RESUMO
OBJECTIVE: To describe the development of a web-based data collection tool to track the management and outcomes of uveal melanoma patients. DESIGN: Description of a clinical registry. PARTICIPANTS: Patients with uveal melanoma. METHODS: A panel of expert ocular oncologists, with input from other relevant specialties and individuals with expertise in registry development, collaborated to formulate a minimum data set to be collected to track patient centred, real-world outcomes in uveal melanoma. This data set was used to create the Fight Tumour Blindness! (FTB!) registry within Save Sight Registries. RESULTS: The data set to be collected includes patient demographics and medical history, baseline visit, follow-up visit including tumour treatment, metastatic staging and surveillance, pathology, and patient-reported questionnaires. The inbuilt mechanisms to ensure efficient and complete data collection are described. CONCLUSIONS: The FTB! registry can be used to monitor outcomes for patients with uveal melanoma. It allows benchmarking of outcomes and comparisons between different clinics and countries.
RESUMO
BACKGROUND: Endophthalmitis following intravitreal injection is a potentially devastating complication of anti-VEGF injections. Post-injection endophthalmitis due to Enterococcus faecalis is rare, and no previous case of Morganella morganii endophthalmitis after intravitreal injection has been reported. CASE PRESENTATION: We present the first reported case of Morganella morganii and Enterococcus faecalis endophthalmitis after intravitreal injection in an immunocompetent patient in the absence of recent ocular surgery. Our patient presented with hand movement visual acuity one day after anti-VEGF injection and demonstrated no clinical improvement despite repeated intravitreal ceftazidime and vancomycin injections. A decision was made to proceed with early vitrectomy given failure of intravitreal antibiotics. Visual acuity improved to 6/90 at 12 weeks after vitrectomy without any evidence of disease recurrence. CONCLUSIONS: Post-injection endophthalmitis due to concurrent Morganella morganii and Enterococcus faecalis infections can have visually devastating consequences despite repeated empirical and targeted intravitreal antibiotics. Lack of clinical improvement following intravitreal antibiotics should warrant consideration of early vitrectomy. Our experience is a pertinent reminder of the ever-growing threat of uncommon and multi-resistant bacteria that must be considered when treating infections such as post-injection endophthalmitis.

BACKGROUND: The accurate encoding of operation notes is essential for activity-based funding and workforce planning. The aim of this project was to evaluate the procedural coding accuracy of vitrectomy and to develop machine learning, natural language processing (NLP) models that may assist with this task. METHODS: This retrospective cohort study involved vitrectomy operation notes between a 21-month period at the Royal Adelaide Hospital. Coding of procedures were based on the Medicare Benefits Schedule (MBS)-the Australian equivalent to the Current Procedural Terminology (CPT®) codes used in the United States. Manual encoding was conducted for all procedures and reviewed by two vitreoretinal consultants. XGBoost, random forest and logistic regression models were developed for classification experiments. A cost-based analysis was subsequently conducted. RESULTS: There were a total of 1724 procedures with individual codes performed within 617 vitrectomy operation notes totalling $1 528 086.60 after manual review. A total of 1147 (66.5%) codes were missed in the original coding that amounted to $736 539.20 (48.2%). Our XGBoost model had the highest classification accuracy (94.6%) in the multi-label classification for the five most common procedures. The XGBoost model was the most successful model in identifying operation notes with two or more missing codes with an AUC of 0.87 (95% CI 0.80-0.92). CONCLUSIONS: Machine learning has been successful in the classification of vitrectomy operation note encoding. We recommend a combined human and machine learning approach to clinical coding as automation may facilitate more accurate reimbursement and enable surgeons to prioritise higher quality clinical care.

PURPOSE: We present two atypical cases of calciphylaxis presenting with ocular ischemic pathology - both without the hallmark cutaneous manifestations - to raise awareness of this rare yet highly disabling condition. OBSERVATIONS: We report two cases of ophthalmic calciphylaxis presenting as (1) anterior ischemic optic neuropathy (AION) and cilioretinal artery occlusion in a 76-year-old woman with pre-dialysis kidney failure, and (2) AION with contralateral central retinal artery occlusion (CRAO) in a 44-year-old man on hemodialysis. CONCLUSION AND IMPORTANCE: These cases highlight the need for judicious clinical suspicion of calciphylaxis in patients with kidney failure, presenting with microvascular ischemic ophthalmic pathology such as AION or CRAO. Confirmation with temporal artery biopsy is essential to direct targeted individualized multi-disciplinary treatment of calciphylaxis and avoid unnecessary steroid exposure in cases masquerading as giant cell arteritis (GCA).
RESUMO
Surgical management of large tumors involving the conjunctival fornix can be challenging, as exposure and clear margins may be difficult to achieve. In this case series, we report our initial experience with the open book technique in 4 patients. Through a canthotomy and cantholysis, this surgical approach provides a wide surgical field and facilitates fornix reconstruction post large tumor excision. In our series, one patient had a lateral canthus dehiscence.

The authors describe the case of a 25-year-old male who presented with a cilioretinal artery occlusion secondary to posterior scleritis. The patient had a history of juvenile spondyloarthritis that evolved into ankylosing spondylitis. Cilioretinal artery occlusion is a rare complication of posterior scleritis, having only been described once previously in the literature. This is the first reported case of a cilioretinal artery occlusion in posterior scleritis that was associated with an underlying systemic disease.

PURPOSE: To analyze the single surgery success rate and anterior segment complications related to phacoemulsification and intraocular lens implantation in a series of patients undergoing phacovitrectomy for all types of primary rhegmatogenous retinal detachment. METHODS: We performed a retrospective interventional case series on 302 eyes undergoing phacovitrectomy for primary rhegmatogenous retinal detachment repair between November 1, 2016, and February 2, 2019, in Edmonton, Canada. Primary outcomes included single surgery retinal reattachment rate and anterior segment complications. Secondary outcomes included the effects of proliferative vitreoretinopathy and macula and/or peripheral internal limiting membrane peeling on the rate of surgical success. RESULTS: The single surgery success rate of phacovitrectomy for all types of primary rhegmatogenous retinal detachment was 85.1%. The presence of proliferative vitreoretinopathy was associated with lower surgical success (odds ratio, 0.33; P = 0.01). Macular internal limiting membrane peeling was associated with higher surgical success (odds ratio, 2.4; P = 0.05). Anterior segment complications included posterior capsular opacification (28.8%), posterior synechiae (10.9%), and posterior capsular rupture (2.3%). CONCLUSION: Phacovitrectomy is a safe and effective treatment option for the primary repair of rhegmatogenous retinal detachments. This study provides evidence to support the safe incorporation of phacoemulsification and intraocular lens implantation with retinal surgery.

BACKGROUND AND OBJECTIVE: Circumscribed choroidal haemangioma (CCH) has several characteristic clinical and angiographic features. We aimed to compare indocyanine green angiography (ICG) findings of CCH captured on a traditional digital camera system (DCS) to newer scanning laser ophthalmoscopy (SLO) platforms. STUDY DESIGN/MATERIALS AND METHODS: A total of 35 patients over a 10-year period diagnosed with CCH using ICG were included (18 imaged with DCS and 17 with SLO). RESULTS: On early ICG frames, intrinsic vessels were apparent in two-thirds (12/18; 67%) of the DCS group compared with all of eyes in the SLO group (p = 0.020). In addition, at maximal hyperfluorescence, most eyes imaged with DCS had a feathery appearance (16/18; 89%) compared with those in the SLO group which all (17/17; 100%) displayed a granular appearance (p < 0.001). The presence of hot spots at maximal hyperfluorescence was also more common in the SLO group (12/17; 71%) versus the DCS group (0/18; 0%) (p < 0.001). Finally, intrinsic vessels and vascular loops could be identified throughout the entire duration of the ICG in 100% of the SLO cases (17/17) versus only 11% (2/18) of DCS cases (p < 0.001). CONCLUSIONS: The visualization of intrinsic vessels, vascular loops, and "hot spots" in CCH is significantly enhanced with SLO compared with DCS. Many characteristic mid-late angiographic findings of CCH are more optimally visualized on SLO which may negate the need for late frames (>30 min) without compromising diagnostic accuracy.

Melanocytoma or hyperpigmented magnocellular nevus is a variant of melanocytic nevus that is most commonly seen in the optic nerve, but has also been reported to occur in the iris, ciliary body, choroid, sclera, and conjunctiva. We present two cases of giant uveal melanocytoma with histopathology. The first case occurred in a 10-year-old girl who presented with decreased vision in the right eye and a mushroom-shaped pigmented choroidal lesion measuring 15.5 mm in apical height. The lesion was abutting the lens but not causing a cataract. This was diagnosed as a choroidal melanocytoma on open scleral window biopsy. The second case was in a 68-year-old lady, referred for a left nasal pigmented choroidal lesion measuring 8 mm in apical height and having a mushroom configuration. The lesion grew to 8.6 mm in height and was complicated by a vitreous hemorrhage and rhegmatogenous retinal detachment and was treated with iodine-125 plaque brachytherapy. Subsequently, the treated eye became a painful phthisical eye and was enucleated. Histopathology confirmed melanocytoma with extrascleral extension but without malignant transformation. Features of melanocytoma and other very large cases reported in the literature are discussed.

This report concerns a 49-year-old female with cutaneous malignant melanoma and systemic metastases. These resolved following combination immunotherapy with ipilimumab and nivolumab. She subsequently experienced unilateral floaters, an increase in iris pigmentation and pigmentary glaucoma. The eye progressively lost vision and became painful due to iris neovascularization. The clinical diagnosis was of cutaneous melanoma metastatic to the vitreous, ciliary body and iris. Enucleation was performed for symptom control, with histopathology confirming the clinical diagnosis. The immune privilege of the eye may preclude ocular metastasis control with immunotherapy. Ocular symptoms in such patients merit referral to an ophthalmologist.

Gout is a common entity; yet it is such a great mimicker in its imaging features that it can confuse clinicians and radiologists alike, sometimes leading to unnecessary investigations and treatment. We present a case of a 52 year old male renal transplant patient who presented with a slow growing mass in his left shin. The initial radiograph demonstrated a non-aggressive looking calcified lesion. A fine needle aspiration demonstrated this lesion to be gout deposition. The lesion was unchanged in the following eight years until the patient reported a sudden growth in size. Imaging showed features of an aggressive lesion with disruption of the previous calcification as well as enhancement on magnetic resonance imaging. Surgical excision biopsy was performed in view of the worrisome features on imaging and the histology showed tophaceous gout. Following description of our case, we reviewed the clinical and imaging features of gout and discussed its differential diagnoses.

Orbital surgery is often conducted in areas with limited exposure where vital structures are tightly crowded together. A bloodless field is paramount in orbital surgery for the proper identification of normal and pathologic tissue and even minimal bleeding can obscure the surgical field, making surgery more difficult and increasing the risk of complications. Surgery for highly vascular orbital lesions is an additional situation where maintaining an adequate surgical field is often challenging but paramount. The role of the anaesthetist in controlling surgical blood loss has been increasingly recognized in the last few decades. Various techniques including hypotensive anaesthesia have been described, but the control of intraoperative bleeding does not rely on a single particular technique, but a series of well-designed interventions that result in optimal conditions. An understanding of the anaesthetic considerations pertinent to haemostasis is invaluable for oculoplastic surgeons. Additionally, with the growing use of endonasal approaches to medial wall decompression and accessing the medial orbit, it has become increasingly important that orbital surgeons understand the anaesthetic requirements of their colleagues in other disciplines.

Peritoneal lymphomatosis, a rare presentation of lymphoma, can mimic peritoneal carcinomatosis. Computed tomography findings in both conditions include omental caking, as well as peritoneal enhancement, thickening and nodularity. We report three cases of peritoneal lymphomatosis and give an analysis of the salient imaging features that aided in the accurate diagnosis of the condition in each case. Two of the three cases demonstrated elevated serum cancer antigen 125 levels, a marker commonly associated with ovarian carcinoma. It is thus critical to distinguish peritoneal lymphomatosis from carcinomatosis, as the prognosis and management are dramatically different.

There are over 300 million people living in the world today who are visually impaired and a further 45 million who are blind. The large majority (90%) of these people live in developing countries, and up to 75% of blindness are avoidable. With cataracts being the major cause of blindness and visual impairment, many ophthalmic aid programmes are aimed at alleviating the enormous burden caused by this readily treatable disease. Having said that, caution should be exercised that short surgical visits to remote rural areas that are not coordinated with local national eye care managers should be discouraged because they do little for the development of sustainable eye care programmes. With this in view, it has become imperative to design blindness prevention and ophthalmic support programmes that are workable, comprehensive, economical and sustainable.

We present an unusual case of polypoidal choroidal vasculopathy (PCV) lying above the retinal pigment epithelium (RPE) in a 60-year-old Caucasian female. PCV lesions are typically located beneath the RPE layer. However, they may rarely lie above the level of the RPE due to a discontinuity in the RPE and Bruch's membrane.

Orbitofrontal cholesterol granuloma is a rare entity that has a predilection for men in their fourth or fifth decade and occurs almost exclusively within the frontal bone overlying the lacrimal fossa. Surgery by drainage and curettage is virtually curative in all cases and recurrence is very rare. We describe the case of a 77-year-old man with recurrent orbitofrontal cholesterol granuloma 11 years after surgery, presumably due to subtotal curettage. The potential use of an endoscope to aid complete removal of lesion is discussed.

The use of endoscopic orbital and optic nerve decompression for traumatic optic neuropathy and dysthyroid orbitopathy have been well documented; however, reports on endoscopic decompression for benign orbital apex lesions are scarce. The records of two patients who underwent endoscopic decompression of the bony orbit for progressive visual loss were reviewed. Patient 1 had fibrous dysplasia and presented with headache and visual field defects. Patient 2 had sphenoid wing meningioma and multiple previous attempts of transcranial tumor resection and orbital decompression. Both had progressive visual deterioration and ultimately underwent transnasal endoscopic orbital decompression. Post-operatively, both patients had subjective and objective improvement in visual function and compressive symptoms. No complications from the endoscopic decompression were observed in both patients. Transnasal endoscopic approach may be a viable option for decompression of benign orbital apex lesions.
