Harada-like syndrome post-Covishield vaccination: A rare adverse effect

Covishield is in wide use in India with about 80% efficacy. Serious side effects are still under study. A 30-year-old female presented to us 7 days post-vaccination with a 5-day history of sudden diminution of vision in both eyes. The clinical findings were suggestive of the Vogt-Koyanagi-Harada (VKH) syndrome. She was treated with high-dose oral steroids. At this juncture, the association was unclear. However, it was justified by an acute flare-up of uveitis on day 2 post the second dose of vaccination despite ongoing steroids. A direct correlation of Harada-like syndrome with the Covishield vaccine is observed here

Progressive multifocal leukoence-phalopathy presenting as homonymous hemianopia in a patient with acquired immunodeficiency syndrome.

We present a case of a Human Immunodeficiency Virus (HIV) positive patient who was referred for retinal evaluation to rule out ophthalmic manifestations of Acquired Immunodeficiency Syndrome (AIDS). She complained of some disturbance in vision in both eyes. Fundus examination showed no abnormality. Perimetry, done to rule out optic nerve pathology, showed a left homonymous hemianopia. Magnetic Resonance Imaging (MRI) scan showed features of Progressive Multifocal Leukoencephalopathy (PML). She had no other neurological symptoms or signs.

Acute myopia and angle closure caused by topiramate, a drug used for prophylaxis of migraine.

Acute transient myopia with shallowing of the anterior chamber is a rare idiosyncratic response to many systemic and topical medications, including sulfonamides. Several such cases have been reported in the past, but are less frequently reported in recent times. We report a case of acute progressive myopia and bilateral angle closure due to Topiramate--a drug used for epilepsy and migraine prophylaxis.
