RESUMEN

Background and Objectives: To compare the long-term toxicity of infracyanine green (IFCG) to brilliant blue G (BBG) in inverted internal limiting membrane flap surgery (I-ILMFS) for large, full-thickness macular holes (FTMHs). Materials and Methods: Prospective randomized study including 39 eyes with ≥ 400 µm idiopathic FTMH who underwent I-ILMFS with either IFCG or BBG. Postoperative 6- and 12-month corrected distance visual acuity (CDVA), closure rate, and swept-source optical coherence tomography parameters, including ellipsoid zone (EZ) and external limiting membrane (ELM) mean defect length, central foveal thicknesses (CFT), parafoveal macular thickness (MT), ganglion cells and inner plexiform layer (GCL++) thickness, and peripapillary nerve fiber layer (pRNFL) thickness, were compared. Results: Nineteen eyes were included in the IFCG group and 20 eyes in the BBG group. In all cases a FTMH closure was found. CDVA improved at 6 and 12 months in both groups (p < 0.0005); the increase at 12 months was greater in the BBG group (p = 0.036). EZ and ELM defects did not differ between groups at either follow-up time. CFT at 12 months was greater in the BBG group (p = 0.041). A 12-months compared to 6-months MT decrease was present in both groups (p < 0.01). The GCL++ superior inner sector was thicker in the BBG group at 12 months (p = 0.036), as were the superior outer sector (p = 0.039 and p = 0.027 at 6 and 12 months, respectively) and inferior outer sector (p = 0.011 and p = 0.009 at 6 and 12 months, respectively). Conclusion: In our study BBG in I-ILMFS exhibits better long-term CDVA and retinal thickness than does IFCG, suggesting a lesser toxicity from BBG. These findings support the use of BBG over IFCG in I-ILMFS.

RESUMEN

BACKGROUND: Clinical studies comparing trabeculectomy augmented with Ologen implant (OLO) versus trabeculectomy plus mitomycin-C (MMC) show contradictory results. To obtain long-term data, we report an extended 5-year follow-up trial evaluating the safety and efficacy of OLO as adjuvant compared to low-dosage MMC in trabeculectomy. METHODS: Forty glaucoma patients (40 eyes) assigned to trabeculectomy with MMC or Ologen. PRIMARY OUTCOME: target IOP at ≤21, ≤17 and ≤15 mmHg; complete and qualified success endpoint rates. SECONDARY OUTCOMES: visual acuity (VA), mean deviation (MD), bleb evaluation, according to Moorfields Bleb Grading System (MBGS); spectral domain OCT (SD-OCT) bleb examination; number of glaucoma medications; frequency of postoperative complications. RESULTS: The mean preoperative IOP was 26.7(±5.2) in MMC and 27.3(±6.0) in OLO eyes. Mean 60-month percentage reduction in IOP was significant in both groups [40.9 (±14.2) and 42.1(±13.3) P = 0.01], with an endpoint value of 15.2 (±3.2) and 15.8 (±2.3) mmHg in MMC and OLO, respectively. Complete success rates at ≤ 21 mmHg target IOP were 65% and 70%, at ≤17 mm Hg 60% and 55%, and at the ≤15 mm Hg target IOP 35% and 45% in MMC and OLO, respectively. The Kaplan-Meier curves did not differ both for complete and qualified success at any target IOP, with no significant endpoint intergroup difference at ≤ 15 mm Hg (log-rank P = 0.595).The intergroup MBGS scores differed due to reduced central and peripheral vascularity in MMC group (P = 0.027; P = 0.041). SD-OCT analysis denied differences in bleb height between MMC vs OLO (140.5 ± 20.3 µ vs 129.2 ± 19.3 µ respectively; P =0.079). Mean antiglaucoma medications were significantly reduced (P < 0.0005) from 2.5 (±0.3) to 1.2 (±0.4) in MMC and from 2.6 (±0.2) to 1.4 (±0.3) in OLO group, with no intergroup differences (P = 0.08). Six (30%) cystic thin avascular blebs without oozing were recorded in the MMC group and 2 (10%) in the OLO group, without intergroup difference (P = 0.235). CONCLUSIONS: Our extended follow-up results confirm that Ologen implant yields efficacy and long-term success rates quite similar to MMC, with at least equivalent safety.

RESUMEN

BACKGROUND: Ocular syphilis is often difficult to diagnose because of the wide variation in clinical features.HIV co-infection may further complicate the picture. CASE PRESENTATION: Herein the authors report an unusual primary syphilitic ocular lesion in a 45-year-old Italian HIV-infected bisexual man who presented with a unilateral eyelid lesion. Associated precocious signs and symptoms in the posterior segment of both eyes, bilateral chorioretinitis and uveitis, are described. Intravenous penicillin and steroid treatment produced a rapid improvement in clinical status and complete resolution. CONCLUSIONS: Careful questioning about sexual behavior is crucial for unmasking unusual features of ocular syphilis in HIV-infected subjects.

RESUMEN

PURPOSE: To compare new-generation multifocal intraocular lenses (IOLs) with monofocal IOLs. DESIGN: Randomized prospective clinical trial. PARTICIPANTS: Sixty-two consecutive patients with cataract, seen between January of 2005 and January of 2006 at the Department of Ophthalmology of Palermo University Hospital in Italy, were bilaterally implanted with monofocal (AR 40, Advanced Medical Optics [AMO], Santa Ana, CA; 15 patients), multifocal refractive (Array SA40N, AMO; 16 patients), multifocal refractive (ReZoom, AMO; 15 patients), or multifocal diffractive pupil-independent (Tecnis ZM900, AMO; 16 patients) IOLs. INTERVENTION: Bimanual phacoemulsification. MAIN OUTCOME MEASURES: Primary outcomes were far, near, and intermediate visual acuity of the 4 IOL-implanted groups. Secondary outcomes were defocusing curves, contrast sensitivity, patients' quality of life (7-item visual function questionnaire [VF-7], halos and glare presence, overall satisfaction), and spectacle independence. Snellen visual acuity was measured as uncorrected visual acuity (UCVA), best corrected visual acuity (BCVA), uncorrected near visual acuity (UCNVA), best distance corrected near visual acuity (BDCNVA), best corrected near visual acuity (BCNVA), uncorrected intermediate visual acuity (UCIVA), and best distance corrected intermediate visual acuity (BDCIVA). RESULTS: UCNVA was 20/50 in the monofocal IOL group, compared with 20/32 or better in the multifocal IOL groups (P<0.0005). The monofocal IOL group exhibited a lower BDCNVA than the multifocal IOL groups (P<0.0005). The diffractive multifocal IOL group performed better than either refractive group (P = 0.007). UCIVA was significantly different (P = 0.001) among the groups: monofocal (AR 40) 20/32; multifocal refractive (Array SA40N) 20/30; multifocal refractive (ReZoom) 20/25; and multifocal diffractive (Tecnis ZM900) 20/30. Defocusing curves with -3.00 diopter lens exhibited a better trend in the diffractive group. The refractive multifocal IOL groups exhibited lower contrast sensitivities at 3 cycles/degree (P = 0.038). The VF-7 mean score was significantly lower in the monofocal than the multifocal IOL groups (P = 0.002). Night halos were more common in the refractive groups (P<0.01). Spectacle independence was 20% in the monofocal IOL group, 43.7% and 53.3% in the refractive multifocal IOL groups, and 87.5% in the diffractive multifocal IOL group (P<0.05). CONCLUSIONS: Multifocal IOLs provide a greater depth of focus and higher patient satisfaction, and make intermediate and near visual tasks easier than do monofocal lenses. New-generation, diffractive, pupil-independent multifocal IOLs provide better near vision, equivalent intermediate vision, less unwanted photic phenomena, and greater spectacle independence than either monofocal or refractive multifocal IOLs.

RESUMEN

BACKGROUND: To determine the epidemiological characteristics and visual outcome of ocular trauma in southern Italy. METHODS: All cases of ocular trauma admitted to Department of Ophthalmology of Palermo University, Italy, from January 2001-December 2005 were retrospectively reviewed for open- or closed-globe injury (OGI or CGI). Data extracted included age, sex, residence, initial and final visual acuity (VA), cause and treatment of injury, hospitalization. The injuries were classified by Ocular Trauma Classification System (OTCS) and Birmingham Eye Trauma Terminology (BETT). We also referred to the Ocular Trauma Score (OTS) in evaluating the final visual outcome. RESULTS: Of the 298 eyes, there were 146 OGI and 152 CGI. Fifty eyes (16.8%) had an intraocular foreign body (IOFB). The annual incidence of eye injuries was 4.9 per 100,000. Most injuries occurred in men (84.6%, p < 0.0005), with an average age of 33.0 vs. 49.9 for women (p = 0.005). Cause of injury differed significantly by gender (p = 0.001) and urban vs. rural location (p = 0.009). The most frequent causes in men were outdoor activities related injuries (30.9%), work-related (25.4%), and sport-related (17.5%), and in women were home-related (52.2%) and outdoor activities related injuries (30.4%). In urban areas, road accidents were more frequent; in rural areas, work-related injuries were more frequent with a greater rate of IOFBs than in urban areas (p = 0.002). The incidence of OGI and CGI differed in work-related injuries (p < 0.0005), sport-related injuries (p < 0.0005), and assaults (p = 0.033). The final visual acuity was 20/40 (6/12) or better in 144 eyes (48.3%), 20/40-20/200 (6/12-6/60) in 90 eyes (30.2%), and <20/200 (6/60) or less in 46 eyes (15.5%). Eighteen eyes (6%) had a final acuity of no light perception. Of those eyes that presented with hand motion vision or better, 220 (86.6%) had a final vision of better than 20/200 (6/60). Initial visual acuity was found to be correlated with final visual acuity (Spearman's correlation coefficient = 0.658; p < 0.001). The likelihood of the final visual acuities in the OTS categories was correlated to that of the OTS study group in 12 of 14 cases (85.7%). CONCLUSION: This analysis provides insight into the epidemiology of patients hospitalized for ocular trauma. The findings indicate that ocular trauma is a significant cause of visual loss in this population.

RESUMEN

AIMS: To compare the long-term effects of low-dosage mitomycin C (MMC) in both deep sclerectomy (DSMMC) and trabeculectomy (TPMMC) on intraocular pressure (IOP). METHODS: Analysis of extended follow-up of data from a prospective clinical trial. Forty patients were originally randomised to undergo either DSMMC (19 eyes) or TPMMC (21 eyes). Follow-up was performed at postoperative day 1, weeks 1, 2 and 3, as well as months 1, 3, 6, 9, 12, 18, 24, 36 and 48. Two- to three-week data were not included in the statistical analysis. Postoperative complications, number of antiglaucoma medications and IOP were recorded at each visit. Complete (no medications) and qualified (with or without medications) successes were assessed at 2 target IOPs (< or =21 and < or =17 mm Hg) and evaluated by Kaplan-Meier curves. RESULTS: At 48 months, the mean IOP (+/- SD) was 17.6 +/- 3.4 and 17.8 +/- 3.6 mm Hg in the DSMMC and TPMMC eyes, respectively, a significant reduction from preoperative IOP in each group (p < 0.0005). Complete success was achieved at the < or =21 mm Hg target IOP in 10 (52.6%) and 14 (66.6%) eyes and qualified success in 15 (78.9%) and 18 (85.7%) eyes in the DSMMC and TPMMC groups, respectively. There were no differences in the Kaplan-Meier curves. Hypotony and shallow anterior chamber were significantly more frequent in the TPMMC group. CONCLUSIONS: Either procedure controlled IOP efficaciously at our endpoint. Low-dosage MMC can be considered a mild enhancement of deep sclerectomy IOP-lowering effect.

RESUMEN

Lutein is a carotenoid with reported anti-inflammatory properties. A large body of evidence shows that lutein has several beneficial effects, especially on eye health. In particular, lutein is known to improve or even prevent age-related macular disease which is the leading cause of blindness and vision impairment. Furthermore, many studies have reported that lutein may also have positive effects in different clinical conditions, thus ameliorating cognitive function, decreasing the risk of cancer, and improving measures of cardiovascular health. At present, the available data have been obtained from both observational studies investigating lutein intake with food, and a few intervention trials assessing the efficacy of lutein supplementation. In general, sustained lutein consumption, either through diet or supplementation, may contribute to reducing the burden of several chronic diseases. However, there are also conflicting data concerning lutein efficacy in inducing favorable effects on human health and there are no univocal data concerning the most appropriate dosage for daily lutein supplementation. Therefore, based on the most recent findings, this review will focus on lutein properties, dietary sources, usual intake, efficacy in human health, and toxicity.

RESUMEN

BACKGROUND: Cataract day surgery has rapidly gained worldwide acceptance, because the new surgical techniques and costs are generally lower than those involved in ordinary hospitalization. Cataract surgery serves as a proxy indicator of the trend towards day surgery hospitalization in Italy and, therefore, of regional variability in health-care delivery and cost. The aim of this study was to update the diffusion of cataract day surgery through various surgical ophthalmological centers in central and southern Italy during 2005. METHODS: A two-stage stratified cluster sampling method was used to draw a sample of Cataract Surgery Unit from Ophthalmic Units of central and southern Italy. A questionnaire was sent to 25 cataract surgery centers in nine health districts that represented the range of establishments (public, private, accredited or otherwise) in which cataract surgery is performed. Data were collected on numbers of procedures performed in 2005, hospital admission type, time from the onset of cataract day surgery, surgical procedure, and presence of other surgical centers. RESULTS: The response rate was 42% (10 surveys), resulting in at least one completed questionnaire for each of these 9 districts. There is a positive trend towards day surgery hospitalization in all surgical centers. The percentage of patients treated as outpatients during 2005 varied from 50-60% (Avellino, Naples, Campobasso), to 80-90% (Rome, Bari), up to 90-100% (Catania, Palermo, Siracusa and Trapani), with an increasing trend in all the centers studied. Few differences were found in surgical procedures, and these were statistically insignificant. CONCLUSION: Our results confirm a positive trend towards day surgery in place of hospital inpatient admission for cataract surgery. This trend is expected to close the existing regional gap in Italy. Increased efficiency is an overriding need for the National Health Service in order to improve the rationalization of resources.

RESUMEN

Day surgery has rapidly gained worldwide acceptance especially in the field of ophthalmology. In Italy, cataract surgery is the most frequently performed surgical procedure, even on account of the ageing of the population. This procedure represents a very sensitive indicator of trends in day surgery hospitalizations and of political-managerial situations in the different regional healthcare realities. The aim of this study was to evaluate the diffusion of cataract day surgery in ophthalmology centres/divisions in central and southern Italy in 2003. A questionnaire was used to collect information regarding the number of surgical procedures performed, types of hospital admissions, time since the introduction of cataract day surgery, perioperative norms, and presence of other operative surgical centres in the area.

RESUMEN

PURPOSE: To compare the efficacy of non-penetrating deep sclerectomy without implant with Crozafon-De Laage punch trabeculectomy, and to evaluate the effect of simultaneous temporal approach phacoemulsification on both techniques. SETTING: Department of Ophthalmology of the University of Palermo. DESIGN: Prospective randomized clinical trial. Patients and intervention procedures: Sixty-five patients (65 eyes) with primary open angle glaucoma (POAG) or pseudoexfoliative glaucoma (PEXG): 32 eyes underwent non-penetrating deep sclerectomy (NPDS), 17 as single procedure and 15 combined with phacoemulsification (phaco-NPDS), and 33 eyes underwent punch trabeculectomy (PT), 18 single and 15 with phaco (phaco-PT). The patients were randomly assigned to each procedure. No adjuvants, such as Nd: YAG laser goniopuncture, laser suturelysis, and antimetabolites were used. MAIN OUTCOME MEASURES: Postoperative complications, number of antiglaucoma medications, and IOP level were checked at each control. Complete success indicated the achievement of the target IOP without antiglaucoma medications, while qualified success indicated the same goal with or without medications. These categories were assessed at two target IOP levels, namely < or =21 mm Hg and < or =17 mm Hg in all four groups. RESULTS: The mean follow-up period was 22.5 +/- 2.5 months. The mean preoperative IOP was 30.2 mm Hg in NPDS eyes, 26.8 in phaco-NPDS eyes, 32.1 in PT eyes, and 27.0 in phaco-PT ones, without significant intergroup difference. At the end point the mean IOP was 17.7 +/- 0.8, 15.7 +/- 0.9, 14.2 +/- 1.1, and 13.8 +/- 1.1 mm Hg respectively with postoperative IOP significantly lower (P = 0.005) than preoperative IOP in all groups. No difference was observed among groups at any observation time when simple and combined surgery were compared. Significant difference at the end point was found between NPDS and PT (P = 0.030). As for complete and qualified success with a < or =21 and < or =17 mm Hg target IOP no significant differences were noticed in all groups. Among postoperative complications, hypotony was significantly more frequent in both PT groups when compared with the NPDS groups. The same was true, but relating only to the single procedures, for shallow anterior chamber and choroidal detachment. The Kaplan-Meier cumulative survival curves relating to the qualified success rate in the four surgical groups for a < or =21 mm Hg target IOP (log rank, P = 0.564) and for a < or =17 mm Hg target IOP (log rank, P = 0.591) showed no significant intergroup differences. When the < or =21 mm Hg target IOP was considered, a mild positive trend in combined procedures (both phaco-NPDS and phaco-PT) was found in comparison with simple procedures. At lower IOP target (ie, < or =17 mm Hg) a better trend was found in favor of simple or combined PT procedure. CONCLUSIONS: Both techniques, NPDS and PT, without enhancements (ie, implants or antimetabolites) control IOP efficaciously at our end point. Phacoemulsification combined with penetrating and non-penetrating procedures does not seem to interfere with final results. When a lower target IOP and probability of success over time are considered, PT, single or combined, exhibits a better trend. PT, therefore, could be more suitable for higher IOP levels or longer life expectancies.

RESUMEN

PURPOSE: To test the expanded polytetrafluoroethylene (ePTFE) as a new adjuvant in trabeculectomy. METHODS: Consecutive glaucoma surgical inpatients were observed at the Department of Ophthalmology of Palermo University. Sixty patients (60 eyes) were randomly assigned to undergo trabeculectomy (T), trabeculectomy with mitomycin-C (TMMC), with ePTFE (TG) or with mitomycin-C and ePTFE (TGMMC). Postoperative visits were scheduled at 24 hr, 7 days, 1, 3, 6, 12, 18 and 24 months. Complete success and qualified success were assessed at two target intraocular pressure (IOP) levels -< or =21 and < or =17 mmHg - by Kaplan-Meier curves. RESULTS: The postoperative IOP reduction was significant (P < 0.01) at the endpoint in all groups, with a mean IOP of 16.9 (+/-2.9), 16.2 (+/-2.7), 15.3 (+/-3.4) and 15.2 (+/-4.3) mmHg in T, TMMC, TG and TGMMC eyes, respectively. No intergroup difference was found at either IOP targets. The Kaplan-Meier curves relating to either the < or =21 mmHg or the < or =17 mmHg target IOP did not show significant intergroup differences for complete and qualified success rate. When ePTFE was used, a trend favouring the medium-term survival rate was noted. No adverse reaction to the ePTFE was present, and no membrane extrusion or conjuctival erosion were noted in any cases. Hypotony was significantly more frequent (P = 0.035) in groups without ePTFE. Moreover, the late MMC-related complications were more frequent when MMC was applied. CONCLUSION: Expanded polytetrafluoroethylene implant in trabeculectomy is well tolerated and could act as a filtration modulating device. Therefore, it is useful in reducing early hypotony-related complications and contributes to attaining medium-term IOP control that is comparable to the low-dosage MMC.

RESUMEN

PURPOSE: To compare IOP behavior after deep sclerectomy (DS) and trabeculectomy with the Crozafon-De Laage Punch (TP), using low-dosage intraoperative mitomycin C (MMC) in both techniques. METHODS: The study was a prospective randomized clinical trial. All patients met inclusion and exclusion criteria, and were scheduled for glaucoma surgery. Forty patients were randomized to undergo either a nonpenetrating DS with MMC (DSMMC) (19 eyes) or a TP with MMC (TPMMC) (21 eyes). Postoperative examinations were performed at the 1st day, the 1st, 2nd and 3rd weeks and the 1st, 3rd, 6th, 9th and 12th months. Postoperative complications, number of antiglaucoma medications and the IOP level were checked at each control. Complete success (without antiglaucoma medications) and qualified success (with or without medications) were assessed at two target IOP levels, namely < or = 21 and < or = 17 mm Hg in both groups. Moreover, the success rates at < or = 21 mm Hg target IOP level were compared with those from previous series of patients who had undergone DS without MMC (historical control group). RESULTS: Data from all eyes were available until the 12th month. The mean preoperative IOP +/- SD was 29.6 +/- 5.8 mm Hg in DSMMC eyes, 28.0 +/- 6.0 in TPMMC eyes; the mean IOP at the 1st postoperative day was 12.5 +/- 4.2 and 13.9 +/- 6.5 mm Hg, while at the endpoint the mean IOP was 14.5 +/- 4.0 and 16.1 +/- 3.8, respectively, with significant reduction (p < 0.0005) of the preoperative IOP in both groups. Complete success (< or = 21 mm Hg target IOP) in 15 eyes (78.9%) of the DSMMC group and in 15 eyes (71.4%) of the TPMMC group was respectively found, while qualified success was achieved in all the eyes. When a < or = 17 mm Hg target IOP was considered, complete success in 12 eyes (63.1%) and 13 eyes (61.9%), and qualified success in 13 eyes (68.4%) and 15 eyes (71.4%) were found in the DSMMC and TPMMC groups, respectively. No significant intergroup differences were found in terms of success rate. There is no statistical significance in the Kaplan-Meier cumulative survival curves as for complete and qualified success rate in both surgical groups for a < or = 17 mm Hg target IOP (log rank, p = 0.918 and p = 0.429, respectively). As for the frequency of postoperative complications, hypotony and shallow anterior chamber were significantly more frequent in TPMMC when compared with the DSMMC group. The historical comparison between the DSMMC group and simple DS cases shows no significant difference between the groups, with a mild positive trend in DSMMC when compared with DS eyes. CONCLUSIONS: Both techniques, DSMMC and TPMMC, control IOP efficaciously at our endpoint. Our results indicate that low-dosage MMC can be considered a mild enhancement of DS IOP lowering effect without any negative effect on the well-known intra- and postoperative safety of the technique.
