Reflections on current intravitreal therapies
Overall, about 10% of patients in a study in The Netherlands were classified as non-responders to any anti-VEGF therapy. Inadequate response to anti-VEGF therapy is described by the Royal College of Ophthalmology as the presence of fluid in any compartment after a three-month loading phase. In the CATT trial, persistence of intra-retinal fluid at greater than 80% of visits between month 1 and month 12 was deemed an inadequate or sub-optimal (anatomical) treatment response.
Adult strabismus management
Over the last two decades, there has been an upward trend in the incidence of adult strabismus attending strabismus clinics. In children, approximately 1% have strabismus, however, according to the American Academy of Ophthalmology’s recently published Adult Strabismus Preferred Practice Pattern, strabismus is common among adults, with an estimated incidence of 4% in people over the age of 15 years.
Case Study:
Bilateral sequential optic disc swelling evolving to a diagnosis of idiopathic intracranial hypertension
On general examination an elevated body mass index with short stature was noted. Ocular examination was remarkable for a brisk RAPD of her left eye with Snellen best corrected visual acuity (VA) 6/5 in her right eye and 6/60 left eye. Anterior segment examination of both eyes were unremarkable. Fundus exam of her left eye was significant for a grossly swollen optic nerve head, parapapillary oedema and a large star – shaped configuration of exudates radiating from the fovea. There was an associated vasculitis complicated by an inferotemporal vein occlusion with accompanying scattered retinal haemorrhages in the affected sector.
