The emergence of Optical Coherence Tomography (OCT) in recent times has revolutionized the best way we see the retina. delivering, in genuine time, high-resolution cross-sectional photos of the macula which are similar to acquiring in vivo histopathological specimens, OCT represents a tremendous improve within the diagnostics of retinal disorder. the buzz of operating with this new software has been dampened by means of the non-availability of any commonplace textbook at the topic and intended that each new discovering at the OCT observed us speeding to the library nearly each day to find any released experiences at the topic. until eventually now.
Containing approximately 900 scans of either common and diseased appearances, so much in complete colour, Atlas of Optical Coherence Tomography of Macular illnesses covers find out how to use Stratus OCT for diagnosing a number of macular problems, settling on right healing ways and tracking the responses to cures and interventions. The authors supply short case summaries, fundus images, fluorescein angiography, and the OCT photos and the persist with up photographs. They speak about OCT purposes for analysis, administration, and follow-up in diabetic macular edema, macular gap, taut posterior hyaloid membrane, vitreofoveal traction, idiopathic significant serous chorioretinoplasty, submacular pathology, and extra.

This case illustrates that diabetic macular edema is multifactorial in etiology and all the aspects need to taken care of in the management of these patients. tractional foveal detachment and TPHM either alone or in conjunction with patterns 2 and 3 constitute an indication for surgical intervention. Am J Ophthalmol 2003; 135:169–77. Retina 2002; 22:759–67. Ophthalmology 1998; 105:360–70. 1999 127:688–93. e. The hyperfluorescent dot increases in the late phase with diffusion of the dye. Smockstack sign: In less than 10% of the cases, the dye streams upward to form umbrella pattern of fluorescein staining.
In addition, OCT is also able to diagnose macular traction, taut posterior hyloid membrane, serous detachment under the fovea and lamellar macular holes in these eyes. Taut posterior hyloid membrane. The quantification makes it easier to monitor the response to therapy. , cystoid macular edema and subfoveal serous detachment were relative indications where PPV was indicated only if the cystoid or edema serous detachment was a result of coexisting mechanical traction. Following series of cases illustrate as to how OCT in addition to the fluorescein angiography helped us in the management of CSME patients.
The circinate rings of hard exudates (arrows) were seen as hyperreflective lesions within the retinal layers with shadowing effect. Fluorescein angiography (B) revealed microaneurysms with late leakage consistent with macular edema. The hyperreflective shadows seen within the retinal layers (arrows) were from hard exudates. Large cystoid spaces involving variable depth of the retina with intervening septae: The cystoid spaces are initially confined to the outer retina mainly, but in long standing cases, these cysts fuse to involve almost entire length of the retina.
