RETINA

Purpose:

To identify anomalies of choroidal venous structure in highly myopic (HM) eyes.

Methods:

Widefield indocyanine green angiographic images of 175 HM eyes (refractive error ≤ –6.0D diopters or axial length >26.5 mm) and 100 control eyes taken between January 2014 and December 2018 were reviewed.

Results:

There were no significant differences in age and gender between HM patients and controls. Three types of changes of large choroidal veins were found in 103 HM eyes (58.86%): Asymmetry of vortex veins in 44 eyes (25.14%), isolated long vein across the macula in 58 eyes (33.14%), and intervortex anastomoses in 25 eyes (14.29%). Similar changes in controls were found in 12 eyes (12%), 0 eye (0%), and 2 eyes (2%), respectively, which were significantly lower than those in the HM group (all P

To evaluate the retinal circulation in patients with active acute leukemia, to correlate the perfusion metrics with systemic laboratory values, and to assess the vascular perfusion after leukemia remission.

Background:

Retinal detachment is a severe complication of acute retinal necrosis, threatening vision. The published articles on the effectiveness of laser in preventing retinal detachment in acute retinal necrosis are controversial. Therefore, we aim to evaluate whether prophylactic laser is effective for retinal detachment after acute retinal necrosis.

Methods:

PubMed, Embase, and Cochrane databases were searched, and the retrieved records were screened. Each included study has well-defined laser-treated group and control group without laser treatment or with enough data for manual grouping. The quality of the included studies was assessed using ROBINS-I (“Risk Of Bias In Nonrandomized Studies—of Interventions”). Meta-analysis was conducted to calculate the pooled odds ratios and their 95% confidence interval. Sensitivity analysis was used to test the solidarity, and subgroup analysis was performed to determine the source of heterogeneity.

Results:

Fourteen studies with a total of 532 eyes were eventually included. The quality of the included studies was moderate. The combined results showed that the pooled odds ratio was 0.61 (95% confidence interval [0.41∼0.90], P

Purpose:

To evaluate the outcomes of surgical treatment of refractory vasoproliferative retinal tumors (VPTs) and its complications.

Methods:

Clinical charts of all patients diagnosed with VPTs who underwent surgical treatment from 2005 to 2020 were reviewed. Clinical features, surgical techniques, and outcomes were evaluated.

Results:

From 25 eyes of 23 patients with VPTs, 17 (68%) eyes underwent surgical intervention to treat tumor activity and associated complications including epiretinal membrane (n = 10, 59%), retinal detachment (n = 8, 47%), and vitreous hemorrhage (n = 3, 18%). All eyes underwent pars plana vitrectomy with endolaser/cryotherapy to control tumor activity and to treat associated complications. Three cases required tumor resection. At the end of follow-up (mean 55.4 months, range 2–305 months), no eye presented tumor activity or retinal detachment after one or two surgeries. There was no epiretinal membrane recurrence. The mean baseline best-corrected visual acuity was 1.2 ± 0.7 logMAR, and the mean final best-corrected visual acuity was 0.7 ± 0.6 logMAR (P

Purpose:

To evaluate the caliber of the choroidal veins in central serous chorioretinopathy, a disease proposed to be associated with overloading of choroidal venous outflow.

Methods:

Widefield indocyanine green angiograms of eyes with central serous chorioretinopathy were graded for sausaging defined as three or more contiguous fusiform dilations that vary by at least 50% from the narrowest to largest diameters. A bulbosity was defined as a focal 2X dilation of a blood vessel as compared with the diameter of the surrounding host vessel. The data underwent statistical analysis including the use of generalized estimating equations.

Results:

There were 73 eyes of 41 patients with a mean age of 53.5 years. Sausaging of vessels was seen in a mean and median of three quadrants per eye. Using generalized estimating equations, the only significant risk factor for sausaging was the use of corticosteroids. The two significant predictors of subfoveal choroidal thickness using generalized estimating equations were age (P = 0.021) and proportion of quadrants involved by sausaging (P

A screening protocol for cytomegalovirus retinitis (CMVR) by fundus photography was generated, and the diagnostic accuracy of machine learning technology for CMVR screening in HIV patients was investigated.

Purpose:

To examine 1-year outcomes of metamorphopsia and tangential retinal displacement after epiretinal membrane surgery and identify predictors for metamorphopsia score at 1 year and its improvement from baseline.

Methods:

M-CHARTS were used to measure metamorphopsia. Distances between the intersections of two sets of retinal vessels were measured with infrared or autofluorescence images. Predictors for metamorphopsia scores at 1 year after surgery and their differences from baseline were identified with multivariate regression analysis.

Results:

Ninety-two eyes of 90 consecutive patients were included. The vertical and horizontal distances continued expanding for 1 year (P

Purpose:

To assess changes in choroidal thickness and blood flow in active Vogt–Koyanagi–Harada syndrome and after remission using optical coherence tomography angiography.

Methods:

This was a prospective study of patients with active early uveitis secondary to Vogt–Koyanagi–Harada syndrome. They underwent optical coherence tomography angiography imaging twice: at baseline and after remission on treatment. 3- × 3- and 6- × 6-mm choriocapillaris slabs were used to evaluate parafoveal adjusted flow index as a marker for choroidal blood flow. Mean choroidal thickness of 3 points (subfoveally and 2 points 300 µm parafoveally) was also measured.

Results:

Thirty-nine eyes of 25 patients were initially recruited. After excluding eyes with media opacity, submacular fibrosis, and choroidal neovascularization, 23 eyes of 14 patients were included. The mean follow-up period was 8.7 ± 2.5 months. Mean choroidal thickness in activity and remission was 581.65 ± 108.29 µm and 318.34 ± 72.85 µm respectively (P
