Abstract
PURPOSE The present study aims to assess the agreement between clinical and pathological diagnosis in conjunctival tumours in a specialist ocular oncology unit. METHODS retrospective study of consecutive patients with conjunctival tumours diagnosed at the Ocular Oncology Unit of the University Hospital of Valladolid was performed from 1992 to 2017. Tumours were classified according to their origin (epithelial, melanocytic, lymphoid and others) and degree of malignancy (benign, premalignant, malignant). A biopsy was performed in cases of symptomatic or growing lesions. Cohen´s kappa (κ) statistics was used as an indicator of agreement between clinical and pathological diagnosis. RESULTS Of 462 consecutive patients, a biopsy was required in 195 (42.2%). The agreement with the pathological diagnosis was successful in 154 (79.0%) cases. Analysis according to the grade of malignancy showed the lowest rate of agreement among benign (n = 83; 91.6%) and premalignant (n = 62; 90.3%) lesions, with a total agreement in malignant lesions (n = 50; 100%); the Cohen´s kappa coefficient (κ) was 0.90. The highest rates of concordance were found in epithelial, melanocytic and soft tissue lesions with κ values of 1, 0.8 and 1 respectively. The worst rate of concordance was found in lymphoid lesions with a κ value of 0.3. CONCLUSION Most of the conjunctival tumours were correctly identified clinically; benign and malignant lesions showed the highest rate of accuracy; however, premalignant tumours can hide micro-invasive diseases that can go unnoticed on clinical examination. The biopsy is essential for accurate diagnosis and treatment.

Abstract
ABSTRACT Descemet membrane (DM) endothelial keratoplasty is considered the gold standard for treating corneal endothelial decompensation and is a true like-for-like replacement. Not all causes of endothelial dysfunction are global, with conditions such as viral endotheliitis affecting discrete populations of endothelial cells. In this study, endothelial grafts matching the area of dysfunction were produced to preserve healthy host cells and limit the immunological burden of new grafts. We have termed this modified DM endothelial keratoplasty procedure DM endothelial patching.

Abstract
Uveitis accounts for up to 20% of blindness in Europe, making the development of new non-invasive biomarkers which could help in its management a field of interest. It has been hypothesised that tear levels of cytokines and chemokines could be used as a potential biomarker in patients with anterior uveitis, and this could be correlated with their concentration in plasma. Therefore, we measured twelve cytokines/chemokines in tear and plasma samples of 22 patients diagnosed with active anterior uveitis. Levels of these molecules in tears and plasma were compared and associated with the degree of activity of the uveitis. It is notable that the percentage of tear interleukin (IL)-6 detection was significantly reduced in the inactive phase (p < 0.05). However, the tear concentration in epidermal growth factor (EGF), fractalkine, IL-8, IL-1RA, interferon-inducible protein (IP)-10/CXCL10, vascular endothelial growth factor (VEGF) and IL-6, comparing the active and inactive period, was not statistically different. Apart from the tear VEGF levels, the cytokine/chemokine concentration in tears in the active/inactive phase was statistically different (p < 0.05) from the counterpart levels in plasma. In conclusion, no isolated cytokine/chemokine in the tears has been found in a concentration which could be used as a potential biomarker of disease activity and treatment response.

Abstract
Sarcoidosis is a chronic multisystemic disease, which can be rarely associated with autoimmune disorders, such as antiphospholipid syndrome (APS). Although amaurosis fugax is an uncommon complication, its presentation can unmask a carotid artery dissection (CAD) in these diseases. In addition, central serous chorioretinopathy (CSC) has been related to vascular disorders too. We presented a case of a Caucasian middle-aged man, who developed CAD symptoms, such as amaurosis fugax in the right eye (RE) and headache. His medical history included arterial hypertension, hypothyroidism, and Lofgren’s syndrome. On examination, retinal pigment epithelium (RPE) atrophy and subretinal fluid (SRF) in the macular area of the RE were observed. These findings were confirmed by optical coherence tomography (OCT), which also revealed an increase in choroidal thickness. However, these differed significantly from the contralateral eye. These clinical symptoms and imaging findings suggested a CSC in the RE, but not all clinical processes were justified. Subsequently, a CT angiography was performed and confirmed a significant occlusion in the right internal carotid artery and progressive sharpening of the lumen with an intimal flap due to a carotid dissection. In addition, the laboratory results were compatible with antiphospholipid syndrome (APS). To the authors’ knowledge, the patient returned to the ED due to an anterior uveitis and he is currently asymptomatic with Cemidon and Adalimumab treatment. We described for the first time a case of carotid dissection and central serous chorioretinopathy in the context of two autoimmune-based pathologies, such as sarcoidosis and antiphospholipid syndrome. Abbreviations: APS = Antiphospholipid syndrome, BCVA = Best-corrected visual acuity, CAD = Carotid artery dissection, CNV = Choroidal neovascular membrane, CSC = Central serous chorioretinopathy, CT = Computed tomography, ED = Emergency Department, ICAD = Internal carotid artery dissection, LE = Left eye, OCT = Optical coherence tomography, RAPD = Relative afferent pupillary defect, RPE = Retinal pigment epithelium, RE = Right eye, SRF = Subretinal fluid

Abstract
UNLABELLED *Correspondence - Luis García-Onrubia: luis.garciaonrubia@gstt.nhs.uk PURPOSE: To describe a novel technique for deep anterior lamellar keratoplasty (DALK) in patients central corneal perforation and deep scarring making conventional DALK (Melles or Big Bubble) unviable. A posterior Descemet's membrane (DM) skirt has provided an adequate scaffold for the migration of the host endothelial cells. METHODS AND ANALYSIS A case report. A 32-year-old male with previous hydrops developed severe corneal scarring with a break in DM visible on OCT scanning. A modified DALK procedure was perform consisting of a 400µm, 8.5mm Anterior lamellar cap with a 4.5mm posterior lamellar disc, denuded of endothelial cells and containing a DM skirt.Initially, manual dissection of the and anterior 400µm of corneal stroma was performed using a modified Melles technique. The residual posterior lamellar was assessed and found to have significant residual scarring. A central 4mm optical window was performed through the posterior lamellar over the visual axis.The donor tissue was cut using a 350µm microkeratome head. The anterior cap was trephined to 8.5mm and set aside. The posterior lamellar was placed in a punch block, and the endothelial was removed using a silicone tipped cannula. The removal of endothelial cells was confirmed using trypan blue dye. A posterior lamellar graft with a 4.0mm stromal bed and a 4.5mm DM skirt was fashion using a peeling and double punch technique. The posterior lamellar graft was inserted into the optical window such that the DM skirt provided a bridge to the donor corneal endothelium. The anterior cap was sutured with a double continuous suture of 10-0 monofilament nylon. An inferior peripheral iridotomy was created, and an air bubble filling the anterior chamber was left at the end of the case. RESULTS The preoperative visual acuity (VA) was hand movements. Full attachment of the posterior lamellar was seen at all time-points from week one onwards. Central corneal pachymetry continued to reduce for 12 weeks. One year after the operation, with sutures in, the best spectacle-corrected VA was 6/12. The corneal graft was clear, and no rejection episodes occurred. Endothelial cell repopulation of the donor DM could be observed with specular microscopy. CONCLUSION The presence of DM promotes endothelial migration and healing. Modifications to traditional DALK surgery, in which DM is used to promote endothelial healing, are a viable alternative to penetrating keratoplasty. This method eliminates the risk of allograft endothelial rejection and allows a 'regenerative' for DALK to be used, offering a new modality of treatment in patients with healthy reserves of endothelial cells and deep posterior lamellar scarring.

Abstract
UNLABELLED *Correspondence - Luis García-Onrubia: luis.garciaonrubia@gstt.nhs.uk OBJECTIVE: To report the clinical outcomes of a series of cases in which localised areas of endothelial function were selectively treated with shape and position matched endothelial transplanted in a procedure we have termed Descemet's membrane endothelial patching (DMEP). METHODS Interventional case series. Five patients presented with localised endothelial dysfunction in eyes with high-risk graft failure due either to rejection, recurrence of the focal endothelial dysfunction or because extended treatment with steroid drops was contraindicated. Endothelial grafts matching the area of dysfunction were produced to preserve healthy host cells and limit the immunological burden of new grafts. Patient demographic details, indication for surgery, preoperative and postoperative visual acuity, intraoperative and postoperative complications, and graft rejections episodes were noted. RESULTS Five patients were included in this cases series. Indications for DMEP were Fuchs' heterochromic iridocyclitis (n=1), Fuchs' endothelial dystrophy (n=2), endotheliitis (n=2). In all cases, a customised DMEP graft was used, as opposed to our standard 8.25mm circular DMEK graft size. The DMEP grafts were centred over the area of focal endothelial dysfunction. In all cases, complete graft attachment was achieved, and the corneas were cleared. Steroid drops were reduced rapidly without any episodes of graft rejection/failure reported at 1 year. CONCLUSION DMEP transplants are a viable option to treat localised endothelial dysfunction. Placing non-circular, no central transplants is surgically feasible and does not appear to affect graft adhesion. Limiting the size of the transplant may limit the immunological burden of new grafts and reduce the need for extended courses of steroids.

Abstract
The case is presented of a girl diagnosed with obstructive hydrocephalus due to pilomyxoid astrocytoma, which required a ventriculoperitoneal shunt (VPS) at the age of 5 years and 10 months. Two months later, magnetic resonance imaging of the brain did not show ventriculomegaly or other signs of increased intracranial pressure. At the age of 6 years and 2 months, a rapid onset of bilateral visual acuity loss developed and she was diagnosed with slit ventricle syndrome. Despite valve revisions of the VPS, she developed an abrupt decline of visual acuity to hand motion at 10 cm. Fundus examination revealed bilateral optic atrophy. She did not report any other systemic symptoms suggesting increased intracranial pressure, such as headache, nausea, vomiting, lethargy, irritability, or altered levels of consciousness.

Abstract
Diabetic macular oedema (DMO) is one of the leading causes of vision loss associated with diabetic retinopathy (DR). New insights in managing this condition have changed the paradigm in its treatment, with intravitreal injections of antivascular endothelial growth factor (anti-VEGF) having become the standard therapy for DMO worldwide. However, there is no single standard therapy for all patients DMO refractory to anti-VEGF treatment; thus, further investigation is still needed. The key obstacles in developing suitable therapeutics for refractory DMO lie in its complex pathophysiology; therefore, there is an opportunity for further improvements in the progress and applications of new drugs. Previous studies have indicated that Rho-associated kinase (Rho-kinase/ROCK) is an essential molecule in the pathogenesis of DMO. This is why the Rho/ROCK signalling pathway has been proposed as a possible target for new treatments. The present review focuses on the recent progress on the possible role of ROCK and its therapeutic potential in DMO. A systematic literature search was performed, covering the years 1991 to 2021, using the following keywords: "rho-Associated Kinas-es", "Diabetic Retinopathy", "Macular Edema", "Ripasudil", "Fasudil" and "Netarsudil". Better insight into the pathological role of Rho-kinase/ROCK may lead to the development of new strategies for refractory DMO treatment and prevention.

Abstract
Age-related macular degeneration (AMD) is a complex, multifactorial and progressive retinal disease affecting millions of people worldwide. In developed countries, it is the leading cause of vision loss and legal blindness among the elderly. Although the pathogenesis of AMD is still barely understood, recent studies have reported that disorders in the regulation of the extracellular matrix (ECM) play an important role in its etiopathogenesis. The dynamic metabolism of the ECM is closely regulated by matrix metalloproteinases (MMPs) and the tissue inhibitors of metalloproteinases (TIMPs). The present review focuses on the crucial processes that occur at the level of the Bruch’s membrane, with special emphasis on MMPs, TIMPs, and the polymorphisms associated with increased susceptibility to AMD development. A systematic literature search was performed, covering the years 1990–2020, using the following keywords: AMD, extracellular matrix, Bruch’s membrane, MMPs, TIMPs, and MMPs polymorphisms in AMD. In both early and advanced AMD, the pathological dynamic changes of ECM structural components are caused by the dysfunction of specific regulators and by the influence of other regulatory systems connected with both genetic and environmental factors. Better insight into the pathological role of MMP/TIMP complexes may lead to the development of new strategies for AMD treatment and prevention.

Abstract
Optic disc pit (ODP) is a rare congenital optic nerve head abnormality, which can be complicated by intraretinal and subretinal fluid at the macula (ODP-maculopathy) with progressive visual loss. The source of this fluid remains unclear and the most dominant hypotheses have pointed to vitreous cavity or cerebrospinal fluid. Although spontaneous resolution has been reported, the majority of untreated cases of ODP-maculopathy result in final visual acuity less than 20/200 or worse. A wide array of interventions, either individually or in combination with adjuvant treatments, have been tried with varying degrees of success. Recently, different surgical procedures to fill the ODP by self-sealing materials in combination with pars plana vitrectomy have been reported as an effective adjuvant treatment. However, given the relative rarity of this condition, the majority of reports describe a small retrospective case series, making it difficult to compare among different treatments options and create a consensus regarding the optimal treatment for ODP-maculopathy. In this situation, a mini-review about surgical treatment modalities and their results can be a useful approach to identify the most effective surgical option in the management of ODP-maculopathy.
