Diabetic macular oedema (DMO) results from alterations of several biochemical pathways in diabetic eyes. Centre-involving DMO is an important cause of visual loss in diabetes. Anti-vascular endothelial growth factor agents are now the mainstay of centre-involving DMO treatment.

Methods: Single-center, randomized, subject-masked study of eyes with persistent diabetic macular edema, defined as central subfield thickness (CST) >340 μm despite ≥3 anti-vascular endothelial growth factors injections within 5 months. The intravitreal bevacizumab monotherapy (n = 23 eyes) and delayed delivery system monotherapy (n = 27 eyes) groups received treatments q1month and q3months, respectively.
Background And Objective: To compare a single image with a computer-generated summarized image from the ultra-wide-field fluorescein angiogram (UWFFA) sequence for evaluation of ischemic index (ISI).
Materials And Methods: UWFFA sequences from patients with diabetic retinopathy (DR) (n=5), branch retinal vein occlusion (BRVO) (n=5), and central retinal vein occlusion (CRVO) (n=5) were evaluated by six graders. A single image best illustrating retinal non-perfusion was compared to a summarized image generated by computerized superimposition of angiograms.
Objectives: Cytochrome P4502E1 (CYP2E1) is involved in the metabolism of isoniazid and the mediation of its hepatotoxicity. It exhibits genetic polymorphism in humans. This study evaluated the polymorphism of CYP2E1 in adult healthy Western Indians and patients on antituberculous drugs by phenotyping and genotyping.

Design: Cross-sectional study.
Participants: Patients with AMD treated at the vitreoretinal service clinic.
Background: Chordomas are rare, slow-growing malignant neoplasms derived from remnants of the embryological notochord. Pediatric cases comprise only 5% of all chordomas, but more than half of the reported pediatric chordomas are intracranial. For patients of all ages, intracranial chordomas typically present with symptoms such as headaches and progressive neurological deficits occurring over several weeks to many years as they compress or invade local structures.

Purpose: To evaluate the features and long-term outcomes of hydroxyapatite (HA) orbital implant following enucleation in pediatric patients.
Methods: A retrospective review was performed on clinical records of patients ≤18 years of age , managed with enucleation and HA implant placement. Recorded outcomes included implant-related complications, implant and prosthesis motility, and patient cosmetic satisfaction.
Purpose: To evaluate morphologic features and the evolution of inner retinal dimples using spectral domain optical coherence tomography after internal limiting membrane peeling.
Methods: A single-center retrospective study of spectral domain optical coherence tomography features in 43 eyes after full-thickness macular hole surgery with internal limiting membrane peeling without adjunctive internal limiting membrane staining.
Results: Postoperatively, a total of 210 dimples were noted in 37 eyes (86%), with a mean of 5.
Purpose: To evaluate the efficacy of intravitreal bevacizumab for prevention of macular edema after plaque radiotherapy of uveal melanoma.
Design: Retrospective, single-center, nonrandomized, interventional comparative study.
Participants: Patients with uveal melanoma treated with plaque radiotherapy were divided into 2 groups: a bevacizumab group and a control group.
Purpose: To evaluate the clinical features, treatment, and prognosis of patients with uveal metastasis from lung cancer.
Design: Retrospective chart review.
Participants: There were 194 patients with a diagnosis of uveal metastasis from lung cancer.
Purpose: To assess the overall risk of needlestick injuries (NSIs) associated with intravitreal injection, and more specifically related to the practice of compounding pharmacies of applying informational adhesive stickers to repackaged bevacizumab injection syringes.
Methods: This cross-sectional study involved an online survey of retina specialists in the United States.
Results: Of the 717 invited retina specialists, 158 (22%) responded to the online survey.
Objective: To evaluate the patient's understanding of the importance and adherence to the various lifestyle and Age-Related Eye Disease Study (AREDS) supplement recommendations for age-related macular degeneration (AMD).
Design: Cross-sectional study.
Participants: Patients with AMD treated at the vitreoretinal service clinic.
Optical coherence tomography (OCT) has revolutionized the field of ophthalmology since its introduction 20 years ago. Originally intended primarily for retina specialists to image the macula, it has found its role in other subspecialties that include glaucoma, cornea, and ocular oncology. In ocular oncology, OCT provides axial resolution to approximately 7 microns with cross-sectional images of the retina, delivering valuable information on the effects of intraocular tumors on the retinal architecture.

Design: Retrospective, comparative case series.
Participants: A total of 144 patients.
Purpose: To describe the outcome of intraocular tumor resection by partial lamellar sclerouvectomy (PLSU) in the pediatric age group.
Design: Retrospective, interventional case series.
Participants: We included 37 patients who underwent PLSU for intraocular tumors under age 21 years.
Purpose: To assess the efficacy of interferon alpha-2b (IFNα2b) in the management of ocular surface squamous neoplasia (OSSN).
Methods: This is a retrospective, nonrandomized interventional case series study of 80 patients with 81 tumors treated with IFNα2b eye drops and/or injection combined with surgical excision when necessary. The main outcome measure was complete response or partial response based on the American Joint Committee on Cancer classification.

Purpose Of Review: To review the literature for recent advancements in the femtosecond laser technology with regard to its applications in corneal transplantation and eye banking.
Recent Findings: Advancements in corneal surgery have encouraged the use of disease-specific corneal subcomponents, utilized in procedures such as anterior-lamellar keratoplasty and endothelial keratoplasty, instead of traditional transplant procedures to minimize adverse effects of penetrating keratoplasty. Femtosecond laser microkeratomes can precisely create flaps for such transplant procedures, achieve better wound stability, and promote healing by shaped wound configurations.
Purpose: To evaluate iris melanoma in children versus adults.
Methods: Retrospective, nonrandomized clinical case series including all patients with a clinical diagnosis of iris melanoma managed at the Ocular Oncology Service at Wills Eye Institute over 40 years. Patients were divided into three age categories based on age at presentation: children (≤ 20 years), mid-adults (21-60 years), and older adults (>60 years).
Objective: To evaluate the efficacy of interferon alpha-2b (IFNα2b) for extensive ocular surface squamous neoplasia (OSSN).
