Management of circumscribed choroidal hemangioma at a tertiary care center.

PURPOSE: To review long-term outcomes of circumscribed choroidal hemangioma (CCH). METHODS: Hospital charts of all CCH cases diagnosed from 2008 to 2019 were retrospectively reviewed. RESULTS: All 172 patients were managed with either observation, transpupillary thermotherapy, argon laser photocoagulation, photodynamic therapy, plaque brachytherapy or stereotactic radiosurgery. The most common 3 modes of management were clinical observation (30.2%), transpupillary thermotherapy (52.9%) and argon laser photocoagulation (8.7%). Median follow-up time was 10 months (range: 3, 160). Anatomical outcomes were stable in 87.1% of observation group and improved in 60.5% of thermotherapy group. Quantified optical coherence tomography angiography findings showed statistical differences in vascular and perfusion densities in fellow eyes of hemangioma patients. CONCLUSION: Circumscribed choroidal hemangioma can be treated in various ways. Transpupillary thermotherapy is an anatomically effective treatment in selected cases. The diagnosis of CCH may have vascular implications in fellow eyes of the patients.

Ultrasound Biomarkers: Contrast-enhanced Ultrasound and Nakagami Imaging to Differentiate Benign and Malignant Choroidal Tumor.

PURPOSE: We hypothesized that contrast-enhanced ultrasound (CEUS) using a microbubble technique to quantify microvascular changes and Nakagami imaging for tissue characterization would provide a new approach for diagnosing and differentiating benign and malignant choroidal lesions. METHODS: Five patients with choroidal melanoma (CM) and five patients with choroidal hemangioma (CH) were selected. Definity®, which contains perflutren microbubbles, was administered as a slow IV bolus (1 ml). CEUS was performed for 1 min postinjection of the contrast agent with ultrasound radiofrequency data acquired from 10 s to 60 s. The contrast value was calculated for the whole tumor region. A gradient magnitude method was used for each postcontrast frames with 1-second interval, and the time-averaged value in pixel intensity gradient of postinjection frames was estimated and reported. Based on the Nakagami statistical distribution model, two Nakagami parameters, m and Ω, where m (shape parameter), representing tissue heterogeneity, and Ω (scale parameter), representing the average energy of backscattered signals, were studied. RESULTS: CEUS analysis showed that the time-averaged estimated contrast was significantly higher (p = 0.008) for CH compared to CM. Furthermore, the time-averaged contrast within the normal choroidal region was significantly higher than the choroidal tumor region for both CH and CM (p = 0.001 for CH cases and p < 0.0001 for CM cases). Nakagami analysis showed that the m estimates were significantly higher (p = 0.032) for CH (m = 0.61) than for CM (m = 0.28), indicating that CH is a more heterogeneous tumor than CM. The Ω estimates were significantly higher (p = 0.0019) for CH (Ω = 0.15) compared to CM (Ω = 0.03). These results may be due to the more vascular structures in CH compared to CM. CONCLUSIONS: Quantitative intensity-based perfusion analysis using CEUS and backscattering tissue analysis using Nakagami imaging can provide valuable insights to differentiate benign and malignant choroidal lesions.

Comparison of the therapeutic effects of photodynamic therapy, transpupillary thermotherapy, and their combination on circumscribed choroidal haemangioma.

OBJECTIVE: To characterize the clinical and imaging features of circumscribed choroidal hemangioma (CCH), and to evaluate individualized treatment efficiency of photodynamic therapy (PDT), transpupillary thermotherapy (TTT), or their combination, followed by retrobulbar injection of betamethasone on CCH resolvement. METHODS: Forty-nine patients with CCHs who underwent PDT, TTT or PDT+TTT treatments were retrospectively analyzed. Their treatment efficacy was compared by analyzing the change of best corrected visual acuity (BCVA), subretinal fluid (SRF) and CCH lesion characteristics. RESULTS: PDT, TTT and PDT+TTT were respectively administrated in 17, 11 and 21 patients. No significant difference in age, gender, affected eyes and tumor location across the three groups. Baseline BCVA were 0.41 ± 0.28, 0.62 ± 0.30 and 0.24 ± 0.24 for PDT, TTT and PDT+TTT groups, respectively (F = 6.572, P = 0.003). CCH treated by three strategies showed significant difference in maximum tumor basal diameter, SRF areas and macula involvement prior to the treatment (P < 0.05). Patients receiving PDT+TTT exhibited larger tumor basal diameter, more SRF, higher ratio of macular involvement than other groups. A total of 38 (77.6 %) cases had good visual acidity with final BCVA ≥0.5 after treatments. PDT and PDT+TTT treatment groups acquired more vision improvement (0.27 ± 0.23 and 0.31 ± 0.26) in BCVA than TTT group (0.09 ± 0.13). All SRF were resolved within two weeks of treatment and no recurrent SRF were found. CONCLUSION: The three treatments showed good performance in improving visual function and controlling SRF, and individualized treatment should be selected primarily by the tumor location, and then the tumor size and presence of SRF.

Swept-source optical coherence tomography and swept-source optical coherence tomography angiography findings in circumscribed choroidal hemangioma before and after transpupillary thermotherapy.

PURPOSE: To investigate the swept-source optical coherence tomography (SS-OCT) and SS-OCT angiography (SS-OCTA) findings in circumscribed choroidal hemangioma (CCH) before and after treatment with transpupillary thermotherapy (TTT). METHODS: The clinical records of 21 eyes having CCH imaged with SS-OCT/SS-OCTA between September 2018 and December 2022 were evaluated. RESULTS: SS-OCT examination in CCH showed dome-shaped appearance (100%), choroidal shadowing (100%), expansion of choroidal structures (100%), subretinal fluid (66.7%), intraretinal edema/schisis (33.3%), retinal pigment epithelium (RPE) atrophy (19.0%), hyperreflective dots (19.0%), and epiretinal membrane (4.8%). Internal arborizing tumor vessels showing hyperreflectivity were observed in the choriocapillaris slab on SS-OCTA in all eyes. In the deep capillary plexus (DCP), flow void changes were seen in 7 eyes with intraretinal schisis/cystoid macular edema. Four CCHs > 2 mm in thickness showed outer retinal involvement due to unmasking of flow in intratumoral vessels related to RPE atrophy. Following TTT/indocyanine green-enhanced TTT (ICG-TTT) of CCH, SS-OCT findings included total/partial resolution of subretinal fluid (57.1%), complete/partial regression of the tumor (52.4%), and RPE atrophy (33.3%). After treatment; loss of choriocapillaris, decrease in tumor vascularity together with increase in the fibrous component and flow void areas were detected on SS-OCTA. CONCLUSIONS: SS-OCT/SS-OCTA are useful non-invasive tools for imaging the structural/vascular changes in CCHs managed with TTT or ICG-TTT. On SS-OCTA, hyporeflective spaces localizing to edema/schisis in the DCP and arborizing tumor vessels within a hyporeflective stromal background in the choriocapillaris slab were observed. After TTT/ICG-TTT, a decrease in tumor vessels and an increase in the fibrous component and flow-void areas inside the CCH were detected on SS-OCTA.

Overlapping Spots of Photodynamic Therapy for Treatment of Choroidal Hemangioma in Sturge-Weber Syndrome: A Case Report.

Introduction: Photodynamic therapy (PDT) has shown substantial benefit in the treatment of choroidal hemangioma (CH) in recent years. This report describes the use of PDT with overlapping spots in a patient with Sturge-Weber syndrome (SWS) and large circumscribed CH. Case Presentation: A 9-year-old girl with SWS and a history of glaucoma in her left eye was referred to a retina clinic for possible macular changes. Examination revealed decreased vision in the left eye, pigmentary changes in the macula, and choroidal thickening in the posterior pole. After being lost to follow-up for 2 years, the patient returned with further vision deterioration with best-corrected visual acuity (BCVA) of 20/150 and new subretinal fluid (SRF). Imaging findings were consistent with a diagnosis of CH and SRF. PDT with verteporfin was initiated on the entire area with multiple overlapping spots, resulting in resolution of SRF and improvement in visual acuity and choroidal contour. At 18-month post-treatment, the patient's BCVA was 20/25 with no recurrence of SRF or increased choroidal thickening. Significant pigmentary changes and subretinal hyper-reflective material were observed in the OCT of the treated area. Conclusion: Multiple overlapping laser spots of PDT can result in longstanding regression of large circumscribed CH in a patient with SWS with excellent final visual acuity. However, significant subretinal changes may also result following this method of treatment.

[Circumscribed choroidal hemangioma and non-pigmented choroidal melanoma: clinical, instrumental and molecular genetic features]. / Otgranichennaya gemangioma i bespigmentnaya melanoma khorioidei: kliniko-instrumental'nye i molekulyarno-geneticheskie osobennosti.

Circumscribed choroidal hemangioma (CCH) and early non-pigmented choroidal melanoma (CM) have similar clinical, ultrasound and morphometric features, which in some cases makes their differential diagnosis difficult. There are few studies in the literature devoted to a comparative analysis of the molecular genetic features of CCH and non-pigmented CM, and the results of those studies are contradictory. PURPOSE: This study attempts to develop a method of non-invasive molecular genetic differential diagnostics of CCH and non-pigmented CM. MATERIAL AND METHODS: Based on the results of clinical and instrumental examination methods, 60 patients (60 eyes) with CCH (n=30) and non-pigmented CM (n=30) were included in this prospective study. The control group consisted of 30 individuals without intraocular tumors. Mutations in the GNAQ/GNA11 genes were determined by real-time PCR using the analysis of genomic circulating tumor DNA isolated from peripheral blood plasma. The average follow-up period was 12.1±1.8 months. RESULTS: The study revealed a significant association of mutations in exons 4 and 5 of the GNAQ/GNA11 genes with the presence of non-pigmented CM (27/30; 90%). These mutations were not detected in the group of patients with CCH. Mutations in exons 4 and 5 of the GNAQ/GNA11 genes were also not detected in the control group of healthy individuals. CONCLUSION: This study proposes a method of non-invasive and low-cost differential diagnostics based on molecular genetic analysis and detection of mutations in exons 4 and 5 of the GNAQ and GNA11 genes, which are specific for CM (90%).

Perspectives and Update on the Global Shortage of Verteporfin (Visudyne®).

An ongoing global shortage of verteporfin (Visudyne®) limits the treatment possibilities for several chorioretinal diseases, including central serous chorioretinopathy, choroidal hemangioma, and polypoidal choroidal vasculopathy. Verteporfin is required to perform photodynamic therapy in these ocular diseases. Therefore, the current situation has a substantial impact on eye care worldwide. The worldwide supply of verteporfin appears to be manufactured by a single factory, which is situated in the United States. The distribution of verteporfin is done by different companies for different regions of the world. Official communication on the shortage by the responsible companies has been scarce and over the past years several promises with regards to resolution of the shortage have not been fulfilled. The delivery of new batches of verteporfin is at irregular intervals, unpredictable, and may not be fairly balanced between different regions or countries in the world. To ensure a fair distribution of available verteporfin within a country, several measures can be taken. In the Netherlands, a national committee, consisting of ophthalmologists, is in place to arrange this. On the European level, the European Union and European Medicine Agency have plans to monitor medicine shortages more closely and to intervene if necessary. With a more intensified monitoring and regulation of medicine supplies, future impending shortages may be prevented. Remarkably, the amount of medicine shortages is increasing, having a significant and sometimes irreversible impact on patient care. Thus, efforts should be undertaken to minimize the consequences and, whenever possible, to prevent future medicine shortages.

Ruthenium-106 (106Ru) plaque brachytherapy for treatment of circumscribed choroidal hemangioma.

PURPOSE: To describe the clinical and imaging features of circumscribed choroidal hemangiomas (CCH) and their treatment outcomes with Ruthenium-106 (106Ru) plaque brachytherapy. METHODS: Retrospective study of 24 patients (24 eyes) diagnosed with CCH and treated with 106Ru plaque between 2017 and 2022. Analysis included pre- and post-treatment clinical and imaging features such as tumor regression, reduction in height, subretinal fluid (SRF) resolution, and change in best-corrected visual acuity (BCVA). RESULTS: The mean age at presentation was 36 years (range, 16-57). The most common tumor location was the temporal quadrant (n = 19) with macular involvement (n = 13). Associated features were macular SRF (n = 22) and inferior exudative retinal detachment (n = 10). Nineteen of the 24 patients underwent primary treatment, whereas 5 patients underwent plaque as a salvage treatment. The mean tumor apex dose was 40 Gy. At a median follow-up of 7.5 months (range 3-65 months), 18 eyes showed complete regression, whereas 6 eyes showed partial regression. The mean height decreased from 4.8 (SD 1.28) mm at presentation to 2.5 (SD 1.63) mm. Median BCVA improved from logMAR 1.2 (IQR 0.4-2) at baseline to logMAR 1.05 (IQR 0.1-1.95) (p = 0.4). Complete resolution of the macula and tumor SRF was observed in 15 (68%) and 13 (57%) eyes, respectively. The radiation-related complications observed were radiation maculopathy (4 eyes), retinopathy (1 eye), and vitreous hemorrhage (1 eye). CONCLUSION: Ruthenium-106 plaque brachytherapy is effective for CCH (> 3 mm height) as a primary and salvage treatment for tumors unresponsive to other modalities.

Could a low-dose definitive radiation therapy be the optimal treatment for choroidal hemangioma?

PURPOSE: To determine the efficacy of low-dose intensity-modulated radiation therapy (IMRT)/volumetric intensity-modulated arc therapy (VMAT) in the treatment of symptomatic choroidal hemangioma (CH). MATERIALS AND METHODS: Fifty-three consecutive patients with CH were retrospectively reviewed. All the patients underwent IMRT/VMAT as a unique treatment. Resolution of subretinal fluid (SRF), improvement of best-corrected visual acuity (BCVA), and reduction in tumor thickness were compared before and after radiotherapy. RESULTS: After definitive radiotherapy, 100 % of SRF and 76.7 % of exudative retinal detachment were resolved. 56.6 % of BCVA improvement in more than two lines was observed. The mean best-corrected visual acuity was 20/280 (range, 20/1200-20/40) at diagnosis and 20/100 (range, 20/1200-20/20) after treatment. The mean tumor thickness decreased significantly from 3.8 mm initially to 1.2 mm after treatment (p < 0.01). 66.0 % of patients were delivered with 21.6 Gy (range, 21.6-42 Gy), 84.9 % of fractional dose was 1.8 Gy (range, 1.8-2 Gy). No radiation-induced keratitis, retinopathy, or optic neuropathy were observed. Initial vision (p = 0.042), duration time of vision (p = 0.004), and tumor thickness (p = 0.049) were prognostic factors for vision recovery. CONCLUSION: Low-dose IMRT/VMAT could effectively induce involution of the CH, with reduction of subretinal fluid and relief of damage to the neurosensory retina, which is an effective treatment mode for CH.

New insights on circumscribed choroidal hemangioma: "bench to bedside".

Circumscribed choroidal hemangioma is a rare vascular hamartoma of the choroid, presenting as a red-orange mass at the posterior pole on fundoscopic examination. Despite its benign origin, associated complications such as subretinal fluid, serous retinal detachment, retinoschisis and neovascular glaucoma may lead to serious visual impairment in more than half patients. Because of its similarity to amelanotic choroidal melanoma and choroidal metastasis, differential diagnosis is still challenging for specialists. Multimodal imaging such as ultrasonography, fluorescein angiography, indocyanine green angiography, optical coherence tomography, and optical coherence tomography angiography guides the clinician to the correct diagnosis and the proper follow-up. Treatment is indicated in symptomatic cases in order to resolve exudation and improve visual acuity. Treatment options include photocoagulation, transpupillary thermotherapy, radiation therapy, photodynamic therapy and anti-vascular endothelial growth factor therapy. Currently, photodynamic therapy is the treatment of choice due to its effectiveness and safety. The purpose of this review is to describe the latest knowledge in the etiopathogenesis of the circumscribed choroidal hemangioma, the most recent multimodal imaging findings, and the available treatment options.

Diffuse choroidal hemangioma in pregnancy: Symptomatic diffuse choroidal hemangioma spontaneously resolving postpartum.

We present the case of a pregnant young woman with symptomatic diffuse choroidal hemangioma (CH), diagnosed with Sturge-Weber syndrome (SWS). Three months postpartum, there was full spontaneous resolution of the subretinal fluid and improvement in the visual acuity (VA). A 29-year-old, 31-week pregnant female with a coagulation disorder and enoxaparin (clexane) treatment, complained of a left visual disturbance of 2 weeks duration. On examination, the right eye was normal; left eye VA was 6/12 (20/40) with a left eyelid port-wine stain and on funduscopic examination there was a serous retinal detachment. On ultrasound, there was diffuse thickening of the choroid with a focus superior and nasal to the disc with active vascularization - a diagnosis of diffuse CH was made. Magnetic resonance imaging (MRI) and MR venography studies of the brain and orbit revealed engorged orbital vasculature, and the diagnosis of SWS was made. Three months after Cesarean section with birth of a healthy baby boy, VA returned to 6/9 with full resorption of subretinal fluid. On fundoscopic exam, there were no retinal or vein occlutions but there were tortuous blood vessels with A-V crossing. This is a rare case of newly diagnosed SWS with symptomatic diffuse CH in pregnancy. Postpartum, there was full resolution of the subretinal fluid. A watchful waiting approach can be considered in such cases.

An Update on Multimodal Ophthalmological Imaging of Diffuse Choroidal Hemangioma in Sturge-Weber Syndrome.

Sturge-Weber syndrome (SWS) is characterized by facial port-wine stains, leptomeningeal hemangiomas, and prominent ocular manifestations such as glaucoma and diffuse choroidal hemangiomas (DCHs). Imaging modalities are critical for diagnosing and longitudinally monitoring DCHs in SWS. Fundus photography is fundamental in assessing both eyes simultaneously, fluorescein angiography and indocyanine green angiography effectively map the retinal and choroidal circulation, and ultrasonography offers essential structural insights into the choroid and retina. NIR imaging reveals subtle retinal pigment changes, often overlooked in standard fundus examination. Enhanced depth imaging spectral domain optical coherence tomography (EDI-SDOCT) and swept-source OCT (SSOCT) improve the visualization of the choroidal-scleral boundary, essential for DCH characterization. The potential of OCT angiography (OCTA) is under exploration, particularly its role in predicting signs of disease progression or worsening, as well as potential new biomarkers such as the choroidal vascularity index (CVI). The present review aims to provide an update on multimodal imaging of DCHs in SWS.

Examining the efficacy of verteporfin photo-dynamic therapy (PDT) at different dose & fluence levels.

OBJECTIVES: Photodynamic therapy (PDT) is a vaso-occlusive treatment for a number of chorioretinal vascular pathologies. We aimed to retrospectively analyse efficiency and safety of PDT for different conditions (central serous retinopathy (CSR), age-related macular degeneration (AMD), macular telangiectasia type 2 and choroidal hemangioma) and with different verteporfin parameters. METHODS: Clinical parameters were ascertained from the medical records of patients undergoing PDT over a 6-year period. This included indications for PDT, dosing regimens of verteporfin PDT (which includes treatment dose of verteporfin and fluence). Response to treatment was measured by best corrected visual acuity (BCVA) and central foveal thickness (CFT) on ocular coherence tomography. Complications and side effects were recorded. RESULTS: 67.4 % (31/46) of PDT treatments performed over the last six years were for CSR. In the CSR cohort, there were significant improvements in BCVA (0.47 ± 0.24 to 0.29 ± 0.27, p < 0.05) and CFT (350.2µm ± 66.9 µm to 286.1µm ± 60.6 µm. In the AMD cohort, there was no change in BCVA (1.08 ± 0.52 to 1.07 ± 0.53, p = 0.96) but significant improvement in CFT (488.2µm ± 164.6 µm to 348.7µm ± 65.7 µm, p < 0.05). There was no significant difference in BCVA or CFT for macular telangiectasia type 2 and choroidal hemangioma. CONCLUSIONS: PDT continues to have a role in the management of medical retina conditions. Our results show PDT is most effective in improving and stabilizing visual acuity in CSR, with earlier intervention resulting in better outcomes.

[Multimodal algorithm for differential diagnosis of tumors and tumor-like diseases of the ocular fundus]. / Mul'timodal'nyi algoritm differentsial'noi diagnostiki opukholei i opukholepodobnykh zabolevanii glaznogo dna.

Diagnosing pathologies of the ocular fundus and performing differential diagnosis of intraocular tumors along with conventional ophthalmoscopy can involve additional visualization methods such as ultrasonography, fluorescein angiography and optical coherence tomography (OCT). Many researchers note the importance of employing a multimodal approach in differential diagnosis of intraocular tumors, but there is no universally established algorithm for a rational choice of both the combination of visualizing methods, and the sequence of their application with consideration of the ophthalmoscopy findings and the results of first-line diagnostic methods. The article presents author's own multimodal algorithm developed for differential diagnosis of tumors and tumor-like diseases of the ocular fundus. This approach involves the use of such methods as OCT and Multicolor fluorescence imaging, with exact sequence and combination determined on the basis of ophthalmoscopy and ultrasonography findings.

Does Subretinal Fluid Optical Density Ratio Differ Among the Eyes with Acute Central Serous Chorioretinopathy,Vogt Koyanagi Harada Disease and Choroidal Hemangioma: A Cross-sectional Study.

PURPOSE: To investigate the diagnostic value of optical density ratio (ODR) in various diseases with subretinal fluid (SRF) due to different pathophysiologies. METHODS: Patients with acute central serous chorioretinopathy, CSCR (n = 49), Vogt Koyanagi Harada disease, VKH (n = 34), and choroidal hemangioma (n = 17) characterized with SRF were included. Spectral-domain optical coherence tomography (SD-OCT) images were analyzed using ImageJ by three independent readers. The ODRs were calculated using "region of interest (ROI)" and "entire region (TOTAL)" selection methods from the SRF to the vitreous, retinal nerve fiber layer (RNFL), and retinal pigment epithelium (RPE) reflectivity ratios. A correlation analysis between age, central macular thickness (CMT), SRF height, SRF width, and ODRs were obtained. RESULTS: Optical density (OD) measurement was highly reproducible (intraclass correlation coefficient> 0.9). Optical density of the SRF, vitreous, RNFL, and signal strength were comparable (p = 0.360, p = 0.247, p = 0.105, and 0.628, respectively). There was no difference in SRF OD measurements between the two methods (p = 0.401), while there was a significant difference in vitreous OD measurements (p = 0.016). ANOVA test of ODR(ROI), ODR(TOTAL), ODR-RPE (ROI) and ODR-RNFL (ROI) revealed no significant difference among acute CSCR, VKH disease and choroidal hemangioma groups (p > 0.05 for all). Correlation analysis revealed a significant negative correlation between SRF height (p < 0.05) and CMT (p < 0.01) with SRF ODR(ROI). CONCLUSION: ODR measurement appears to be a highly repeatable SD-OCT parameter for diseases characterized with SRF collection. Despite variations in their pathophysiology, the ODR was not statistically different in acute CSCR, VKH disease, and choroidal hemangioma.

Actualización en el diagnóstico y tratamiento del hemangioma coroideo / Update on the diagnosis and treatment of choroidal hemangioma

El hemangioma coroideo es un tumor vascular benigno dependiente de la circulación coroidea. Se distinguen 2tipos de lesiones: circunscrita, variante más frecuente, y difusa, asociada normalmente al síndrome de Sturge-Weber. El hemangioma coroideo circunscrito se presenta como una masa anaranjada que puede aparecer de manera asintomática, sin embargo, cuando produce síntomas, lo más frecuente es la disminución de la agudeza visual debido a un desprendimiento de retina neurosensorial. Debido a su carácter benigno solo deberían ser subsidiarios de tratamiento aquellos que produzcan síntomas. El conocimiento de esta enfermedad y su correcto diagnóstico diferencial es muy relevante para establecer el diagnóstico y tratamiento adecuado y evitar tratamientos innecesarios. En la actualidad existe una gran variedad de pruebas de imagen de diagnóstico multimodal que nos permiten identificar y realizar un seguimiento adecuado de este tumor. Además, en los últimos años, gracias al empleo de la terapia fotodinámica, se ha producido un cambio en el paradigma del tratamiento de estas lesiones, lo cual ha supuesto una mejora significativa en el pronóstico visual de estos pacientes. Esto se ha debido al empleo de la terapia fotodinámica, como tratamiento de elección para el hemangioma coroideo circunscrito (AU)

Choroidal hemangiomais a benign vascular tumor dependent on the choroid. Two types of lesions are distinguished: circumscribed, the most frequent variant, and diffuse, normally associated with Sturge-Weber syndrome. The circumscribed choroidal hemangioma appears as an orange mass that can present asymptomatically, however, when it produces symptoms, the most frequent is decreased visual acuity due to neurosensory retinal detachment. Due to its benign nature, only those that produce symptoms should be eligible for treatment. Knowledge of this pathology and its correct differential diagnosis is very relevant to establish the appropriate diagnosis and treatment, avoiding unnecessary treatments. There is currently a wide variety of multimodal diagnostic imaging tests that allow us to identify and adequately monitor this tumor. In addition, in recent years, there has been a change in the paradigm of the treatment of these tumors thanks to the use of photodinamic therapy, which has led to a significant improvement in the visual prognosis of these patients. This has been due to the use of photodynamic therapy as the treatment of choice for circumscribed choroidal hemangioma (AU)

Long term results of photodynamic therapy in intraocular tumors.

PURPOSE: To report long term results of photodynamic therapy (PDT) as treatment for intraocular tumors METHODS: Retrospective interventional case series of 15 patients. All patients treated with standard-fluence PDT (83 s; 50 J/cm2) using verteporfin. OUTCOME MEASURES: Tumor diameter, tumor thickness, subretinal fluid resolution, best-corrected visual acuity,intraocular pressure and PDT complications. RESULTS: 10 patients (66.7% of total patients) were diagnosed with choroidal hemangioma, 3 patients (20% of total patients) were diagnosed with choroidal melanoma, and 2 patients (13,3% of total patients) were diagnosed with choroidal osteoma.. Mean follow-up time was 33±18 months. The mean visual acuity was determined as 1.29 ± 0.98 logMAR in the examinations just before the PDT application. At the end of the follow-up period, the mean visual acuity was calculated as 1.41 ± 1.07 logMAR. While VA increased in 3 (20%) patients and decreased in 5 (33.3%) patients; It was determined that VA value did not change after treatment in 7 (46.7%) patients. The mean lesion diameter before PDT was 6573 ± 2115 µm (range; 1500-10,000 µm). The mean tumor thickness before PDT was 3624 ± 1404 µm (range; 600-6000 µm). The mean lesion diameter after treatment was 6026 ± 2521 µm (range; 0-9000 µm), and the mean tumor thickness after treatment was 2280 ± 1740 µm (range; 0-6000 µm).After the PDT, tumor size decreased in 8 (53.3%) patients, increased in 3 (20%) patients, and no change in tumor size was observed in 4 (26.7%) patients. Mean IOP values of all patients were 14.06 ± 3.17 mmHg before treatment; after treatment, it was measured as 13.46 ± 1.70 mmHg. After the treatment, geographic atrophy developed in 1 (6.7%) patient, cystoid macular edema developed in 1 (6.7%) patient, Retinal Pigment Epithelium (RPE) and choroidal atrophy developed in 1 (6.7%) patient. CONCLUSION: There are not enough cases of each to clearly distinguish between these 3 types of ocular cancers.However PDT may be a good option in the treatment of intraocular tumors with the chance of selective treatment and successful response.

Occurrence of circumscribed choroidal hemangioma accompanied by polypoidal choroidal vasculopathy and branch retinal vein occlusion: a case report.

BACKGROUND: Circumscribed Choroidal hemangioma (CCH) is a kind of hamartoma that is caused by congenital vascular malformation. And, polypoidal choroidal vasculopathy (PCV) is an exudative maculopathy. There is no literature indicating that there is a correlation between the occurrences of CCH and PCV. CASE PRESENTATION: A 66-year-old male presented with decreased vision of his left eye for 4 years. Fundus photograph showed that the branches of blood vessels at the supratemporal retina were occluded in white lines, an orange lesion could be seen in the subnasal retina and mottled, yellowish white lesions were accompanied by punctate hard exudation in the macular in the left eye. The Fundus autofluorescence (FAF), fundus fluorescein angiography (FFA), indocyanine green angiography (ICGA) and Spectral domain optical coherence tomography (OCT) were done. There was a diagnosis of CCH, PCV and branch retinal vein occlusion accompanied with retinoschisis of the left eye. CONCLUSION: This article reports on a case of an elderly male Chinese patient with CCH and PCV accompanied by branch retinal vein occlusion with retinoschisis in the left eye. The common lesions are choroidal vascular abnormalities. Whether hypertension is related to CCH, PCV and branch retinal vein occlusion remains to be further studied.

Update on the diagnosis and treatment of choroidal hemangioma.

Choroidal hemangioma (CH) is a benign vascular tumor dependent on the choroid. Two types of lesions are distinguished: circumscribed (CCH), the most frequent variant, and diffuse (DCH), normally associated with Sturge-Weber syndrome. HCC appears as an orange mass that can present asymptomatically, however, when it produces symptoms, the most frequent is decreased visual acuity due to neurosensory retinal detachment. Due to its benign nature, only those that produce symptoms should be eligible for treatment. Knowledge of this pathology and its correct differential diagnosis is very relevant to establish the appropriate diagnosis and treatment, avoiding unnecessary treatments. There is currently a wide variety of multimodal diagnostic imaging tests that allow us to identify and adequately monitor this tumor. In addition, in recent years, there has been a change in the paradigm of the treatment of these tumors thanks to the use of photodinamic therapy, which has led to a significant improvement in the visual prognosis of these patients. This has been due to the use of photodynamic therapy as the treatment of choice for HCC.

Retinal Imaging and Optical Coherence Tomography of Choroidal Haemangioma Mimicking Central Serous Chorioretinopathy.

Intraocular tumours, such as choroidal haemangioma, can cause exudative retinal detachments, which mimic central serous chorioretinopathy. Key symptoms of a choroidal haemangioma include reduced visual acuity, visual field defects, and metamorphopsia. More rarely, it can cause photopsia, myodesopsia, and pain. Important differentials include choroidal melanoma and metastases, for which an ocular oncologist should be consulted. Prompt treatment is required for the regression of tumour and to prevent choroidal atrophy and permanent visual loss. Here, we report the case of a 44-year-old lady who was found to have a choroidal haemangioma with macular subretinal fluid, highlighting the differentiating features from other intraocular masses.
