Purtscher's retinopathy is characterized by sudden visual loss in severely traumatized patients and is associated with multiple areas of superficial retinal whitening located primarily in the posterior pole. Visual outcome in Purtscher's retinopathy is variable, and there is no well-defined treatment. We report on a patient with immediate blurred vision in the right eye after a traffic accident. Ophthalmoscopy revealed multiple whitish patches scattered over the macular and peripapillary areas in the right eye. Fluorescein angiography showed multifocal retinal arteriolar occlusion in the early phase and staining of the involved retinal vessels and optic nerve head in the late phase. Indocyanine green angiography (ICG) showed rarefaction of choroidal vessels in the peripapillary area of the right eye at early phase. The late phase ICG study revealed multifocal hypofluorescent patches in the macular and peripapillary areas. Megadose steroid therapy was given with good visual response in the first 2 weeks, and the patient's vision had recovered completely when followed-up 10 months later.

In 1990, Yannuzzi et al. introduced a new clinical entity, "idiopathic polypoidal choroidal vasculopathy" (IPCV). There is now a more-widespread worldwide recognition of a higher prevalence and importance of this disorder. We report on the first case of IPCV in Taiwan to our knowledge. A 63-year-old Taiwanese man complained of blurred vision in his right eye for 6 months. The anterior segment and vitreous were normal except for mild nuclear cataract changes. Fundus examination of the right eye showed hard exudates and multiple reddish-orange subretinal lesions in the macula. Fundus examination of the left eye was normal. Fluorescein angiography of the right eye showed multiple hyperfluorescent granular lesions in the macula. Subretinal leakage and pooling of fluorescein were present in the temporal macula. Indocyanine green angiography disclosed multiple aneurysmal dilations at the terminals of branching vascular networks. A hyperfluorescent aneurysmal lesion corresponding to the reddish-orange nodule was observed ophthalmoscopically, and a granular lesion was observed in fluorescein angiography. Focal retinal photocoagulation was applied to the leakage area identified with fluorescein angiography. Two months after photocoagulation was performed, the subretinal fluid had gradually resolved, but a new leakage in the macula was demonstrated with fluorescein angiography. His best corrected vision in the right eye was stable.

A 48-year-old woman presented with blurred vision in her right eye for 6 weeks. Visual acuity was 20/300 and 20/25 in the right and left eyes, respectively. Fundus examination showed subretinal hemorrhage in the superonasal macula in the right eye, whereas the left eye was normal. Fluorescein angiography showed blocked fluorescence from hemorrhage and a round distinct hypofluorescent spot along the inferotemporal arcade. Indocyanine green angiography revealed hyperfluorescent tubular and aneurysmal dilatations consistent with polypoidal choroidal vasculopathy in the superior macula. Spectral-domain optical coherence tomography showed retinal pigment epithelial irregularities and detachment. Scans through the round area of hypofluorescence revealed a conforming focal choroidal excavation and thinning of the underlying choriocapillaries. Because the pathogenesis of focal choroidal excavation is currently unclear, the authors propose the possibility of an acquired etiology related to loss of choriocapillaries from perfusion abnormalities as evidenced here.
