RESUMEN

PURPOSE: The LIGHTSITE III study evaluated multiwavelength photobiomodulation (PBM) therapy in nonexudative (dry) age-related macular degeneration (AMD) using the LumiThera Valeda Light Delivery System. METHODS: LIGHTSITE III is a randomized, controlled trial to assess the safety and effectiveness of PBM in dry AMD. Subjects were given multiwavelength PBM (590, 660, and 850 nm) or Sham treatment delivered in a series of nine sessions over 3 to 5 weeks every four months over 24 months. Subjects were assessed for efficacy and safety outcomes. Data from the 13-month analysis are presented in this report. RESULTS: A total of 100 subjects (148 eyes) with dry AMD were randomized. LIGHTSITE III met the primary efficacy best-corrected visual acuity endpoint with a significant difference between PBM (n = 91 eyes) and Sham (n = 54 eyes) groups (Between group difference: 2.4 letters (SE 1.15), CI: -4.7 to -0.1, P = 0.02) (PBM alone: 5.4 letters (SE 0.96), CI: 3.5 to 7.3, P < 0.0001; Sham alone: 3.0 letters (SE 1.13), CI: 0.7-5.2, P < 0.0001). The PBM group showed a significant decrease in new onset geographic atrophy ( P = 0.024, Fisher exact test, odds ratio 9.4). A favorable safety profile was observed. CONCLUSION: LIGHTSITE III provides a prospective, randomized, controlled trial showing improved clinical and anatomical outcomes in intermediate dry AMD following PBM therapy.

RESUMEN

Importance: Despite the effectiveness of existing anti-vascular endothelial growth factor (VEGF) therapies, a need remains for further treatment options to improve response rates and/or reduce injection or monitoring frequency in patients with diabetic macular edema (DME). Objective: To evaluate the efficacy and safety of brolucizumab vs aflibercept dosed every 4 weeks in participants with DME. Design, Participants, and Setting: This 52-week, double-masked, phase 3 randomized clinical trial included treatment-naive adults and adults who had previously received anti-VEGF therapy. Data were collected from September 2019 to March 2020, and data were analyzed from April 2020 to February 2021. Intervention: Brolucizumab, 6 mg, intravitreal injection every 4 weeks or aflibercept, 2 mg, intravitreal injection every 4 weeks. Main Outcomes and Measures: Participants were randomized 2:1 to brolucizumab, 6 mg, or aflibercept, 2 mg. The primary end point was change from baseline in best-corrected visual acuity at week 52. Secondary end points were the proportion of participants with a 2-step improvement or greater from baseline in Diabetic Retinopathy Severity Scale score, the proportion of eyes with absence of both subretinal fluid and intraretinal fluid, change from baseline in central subfield thickness, and safety at week 52. Results: A total of 517 participants were randomized to brolucizumab (n = 346) or aflibercept (n = 171); 299 (57.8%) were male, and the mean (SD) age was 60.7 (10.2) years. Brolucizumab was noninferior to aflibercept in best-corrected visual acuity (Early Treatment Diabetic Retinopathy Study letter score) change from baseline at week 52 (brolucizumab, 12.2-letter improvement; aflibercept, 11.0-letter improvement; difference, 1.1; 95% CI, -0.6 to 2.9; noninferiority margin, 4; P < .001). Brolucizumab was superior to aflibercept for the proportion of eyes without subretinal and intraretinal fluid (brolucizumab, 144 of 346 [41.6%]; aflibercept, 38 of 171 [22.2%]; difference, 20.0%; 95% CI, 12.5to 28.6; P < .001) and mean central subfield thickness change from baseline at week 52 (brolucizumab, -237.8 µm; aflibercept, -196.5 µm; difference, -41.4; 95% CI, -58.9 to -23.8; P < .001). Incidence of intraocular inflammation was 4.0% (14 of 346) in the brolucizumab arm and 2.9% (5 of 171) in the aflibercept arm, incidence of retinal vasculitis was 0.9% (3 of 346) and 0.6% (1 of 171), respectively, and incidence of retinal vascular occlusion was 0.3% (1 of 346) and 0.6% (1 of 171). One participant in the brolucizumab arm had retinal artery occlusion. Conclusions and Relevance: In these study participants with DME, no clinically meaningful differences in visual outcomes were noted between the brolucizumab and aflibercept arms; some superior anatomic improvements were noted in the brolucizumab arm. No new safety concerns were identified. Trial Registration: ClinicalTrials.gov Identifier: NCT03917472.

RESUMEN

PURPOSE: To determine treatment outcomes of intravitreal ocriplasmin in symptomatic vitreomacular adhesion. DESIGN: Retrospective interventional case series. METHODS: setting: Private practice. study population: Thirty-five eyes (35 subjects) with symptomatic vitreomacular adhesion. intervention/observation: Intravitreal ocriplasmin injection from February to November 2013. main outcome measure: Vitreomacular adhesion resolution rate. Secondary endpoints included postinjection visual acuity and rates of outer retinal attenuation and full-thickness macular hole (MH) closure. RESULTS: The 35 subjects included were of mean age 69 years, 66% female, and 71% phakic. Eleven subjects (31%) had macular comorbidities. Average adhesion diameter was 571 µm, with mean 7.9 months duration of symptoms. Nine subjects (26%) had epiretinal membrane and 6 (17%) had MH (mean diameter 186 µm). Mean preinjection logarithm of the minimal angle of resolution visual acuity was 0.46, and improved to 0.33 at final follow-up. Fifteen eyes (43%) achieved adhesion release at mean 10 days post injection. One of 6 MH (17%) closed. Transient outer retinal attenuation occurred in 10 of 35 cases (29%), with 8 of 10 (80%) achieving adhesion release. One subject (3%) developed a retinal detachment. Adhesion resolution was more likely in patients with younger age (P = .04), absence of comorbidities (P = .02), small adhesion diameter (P = .005), short adhesion duration (P = .03), and transient outer retinal attenuation (P = .008). CONCLUSIONS: Intravitreal ocriplasmin efficacy in the private practice setting, while including patients with macular comorbidities, is similar to that of previous studies. Transient toxicity to the outer retina occurs frequently-typically with adhesion resolution-necessitating careful postinjection spectral-domain optical coherence tomography monitoring.

RESUMEN

PURPOSE: To determine the prevalence of herpes simplex virus type 1 (HSV-1) DNA in failed Descemet membrane stripping automated endothelial keratoplasty (DSAEK) grafts. METHODS: A retrospective interventional case series of patients with DSAEK graft failure treated at the New York Eye and Ear Infirmary between January 2009 and July 2012 was performed. Repeat DSAEK, penetrating keratoplasty, or keratoprosthesis procedure was subsequently performed on eyes with failed grafts. All failed grafts were examined immunohistochemically and with qualitative real-time polymerase chain reaction for HSV-1 DNA. In HSV-1-positive cases, corneoscleral donor rims from the original DSAEK procedures were also examined immunohistochemically and with polymerase chain reaction. RESULTS: Fifty-one failed DSAEK grafts from 50 eyes of 49 patients were identified. Indications for DSAEK were pseudophakic bullous keratopathy (28/51, 55%), Fuchs corneal endothelial dystrophy (12/51, 23%), failed penetrating keratoplasty (7/51, 14%), corneal decompensation from glaucoma (2/51, 4%), herpetic endotheliitis (1/51, 2%), and failed DSAEK (1/51, 2%). Forty-three grafts (83%) were primary DSAEK graft failure. HSV-1 DNA was isolated from 2 of 51 failed DSAEK grafts (4.0%). The corresponding corneoscleral donor rims did not demonstrate the presence of HSV-1. CONCLUSIONS: Based on our results, HSV-1 infection plays a minor role in DSAEK graft failure. The data suggest that recipient reactivation, rather than donor transmission, plays a role in HSV infection.

RESUMEN

PURPOSE: To report nine cases of pachychoroid pigment epitheliopathy. METHODS: An observational case series of nine patients who underwent comprehensive ophthalmic examination, fundus photography, fundus autofluorescence, spectral-domain optical coherence tomography, and enhanced depth imaging optical coherence tomography. RESULTS: Eighteen eyes of 9 patients, aged 27 years to 89 years, were diagnosed with pachychoroid pigment epitheliopathy based on the characteristic funduscopic appearance of reduced fundus tessellation with overlying retinal pigment epithelial changes in one or both eyes, fundus autofluorescence abnormalities, and increased subfoveal choroidal thickness confirmed by enhanced depth imaging optical coherence tomography (mean, 460.2 µm). The five older patients had been previously diagnosed with age-related macular degeneration, while the four younger subjects were referred for possible inflammatory chorioretinitis, pattern dystrophy, or nonspecific drusen. No subjects had a history of or subsequently developed subretinal fluid. CONCLUSION: Pachychoroid pigment epitheliopathy falls within a spectrum of diseases associated with choroidal thickening that includes central serous chorioretinopathy and polypoidal choroidal vasculopathy, and it should be suspected in eyes with a characteristic fundus appearance related to choroidal thickening and associated retinal pigment epithelial abnormalities but no history of subretinal fluid. Enhanced depth imaging optical coherence tomography confirming an abnormally thick choroid and characteristic retinal pigment epithelial changes on fundus autofluorescence support the diagnosis. Because these patients are frequently misdiagnosed, the recognition of pachychoroid pigment epitheliopathy may avoid unnecessary diagnostic testing and interventions.

RESUMEN

PURPOSE: To describe the clinical and pathologic characteristics of mucin-producing sweat gland carcinoma of the eyelid and to determine whether neuroendocrine differentiation is of prognostic significance. DESIGN: Retrospective interventional case series. METHODS: Search of the New York Eye and Ear Infirmary pathology database between 1990 and 2011 identified 16 patients with mucin-producing sweat gland carcinoma. Clinical, histopathologic, and immunohistochemical analyses were performed on all identified cases. RESULTS: The patients presented with vascularized, focally cystic, nonulcerated eyelid margin lesions. Histopathologic evaluation showed that 4 lesions (25%) had a cystic, papillary, and solid growth pattern with an in situ component, 7 (44%) were pure invasive mucinous carcinomas, and 5 (31%) demonstrated both growth patterns. Immunohistochemical analysis of 15 tumors showed that pure cystic/papillary lesions had a significantly greater percentage of synaptophysin-immunoreactive cells (P = .036). There was no significant difference in the number of neuroendocrine markers expressed or in the intensity of immunostaining among the 3 different growth patterns. Re-excision for margin clearance was performed in 8 of 13 cases (61.5%). Two of 13 lesions recurred (15%); 1 of these was an in situ tumor with cystic morphology and neuroendocrine differentiation and the other was pure invasive mucinous carcinoma. None of the lesions metastasized. CONCLUSIONS: Mucin-producing sweat gland carcinoma pathologically represents a continuum, from an in situ lesion to a classic, invasive mucinous carcinoma. Immunohistochemical evidence of neuroendocrine differentiation can be observed in all lesions and does not appear to have a prognostic significance, arguing against the utility of immunohistochemical subtyping of mucinous sweat gland carcinomas.
