Fulltext Herpes Zoster Ophthalmicus, Central Retinal Artery Occlusion, and Neovascular Glaucoma in an Immunocompetent Individual

Ahmad SS, Suan ALL, Alexander SM

J Ophthalmic Vis Res, 2019 3 2;14(1):97-100.
PMID: 30820294 DOI: 10.4103/jovr.jovr_65_17

Purpose: To report the unusual case of an immunocompetent individual with herpes zoster ophthalmicus who developed central retinal artery occlusion and subsequent neovascular glaucoma.
Case Report: A 40-year-old, immunocompetent patient was diagnosed with herpes zoster ophthalmicus and central retinal artery occlusion on initial presentation. Subsequently, he developed neovascular glaucoma.
Conclusion: There are a few case reports of central retinal artery occlusion developing after varicella zoster virus infection. However, a literature search found no reports of neovascular glaucoma following central retinal artery occlusion secondary to varicella zoster virus infection. The present case report indicates that neovascular glaucoma is a possible complication in such a scenario.

Endogenous fungal endophthalmitis caused by an unusual fungus poses both diagnostic and therapeutic challenges. We report a case of endogenous endophthalmitis caused by a rare mold, namely Cladosporium spp., which presented with a foveal abscess. A 52-year-old male patient who was diagnosed with rectal carcinoma presented with pain, redness, and a loss of vision in the right eye. He had been experiencing the symptoms for 1 week. The patient had undergone gastrointestinal surgery 2 weeks before experiencing the eye complaint. His best-corrected visual acuity was hand movements. Fundus examination revealed a foveal abscess of around a half-disc diameter in size that simulated retinochoroiditis with vitritis. Optical coherence tomography of the macula revealed a hyperreflective lesion in the fovea, which breached the full thickness of the fovea and extended into the preretinal space. Ocular toxoplasmosis was considered. On that basis, oral trimethoprim/sulfamethoxazole was given for 1 week, although the patient's condition worsened. A vitreous tap and an intravitreal combination of vancomycin, ceftazidime, and amphotericin B were administered twice but did not improve the patient's condition. Pars plana vitrectomy was performed and the vitreous biopsy results revealed the presence of Cladosporium spp. Intravitreal voriconazole was given three times and the foveal abscess resolved into a scar. Endophthalmitis caused by Cladosporium spp. is uncommon and published case reports are extremely limited. The present case may provide insight into the variable presentation of fungal endophthalmitis and, therefore, assist with the early diagnosis and appropriate management of the condition.
