Myopic vitreomacular traction syndrome

Background: Myopic traction maculopathy [MTM], also known as myopic foveoschisis typically occurs in highly myopic eyes often leads to blindness. The pathologic features of foveoschisis may be alone or it may be associated with foveal detachment or macular hole

Aim of the work: To assess the role of vitrectomy with internal limiting membrane [ILM] peeling in changing visual outcomes and optical coherence tomography [OCT] findings of the macula in patients with myopic vitreo-macular traction syndrome

Design of the study: prospective Interventional case series

Methodology: 19 high myopic eyes of 17 patients divided into 3 groups: Group 1 [Foveoschisis only]: [6 eyes]. Group 2 [foveoschisis and foveal detachment]: [6 eyes]. Group 3 [foveoschisis, foveal detachment and macular hole]: [7 eyes]

Results: In our study, the visual acuity significantly improved in all eyes at 6 months postoperatively. This was associated with significant reduction of central foveal thickness. There was statistically significant inverse correlation between changes in best corrected visual acuity [BCVA] and both basal refraction and basal BCVA. There was statistically significant direct correlation between changes in central foveal thickness [CFT] and basal refraction. On the other hand, there was significant inverse correlation between changes in CFT and basal CFT

Conclusion: Visual improvement was better in foveoschisis with foveal detachment eyes than in foveoschisis or macular hole eyes

Recent trends in retinal and choroidal imaging

The last decade have witnessed a tremendous advancement in retinal and choroidal imaging technologies thanks to improved light sources, detectors and high speed computers which are continuously improving. There are many examples as Fundus autofluorescnce is a relatively novel imaging method that allows topographic mapping of lipofuscin distribution in the retinal pigment epithelium cell monolayer as well as of other fluorophores that may occur with disease in the outer retina and the subneurosensory space. Optical coherence tomography is a method of using low-coherence interferometry to determine the echo time delay and magnitude of backscattered light reflected off an object of interest. This method can be used to scan the retina with very high axial resolution. Optical coherence tomography angiography [OCTA] is a new non-invasive imaging technique that employs motion contrast imaging to get high-resolution volumetric blood flow information generating angiographic images in just a few seconds. OCT is undergoing another transformation with Multicolor technology by combining with confocal scanning laser ophthalmoscope t to acquire images using data from three simultaneous lasers red, green and blue taking advantage of the different wavelengths of each of these colors to image 3 different zones of the retina
