Characteristics of the ocular fundus of Chinese patients with polypoidal choroidal vasculopathy / 中华眼底病杂志

Objective To investigate the characteristics of the ocular fundus of Chinese patients with polypoidal choroidal vasculopathy (PCV). Methods The photographs of ocular fundus of 42 Chinese patients (48 eyes) with PCV diagnosed by fundus photography, fundus fluorescein angiography (FFA), and indocyanine green angiography (ICGA) were analyzed. Results In 48 eyes with PCV, 35 (72.9%) had subretinal hemorrhage, 13 (27.1%) had yellow-white exudation, 7 (14.6%) had subretinal tuberculum-like focus in tangerine peel at the posterior pole, and 26 (54.2%) had hemorrhagic or serous pigment epithelium detachment (PED). Thirty-six eyes (75.0%) had polypoidal dilations with branching vascular network, and the other 12 (25.0%) had scattered polypoidal dilations without identifiable continuous branching vascular network. The location for these lesions were at the macular region in 30 eyes (62 5%), arcade region in 6 (12.5%), peripapillary region in 3 (6.3%), and combination region in 9 (18.8%). Conclusions Most of the lesions in Chinese patients with PCV locate at the macular region and temporal vascular arcade. Most eyes are characterized by branching choroidal vessels with polyplike terminal aneurysmal dilations in ICGA.

Polypoidal choroidal vasculopathy / 中华眼底病杂志

Objective To observe the clinical features of polypoidal choroidal vasculopathy (PCV) in Chinese patients. Methods Nine cases (9 eyes) were examined with fundus examination, fundus fluorescein angiography (FFA) and indocyanine green angiography angiography (ICGA). Results FFA and ICGA showed the branching vascular networks (7 cases) and polyplike dilation at terminals of branches (9 cases), which mainly located in macular area (8 cases) and in peripapillary area (1 case), and which accompanied hemorrhagic or serous pigment epithelial detachment in 7 cases,and 4 of 7 cases had a significant horizontal black-white damarcation line. It definitely differed from fine choroidal neo-vascularization (CNV). Conclusion PCV in Chinese patients has the cardinal clinical features, i.e., polyplike lesions located mainly in macular area and most cases accompanied by hemorrhagic or serous pigment epithelium detachment.

The Color Vision Test in Acute Central Serous Chorioretinopathy

PURPOSE: To evaluate the usefullness of color vision test for early detection of abnormal choroidal circulation of central serous chorioretinopathy (CSCR) METHODS: We investigated the color vision defect in central serous chorioreinopathy at active and resolved phase on both eyes and to identify the relation between fluorescein angiography (FAG), indocyanine green angiography (ICGA) finding and color vision defect. We examined the color vision with the Neitz anomaloscope OT-II, Farnsworth-Munsell 100-hue test, Ishihara pseudoisochromatic plate in 72 eyes of typical acute CSCR patients. We also performed ICGA in 13 eyes revealed color vision defect in fellow eye and 13 eyes not revealed color vision defect in fellow eye at resolved phase. RESULTS: Dyschromatopsia was detected in CSCR at active and resolved phase on both eyes. Most of them showed blue-yellow color defect. Location of leaking point was associated with red-green color defect in active affected eyes. Dyschromatopsia of fellow eyes at resolved phase was associated with abnormal choroidal circulation on ICGA finding. CONCLUSIONS: We suggest that color vision test, as a non-invasive screening test, might be useful for early detection of abnormal choroidal circulation of CSCR.
