RESUMO
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.

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.

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.

Optical coherence tomography (OCT) is currently widely used for the diagnosis of choroidal melanoma (CM), but the problem of predicting the outcomes of planned CM treatment remains unsolved. PURPOSE: This study was conducted to identify OCT signs that adversely affect the outcome of organ-preserving CM treatment. MATERIAL AND METHODS: OCT scan images of 30 patients who underwent organ-preserving treatment and were under observation were selected for this study. Brachytherapy (BT) as monotherapy was performed in 27 patients (in 2 cases - twice, and in 1 case - three times), in one patient - in combination with the previous transpupillary thermotherapy (TTT). Multiple TTT (4 sessions within 4 months) as monotherapy were performed in 2 patients. In 9 cases, a single organ-preserving treatment (BT - 6 patients, TTT - 3 patients) was ineffective. In these cases, the effectiveness of the first stage of organ-preserving treatment was taken into account. RESULTS: Seven signs of an unfavorable prognosis of the performed treatment were identified by analyzis of tomograms and statistical processing of the obtained data. These signs include: the presence of intraretinal edema, detachment of the neuroepithelium (NED) over the tumor, including with a break in the photoreceptors, accumulation of transudate over the tumor, the presence of large cysts, intraretinal cavities and NED near the tumor (secondary retinal detachment). A combination of three or more signs were observed in all cases of inefficiency of the first stage of treatment. Most often, intraretinal edema and NED over the tumor were combined with the accumulation of subretinal transudate and NED near the tumor. The presence of 6 or all 7 signs took place in cases of a negative therapeutic effect after local destruction. CONCLUSION: When planning organ-preserving CM treatment, in addition to biometric parameters, it is necessary to pay special attention to the identification of such morphological signs as NED over and near the tumor, accumulation of transudate under the NED, the presence of intraretinal edema, large intraretinal cysts and cavities.

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.

BACKGROUND: Metastatic choroidal tumors are hematogenous intraocular metastases of malignant tumors in systemic organs; however, the details of choroidal circulation and morphological changes in the choroid are unknown. The aim of this study is to present a case of metastatic choroidal tumor and examine laser speckle flowgraphy (LSFG)-based choroidal circulation and central choroidal thickness (CCT) before and after chemoradiotherapy. CASE PRESENTATION: A 66-year-old woman with a medical history of breast cancer 16 years ago was referred to our department struggling with blurred vision in her right eye. At the time of initial examination, her best-corrected visual acuity (BCVA) was 0.4 oculus dexter (OD) and 0.9 oculus sinister. Fundus revealed a yellowish-white choroidal elevated lesion measuring 8 papillary diameters with serous retinal detachment (SRD) in the posterior pole. Fluorescein angiography showed diffuse hyperfluorescence and fluorescent leakage due to SRD, and indocyanine green angiography demonstrated no abnormalities in the macula but hypofluorescence in the center of the tumor. Based on these clinical findings, she was diagnosed with metastatic choroidal tumor. After chemoradiotherapy, the metastatic choroidal tumor became scarred, and SRD disappeared. The rate of changes in macular blood flows assessed by mean blur rate on LSFG and CCT of her right eye were 33.8 and 32.8% decrease at 5 months after the initial visit, respectively. BCVA was 0.5 OD 27 months after the initial examination. CONCLUSION: Chemoradiotherapy resulted in regression of the metastatic choroidal tumor and disappearance of SRD, with a decrease in central choroidal blood flow and CCT. The choroidal blood flow on LSFG could reflect an increased oxygen demand by cancer cells invading the choroid and substantial blood supply.

Choroidal osteoma is a benign ossifying tumor within the choroid. Complications associated with choroidal osteoma, including disruption of retinal pigment epithelium, atrophy of photoreceptors, subretinal fluid, and choroidal neovascularization, present challenges for clinicians, and management remain controversial. We performed a comprehensive search in the PubMed, EMBASE, and Ovid databases for published studies and case reports relating to the management of choroidal osteoma. Since it was first described in 1978, various case reports of ocular complications associated with choroidal osteoma have been documented, and various therapies have yielded different outcomes. We systematically evaluate the literature published on this rare entity.

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.

It can be difficult for practitioners to determine the likelihood of malignancy in melanocytic choroidal tumours. This author has therefore devised the MOLES acronym to highlight the most informative clinical features, which comprise mushroom shape, orange pigment, large size, enlargement, and subretinal fluid. Each of these is scored 0 if absent, 1 if subtle or uncertain, and 2 if present. Tumours are categorised as 'common naevus', 'low-risk naevus', 'high-risk naevus' and 'probable melanoma' according to whether the sum of these five scores is 0, 1, 2 or 3 or more, respectively. Tentative recommendations, subject to future studies, include: review of 'common naevi' by a community optometrist whenever the patient attends for another reason, such as a two-yearly 'check-up' (i.e., 'self-care'); non-urgent referral of patients with 'low-risk naevi' or 'high-risk naevi' to an ophthalmologist to plan long-term surveillance (i.e., determining the frequency of assessments and whether these should be undertaken by an ophthalmologist or a community optometrist); and urgent referral of patients with a MOLES score >2 (i.e., 'probable melanoma') to an ophthalmologist for immediate referral to an ocular oncologist if a suspicion of malignancy is confirmed. The MOLES system does not require assessment of internal acoustic reflectivity by ultrasonography. MOLES scores correlate well with diagnosis of choroidal naevi and melanomas by ocular oncologists; however, further evaluation of this aid in routine optometric practice and other situations is needed. MOLES should prevent unnecessary referral of patients with naevi for second opinion and non-essential monitoring of these patients at hospital eye services.

CLINICAL RELEVANCE: Although melanocytic choroidal tumours of the choroid are a common eye pathology, no standardised protocol exists for their management in the community. BACKGROUND: Choroidal naevi are found in approximately 6% of the adult White population, whereas choroidal melanomas are rare, with an annual incidence of 5-10/million/year. Multimodal imaging has advanced the understanding of malignancy imaging biomarkers, but distinguishing between a small melanoma and naevus remains difficult and an algorithm for their management by community practitioners has not been uniformly adopted. One of the authors (BD) devised the MOLES scoring system, which indicates malignancy likelihood according to mushroom shape, orange pigment, large size, enlargement, and subretinal fluid. When applied by ocular oncologists, the system accurately distinguishes choroidal naevi from melanomas. The aim of this study was to evaluate whether community optometrists can appropriately manage patients with melanocytic choroidal tumours using this system. METHODS: Clinical images of 25 melanocytic choroidal tumours were presented in an online survey, including colour fundus photographs, fundus autofluorescence, optical coherence tomography, and B-scan ultrasound images. Using the MOLES system, 39 optometrists diagnosed tumours as naevus or probable melanoma and decided between community monitoring and ophthalmologist referral. Responses were compared to MOLES grading of the same clinical images by ocular oncologists. RESULTS: Using MOLES, optometrists correctly identified 389/406 probable melanomas (95.8% sensitivity) and 331/516 choroidal naevi (64.1% specificity); correctly referred 773/778 tumours to an ophthalmologist (99.4% sensitivity); and correctly managed 80/144 lesions (55.6% specificity) in the community. CONCLUSION: Optometrists safely applied the MOLES scoring system in this survey. Further measures are indicated to reduce choroidal naevi over-referral and evaluate MOLES system usage in clinical optometric practice, where some imaging modalities may not be readily available.

Laser treatment has offered a relatively nonsurgical alternative for eye, life, and vision-sparing treatment of malignant melanoma of the choroid. Historically, the most commonly used forms of lasers were xenon-arc, argon laser, krypton laser, and the more recent transpupillary thermotherapy (TTT) and photodynamic therapy (PDT). Melanomas selected for laser treatment tend to be smaller and visibly accessible, which means these tumors are usually located in the posterior choroid. Laser treatments have been associated with both local tumor destruction and side effects. Unlike radiation therapy, laser treatment has been commonly associated with retinal traction, hemorrhage, chorioretinal neovascularization, and extra scleral tumor extension, as well as higher rates of local treatment failure. In addition, however, laser-treatment has been successfully used to treat tumor-related retinal detachments, radiation retinopathy, and neovascular glaucoma. We review the world's experience of ophthalmic laser treatment for choroidal melanoma, offer safety and efficacy guidelines, as well as a comparison of laser treatment to radiation therapy outcomes.

AIMS: To propose diagnostic criteria for a presumed incipient choroidal melanoma based on tumour growth rate and tumour doubling time (TDT) and to describe management of such tumours with transpupillary thermotherapy (TTT). METHODS: Retrospective interventional case series of nine consecutive presumed incipient uveal melanomas diagnosed and treated with TTT in 2010-2017. Growth rate in mm/year and per cent/year in largest basal diameter (LBD) and TDT were compared with published data for uveal melanomas and growing naevi that did not transform to melanoma under long-term follow-up. RESULTS: The median LBD and thickness were 1.6 mm (range 0.9-2.3) and 0.20 mm (range 0.15-0.29), respectively. The median age was 57 years (range 47-78). Seven tumours were classified as de novo melanomas and two as transformed naevi. The median time from first observation to diagnosis was 3.3 years (range 2.2-7.3), LBD growth rate 0.25 mm/year (range 0.11-0.72) and 34 per cent/year (range 10-1437), and TDT 609 days (range 97-1612). The estimates matched those reported for uveal melanoma (median TDT 521 days, 90th percentile 2192) and exceeded those for growing naevi (median growth rate 0.04 mm/year, 90th percentile 0.12; 1.1 per cent/year, 90th percentile 2.6). The predicted median age at de novo appearance was 51 years (range 32-63). No tumour grew after TTT during a median follow-up of 2.1 years (range 0.6-8.7). CONCLUSIONS: In this series, relative growth rate and TDT best qualified as diagnostic criteria for an incipient choroidal melanoma. Too small for brachytherapy, they could be managed with TTT.

BACKGROUND: Choroid, ciliary body, and iris melanomas are often grouped as uveal melanoma, the most common intraocular primary malignancy. The purpose of the current study was to analyze the tumor profile of newly diagnosed cases of choroidal melanoma at a reference center in Sao Paulo, Brazil, and to investigate the frequency of eyes treated by enucleation that could have been treated with brachytherapy if available in the service. METHODS: Medical records of patients referred to our service with initial diagnostic hypothesis of choroidal melanoma from July 2014 to June 2020 were analysed on demographics, diagnosis confirmation, tumor measurement by ultrasonography and established treatment. Data were evaluated on clinical and demographic characteristics as age, sex, affected eye, ultrasound parameters, and treatment management of patients with clinically diagnosed choroidal melanoma. Among the patients submitted to enucleation, we investigated how many could have been selected to receive brachytherapy. RESULTS: From the 102 patients referred with the choroidal melanoma diagnosis hypothesis, 70 (68.62%) were confirmed. Mean measurements from the tumors in millimetres were: 9.19 ± 3.69 at height and 12.97 ± 3.09 by 13.30 ± 3.30 at basal. A total of 48 cases (68.57%) were enucleated, 8 (11.43%) were treated by brachytherapy in a different service, and 14 patients (20.00%) returned for enucleation at their original referral center. Out of the 48 patients enucleated, 26 (54.17%) could have been selected to brachytherapy treatment. CONCLUSIONS: The results indicate a late diagnosis of choroidal melanoma cases referred to our service. Most enucleated cases could have been treated with brachytherapy if it was broadly available at the national public health insurance. Further public health political efforts should focus on early diagnosis and better quality of life post-treatment for oncologic patients.

PURPOSE: To quantify potential loss (loss of vision) and gain (freedom from metastasis) in patients with small choroidal melanoma treated after a period of surveillance to document growth. METHODS: A total of 167 patients with small choroidal melanoma (size: 5.0-16.0 mm in largest basal diameter and 1.0-2.5 mm in height) were identified: 42 treated after surveillance (documented growth) and 125 treated immediately. A prediction model was applied to each patient in the immediate treatment group to obtain the predicted risk of melanoma (high risk vs low risk). Potential loss (loss of vision) and gain (freedom from metastasis) were compared between the low-risk immediate treatment group and those treated after surveillance. RESULTS: By using the optimal cut point (0.60; 95% confidence interval: 0.37-0.61) of predicted risk for small choroidal melanoma (sensitivity: 0.74, specificity: 0.95), we identified 94 (75%) patients as high risk (score: ≥0.6) and the remaining 31 (25%) as having low-risk melanoma (score: <0.6). Over a median follow-up of 34.6 months, 5 developed metastasis (high risk = 4, low risk = 1) compared with 1 patient in the surveillance group. Initial visual acuity and loss of <15-letter visual acuity were not significantly different at 36 months between the low-risk patients immediately treated and those treated after surveillance (81% vs 83%), respectively. CONCLUSIONS: Low-risk choroidal melanoma identified by the prediction model can be labeled as an indeterminate melanocytic tumor. Such patients can be managed by surveillance to document growth before receiving vision-threatening treatment without increased risk of metastatic death.

RESUMO O hemangioma de coroide é um tumor vascular benigno, de coloração vermelho-alaranjada, bem delimitado, caracterizado por uma placa elevada. É um tumor raro, com prevalência de um caso a cada 40 tumores de coroide. O diagnóstico pode ser feito por meio da clínica associada à avaliação biomicroscópica e a exames complementares para diferenciação de outros tumores. O tratamento pode ser expectante nos casos assintomáticos. Para os casos sintomáticos ou com presença de fluido sub-retiniano, existem diversas terapias. O objetivo deste estudo foi relatar um caso de hemangioma circunscrito de coroide submetido a tratamento combinado de terapia fotodinâmica com verteporfina e injeção intravítrea de antiangiogênico (bevacizumabe). A decisão de tratar um hemangioma de coroide deve ser individualizada com base nos sintomas, na perda visual e em qualquer potencial de sua recuperação. O exame oftalmológico completo é necessário, mesmo em casos assintomáticos, para rastreamento precoce de doenças oculares.
ABSTRACT Choroid hemangioma is a benign, well-delimited orange-red, vascular tumor characterized by an elevated plaque. It is a rare tumor with a prevalence of one case in every 40 choroidal tumors. It can be diagnosed by the clinic associated with biomicroscopic evaluation and complementary tests to differentiate from other tumors. Treatment can be expectant in asymptomatic cases. For symptomatic cases or those with the presence of subretinal fluid, there are several therapies. The objective of this study was to report a case of circumscribed choroidal hemangioma submitted to combined treatment of photodynamic therapy with verteporfin and intravitreal injection of an antiangiogenic agent (bevacizumab). The decision to treat choroidal hemangioma must be individualized based on symptoms, visual loss, and any potential for recovery. A complete eye examination is necessary, even in asymptomatic cases, for early screening for eye diseases.

OBJECTIVE: To assess the long-term prognosis for patients with iris melanomas and compare it with the prognosis for small choroidal melanomas. DESIGN: Retrospective observational case series. METHODS: All patients treated for iris melanomas at a single referral institution between January 1st 1986 and January 1st 2016 were included. Patients treated for small choroidal melanomas during the same period were included for comparison. The cumulative incidence of melanoma-related mortality was calculated. Patient and tumor characteristics and size-adjusted hazard ratio (HR) for melanoma-related mortality were compared between iris and small choroidal melanomas. RESULTS: Forty-five iris melanomas and 268 small choroidal melanomas were included. Twenty-four iris melanomas (53%) had been treated with local resection, 12 (27%) with Ruthenium-106 brachytherapy, 7 (16%) with enucleation and 2 (4%) with proton beam irradiation. Twenty-one (68%), 7 (16%) and 2 (4%) of the iris melanomas were of the spindle, mixed and epithelioid cell types, respectively. Twenty-three patients had deceased before the end of follow-up. Median follow-up for the 22 survivors was 13.3 years (SD 9.4). Patients with iris melanomas were more often asymptomatic at presentation and had a trend towards significantly lower age (59 versus 63 years, Student's T-tests p = 0.057). Further, iris melanomas had significantly smaller basal diameter (5.8 versus 8.0 mm, p < 0.0001) and tumor volume (79 mm3 versus 93 mm mm3, p < 0.0001) but greater thickness (3.0 versus 2.5 mm, p < 0.0001). The cumulative incidence of iris melanoma-related mortality was 5% at 5 years after diagnosis, and 8% at 10, 15 and 20 years. The incidence was not significantly different to small choroidal melanomas (Wilcoxon p = 0.46). In multivariate Cox regression with tumor diameter and thickness as covariates, patients with choroidal melanomas did not have increased HR for melanoma-related mortality (HR 2.2, 95% CI 0.5-9.6, p = 0.29). Similarly, there were no significant survival differences in matched subgroups (Wilcoxon p = 0.82). CONCLUSIONS: There are no survival differences between iris and choroidal melanomas when adjusting for tumor size. The reason for the relatively favorable prognosis of iris melanomas compared to melanomas of the choroid and ciliary body is likely that they are diagnosed at a smaller size.

Achieving local tumor control is generally considered to be the criterion of effectiveness of organ preservation treatment. In most cases it can be assessed by ophthalmoscopy and ultrasonography. However, in presence of pigmentation areas, it can be difficult to interpret the ophthalmoscopy and ultrasonography findings. The works concerning the informativity of optical coherence tomography (OCT) after organ preservation treatment of choroidal melanomas (CM) generally cover the complications (post-radiation maculopathy, neuropathy) and the identification of vitreomacular tractions. In evaluation of local control, attention is paid to the presence of subretinal fluid and/or retinal pigment epithelium (RPE) detachment. PURPOSE: To analyze OCT findings in terms of the condition of eye fundus tissues in various outcomes of organ preservation treatment of CM. MATERIAL AND METHODS: The study included 20 patients (20 eyes) who underwent the following organ preservation therapy 1 to 374 months prior to enrollment: transpupillary thermotherapy (TTT) - 8 eyes, brachytherapy (BT) - 8 eyes, BT with subsequent TTT - 4 eyes. Mean age of patients at the time of therapy start was 59.25±10.86 (33-81) years. In multi-step therapy (12 eyes), the mean interval between the stages was 28.08±20.39 months. According to echobiometry findings, tumor prominence at the time of therapy start was 3.35±2.08 (1-7.37) mm. At the time of post-treatment OCT scan, there was no prominence in 5 eyes, in other eyes it was 1.26±1.24 (0.4-5.7) mm. RESULTS: Comparison of ophthalmoscopy picture with OCT findings allowed identification of the following changes: a scar and hyperplasia of pigment epithelium in the scar, a scar with reactive pigment hyperplasia at the level of RPE and choroid, radioreaction, growth area from under and inside the scar, incomplete local control, absence of local control. CONCLUSION: The author's own expertise in evaluating the effectiveness of local choroidal melanoma therapy suggests that optical coherence tomography should be used to monitor all patients being followed up after organ preservation treatment of choroidal melanoma: after transpupillary thermotherapy - for 3 months, after brachytherapy - during first 24 months, and in case of doubts for longer.

BACKGROUND: The main objective was to describe metastatic and survival rates in patients with small choroidal melanocytic lesions initially managed by observation. METHODS: Retrospective, observational study of consecutive cases recruited from 2001 through 2018, followed for a median (mean, range) of 81.0 (89.3, 10-204) months in a tertiary referral centre for ocular oncology. Seventy-five consecutive patients diagnosed with small choroidal melanocytic lesions with risk factors for growth initially observed and who showed progression during follow-up. Treatment was performed (plaque radiotherapy or enucleation in 96% and 4% of cases, respectively) at detection of tumour growth. RESULTS: Median (mean, range) tumour thickness was 2.2 (2.23, 1.08-3.40) mm, and median maximum basal diameter was 8.5 (8.16, 4-12) mm. At diagnosis, a median (mean, range) of 5 (5.48, 1-8) risk factors for progression were present. Lesions grew at a median (mean, range) rate of 0.42 mm/y (1.12, 0-7.68) in thickness and 1.05 mm/y (3.14, 0-4.8) in maximum diameter. Median (mean, range) time until growth was 17.00 (32.6, 1-161) months post-diagnosis, at which time tumours were treated. Five patients developed local recurrence after brachytherapy requiring enucleation. Four patients developed hepatic metastasis. Melanoma-specific survival was 98% at 5 years (95% CI, 94.2-100%) and 91.6% (95% CI, 82-100%) at 10 and 15 years. CONCLUSION: In small melanocytic lesions with risk factors for growth, initial observation until detection of tumour growth results in a seemingly low risk of metastasis, suggesting that this may be an initial approach to consider in tumours with indeterminate malignant potential.
