Unilateral Familial Exudative Vitreoretinopathy: Clinical Profile and Pathology

We report a case of a newborn with unilateral retinal detachment that could not be repaired. At examination under anesthesia, the retina was markedly abnormal and a presumptive diagnosis of retinal dysplasia was made. Several years later, the eye was enucleated because it was blind and painful. Final pathology was consistent with familial exudative vitreoretinopathy (FEVR). The literature describing unilateral retinal dysplasia is sparse. This case adds to the clinical spectrum of pathologic findings in FEVR

Mortality and pulmonary complications in patients undergoing surgery with perioperative SARS-CoV-2 infection: an international cohort study

Background: The impact of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) on postoperative recovery needs to be understood to inform clinical decision making during and after the COVID-19 pandemic. This study reports 30-day mortality and pulmonary complication rates in patients with perioperative SARS-CoV-2 infection. Methods: This international, multicentre, cohort study at 235 hospitals in 24 countries included all patients undergoing surgery who had SARS-CoV-2 infection confirmed within 7 days before or 30 days after surgery. The primary outcome measure was 30-day postoperative mortality and was assessed in all enrolled patients. The main secondary outcome measure was pulmonary complications, defined as pneumonia, acute respiratory distress syndrome, or unexpected postoperative ventilation. Findings: This analysis includes 1128 patients who had surgery between Jan 1 and March 31, 2020, of whom 835 (74·0%) had emergency surgery and 280 (24·8%) had elective surgery. SARS-CoV-2 infection was confirmed preoperatively in 294 (26·1%) patients. 30-day mortality was 23·8% (268 of 1128). Pulmonary complications occurred in 577 (51·2%) of 1128 patients; 30-day mortality in these patients was 38·0% (219 of 577), accounting for 81·7% (219 of 268) of all deaths. In adjusted analyses, 30-day mortality was associated with male sex (odds ratio 1·75 [95% CI 1·28–2·40], p\textless0·0001), age 70 years or older versus younger than 70 years (2·30 [1·65–3·22], p\textless0·0001), American Society of Anesthesiologists grades 3–5 versus grades 1–2 (2·35 [1·57–3·53], p\textless0·0001), malignant versus benign or obstetric diagnosis (1·55 [1·01–2·39], p=0·046), emergency versus elective surgery (1·67 [1·06–2·63], p=0·026), and major versus minor surgery (1·52 [1·01–2·31], p=0·047). Interpretation: Postoperative pulmonary complications occur in half of patients with perioperative SARS-CoV-2 infection and are associated with high mortality. Thresholds for surgery during the COVID-19 pandemic should be higher than during normal practice, particularly in men aged 70 years and older. Consideration should be given for postponing non-urgent procedures and promoting non-operative treatment to delay or avoid the need for surgery.

Bilateral Optic Disc Swelling in a Patient With Atypical Hemolytic Uremic Syndrome

Hemolytic uremic syndrome (HUS), most often triggered by infection with Shiga toxin producing Escherichia Coli, is characterized by microangiopathic hemolytic anemia, thrombocytopenia, and acute kidney injury. Less often, atypical HUS (aHUS) can result from dysregulation of the alternative complement pathway due to genetic mutations.1 We report a case of bilateral optic disc swelling in a patient with aHUS attributed to a mutation in thrombomodulin, which encodes a vascular endothelial glycoprotein

Chronic Progressive External Ophthalmoplegia Masquerading as Thyroid Associated Ophthalmopathy

Chronic progressive external ophthalmoplegia (CPEO) is marked by progressive bilateral ptosis and reduction in ocular motility without other systemic symptoms of mitochondrial dysfunction.1 Conversely thyroid-associated ophthalmopathy (TAO) may present with diplopia and restricted extraocular motility, but has associated eyelid retraction along with inflammatory signs including conjunctival redness, eyelid edema, and proptosis.2 We describe a case referred to oculoplastics as concern for TAO, but a diagnosis of CPEO was ultimately made
