Abstract
This study aims to systematically review the reported literature on the use of anterior segment optical coherence tomography (AS-OCT) in ocular surface tumours and simulating lesions. A systematic literature search was done using PubMed, Scopus, and Web of Science databases between January 2002 and December 2021. On AS-OCT, ocular surface squamous neoplasia typically demonstrate epithelial thickening, epithelial hyperreflectivity, and an abrupt transition between normal and abnormal epithelium. Conjunctival nevi usually show mildly hyperreflective epithelium of normal thickness, internal hyperreflectivity, and intralesional cysts which is the hallmark of this tumour. Primary acquired melanosis presents with normal thickness epithelium, basal epithelial hyperreflectivity, and absence of cysts. Conjunctival melanoma demonstrates hyperreflective normal/thickened epithelium, hyperreflective basal epithelium, internal hyperreflectivity, and absence of intralesional cysts. Conjunctival lymphoma shows homogenous, low-medium reflective subepithelial lesions with smooth borders, and dot-like infiltrates. Benign reactive lymphoid hyperplasia findings are similar to lymphoma but the infiltrates are more hyperreflective compared to lymphoma. Pterygium shows thickened conjunctival epithelium, epithelial hyperreflectivity, and subepithelial wedge-shaped hyperreflective tissue separated from the overlying epithelium by a cleavage plane. Pinguecula demonstrates mildly thickened epithelium and similar findings with pterygium but does not extend beyond the corneal limbus. This review shows that AS-OCT, as a noninvasive tool, has potential uses in the differential diagnosis of ocular surface tumours and simulating lesions. Major limitations of AS-OCT include limited visualization of the posterior border of thick, keratinized, and pigmented tumours and lack of assessment of large conjunctival tumours in a single cut.

Abstract
PURPOSE The aim of this study was to determine the ophthalmologic involvement in patients with hereditary transthyretin amyloidosis and its correlation with the mutations described in the literature. METHODS Cross-sectional, noninterventional study. Fifty-two eyes of 26 consecutive patients diagnosed with hereditary transthyretin amyloidosis who visited the Puerta de Hierro-Majadahonda University Hospital from September 2019 to March 2022. All patients underwent complete ophthalmologic examination and multimodal imaging. Cardiologic, neurologic, digestive, and renal examinations were also recorded. RESULTS Eighteen eyes of the total (34.61%) showed amyloid-related ocular involvement, vitreous amyloid deposits being the most common ocular manifestation (18/52). Statistically significant differences were found for the presence of vitreous amyloid deposits ( P < 0.01), crystalline amyloid deposits ( P < 0.05), parenchymal amyloid deposits ( P < 0.01), and vascular alterations ( P < 0.01) when comparing affected and unaffected eyes. Moreover, affected eyes showed worse best-corrected visual acuity ( P < 0.01). CONCLUSION Ocular manifestations are present in a substantial number of patients with ATTR that could potentially lead to devastating consequences to patients' best-corrected visual acuity and quality of life. Therefore, it is important to emphasize the importance of multidisciplinary management and ophthalmologic assessment, follow-up and surgical treatment when necessary. To the best of our knowledge, this represents the largest series in Spain of amyloidosis' ophthalmologic involvement.

Abstract
Retinal angiopathy associated with hereditary transthyretin amyloidosis (ATTRv), if untreated, may lead to irreversible vision loss. Our purpose was to systematically review the clinical and imaging features of retinal angiopathy associated with ATTRv and assemble a monitoring approach for these patients. All types of original research studies reporting clinical and imaging findings on retinal angiopathy associated with ATTRv were included. The most common clinical findings were tortuous retinal vessels, microaneurysms, retinal hemorrhages, sheathing of retinal vessels, whitish amyloid deposits along retinal arteries, obliteration of retinal vessels, vitreous hemorrhage, retinal and iris neovascularization. The most relevant imaging findings were hyperautofluorescence of perivessel amyloid deposits; delayed arterial filling, vascular leakage, and retinal ischemia on fluorescein angiography; late hypercyanescence along the choroidal arteries on indocyanine green angiography; perivascular hyperreflective material, needle-shaped deposits on the retinal surface and macular edema on optical coherence tomography (OCT) and attenuated retinal vascular network on OCT-angiography. ATTRv patients should be strictly followed to detect and treat retinal angiopathy, avoiding complications. Both panretinal photocoagulation and intravitreal anti-vascular endothelial growth factor have been used to treat retinal angiopathy in ATTRv. In an individual that presents with retinal angiopathy of unknown etiology, ATTRv should be considered as in the differential diagnosis, even out of the initial core countries. The prognostic value of subclinical findings, namely in OCT-A, is not yet established.

Abstract
Background Hereditary transthyretin amyloidosis (ATTR amyloidosis) is a rare condition where a mutation in the transthyretin gene leads to systemic deposition of amyloid. The manifestations and prognosis of ATTR amyloidosis depends on the specific ATTR mutation, with over 100 mutations reported in the literature. The manifestations of many rare forms of ATTR amyloidosis have not been well described, particularly the late-onset ophthalmic findings. Case presentation We present the case of a 43-year-old Caucasian male with a diagnosis of ATTRD18E amyloidosis confirmed by fat pad biopsy. He had diffuse systemic involvement, including cardiovascular, pulmonary, and gastrointestinal symptoms. He also had significant ocular involvement including vitreous opacities, retinal angiopathy, and conjunctival lymphangiectasia. These ocular findings modestly progressed at 2-year follow-up. Discussion The ATTRD18E mutation is a rare variant, with few described cases. To our knowledge, this is the first documented case of ATTRD18E amyloidosis with significant ocular involvement. These ocular findings may serve as a relevant biomarker for severe disease prognosis in ATTRD18E amyloidosis. With improving treatments addressing the systemic symptoms of ATTR amyloidosis, a better understanding of the late-onset ocular symptoms is becoming increasingly relevant.

Abstract
The term amyloidosis describes a group of rare diseases caused by protein conformation abnormalities resulting in extracellular deposition and accumulation of insoluble fibrillar aggregates. So far, 36 amyloid precursor proteins have been identified, and each one is responsible for a specific disease entity. Transthyretin amyloidosis (ATTRv) is one of the most common forms of systemic and ocular amyloidosis, due to the deposition of transthyretin (TTR), which is a transport protein mainly synthesized in the liver but also in the retinal pigment epithelial cells. ATTRv amyloidosis may be misdiagnosed with several other conditions, resulting in a significant diagnostic delay. Gelsolin and keratoepithelin are other proteins that, when mutated, are responsible for a systemic amyloid disease with significant ocular manifestations that not infrequently appear before systemic involvement. The main signs of ocular amyloid deposition are in the cornea, irido-corneal angle and vitreous, causing complications related to vasculopathy and neuropathy at the local level. This review aims at describing the main biochemical, histopathological and clinical features of systemic amyloidosis associated with eye involvement, with particular emphasis on the inherited forms. We discuss currently available treatments, focusing on ocular involvement and specific ophthalmologic management and highlighting the importance of a prompt treatment for the potential sight-threatening complications derived from amyloid deposition in ocular tissues.

Abstract
PURPOSE To investigate the tomographic features in patients with hereditary amyloidosis transthyretin (hATTR). DESIGN Retrospective case series and analysis of B-scan OCT images. PARTICIPANTS A total of 120 patients (240 eyes) diagnosed with hATTR. METHODS We performed a retrospective review of the treatment history and retrospective analysis of the OCT images of patients with hATTR. The parameters analyzed were the age at which the last OCT was performed, presence of ocular amyloidosis, history of pars plana vitrectomy (PPV), systemic treatment, and genetic mutations. Two independent evaluators evaluated the OCT images for characteristic needle-shaped pattern deposits on the retinal surface, and a third evaluator resolved any differences in their evaluations. MAIN OUTCOME MEASURES The frequency of characteristic needle-shaped deposits on the retinal surface seen on OCT. RESULTS The mean age at the time of the last OCT was 56.5 ± 14.9 years. Ninety-nine patients had gene encoding transthyretin (TTR) with the Val30Met mutation, and 21 patients had other mutations. Of 240 eyes, 128 had signs of ocular amyloidosis. Fifty of 73 eyes (68.5%) with a history of PPV for vitreous opacities exhibited characteristic deposits on OCT. Four of 31 eyes with vitreous opacity but without a history of PPV showed deposits on the retinal surface. No eyes without a history of vitreous opacities revealed the characteristic needle-shaped deposits. CONCLUSIONS Characteristic needle-shaped deposits on the retinal surface seen on OCT are significant because they are seen in most of the vitrectomized eyes presenting with ocular amyloidosis.
