Acute retinal necrosis (ARN) is known to occur in conjunction with primary varicella or chickenpox infection. The majority
of ARN cases reported in the literature were of milder form with mild to moderate vitritis, limited retinitis, and rare occurrence
of retinal breaks or detachment that responded well to intravenous acyclovir, with or without oral prednisolone. We report
a case of unilateral ARN with marked vitritis and retinal necrosis leading to retinal breaks following chickenpox in a 32-year-old
healthy lady. This patient was successfully treated with intravenous acyclovir followed by oral acyclovir and orbital floor
triamcinolone injections to contain the inflammation with barrier laser therapy to secure the retinal breaks with good visual
outcome. This case is unusual in its severity, and to our knowledge, orbital floor triamcinolone therapy was not used earlier
to contain ARN inflammation.
