PURPOSE This study investigated retinal hemodynamic changes associated with different pathologic features observed on fundus color and fluorescein angiography in patients with proliferative diabetic retinopathy. METHODS Retinal circulatory characteristics were investigated in 25 eyes of 23 diabetic patients with proliferative retinopathy using a combination of bidirectional laser Doppler velo...

Optic disc drusen (ODD) are benign congenital anomalies of the optic nerve characterized by calcified hyaline bodies. While superficial drusen can be diagnosed easily during fundus examination, detecting buried drusen requires the use of additional imaging methods such as B-scan ultrasonography (USG), fundus fluorescein angiography (FFA), computed tomography (CT) and fundus autofluorescence (FA...

PURPOSE We report the detection of peripheral retinal vascular abnormalities in the fellow eye with normal fundus in children with unilateral Coats' disease. METHODS The clinical records of patients diagnosed with Coats' disease were retrospectively reviewed. We recorded the subjects' characteristics and obtained fundus photography and fluorescein angiography (FA) images. The main outcome mea...

Bone marrow-derived multiple myeloma is a type of plasma cell tumor that may be associated with ocular complications. A 52-year-old male patient was admitted to our eye clinic with the complaint of sudden visual loss and a visual acuity of 20/50 in the right eye and 20/800 in the left eye. Fundus examination revealed common flame-shaped hemorrhages, venous dilatation and tortuosity, Roth spots,...

PURPOSE To describe the utility of using ultra-widefield digital fundus photography and ultra-widefield fluorescein angiography (UWFA) in the pediatric patient population to evaluate peripheral retinal pathology and to manage Coats' disease and familial exudative vitreoretinopathy (FEVR). METHODS Retrospective review of pediatric retinal patients with FEVR or Coats' disease who underwent ultr...

We present a case of a 34 year old man with recurrent branch retinal vain occlusion (BRVO). He was examined with fluorescein angiography, digital fundus photography, serological and immunological blood tests. In contrast to the common belief that BRVO in young people usually have a beneficial development, we point out an atypical case with prolonged course and tendency of permanent damage of th...

PURPOSE To describe the findings of the study of autofluorescence of the different retinal diseases included in the study. To determine in which diseases autofluorescence may be more, or just as, useful as fluorescein angiography (FAG) in terms of diagnostic information. MATERIAL AND METHODS We studied the retinal autofluorescence of 123 eyes of 93 patients, including various diseases of the ...

Solar retinopathy is a retinal injury caused by direct or indirect sun-gazing and solar eclipse observation without protection. Subtle changes in the retinal damage might not be evident on fundus photography and fluorescein angiography. A 40-year-old veteran suffered from paracentral scotoma in his left eye shortly after unprotected solar eclipse observation about 1 month earlier. His visual ac...

A 34-year-old man with history of stress presented to the emergency department with blurred vision in the left eye for the past week. There has been no vision change in his right eye. The vision acuity of the left eye was 20/100. The fundus examination revealed a localized serous detachment of the macula (A). The fluorescein angiography (B) and the ocular coherence tomography (OCT) (C) confirme...

BACKGROUND To report an Asian patient with branch retinal vein occlusion secondary to neurofibromatosis 1. CASE A 64-year-old woman presented with a loss of vision in her right eye of 9-month duration. A diagnosis of neurofibromatosis 1 was made. A general medical examination showed no abnormalities except the signs of neurofibromatosis 1. OBSERVATIONS Fundus examination of the right eye re...
