PURPOSE: To describe photodynamic therapy (PDT) and additional indocyanine green (ICG) guided feeder vessel photocoagulation as a treatment of choroidal neovascularization (CNV) secondary to choroidal rupture in case of blunt head trauma. DESIGN: Interventional case report. METHODS: A 61-year-old woman developed subfoveal CNV originating from a choroid tear 8 years after blunt head trauma. Four sessions of PDT were applied and an additional two consecutive sessions of selective ICG-guided feeder vessel photocoagulation conducted. RESULTS: Transient reduction of leakage and closure of feeder vessels could not prevent further growth of the CNV. CONCLUSIONS: PDT reduced leakage temporarily and additional ICG-guided feeder vessel photocoagulation closed treated feeder vessel and CNV. New feeder vessel formation and growth of CNV in case of traumatic choroid rupture could not be treated effectively by these two laser treatment modalities to prevent severe deterioration of visual acuity.
Idiopathic central serous chorioretinopathy (ICSC) is a disease that typically affects middleaged adults and involves the sensory retina, the retinal pigment epithelium (RPE) and the choroid. Patients usually have mild visual loss. ICSC generally resolves without therapy, although the disease can become chronic with ensuing RPE decompensation. Some patients, particularly older adults, can also develop choroidal subretinal neovascularisations (CNV), which may lead to a severe loss in visual acuity. Although the aetiopathogenesis of the disease is still incompletely understood, a correlation with psychophysical stress supports the idea that the disease may be "adrenergically conditioned", leading to the development of one or several defects in the RPE, with subsequent focal leakage of serous fluid and its retention in the subretinal space. An association between ICSC and the Helicobacter pylori (HP) infection has also been recently documented, suggesting that this organism may possibly be involved in the development of some cases of ICSC. Pathogenetic mechanisms that may explain the contribution of HP in the development of ICSC are postulated.
