    Evaluation of Macula with Optical Coherence Tomography in Patients with Decreased Visual Acuity after Successful Retinal Detachment Surgery
    Seymenoglu, G; Sahin, BÖ; Top, CG; Kayikçioglu, Ö; Baser, E
    Purpose: To study the foveal microstructural changes that may explain the incomplete visual recovery in eyes with anatomically successful repair of rhegmatogenous retinal detachments (RRD) using spectral-domain optical coherence tomography (OCT) and to evaluate the correlation between foveal changes and postoperative visual acuity. Material and Method: Forty-four eyes of 43 patients with macula-off RRDs were examined in our study Patients were examined on first, third and sixth months postoperatively The patients had a complete ophthalmological examination and OCT images were obtained at all postoperative visits. The postoperative OCT findings were classified in 4 groups: Group 1: continuous inner segment/outer segment (IS/OS) line, Group 2: disrupted IS/OS line, Group 3: epiretinal membrane (ERM), Group 4: residual foveal detachment. Results: Postoperative OCT findings showed that group 1 consisted of 19 eyes (43.2%), group 2 consisted of 15 eyes (34.1%), group 3 consisted of 7 eyes (15.9%) and group 4 consisted of 3 eyes (6.8%). The mean best -corrected visual acuity (BCVA) was significantly higher (p<0.001). Discussion: Spectral-domain OCT provides valuable information which helps the understanding of foveal microstructural changes and explains the possible causes of poor postoperative visual acuity in eyes with anatomically successful RRD repair.

    Resolution of vitreomacular traction following intravitreal triamcinolone acetonide injection in an eye with branch retinal vein occlusion
    Seymenoglu, G; Kayikçioglu, Ö; Sahin, BÖ
    A 60-year-old woman with a past medical history of branch retinal vein occlusion presented with decreased vision and metamorphopsia in her left eye. A fundus examination revealed a tortuous retinal vein with a few retinal hemorrhages in the inferotemporal quadrant. Optical coherence tomography revealed a partially separated posterior vitreous membrane pulling up the fovea. The patient refused surgical treatment so intravitreal triamcinolone acetonide (4 mg/0.1 mL) was administered. The patient reported resolution of symptoms in her left eye following this treatment, but her visual acuity did not show any improvement. Optical coherence tomography scanning revealed a complete detachment of the posterior hyaloid with release of the vitreomacular traction. In patients with vitreomacular traction and branch retinal vein occlusion, the combination of the possible vitreous liquefaction and mechanical increase of vitreous volume caused by an intravitreal injection with a degree of reduction in retinal thickness may play a role in the resolution of vitreomacular traction.
