Purpose: To assess the anatomic and functional outcomes of eyes undergoing vitrectomy and large retinectomy for the management of retinal detachment (RD) complicated by advanced proliferative vitreoretinopathy (PVR). Methods: A total of 66 eyes of 63 patients with RD complicated by PVR were treated with vitrectomy and 180° or more retinectomy and silicone oil (n=46) or perfluoropropane gas (n=20) were used as intraocular tamponades. Results: Retinal reattachment was achieved in 89.39% (59 eyes) of the cases. The mean follow-up was 33.7 months (range 12-76 months). In gas-filled eyes, the final anatomic success rate was 85% (17 eyes) and in silicone oil-filled eyes was 91.3% (42 eyes) (p=0.46). After the initial retinectomy, the total anatomic success rate was 80.3% (53/66 eyes), 70% in gas-filled eyes (14/20 eyes) and 84.79% in silicone oil-filled eyes (39/46 eyes) (p=0.19). Visual acuity (VA) improved in 37 (56.06%) eyes, remained the same in 19 (28.78%) eyes and became worse in 10 (15.15%) cases. Best corrected VA was ≥20/200 in 22 eyes 33.33%. The final VA was associated with the preoperative VA (r=0.68), the preoperative status of the macula influence significantly the final visual acuity (p<0.0001) and there is statistically significant difference in the final visual acuity between eyes with and without anatomic success (p<0.05). Conclusion: The large circumferential retinectomies can be beneficial in eyes with RD complicated by advanced PVR. No significant difference was found in anatomic success rate, and rate of complications between eyes with silicone oil tamponade and long acting gas undergoing large retinectomy. Regarding the final BCVA, slight difference was found in favor of gas-filled eyes.

Purpose To investigate the morphological and functional correlation between microvascular retinal changes in optical coherence tomography angiography (OCTA) and the microvascular coronary circulation in patients with ST elevation myocardial infarction (STEMI) coronary heart disease (CHD). Methods A total of 330 eyes from 165 participants (88 cases and 77 controls) were enrolled and imaged. Superficial capillary plexus (SCP) and deep capillary plexus (DCP) vascular density was measured in the central (1 mm) and perifoveal (1–3 mm) areas and in the superficial foveal avascular zone (FAZ) and choriocapillaris (3 mm). These parameters were then correlated to the left ventricular ejection fraction (LVEF), and the number of affected coronary arteries. Results Decreased vessel densities in the SCP and DCP and choriocapillaris were positively correlated to the LVEF values ( P = 0.006, P = 0.026, and P = 0.002, respectively). No statistically significant correlation between the SCP and DCP central area or FAZ area was found. Regarding the number of affected vessels, significant negative correlations were revealed for the SCP and DCP central vessel densities ( P < 0.001 and P < 0.001, respectively) and the SCP perifoveal vascular density ( P = 0.009). Conclusions OCTA vascular indices are significantly correlated with morphological and functional parameters in patients with STEMI CHD. SCP vascular density especially seems to be a promising biomarker for the extent of both macrovascular damage (number of affected coronary arteries) and microvascular damage, as mirrored in the decreased LVEF at admission. Translational Relevance OCTA vascular indices offer a valuable insight into the microvascular status of coronary circulation.

We present a case of scleromalacia perforans in an 80-year-old woman. Her vision has deteriorated over the last two years due to progressive astigmatism induced by sclerocorneal thinning.
