Non leaking cystoid macular edema

The current study was conducted to report the discrepancy in findings between Spectral Domain-Optical Coherence Tomography [SD-OCT] and Fundus Fluorescein Angiography [FFA] examinations of the macular area regarding Cystoid Macular Edema [CME] in patients with diabetic retinopathy [DR] or retinal vein occlusion [RVO]. This was a retrospective observational case study, involved 205 eyes of 179 patients. Eyes with diabetic retinopathy or retinal vein occlusion those underwent SD-OCT and FFAwere included in the study. All eyes had SD-OCT detected CME. In the current study, SD-OCT detected CME was associated with diabetic retinopathy in 56.1% of eyes and with retinal vein occlusion in 43.9% of eyes. CME associated with DR or RVO was undetected on FFA examination in 12.2% and 7.3% of eyes, respectively. Both SD-OCT and FFA were complementary to each other in the detection of CME in eyes with DR or RVO. The use of both SD-OCT and FFA aided in the diagnosis, the choice of the treatment option and the final visual outcome

Echographic evaluation of optic disc excavation

To evaluate the role of high resolution B-scan echography in differentiating the causes of optic disc excavation. A prospective study was conducted on 30 subjects presenting to Al-Zahraa University Hospital [2009 - 2011] with optic nerve excavation. Of these patients 10 with coloboma, 10 with cup-shaped posterior staphyloma and 10 with glaucomatous optic nerve cupping were identified. Horizontal and vertical approaches for optic disc excavations were evaluated using B-scan echography. Specific echographic criteria for excavation configurations were successfully estimated. High-resolution contact B-scan echography may provide useful differentiation for optic disc excavations in eyes with opaque media
