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 pictures of the macula which are similar to acquiring in vivo histopathological specimens, OCT represents an incredible boost within the diagnostics of retinal disorder. the thrill of operating with this new software has been dampened by way of the non-availability of any regular textbook at the topic and intended that each new discovering at the OCT observed us speeding to the library nearly every day to find any released experiences at the topic. till now.
Containing approximately 900 scans of either general and diseased appearances, so much in complete colour, Atlas of Optical Coherence Tomography of Macular illnesses covers easy methods to use Stratus OCT for diagnosing a variety of macular problems, opting for right healing methods and tracking the responses to cures and interventions. The authors supply short case summaries, fundus images, fluorescein angiography, and the OCT photographs and the stick with up pictures. They speak about OCT functions for analysis, administration, and follow-up in diabetic macular edema, macular gap, taut posterior hyaloid membrane, vitreofoveal traction, idiopathic important serous chorioretinoplasty, submacular pathology, and extra.

Thoroughly revised and up-to-date, this well-illustrated and practically-oriented textual content has retained its basic structure and magnificence and department into specimen-type established chapters. The visible photograph continues to be key to explaining the pathological techniques and this can be facilitated via complete color images in the course of the textual content.
The emergence of Optical Coherence Tomography (OCT) lately 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 huge boost within the diagnostics of retinal sickness.

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.
Repeat OCT showed resolution of serous fluid with return of foveal contour to normal (C). Fundus right eye showed the presence of serous fluid in the center with a linear, hypopigmented band suggestive of fibrinous exudation (A). Fluorescein angiography showed multiple areas of hyperfluorescence with hypofluorescence corresponding to fibrin (B–D). The fibrinous band was seen as hyperreflective band on OCT (not shown in the picture). The RPE at the sites of PED was a bit irregular. Based on clinical picture and fluorescein angiography, a diagnosis of ICSC was established (A, B).
Optical Coherence Tomography OCT scan at 45 degrees showed the presence of serous retinal detachment with a hyperreflective area in the center corresponding clinically to fibrinous exudation (J). The fibrin had partially resolved (K) and repeat fluorescein angiography (L) showed few areas of hyperfluorescence. Repeat OCT scan through the center of fovea (M) showed normal foveal contour with a thin hyporeflective streak under the fovea suggestive of underlying serous fluid while a vertical scan passing through the fibrin (N) showed hyperreflectivity (arrow) with underlying area of hyporeflectivity suggestive of underlying serous fluid.
