Fundus autofluorescence in birdshot chorioretinopathy.

Koizumi H, Pozzoni MC, Spaide RF

Ophthalmology   115 ( 5 ) e15 - 20   2008年05月 [ 査読有り ]

掲載種別: 研究論文（学術雑誌）

　概要を見る

PURPOSE: To investigate the characteristics of fundus autofluorescence in birdshot chorioretinopathy (BSCR). DESIGN: Retrospective, observational case series. PARTICIPANTS: Sixteen eyes of 8 consecutive patients with BSCR (3 men, 5 women). METHODS: Color and autofluorescence photography and optical coherence tomograms of patients with BSCR seen in a referral practice were evaluated. MAIN OUTCOME MEASURES: Autofluorescent characteristics in BSCR. RESULTS: The 8 patients ranged in age from 35 to 73 years (mean, 56.9 years). Of the 16 eyes, 11 eyes (69%) of 6 patients had retinal pigment epithelium (RPE) atrophy as evidenced by hypoautofluorescent regions. Some of the hypoautofluorescent areas corresponded to the hypopigmented birdshot lesions, but the others did not necessarily show a correspondence. Eight eyes (50%) of 4 patients showed linear hypoautofluorescent streaks along the retinal vessels, most of which corresponded to visible changes at the level of the RPE. Placoid hypoautofluorescence in the macula was seen in 6 eyes (38%) of 3 patients and was correlated significantly with best-corrected visual acuity of 20/50 or less (P<0.05). CONCLUSIONS: Autofluorescence photography demonstrated the RPE atrophy, which was hard to see by other means of investigation. The areas of RPE atrophy did not necessarily correspond to the hypopigmented lesions, which suggested that both the choroid and the RPE can be affected independently. Retinal pigment epithelium atrophy in the macula may be an important cause of poor central visual acuity in eyes with BSCR.

3d spectral optical coherence tomography documentation of a retinal vein occlusion associated with a pigment epithelial detachment.

Reddy S, Koizumi H, Peralta R, Freund KB

Retinal cases & brief reports   2 ( 2 ) 99 - 100   2008年 [ 査読有り ]

掲載種別: 研究論文（学術雑誌）

　概要を見る

PURPOSE: To describe a case of a pigment epithelial detachment (PED) that likely led to a branch retinal vein occlusion (BRVO). METHODS: Color photography, fluorescein angiography, and three-dimensional spectral optical coherence tomography (3D-spectral OCT) were performed. RESULTS: Fluorescein angiography identified a PED at the site of a BRVO, and 3D-spectral OCT illustrated compression and distortion of the overlying retina at the location of the venous obstruction. CONCLUSION: It is well known that retinal arterial disease can compress an underlying vein and lead to a BRVO. A theoretically possible, but previously unrecognized cause of a BRVO is compression of an overlying vein by an underlying PED. Our case reminds us to continue to explore local anatomical factors in addition to systemic factors in patients with venous occlusive disease.

Indocyanine green angiography in eyes with substantially increased subretinal fluid 1 week after photodynamic therapy.

Koizumi H, Iida T, Nagayama D, Saito M, Sekiryu T

Retinal cases & brief reports   2 ( 1 ) 12 - 14   2008年 [ 査読有り ]

掲載種別: 研究論文（学術雑誌）

　概要を見る

PURPOSE: To investigate the characteristics of eyes in which a serous retinal detachment became substantially more extensive and persisted 1 week after photodynamic therapy (PDT) using indocyanine green (ICG) angiography. DESIGN: Retrospective, interventional case series. PATIENTS AND METHODS: The authors reviewed the ICG angiograms of five eyes of five patients with neovascular age-related macular degeneration. RESULTS: In all eyes, the ICG angiograms obtained 1 week after PDT showed a well-demarcated hypofluorescent area corresponding to the treatment spot. Vascular hyperpermeability emanating from the middle and large choroidal vessels was seen within the hypofluorescent area whether the targeted choroidal neovascularization was perfused or not. CONCLUSIONS: Choroidal vascular hyperpermeability on ICG angiography is a common finding in eyes with substantially increased subretinal fluid 1 week after PDT. PDT might even affect the middle and large choroidal vessels within the treatment spots under some conditions, leading to a supply of subretinal fluid and causing a persistent serous retinal detachment.

Familial bilateral macular aneurysmal telangiectasia.

Koizumi H, Rutledge BK, Yannuzzi LA

Retinal cases & brief reports   2 ( 2 ) 87 - 90   2008年 [ 査読有り ]

掲載種別: 研究論文（学術雑誌）

　概要を見る

BACKGROUND: Idiopathic macular aneurysmal telangiectasia or so-called Coats' disease is usually a unilateral retinal vascular abnormality in males. It has been rarely reported to occur bilaterally with and without associated abnormalities, and its occurrence in a familial setting is even rarer. PURPOSE: This is a report of a familial occurrence of bilateral macular aneurysmal telangiectasia or Coats' disease in a father and daughter. RESULTS: A 44-year-old woman and her father had bilateral macular angiopathy with macular telangiectasia, aneurysms, ischemia, and leakage, including lipid deposition. The clinical findings were confirmed with fluorescein angiography and optical coherence tomography. There was no history of systemic disease associated with a retinal vascular abnormality. CONCLUSION: To our knowledge, this is the first report of a familial occurrence of bilateral macular aneurysmal telangiectasia or Coats' disease in a daughter and father without associated systemic disease.
