Quality of and access to green space in relation to psychological distress: results from a population-based cross-sectional study as part of the EURO-URHIS 2 project.

Background: Psychological distress (PD) (mental ill-health) has a frequency between 5 and 25% in urban populations, and there is mounting evidence that access to green space might reduce its occurrence. Evidence suggests that the quality of green space is as important as accessibility in promoting mental well-being. A pilot study for EURO-URHIS 2 allowed investigation of access to green space in relation to PD in a deprived urban population in the UK. Methods: An adult urban health indicator questionnaire, including the GHQ-12 and validated questions on access to and quality of green space, was sent to a stratified random sample of 1680 adults drawn from one general practice list in Sandwell, UK. Multivariable logistic regression was used to determine associations between attributes of green space and PD adjusting for age, sex and levels of deprivation. Results: There were 578 (35%) completed responses. The reported prevalence of PD [n = 131 (22.7%)] was significantly greater than national England and Wales estimates. As well as accessibility (OR = 0.58; 95% CI = 0.35, 0.96) and sufficiency (OR = 0.12; 95% CI = 0.39, 0.89) of green spaces, having the ability to use them for relaxation and recreation were significantly associated with reduced PD [OR = 0.13 (0.42, 0.94) and OR = 0.11 (0.34, 0.80), respectively]. In addition, a dose-response relationship between number of positive green space attributes and PD was identified (P < 0.05). Conclusion: This population-based study in a deprived urban UK population demonstrates an association, and some dose-response relationship, between access to and quality of green spaces with reduced PD. The cross-sectional design and use of subjective measures limit interpretation of causality. More knowledge is needed on how UK planning affects green spaces and the potential mental health consequences.

Health status in Europe: comparison of 24 urban areas to the corresponding 10 countries (EURO-URHIS 2).

Background: : In Europe, over 70% of the population live in urban areas (UAs). Most international comparative health research is done using national level data, as reliable and comparable urban data are often unavailable or difficult to access. This study aims to investigate whether population health is different in UAs compared with their corresponding countries. : Routinely available health-related data were collected by the EURO-URHIS 2 project, for 10 European countries and for 24 UAs within those countries. National and UA level data for 11 health indicators were compared through the calculation of relative difference, and geographical patterns within Europe were investigated using the Mann Whitney U test. Linear regression modelling was used to adjust for population density, gross domestic product and urbanicity. : In general, the urban population in Eastern Europe is less healthy than the Western European urban population. However, people in Eastern Europe have significantly better broad health outcomes in UAs as compared with the corresponding country as a whole, whereas people in Western Europe have generally worse broader health outcomes in UAs. : For most European countries and UAs that were investigated, the national level health status data does not correspond with the health status at UA level. In order to identify health problems in UAs and to provide information for local health policy, health monitoring and international benchmarking should also be conducted at the local level.

Characterization of a low pathogenic avian influenza H5N2 virus isolated from a turkey breeder flock in Manitoba, Canada.

In November 2010, an outbreak of avian influenza (AI) due to the H5N2 subtype virus occurred in a turkey breeder farm in northern Manitoba, Canada. The only clinical signs observed were depression, decrease in food consumption, and loss of egg production. The hemagglutinin (HA) cleavage (HA(0)) site of the isolated H5N2 virus was PQRETR/GLF, consistent with low pathogenic AI viruses. The intravenous pathogenicity index of this virus was zero. Whole-genome sequencing of two isolates that originated from two different barns was performed, and both isolates had 100% identical protein sequence in PB2, HA, NP, M1, M2, NS1, and NS2. The remaining gene segments (PB1, PA, and NA) had a single amino-acid difference when compared with each other. The nucleotide and protein sequences of eight gene segments from both isolates showed 99 or greater identity with other AI viruses that have been circulating in free-living aquatic birds in Canada and the United States within the last 10 yr. Phylogenetic analysis of the HA and neuraminidase (NA) gene segments showed that these viruses are closely related to other H5 strains that have been isolated from Manitoba and other parts of Canada. Serologic testing of archived serum samples collected from these turkeys a week before the outbreak showed no evidence of AI infection. In addition, other farms that were located within 3 km radius from the infected farm and farms that had epidemiologic connection with the farm also tested negative for the presence of H5N2 AI virus or antibody. This indicates that the virus might have been introduced to the farm from wild aquatic birds only a short time before detection. Results of this study highlight the importance of early detection and the significance of ongoing Canada-wide surveillance of AI in domestic poultry as well as in wild aquatic birds/ducks.

Can foods with added soya-protein or fish-oil reduce risk factors for coronary disease? A factorial randomised controlled trial.

BACKGROUND AND AIMS: To develop functional foods which are capable of reducing key risk factors for coronary heart disease in an at risk population. The specific hypothesis tested here was that providing bread, cracker biscuits and snack bars fortified with DHA (long-chain omega 3) and soya-protein would havd a positive impact on cholesterol and blood pressure. METHODS AND RESULTS: A pragmatic, double-blind, factorial placebo-controlled randomised trial recruiting 213 middle-aged men and women with untreated elevated total cholesterol or blood pressure. The factors examined were the effect of giving supplies of bread, cereal bars and cracker biscuits fortified with 2 g fish oils (DHA, 22: 6n-3), or 25 g soya-protein (containing 50 mg of isoflavonoids) for five weeks. Primary and secondary outcomes included total, low-density and high-density cholesterol (HDL-C), and systolic and diastolic blood pressure. Compliance was assessed using biomarkers and food intake histories. DHA enriched foods increased HDL-C by 6.0% (95% CI 2.5%, 9.6%) but had no effect on total or low-density cholesterol or blood pressure. Overall, soya-protein did not influence any of the outcomes assessed. However, in women only, soya-protein increased systolic blood pressure by 5.9% (95% CI 1.73, 9.9%). CONCLUSIONS: Adding DHA (fish-oils) to staple foods might supplement existing methods to help reduce CVD morbidity and mortality. However, these findings highlight the importance of ensuring that functional foods do not present any harms to particular subgroups within a general population, if they are to be made freely available to consumers. This latter point requires further attention by the research community in relation to soya-protein.

The public health function in central and eastern Europe.

This paper provides a description of the structure and function of public health within seven central and eastern European countries. The information was gathered from senior figures within public health in these countries, who came together at a European Union (EU)-funded seminar on public health which aimed to share recent developments in the public health function in their countries, and to develop a shared vision of the future for public health across an (eventually) much enlarged and united EU. An essential starting point for this was a clear understanding of how public health operates within each of the countries involved. The information gathered and presented here suggests that the countries of central and eastern Europe included in this survey have much in common with current EU member states, in that public health is held to be of national importance. On the whole, they share similar priorities. The organization of the public health function varies quite considerably and variations of degrees of central and local control are manifested. There is also variation in the relationship between the 'health' and 'environmental' aspects of public health. In some countries, these are distinctly separate areas of activity, whereas in others they are integrated. All countries acknowledge that public health practice is a multidisciplinary activity, but this is not necessarily backed up with unified systems for co-ordinated education, training and development, open to all. Continued cross-Europe discussion, exchange of information on the development of the public health function, and collaboration on training, education and development in public health will be of mutual benefit and is essential if high standards in public health practice are to be achieved and maintained across the whole of the European region.

Transscleral suture fixation of posterior chamber lenses combined with trabeculectomy.

OBJECTIVE: To evaluate the outcome of transscleral suture-fixated posterior chamber intraocular lens (PCIOL) implantation in glaucoma patients when combined with a trabeculectomy. DESIGN: A retrospective study of 56 consecutive glaucoma patients with a minimum follow-up of 6 months after transscleral suture-fixated PCIOL implantation combined with trabeculectomy. SETTING: Patients were drawn from the clinical glaucoma practice of the Kresge Eye Institute, Detroit, MICHIGAN: PATIENTS: Fifty-six eyes of 56 consecutive chronic glaucoma patients who had undergone transscleral suture-fixated PCIOL implantation in combination with a trabeculectomy were included in the analysis. RESULTS: The mean follow-up time was 38.5 +/- 19.1 months. Mean intraocular pressure (IOP) was significantly reduced, from 22.9 +/- 10.9 mmHg before surgery to 16.7 +/- 6.7 mmHg at the last follow-up visit (P = 0.0005), with the mean number of medications used also significantly decreased, from 2.3 +/- 0.9 to 1.9 +/- 0.9 (P = 0.0002). Postoperative IOP control to 21 mmHg or less was achieved or maintained in 84% of patients. Visual acuity improved or remained stable within two Snellen lines of the preoperative level in 39 eyes (70%) and within three Snellen lines in 45 eyes (80%) at the last follow-up visit. Overall, 46% to 68% of the patients had both stable visual acuity and satisfactory pressure control at the last postoperative visit, depending on criteria of varying stringency. However, 19 eyes (34%) required one or more additional surgical interventions for pressure control. Patients with anterior chamber intraocular lens (ACIOL) complications, diabetes mellitus, or a preoperative IOP level of more than 21 mmHg on maximum tolerated medications were especially prone to requiring additional surgical interventions. CONCLUSIONS: We conclude that transscleral suture-fixated PCIOL implantation can be combined successfully with a trabeculectomy and can be useful in glaucoma patients in need of both visual rehabilitation and IOP control. However, patients with ACIOL complications, diabetes, or preoperative IOP of more than 21 mmHg on maximum tolerated medications were prone to requiring additional surgical interventions.

Prospective evaluation of eyelid function with gold weight implant and lower eyelid shortening for facial paralysis.

OBJECTIVES: To assess which signs and symptoms were relieved by gold weight implantation and which signs and symptoms persisted. DESIGN: Prospective observational cohort. SETTING: Tertiary care neurotology and oncology center. PATIENTS: Sixteen (4 males and 12 females) consecutive patients whose average age was 56 years (age range, 31-76 years). Inclusion criteria were gold weight implant, lagophthalmos of 2 mm or more, and a House-Brackmann score of 3 or less at the completion of follow-up. Mean follow-up was 13 months. INTERVENTIONS: Each patient received a gold weight implant. Six of these patients underwent a lower eyelid procedure. MAIN OUTCOME MEASURES: Surgical complications, static and dynamic lagophthalmos, static and dynamic corneal coverage, visual acuity, keratitis, topical treatment, and patient satisfaction. RESULTS: There were no extrusions. The preoperative mean lagophthalmos was 7.5 mm and the postoperative mean was 0.5 mm, (P<.001). Corneal coverage with eye closure before implantation was 73% and after implantation was 100%, (P<.001). Corneal coverage with normal (reflex) blink was less than 50% in 9 of 14 patients. When wearing correction, no patients had 20/20 visual acuity. The mean patient satisfaction score before the procedure was 3.5 and after was 7.1, (P<.001). Patient satisfaction was most closely related to visual acuity. The relationship was linear and statistically significant (P<.04). CONCLUSIONS: Gold weight implantation provides significant reduction in lagophthalmos and significant improvement in corneal coverage. But owing to delayed closure time and disrupted tear film, irritation may persist. As a result, some patients require ongoing topical treatment of the eye, which can compromise visual acuity.

Probing peripheral and central cholinergic system responses.

OBJECTIVE: The pharmacological response to drugs that act on the cholinergic system of the iris has been used to predict deficits in central cholinergic functioning due to diseases such as Alzheimer's disease, yet correlations between central and peripheral responses have not been properly studied. This study assessed the effect of normal aging on (1) the tropicamide-induced increase in pupil diameter, and (2) the reversal of this effect with pilocarpine. Scopolamine was used as a positive control to detect age-dependent changes in central cholinergic functioning in the elderly. DESIGN: Randomized double-blind controlled trial. PARTICIPANTS: Ten healthy elderly (mean age 70) and 9 young (mean age 33) volunteers. INTERVENTIONS: Pupil diameter was monitored using a computerized infrared pupillometer over 4 hours. The study involved 4 sessions. In 1 session, tropicamide (20 microL, 0.01%) was administered to one eye and placebo to the other. In another session, tropicamide (20 microL, 0.01%) was administered to both eyes, followed 23 minutes later by the application of pilocarpine (20 microL, 0.1%) to one eye and placebo to the other. All eye drops were given in a randomized order. In 2 separate sessions, a single dose of scopolamine (0.5 mg, intravenously) or placebo was administered, and the effects on word recall were measured using the Buschke Selective Reminding Test over 2 hours. OUTCOME MEASURES: Pupil size at time points after administration of tropicamide and pilocarpine; scopolamine-induced impairment in word recall. RESULTS: There was no significant difference between elderly and young volunteers in pupillary response to tropicamide at any time point (p > 0.05). The elderly group had a significantly greater pilocarpine-induced net decrease in pupil size 85, 125, 165 and 215 minutes after administration, compared with the young group (p < 0.05). Compared with the young group, the elderly group had greater scopolamine-induced impairment in word recall 60, 90 and 120 minutes after administration (p < 0.05). CONCLUSION: There is an age-related pupillary response to pilocarpine that is not found with tropicamide. Thus, pilocarpine may be useful to assess variations in central cholinergic function in elderly patients.

Efficacy of apraclonidine 1% versus pilocarpine 4% for prophylaxis of intraocular pressure spike after argon laser trabeculoplasty.

OBJECTIVE: The authors compared the efficacy of apraclonidine 1% versus pilocarpine 4% prophylaxis of post-argon laser trabeculoplasty (ALT) intraocular pressure (IOP) spike. DESIGN: Prospective randomized clinical trial. PARTICIPANTS: Two hundred twenty-eight eyes of 228 patients with primary open-angle glaucoma undergoing ALT were studied. INTERVENTION: Patients were given 1 drop of either apraclonidine 1% (n = 114) or pilocarpine 4% (n = 114) 15 minutes before ALT. MAIN OUTCOME MEASURES: Peri-ALT IOPs and incidences of post-ALT IOP spikes at 5 minutes, 1 hour, and 24 hours were compared between the two groups. RESULTS: The two groups were similar in age, race, and medical dependency. Post-ALT mean IOPs at 5 minutes, 1 hour, and 24 hours were significantly lower than pre-ALT mean IOPs in both apraclonidine (P < 0.001) and pilocarpine (P < 0.001) groups. Incidences of IOP spikes greater than 1, 3, and 5 mmHg at 1 hour post-ALT were 21.1%, 14.9%, and 8.8% for the apraclonidine group and 12.3%, 5.3%, and 4.4% for the pilocarpine group (P = 0.076, 0.015, and 0.18 chi-square test). In the apraclonidine prophylaxis group, patients on long-term apraclonidine showed significantly higher incidence of post-ALT IOP spike than the patients without such long-term apraclonidine use (35.7%, 15 of 42 eyes, vs. 12.5%, 9 of 72 eyes; P = 0.003). In addition, peri-ALT pilocarpine prophylaxis tended to be less effective in patients undergoing long-term pilocarpine therapy but without statistical significance (17.4%, 8 of 46 eyes, vs. 9.4%, 6 of 64 eyes; P = 0.17). CONCLUSION: Peri-ALT pilocarpine 4% was at least as effective as, if not more effective than, apraclonidine 1% in post-ALT IOP spike prophylaxis. Peri-ALT apraclonidine prophylaxis was not effective in patients on long-term apraclonidine, and peri-ALT pilocarpine prophylaxis tended to be less effective in patients undergoing long-term pilocarpine therapy. Pilocarpine 4% can be considered as a first-choice drug for post-ALT IOP spike prophylaxis, especially in patients under treatment with apraclonidine.

Comparison between high-pass resolution perimetry and differential light sensitivity perimetry in patients with glaucoma.

PURPOSE: High-pass resolution perimeters such as the Ophthimus (High Tech Vision, Malmö, Sweden) may provide an easier, faster assessment of the visual field than conventional perimeters such as the Humphrey (Humphrey Instruments Inc., San Leandro, CA, U.S.A.), which is based on differential light sensitivity. The Ophthimus provides global indices and statistical analyses conceptually similar to those produced by the Humphrey. In addition, the Ophthimus provides, as a unique parameter, the estimated neural capacity. PATIENTS AND METHODS: Twenty-one patients with chronic open-angle glaucoma and reliable fields on both Humphrey and Ophthimus testing were evaluated. The results from the two different techniques were compared. RESULTS: The estimated neural capacity was correlated to global deviation and mean deviation at a statistically significant level. There were also correlations between mean deviation and global deviation and between pattern standard deviation and local deviation, but not between retest standard deviation and short-term fluctuation. CONCLUSION: It is not clear at this point if the neural capacity of the Ophthimus provides any clinically useful information over and above global deviation. Mean test time was shorter with the Ophthimus system than the Humphrey. Performance on the reliability indices was better for the Ophthimus. The Ophthimus may prove useful in following patients with glaucoma.

The effect of adjunctive mitomycin C in Molteno implant surgery.

PURPOSE: The purpose of the study is to assess the effect of adjunctive intraoperative mitomycin C (MMC) in Molteno drainage device implantation for patients with recalcitrant glaucomas. METHOD: Forty-nine eyes of 49 patients who underwent one-stage, single-plate Molteno device implantation with adjunctive intraoperative MMC (0.5 mg/ml) for 3 to 5 minutes (MMC group) were compared to a historic control group of 51 eyes of 51 patients (control group) who received one-stage, single-plate Molteno device implantation without MMC. Success (survival) was defined as an intraocular pressure (IOP) between 6 and 21 mmHg, inclusive, with (qualified success) or without (complete success) glaucoma medications and with no additional glaucoma surgery, phthisis, implant removal, or loss of light perception. RESULTS: Preoperative conditions were similar between the two groups. There was no significant difference in surgical survival rate between the two groups (P = 0.13, log-rank test). There also were no significant differences in the postoperative IOP levels and numbers of antiglaucoma medications between the two groups at all times (P > 0.05). Visual acuity was improved or remained within one line of preoperative visual acuity in 76.1% of the MMC group and 78.7% of the control group at 1 year after surgery (P = 0.76, chi-square test). Complications and reoperation for complications were similar in both groups (P > 0.05, chi-square test) except for the incidence of early postoperative hypotony and the total number of eyes with complications not requiring reoperation, which were more common in the MMC group (P = 0.027, 0.005, respectively, chi-square test). The most common complications included hypotony with or without a flat anterior chamber or choroidal detachment, followed by hyphema and tube plugging. CONCLUSION: Molteno device implantation with adjunctive intraoperative MMC in patients with complicated glaucoma may not offer a better chance of surgical success compared with Molteno implantation without MMC.

Chronic use of apraclonidine decreases its moderation of post-laser intraocular pressure spikes.

OBJECTIVE: The purpose of the study is to investigate the efficacy of 1.0% apraclonidine in preventing intraocular pressure (IOP) spike after argon laser trabeculoplasty (ALT) in patients on chronic apraclonidine therapy compared with patients not on chronic apraclonidine use. DESIGN: The study design was a prospective study. PARTICIPANTS: This study consisted of 231 consecutive eyes of patients with primary open-angle glaucoma undergoing ALT: 70 eyes (30%) were started on a regimen including chronic apraclonidine 0.5% use (group A) and 161 eyes (70%) were started on a regimen without chronic apraclonidine 0.5% use (group B). INTERVENTION: Both groups received one drop of apraclonidine 1.0% 15 minutes before ALT to 180 degrees of previously untreated trabecular meshwork. Intraocular pressure was measured before the procedure and at 5 minutes, 1 hour, and 24 hours after the laser treatment. MAIN OUTCOME MEASURES: Incidences of an IOP spike and mean IOPs at 5 minutes, 1 hour, and 24 hours after the laser treatment were compared between the two groups. Multivariate logistic regression analysis also was carried out to identify the significant risk factors for post-ALT IOP spikes despite prophylactic apraclonidine 1.0% treatment. RESULTS: The incidences of IOP spikes greater than 0 mmHg, greater than 2 mmHg, and greater than 5 mmHg at 1 hour after ALT were 32.9%, 22.9%, and 12.9%, respectively, in group A versus 13.7%, 11%, and 3.1%, respectively, in group B (P = 0.0007, P = 0.009, and P = 0.004). Chronic apraclonidine 0.5% use was found to be the only significant risk factor for IOP spikes at 1 hour after ALT by multivariate logistic regression analysis. CONCLUSIONS: The incidences of IOP spikes in group A were significantly greater than in group B and approached the reported incidences of IOP spikes without perilaser apraclonidine prophylaxis. This indicates that peri-ALT apraclonidine is relatively ineffective in patients with chronic apraclonidine 0.5% use (group A) compared with patients without chronic apraclonidine use (group B), presumably because of saturation of the ocular alpha-2 receptors with apraclonidine in patients with chronic apraclonidine use. Therefore, in patients receiving chronic apraclonidine therapy, it is especially important to monitor their post-ALT IOPs and to be prepared to treat postlaser IOP spikes using agents other than apraclonidine.

How should public health policy be developed? A case study in European public health.

BACKGROUND: Article 129 of the Treaty of Rome (as amended at Maastricht) gave new powers to the European Union (EU) institutions to develop and implement public health programmes at EU level. The authors were invited by the cabinet of Commissioner Flynn to assist the Commission by developing new policy proposals in certain specific areas. METHODS: The approach was agreed with officials of the Public Health Unit (now the Public Health and Safety Directorate) in DG V. Working groups of experts were appointed to review policy options in five discrete areas. The experts were resident in 13 of the 15 current EU member states, and were employed in academic departments, in health ministries, in local government, and in non-governmental organizations. Draft reports were presented to an evaluation panel of additional experts, whose comments contributed to the final report to the Commission. RESULTS: The final report consisted of five main chapters, corresponding to the work of the five working groups. The recommendations were grouped into those for which implementation would be short term, medium term or longer term, and these were summarized as a Plan of Action. CONCLUSION: Five criteria for good public health policy development were satisfied, but the approach used was excessively expensive and time-consuming. Some further lessons for future policy development work have also been recorded. This work provided a fascinating insight into the workings of the EU institutions.

Analysis of reliability indices from Humphrey visual field tests in an urban glaucoma population.

PURPOSE: Visual field assessment is extremely important in glaucoma management, but interpretation is affected by the quality of the patient's performance. The authors have investigated the reliability of visual field performance by a randomly selected sample of the chronic glaucoma population at an urban tertiary care practice. METHODS: Patient reliability in Humphrey automated visual field testing was studied in 106 randomly selected chronic open-angle glaucoma patient charts, which provided 768 tests (mean, 7.2 +/- 4.8 fields; range, 2-18 fields). Reliability criteria were established as less than 20% fixation losses, less than 33% false-negative error, and less than 33% false-positive error, as recommended by Humphrey Instruments, Inc (San Leandro, CA). RESULTS: Patients performed reliably in 61% of right eye fields, 58% of left eye fields, and 59.5% overall. Of the 106 patients, only 35 (33%) were always reliable in both eyes, whereas 8 (7.5%) were always unreliable in both eyes. The most common cause of unreliability was fixation loss (39%), whereas false-positive error (5%) and false-negative error (9%) were less frequent. A more severely depressed mean deviation correlated significantly with poorer performance on the three reliability indices, with false-negative error having the greatest correlation, followed by fixation loss and false-positive error. Corrected pattern standard deviation correlated closely only with false-negative error. Prolonged test time also correlated with all three reliability indices. Age was a significant factor for fixation loss but not for false-negative or false-positive error. CONCLUSIONS: The authors conclude that fewer than two thirds of the Humphrey visual fields were reliable with the authors' urban tertiary care population of patients with glaucoma. Relaxing the fixation loss criterion to less than 33% improved the rate of reliability to approximately 75%. The severity of glaucomatous visual field defects, test time, and age were identified as factors influencing the reliability of the Humphrey visual fields.

Anterior chamber maintenance during drainage of a suprachoroidal hemorrhage in two phakic eyes.

BACKGROUND AND OBJECTIVES: The authors describe a technique for hemorrhage drainage following glaucoma surgery that uses an anterior chamber maintainer to minimize risk to the anterior lens capsule. PATIENTS AND METHODS: Two patients had suprachoroidal hemorrhages following filtration surgery. Because their eyes were phakic, an anterior chamber maintainer, as opposed to a 23-gauge butterfly needle, was used for aqueous replacement during hemorrhage drainage. RESULTS: The maintainer provided a stable anterior chamber environment during both drainage procedures. No damage to anterior chamber structures occurred, and the postoperative course was unremarkable in both patients. CONCLUSIONS: The use of a sharp-tipped infusion cannula may be contraindicated for the phakic patient who has a suprachoroidal hemorrhage. The anterior chamber maintainer is a useful alternative instrument in such cases.

Use of fascia lata in revision of filtration surgery.

PURPOSE: To report on a successful use of fascia lata patch graft in revision of trabeculectomy for management of severe chronic discomfort associated with an exuberant conjunctival filtering bleb over a very nasal filtering site. METHODS: After dissecting a conjunctival flap over the area of the trabeculectomy at the nasal quadrant, fascia lata patch graft was sutured in place over the filtering site when primary suture closure was found ineffective. A new trabeculectomy was performed temporal and superior to the old site, and the conjunctival wound closed watertight. RESULTS: The fascia lata patch graft was effective in closing the filtration over the old trabeculectomy site at the nasal quadrant, and a new filtering bleb developed superiorly over the new trabeculectomy site, resulting in sustained IOP control. CONCLUSION: Fascia lata patch graft was effective in revision of trabeculectomy.
