We report a case of optic disc drusen (ODD) associated with peripapillary polypoidal choroidal vasculopathy (PCV). A 62-year-old Malay lady presented with both eye ODD and the left eye associated with peripapillary subretinal hemorrhage. Ultrasound B-scan and red-free photography confirmed the optic nerve head drusen findings bilaterally. Optical coherence tomography (OCT) of the left eye showed sharply elevated peripapillary pigment epithelial detachment with subretinal fluid. The presence of peripapillary polyps with branching vascular network in indocyanine green angiography of the left eye further confirmed the diagnosis of PCV and excluded choroidal neovascularization (CNV) secondary to ODD. Subsequently, the patient was treated with a combination of verteporfin photodynamic therapy with three monthly intravitreal ranibizumab injections. Three months after the combined treatment, OCT showed completely resolved subretinal fluid. ODD can cause compression of the subretinal vessels at the optic disc that results in retinal ischemia and release of vascular endothelial growth factor, which may trigger the development of CNV or PCV. The rarity of this combination makes it interesting to study more cases of ODD with PCV. Importantly, a thorough evaluation in distinguishing the PCV from the CNV that mimics it is crucial for early detection and prompt intervention. In this case, indocyanine green angiography (ICGA) is the diagnostic method to differentiate the PCV from CNV secondary to ODD.
Fungal infections always pose a predicament to management and prognosis. The saprophytic fungus, Trichosporon inkin commonly causes endogenous infection in immunocompromised individuals. We report a case of exogenous T. inkin endophthalmitis successfully treated with voriconazole, pars plana vitrectomy, and removal of the source of infection. A 51-year-old gentleman with suboptimal control of diabetes presented with a right painful red eye for a week after undergoing an uneventful phacoemulsification with a posterior chamber intraocular lens implant more than a month prior. He presented with intense inflammation in the right anterior chamber that did not respond to steroid challenge. Ultrasound B scan showed vitreous opacities with no loculations. The culture of vitreous humor was negative. Systemic investigations were also normal. Despite being given multiple intravitreal antibiotics, his right eye got worse. He then underwent vitrectomy and intraocular lens explantation, in which the culture of the lens grew Trichosporon Inkin. He was subsequently started on the appropriate antifungals (topical, intravitreal, and systemic) based on the minimum inhibitory concentration of the antifungal sensitivity test. The patient eventually showed significant clinical improvement, and intraocular inflammation was subsiding after six months of treatment. His best corrected visual acuity improved to 6/12 with Snellen's visual acuity chart.
