Purpose: To evaluate drusenoid retinal pigment epithelial detachments (DPED) secondary to age-related macular degeneration (AMD) using spectral-domain optical coherence tomography imaging.
Methods: In this prospective natural history study, eyes from patients with the diagnosis of nonexudative AMD and DPEDs were followed for at least 6 months. Eyes were scanned using the Cirrus spectral-domain optical coherence tomography instrument and the 200 × 200 A-scan raster pattern. A custom software was used to quantify volumetric changes in DPEDs and to detect the evolution and formation of geographic atrophy and choroidal neovascularization. Changes in DPED area and volume and development of the advanced forms of AMD were the main outcome.
Results: Of the 130 patients (186 eyes) with nonadvanced AMD, 11 patients (16 eyes) presented with DPEDs during the study. Mean follow-up was 18.5 months. Most DPEDs had an area exceeding 1 disk area (14 of 16 eyes) based on color fundus images with a mean area of 4.19 mm(2) (SD = 1.35) measured by spectral-domain optical coherence tomography. The mean volume at the time the DPED was diagnosed was 0.48 mm(3) (SD = 0.28). Four different patterns of progression were observed: DPEDs remained unchanged in 8 of 16 eyes (50%), DPEDs tended to increase in volume before progressing to geographic atrophy in 5 eyes (31.25%) and choroidal neovascularization in 2 eyes (12.5%), and a DPED decreased by more than 50% without progressing to geographic atrophy or choroidal neovascularization in 1 eye (6.25%).
Conclusion: Spectral-domain optical coherence tomography imaging is able to detect subtle changes in the area and volume of DPEDs. Quantitative spectral-domain optical coherence tomography imaging of DPEDs is useful for identifying the natural history of disease progression and as a clinical tool for monitoring eyes with AMD in clinical trials.

Acute zonal occult outer retinopathy (AZOOR) complex associated with torpedo retinopathy following COVID-19 recombinant mRNA vaccination: a case report of a rare clinical presentation.
BMC Ophthalmol
January 2025
Department of Ophthalmology, Linkou main branch, Chang Gung Memorial Hospital, Taoyuan, Taiwan.
Background: While vaccination remains crucial in mitigating the impact of the COVID-19 pandemic, several ocular adverse events has been reported, including Acute Zonal Occult Outer Retinopathy (AZOOR) complex.
Case Presentation: A 31-year-old female presented declined best corrected visual acuity (BCVA) and flashes in both eyes three days following second recombinant mRNA COVID-19 vaccine (Moderna). Fundus autofluorescence (FAF) illustrated speckled hyper-AF lesions surrounding right eye torpedo maculopathy site and hyper-AF lesions in the left macula.
Structural reversal of disc cupping measured in Bruch's membrane opening-based OCT morphometry after PRESERFLO microshunt implantation for open-angle glaucoma.
BMC Ophthalmol
January 2025
Department of Ophthalmology, Medical Faculty, University Hospital of Cologne, Kerpener Strasse 62, 50937, Cologne, Germany.
Background/ Aims: To analyze the longitudinal change in Bruch's membrane opening minimal rim width (BMO-MRW) and peripapillary retinal nerve fiber layer (pRNFL) thickness using optical coherence tomography (OCT) after implantation of a PRESERFLO® microshunt for surgical glaucoma management in adult glaucoma patients.
Methods: Retrospective data analysis of 59 eyes of 59 participants undergoing implantation of a PRESERFLO microshunt between 2019 and 2022 at a tertiary center for glaucoma management. Surgical management included primary temporary occlusion of the glaucoma shunt to prevent early hypotony.
Hardy-Rand-Rittler colour vision testing in cone and cone-rod dystrophies: correlation with structural and functional outcome measures.
Eye (Lond)
January 2025
Save Sight Institute, Faculty of Medicine and Health, The University of Sydney, Sydney, NSW, Australia.
Purpose: To determine how Hardy-Rand-Rittler (HRR) colour vision testing correlates with visual functional and structural assessments in Cone and Cone-Rod Dystrophy.
Methods: Thirty-four Cone and 69 Cone-Rod Dystrophy patients diagnosed by electroretinography (ERG) at the Save Sight Institute in Sydney were included in a retrospective analysis. Each patient's HRR colour vision test scores were compared with markers of cone and rod system function including visual acuity (VA), ERG responses, changes on Spectral Domain Optical Coherence Tomography (OCT) and Fundus Autofluorescence.
Multimodal imaging findings of the fellow eye in Stellate Nonhereditary Idiopathic Foveomacular Retinoschisis (SNIFR).
Retin Cases Brief Rep
January 2025
School of Medicine, Vita-Salute San Raffaele University, Milan, Italy.
Purpose: This study examines the multimodal imaging (MMI) findings in two cases of unilateral Stellate Nonhereditary Idiopathic Foveomacular Retinoschisis (SNIFR), including detailed findings from the unaffected fellow eye.
Methods: Macular spectral domain optical coherence tomography (OCT) and 3x3 mm optical coherence tomography angiography (OCTA), microperimetry, full-field electroretinography (ff-ERG) for both the affected and the fellow eye were reviewed.
Results: The MMI findings were consistent across the two cases (71-year-old female and 60-year-old female).
