Cited in Scopus: 1Choroidal macrovessel (CM) is a rare, mostly unilateral vascular anomaly of the choroidal circulation.1 These abnormally large vessels may cause disturbances in the overlying retinal pigment epithelium (RPE) and the development of subretinal fluid. Some CMs can even masquerade as a choroidal tumour or parasitic infestation.1–3 Reports showing early filling of CMs during indocyanine green angiography (ICGA) suggest that most CMs are arterial in nature.1,3,4 The short posterior ciliary circulation is comprised of a medial and lateral posterior choroidal artery (PCA)5,6; the latter may represent the origin of most CMs and may explain why almost all previously reported CMs arise in the macula. - Correspondence

Cited in Scopus: 0Mucolipidosis type IV (MPS-IV, OMIM #252650), a lysosomal storage disorder caused by dysfunctional mucolipin-1, is characterized by neurologic and visual impairment, developmental delay, and achlorhydria. MCOLN1 gene mutation identification is diagnostic but requires clinical suspicion. The latter is challenging, however, because most systemic and ocular findings are nonspecific and rarely evolve simultaneously.1 Bilateral corneal clouding is the earliest hallmark sign of MPS-IV. Unlike in other metabolic causes of corneal opacification, it is owing to preferential accumulation of abnormal material in the corneal epithelium as opposed to other corneal layers. - Correspondence

Cited in Scopus: 0Orbital cellulitis is an infection of the soft tissues lying behind the orbital septum. The etiologic agents differ across age group, but gram-positive cocci colonizing the skin and the nasopharynx, such as Staphylococcus and Streptococcus species, are most commonly identified in children. Haemophilus influenzae, a gram-negative facultative anaerobe, was frequently identified before the introduction of the Haemophilus vaccine in 1985. We report the case of a 15-year-old man who presented with a severe orbital cellulitis complicated by a subperiosteal abscess (SPA) secondary to Capnocytophaga sputigena. - Correspondence

Cited in Scopus: 1Presumed solitary circumscribed retinal astrocytic proliferation (PSCRAP) is a recently described retinal tumour that is a distinct entity from other white lesions of the retina such as astrocytic hamartoma and acquired astrocytoma.1 The exact origin of these lesions is of some debate within the literature as no histological diagnosis exists to date.2,3 These lesions are not associated with tuberous sclerosis complex or related syndromes and can be distinguished from astrocytic hamartomas with imaging. - Correspondence

Cited in Scopus: 0Retinal vein occlusion (RVO) is the second most common retinal vascular disease after diabetic retinopathy. RVO stands as one of the common causes of visual morbidity and blindness in the elderly population. RVO can be classified into central retinal vein occlusion (CRVO) and branch retinal vein occlusion (BRVO) based on the site of vascular occlusion. The incidence of BRVO is generally higher than the incidence of CRVO. Systemic hypertension, hyperlipidemia, and increased body mass index are important risk factors for BRVO in young patients,1 similar to older population. - Correspondence

Cited in Scopus: 1Loss of retinal ganglion cells (RGCs), the hallmark of glaucoma (GL), is also thought to occur in patients with Alzheimer disease (AD).1,2 Structural measures derived with optical coherence tomography have been used as proxies for RGC estimates in GL3,4 and AD,5 both independently and in comparative studies.6,7 Although optic nerve damage in GL8,9 and AD10 has been reported in postmortem tissue, quantification in the retina is limited to the use of generic techniques, such as Nissl staining in the ganglion cell layer,11,12 which label all nuclei and not specifically RGCs. - Correspondence

Cited in Scopus: 0A 14-year-old boy of Middle Eastern heritage with X-linked chronic granulomatous disease (CGD) was referred to the cornea clinic for keratoconus. He had no history of uveitis. He had been diagnosed with CGD 6 years ago after suffering pneumonia requiring broad-spectrum intravenous antibiotics. He had no significant infections since starting prophylactic antibiotics and antifungals. His mother stated that he “constantly rubs his eyes.” His mother was a CGD carrier and also had keratoconus. No other family members had CGD or keratoconus. - Correspondence
Access, an unintended consequence of virtual continuing medical education during COVID-19: a department's experience at the University of Toronto

Cited in Scopus: 5Coronavirus disease 2019 (COVID-19) has irreversibly affected the lives of millions of people globally; to control its spread, many activities including clinical care have been limited to essential services.1 Continuing medical education (CME) activities in many specialities, however, have expanded and even flourished by moving to online platforms, allowing for broader interactions across hospitals, organizations, and borders. In this perspective, we highlight what we believe is the most important benefit to come from the rise in virtual CME during the pandemic drawing from our own department's experience, namely, increased access to those who have historically been excluded from traditional CME activities. - Correspondence

Cited in Scopus: 0High-intensity interval training (HIIT) is a cardiovascular exercise strategy that combines short bursts of intense anaerobic exercise with quick recovery periods. There are significant cardiovascular, metabolic, and mental health benefits associated with HIIT.1 Furthermore, this exercise regimen is correlated with better macular and optic nerve head capillary perfusion, microvascular remodelling, and decreased size of the foveal avascular zone in the long-term.1,2
