EFFECT OF PHYSICIAN FACE MASK USE ON POSTINJECTION ENDOPHTHALMITIS

imagePurpose:

To examine the impact of physician face mask use on the rates and outcomes of postinjection endophthalmitis.

Methods:

A multicenter retrospective, comparative cohort study comparing endophthalmitis rate and visual acuity of eyes that developed endophthalmitis after antivascular endothelial growth factor injections at Mayo Clinic Rochester (MCR) and at Mayo Clinic Health System sites depending on physician masking.

Results:

A total of 164,824 injections were performed at MCR and Mayo Clinic Health System sites. Of these, 66,098 injections were in the no mask group and 98,726 injections were in the mask group. Overall, there were no differences in the rates of infectious endophthalmitis in the no mask versus mask cohorts (overall: no mask: 20 cases [0.0303%] vs. mask: 41 cases (0.0415%); P = 0.24; infectious: no mask: 12 cases [0.018%] versus mask: 13 cases [0.0132%]; P = 0.42). At MCR alone, there was a significant reduction in infectious endophthalmitis between the no mask versus mask groups (no mask: 9 cases [0.0297%] versus mask: 2 cases [0.003%]; P

OPTICAL COHERENCE TOMOGRAPHY FINDINGS IN CHOROIDAL MELANOMA-ASSOCIATED SUBRETINAL FLUID

imagePurpose:

To report optical coherence tomography findings of choroidal melanoma with subretinal fluid (SRF).

Methods:

Single-center, retrospective review of spectral-domain optical coherence tomography in treatment-naive choroidal melanoma with associated SRF presenting between July 2009 and August 2021.

Results:

Of 236 included patients, choroidal melanoma was small (n = 98, 41.5%), medium (n = 99, 41.9%), or large (n = 39, 16.5%). The most common optical coherence tomography feature was ellipsoid zone loss/disruption (n = 174, 73.7%), with unique features of bacillary layer detachment (n = 67, 28.4%), and heterogenous (n = 72, 30.5%) or homogenous (n = 48, 20.3%) subretinal hyperreflective material. Comparison (small vs. medium vs. large) revealed greater SRF extent with increasing tumor size (SRF ≥2 quadrants: 6.1% vs. 27.2% vs. 67.7%, P

CULTURE POSITIVITY RATES OF DEEP VITREOUS BIOPSY UNDER AIR VIS-À-VIS CONVENTIONAL ANTERIOR VITREOUS BIOPSY IN ENDOGENOUS ENDOPHTHALMITIS

imagePurpose:

To describe the comparison of the culture positivity rates of deep vitreous biopsy under air and conventional anterior vitreous biopsy in endogenous endophthalmitis.

Materials:

A retrospective, consecutive, comparative series including cases of endogenous endophthalmitis from January 2014 to January 2021. They were divided into those where conventional anterior vitreous biopsy was taken and those where a deep biopsy was taken under air (DBA group). The culture positivity rate among the two groups was compared, and factors affecting the same were analyzed by a regression analysis.

Results:

There were 140 eyes in the conventional anterior vitreous biopsy group and 44 eyes in the DBA group. Sex, age, duration of symptoms, underlying systemic illness, presenting vision in logMAR, and total number of vitreous interventions were comparable between the two groups. Visual outcome was better in patients undergoing DBA as compared with those who underwent conventional anterior vitreous biopsy , (1.28 ± 1.01 logMAR, 20/380 vs. 1.88 ± 1.33 logMAR, 20/1,500, P = 0.03). No case in the DBA group developed retinal detachment or any complication attributable to the technique. In the conventional anterior vitreous biopsy group, the culture positivity was seen in 43/140 samples (30.71%), and in the DBA group, it was noted in 29/44 samples (65.9%). Taking a DBA was the only factor that was significant both in bivariate (odds ratio 4.36, 95% confidence interval 2.12–8.95, P

THE IMPACT OF THE VITREOMACULAR INTERFACE ON FUNCTIONAL AND ANATOMICAL OUTCOMES IN DIABETIC MACULAR EDEMA TREATED WITH THREE DIFFERENT ANTI-VEGF AGENTS: Post Hoc Analysis of The Protocol T Study

imagePurpose:

To investigate the impact of baseline vitreomacular interface status on treatment outcomes in patients treated with three different anti–vascular endothelial growth factors for diabetic macular edema.

Methods:

Post hoc analysis from patients enrolled in the DRCR.net Protocol T study. Optical coherence tomography images were analyzed at baseline and at the end of follow-up to identify the presence of complete vitreomacular adhesion, partial vitreomacular adhesion, vitreomacular traction syndrome, and complete posterior vitreous detachment.

Results:

Six hundred and twenty-nine eyes were eligible for the study based on the study criteria. Complete adhesion eyes gained on average +3.7 more ETDRS letters compared with the complete posterior vitreous detachment group at the end of the 12 months follow-up (P

MACULAR BUCKLING COMBINED WITH VITRECTOMY AND INVERTED INTERNAL LIMITING MEMBRANE FLAP TECHNIQUE FOR MACULAR HOLES WITH MACULAR RETINOSCHISIS WITHOUT RETINAL DETACHMENT IN HIGH MYOPIA

imagePurpose:

To investigate the outcomes of macular buckling combined with vitrectomy and inverted internal limiting membrane flap technique for highly myopic full-thickness macular hole (FTMH) with macular retinoschisis.

Methods:

Twenty-six eyes of 26 consecutive patients were retrospectively included. Twelve eyes underwent macular buckling alone (buckling group). Fourteen eyes underwent macular buckling and vitrectomy with an inverted internal limiting membrane flap technique (combination group). Patients were followed for at least 9 months. Rates of FTMH closure and macular retinoschisis resolution, best-corrected visual acuity gained at the final visit were evaluated.

Results:

The mean follow-up time was 13.00 ± 3.16 months. FTMH closed in six eyes (50%) of the buckling group and 13 eyes (92.86%) of the combination group (P = 0.026) at the final visit. The macular retinoschisis resolution rate was close between two groups (100% vs. 92.86%; P = 1.000). Both groups achieved significant improvement in best-corrected visual acuity (10.42 ± 17.25 and 16.36 ± 10.39 Early Treatment Diabetic Retinopathy Study letters; P = 0.014 and P
