Herein, we describe the varied clinical course and management of three patients with retinal focal nodular gliosis, one of whom is associated with retinitis pigmentosa.\u0000Observations: Case 1 is a 76-year-old female who presented with reduced vision and distortion secondary to a vitreous hemorrhage and epiretinal membrane (ERM) as complications of a known small peripheral retinal focal nodular gliosis. She underwent vitrectomy for the hemorrhage to relieve vascular traction and the ERM peel and the tumor was kept under observation. Case 2 is a 24-year-old female with genetically uncharacterized retinitis pigmentosa-like phenotype who presented with gradual loss of central vision in one eye due to cystoid macular oedema (CMO). She was found to have two peripheral retinal areas of focal nodular gliosis located inferonasally. Tumors were treated with cryotherapy and adjuvant intraocular steroid implant to control the CMO. Case 3 is a 28-year-old female with retinitis pigmentosa secondary to genetically confirmed variant in CRB1 gene who presented with intractable right eye cystoid macular oedema and localized inferior serous retinal detachment secondary to a large inferotemporal focal nodular gliosis. Her left eye has no light perception vision due to previous extensive serous retinal detachment and anterior segment ischemia. The right eye tumor was managed with multiple rounds of cryotherapy and laser therapy to control the serous detachment. Despite this, the condition progressed and was ultimately treated with plaque brachytherapy. Unfortunately, this resulted in an extensive retinal inflammation causing annular tractional retinal detachment which was treated with combined pars plana vitrectomy and scleral buckle.\u0000Conclusions: We characterized the retinal phenotype of three patients with retinal focal nodular gliosis (vasoproliferative tumors) and found them to have varied clinical courses requiring tailored surgical management. The case associated with retinitis pigmentosa had a known pathogenic variant in Crumbs homolog-1 (CRB1) gene affecting retinal structure and exhibited a more severe clinical course. It is therefore important for patients with retinal dystrophies to undergo thorough peripheral examinations and detect FNG early as they may require prompt, aggressive treatment.\u0000","PeriodicalId":19434,"journal":{"name":"Ocular Oncology and Pathology","volume":null,"pages":null},"PeriodicalIF":1.0,"publicationDate":"2024-05-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141120166","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

A total of 886 patients were diagnosed and treated for primary choroidal melanoma between November 2017 and June 2023 at St. Paul's Eye Unit, Royal Liverpool University Hospital, UK. The fundus photographs were screened for lipid exudates by two independent clinical experts. The patients’ demographics, clinical manifestations and imaging features were analysed, whereas the location of exudation was documented with fundus photographs and optical coherence tomography (OCT). The histopathological and genetic results were also analysed in cases with tumour biopsy available.\u0000Case Presentations: Eight cases with subretinal exudates were identified (n=8/886, 0.90%). No gender predilection was noticed (male/female 1:1), whereas the mean age was 51 years (range 39-79). Four patients were asymptomatic at presentation, two patients reported reduced visual acuity, and two patients presented with photopsia. OCT scans revealed the presence of subretinal fluid and subretinal exudates, while the ultrasound showed medium or low internal reflectivity in 7 out of 8 cases.

Visual acuity (VA) deterioration to ≤6/60 is common. We report a pilot study of reduced-dose SRT using 2 Gy/day, aiming to preserve vision without compromising survival. Method: 60 Gy SRT was delivered in 30 fractions over 6 weeks. Liver metastasis surveillance was annual ultrasound. The primary endpoint was 5-year metastasis-free survival (5yMFS). Secondary endpoints were 2-year freedom from local progression (2yFFLP), VA, enucleation rate, and radiation toxicity. Results: Twenty adults aged ≤70 years with T1-T2M0 CM without diabetes mellitus were enrolled. Median follow-up was 5.1 years. About 85% and 90% of tumours were ≤3 mm of the macula and optic disc, respectively. Median tumour height was 2.2 mm (range 1.0–4.4 mm), and median basal diameter was 8.2 mm (range: 4.3–15.0 mm). 5yMFS was 88% (95% CI: 61–97), and the 2yFFLP rate was 90% (95%: CI 66–97). There were three enucleations for disease progression. Final VA in retained eyes was ≥6/7.5 in 6 (30%), 6/9 to 6/12 in 5 (25%), 6/15 to 6/48 in 2 (10%), and ≤6/60 in 4 (20%) eyes. Retinopathy was the main cause of vision loss besides tumour progression.
