OUTCOMES OF INFECTIOUS PANUVEITIS ASSOCIATED WITH SIMULTANEOUS MULTI-POSITIVE OCULAR FLUID POLYMERASE CHAIN REACTION.

PURPOSE: To evaluate features of infectious panuveitis associated with multiple pathogens detected by ocular fluid sampling. METHODS: Single-center, retrospective, consecutive case series of patients with aqueous/vitreous polymerase chain reaction testing with >1 positive result in a single sample from 2001 to 2021. RESULTS: Of 1,588 polymerase chain reaction samples, 28 (1.76%) were positive for two pathogens. Most common pathogens were cytomegalovirus (n = 16, 57.1%) and Epstein-Barr virus (n = 13, 46.4%), followed by varicella zoster virus (n = 8, 28.6%), Toxoplasma gondii (n = 6, 21.4%), herpes simplex virus 2 (n = 6, 21.4%), herpes simplex virus 1 (n = 6, 21.4%), and Toxocara (n = 1, 3.6%). Mean initial and final visual acuity (logarithm of the minimum angle of resolution) were 1.3 ± 0.9 (Snellen ∼20/400) and 1.3 ± 1.1 (Snellen ∼20/400), respectively. Cytomegalovirus-positive eyes (n = 16, 61.5%) had a mean final visual acuity of 0.94 ± 1.1 (Snellen ∼20/175), whereas cytomegalovirus-negative eyes (n = 10, 38%) had a final visual acuity of 1.82 ± 1.0 (Snellen ∼20/1,320) ( P < 0.05). Main clinical features included intraocular inflammation (100%), retinal whitening (84.6%), immunosuppression (65.4%), retinal hemorrhage (38.5%), and retinal detachment (34.6%). CONCLUSION: Cytomegalovirus or Epstein-Barr virus were common unique pathogens identified in multi-PCR-positive samples. Most patients with co-infection were immunosuppressed with a high rate of retinal detachment and poor final visual acuity. Cytomegalovirus-positive eyes had better visual outcomes compared with cytomegalovirus-negative eyes.

Identification of macular neovascularization in central serous chorioretinopathy using swept-source OCT angiography.

Purpose: Swept-source optical coherence tomography angiography (SS-OCTA) was used to detect the presence of macular neovascularization (MNV) in eyes with exudative central serous chorioretinopathy (CSCR). Observations: Case 1 is a 73-year-old man using prednisolone drops with 20/40 vision and a retinal pigment epithelial detachment (PED) associated with subretinal fluid (SRF) and no clinical signs of age-related macular degeneration (AMD) in his left eye. Three months after presentation he underwent SS-OCTA imaging that revealed MNV. He received a series of intravitreal anti-vascular endothelial growth factor (VEGF) injections and SS-OCTA imaging showed a decrease in the MNV lesion size with resolution of the SRF. VA improved to 20/25. Case 2 is a 65-year-old man with recent oral steroid use, presenting with 20/20 vision, a PED, SRF, and no evidence of AMD. SS-OCTA imaging at presentation revealed MNV, which worsened on interval SS-OCTA imaging after the patient deferred treatment. Intravitreal anti-VEGF therapy was then performed with resolution of the SRF and VA improved to 20/15. A total of six cases of type 1 MNV were diagnosed with CSCR. Most were men with a history of steroid or testosterone use and were treated with good response. Conclusions and importance: SS-OCTA imaging provides a convenient non-invasive strategy for identifying CSCR eyes with MNV without the need for dye-based angiography.

Rates of Fellow Eye Macular Hole Development During Long Term Follow-Up.

Purpose: Identify the long-term rate of fellow eye full-thickness macular hole (FTMH) development. Patients and Methods: In this single site, single provider retrospective consecutive case series, idiopathic FTMH patients who underwent surgery from 2003 to 2014 who also had at least 5 years of follow-up information within our electronic medical record (EMR) which was started in 2014 were identified. Cases with secondary causes (ie, trauma), high myopia, bilateral FTMH on presentation, previous retinal surgery, retinal breaks, or intraocular inflammation were excluded. Demographics, medical and ocular history, refractive error, phakic status, best corrected visual acuity, follow-up duration, surgical technique, single operation anatomic success, and reoperations were recorded. Results: The rate of fellow eye FTMH was 2.6% (2/77) at 1 year, 5.2% (4/77) at 3 years, 9.1% (6/66) at 6 years, and 9.1% (7/77) as of final follow up. There were 2 cases by year 1, 2 additional cases by year 3, 2 additional cases by year 6, and 1 additional case reported thereafter. The average follow up was 11.1 ± 4.5 years. There was no significant difference in visual outcomes between primary eyes and fellow eyes. There was no significant difference in gender, age, ocular comorbidities, refractive error, phakic status, and visual acuity between the unilateral and bilateral groups. Conclusion: The rate of FTMH in the fellow eye was low but significant, increased during long-term follow up, and may stabilize after 6 years.

Return to the Operating Room After Repair of Rhegmatogenous Retinal Detachment.

Purpose: To report the rate of all-cause returns to the operating room (OR) after surgery for rhegmatogenous retinal detachment (RRD). Patients and Methods: This was a retrospective consecutive case series; 1278 eyes underwent RRD repair from 1/1/2014 to 12/31/2016 at a tertiary care center. A total of 507 eyes returned to the OR. Surgical indication, procedure, number of reoperations, and final vision were recorded. Results: At least one secondary procedure was performed in 24.9% at 6 months, 34.7% at 1 year, and 39.7% as of last follow-up. The most common indications for reoperation were cataract (43.9%) and recurrent RRD (12.8%). Cornea, glaucoma, and oculoplastic issues were rare (each <1.1%). There was no association between final visual outcome and number of reoperations (p > 0.05). SB/PPV had the highest rate of return to OR (p < 0.001) but lowest rate of recurrent RRD (p = 0.007). Conclusion: To our knowledge, there are no other large studies that examine all-cause returns to the OR after primary RRD repair. This study provides important risk-benefit and prognostic information to patients undergoing RRD repair.

CRVO associated with COVID-19 and MTHFR mutation in a 15-year-old male.

Purpose: To report a case of a central retinal vein occlusion (CRVO) associated with COVID-19 in a patient predisposed to clotting due to a genetic mutation in methylenetetrahydrofolate reductase (MTHFR). Observations: A 15-year-old male presented with 1 day of painless blurry vision in the left eye. Exam disclosed trace anterior chamber cell, anterior vitreous cell, optic nerve head edema, temporally displaced macular star, dilated tortuous veins, and diffuse intraretinal hemorrhages. Exam and FA was consistent with CRVO, however the macular star and OCT were suggestive of a neuroretinitis.The patient then presented to a children's hospital for further evaluation. A routine screen for COVID-19 via nasopharyngeal swab was positive with a high viral load. He also had a known history of an MTHFR mutation. Extensive laboratory and neuroradiologic evaluation excluded other infectious, inflammatory, and coagulopathic etiologies. Conclusions and Importance: This is a case of CRVO associated with COVID-19 infection and an underlying systemic hypercoagulable mutation, with an initial presentation that mimicked neuroretinitis. This case provides valuable diagnostic learning points and expands our knowledge of possible ocular complications of COVID-19.

Endophthalmitis Caused by Streptococcus:Clinical Outcomes and Antimicrobial Susceptibilities 2014-2019.

BACKGROUND AND OBJECTIVE: To report the clinical settings, antibiotic susceptibilities, and outcomes of streptococcal endophthalmitis. PATIENTS AND METHODS: Retrospective case series evaluating culture-positive streptococcal endophthalmitis from January 1, 2014, to December 31, 2019. RESULTS: Thirty-eight eyes met study criteria. The most common clinical setting was post-glaucoma surgery (33.3%, 12/36). The most frequent isolate was Streptococcus viridans (63.2%, 24/38). Isolates were susceptible to vancomycin (100%, 36/36), ceftriaxone (100%, 28/28), and levofloxacin (100%, 36/36). Final best-corrected visual acuity was 20/150 or better in 24.1% (7/29) but 20/200 or worse in 75.9% (22/29). Enucleation was performed in 11.1% (4/36). A subset (n = 11) of cases were evaluated for streptococcal-specific virulence factors: pneumolysin was present in 18.2% (2/11), autolysin in 45.5% (5/11), and hyaluronidase in 54.5% (6/11). Clinical setting, antibacterial susceptibilities, timing of pars plana vitrectomy, and virulence factor presence were not associated with better visual outcome or enucleation rate (P > .05). CONCLUSION: Visual prognosis for streptococcal endophthalmitis is poor despite early and appropriate antibiotic treatment. [Ophthalmic Surg Lasers Imaging Retina. 2021;52:182-189.].

Widefield Fluorescein Angiography in the Fellow Eyes of Patients with Presumed Unilateral Persistent Fetal Vasculature.

PURPOSE: To examine the retinal vascular findings on widefield fluorescein angiography (FA) in the fellow eyes of patients with unilateral persistent fetal vasculature (PFV). DESIGN: Retrospective case series. PARTICIPANTS: Consecutive patients with unilateral PFV evaluated by a single physician at an academic medical center from February 1, 2011, to November 30, 2018. METHODS: Clinical and demographic information, including age, gender, race, ethnicity, affected eye, subtype, stalk origin, complications on presentation, length of follow-up, and examination findings, was reviewed using the electronic medical record. Fluorescein angiograms of the affected and fellow eyes were reviewed by 2 authors for characteristic retinal vascular abnormalities. Agreement between the authors' scores was analyzed using Cohen's Kappa. MAIN OUTCOME MEASURES: Fluorescein angiography abnormalities, including peripheral vessel avascularity, aberrant circumferential vessels, terminal supernumerary branching, regional capillary dropout, terminal bulbing, abnormal choroidal flush, abnormal vessel straightening, and peripheral vessel leakage or dilation. RESULTS: Inclusion criteria were met by 41 patients. The average age at initial visit was 10.0 months. The average length of follow-up was 36.4 months. Abnormalities on FA were seen in 31 (75.6%) fellow eyes: peripheral vessel avascularity in 27.5 (67.1%), aberrant circumferential vessels in 20 (48.8%), terminal supernumerary branching in 17 (41.5%), regional capillary dropout in 9 (22.0%), terminal bulbing in 6 (14.6%), abnormal choroidal flush in 3.5 (8.5%), and abnormal vessel straightening and peripheral vessel leakage in 2.5 (6.1%). Statistical analysis disclosed an overall observed agreement of 93.4% among the raters (κ = 0.84, P < 0.0001). CONCLUSIONS: Retinal vascular abnormalities seen in patients with unilateral PFV were present in the majority of fellow eyes. This suggests that unilateral PFV may in fact be a bilateral, asymmetric process, but the clinical significance of these subtle findings is not known.

Analysis of Socioeconomic Factors Affecting Follow-Up in a Glaucoma Screening Program.

PURPOSE: To determine what socioeconomic factors affect follow-up in a glaucoma screening program. PATIENTS AND METHODS: This was a retrospective cohort study of six health fairs in South Florida from October 2012 to March 2013 among socially and economically disadvantaged populations. Visual acuity (VA), intraocular pressure (IOP), cup-to-disc ratio (CDR), and visual field testing were obtained to identify glaucoma suspects. Glaucoma suspects were defined as having intraocular pressure ≥24 mm Hg, cup-to-disc ratio of ≥0.6 in either eye, or glaucomatous defects on visual field testing. In July 2015, telephone surveys were administered to assess follow up and socioeconomic factors. RESULTS: Seventy-two out of 144 (50%) glaucoma suspects responded to the survey and were included in the analysis. Of the 72 respondents, average age was 52.8 years old and 65% were female. The most common race was African American (69%) and ethnicity was Haitian (51%). Glaucoma suspects who followed up were significantly more likely to have health insurance compared to those who did not follow up (74% vs 43%, p = 0.014). No significant difference in follow-up based on age (p = 0.125), education (p = 0.151), gender (p = 0.48), or ethnicity (p = 0.707) was identified. Of the 30 respondents, who did not follow up, the most common reasons were "no insurance" (57%, 17/30) and "not worried" (33%, 10/30). CONCLUSION: Insurance was the main socioeconomic factor in determining whether glaucoma suspects followed up after community health screenings. Streamlining social services could increase clinical access of glaucoma suspects.

Clinical Outcomes in Sequential, Bilateral Rhegmatogenous Retinal Detachment: A Multicenter, Paired-Eye Analysis.

PURPOSE: To assess the clinical outcomes in patients with sequential, bilateral rhegmatogenous retinal detachment (RRD) by using a paired-eye comparison. DESIGN: Multicenter, retrospective cohort study. PARTICIPANTS: Patients with sequential, bilateral RRD treated with pars plana vitrectomy (PPV), scleral buckle (SB), or PPV plus SB over an 11-year period (October 2008-April 2019) from 4 vitreoretinal practices were included. METHODS: Data were collected on patient demographics, anatomic characteristics of the RRD, surgical procedures, and best-corrected visual acuity (VA). These variables, along with single-operation anatomic success (SOAS) and type and number of surgical procedures, were assessed with a paired-eye comparison. MAIN OUTCOME MEASURES: Single-operation anatomic success between the initial-eye and subsequent-eye RRD. RESULTS: Five hundred four eyes of 252 patients were included. The mean interval between RRD in either eye was 13.6 ± 13.4 months. Single-operation anatomic success in the initial eye was 82.5% with a mean of 1.2 surgeries (range, 1-4 surgeries). Single-operation anatomic success in the subsequent eye was 83.7% (P = 0.80) with a mean of 1.2 surgeries (range, 1-4 surgeries; P = 0.68). Visual acuity was better in the subsequent eye at presentation (mean, 20/62 vs. 20/149; P < 0.001) and postoperative month 6 (mean, 20/41 vs. 20/49; P = 0.03), but final VA was similar (20/36 vs. 20/37; P = 0.68). Macular detachment was less prevalent (34.1% vs. 56.0%; P < 0.001) with fewer quadrants detached (mean, 1.9 quadrants vs. 2.0 quadrants; P = 0.010) in the subsequent eye. Mean duration of symptoms was shorter in the subsequent eye (mean, 5.9 days vs. 7.5 days; P = 0.008). In patients who underwent a different surgical technique in each eye, PPV plus SB yielded a higher SOAS of 89.7% compared with 69.0% for PPV alone in 116 eyes (P = 0.010). CONCLUSIONS: In this study of sequential, bilateral RRD, the SOAS was similar for each eye. The second eye was more likely to be treated earlier and to have less macular involvement, but the final VA outcomes were similar. Pars plana vitrectomy plus SB yielded a significantly higher SOAS than PPV or SB alone.

Novel Frizzled-4 Mutation Is Associated With Familial Exudative Vitreoretinopathy Mimicking Persistent Fetal Vasculature.

This is a report of a 13-month-old boy who presented with a large unilateral fibrovascular stalk and bilateral peripheral retinal avascularity. Although consistent with both persistent fetal vasculature and familial exudative vitreoretinopathy, genetic testing disclosed a novel pathogenic mutation in the frizzled class receptor 4 gene (FZD4, c.427_428delCT).

MANAGEMENT OF LARGE OR RECURRENT MACULAR HOLES.

PURPOSE OF REVIEW: To review and critically appraise the recent literature about new surgical techniques for the management of large or recurrent macular holes. RECENT FINDINGS: A variety of surgical approaches have recently been developed ranging from autologous retinal grafts to amniotic membrane transplant with varying levels of anatomical and visual success. SUMMARY: More data is needed to determine if one technique is superior to others. However, with a variety of grafts, adhesives, and tamponades at their disposal, vitreoretinal surgeons have an extensive array of options to approach complex macular holes.

Visual and anatomic outcomes of cataract surgery with intraoperative or postoperative complications in a teaching institution.

OBJECTIVE: To review visual and anatomic outcomes after cataract surgery with complications in a teaching institution. METHODS: Consecutive case series. A chart review was conducted of patients who underwent phacoemulsification with intraoperative or postoperative complications, performed by ophthalmology residents under direct supervision of experienced ophthalmology attending physicians. Best corrected visual acuity (BCVA), OCT parameters, and postoperative treatments were reviewed at 1, 3, 6, and 12 months postoperatively. RESULTS: One hundred thirty-three eyes were analyzed. Mean BCVA was 50 ± 23 approximate Early Treatment Diabetic Retinopathy Study letters at the preoperative visit and improved by a mean of 8 letters (n = 128; p = 0.001), 16 letters (n = 117; p < 0.001), 14 letters (n = 79; p < 0.001), and 4 letters (n = 34; p = 0.37) at 1, 3, 6, and 12 months. The mean OCT central subfoveal thickness increased by less than 50 µm at all time points and this change was not statistically significant at 12 months. BCVA increased by 3 lines in 41%, 56%, 57%, and 44% of eyes at 1, 3, 6, and 12 months. Median BCVA was 20/40 or better at each follow-up period. Fifty-three (40%) eyes required a secondary surgical procedure due to intraoperative or postoperative complication. A significant proportion of eyes received anti-inflammatory drops through 1 year. CONCLUSIONS: After cataract surgery with intraoperative or postoperative complications, a majority of eyes experienced substantial visual gains and only mild retinal thickening while being managed with long-term anti-inflammatory drops and additional surgical procedures.

Surgical Simulation Training Reduces Intraoperative Cataract Surgery Complications Among Residents.

INTRODUCTION: This retrospective consecutive case series examined whether training on a surgical simulator reduces intraoperative complication rates among novice ophthalmology residents learning cataract surgery. METHODS: Beginning July 2014, training on the Eyesi simulator became mandatory for novice postgraduate year 3 ophthalmology residents before live cataract surgery at our institution. Complication rates of the 11 simulator-trained residents (study group) were compared with their immediate 11 simulator-naive predecessors (comparison group). Only straightforward cataract cases (according to standardized preoperative criteria) where postgraduate year 3 residents served as the primary surgeon were included. Complication data were obtained from Morbidity and Mortality records and compared using Fisher exact test. A survey was administered to the residents to gauge the perceived utility of simulation training. RESULTS: The simulator-trained group (n = 501 cataract cases) and the simulator-naive comparison group (n = 454 cases) were analyzed. The complication rate in the simulator group was 2.4% compared with 5.1% in the comparison group (P = 0.037, Fisher exact test). Both the mean posterior capsule tear rate and vitreous prolapse rate in the simulator group were 2.2% compared with 4.8% in the comparison group (P = 0.032, Fisher exact test). The survey had a response rate of 100% (11/11), and 91% (10/11) of respondents felt that the training was "extremely worthwhile" and should be mandatory. CONCLUSIONS: The addition of surgical simulation training was associated with a significantly reduced rate of complications, including posterior capsule tears and vitreous prolapse, among novice postgraduate year 3 residents. There is a perceived utility among residents to incorporate virtual simulation into surgical training.
