Background: Diabetic macular edema (DME) is the main cause of visual loss in individuals with diabetic retinopathy (DR). This study aims to investigate the effects of central macular intraretinal cysts on the underlying outer retinal layer (ORL) in patients with diabetic macular edema (DME).
Methods: In this retrospective and cross-sectional study, diabetic patients with or without DR were categorized into three groups: without DME (group 1), with DME but without any cyst featuring a plateau in the lower region (group 2), and patients with cyst featuring an inferior cyst plateau (group 3), defined as a flat conformation at its posterior aspect.
Background: Acute retinal necrosis (ARN) is a progressive necrotizing retinitis caused by viral infection. Optimal management strategies have not been established for this detrimental disease. Previous literature published suggests that Varicella-zoster virus (VZV) and Herpes simplex virus-1 (HSV1) are the most common promoters of acute retinal necrosis (ARN).

Methods: Retrospective chart review of patients with MMP undergoing either fornix reconstruction (with amniotic membrane or buccal mucosal graft) or Wies cicatricial entropion repair between January 1, 2000, and September 1, 2020. Patients had a positive mucosal biopsy and (or) clinical features of MMP or secondary MMP.
Article Synopsis
- The concept of surgical futility involves complex discussions around when it is appropriate to provide or withdraw life-sustaining treatment for critically ill patients.
- Families may insist on aggressive treatments despite medical advice due to differing beliefs about quality and value of life.
- The manuscript outlines reasons for these disagreements, when doctors can ethically refuse futile treatments, and proposes guidelines for better communication during decision-making in these challenging situations.
Objective: To describe the long-term results of patients undergoing micropulse cyclophotocoagulation (MPCPC).
Methods: Retrospective review of patients undergoing MPCPC with 1 surgeon between July 2016 and January 2017. Data collected included preoperative intraocular pressure (IOP), number of medications, daily acetazolamide use, and whether inferior, superior, or circumferential MPCPC was performed.
Orbital metastases secondary to neuroendocrine tumors are exceedingly rare. We present a unique case of a 30-year-old female initially presenting with fever, chills, periorbital swelling, and painful proptosis. CT orbits revealed two ovoid-shaped ring-enhancing lesions in the right lateral and superior rectus muscles and clear sinuses, atypical for infectious post-septal cellulitis.

We sought to investigate and quantify retinal vascular changes in patients with MM vasculopathy (MMV) using optical coherence tomography angiography (OCTA) compared to healthy controls. Our findings reveal retinal microvascular changes in patients with MMV and highlights the potential of OCTA imaging for the detection of subclinical retinal pathology.

Methods: We enrolled 18 eyes of 9 healthy controls and 18 eyes of 9 patients with chronic SuS (12 had previous branch retinal artery occlusions and 6 were clinically unaffected). Images of the fovea were taken using an optical coherence tomography angiography system.
Objective: To investigate the quality of information related to glaucoma procedures found online using 2 different assessment tools.
Design: Cross-sectional survey of 100 web sites found via Google search engine.
Methods: The terms "peripheral iridotomy" and "trabeculectomy" along with synonymous keywords were inputted into Google's search engine.
