucoma, aphakia, and longer post-operative use of topical steroids were significantly associated with conjunctival erosions.

Abstract
PURPOSE The purpose of this study was to evaluate the visual acuity as well as endothelial cell density (ECD) and polymegathism after iris-fixated lens (Artiflex® AC 401) implantation for correction of moderate to high myopia. PATIENTS AND METHODS In this retrospective cross-sectional study, 55 eyes from 29 patients undergoing iris-fixated lens implantation for correction of myopia (-5.00 to -15.00 D) from 2007 to 2014 were evaluated. Uncorrected visual acuity, best spectacle-corrected visual acuity, refraction, ECD and polymegathism (coefficient of variation [CV] in the sizes of endothelial cells) were measured preoperatively and 6 months postoperatively. RESULTS In the sixth month of follow-up, the uncorrected vision acuity was 20/25 or better in 81.5% of the eyes. The best-corrected visual acuity was 20/30 or better in 96.3% of the eyes, and more than 92% of the eyes had a refraction score of ±1 D from the target refraction. The mean corneal ECD of patients before surgery was 2,803±339 cells/mm2, which changed to 2,744±369 cells/mm2 six months after surgery (p=0.142). CV in the sizes of endothelial cells before the surgery was 25.7%±7.1% and six months after surgery it was 25.9%±5.4% (p=0.857). CONCLUSION Artiflex iris-fixated lens implantation is a suitable and predictable method for correction of moderate to high myopia. There was no statistically significant change in ECD and polymegathism (CV in the sizes of endothelial cells) after 6 months of follow-up.

Abstract
Introduction: Neurotrophic keratitis is a rare degenerative corneal disease caused by an impairment of trigeminal corneal innervation, leading to a decrease or absence of corneal sensation. Here, we present a case of neurotrophic keratopathy caused by B12 deficiency in a 34 years old man who had a progressive decrease in visual acuity and corneal involvement since 3 months before being referred to our ophthalmology clinic. Result and Discussion: Based on our clinical findings and with the diagnosis of B12 deficiency we started B12 treatment for the patient. After 3 weeks the patient showed a dramatic response with corneal sensation reversal, an increase of visual acuity, improved neurotrophic keratopathy and significantly improved neurological findings. To the best of our knowledge, there is no report regarding vitamin B12 deficiency induced keratopathy and this is the first report that describes this aspect of vitamin B12 deficiency.

Abstract
Purpose To report on the efficacy and safety of combined phacoemulsification and an Ahmed valve glaucoma drainage implant with respect to visual acuity improvement, intraocular pressure (IOP) control, and requirement for antiglaucoma medication. Methods A retrospective chart review was conducted of 41 eyes (31 patients) with coexisting visually significant cataracts and uncontrolled glaucoma who had combined phacoemulsification and Ahmed valve implantation. The outcome measures were: visual acuity, IOP, antiglaucoma medication requirements, and intra- and post-operative complications. Success was categorized as absolute (IOPp<21 mmHg without the need for antiglaucoma medication) and relative (IOPp<21 mmHg with one or more antiglaucoma medications). Failure was considered to be an IOPp<6 mmHg or IOP>21 mmHg on maximally tolerated medications or any devastating complication. Results The mean patient age was 67.3±5.9 years old. The mean visual acuity improved from 0.73±0.5 to 0.16±0.16 (p=0.000). The mean IOP decreased from 28.2±3.1 to 16.8±2.1 (p=0.000, 40.4%), while the number of antiglaucoma medication decreased from 2.6±0.66 to 1.2±1.4 (p=0.000). The absolute and relative success rates were 56.1% and 31.7%, respectively; 5 eyes (12.2%) were considered failures. There were no intraoperative complications; postoperative complications occurred in 8 eyes (19.5%). A hypertensive phase was detected in 12 (29.3%) eyes. Conclusions Combined phacoemulsification and Ahmed valve glaucoma drainage implantation is a safe and effective alternative to phacotrabeculectomy in patients with coexisting cataract and refractory glaucoma.

Abstract
Concerns regarding the potential for broken chains and "reneges" within kidney paired donation (KPD) and its effect on chain length have been raised previously. Although these concerns have been tested in simulation studies, real-world data have yet to be evaluated. The purpose of this study was to evaluate the actual rate and causes of broken chains within a large KPD program. All patients undergoing renal transplantation through the National Kidney Registry from 2008 through May 2016 were included for analysis. Broken chains and loops were identified. A total of 344 chains and 78 loops were completed during the study period, yielding a total of 1748 transplants. Twenty broken chains and one broken loop were identified. The mean chain length (number of transplants) within broken chains was 4.8 compared with 4.6 of completed chains (p = 0.78). The most common causes of a broken chain were donor medical issues incurred while acting as a bridge donor (n = 8), donors electing not to proceed (n = 6), and kidneys being declined by the recipient surgeon (n = 4). All recipients involved in a broken chain subsequently received a transplant. Based on the results, broken chains are infrequent, are rarely due to lack of donor motivation, and have no significant impact on chain length.

Abstract
PURPOSE To determine the causes of lacrimal gland inflammation based on histopathology and systemic evaluation. METHODS This is a retrospective case series study. From the University of British Columbia Orbit Clinic between January 1976 and December 2008, we reviewed the medical records of 60 patients who presented with inflammatory features of the lacrimal gland (i.e., erythema, edema, or tenderness) in which the diagnoses were not possible clinically and on imaging alone. As was our routine practice, all these patients underwent lacrimal gland biopsy before starting any treatment. RESULTS The histopathologic findings of the 60 patients showed that 37 (61.7%) had identifiable types of lacrimal inflammation including 10 with Sjogren's syndrome, seven with sarcoidal reaction, six with feature of granulomatosis with polyangiitis (formerly known as Wegener's granulomatosis), five with lymphoma, two with sclerosing inflammation, two with IgG4-related dacryoadenitis, and one patient each with infectious dacryoadenitis, myoepithelial carcinoma, xanthogranuloma, eosinophilic angiocentric fibrosis, and eosinophilic allergic granulomatous nodule. The histopathologic findings of the remaining 23 (38.3%) patients showed nonspecific inflammation of the lacrimal gland. 23 patients (38.3%) had associated systemic diseases. 48 patients (80%) were treated successfully and 10 (16.7%) had recurrence of inflammation. CONCLUSIONS We recommend that in patients presenting with lacrimal gland inflammation (i.e., erythema, edema, tenderness) in which the specific diagnosis cannot be made clinically and on imaging, biopsy is warranted for accurate diagnosis and appropriate treatment. We found that the majority of these patients (61.7%) had specific histopathology, and 38% had systemic diseases.

Abstract
PURPOSE To analyze the impact of the Medicare Access and CHIP Reauthorization Act of 2015 (MACRA) on the field of ophthalmology. DESIGN A perspective on the effects of MACRA's Quality Payment Program after analysis of the proposed rule, final rule, and commentary submitted by relevant stakeholders. RESULTS Physicians will need to use 1 of 2 payment structures: Merit-Based Incentive Payment Systems (MIPS) or Alternative Payment Models (APMs). APMs and MIPS will focus on bundling payments and reimbursing based on "fee-for-service-plus" models, which take into account clinical outcomes, coordination of care, clinical improvement, and electronic information exchange and security. APMs have substantial advantages, with eligible participants receiving a bonus and a higher rate of annual adjustment over the program's life. For most ophthalmology practices, MIPS may be more appropriate owing to its broader applicability and the current paucity of APMs for ophthalmologists. CONCLUSION The Quality Payment Program is a substantial improvement over the negative adjustments under the repealed Substantial Growth Rate model. Ophthalmologists will likely use the MIPS system; however, its comparatively lower reimbursements, as well as its cost, quality, and other reporting measures, may prove problematic.

Abstract
BACKGROUND The Global Burden of Diseases, Injuries, and Risk Factors Study 2015 provides an up-to-date synthesis of the evidence for risk factor exposure and the attributable burden of disease. By providing national and subnational assessments spanning the past 25 years, this study can inform debates on the importance of addressing risks in context. METHODS We used the comparative risk assessment framework developed for previous iterations of the Global Burden of Disease Study to estimate attributable deaths, disability-adjusted life-years (DALYs), and trends in exposure by age group, sex, year, and geography for 79 behavioural, environmental and occupational, and metabolic risks or clusters of risks from 1990 to 2015. This study included 388 risk-outcome pairs that met World Cancer Research Fund-defined criteria for convincing or probable evidence. We extracted relative risk and exposure estimates from randomised controlled trials, cohorts, pooled cohorts, household surveys, census data, satellite data, and other sources. We used statistical models to pool data, adjust for bias, and incorporate covariates. We developed a metric that allows comparisons of exposure across risk factors-the summary exposure value. Using the counterfactual scenario of theoretical minimum risk level, we estimated the portion of deaths and DALYs that could be attributed to a given risk. We decomposed trends in attributable burden into contributions from population growth, population age structure, risk exposure, and risk-deleted cause-specific DALY rates. We characterised risk exposure in relation to a Socio-demographic Index (SDI). FINDINGS Between 1990 and 2015, global exposure to unsafe sanitation, household air pollution, childhood underweight, childhood stunting, and smoking each decreased by more than 25%. Global exposure for several occupational risks, high body-mass index (BMI), and drug use increased by more than 25% over the same period. All risks jointly evaluated in 2015 accounted for 57·8% (95% CI 56·6-58·8) of global deaths and 41·2% (39·8-42·8) of DALYs. In 2015, the ten largest contributors to global DALYs among Level 3 risks were high systolic blood pressure (211·8 million [192·7 million to 231·1 million] global DALYs), smoking (148·6 million [134·2 million to 163·1 million]), high fasting plasma glucose (143·1 million [125·1 million to 163·5 million]), high BMI (120·1 million [83·8 million to 158·4 million]), childhood undernutrition (113·3 million [103·9 million to 123·4 million]), ambient particulate matter (103·1 million [90·8 million to 115·1 million]), high total cholesterol (88·7 million [74·6 million to 105·7 million]), household air pollution (85·6 million [66·7 million to 106·1 million]), alcohol use (85·0 million [77·2 million to 93·0 million]), and diets high in sodium (83·0 million [49·3 million to 127·5 million]). From 1990 to 2015, attributable DALYs declined for micronutrient deficiencies, childhood undernutrition, unsafe sanitation and water, and household air pollution; reductions in risk-deleted DALY rates rather than reductions in exposure drove these declines. Rising exposure contributed to notable increases in attributable DALYs from high BMI, high fasting plasma glucose, occupational carcinogens, and drug use. Environmental risks and childhood undernutrition declined steadily with SDI; low physical activity, high BMI, and high fasting plasma glucose increased with SDI. In 119 countries, metabolic risks, such as high BMI and fasting plasma glucose, contributed the most attributable DALYs in 2015. Regionally, smoking still ranked among the leading five risk factors for attributable DALYs in 109 countries; childhood underweight and unsafe sex remained primary drivers of early death and disability in much of sub-Saharan Africa. INTERPRETATION Declines in some key environmental risks have contributed to declines in critical infectious diseases. Some risks appear to be invariant to SDI. Increasing risks, including high BMI, high fasting plasma glucose, drug use, and some occupational exposures, contribute to rising burden from some conditions, but also provide opportunities for intervention. Some highly preventable risks, such as smoking, remain major causes of attributable DALYs, even as exposure is declining. Public policy makers need to pay attention to the risks that are increasingly major contributors to global burden. FUNDING Bill & Melinda Gates Foundation.

Abstract
PURPOSE To study angular and temporal vein engorgement following periorbital hyaluronic acid gel (HAG) injection. METHODS In this retrospective study, the authors reviewed the photographs of 805 patients who had periorbital HAG injection at Jules Stein Eye Institute Oculoplastic Clinic between January 2004 and January 2014. HAG injections were used to fill the orbital hollow, zygomatic hollow, septal confluence hollow, and cheek. The inclusion criteria were patients who had at least 1 pre-, immediate post-, and late postinjection photographs. Immediate postinjection photographs were taken right after HAG injection, and late postinjection photographs were taken at the following visit before any injection. The exclusion criteria were patients with any previous ocular surgery 6 months before filler injection, patients with orbital diseases, and patients who had HAG injections for functional purposes. The photographs were evaluated for the presence of angular and temporal vein engorgement at any of the injections during the follow-up visits. The photographs of eyes with vein engorgement were graded on a scale of 0 (no engorgement), 1 (mild engorgement), 2 (moderate engorgement), and 3 (severe engorgement). RESULTS There were 78 eligible patients (156 orbits; 68 females and 10 males) with average age of 59.4 ± 13.4 years. The authors found 18 orbits of 12 patients (15.4%; 6 unilateral and 6 bilateral) with angular vein engorgement at least 1 time after HAG injection during the follow-up visits. The frequency of temporal vein engorgement was 9.1%. The mean ± SD of angular vein grading for engorgement increased from 0.72 ± 0.51 on preinjection photographs to 1.45 ± 0.88 on immediate postinjection photographs (p = 0.0001) and 0.89 ± 0.50 on late postinjection photographs (p = 0.04). The mean ± SD of angular vein grading for engorgement was 0.67 ± 0.55 on the first preinjection photographs, which increased to 1.10 ± 0.50 on the last late postinjection photographs. The difference was statistically significant (p = 0.001). CONCLUSIONS Angular and temporal vein engorgement occurred following HAG injection in the periorbital region. The engorgement occurred immediately after injections and decreased considerably but not completely in the following visit.

Abstract
AIM To investigate the effects of periocular injection of propranolol and celecoxib on ocular levels of vascular endothelial growth factor (VEGF) in a diabetic mouse model. METHODS Forty 4-6wk BALB-C male mice weighing 20-25 g were used. The study groups included: non-diabetic control (group 1), diabetic control (group 2), diabetic propranolol (group 3), and diabetic celecoxib (group 4). After induction of type 1 diabetes by streptozotocin, propranolol (10 µg) and celecoxib (200 µg dissolved in carboxymethylcellulose 0.5%) were injected periocularly. The ocular level of VEGF was measured in all the study groups using enzyme-linked immuno sorbent assay (ELISA) method. RESULTS Ocular VEGF level was significantly increased (1.25 fold) in the diabetic control group when compared to the non-diabetic group one week after induction with streptozotocin (P=0.002). Both periocular propranolol and celecoxib significantly reduced ocular VEGF levels (P=0.047 and P<0.001, respectively). The effect was more pronounced with celecoxib. CONCLUSION The periocular administration of propranolol and celecoxib can significantly reduce ocular VEGF levels in a diabetic mouse model.

Abstract
AIM To compare the efficacy of single-session 360-degree selective laser trabeculoplasty (SLT) for reduction of intraocular pressure (IOP) in patients with pseudoexfoliative glaucoma (PXFG) and primary open angle glaucoma (POAG). METHODS This is a single-center, prospective, nonrandomized comparative study. Patients older than 18 years of age with uncontrolled PXFG or POAG eyes requiring additional therapy while on maximally tolerated IOP-lowering medications were included. The primary outcome measure changed in IOP from baseline. Success was defined as IOP reduction ≥20% from baseline without any additional IOP-lowering medication. All patients were examined at 1d, 1wk, 1, 3, 6, 9, 12mo after SLT. RESULTS Nineteen patients (20 eyes) with PXFG and 27 patients (28 eyes) with POAG were included in the study. In the visual fields mean deviation was -2.88 (±1.67) in the POAG and -3.1 (±1.69) in the PXFG groups (P=0.3). The mean (±SD) IOP was 22.9 (±3.7) mm Hg in the POAG group and 25.7 (±4.4) mm Hg in the PXFG group at baseline and decreased to 18.4 (±3.2) and 18.0 (±3.9) mm Hg in the POAG group (P<0.001 and P=0.02), and to 17.9 (±4.0) and 21.0 (±6.6) mm Hg in the PXFG group (P<0.001 and P=0.47) at 6 and 12mo, respectively. The number of medications was 2.6 (±0.8) in the POAG group and 2.5 (±0.8) in the PXFG group at baseline, and did not change at all follow-up visits in both groups (P=0.16 in POAG and 0.57 in PXFG). Based on Kaplan-Meier survival analysis, the success rate was 75% in the POAG group compared to 94.1% in the PXFG group (P=0.08; log rank test) at 6mo, and 29.1% and 25.0% at 12mo, respectively (P=0.9; log rank). CONCLUSION The 360-degree SLT is an effective and well-tolerated therapeutic modality in patients with POAG and PXFG by reducing IOP without any change in number of medications. The response was more pronounced early in the postoperative period in patients with PXFG whereas there was no statistically significant difference at 12-month follow-up.

Abstract
PURPOSE To compare refractive outcomes, contrast sensitivity, higher-order aberrations (HOAs), and patient satisfaction after photorefractive keratectomy for correction of moderate myopia with two methods: tissue saving versus wavefront optimized. METHODS In this prospective, comparative study, 152 eyes (80 patients) with moderate myopia with and without astigmatism were randomly divided into two groups: the tissue-saving group (Technolas 217z Zyoptix laser; Bausch & Lomb, Rochester, NY) (76 eyes of 39 patients) or the wavefront-optimized group (WaveLight Allegretto Wave Eye-Q laser; Alcon Laboratories, Inc., Fort Worth, TX) (76 eyes of 41 patients). Preoperative and 3-month postoperative refractive outcomes, contrast sensitivity, HOAs, and patient satisfaction were compared between the two groups. RESULTS The mean spherical equivalent was -4.50 ± 1.02 diopters. No statistically significant differences were detected between the groups in terms of uncorrected and corrected distance visual acuity and spherical equivalent preoperatively and 3 months postoperatively. No statistically significant differences were seen in the amount of preoperative to postoperative contrast sensitivity changes between the two groups in photopic and mesopic conditions. HOAs and Q factor increased in both groups postoperatively (P = .001), with the tissue-saving method causing more increases in HOAs (P = .007) and Q factor (P = .039). Patient satisfaction was comparable between both groups. CONCLUSIONS Both platforms were effective in correcting moderate myopia with or without astigmatism. No difference in refractive outcome, contrast sensitivity changes, and patient satisfaction between the groups was observed. Postoperatively, the tissue-saving method caused a higher increase in HOAs and Q factor compared to the wavefront-optimized method, which could be due to larger optical zone sizes in the tissue-saving group.

Abstract
PURPOSE To describe the association of lacrimal gland inflammation with alopecia areata. METHODS We reviewed the medical records of 4 patients diagnosed with lacrimal gland inflammation who had an antecedent or subsequent episode of alopecia. Data was collected on the presentation age, gender, medical history, disease onset, symptoms and signs, imaging, histopathology, systemic evaluation, management and outcome. Pathology and imaging results were correlated with clinical findings. RESULTS Three patients were Asian and one Caucasian. Two developed alopecia after presentation for lacrimal inflammation. The remaining two had a history of alopecia totalis (2 years and 10 years). Three of the 4 patients presented or developed other systemic disorders, including seizures, thrombocytopenia, optic neuritis, ulcerative colitis, allergic rhinitis, lymphadenopathy, vasculitic rash and positive p-ANCA values. All received oral corticosteroids, with the addition of methotrexate therapy in one for relapsing inflammation. CONCLUSIONS Lacrimal gland inflammation and alopecia areata are autoimmune processes that can be seen in association with each other.

Abstract
We evaluated the effect of AAV2- and 17-AAG (17-N -allylamino-17-demethoxygeldanamycin)-mediated upregulation of Hsp70 expression on the survival of retinal ganglion cells (RGCs) injured by optic nerve crush (ONC). AAV2-Hsp70 expression in the retina was primarily observed in the ganglion cell layer. Approximately 75% of all transfected cells were RGCs. RGC survival in AAV2-Hsp70 injected animals was increased by an average of 110% 2 weeks after the axonal injury compared to the control. The increase in cell numbers was not even across the retinas with a maximum effect of approximately 306% observed in the inferior quadrant. 17-AAG-mediated expression of Hsp70 has been associated with cell protection in various models of neurodegenerative diseases. We show here that a single intravitreal injection of 17-AAG (0.2 ug/ul) results in an increased survival of ONC injured RGCs by approximately 49% compared to the vehicle-treated animals. Expression of Hsp70 in retinas of 17-AAG-treated animals was upregulated approximately by 2-fold compared to control animals. Our data support the idea that the upregulation of Hsp70 has a beneficial effect on the survival of injured RGCs, and the induction of this protein could be viewed as a potential neuroprotective strategy for optic neuropathies.

Abstract
PURPOSE To review indications and clinical outcomes in a series of orbitocranial tumors treated surgically through a transorbital extradural approach without craniotomy. METHODS In this retrospective case series, all patients who underwent surgery through a transorbital extradural approach without craniotomy for benign orbitocranial tumors involving the dura or extending into the anterior or middle cranial fossae were analyzed. RESULTS Twenty-seven patients (20 females and 7 males) were included. Median age was 47.0 years (range: 6-74 years) and median follow-up time was 43.5 months (range: 3-148 months). The median preoperative best-corrected visual acuity (logMAR) was improved from 0.35 (range: 0-2.6) to 0.1 (range: 0-2.6) at the last follow-up (p < 0.03). The mean ± SD preoperative exophthalmos significantly decreased from 20.4 ± 3.4 mm to 13.1 ± 3.5 mm at the last follow-up visit (p < 0.01). Four postoperative complications were noted and included one case each of ptosis, numbness, diplopia (transient for 6 months), and cranial nerve VI palsy (transient for 4 months). CONCLUSIONS The transorbital extradural approach provides access to the deep orbit and adjacent extradural cranial spaces. Benign orbital tumors that have eroded through the orbital roof, are located in the orbital apex abutting the anterior cavernous sinus and tumors requiring debulking are all processes that can be potentially approached through the transorbital extradural route. Compared to open craniotomy, the incision is smaller, the access more direct and specific risks of open craniotomy are reduced.

Abstract
Purpose: To investigate the effect of cataract surgery and yellow-tinted intraocular lens (IOLs) implantation on perimetry indices of short-wavelength automated perimetry (SWAP) and standard automated perimetry (SAP) testing in patients with coexisting cataract and glaucoma. Materials and Methods: In this prospective comparative case series, phacoemulsification with implantation of yellow-tinted Acrysof Natural IOL was performed in 16 eyes of 16 patients with visually significant cataract (best-corrected visual acuity (VA) better than 20/120) and mild to moderate glaucoma. Pre- and postoperative values for VA and for perimetry indices including mean deviation (MD), pattern standard deviation (PSD), and foveal threshold (FT) from both SAP and SWAP testing were compared. Results: Postoperative VA improved significantly after cataract surgery and yellow-tinted IOL implantation (P < 0.001). After cataract extraction and IOL implantation, MD and FT on SWAP testing improved significantly (P = 0.001); however, there was no statistically significant change with SAP testing between the pre- and postoperative perimetry indices. There was no statistically significant change in PSD with either SAP or SWAP testing postoperatively. The differences between pre- and postoperative values for all perimetry indices under study were not significant when comparing SAP with SWAP tests, except for MD which had improved statistically significantly in SWAP testing (P = 0.03). Conclusions: In mild to moderate glaucoma patients with cataracts, the perimetry indices of SWAP testing improved after phacoemulsification and yellow-tinted IOL implantation. This suggests that the yellow-tinted IOLs have less effect on SWAP testing than visually significant cataracts.

Abstract
PURPOSE To determine inter-device agreement for central corneal thickness (CCT) measurement among ultrasound pachymetry, rotating Scheimpflug imaging (Pentacam, Oculus, Wetzlar, Germany), and scanning slit corneal topography (Orbscan II, Bausch & Lomb, Rochester, NY, USA) in highly myopic eyes before and after photorefractive keratectomy (PRK). METHODS This prospective comparative study included 61 eyes of 32 patients with high myopia who underwent PRK. Six month postoperative CCT values were compared to preoperative values in 27 patients (51 eyes) who completed the follow up period. To determine the level of agreement, Pentacam and Orbscan II readings were compared to ultrasonic pachymetry measurements as the gold standard method. RESULTS Mean CCT measurements with ultrasound, Pentacam, and Orbscan II before PRK were 557µm, 556µm, and 564µm, respectively; and 451µm, 447µm, and 438µm 6 months after surgery in the same order. Preoperatively, the 95% limits of agreement (LoA) with ultrasound measurements were -20μm to 17μm for Pentacam and -21μm to 33μm for Orbscan II. Six months postoperatively, the 95% LoA were -30μm to 23μm for Pentacam and -69μm to 43μm for Orbscan II. CONCLUSION Preoperatively, CCT measurements were higher with Orbscan II as compared to ultrasound. Postoperatively, both Pentacam and Orbscan II measurements were lower than those obtained with ultrasound, but Pentacam had better agreement. The use of ultrasound, as the gold standard method, or Pentacam both appear to be preferable over Orbscan II among patients with high myopia.

Abstract
PURPOSE To evaluate the performance of ganglion cell layer/inner plexiform layer (GCL/IPL) measurements with spectral-domain optical coherence tomography (Cirrus HD-OCT) for detection of early glaucoma and to compare results to retinal nerve fiber layer (RNFL) measurements. DESIGN Cross-sectional prospective diagnostic study. METHODS We enrolled 99 subjects, including 59 eyes with glaucoma (47 subjects) (mean deviation >-6.0 dB) and 91 normal eyes (52 subjects). Patients underwent biometry and peripapillary and macular OCT imaging. Performance of the GCL/IPL and RNFL algorithms was evaluated with area under receiver operating characteristic curves (AUC), likelihood ratios, and sensitivities/specificities adjusting for covariates. Combination of best parameters was explored. RESULTS Average (SD) mean deviation in the glaucoma group was -2.5 (1.9) dB. On multivariate analyses, age (P < 0.001) and axial length (P = 0.03) predicted GC/IPL measurements in normal subjects. No significant correlation was found between average or regional GC/IPL thickness and respective outer retina (OR) thickness measurements (P > 0.05). Average RNFL thickness performed better than average GCL/IPL measurements for detection of glaucoma (AUC = 0.964 vs 0.937; P = 0.04). The best regional measures from each algorithm (inferior quadrant RNFL vs minimum GCL/IPL) had comparable performances (P = 0.78). Entering the GC/IPL to OR ratio into prediction models did not enhance the performance of the GCL/IPL measures. Combining the best parameters from each algorithm improved detection of glaucoma (P = 0.04). CONCLUSIONS Regional GCL/IPL measures derived from Cirrus HD-OCT performed as well as regional RNFL outcomes for detection of early glaucoma. Using the GC/IPL to OR ratio did not enhance the performance of GCL/IPL parameters. Combining the best measures from the 2 algorithms improved detection of glaucoma.

Abstract
PURPOSE To report a novel method for measuring the vertical tilt angle of the optic nerve (ON) head and to investigate the associated factors. DESIGN Cross-sectional diagnostic study. METHODS One hundred and twelve normal, glaucomatous, and glaucoma suspect eyes (99 patients) were enrolled in this study. Subjects underwent a full eye examination, biometry, and spectral-domain optical coherence tomography (SDOCT). The vertical tilt angle was measured on high-resolution cross-sectional SDOCT images passing through the ON head and foveal centers using the inner edges of the Bruch membrane opening as the reference plane. The correlation between the vertical tilt angle with the ovality index and the potential associated factors was estimated with univariate and multivariate linear regression analyses. RESULTS The median (interquartile range, [IQR]) axial length and visual field mean deviation were 24.5 (23.8-25.3) mm and -0.9 (-2.76 to 0.26) dB. The median (IQR) tilt angle was 3.5 (1.2-11.2) degrees. There was a moderate correlation between the ovality index and tilt angle (Spearman ρ = 0.351; P < .001). In univariate analyses, axial length, spherical equivalent, and mean deviation were correlated with the tilt angle (P = .002, P = .011, and P = .013, respectively). Axial length, mean deviation, and their interaction showed a statistically significant correlation with the tilt angle in multivariate analyses (P = .044 for axial length, P = .039 for mean deviation, and P = .028 for their interaction). CONCLUSIONS We describe a new method for measuring the ON head vertical tilt angle with high-resolution SDOCT imaging. The ovality index demonstrated only a moderate correlation with the tilt angle measurements and hence is not a good proxy measure for the vertical ON head tilt angle. Axial length and visual field mean deviation are the main factors associated with the ON head vertical tilt angle. The underlying basis for the relationship of vertical tilt angle and glaucoma severity should be further explored.

Abstract
Graft versus host disease (GVHD) is a common complication of allogeneic stem cell transplantation (allo-SCT). Ocular GVHD develops in approximately 40-60% of patients following allo-SCT and its most common clinical manifestations include keratoconjunctivitis sicca and cicatricial conjunctivitis. Ocular GVHD may lead to severe ocular surface disease, which can significantly diminish quality of life and restrict daily activities. It is thus important to monitor the condition closely since with timely diagnosis, irreversible damage can be avoided. The current review will focus on updated information regarding ocular GVHD.

Abstract
Purpose: To compare the intraocular pressures (IOP) and ocular pulse amplitudes (OPAs) in patients with primary open-angle glaucoma (POAG) and pseudoexfoliation glaucoma (PXG), and to evaluate ocular and systemic factors associated with the OPA. Materials and Methods: In this prospective study, on 28 POAG and 30 PXG patients, IOP was measured with the Goldmann applanation tonometry (GAT) and the Pascal dynamic contour tonometry (DCT). Other measurements included central corneal thickness (CCT), vertical cup-to-disc ratio (CDR), and systolic and diastolic blood pressure. Statistical significance was defined as P < 0.05. Results: In each of the POAG and PXG groups, GAT IOP was correlated with CCT (r = 0.40, P = 0.03 and r = 0.35, P = 0.05, respectively), whereas DCT IOP and CCT were not correlated. In all patients and in the POAG group, OPA was positively correlated with DCT IOP (r = 0.39, P = 0.002). OPA was not correlated with CCT in the POAG (P = 0.80), nor in the PXG (P = 0.20) group, after adjusting for DCT IOP. When corrected for DCT IOP and CCT, there was a significant negative correlation between OPA and vertical CDR in all patients (r = −0.41, P = 0.002). There was no significant difference in OPA between groups (P = 0.55), even when OPA was adjusted for IOP and systolic and diastolic pressure (P = 0.40), in a linear regression model. Conclusion: DCT IOP and OPA are not correlated with CCT. There is no significant difference between the OPA of PXG and POAG eyes. OPA is correlated with DCT IOP, and is lower in eyes with more advanced glaucomatous cupping.

Abstract
AIMS To evaluate primary trabeculectomy with adjunctive mitomycin-C (MMC) in diabetic patients with primary open angle glaucoma (POAG). METHODS Patients with diabetes mellitus (DM) without retinopathy who had ≥6 months of postoperative follow-up were retrospectively compared with a control group selected from the pool of patients without DM matched case-by-case to the diabetic group by age, gender, race, preoperative intraocular pressure (IOP) and lens status. Surgical success was defined as IOP ≤15 and >5 mm Hg (± glaucoma medications) without complications or additional glaucoma surgery. RESULTS 41 eyes (29 patients) with DM and 81 eyes (64 patients) without DM were compared. Kaplan-Meier cumulative survival rates at 60 months were 57.8±9.3% (DM group) and 68.6±5.3% (control group), and the mean trabeculectomy survival times were 63 months (DM group, 95% CI 50.3 to 75.7) and 74.6 months (control group, 95% CI 67.1 to 82.1; p=0.095). Mean postoperative IOP of control group was statistically significant lower at 2-, 3-, 6- and 7-year follow-up visits (p<0.05). Rates of postoperative complications and additional glaucoma surgeries required were not different between the two groups. CONCLUSIONS POAG patients with DM without retinopathy undergoing primary trabeculectomy with MMC do not achieve the same long-term IOP control and may have a lower long-term surgical survival rate compared with patients without DM.

Abstract
PURPOSE To evaluate the effect of cataract surgery on intraocular pressure (IOP) in filtered eyes with primary angle closure glaucoma (PACG). METHODS In this prospective interventional case series, 37 previously filtered eyes from 37 PACG patients with mean age of 62.1±10.4 years were consecutively enrolled. All patients had visually significant cataracts and phacoemulsification was performed at least 12 months after trabeculectomy. Visual acuity, IOP and the number of glaucoma medications were recorded preoperatively, and 1, 3, 6 and 12 months after surgery. Anterior chamber (AC) depth was measured preoperatively and 3 months after cataract surgery with A-scan ultrasonography. The main outcome measure was IOP at 12 months. RESULTS IOP was decreased significantly from 18.16±5.91 mmHg at baseline to 15.37±2.90 mmHg at final follow-up (P<0.01). The mean number of glaucoma medications was significantly decreased from 1.81±0.24 to 0.86±1.00 (P=0.001) at 1 year postoperatively. At final follow up, 36 (97.2%) eyes and 32 (86.4%) eyes had IOP≤21 and IOP≤18 mmHg, respectively; 14 (37.8%) eyes and 9 (24.3%) eyes had IOP≤21 and IOP≤18 mmHg without medications, respectively. The magnitude of IOP reduction was correlated with higher preoperative IOP (r=0.85, P<0.001), shallower preoperative AC depth (r=-0.38, P=0.01) and greater changes in AC depth (r=-0.39, P=0.01). CONCLUSION Cataract surgery reduces IOP and the number of glaucoma medications in previously filtered PACG eyes. This reduction seems to be greater in patients with higher preoperative IOP and shallower anterior chambers.

Abstract
OBJECTIVE To explore longitudinal correlations between structural and functional rates of glaucoma progression with confocal scanning laser ophthalmoscopy and standard achromatic perimetry. METHODS In this retrospective longitudinal study, 108 eyes with suspected or established glaucoma and 5 or more good-quality scanning laser ophthalmoscopy examinations (global pixel SD<50 μm) and 6 or more reliable visual field (VF) examinations were included. Global and regional rates of progression for VF sensitivity and rim area (RA) were calculated with linear regression analysis. Correlations of global and regional rates of progression were calculated with bivariate correlation analyses. Linear mixed models were built to determine predictive factors for functional and structural changes over time. RESULTS The mean (SD) baseline mean deviation was -4.6 (4.9) decibels. The inferotemporal and superotemporal RAs had the highest overall rates of decay (0.0018 mm2/y). Glaucoma progressed in 38 (35.2%) and 20 (18.5%) eyes based on event and trend mean deviation criteria, respectively. The highest correlations of rates were observed between the superonasal or superotemporal RA and inferior VF clusters (ρ=0.25-0.39; P≤.03). Follow-up time, baseline RA, and their interaction were the only significant predictors for RA change; belonging to the group with progression was not associated with higher rates of RA progression. CONCLUSIONS Longitudinal structure-function relationships are fair at best in eyes with suspected or established glaucoma. Eyes with progressing disease according to VF criteria do not show significantly higher rates of RA progression. Both structural and functional outcomes need to be monitored to detect glaucoma progression in a timely manner.

Abstract
BACKGROUND AND OBJECTIVE Conjunctival limbal autograft is the surgical treatment of choice for visually significant unilateral limbal stem cell deficiency. The use of fibrin glue, which has been reported extensively in pterygium and other conjunctival surgeries, has not been fully described in limbal stem cell transplantation. PATIENTS AND METHODS The authors reviewed 3 cases of conjunctival limbal autograft and 1 of living related conjunctival limbal allograft using only fibrin glue to secure the graft. Main outcome measures included ocular surface stability, visual acuity, and postoperative complications. RESULTS At most recent follow-up, all 4 patients (100%) maintained a stable ocular surface. Mean epithelial healing time was 10 days. Mean visual acuity improved from 20/400 to 20/53. All grafts were successful with no postoperative dislocations or displacements. CONCLUSION The findings demonstrate that fibrin glue can be used safely and effectively to secure conjunctival limbal grafts in limbal stem cell deficiency. This novel approach has the potential to decrease operative time, increase ease of technique, and improve patient comfort postoperatively.

Abstract
OBJECTIVE To investigate the prevalence of glaucoma, visual field abnormalities, as well as changes in retinal nerve fiber layer in patients with obstructive sleep apnea syndrome (OSAS). METHODS In this cross-sectional study, 51 patients with OSAS were included. Based on apnea hypopnea index (AHI), there were 26, 6 and 19 cases of severe (AHI⩾30), moderate (15⩽AHI<30), and mild (5⩽AHI<15) OSAS, respectively. The control group was matched for age, sex and body mass index. Prevalence of glaucoma and ocular hypertension as well as the following values were assessed and compared between two groups: best-corrected visual acuity, intraocular pressure, central corneal thickness (CCT), cup:disk ratio, mean deviation (MD), pattern standard deviation, and retinal nerve fiber layer (RNFL) parameters using glaucoma diagnosis measurement (GDx). RESULTS Seven eyes (6.7%) had intraocular pressure (IOP)>21mmHg; of these, four eyes (3.9%) had glaucoma. No significant difference was detected in CCT between the two groups. IOP was significantly higher in the OSAS group before (p<0.001) and after (p<0.001) correcting for CCT. There was a significant difference between groups in MD and most GDx parameters including DISK (temporal-superior-nasal-inferior-temporal) average (p=0.002), superior average (p=0.05) and nerve fiber indicator (NFI) (p=0.03), where those in the patient group showed lower values. There was a significant positive correlation between AHI and both IOP and NFI. CONCLUSIONS OSAS patients had a higher prevalence of glaucoma and ocular hypertension. OSAS patients also had higher IOP, worse visual field indices, and lower RNFL parameters compared with the control group.

Abstract
PURPOSE To compare the aqueous concentration of erythropoietin (EPO) in eyes with primary open-angle (POAG), pseudoexfoliative (PXFG), and neovascular (NVG) glaucoma with age-matched eyes with cataracts, and to correlate its concentration with other factors including age, gender, intraocular pressure (IOP), type of glaucoma, and severity of glaucoma. METHODS In this prospective non-randomized comparative study, a total of 26 eyes with cataracts (control group) and 92 glaucomatous eyes (POAG, 40 eyes; PXFG, 26 eyes; NVG, 26 eyes) were enrolled. Aqueous samples (0.1 to 0.2 ml) were obtained during phacoemulsification, trabeculectomy, phacotrabeculectomy, or Ahmed valve glaucoma implants. The aqueous concentration of EPO was measured using an enzyme-linked immunosorbent assay. RESULTS The mean±SEM aqueous level of EPO was statistically significantly higher in eyes with glaucoma (56.7±9.3 mIU/ml) compared to the control group (0.8±0.51 mIU/ml; p<0.001). Eyes with NVG had the highest aqueous level of EPO. Aqueous EPO concentrations remained considerably elevated even in eyes with controlled IOP in all three types of glaucoma. Eyes with PXFG displayed the greatest change in aqueous EPO concentration proportionate to the IOP level. In simple regression analysis, IOP, mean deviation, and the type of glaucoma were the factors that had a statistically significantly positive correlation with the aqueous level of EPO (p=0.011 and <0.001, respectively). Only the type of glaucoma remained statistically significant in the multiple regression analysis (adjusted R(2)=0.278). CONCLUSIONS Compared to the control group, the aqueous humor EPO concentration is increased in eyes with POAG, PXFG, and NVG, both with and without controlled IOP. The aqueous level of EPO was more proportionate to the level of IOP in eyes with PXFG compared to eyes with POAG and NVG.

Abstract
PURPOSE To compare visual outcomes and contrast sensitivity after wavefront-optimized or conventional photorefractive keratectomy (PRK) in myopic patients with or without astigmatism. SETTING Vanak Eye Surgery Center, Tehran, Iran. DESIGN Comparative case series. METHODS Patients with low to moderate myopia with or without astigmatism were allocated into 2 groups. The study group was treated with wavefront-optimized PRK (Allegretto Wave Eye-Q software version 2.020 default treatment) and the control group, with conventional PRK (Technolas 217z). In all cases, treatments were bilateral and performed with the same device. Baseline and 3-month postoperative measures were uncorrected and corrected distance visual acuities, manifest refraction, and contrast sensitivity. RESULTS Each group comprised 66 eyes. The mean preoperative spherical equivalent refraction improved from -2.99 diopters (D) ± 1.02 (SD) preoperatively to -0.08 ± 0.26 D 3 months postoperatively in the study group and from -2.66 ± 0.95 D to 0.01 ± 0.30 D, respectively, in the control group. In both groups, the postoperative mesopic and photopic contrast sensitivity decreased significantly at most spatial frequencies. The postoperative decrease in contrast sensitivity in both groups was comparable except at spatial frequencies of 3 cycles per degree (cpd) under mesopic conditions and 12 cpd under photopic conditions, frequencies at which the control group had a greater reduction. CONCLUSIONS Visual acuity and refractive error outcomes were similar in both treatment groups. After 3 months, mesopic and photopic contrast sensitivity were significantly decreased in both groups; the reduction in the 2 groups was almost comparable.
