Published: September 2023

Purpose: To report a case of cytomegalovirus (CMV) retinitis improved by treatment with ganciclovir in a patient with ganciclovir-resistant CMV infection associated with Good syndrome.

Study Design: Case report.

Result: A 52-year-old gentleman with Good syndrome presented with visual disturbance in his right eye. He had a history of receiving intravitreal ganciclovir treatment with CMV retinitis a year ago. During treatment for CMV colitis three months ago, in systemic blood, UL97 mutation was identified and improved after changing treatment from ganciclovir to foscarnet. CMV retinitis recurred, and intravitreal ganciclovir injection was performed but there was no improvement. Therefore, the treatment was changed to foscarnet, but retinal infiltration progressed. Accordingly, it was changed to ganciclovir again and as a result, the progression of retinitis could be stopped.

Conclusions: Even in the case of CMV retinitis, which has been genetically confirmed to be ganciclovir resistance in systemic blood, ganciclovir treatment can be considered if other anti-CMV agents are not effective.

Purpose: To investigate ocular manifestation of immune reconstitution inflammatory syndrome (IRIS) in human immunodeficiency virus (HIV) patients after starting highly active antiretroviral therapy (HAART) and its relationship to T cell immunity.

Methods: HIV patients with ocular IRIS after HAART were retrospectively reviewed. Clinical presentations with previous opportunistic infection, duration from initiation of HAART to IRIS, blood CD4+, CD8+ T cell count, and HIV RNA copies before HAART and at IRIS were analyzed.
