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.

　View Summary

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 [ Peer Review Accepted ]

Type of publication: Research paper (scientific journal)

　View Summary

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.
