Spectral domain optical coherence tomography in patients after successful management of postoperative endophthalmitis following cataract surgery by pars plana vitrectomy

Purpose. To estimate localization and the period up to the appearance of small hyperreflective round-shaped droplets using spectral-domain optical coherence tomography (SD-OCT) after pars plana vitrectomy with silicone oil tamponade.Methods. A retrospective observational study included 24 patients who had undergone pars plana vitrectomy with silicone oil tamponade for proliferative vitreoretinopathy (PVR) retinal detachment. SD-OCT analysis was performed 1, 3, and 6 months after surgery. We characterized the emulsified silicone oil in the SD-OCT as the small hyperreflective round-shaped droplets.Results. In SD-OCT examination, none of the patients had hyperreflective round-shaped droplets visible one month after vitrectomy with silicone oil tamponade. The hyperreflective droplets were found three months after surgery—in one patient above the optic nerve and in five patients intraretinally (in the cystoid spaces). Six months after vitrectomy, the hyperreflective round-shaped droplets were still present in the aforementioned patients' eyes and additionally in 3 eyes above the optic disc.Conclusions. Hyperreflective round-shaped droplets were found in a SD-OCT examination 3 months after silicone oil tamponade. The authors suggest that they are most likely the emulsified silicone oil droplets. The authors hypothesize that emulsification and migration of silicone oil begin within 3 months after surgery.

Abstract Background To evaluate changes in anterior segment morphology on anterior segment optical coherence tomography (AS-OCT) following pars plana vitrectomy (PPV) without tamponade. Methods Patients who underwent PPV without tamponade for epiretinal membrane were evaluated. Eligible patients underwent intraocular pressure (IOP) measurement and AS-OCT preoperatively as well as 1 month and 6 months post-operatively. Anterior chamber width (ACW), anterior chamber depth (ACD), trabecular iris angle (TIA), angle opening distance at 500 and 750 µm (AOD), and trabecular iris space area at 500 and 750 µm (TISA) at four quadrants were recorded and analyzed. Additionally, the mean values of TIA (MTIA), AOD (MAOD), and TISA (MTISA) for each eye (mean of four quadrants) were analyzed. Results 23 patients completed the study. The mean age of participants was 56.4 ± 3.6 years of age and 13/23 (56%) were female. Mean IOP of patients was 18.1 ± 1.1, 18.3 ± 1.1, and 18.1 ± 1.2 preoperatively,1 month post-operatively, and 6 months post-operatively, respectively. (p = 0.83). No difference was detected post-operatively in measurements of ACW, ACD, MTIA, MAOD500, MAOD750, MTISA500, and MTISA750. Conclusion Pars plana vitrectomy without tamponade was not associated with changes in anterior chamber morphology.

Aim: To demonstrate the morphological outcomes of macular hole following prophylactic peripheral laser retinopexy (PPLR). Methods: Our retrospective case-control analysis included 92 eyes, 55 in the laser group and 37 in the non-laser group. Fifty-five patients were subjected to prophylactic peripheral laser retinopexy in preparation for pars plana vitrectomy for macular hole, with and without vitreomacular adhesion (laser group). Before and after prophylactic peripheral laser retinopexy, we evaluated any changes in vitreomacular anatomy by optical coherence tomography. Optical coherence tomography changes were also analyzed in the visits preceding pars plana vitrectomy in 37 macular hole eyes not subjected to prophylactic peripheral laser retinopexy (non-laser group). Results: In the laser group, 7 out of 55 eyes (12.7%) showed macular hole closure (6 out of 18 macular hole eyes with vitreomacular adhesion (33.3%) and 1 out of 37 eyes without vitreomacular adhesion (2.7%)), while no patients showed macular hole closure in the non-laser group (p < 0.05). The mean width of the seven closed macular hole was 191.4 µm (range: 59–282 µm). In all except one of the six macular hole eyes with vitreomacular adhesion, the macular hole closed without vitreomacular adhesion release. In our analysis of the patient subgroup with vitreomacular adhesion, we observed a release of vitreomacular adhesion in 3 out of 18 eyes (16.6%) in the laser group and in 1 out of 13 eyes (7.6%) in the non-laser group (p > 0.05). Conclusion: These findings support a possible beneficial role for prophylactic peripheral laser retinopexy in selected individuals with macular hole.
