We report the first two cases of postoperative opacification scleral-sutured Akreos AO60 intraocular lens after vitrectomy with gas tamponade.Two patients ectopia lentis underwent pars plana vitrectomy, lensectomy, and scleral fixation an Gore-Tex suture. Retinal breaks were noted during consequently intravitreal tamponade was used endolaser retinopexy. Postoperatively, both developed but maintained excellent visual acuity; however, one patient bothersome though tolerable...
To present a novel case of immune retinopathy associated with nivolumab therapy for non-small cell lung cancer.Retrospective chart review.A 64-year-old woman presented photoreceptor injury evidenced by hypoautofluorescent and hyperautofluorescent patches on fundus autofluorescence, loss the ellipsoid zone optical coherence tomography, dysfunction rods cones electroretinogram. She had history Stage IV adenocarcinoma, treated nivolumab, checkpoint inhibitor. Serology testing was negative...
The human eye’s intricate anatomical and physiological design necessitates tailored approaches for managing ocular diseases. Recent advancements in ophthalmology underscore the potential of hydrogels as a versatile therapeutic tool, owing to their biocompatibility, adaptability, customizability. This review offers an exploration hydrogel applications over past five years. Emphasis is placed on role optimized drug delivery posterior segment intraocular lens technology. Hydrogels demonstrate...
ABSTRACT Retinal degenerative diseases affect millions of people worldwide, and legal blindness is generally associated with the loss cone photoreceptors located in central region retina called macula. Currently, there no treatment to replace Addressing this unmet need, we employed control isogenic hypoimmunogenic induced pluripotent stem cell lines generate spontaneously polarized retinal sheets (RSs). RSs were enriched progenitor precursor cells, which could differentiate into mature S-...
Paracentral acute middle maculopathy (PAMM) is a recently identified clinical entity with numerous retinal vascular and systemic associations. To our knowledge, this the first reported case of PAMM associated idiopathic intracranial hypertension.A presented multimodal imaging.A patient hypertension found to have characteristic clinical, spectral domain optical coherence tomography, OCT angiography findings PAMM.Paracentral believed arise from microvascular insult deep capillary plexus. We...

Diffuse unilateral subacute neuroretinitis (DUSN) is often a challenging diagnosis to make. We present DUSN case with its multimodal imaging aid in the diagnosis, emphasizing observations on optical coherence tomography angiography (OCTA). The evolution of presented. Fundus photography and OCTA aided identification nematode. difficult establish. report first our knowledge which DUSN.
Abstract Background To evaluate laser-assisted in situ keratomileusis (LASIK) outcomes, subjective quality of vision (QoV) and patient satisfaction eyes with very high myopia (VHM) above − 10.00 diopters (D). Methods Consecutive myopic myopic-astigmatism spherical equivalent (SEQ) ranging between to 13.50 D underwent LASIK the WaveLight® Allegretto Wave® Eye-Q 400 Hz excimer laser. Treatment accuracy, efficacy, safety, stability, cylinder vectors, higher-order aberrations were evaluated,...
Purpose: To report the multimodal imaging and enlargement of sclerochoroidal calcifications over a 10-year period. Methods: Case 74-year-old white man who presented for routine follow-up was found to have yellow chorioretinal lesions in right eye. Results: Multimodal performed confirmed calcifications. Comparison fundus photography period demonstrated growth preexisting development new Conclusion: Over time, this patient developed We, therefore, recommend regular with periodic these patients.
To describe a technique of combined scleral buckle with external needle drainage and vitrectomy in the treatment bullous exudative retinal detachment, schisis or retinoschisis threatening fovea.A retrospective chart review four eyes patients who underwent procedure described.Four buckling by single surgeon for fovea were included this series. All attached after surgical intervention. No patient developed complications from drainage.External subretinal intraschisis fluid combination is...
Prosthetic iris devices have recently been used to improve cosmesis and reduce glare in aniridia. There is currently no consensus on which prosthetic device or surgical approach preferred for managing large defects.A novel with Gore-Tex polytetrafluoroethylene sutures was achieve scleral fixation of an intraocular lens artificial complex a 19-year-old Caucasian female patient aniridia, nystagmus, cataracts, ectopia lentis.Six weeks postoperatively, the lens-artificial remained well centered,...
To describe a case of an isolated Group 3 retinal arteriovenous malformation (AVM).Observational report.A 15-year-old girl with no significant medical history presented light perception vision in her right eye and gradually decreasing left over several years. She was found to have large AVM the posterior pole associated perivascular sheathing periphery. Her seemed totally unremarkable. Neuroimaging revealed intracranial or intraorbital abnormalities. A diagnosis made.Retinal AVMs are...
Background: Autosomal recessive bestrophinopathy is part of the diverse spectrum retinal diseases caused by mutations in BEST1 gene. Methods: A case report. Results: We present a that highlights classic findings autosomal with an emphasis on modern multimodal imaging. Conclusion: describe imaging individual gene mutation and clinical consistent bestrophinopathy.
Purpose: To describe three patients with idiopathic multifocal choroiditis (MFC) who showed foci of foveal outer retinal hyperreflectivity on optical coherence tomography. Methods: Retrospective review electronic health records and multimodal imaging from MFC. Results: Three consecutive white MFC (two male one female) presented unilateral in the eye active In all cases, lesions persisted for at least 1 month. Optical tomography demonstrated finger-like projections extending pigment...
To report the association of rubeosis iridis with chronic bullous degenerative peripheral retinoschisis. A 63-year-old female presented acute hyphema and neovascularization iris in elevated intraocular pressure. Posterior segment examination including imaging revealed no vascular occlusion as a potential cause. However, large, retinoschisis was noted right eye. No nonperfusion aside from that seen within schism detachment, or retina on wide-field fundus photography fluorescein angiography...
To describe a patient with confirmed transthyretin V30M form of familial amyloidosis who presented initially isolated retinal angiopathy.Retrospective chart review.A 66-year-old woman bilateral angiopathy. Extensive workup for an infectious, inflammatory, or hypercoagulable cause was unrevealing. The subsequently developed neovascularization the optic nerve and iris complicated by recurrent vitreous hemorrhages, which were treated intravitreal bevacizumab panretinal photocoagulation....
Purpose: This study examines treatment-based outcomes of endophthalmitis due to antivascular endothelial growth factor (anti-VEGF) intravitreal injection and its effect on subsequent management neovascular disease. Methods: A retrospective multicenter was conducted 157 patients with a diagnosis following anti-VEGF at 10 major ophthalmic centers. Results: The median number injections before (range, 1 84 injections). Initial treatment tap inject or without vitrectomy trended toward smaller...

Multimodal imaging[1] is increasingly used for clinical diagnosis and an increased pathophysiological understanding of retinal disease.[1] Recently, MultiColor scanning laser ophthalmoscopy has been incorporated into the Spectralis platform (Heidelberg Engineering, Heidelberg, Germany). This system uses wavelengths blue, green, infrared simultaneously to provide information superficial, middle, deeper structures, respectively, a single image.[2] We continue learn new artifacts associated...
