Microincision Vitrectomy Surgery in Vitreomacular Traction Syndrome of Retinitis Pigmentosa Patients
Figure 3
Spectral-domain optical coherence tomography (SD-OCT) of right (a) and left (b) eyes. Retinitis pigmentosa (RP) patients after mini invasive vitrectomy surgery (MIVS) with internal limiting (ILM) and epiretinal membrane (ERM) peeling. Intraretinal macular detachment and the convex lodge are disappearing. The macular thickness is reduced, particularly, the outer retinal layers and retinal pigment epithelial (RPE) are thinning and impairing. Right eye (a). There are hyperreflective dots and spots in and around the external limiting membrane (ELM), inner segment/outer segment (IS/OS) junction, and RPE. Left eye (b). The length of the preserved IS/OS junction is between the limits that correspond to the two dotted lines with hyperreflective material in the outer retinal layers (ORL) causing dome-shaped elevations. Magnified view of the border where the IS/OS line disappears. The absence of the photoreceptor integrity line outside this central zone explains the patient’s symptoms of very poor night vision and limited side vision. These elevations appear to correspond to pigment clumping seen on fundoscopy. The photoreceptor integrity line is present under the macula but fades outside the macula, a pattern characteristic of rod degeneration.
