lar thickness using optical coherence tomography (OCT) in macular edema associated with various retinal vascular disorders. ME T H O D S. This prospective nonrandomized clinical interventional study included 81 eyes (76 patients) comprised of Group I, 57 eyes (51 patients) with diabetic macular edema; Group II, 10 eyes (10 patients) with branch retinal vein occlusion; and Group III, 13 eyes (13...

AIMS To evaluate the ocular axial length as a risk factor for development of central retinal vein occlusion (CRVO) and branch retinal vein occlusion (BRVO). METHODS Ocular axial lengths were measured, by A-scan ultrasonography, in 17 patients with CRVO and 41 patients with BRVO and compared with those of contralateral unaffected eyes and 66 age matched controls. RESULTS In 17 patients with ...

years; range 41-77 years. There were 16 (35.6%) male patients and 29(64.4%) female patients. Thirty-eight (84.4%) patients (40 eyes) had central retinal vein occlusion (CRVO), 7 (15.6%) patients (8 eyes) had branch vein occlusion (BRVO), and 29 (60.4%) eyes (all CRVO) had ischaemic vein occlusion. Twenty-eight (58.3%) eyes were blind, while 18 (37.5%) had visual impairment. Twenty-five (55.6%) ...

Retinal vein occlusion is the second most common cause of visual loss due to retinal vascular disease after diabetic retinopathy.1 Among the risk factors described, it is well known that the hypercoagulable state present in neoplasias can culminate in vein occlusion. It is described that any ocular structure may be involved in acute leukemia2; involvement of the choroid and retina is the most c...

BACKGROUND/AIM Retinal vein occlusion (RVO) is one of the most frequent ocular vascular diseases and leads to severe vision impairment. Colour Doppler imaging (CDI) is the first method which allows distinct evaluation of arterial and venous velocities in RVO. CDI is valuable for diagnosis of RVO and shows the effects of isovolaemic haemodilution. Patients with RVO were monitored by CDI for 1 ye...

AIMS To investigate the predictive value of the cone b-wave implicit time in the photopic compared with the scotopic 30 Hz flicker ERG for rubeosis in central retinal vein occlusion. METHODS 44 patients with a central retinal vein occlusion were examined with full field electroretinogram (ERG). RESULTS The average implicit time in the photopic 30 Hz flicker ERG in patients who developed rub...
