Digital indocyanine green videoangiography has recently been reported to improve the imaging of occult choroidal neovascularization. In this study, 44 eyes with occult choroidal neovascularization in age-related macular degeneration were studied with fluorescein and indocyanine green videoangiography. On indocyanine green videoangiographic examination, 6 of the 44 eyes (13.6%) with occult choroidal neovascularization had vascularized pigment epithelial detachment and 27 (61.4%) had vascularized retinal pigment epithelium. In the remaining 11 (25%) eyes which had previous laser photocoagulation, indocyanine green videoangiography confirmed the presence of recurrence while fluorescein revealed no demonstrable neovascularization. The findings in our study indicate that patients with occult choroidal neovascularization have manifestations that are more clearly demonstrated with indocyanine green videoangiography and improved imaging of these abnormal vessels could potentially increase the number of patients eligible for photocoagulation treatment.

An update of multimodal imaging in white dot syndrome.
Oman J Ophthalmol

Department of Uvea, Sankara Nethralaya, Chennai, Tamil Nadu, India.
The white dot syndromes are a group of phenotypically similar disorders characterized by multiple lesions at the level of the outer retina, retinal pigment epithelium, and choroid. Common white dot syndromes whose imaging modalities have been described in this article are multiple evanescent white dot syndrome, acute posterior multifocal placoid pigment epitheliopathy, acute zonal occult outer retinopathy, multifocal choroiditis and panuveitis, punctate inner choroidopathy, serpiginous choroiditis, and birdshot chorioretinopathy. The various imaging modalities help us to better understand the pathophysiology of the various entities and help in diagnosing, monitoring, and prognosticating them.

To investigate long-term treatment outcomes of polypoidal choroidal vasculopathy (PCV) with classic type leakage and to compare the outcomes with those of PCV without classic type leakage. This retrospective study included 153 patients diagnosed with PCV and treated with anti-vascular endothelial growth factor (VEGF). Patients showing classic type leakage on fluorescein angiography were included in the classic type leakage group (N = 40, 26.

Article Synopsis
- Ocular siderosis (OS) can cause significant visual loss due to ferrous intraocular foreign bodies (IOFB), and timely diagnosis is critical for preventing severe impairment; magnetic resonance imaging (MRI) plays a key role when other imaging fails.
- A 51-year-old male experienced progressive vision loss in one eye, with initial imaging (CT and ultrasound) not revealing the IOFB, but MRI eventually identified it, leading to surgical intervention.
- The successful treatment restored the patient's vision to 20/20, reinforcing the need for awareness of OS in cases of unexplained vision loss from prior ocular trauma, even when standard imaging is inconclusive.
Elderly Patient With Bilateral Central Serous Chorioretinopathy Misdiagnosed as Bilateral Wet Age-Related Macular Degeneration: A Case Report.

Department of Ophthalmology, Amman Eye Clinic, Amman, JOR.
This report presents a unique case of a 77-year-old diabetic male patient with bilateral central serous chorioretinopathy (CSCR), who was receiving multiple bilateral intravitreal injections for a presumed diagnosis of wet age-related macular degeneration (AMD). The fundus examination did not show any signs of AMD or diabetic retinopathy (DR). The spectral domain optical coherence tomography (OCT) revealed bilateral subretinal fluid.
