PURPOSE OF REVIEW: Optical coherence tomography angiography (OCTA) is a novel, noninvasive imaging technique, which provides depth resolved visualization of microvasculature of the retina and choroid. Although OCTA has been widely used for the evaluation of a number of retinal diseases, its use in the field of neuro-ophthalmology has been less studied. In this review, we provide an update on the utility of OCTA in neuro-ophthalmic conditions. RECENT FINDINGS: Peripapillary and macular microvasculature analyses have indicated that OCTA can be a promising tool for early detection of a number of neuro-ophthalmic diseases, differential diagnosis, and monitoring of disease progression...

PURPOSE OF REVIEW: Although refractive surgery is one of the most commonly performed ophthalmic procedures, there is a relative paucity of literature on residency and fellowship refractive surgery education. The purpose of this article is to review the current state and recent updates to refractive surgery education and to evaluate the safety and visual outcomes of trainee performed refractive procedures. RECENT FINDINGS: Currently, there is no standard refractive surgery curriculum in the United States apart from required mandatory minimum refractive requirements for residents and fellows...

PURPOSE OF REVIEW: Currently, the most commonly performed corneal refractive surgery is laser-assisted in-situ keratomileusis (LASIK). Customized forms of LASIK have been developed, which have allowed for improved outcomes and the enhanced correction of higher order aberrations (HOAs). This review discusses one form of custom LASIK, topography-guided LASIK, including factors involved in preoperative planning, and advantages and disadvantages compared with other forms of keratorefractive surgery...

PURPOSE OF REVIEW: The aim of this study was to provide an update on perioperative considerations in the evaluation and management of patients undergoing primary corneal and intraocular refractive procedures who are at risk for progressive glaucomatous optic neuropathy. RECENT FINDINGS: The necessity of a comprehensive baseline assessment prior to refractive procedures with structural and functional testing, along with documentation of preoperative intraocular pressure (IOP) measurements, is highlighted in recent literature...

PURPOSE OF REVIEW: Age-related macular degeneration (AMD) is one of the leading causes of blindness and can progress to geographic atrophy (GA) in late stages of disease. This review article highlights recent literature which assists in the accurate and timely identification of GA, and monitoring of GA progression. RECENT FINDINGS: Technology for diagnosing and monitoring GA has made significant advances in recent years, particularly regarding the use of optical coherence tomography (OCT)...

PURPOSE OF REVIEW: To discuss antisense oligonucleotide (ASON) therapy for autosomal dominant retinitis pigmentosa (adRP) caused by the proline-23-histidine (P23H) mutation in the rhodopsin gene. RECENT FINDINGS: Viral and nonviral therapies to treat adRP are currently under investigation. A promising therapeutic option is a nonviral approach using ASONs. This form of genetic therapy has demonstrated a dose-dependent and highly selective reduction of P23H mutant rhodopsin mRNA in animal models, and it is currently being investigated as a human phase 1/2 clinical trial...

PURPOSE OF REVIEW: To summarize recent literature on Descemet's stripping only (DSO) in management of endothelial disease with particular focus on Fuchs endothelial corneal dystrophy (FECD). RECENT FINDINGS: DSO is currently indicated in patients with early FECD, central guttae, and preserved peripheral corneal endothelial cell (CEC) count. Time to corneal clearance may be accelerated and maintained with addition of topical rho-kinase inhibitor (ROCKi). There are reports describing successful use of DSO to treat endothelial disease due to iatrogenic trauma...

PURPOSE OF REVIEW: With limited access of more than half the world's population to corneal transplantation, regenerative medicine may represent a promising alternative. This review explores the main advancements achieved in cell-based therapies for corneal epithelium, stroma, and endothelium during 2021-2022. RECENT FINDINGS: Multiple surgical techniques have been developed for epithelial limbal stem cell replacement. Recent studies aimed to gain greater understanding and characterization of these techniques...

PURPOSE OF REVIEW: The purpose of this article is to provide a review of the literature on refractive lens exchange and present a retrospective analysis of 55 patients who underwent refractive lens exchange at a single practice. RECENT FINDINGS: Our study substantiates refractive lens exchange as an important option for presbyopic patients, hyperopic patients or patients with extremely high refractive error who desire spectacle independence. SUMMARY: Our study reveals that the refractive lens exchange population is younger than the average cataract population and their primary motivations are to resolve hyperopic or myopic refractive errors, gain spectacle independence, and address near vision loss...
