Background The COVID-19 pandemic halted non-emergency surgery across Scotland. Measures to mitigate the risks of transmitting COVID-19 are creating significant challenges to restarting all surgical services safely. We describe the development of a risk stratification tool to prioritise patients for cataract surgery taking account both specific risk factors for poor outcome from COVID-19 infection as well as surgical ‘need’. In addition we report the demographics and comorbidities of patients on our waiting list. Methods A prospective case review of electronic records was performed. A risk stratification tool was developed based on review of available literature on systemic risk factors for poor outcome from COVID-19 infection as well as a surgical ‘need’ score. Scores derived from the tool were used to generate 6 risk profile groups to allow prioritised allocation of surgery. Results There were 744 patients awaiting cataract surgery of which 66 (8.9 %) patients were ‘shielding’. One hundred and thirty-two (19.5 %) patients had no systemic comorbidities, 218 (32.1 %) patients had 1 relevant systemic comorbidity and 316 (46.5 %) patients had 2 or more comorbidities. Five hundred and ninety patients (88.7 %) did not have significant ocular comorbidities. Using the risk stratification tool, 171 (23 %) patients were allocated in the highest 3 priority stages. Given an aging cohort with associated increase in number of systemic comorbidities, the majority of patients were in the lower priority stages 4 to 6. Conclusions COVID-19 has created an urgent challenge to deal safely with cataract surgery waiting lists. This has driven the need for a prompt and pragmatic change to the way we assess risks and benefits of a previously regarded as low-risk intervention. This is further complicated by the majority of patients awaiting cataract surgery being elderly with comorbidities and at higher risk of mortality related to COVID-19. We present a pragmatic method of risk stratifying patients on waiting lists, blending an evidence-based objective assessment of risk and patient need combined with an element of shared decision-making. This has facilitated safe and successful restarting of our cataract service.
IntroductionPostoperative eccentric macular hole formation is an uncommon complication after pars plana vitrectomy (PPV) without internal limiting membrane (ILM) peeling for the treatment of epiretinal membrane (ERM). We present a case of eccentric macular hole formation after PPV for ERM without ILM peeling.Case reportA 68-year-old male patient presented with ERM and visual acuity of 6/24 in his left eye. He underwent 23-gauge PPV without ILM peeling for treatment of ERM. One week postoperatively the retina was attached and the epiretinal membrane was successfully removed, while visual acuity was 6/9. One month after PPV, a single eccentric retinal hole below the macula was detected using fundoscopy and subsequently confirmed by optical coherence tomography. At this time the visual acuity was 6/9 and the patient reported no symptoms. No further intervention was attempted and at the 9-month follow-up, the visual acuity and the size of the eccentric macular hole remained stable.ConclusionEccentric macular holes can be developed after PPV even without ILM peeling and are usually managed conservatively by observation.
Purpose: The purpose of this case report was to present the clinical data and management of a 69-year-old female patient with chorioretinal folds who developed chronic central serous chorioretinopathy-like maculopathy. Case Presentation: A 69-year-old female patient presented with a recent-onset slight decrease in visual acuity in her left eye. Her past ocular history was clear. Regarding her medical history, she had only hypertension, treated with per os medications. The patient underwent a complete ophthalmological examination. At presentation, the visual acuity was 6/6 in the right eye and 6/7.5 in the left eye. Intraocular pressure was 16 mm Ηg in both eyes. On fundoscopy, chorioretinal folds were noticed in the left eye. Spectral-domain optical coherence tomography, fluorescein angiography, and indocyanine green angiography confirmed the diagnosis of chronic central serous chorioretinopathy-like maculopathy in the left eye, since other causes of chorioretinal folding were excluded. The right eye was normal. No treatment was given to the patient, and at the 6-month follow-up there was improvement in visual acuity, which was 6/6, and decreased subretinal fluid. Conclusions: Central serous chorioretinopathy-like maculopathy should be taken into account for the differential diagnosis of patients with chorioretinal folds.
Purpose To describe and compare 1. the changes in intraretinal microstructure using serial spectral domain optical coherence tomography (SD‐OCT) preceding and following pars plana vitrectomy and delamination of fibrovascular membranes and 2. Intraoperative and postoperative complications in patients with proliferative diabetic retinopathy (PDR) who had preoperative Avastin (group A) or not (group B). Methods This retrospective, interventional case series includes 113 eyes. Outcome measures included LogMAR distance best‐corrected visual acuity (BCVA), SD‐OCT integrity of photoreceptor inner and outer segments junction (IS/OS), and integrity of external limiting membrane (ELM), intraoperative and postoperative complications. Results Pre‐operative central macular thickness (CMT) was significantly correlated with the final post‐operative LogMAR BCVA in group A. Both groups were also categorised into three sub‐groups based on post‐operative IS/OS integrity (group 0: IS/OS intact; group 1: IS/OS irregular but not completely disrupted; group 2: IS/OS completely disrupted). Mean BCVA improved significantly and IS/OS integrity and ELM integrity postoperatively, were significantly and positively correlated with final BCVA in group A. Intraoperative complications such as iatrogenic tears and haemorrhage and postoperative such as vitreous haemorrhage and neovascular glaucoma where significantly less in group A compared to group B. Conclusions Pre‐operative Avastin reduces the risk of intraoperative and postoperative complications and results in better postoperative anatomic and functional outcomes in fibrovascular delamination surgery for patients with PDR.
