Abstract
PURPOSE The role of the choroid in Leber hereditary optic neuropathy (LHON) remains unclear. The literature is scarce, with conflicting results and lacks axial length measurements. Therefore, we aimed to analyse the choriocapillaris (CC) vessel density (VD) and choroidal thickness (ChT) in all stages of LHON using swept source (SS) technology and considering the possible influence of axial length on choroidal parameters. METHODS This was a prospective cross-sectional observational study. A total of 119 eyes of 60 patients with molecularly confirmed LHON across all stages and 120 eyes of 60 control participants were included. We obtained the CC VD using optical coherence tomography angiography maps centred on the fovea. ChT was measured from the Bruch's membrane to the choroid-sclera interface in the macular and peripapillary regions. RESULTS The CC VD was not significantly affected in any sector or average, except for a slight change in the superior region of chronic eyes (52.08 ± 1.62% vs. 53.50 ± 2.29%, p = 0.002). ChT demonstrated a trend towards decreased values in asymptomatic eyes and increased values in the symptomatic stages that failed to reach statistical significance in sectors corresponding to the papillomacular bundle except for the macular nasal inner sector of chronic eyes (281.10 ± 67.12 μm vs. 252.08 ± 70.55 μm, p = 0.045). No significant correlations were observed between visual acuity and CC VD or ChT. CONCLUSION The CC VD remained stable across the LHON stages. Choroidal vasculature does not appear to play a role in LHON pathophysiology. Further research is needed on ChT as a potential biomarker of LHON.

Abstract
Uveal melanoma is the most common intraocular malignancy in adults. Despite the effective primary treatment, up to 50% of patients with uveal melanoma will develop metastatic lesions mainly in the liver, which are resistant to conventional chemotherapy and lead to patient's death. To date, no orthotopic murine models of uveal melanoma which can develop spontaneous metastasis are available for preclinical studies. Here, we describe a spontaneous metastatic model of uveal melanoma based on the orthotopic injection of human uveal melanoma cells into the suprachoroidal space of immunodeficient NSG mice. All mice injected with bioluminescent OMM2.5 ( n = 23) or MP41 ( n = 19) cells developed a primary tumor. After eye enucleation, additional bioluminescence signals were detected in the lungs and in the liver. At necropsy, histopathological studies confirmed the presence of lung metastases in 100% of the mice. Liver metastases were assessed in 87 and in 100% of the mice that received OMM2.5 or MP41 cells, respectively. All tumors and metastatic lesions expressed melanoma markers and the signaling molecules insulin-like growth factor type I receptor and myristoylated alanine-rich C-kinase substrate, commonly activated in uveal melanoma. The novelty of this orthotopic mouse xenograft model is the development of spontaneous metastases in the liver from the primary site, reproducing the organoespecificity of metastasis observed in uveal melanoma patients. The faster growth and the high metastatic incidence may be attributed at least in part, to the severe immunodeficiency of NSG mice. This model may be useful for preclinical testing of targeted therapies with potential uveal melanoma antimetastatic activity and to study the mechanisms involved in liver metastasis.

Abstract
PURPOSE To investigate the macular and circumpapillary retinal microvasculature across all stages of Leber hereditary optic neuropathy (LHON) using swept source optical coherence tomography angiography (OCTA). METHODS This prospective, multicentre, cross-sectional, observational study analysed a total of 119 eyes of 60 patients with molecularly confirmed LHON across all stages and 120 eyes of 60 control subjects. Optical coherence tomography angiography maps centred on the fovea and optic disc were obtained to measure vessel densities (VDs) in the macular superficial (SCP) and deep (DCP) capillary plexuses, and the radial peripapillary capillary plexus (RPCP) respectively. RESULTS In asymptomatic eyes, only the SCP showed significant changes on average (B coefficient = -0.72, 95% CI = -1.34 to -0.10, p = 0.022) or in sectors representing the papillomacular bundle (PMB) (B coefficient = -1.17, 95% CI = -2.23 to -0.11, p = 0.031). However, in chronic eyes, the greatest magnitude of change was found in the temporal sector of the RPCP (B coefficient = -12.36, 95% CI = -14.49 to -10.23, p < 0.001). The RPCP showed the strongest correlations with visual acuity (VA, logarithm of the minimum angle of resolution; R = -0.677, p < 0.001) and structural parameters (R = 0.747, p < 0.001). CONCLUSIONS Retinal VD changes in the circumpapillary region of the PMB appear later than in the macula but end up being more profound and correlate better with VA and structural parameters. Further studies are needed to assess the clinical utility of retinal VDs as potential LHON biomarkers.

Abstract
PURPOSE To describe the management of an iris stromal cyst by fine needle aspiration and irrigation with absolute alcohol to induce cyst sclerosis. METHODS We present the case of a 45-year-old patient with no previous history referred for a 3-month history of an iris lesion in his right eye. Examination revealed a 2.1×3mm cyst with transparent walls at the right inferonasal iris root, and a primary acquired iris stromal cyst was diagnosed. Initially, observation was recommended, but at the 2-month follow-up, growth of the lesion was observed, so fine needle aspiration and cryotherapy were performed, with recurrence after 2 months. Subsequently, fine needle aspiration and irrigation with absolute alcohol for 2minutes to induce sclerosis of the cyst was carried out. Two weeks after surgery, argon laser was performed on the iris root and remaining walls of the cyst to induce adherence. RESULTS After 1 year of the procedure, the patient remains asymptomatic, without associated complications. A depression and hyperpigmentation of the iris in the inferonasal sector persists, without recurrence of internal fluid or increase in cyst volume. Endothelial cell count and intraocular pressure monitoring have remained stable. CONCLUSION Iris stromal cyst sclerosis by aspiration and irrigation with absolute alcohol was effective and avoided complications associated with resection of the lesion.

Abstract
PURPOSE To describe retinal alterations detected by swept-source optical coherence tomography (SS-OCT) in paediatric patients with Usher syndrome type 1 (USH1) and to compare these findings to previously published reports. METHODS Thirty-two eyes from 16 patients (11 males and 5 females) with a genetic diagnosis of USH1 because of MYO7A mutations underwent SS-OCT. Patients ranged in age from 4 to 17 years (mean, 11,13 ± 4,29). The subfoveal and macular area were analysed with SS-OCT at 1050 nm using 12 radial scans of 12.0 mm. Structural abnormalities were evaluated and correlated with best-corrected visual acuity (BCVA). RESULTS The most common qualitative retinal abnormality was external layer damage in macular area. Specific alterations included external limiting membrane loss/disruption (27 eyes; 84.4%), disruption of the Myoid zone (27 eyes; 84.4%); Ellipsoid zone disruption (28 eyes; 87.5%), and loss of the outer segments (29 eyes; 90.6%). The damage of the retinal pigment epithelium was divided according to the loss of the different layers: phagosome zone (30 eyes; 93.8%), melanosome zone (29 eyes; 90.6%) and mitochondria zone (0 eyes; 0%). The presence of cystoid macular oedema (CMO) was significantly correlated with alterations in photoreceptors. Disruption or absence of the myoid and ellipsoid zones of the photoreceptors were the only variables independently associated with decreased BCVA. CONCLUSIONS The findings of this study suggest that the physiopathologic basis of early-stage Usher syndrome (USH) may be changes in the outer retinal layer, particularly the photoreceptors, which in turn may cause alterations-such as CMO-in the inner retinal layers. Accordingly, monitoring the condition of photoreceptors during follow-up may be advisable for the early detection of pathologic changes.

Abstract
AimsThe aim of this study was to compare transscleral resection technique performed without hypotensive anaesthesia (TSRWH) with iodine-125 brachytherapy (IBT) in the treatment of choroidal melanoma.Patients and methodsThis was a retrospective surgical cohort study. Nineteen eyes treated with TSRWH were matched with 53 eyes treated with IBT according to: tumour size, distance to fovea, distance to optic nerve, and follow-up time. Best-corrected visual acuity (BCVA), local recurrence, secondary enucleation, metastasis, overall and specific survival, and complications were evaluated.ResultsPatients treated with TSRWH had significantly better BCVA than those treated with IBT. The local recurrence risk was significantly higher when ciliary body was involved (HR=11.4, 95% CI 2.24-49.7, P=0.04). Metastatic disease was observed in 14 of 53 patients (26.4%) in the IBT group vs 3 patients (15.8%) in the TSRWH group (P=0.531). Multivariate analysis showed that iris involvement (HR=16.0, 95% CI 4.2-170.2, P=0.033) and large tumour (HR=2.3, 95% CI 1.2-4.8, P=0.04) increased the probability of metastasis. During follow-up, six patients (11.3%) in IBT group died vs two (10.5%) in the TSRWH group (P≥0.999). Nine patients required secondary enucleation: 5 (9.4%) in the IBT group vs 4 (21.1%) in the TSRWH group (P=0.231). The most common complications in IBT group were radiation-induced retinopathy (45.3%), neovascular glaucoma (28.3%), and macular oedema (24.5%), whereas rhegmatogenous retinal detachment (21.1%), ocular hypertension (21.1%), and submacular haemorrhage (15.8%) were the most frequent complications after TSRWH.ConclusionTSRWH is a technically challenging procedure. However, when performed successfully, this technique achieves better preservation of visual acuity than IBT and without the limitations inherent in hypotensive anaesthesia.

Abstract
PURPOSE To investigate the presence of known cytogenetic alterations of choroidal melanoma in a series of patients diagnosed and treated in our Ocular Oncology Service. A review of the present literature on this topic is also presented. METHODS Microsatellite analysis (MSA) studies on loss of heterozygosity (LOH) of chromosome 3, as well as multiplex ligation prove amplification (MLPA) on chromosomes 1, 3, 6 and 8, were performed on enucleation or local resection samples obtained from a total of 27 patients, over a 2 year period. RESULTS Twenty patients showed at least one of the cytogenetic alterations looked for. A total of 11 cases were found that showed LOH of chromosome 3 (44%), 8 gains of chromosome 8 (30%), 8 gains of chromosome 6p (30%), and 7 partial or total losses of chromosome 1 (26%). CONCLUSIONS This is the first study on the cytogenetics of choroidal melanoma performed in our country. The results are similar to that published in the literature. Cytogenetic analysis provides more accurate knowledge on a vital individual prognosis. It also may become a valuable tool for establishing the most adequate follow-up regimes, and the need for adjuvant therapies.

Abstract
Background Fluid-air exchange during vitreoretinal surgery is often used as a tool for subretinal fluid endodrainage. Soft-tipped flexible extrusion cannulas are commonly used to aspirate the posterior subretinal fluid. Methods This is an observational two-case series describing two patients who underwent 20-G pars plana vitrectomy complicated by the accidental fall of the silicone sleeve of a soft-tipped extrusion cannula into the vitreous cavity. In the first case, the cannula had inadvertently been subjected to sterilization process. Results While withdrawing the soft-tipped extrusion cannula from the eye, following internal drainage of transvitreal and subretinal fluid, the loose silicone sleeve probably got entangled at the inner lip of the sclerotomy and finally fell on the retinal surface. In both cases, the silicone sleeve was held and removed with an intraocular forceps. Conclusions This rare complication has been reported in the literature only once previously. Sterilization of disposable subretinal fluid cannulas is not advisable because of the risk of dislocation of the silicone sleeve into the eye. Besides this, it is important to check the integrity of the silicone sleeve before and after surgery.

Abstract
BACKGROUND AND OBJECTIVES Few studies have addressed cutaneous recurrence of melanoma. The aim of this retrospective study was to analyze the characteristics and prognostic significance of the different patterns of cutaneous recurrence. MATERIAL AND METHODS Patients diagnosed with melanoma between 1988 and 2008 at Hospital de Bellvitge, Barcelona, Spain and for whom data were available for at least 2 years of follow-up were included in the study. Local recurrence was defined as melanoma invasion of the skin adjacent to the scar left by excision of the primary tumor, regional metastasis or recurrence as metastasis restricted to the area drained by a regional lymph node station, and distant cutaneous metastasis as metastasis occurring outside this area. The relationship between cutaneous recurrence pattern and age, sex, primary tumor site, tumor subtype, Breslow depth, and ulceration was assessed. RESULTS Eighty-five out of 1,080 patients (7.87%) had cutaneous recurrence. In 71 of those patients (83.53%; 27 men and 44 women; mean age, 60.68 years), this was the first indication of melanoma recurrence. Thirty-two patients had local recurrence, 32 regional metastasis, and 7 distant metastasis. Significant differences were observed in survival time from diagnosis of the primary tumor (P=.044) and from diagnosis of cutaneous recurrence (P<.001) according to the type of recurrence. CONCLUSIONS Our results suggest that the pattern of cutaneous recurrence is prognostically significant and related to the site of the primary tumor given that the majority of local and regional recurrences occurred in primary tumors located on the lower limbs and head.

Abstract
BACKGROUND To determine the efficacy and safety of intravitreal Avastin (bevacizumab) in the treatment of choroidal neovascularisation (CNV) secondary to pathological myopia (PM). METHODS This paper reports on a consecutive prospective study of patients with CNV secondary to PM who were treated with intravitreal bevacizumab (1.25 mg/0.05 ml). Patients underwent complete ophthalmic evaluation, which included best-corrected visual acuity testing measured with Early Treatment Diabetic Retinopathy Study charts, optical coherence tomography (OCT), and fluorescein angiography. RESULTS There were 17 eyes of 17 patients, and the mean age was 55.4 (SD 10.0) years. At the 6-month follow-up, the mean visual acuity improved by 8.4 letters (p = 0.04). Forty-one per cent of patients increased at least one line, and 17% increased more than six lines. There were no cases of moderate vision loss (>or=3 lines) or severe vision loss (>or=6 lines). The mean OCT foveal thickness decreased by 79.6 mum (p = 0.002). Favourable outcomes were obtained in all subgroups. Patients received an average of one injection. As a complication, there was a tear of the retinal pigment epithelium. No other ocular or systemic side effects were observed. CONCLUSION In our study, intravitreal bevacizumab appeared to be safe and efficacious in eyes with CNV secondary to PM.

Abstract
PURPOSE To study the age distribution and survival in patients with uveal melanoma. METHODS A retrospective study was performed on 303 patients diagnosed with uveal melanoma. We analysed the clinical characteristics: age, gender, tumor size and origin, follow-up time, systemic state, survival time and cause of death. RESULTS The median age of the patients was 60.09 years. The 2-, 5-, and 10-year survival of patients less than 50 years of age at diagnosis was 91.41%, 81.83% and 61.45% respectively. The 2-, 5- and 10-year survival of patients equal to or older than 50 years was 90.86%, 73.18% and 58.28% respectively. No significant difference was found between these two age groups. When we considered a possible relationship between the sex factor and survival, in patients equal to or older than 50 years of age, we found a higher survival in men than in women (log-rank test; p=0.038). CONCLUSIONS Uveal melanoma in Spain has a similar age distribution to that of other countries, and it is not an infrequent diagnosis in patients under 40 years of age. Survival rates are also similar to that of other series. We have not found any significant difference between the age of our patients and the survival, although if we analysed the subgroups, we found that the men equal to or over 50 years of age had a better survival than the women of the same age.

Abstract
PURPOSE To study the prevalence of multiple neoplasms in patients affected by uveal melanoma in Spain and to relate these with survival. METHOD We carried out a longitudinal prospective study of the prevalence of multiple neoplasms in patients diagnosed to have a uveal melanoma during the years 1984-2005. The data has been analysed for the following variables: age, sex, date of diagnosis, affected eye, origin and tumoral size, classification according to COMS (Collaborative Ocular Melanoma Study), time of follow-up, presence of other neoplasms, current clinical state, date and cause of death. RESULTS Three hundred and five patients affected by uveal melanoma have been studied in the Ocular Oncology Unit of our institution; 24 patients (7.9%) had evidence in their medical reports of one or more additional neoplasms. Excluding cutaneous neoplasms originating in basal cells, this number reduced to 22 patients (7.2%). We did not find any statistically significant differences among the presentation age, sex or localization of the melanoma (ciliary body or choroid) and the presence or absence of a second neoplasm. When we analysed the proportion of patients with metastatic disease (both alive and dead) who presented with a second neoplasm (40.9%), we found a statistically significant relationship between these variables (Chi-square test, p=0.004). CONCLUSIONS We have observed a percentage of second neoplasms similar to that described in other international studies. We did not find a larger proportion with a second neoplasm according to the sex, age, or tumoral localization, nor did we observe a higher frequency of any particular second neoplasm. We have defined a relationship between metastasic uveal melanoma, and the development of a second neoplasm, which clearly indicates a need for increased systemic follow-up in such patients.
