PURPOSE: To identify optical coherence tomography (OCT) findings associated with the leakage points in patients with central serous chorioretinopathy (CSC) to provide fluorescein angiography (FA)-free focal laser photocoagulation (FLP) of the leakage point. METHODS: A retrospective study included 48 patients with CSC (48 eyes). Colocalisation of leakage points with pigment epithelial detachments (PEDs) and with areas of photoreceptor outer segments (PROS) layer thinning was evaluated with OCT...

Purpose: To present ophthalmic imaging findings in the case of a 40-year-old male with sustained visual loss after a single episode of acute central serous retinopathy (CSR). Observations: A male subject presented with visual acuity decline to 20/50 OS and was diagnosed with acute CSR. The initial pigment epithelial detachment and subretinal fluid resolved within 6 weeks, but visual acuity remained impaired. Using directional optical coherence tomography (D-OCT) and confocal and split-detector adaptive optics scanning light ophthalmoscopy (AOSLO), we imaged pathologic alterations in the photoreceptor mosaic of the affected eye...

Purpose: The purpose of this study is to analyze early retinal angiomatous proliferation (RAP) utilizing a novel imaging modality, Projection-Resolved Optical Coherence Tomography Angiography (PR-OCTA). Observations: Five months prior to the diagnosis of a RAP lesion, cross-sectional PR-OCTA demonstrated flow in the outer retina contiguous with the deep retinal capillary plexus (DCP) and adjacent to a small pigment epithelial detachment. After development of a clinically visible RAP lesion, cross-sectional PR-OCTA demonstrated the RAP lesion connecting DCP and sub-retinal pigment epithelial neovascularization...

BACKGROUND/PURPOSE: To report a case of cuticular drusen in an indigenous Australian. METHODS: A 37-year-old indigenous (aboriginal) Australian woman from a remote Western Australian town presented with a 2-month history of vision loss. Clinical history, examination, and multimodal retinal imaging data from spectral domain optical coherence tomography, fundus autofluorescence, fluorescein angiography, and indocyanine green angiography were analyzed. RESULTS: Multimodal imaging confirmed cuticular drusen complicated by a right choroidal neovascularization with pigment epithelial detachment and a left foveal vitelliform lesion...

BACKGROUND: To investigate whether genetic risk variants for age-related macular degeneration (AMD) are associated with response to intravitreal anti-vascular endothelial growth factor (VEGF) in polypoidal choroidal vasculopathy (PCV) patients. METHODS: This prospective cohort study included 95 treatment-naïve patients that underwent anti-VEGF treatment for PCV for 12 months. Patients were genotyped for 10 single nucleotide polymorphisms in eight AMD-relevant genes...

PURPOSE: To analyze the efficacy of aflibercept switch treatment for regression of pigment epithelial detachment (PED) in patients previously treated with ranibizumab. METHODS: Multicenter, prospective, nonrandomized clinical trial. One eye of patients presenting neovascular age-related macular degeneration with PED of more than 250 μm in height, with persistent fluid, was included.

PURPOSE: Failure of retinal detachment surgery is most commonly due to the development of proliferative vitreoretinopathy (PVR). Everolimus is an inhibitor of mammalian target of rapamycin (mTOR), and is available as oral tablets. In this study, we investigated the effect of everolimus on retinal pigment epithelial cells and modification of the severity of experimental PVR. METHODS: In our in vitro studies, primary culture of retinal pigment epithelium (RPE) cells was obtained from pigmented Rex rabbits...

BACKGROUND: To describe the optical coherence tomography angiograhy (OCTA) of drusenoid pigment epithelial detachments (PEDs) in a woman affected by Complement 3 (C3) glomerulopathy, which represents a spectrum of glomerular diseases characterized on fluorescent microscopy by C3 accumulation with absent, or scanty, immunoglobulin deposits. It is due to acquired or genetically defective alternative pathway control and is generally associated with drusen-like deposits in Bruch's membrane, as well as choriocapillaris...

PURPOSE: To investigate the outcomes of intravitreal aflibercept in refractory pigment epithelial detachment (PED) with or without subretinal fluid (SRF) in patients with neovascular age-related macular degeneration. METHODS: A prospective, nonrandomized, interventional case series involved 40 patients with persistent vascularized PED previously treated with at least 3 injections of intravitreal bevacizumab or ranibizumab. Intravitreal aflibercept was administered as 3 initial loading doses every 4 weeks, followed by pro re nata retreatment every 8 weeks over 48 weeks...

PURPOSE: To describe the features of peripapillary pachychoroid syndrome (PPS), a novel pachychoroid disease spectrum (PDS) entity. METHODS: Medical records of 31 eyes (16 patients) with choroidal thickening associated with intraretinal and/or subretinal fluid in the nasal macula extending from the disk were reviewed (patients with PPS). Choroidal thickness was compared with 2 age-matched cohorts: typical PDS (17 eyes with central serous chorioretinopathy or pachychoroid neovasculopathy) and 19 normal eyes...

Proliferative vitreoretinopathy (PVR) is a disease caused by de-differentiation, translocation and proliferation of several types of local cells. These cells form fibrocellular membranes resulting in detachment of retinal and vision loss. PVR occurs in 8%-10% of patients undergoing primary retinal detachment (RD) surgery and becomes a major obstacle for successful RD repair. Retinal pigment epithelial (RPE) cells are among the major cells which consist of fibrocellular membranes. Re-proliferation and Epithelial-mesenchymal transition (EMT) are the primary pathological alteration of RPE cells in PVR...

BACKGROUND: A 70-year-old woman with retinitis pigmentosa experienced an epiretinal membrane (ERM) formation and a tractional retinal detachment (RD) following subretinal administration of palucorcel (CNTO 2476), a novel human umbilical tissue-derived cell-based therapy, as part of a Phase I study. The clinical course and results of a histologic examination of the ERM, which was peeled during surgery to repair the RD, are described here. METHODS: In this open-label, first-in-human, Phase I study (NCT00458575), two of seven subjects developed RD, with an ERM formation reported in a woman receiving a targeted dose of 3...

Patrick Oellers, Dean Eliott
Persistent subretinal fluid (SRF) can impair visual recovery after vitrectomy or scleral buckling surgery for rhegmatogenous retinal detachment. Several hypotheses have been proposed for delayed absorption of SRF, but the etiology has not been clearly identified. The authors present a patient with persistent SRF after vitrectomy for retinal detachment who developed central serous chorioretinopathy (CSCR) during the postoperative period in the nonoperative eye. Thus, subclinical retinal pigment epithelial (RPE) dysfunction was likely present in the operative eye, and when overloaded with SRF after retinal detachment repair, this manifested as delayed absorption...

The authors report on two patients with bilateral acute exudative polymorphous paraneoplastic vitelliform maculopathy (AEPPVM) treated with intravitreal aflibercept (Eylea; Regeneron, Tarrytown, NY [marketed locally in Turkey by Bayer]). Underlying malignancy had been treated in each case, including breast carcinoma in one case and colon carcinoma in the other case. A macular vitelliform lesion was noted in the right eye and atrophic retinal pigment epithelial (RPE) changes were noted in the left eye of each case...

PURPOSE: To describe cases presenting with features of idiopathic macular telangiectasia (MacTel) Type 2 and central serous chorioretinopathy (CSC). METHODS: Databases from four tertiary retina centers were searched for cases copresenting CSC and MacTel Type 2. RESULTS: Five cases were identified (4 men, 1 woman; mean age: 67.2 years). Four patients were referred for chronic or nonresolving CSC, and the diagnosis of MacTel Type 2 was made based on multimodal imaging findings...
