Restructuring emergency eye services during COVID-19 in a tertiary referral centre.

BACKGROUND/AIMS: Maintaining emergency eye services is crucial during the COVID-19 pandemic. This article describes the introduction of a new restructured referral pathway to reduce the burden on healthcare providers and create a safe environment. METHODS: During January and February 2020 (group 1), all appointments were face-to-face with a walk-in eye casualty. The first audit cycle comprised all patients in group 1. The primary audit criteria were discharge rates, referral to subspeciality and reattendance. In April 2020, a remodelled system was implemented in which walk-in attendance ceased and was replaced with telephone triage coupled with digital imaging via NHS email for remote clinical review. Patients requiring further assessment following this triage were invited in for face-to-face appointments. A reaudit was conducted during April-July 2020 (group 2) following implementation of these COVID-19 protocol changes. RESULTS: In group 1, 2868 appointments (100.0%) were face-to-face and in group 2 4870 (100.0%) appointments were telephone consults that resulted in 2639 (54.2%) face-to-face appointments. The rate of discharge in the first cycle and second cycle were 55.3% and 76.9% respectively (P<0.0001). Furthermore 2298 (47.2%) patients were able to be discharged following telephone consultation in group 2. CONCLUSIONS: Using this telephone and digital imaging review triage system, the authors have demonstrated a significant reduction in the need for face-to-face reviews. The reduction in avoidable patient face-to-face reviews allows the system to move from saturated to sustainable while increasing accessibility to services for patients who may not be able to present for face-to-face review. This complete audit cycle successfully charts interventions that maximise accessibility, reduce unnecessary hospital visits and deliver safe and prompt management during the pandemic.

Optic Disc Pit Maculopathy - Case Series, Clinical Approach, and Management.

PURPOSE: The purpose of this study was to analyze the diagnostic and therapeutic approach of five cases with optic disc pit (ODP) maculopathy. MATERIALS AND METHODS: This was a retrospective study of five patients diagnosed with ODP maculopathy. Four of these cases had unilateral involvement, whereas one case had bilateral findings. The medical notes of these individuals were reviewed in order to record the presenting symptoms, clinical signs, visual acuity (VA), imaging, management, and the final visual outcome on their last follow-up appointment. RESULTS: The first patient (53-year-old female) underwent a left pars plana vitrectomy (PPV) combined with inner retinal fenestration, endolaser, and perfluoropropane (C3F8) gas tamponade and her VA improved from 6/24 to 6/9 Snellen. A focal retinal laser treatment was carried out on our second patient leading to decrease of the subretinal fluid but had a poor visual outcome due to the underlying secondary glaucoma from iris melanoma treatment in the past. The third patient was an asymptomatic 7-year-old girl in which the maculopathy resolved spontaneously without any surgical intervention with a final VA of 6/5. The fourth and fifth patients were asymptomatic with good vision in both eyes and were, therefore, only monitored with follow-ups. CONCLUSION: ODP maculopathy remains a challenging clinical entity for a vitreoretinal surgeon. The current management for ODP maculopathy involves surgical procedures with PPV being a common treatment of choice. Spontaneous resolution of ODP maculopathy has also been reported. Our study highlights the contrasting management that can be adopted in the treatment of ODP maculopathy, and there is not one definite treatment for this condition.

Optic Disc Pit Maculopathy: A Review.

Optic disc pit (ODP) is a rare congenital anomaly of the optic disc that can be associated with maculopathy leading to progressive visual deterioration. The vast majority of cases are sporadic and no obvious factors have been correlated with the development of maculopathy. Optic disc pit maculopathy is defined by the concentration of intraretinal and subretinal fluid at the area of macula. Despite the advances in the imaging of the fundus, the origin of the fluid remains unknown and the exact pathogenesis of the maculopathy is not fully understood. Although some cases have been reported to resolve spontaneously, most cases require surgical intervention in order to treat ODP maculopathy and prevent loss of vision. Currently, there is no definite treatment for these patients and several surgical methods have been described, including pars plana vitrectomy (PPV) (combined with various techniques, such as inner retinal fenestration, autologous fibrin, and glial tissue removal), laser photocoagulation, intravitreal gas injection, and macular buckling. Overall, PPV remains the main form of surgical repair of ODP maculopathy. Although our understanding of the background and the pathophysiology of the disease has significantly improved, more studies are required in order to define the optimal treatment. This review summarizes the potential pathogenesis, as well as the diagnostic and therapeutic approach of ODP maculopathy.

A Combination of Surgical Techniques to Repair a Giant Traumatic Macular Hole.

A 38-year-old man with a traumatic full-thickness macular hole (FTMH) presented to our eye casualty department with a sudden deterioration of his right eye vision to hand movements over the past one week. The suspected traumatic FTMH was present since he was 13 years old from a direct impact of a golf ball in his right eye and his best-corrected visual acuity (BCVA) has always remained at 1/60 Snellen vision. On examination, he had a very large FTMH measuring 1635 µm with central foveal retinal detachment. Pars plana vitrectomy combined with large inverted internal limiting membrane (ILM) peel flap, 5000 Cs silicone oil tamponade, and autologous platelets implantation was performed. Follow-up visits revealed that the FTMH was closed under silicone oil. The silicone oil was removed six months after the surgery and the FTMH remained close with the retina remaining attached. His BCVA was restored to his previous baseline level of 1/60 Snellen vision. With the advent of multiple techniques to repair FTMH such as the ILM flaps, we have combined this technique with older proven techniques such as silicone oil tamponade and autologous platelets implantation to close the giant traumatic FTMH. This case study demonstrates that combining techniques can help close a FMTH that is otherwise deemed impossible in the past.

An unusual differential diagnosis of a left iliac fossa mass.

We present a case of decompensated alcoholic liver cirrhosis with widespread porto-systemic anastamoses that resulted in varices within the rectus muscle. A literature review reveals only two similar cases previously. Intramuscular varices may predispose to local haemorrhage, especially in those with underlying coagulopathy as a result of liver cirrhosis. Management options include optimising medical management of the underlying condition, simple analgesics, and for those at high risk of bleeding, decompression by transjugular intrahepatic porto-systemic shunting. Interim monitoring by ultrasonography is also helpful in detecting rapid increases in vascular size. In our case the patient continued to drink heavily and developed hepatic encephalopathy. Her prognosis remains poor and is currently a poor candidate for any surgical intervention.
