Survey of Ophthalmology

Neurotrophic keratopathy is an uncommon degenerative corneal disorder characterized by compromised corneal sensory innervation, resulting in the formation of epithelial defects and nonhealing corneal ulcers. Various treatment modalities are available to stabilize disease progression, improve patient well-being, and prevent vision loss. For eligible patients, medical and surgical reinnervation have emerged as pioneering therapies, holding promise for better management. This article presents a comprehensive review of the disease, providing an update relevant to ophthalmologists on pathogenesis, diagnosis, treatment options, and novel therapies targeting pathophysiological pathways...

Macular holes (MH) are full-thickness retinal defects affecting central vision. While vitrectomy with inner limiting membrane (ILM) peel is the conventional MH treatment, non-surgical alternatives are gaining interest to mitigate surgical risks. This study conducted a comprehensive literature review and analysis of non-surgical MH management. A systematic literature search was conducted on PubMed, Embase, Scopus, and the Cochrane Library from January 1, 1973, to September 13, 2023. Treatments included laser therapy, carbonic anhydrase inhibitors (CAIs), non-steroidal anti-inflammatories (NSAIDs), steroids (topical, subtenons, peribulbar, intravitreal), intravitreal gas, anti-vascular endothelial growth factors (VEGF) and ocriplasmin injections...

We assess risk factors for complications associated with resident-performed cataract surgery. Using the Preferred Reporting Items for Systematic reviews and Meta-Analyses guidelines, we searched 4databases in September, 2023. We included peer-reviewed, full-text, English-language articles assessing risk factors for complications in resident performed cataract surgery. We excluded studies describing cataract surgeries performed by fellows, combined surgeries, and studies with insufficient information. Our initial search yielded 6244 articles; 15 articles were included after title/abstract and full-text review...

BACKGROUND: In recent years, the progress made in the field of optical coherence tomography (OCT) has helped to understand the changes in eye layers in patients with exudative age-related macular degeneration (AMD). Early diagnosis of AMD as a leading cause of irreversible vision impairment is helpful. Therefore, we aim to perform a meta-analysis on OCT measurement alterations before and after anti-VEGF therapy in patients with AMD and controls. METHOD: We systematically searched Scopus, PubMed, Cochrane, and Web of Science to find articles that measured choroidal and retinal layer changes after anti-VEGF therapy in AMD Patients...

Corneal epithelial defects are one of the most common ocular disorders.Restoring corneal integrity is crucial to reduce pain and regain function,but in cases of neurotrophic or desensitized corneas,healing can be significantly delayed.Treating neurotrophic corneas is challenging for ophthalmologists,and surgical intervention is often indicated to manage refractory cases that are unresponsive to medical therapy.Over the last decade,as more expensive therapeutics reach the market,topical insulin has returned to the forefront as an affordable option to improve corneal wound healing...

The standard of care to treat small- and medium-sized macular holes (<400μm diameter) consists of a conventional transconjunctival sutureless pars plana vitrectomy followed by ILM peeling and endotamponade, mainly with gas or in some cases with silicone oil, resulting in closure rates of over 90% and good functional results. Large (>400μm diameter), chronic and persistent macular holes remain a surgical challenge since closure rates and functional results decrease with larger macular hole diameters...

Diabetic retinopathy (DR) is characterized by retinal vasculopathy and is a leading cause of visual impairment. Optical coherence tomography angiography (OCTA) is an innovative imaging technology that can detect various pathologies and quantifiable changes in retinal microvasculature. We briefly describe its functional principles and advantages over fluorescein angiography and perform a comprehensive review on its clinical applications in the screening or management of people with prediabetes, diabetes without clinical retinopathy (NDR), nonproliferative DR (NPDR), proliferative DR (PDR), and diabetic macular edema (DME)...

The development of intravitreally injected biologic medicines (biologics) acting against vascular endothelial growth factor (VEGF) substantially improved the clinical outcomes of patients with common VEGF-driven retinal diseases. The relatively high cost of branded agents, however, represents a financial burden for most healthcare systems and patients, likely resulting in impaired access to treatment and poorer clinical outcomes for some patients. Biosimilar medicines (biosimilars) are clinically equivalent, potentially economic alternatives to reference products...

Age-related macular degeneration (AMD) is the most common cause of irreversible visual impairment among people aged 50 years and older. Earlier research has indicated that the communication process between patients and healthcare professionals (HCPs) leaves considerable room for improvement in AMD care. Effective communication is essential to enhance trust in the professional and understanding of the diagnosis and treatment, and decrease anxiety and stress related to illness. We review patients' experiences, needs and preferences regarding information provision, communication style of the HCP and shared decision-making...

Artificial Intelligence (AI) has become a focus of research in the rapidly evolving field of ophthalmology. Nevertheless, there is a lack of systematic studies on the health economics of AI in this field. We examine studies from the PubMed, Google Scholar, and Web of Science databases that employed quantitative analysis, retrieved up to July 2023. Most of the studies indicate that AI leads to cost savings and improved efficiency in ophthalmology. On the other hand, some studies suggest that using AI in healthcare may raise costs for patients, especially when taking into account factors such as labor costs, infrastructure, and patient adherence...

Proliferative vitreoretinopathy (PVR) is an abnormal and prolonged healing response to retinal injury (retinal detachment, post retinal detachment surgery) characterised by: pre/subretinal membrane formation; retinal gliosis and retinal shortening, retinal pigment epithelium cell proliferation; and increased glial (mainly Mu¨ller cells), fibroblast and inflammatory cell (macrophage, lymphocyte) activity, leading to tractional retinal holes/breaks and multiple costly eye operations suffered by patients...

Post-operative cystoid macular edema (PCME) is an important complication following intraocular surgery that often resolves spontaneously without treatment. In some cases, PCME may persist despite initial medical therapy, which can adversely impact visual outcomes. Various topical, intraocular and systemic treatments exist for the prevention and management of cystoid macular edema; however, there is no consensus on treatment of refractory cases in the postoperative setting. In accordance with the PRISMA guidelines, we systematically reviewed 68 articles describing management options and their outcomes for treatment-resistant cases of PCME...

A 60-year-old man presented to an outside ophthalmology clinic with 1 month of progressive vision loss in the right eye (OD). Right optic disc edema was noted. Brain and orbit magnetic resonance imaging revealed right optic nerve and left occipital lobe enhancement. He was seen initially by neurology and neurosurgery and subsequently referred to neuro-ophthalmology for consideration of optic nerve biopsy. He was seen 3 months after his initial symptom onset where vision was light perception OD and a relative afferent pupillary defect with optic nerve edema...

We performed a comprehensive systematic review to identify medication-associated orbital inflammation and to characterize its clinico-radiological features. We reviewed English-language articles describing medication-associated orbital inflammation (i.e., orbital myositis, dacryoadenitis and orbital fat) published to June 2023. Isolated inflammation of the intraocular structures or globe alone (i.e. uveitis), scleritis, optic neuritis and peri-neuritis) were excluded. In medication-associated orbital inflammation, the extraocular muscles are preferentially affected, occurring in isolation or in combination with other orbital and/or intraocular structures...

Traditionally, clinical outcome assessments have focused on the patient's perspective through patient-reported outcome assessments; however, given the complexity, integration, and interactions of various participants within the clinical ophthalmology setting, we propose that additional diverse clinical perspectives should be explored in order to fully appreciate the value of care provided to patients. In this review we introduce a framework by which clinical outcome assessments (COAs) can be organized. Our COA framework is composed of five outcome measurements that encompass the perspectives of each player in a patient's care: clinical data-reported outcomes, patient-reported outcomes, clinician-reported outcomes, observer-reported outcomes, and reviewer-reported outcomes...

Laser photocoagulation (LPC) and/or intravitreal anti-vascular endothelial growth factor (anti-VEGF) injections constitute the current standard treatment for retinopathy of prematurity (ROP). This network meta-analysis focus on whether a ranking of interventions may be established for different dose levels of intravitreal injection of anti-VEGF agents (aflibercept, bevacizumab, conbercept, ranibizumab) as primary treatments for ROP versus laser in terms of retreatment rate as primary outcome, and time to retreatment and refractive error as secondary endpoints, since best anti-VEGF dosage remains under debate...

Diabetic retinopathy (DR) is one of the common microvascular complications of diabetes mellitus and is the main cause of visual impairment in diabetic patients. The pathogenesis of DR is still unclear. The complement system, as an important component of the innate immune system, in addition to defending against the invasion of foreign microorganisms, is involved in the occurrence and development of DR through 3 widely recognized complement activation pathways, the complement regulatory system, and many other pathways...

We aim to provide a detailed and updated literature review on the epidemiology, etiology, clinical presentations, histopathology, and ultrastructural features of punctal stenosis. There are inconsistencies in the definition and staging of punctal stenosis. While advanced optical coherence tomography imaging techniques have revolutionized the way the punctum and vertical canaliculi are assessed or monitored following treatment, the planes of measurement to characterize punctum anatomy need to evolve further...
