ABSTRACT

PurposeTo examine 12-month real-world visual acuity outcomes and treatment patterns in neovascular age-related macular degeneration (nAMD) eyes, including those with pigment epithelial detachment (PED), receiving ranibizumab or aflibercept.Patients and methodsElectronic medical records were used to identify ranibizumab or aflibercept-treated nAMD eyes with 12 months follow-up from first prescription. The primary objective was to compare mean change in visual acuity (VA) between index and month 12, in eyes treated with ranibizumab and aflibercept to assess the non-inferiority of ranibizumab vs aflibercept using a -5 letter non-inferiority margin. The number of injections and non-injection visits during follow-up were key secondary objectives.ResultsA total of 3350 ranibizumab and 4300 aflibercept treatment-naive eyes were included. At month 12, mean change from index in VA letter score was -0.30 for ranibizumab and -0.19 for aflibercept (P=0.81). The adjusted difference of mean change was -0.14 (-0.79 to 0.51) (P=0.67) (generalized estimating equations method) confirming the non-inferiority of ranibizumab. Eyes received a similar number of injections during follow-up. The mean (±SD) number of ranibizumab and aflibercept injections were 6.70 (±2.54) and 7.00 (±2.40), respectively (P<0.0001). In PED eyes, the mean (±SD) change between baseline to month 12 was 1.25 (±11.3) for ranibizumab and -0.39 (±13.3) for aflibercept (adjusted between-group difference 1.80 (-0.71 to 4.30; P=0.16)) achieved with a mean (±SD) 7.85 (±2.68) ranibizumab and 7.47 (±2.45) aflibercept injections, (P=0.11).ConclusionsRanibizumab and aflibercept treatment yielded comparable VA outcomes in nAMD eyes, including those with PED, with similar treatment patterns over 12 months in real-world clinical practice.

ABSTRACT

PURPOSE: Diabetic macular oedema (DMO) is a leading cause of blindness in working-age adults. Slow-release, nonbioerodible fluocinolone acetonide (FAc) implants have shown efficacy in the treatment of DMO; however, the National Institute for Health and Care Excellence recommends that FAc should be used in patients with chronic DMO considered insufficiently responsive to other available therapies only if the eye to be treated is pseudophakic. The goal of this analysis was to examine treatment outcomes in phakic patients who received 0.2 µg/day FAc implant. METHODS: This analysis of the phase 3 FAME (Fluocinolone Acetonide in Diabetic Macular Edema) data examines the safety and efficacy of FAc implants in patients who underwent cataract extraction before (cataract before implant (CBI) group) or after (cataract after implant (CAI) group) receiving the implant. The data were further examined by DMO duration. RESULTS: Best corrected visual acuity (BCVA) after 36 months was comparable in the CAI and CBI groups. Both the percentage of patients gaining ≥ 3 lines of vision and mean change in BCVA letter score were numerically greater in the CAI group. In addition, most patients who underwent cataract surgery experienced a net gain in BCVA from presurgery baseline as well as from original study baseline. CONCLUSIONS: These data support the use of 0.2 µg/day FAc implants in phakic as well as in pseudophakic patients. These findings will serve as a pilot for design of future studies to evaluate the potential protective effect of FAc implants before cataract surgery in patients with DMO and cataract.

ABSTRACT

Juvenile xanthogranuloma (JXG) is a rare, pediatric histiocytic skin disorder that may affect the eye. It can present with protean ocular manifestations, including masquerade uveitis, heterochromia, hyphema, or glaucoma. It very rarely involves the retina and posterior segment; indeed, posterior involvement has been documented histopathologically in only one case. We present the case of a 2-year-old child with ocular JXG presenting as chronic, refractive uveitis, without skin or systemic findings. The blind, painful eye was enucleated and found to harbor a diffuse histiocytic process that involved both the anterior and posterior segments, including the retina and subretinal space. Histological, immunohistochemical, and electron microscopic studies confirmed the diagnosis of JXG. The pathologic classification and differential diagnosis of systemic histiocytic disorders are discussed. Since JXG can present as masquerade pediatric uveitis, this entity should be considered in children with atypical uveitis. In rare instances, JXG may involve the posterior segment and the retina, leading to retinal detachment and blindness.

ABSTRACT

PURPOSE: To report the intraoperative occurrence of massive intraocular suprachoroidal hemorrhage associated with Valsalva maneuver. METHODS: Retrospective, multicenter study of patients who developed massive choroidal hemorrhage associated with Valsalva maneuver during vitrectomy. RESULTS: Massive intraoperative suprachoroidal hemorrhage in seven patients (seven eyes) involved three men and four women with a median age of 52 years (range, 26 to 82 years). General anesthesia was used in six of seven cases. Coughing or "bucking" on the endotracheal tube during general anesthesia or severe coughing during the one vitrectomy performed under local anesthesia was associated with massive suprachoroidal hemorrhage. In five of seven eyes, this occurred near the end of surgery, after air-fluid exchange but before sclerotomy closure. Scleral plugs were immediately placed, and sclerotomy closure was performed exigently. Immediate posterior sclerotomy was performed on five of seven eyes; an additional patient underwent posterior sclerotomy postoperatively. After median follow-up of 18 months (range, 3 to 36 months), final visual acuity was no light perception in four eyes, light perception in one eye, 20/250 in one eye, and 20/20 in one eye. Four eyes became phthisical. CONCLUSIONS: Valsalva maneuver during pars plana vitrectomy may result in massive suprachoroidal hemorrhage with disastrous visual consequences. Precautionary measures to prevent coughing or "bucking" on the endotracheal tube during general anesthesia, or a prolonged episode of coughing during local anesthesia, may prevent this potentially devastating complication.

ABSTRACT

OBJECTIVE: This study evaluated the visual outcome and complications of repositioning and sulcus fixation of a dislocated posterior chamber intraocular lens (PC IOL) using a technique in which the haptics of the IOL are temporarily externalized for suture placement. DESIGN: Retrospective, noncomparative case series. PARTICIPANTS: Seventy-eight patients with a dislocated PC IOL. INTERVENTION: All patients underwent surgery to fixate the PC IOL using this technique. MAIN OUTCOME MEASURES: Patients were evaluated for visual acuity, refractive error, and surgical complications associated with the procedure. RESULTS: The average visual acuity before surgery was 20/205 (range, 20/20 to light perception), with a median refractive error of -1.00 diopters (D; range, -7.25-+15.00 D). After surgery, the average visual acuity improved to 20/72 (range, 20/20 to no light perception), with a median refractive error of -0.75 D (range, -5.50-+3.50 D). Patients were observed for a median of 15.5 months (range, 6-57 months). Twenty patients had postoperative cystoid macular edema (26%), 7 patients had an epiretinal membrane (ERM) (9%), and 5 patients had a retinal detachment (6%). Eight patients (10%) experienced iris capture of the sutured IOL, and in three patients (4%) the PC IOL dislocated again after surgery. CONCLUSIONS: This technique is an effective method for securing a dislocated PC IOL.

ABSTRACT

OBJECTIVE: To report the anatomic and visual results of primary pars plana vitrectomy (PPV) without scleral buckling to repair primary rhegmatogenous retinal detachments in pseudophakic eyes. DESIGN: Nonrandomized, prospective, comparative clinical trial. PARTICIPANTS: Two hundred eighty-three consecutive patients (294 eyes) with pseudophakia, peripheral retinal tears, and new rhegmatogenous retinal detachments were treated according to the surgery protocol. INTERVENTION: Patients underwent PPV with fluid-gas exchange and endolaser to repair the retinal detachment. Two hundred sixty-four patients (275 eyes) were followed from 6 months to 6 years and 8 months with an average follow-up of 19 months. MAIN OUTCOME MEASURES: Reattachment of the retina and visual outcome were compared to previously published studies. RESULTS: Of 97 eyes with a macula-attached rhegmatogenous retinal detachment, 88 eyes (91%) were reattached with a single operation, and of the 178 eyes with a macula-detached retinal detachment, 153 (86%) eyes were reattached with a single operation. In 241 (88%) of 275 eyes, the retina was reattached with a single operation, and in 265 (96%) of 275 eyes, the retina was ultimately reattached with subsequent operations. The median initial visual acuity was 20/300, and the median final visual acuity was 20/40. The rate of reattachment with one operation was similar for eyes with an anterior chamber intraocular lens (91%) and for eyes with a posterior chamber intraocular lens (88%). Refractive error measurements obtained in 81 eyes were essentially unchanged. The mean change in refractive error was -0.15 diopter. Seventeen eyes (6%) developed macular puckers requiring surgery, 46 eyes (17%) developed cystoid macular edema, and 6 eyes (2%) developed full-thickness macular holes. CONCLUSION: Primary PPV with fluid-gas exchange and laser is a safe, effective method to repair primary pseudophakic retinal detachments. The anatomic reattachment rate and the visual acuity obtained with this technique appear to be at least as good as those reported in the literature for scleral buckling, PPV with scleral buckling, and pneumatic retinopexy.

ABSTRACT

OBJECTIVE: To examine the results of macular hole surgery using pars plana vitrectomy, internal-limiting membrane peeling, and intravitreous air in a series of consecutive patients. DESIGN: A retrospective, interventional, noncomparative case series. PATIENTS: Fifty consecutive patients (58 eyes) with full-thickness macular holes. INTERVENTION: All eyes underwent a pars plana vitrectomy with internal-limiting membrane peeling and intravitreous air, and patients were asked to position face-down for only 4 days. MAIN OUTCOME MEASURES: Status of macular holes, visual acuity, and associated findings and complications. RESULTS: All patients had postsurgical follow-up of 6 months or greater. Eight eyes (14%) presented with stage-2 macular holes, 48 eyes (83%) with stage-3 macular holes, and 2 eyes (3%) with stage-4 macular holes. Only 26 eyes (45%) had a macular epiretinal membrane seen before surgery. Fifty-three (91 %) of the 58 macular holes were closed with 1 operation, and 55 (95%) had closure of the macular holes with subsequent operations. Five (9%) of 58 eyes had an initial visual acuity of 20/50 or better, and 31 eyes (53%) had a final visual acuity of 20/50 or better. Of the 45 eyes with symptoms of less than 6 months' duration, 44 (98%) had macular holes that were closed with 1 operation and 27 (60%) had a final visual acuity of 20/50 or better. Of the 13 eyes with symptoms of 6 months' duration or longer, 9 (69%) had macular holes that were closed with 1 operation and 4 (31 %) had a final visual acuity of 20/50 or better. Complications attributed to the operation included retinal tears, retinal detachments, postoperative macular puckers, and macular light toxicity. CONCLUSIONS: The anatomic and visual results in this series are good. The current technique is similar to that of conventional macular hole surgery except for the use of intravitreous air, internal-limiting membrane peeling in all eyes, and only 4 days of postoperative positioning. This study would suggest that peeling of the internal-limiting membrane is an important adjuvant for successful closure of macular holes.

ABSTRACT

OBJECTIVE: To evaluate the ocular effects of blunt trauma due to injury from a paintball pellet. DESIGN: Noncomparative case series. PARTICIPANTS: Thirteen patients who suffered ocular injury from paintballs are described. The patients presented to six different civilian and military emergency departments in tertiary care medical centers. INTERVENTION: Patients were treated for the ocular injury. MAIN OUTCOME MEASURES: Patients were evaluated for initial and final visual acuity. The reason for persistent loss of vision was delineated. RESULTS: There were 12 males and 1 female with an average age of 21 years (range, 12-33 years). Eleven of the 13 had no ocular protection at the time of the ocular injury. On initial examination, nine patients had a hyphema, nine had a vitreous hemorrhage, six had a retinal tear or detachment, three had corneal or corneal-scleral ruptures, and one had traumatic optic neuropathy. The final visual acuity was 20/40 or better in two patients, 20/50 to 20/150 in three patients, and 20/200 or worse in eight patients. CONCLUSION: Injuries due to paintball pellets can result in severe ocular damage and significant loss of vision. Eyecare professionals should be aware of the risks of this sport and must strongly advise participants to wear adequate protection when involved in this activity.

ABSTRACT

OBJECTIVE: The objective is to compare the effectiveness of retrobulbar and posterior sub-Tenon's injection of corticosteroids for treatment of post-cataract cystoid macular edema that was refractory to topical medications. DESIGN: A retrospective study was performed. PARTICIPANTS: A total of 48 patients (49 eyes) with post-cataract cystoid macular edema refractory to topical medications was studied. INTERVENTION: Patients received either a single retrobulbar injection (18 eyes) or 3 biweekly posterior sub-Tenon's injections (31 eyes) of corticosteroids. MAIN OUTCOME MEASURES: Patients were observed for clinical resolution of the cystoid macular edema, visual acuity, and intraocular pressure. RESULTS: Both treatment methods resulted in significant improvement in visual acuity. The posterior sub-Tenon's group had a visual improvement from 20/92 pretreatment to 20/50 post-treatment (P = 0.0001) with a median follow-up of 12 months. The retrobulbar group had a visual improvement from 20/97 pretreatment to 20/58 post-treatment (P = 0.035) with a median follow-up of 10 months. The visual improvement was not significantly different between the two groups. The average intraocular pressure increased from a pretreatment level of 14.1 mmHg to a high of 17.7 mmHg (P < 0.00005) in the sub-Tenon's group. The average intraocular pressure increased from 15.1 mmHg to a high of 17.6 mmHg (P = 0.04) in the retrobulbar group. CONCLUSIONS: Cystoid macular edema that persists after treatment with topical medications may improve after retrobulbar or posterior sub-Tenon's corticosteroid injections. There was no significant difference in outcome between the two treatment groups.

ABSTRACT

PURPOSE: The purpose of the study was to define a newly recognized complication after glaucoma surgery and to recommend a therapeutic regimen. METHODS: Eighteen patients diagnosed initially as having aqueous misdirection after glaucoma surgery, but who subsequently were found by ultrasonography to have an annular peripheral choroidal detachment that resulted in secondary angle closure glaucoma, were studied. Ten of these patients were treated with topical cycloplegics and corticosteroids, and 8 were treated with drainage of suprachoroidal fluid. Outcomes of these two treatment methods were compared. RESULTS: Annular peripheral choroidal detachment reliably was diagnosed with ultrasonography. Of the variables studied, time elapsed before resolution of the annular peripheral choroidal detachment was noted to be statistically significant (P < 0.00005). Immediate resolution followed drainage of suprachoroidal fluid, whereas a mean of 19.6 days was required for resolution after medical therapy. CONCLUSIONS: Annular peripheral choroidal detachment should be considered in the differential diagnosis of a flat or shallow anterior chamber with normal or high intraocular pressure after glaucoma surgery. The diagnosis of annular peripheral choroidal detachment can be confirmed most reliably by ultrasonography. Medical therapy is as effective as is surgery, although a significantly longer time to resolution is required.

ABSTRACT

PURPOSE: Disseminated cryptococcosis is a major cause of morbidity and mortality in immunocompromised individuals, especially those with the acquired immunodeficiency syndrome (AIDS). Early diagnosis and treatment greatly improves the outcome, so clinical clues that lead to prompt diagnosis are important. METHODS: Three patients with AIDS in whom multifocal choroiditis and choroidal lesions were the initial signs of disseminated cryptococcosis were treated with systemic amphotericin B and flucytosine. All of the patients had a systemic work-up that included evaluation of the cerebral spinal fluid (CSF). RESULTS: All three patients who were seen with the choroidal lesions as the presenting sign were noted to have either positive titers for cryptococcus or cultures that grew cryptococcus in the CSF. The choroidal lesions are presumed to be due to cryptococcus as no histopathologic or microscopic studies were available for ocular tissues. The choroidal lesions started to resolve one to three months after systemic treatment with amphotericin B and flucytosine. CONCLUSION: Primary choroidal lesions in patients with AIDS may herald severe systemic disseminated disease. Funduscopic examination, however, may detect disseminated cryptococcal disease before other overt clinical manifestations, thereby allowing prompt institution of effective therapy.

ABSTRACT

Both in vitro and in vivo studies have implicated a role for tumor necrosis factor-alpha (TNF alpha) in various demyelinating diseases, including HIV-related encephalopathy. To investigate whether intravitreal TNF alpha can induce optic nerve axonal damage in a rabbit eye model, fifteen rabbit eyes were initially injected with TNF alpha (final concentrations: 2U, 20U, and 200U respectively) and studied at varying time intervals for up to 24 weeks post-injection, using light and electron microscopy. Control optic nerves (no injection or diluent injection only) had normal myelinated axons and glia; the myelinated regions, neural retina, retinal glia and vasculature of control retinas were normal. In TNF alpha-exposed optic nerves, intact, degenerating and demyelinated axons were interspersed. Astrogliosis was present, particularly from 8 weeks p.i. and was noted up to 24 weeks. Oligodendrocytes were not severely affected in TNF alpha-exposed optic nerves, and activated macrophages or microglia were not obvious. Axonal degeneration was visible among the more superficial myelinated fibers in TNF alpha-exposed retinas however the neural retina glia were unaffected. These observations suggest that the axonal degeneration induced in TNF alpha-exposed rabbit optic nerves over a 24 week period was most likely related to direct effects of TNF alpha on optic nerve axons, and not primarily due to anterograde degeneration from retinal lesions. In-so-far as neurological pathology in general, and optic nerve degeneration in particular, has been described in AIDS, and TNF alpha levels may be elevated in this disease, it is of great clinical significance that TNF alpha has the capacity to mediate neuronal or axonal injury. If so, strategies to block or inhibit TNF alpha can be pursued for treatment for the neurological symptoms of AIDS.

ABSTRACT

PURPOSE: We reviewed the clinical and histopathologic features of 33 intraocular tissue biopsy specimens from 32 patients and assessed the value of retinal and chorioretinal biopsies performed in patients with intraocular inflammation. METHODS: Twenty-four endoretinal biopsies and nine chorioretinal or choroidal biopsies were performed. On the basis of clinical indications, the specimens were processed for light microscopy, electron microscopy, immunohistochemical staining, in situ DNA hybridization, and polymerase chain reaction. RESULTS: Of the 24 endoretinal biopsy specimens, 19 were from patients with clinical signs suggestive of viral retinitis. Overall, the diagnosis of viral retinitis was suggested by electron microscopy, immunohistochemical staining, in situ DNA hybridization, or polymerase chain reaction in 53% (ten of 19) biopsies. The preoperative diagnosis was confirmed in seven of ten biopsies in cases of suspected cytomegalovirus retinitis, in one of seven biopsies in cases of suspected acute retinal necrosis, and in two of two biopsies in cases of progressive outer retinal necrosis. The remaining five endoretinal biopsies disclosed Candida in one specimen, subretinal fibrosis in one, and chronic inflammation in three. Histologic examination of the nine chorioretinal or choroidal biopsies disclosed lymphoma in two specimens, a subretinal neovascular membrane in one, uveal melanocytic proliferation in one, toxoplasmic retinochoroiditis in one, viral retinitis in one, and long-standing inflammation in three. CONCLUSION: In select cases of intraocular inflammation, intraocular tissue biopsies may provide clinically useful information.

ABSTRACT

OBJECTIVE: To correlate the initial echographic findings in eyes with infectious endophthalmitis with the visual prognosis and causative microorganism. DESIGN: A retrospective review of the clinical and standardized ocular echographic findings in eyes with infectious endophthalmitis was performed. SETTING: University-based ophthalmology department. STUDY PARTICIPANTS: One hundred thirty-seven eyes (136 patients) with infectious endophthalmitis that were evaluated by the ocular echography service of the Doheny Eye Institute, Los Angeles, Calif, between January 1, 1981, and December 31, 1992. RESULTS: Four findings on initial echography were associated with poor initial vision: dense vitreous opacities, retinal detachment, macular detachment, and choroidal detachment. Five findings on initial echography correlated with poor final vision: dense vitreous opacities, vitreous membranes, the presence of retinal detachment, the extent of retinal detachment, and the presence of choroidal detachment. Change (decrease) in vision during the follow-up period was associated with the presence of combined vitreous and subhyaloid opacities, retinal detachment, and choroidal detachment. All eyes with initially clear vitreous on ocular echography had either early streptococcal or culture-negative endophthalmitis. Advanced streptococcal endophthalmitis correlated with the most severe vitreous inflammation, vitreous membranes, and the most extensive posterior vitreous detachment, whereas gram-negative endophthalmitis correlated with choroidal detachment on initial echography. Stepwise logistic regression analysis revealed that the presence of choroidal detachment, not gram-negative microorganisms, was the principal predictor of poor visual outcome in these eyes. CONCLUSION: Ocular echography is a useful method in the clinical evaluation and treatment of infectious endophthalmitis, especially in eyes with opaque media.

ABSTRACT

Human T-cell lymphotropic virus type I has been associated with a wide range of ocular conditions, including neoplastic, infectious, and inflammatory lesions. We studied a patient infected with human T-cell lymphotrophic virus type I who presented with deep retinal and subretinal infiltrates but without cells in the vitreous. The differential diagnosis included intraocular lymphoma and fungus infection. A chorioretinal biopsy specimen obtained for tissue diagnosis disclosed large atypical mononuclear cells located primarily at the level of the retinal pigment epithelium but focally involving overlying retina. Electron microscopy of this infiltrate showed features consistent with adult T-cell lymphoma/leukemia. Infection by human T-cell lymphotropic virus type I was verified by polymerase chain reaction studies conducted on peripheral-blood mononuclear cells. This case emphasizes the occurrence of intraocular lesions in adult T-cell lymphoma/leukemia that clinically show some features similar to those of the usual ocular lymphoma (reticulum cell sarcoma); diagnosis can be established by chorioretinal biopsy, thereby allowing appropriate therapy.

ABSTRACT

BACKGROUND: Anatomic characteristics of macular holes may be difficult to define, even with contact lens biomicroscopy. With the advent of successful macular hole surgical techniques, accurate diagnosis has become increasingly important to avoid unnecessary or incorrect surgery. Echography may provide additional diagnostic information in some cases. The purpose of this study is to correlate echographic and intraoperative clinical features of macular holes. METHODS: The echographic features and intraoperative findings in 25 patients were compared. The spectrum of identifiable echographic features included (1) a thin, smooth, membrane-like surface minimally elevated over the macula (limited posterior vitreous face separation); (2) macular thickening; (3) an operculum; and (4) a complete posterior vitreous face separation. Intraoperative clinical findings included the presence or absence of (1) a thin, limited posterior vitreous face separation, (2) a subretinal fluid cuff, (3) an operculum, and (4) a complete posterior vitreous face separation. RESULTS: Echographic and intraoperative findings correlated regarding the limited posterior face separation in 23 of 25 patients, a surrounding subretinal fluid cuff (macular thickening) in 24 of 25 patients, an operculum in 19 of 25 patients, and complete posterior vitreous face separation in 24 of 25 patients. Thus, echography was very effective in detecting the position of the posterior vitreous face. Overall, echography correlated accurately with 90 (90%) of 100 of these four features. CONCLUSION: Echographic features correlate accurately with clinical features.

ABSTRACT

BACKGROUND: The Molteno implant is a device used for surgical treatment of complicated glaucoma. Rhegmatogenous retinal detachment (RD) is a relatively rare complication of Molteno implant surgery. This study was undertaken to evaluate the clinical features including the surgical management and postoperative outcome of patients with rhegmatogenous RD after Molteno implant surgery. METHODS: The authors reviewed 350 consecutive patients who had Molteno surgery and identified 16 patients with subsequent rhegmatogenous RD. They also studied one patient referred for RD repair after Molteno surgery at another institution. RESULTS: The risk of rhegmatogenous RD was 5%. Seventy percent (12/17) of the patients presented within 4 months of the Molteno procedure. Dialysis and flap tear were the most common types of retinal break found. Forty-one percent (7/17) of the patients had proliferative vitreoretinopathy. In three patients, clinical features suggested RD resulting from the Molteno procedure. In other patients, previous ocular surgery and underlying ocular disease may have contributed to the development of RD. Retinal detachment repair was attempted in all patients. Among 16 patients with at least 6 months of follow-up, 56% (9/16) had successful retina attachment. Forty-four percent (7/16) of the patients maintained formed vision. Eighteen percent (3/16) of the patients maintained visual acuity of at least 20/40. Intractable glaucoma did not develop in any of the patients with an attached retina. Recurrent RD, endophthalmitis, cyclitic membrane, or intractable glaucoma led to phthisis bulbi or enucleation in 44% (7/16) of the patients. CONCLUSION: A combined approach by vitreoretinal and glaucoma surgeons can restore vision and maintain glaucoma control in patients with rhegmatogenous RD associated with Molteno implant surgery.
