RESUMO
PURPOSE: To analyze intraocular pressure (IOP) response after 20-mg decanted intravitreal triamcinolone acetonide followed by early prophylactic IOP-lowering therapy. METHODS: Overall, IOP results of 120 high-dose decanted intravitreal triamcinolone acetonide injections from 58 nonglaucomatous patients with macular edema, with antiglaucoma therapy prescribed from Week 1 regardless of baseline IOP were retrospectively reviewed. RESULTS: In cases of consistent compliance with IOP-lowering drugs (79.2%), IOP increased by 2 mmHg at 4 months (P = 0.300) and returned to baseline at 6 months. In cases of noncompliance (20.8%), IOP increased by 7 mmHg at 1 month (P < 0.001) and returned to baseline after starting treatment. Multivariate regression analysis showed that nonvitrectomized eyes and noncompliance with IOP-lowering drugs were independent predictors of increase in IOP greater than 21 mmHg (P = 0.0098 and P = 0.0019, respectively). Nonvitrectomized eyes had a 46% greater chance to experience increase in IOP compared with vitrectomized ones. Poor compliance with IOP-lowering drugs lead to a 45% greater likelihood of experiencing increase in IOP compared with compliant patients. Multiple injections were not associated with the increased risk for increase in IOP greater than 21 mmHg (P = 0.273). Of 120 cases, 2 eyes (1.7%) developed uncontrolled IOP and required glaucoma surgery by 4 months, with good final IOP outcome. CONCLUSION: Twenty milligram decanted intravitreal triamcinolone acetonide can be safely used to treat macular edema in nonglaucomatous patients; IOP elevation can be adequately controlled with prophylactic antiglaucoma drugs. Noncompliance with prophylactic therapy creates an early spike in IOP, and vitreous status can significantly impact increase in IOP. Compliance with IOP-lowering drugs should be stressed to patients receiving high-dose intravitreal triamcinolone acetonide especially in cases of nonvitrectomized eyes.

PURPOSE: To describe the vitreoretinal interface of the asymptomatic fellow eyes of patients with acute unilateral posterior vitreous detachment (PVD) based on biomicroscopic examination and spectral domain optical coherence tomography. METHODS: Sixty-five eyes of 65 consecutive patients with acute unilateral PVD were examined by slit-lamp, indirect ophthalmoscopy, and spectral domain optical coherence tomography. The state of PVD in different retinal locations and premacular pocket were assessed and graded using spectral domain optical coherence tomography. RESULTS: Nine eyes (13.85%) had no PVD, 15 (23.08%) had extrafoveal vitreous separation (Stage 1), 18 (27.69%) had partial foveal vitreous separation (Stage 2), 12 (18.46%) had complete foveal vitreous separation (Stage 3), and 11 (16.92%) had a complete PVD (Stage 4). The presence of a premacular pocket showed equal distribution in Stages 0, 1, and 2 (66.67, 80.00, and 77.78%, respectively) but was significantly less common in Stages 3 (P = 0.016) and 4 (P < 0.0001). Only certain posterior vitreous configurations were identified (P < 0.0001), suggesting an orderly progression of PVD evolution. CONCLUSION: Our spectral domain optical coherence tomography-based PVD staging system describes the evolution of PVDs. This can be used as a guide in predicting the occurrence and evolution of PVD in this population.

OBJECTIVE: To evaluate and compare the cumulative incidence and risk factors for first-episode immunologic graft rejection in Descemet's stripping automated endothelial keratoplasty (DSAEK) and penetrating keratoplasty (PK) and to identify potential risk factors for rejection. DESIGN: Retrospective chart review. PARTICIPANTS: All patients who underwent PK or DSAEK for endothelial disease at the Department of Ophthalmology, North Shore LIJ, between January 2004 and June 2010. METHODS: One hundred sixty-nine PK cases and 122 DSAEK cases were reviewed. All patients had a minimum of 3 months of follow-up, with median follow-up of 36 months in the PK group and 29 months in the DSAEK group. MAIN OUTCOME MEASURES: Cumulative incidence of first-episode immunologic graft rejection in PK and DSAEK cohorts. Risk factors for graft rejection were reviewed. RESULTS: Cumulative incidence of rejection was not significantly different between the DSAEK and PK cohorts (P<0.1324). However, among patients without glaucoma, the risk of rejection in PK was higher than that in DSAEK (hazard ratio [HR], 5.56). Prior incisional glaucoma surgery imparted a 3.15 times greater risk of rejection regardless of transplant type. Phakic patients were more likely to experience rejection than patients with a posterior chamber intraocular lens (HR, 3.23; P<0.0266), but not more likely than those with an anterior chamber intraocular lens or who were aphakic. Graft failure occurred within 6 months in 31% of PK rejections and none of the DSAEK rejections. CONCLUSIONS: Descemet's stripping automated endothelial keratoplasty and PK did not show a statistically significant difference in the incidence of rejection; however, among nonglaucomatous eyes, there were significantly fewer rejections in those that underwent DSAEK.

PURPOSE: To evaluate the possible benefit of pars plana vitrectomy in the treatment of patients with endophthalmitis following antivascular endothelial growth factor (VEGF) injection. METHOD: The authors retrospectively reviewed the medical records of all patients in their practice with a diagnosis of endophthalmitis from January 1, 2007, through December 31, 2011. Only those with a clinical presentation consistent with endophthalmitis after intravitreal anti-VEGF injection were included. Clinical data that were collected and recorded included visual acuities and the method of initial and subsequent treatment of endophthalmitis following anti-VEGF injection: tap and injection of intravitreal antibiotics (TAP) and tap and inject with subsequent pars plana vitrectomy (VIT). RESULTS: The authors identified 23 patients meeting criteria. Nineteen patients had received bevacizumab and four patients had received ranibizumab. The median time from last injection to presentation was 4 days (range, 1-18 days) with a median follow-up of 15 months (range, 5-48 months) after being diagnosed of endophthalmitis. Nine patients had positive cultures. The median baseline visual acuity (preendophthalmitis) was 20/70 (range, 20/25 to counting fingers at 2 ft) with a median presenting visual acuity of counting fingers at 1 ft (range, 20/50 to light perception vision). Overall, 90% (9/10) of the patients in TAP only group regained visual acuity within 1 line or better of baseline versus 46% (6 of 13) in the TAP and VIT group. Only one of the patients treated with TAP alone suffered more than one line of visual acuity loss. CONCLUSION: Patients diagnosed with endophthalmitis after anti-VEGF intravitreal injection who underwent TAP regained baseline visual acuity more often than those who underwent TAP and VIT. This study did not support a benefit for VIT in all patients, rather only in those cases who warranted it because of worsening clinical course. The study suggests that TAP is a viable primary intervention for endophthalmitis after anti-VEGF injection.

PURPOSE: The purpose of this study was to report the findings of a hyperreflective nodular epiretinal gliosis observed with optical coherence tomography presumed to be due to subclinical hyaloidal traction causing MÏller cell cone gliosis. METHODS: Retrospective, observational case series. RESULTS: Six eyes of six patients (mean age: 57 years, range 35-81 years) presented with a nodular epiretinal gliosis and had an average follow-up interval of 26 months (range 1-82 months). The mean baseline best-corrected visual acuity was 0.25 ± 0.17 (Snellen equivalent 20/38.3 ± 16.9). Fundus photography demonstrated a yellowish lesion overlying the fovea. Optical coherence tomography imaging revealed a hyperreflective preretinal lesion with a mean vertical length of 267 µ m (range 185-497) and a mean greatest linear diameter of 312 µ m (range 124-640). There was no vitreoretinal abnormality including vitreomacular traction or epiretinal membrane noted in any eye, and two of six eyes displayed a definitive posterior vitreous detachment. These nodules may have occurred before and persisted even after a posterior vitreous detachment or may have been acquired after the posterior vitreous detachment. The nodules typically remained stable with minimal change although in one eye, a posterior vitreous detachment occurred 6 months after initial presentation and lifted the gliosis off of the retinal surface where it remained attached to the posterior hyaloid. CONCLUSION: Foveal nodular epiretinal gliosis may occur due to subclinical hyaloidal traction on the Müller cell cone even without obvious vitreoretinal interface abnormality on optical coherence tomography.

BACKGROUND: Access to health care is a well-recognized issue in health policy, but use once patients have entered the health care system is uncommonly addressed. METHODS: We performed a retrospective review of children between 2 and 17 years of age with pathologically confirmed appendicitis at our public city hospital and private university hospital and compared management and outcomes. RESULTS: Among patients with acute appendicitis, the median length of stay was a day longer in the public hospital (2 days vs 1 day, P = <.001) despite a similar complication rate (12% vs 11%). More computed tomography (CT) scans were performed at the public hospital (36% vs 21%, P = .02) with a trend toward less use of ultrasound (US) (54% vs 65%, P = .13). CONCLUSIONS: Children at the public city hospital have a longer length of stay and undergo more expensive imaging. These findings may provide areas for improvement to optimize the care of children with appendicitis at government-funded institutions.

PURPOSE: To compare latencies of conventional visual evoked potentials (cVEPs) and multifocal VEPs (mfVEPs) in the same patients. Previous reports of prolonged cVEP latency suggest a vehicle for detecting abnormal ganglion cells and for monitoring neuroprotection. METHODS: Seventy-five glaucomatous eyes (47 patients), 75 eyes with suspected glaucoma (46 patients), and 41 control eyes (22 subjects) underwent achromatic automated perimetry and mfVEP and cVEP testing. The mfVEP stimulus was a scaled dart board with 60 sectors; each sector was a pattern-reversing checkerboard. The cVEP stimulus was a reversing checkerboard with checks of either 15 minutes or 60 minutes in width. RESULTS: Relatively few glaucomatous eyes had latencies that fell outside the range of control eyes, and there was little difference between the cVEP and mfVEP results. In the glaucoma group, 12.3% (15 minutes cVEP), 8% (60 minutes cVEP), and 17.3% (mfVEP) of the eyes and 5.3% (15 minutes cVEP), 6.7% (60 minutes cVEP), and 5.3% (mfVEP) of the suspect eyes exceeded the normal range. The glaucomatous eyes had, on average, relatively small increases in latency, compared with the control or suspect groups. Further, the latency of both the mfVEP and cVEP bore no obvious relationship to the mean deviation of the visual field. CONCLUSIONS: Contrary to previous reports, prolonged VEP delays were present in a minority of patients with glaucoma. Either a delayed VEP is not a good indicator of damaged, as opposed to dead, retinal ganglion cells, or there are relatively few patients who exhibit evidence of damaged ganglion cells.

AIM: To investigate patients' sensory phenomena, especially instrument visualisation, and their emotional reactions during pars plana vitrectomy (PPV) under monitored anaesthesia care (MAC). METHODS: One hundred adults who underwent PPV under MAC plus peribulbar block were prospectively recruited on the day after surgery to complete a questionnaire about sensory phenomena and comfort. Anaesthetics used during surgery were correlated with visual phenomena and patient comfort. Surgeons were asked to predict patient intraoperative comfort and ability to hear. RESULTS: Of the 27% of patients who reported visual phenomena, lights (74%), colours (37%) and moving instruments (17%) were common. Instrument visualisation was not associated with any preoperative or intraoperative variables. Visual phenomena were neutrally received by 98% of patients. Neither the use of the intravenous medications during the peribulbar injection and surgery nor the type of local anaesthesia correlated with perceived level of pain. Sixty-six per cent of patients remembered hearing surgeons talk, and 96% of patients reacted neutrally to voices. Patient reports of intraoperative pain were similar to the surgeon's prediction, and mean discomfort during surgery was mild. CONCLUSIONS: The reported prevalence of intraoperative visual phenomena is low when elicited at the first postoperative visit. Surgeons can reliably predict patients' comfort, and most patients react neutrally to visual and hearing phenomena during PPV under MAC with peribulbar block. The combination of medications used may be responsible for the neutral reception of sensory phenomena.

PURPOSE: To determine the effect of optic disc drusen on the latency of the pattern-reversal checkerboard visual evoked potentials (VEPs) and multifocal (mf)VEPs and to better understand the pathophysiology of the condition. METHODS: Eighteen eyes with optic disc drusen (10 patients) and 38 control eyes (19 subjects) underwent VEP, mfVEP, and visual field testing. Only one eye of each individual, the one with the more affected visual field, was used in the analyses. The VEPs were recorded with a 15' and 60' reversing checkerboard pattern, and the mfVEPs were elicited by a 60-sector dartboard display. RESULTS: Unlike the VEP results, the mfVEP revealed a significant increase in the average monocular latency of the optic disc drusen group compared with that of the control group. The average mfVEP relative latency for the optic disc drusen group (4.1 ms) was greater than that (0.8 ms) in the control group. For monocular and interocular analyses, the average percentage of points delayed in the drusen group was significantly greater than that in the control group. CONCLUSIONS: Optic disc drusen produced significant latency delays on the mfVEP test but not on the VEP test, presumably due to the mfVEP's ability to detect the effects of local changes. The results are consistent with the hypothesis that local mechanical compression by optic disc drusen leads to abnormal retinal ganglion cell activity.

Struma ovarii is rare ovarian tumor that is characterized by the presence of at least 50% thyroid tissue on histologic examination. This usually benign neoplasm is predominantly found in women between the ages of 40 and 60 years and infrequently in the pediatric age group. In the foregoing report, we present an unusual case of a large struma ovarii in a 16-year-old adolescent girl with abdominal pain and increasing abdominal girth. Removal of the mass was achieved via a laparoscopic approach. We conclude that the diagnosis of struma ovarii should be considered in adolescent girls presenting with large cystic ovarian masses and that a laparoscopic approach to management is the treatment of choice.
