POSTERIOR VITREOUS DETACHMENT STATUS AS A PREDICTIVE FACTOR FOR OUTCOMES OF VITRECTOMY FOR DIABETIC VITREOUS HEMORRHAGE.

PURPOSE: The purpose of this study was to evaluate the prognostic utility of the degree of vitreous attachment for predicting outcomes of vitrectomy for nonclearing vitreous hemorrhage associated with proliferative diabetic retinopathy. METHODS: Medical records of patients who underwent primary vitrectomy for dense nonclearing vitreous hemorrhage secondary to proliferative diabetic retinopathy were examined retrospectively. Eyes were divided into four groups based on the intraoperatively assessed stage of posterior vitreous detachment (PVD), ranging from Stage 0/1 (complete or near-complete vitreoretinal adhesion) to Stage 4 (complete PVD). RESULTS: Overall, 136 eyes (117 patients) were included. In comparison with eyes with a partial or complete PVD (Stages 2-4), eyes with no PVD (Stage 0/1) had a higher incidence of postoperative hypotony (8%, P = 0.03) and traction retinal detachment (27%, P = 0.002), an increased rate of repeat vitrectomy (49%, P = 0.04), and poorer best-corrected visual acuity at 6 months and 1 year postoperatively (P = 0.04 and P = 0.01, respectively). Presence of a complete PVD at baseline was independently associated with improved postoperative vision at 6 months (P = 0.04). CONCLUSION: More extensive vitreoretinal adhesion is associated with higher rates of reoperation and poorer visual outcomes after vitrectomy for dense nonclearing vitreous hemorrhage associated with proliferative diabetic retinopathy. Preoperative determination of PVD status using B-scan ultrasonography may be useful for predicting anatomical and functional outcomes after vitrectomy in these patients.

Rapid reduction of macular edema due to retinal vein occlusion with low-dose normobaric hyperoxia.

PURPOSE: We investigated the effects of a relatively inexpensive, non-invasive, short-term treatment with low-dose normobaric hyperoxia (NBH) on macular edema in patients with retinal vein occlusion (RVO). METHODS: Participants with macular edema associated with RVO were treated with 5 LPM of NBH via facemask (40% fraction of inspired oxygen, FIO2) for 3 h. Patients with non-fovea involving edema who elected to be observed returned for a second treatment 1 month later to test reproducibility. RESULTS: A 3-h session of NBH (n = 45) resulted in decreased maximum macular thickness (MMT) (mean 7.10%, t34=9.63 P<.001) and central macular thickness (CMT) (mean 4.64%, t34=6.90, P<.001) when compared to untreated eyes with RVO measured over the same period of time (n = 12) or their healthy fellow eye (n = 34; MMT:t34=-9.60, P<.001;CMT: t34=-6.72, P<.001). Patients who had a second NBH treatment 1 month later experienced a recurrence of their edema, but demonstrated a similar significant reduction in MMT and CMT after the second NBH treatment. CONCLUSIONS: Three-hour treatment with 40% FIO2 NBH results in a significant reduction in MMT and CMT. This study supports an ischemic mechanism for macular edema associated with retinal vein occlusion. TRANSLATIONAL RELEVANCE: Short-term low-dose normobaric hyperoxia is a simple, inexpensive, and ubiquitous treatment that may provide an alternate or adjunctive approach to treating macular edema in patients who are resistant to or cannot afford anti-VEGF medications.

Anterior versus posterior endoscopic cyclophotocoagulation: comparison of indications, populations, and outcomes.

PURPOSE: To examine how indications, patient characteristics, and outcomes differ between anterior and posterior approaches of endoscopic cyclophotocoagulation (ECP) in the treatment of glaucoma. METHODS: This is a retrospective chart review of 9 anterior and 20 posterior ECP cases (n = 29). RESULTS: Posterior ECP cases were typically associated with a dramatic increase in intraocular pressure (IOP), whereas the anterior ECP was associated with chronically elevated pressures. The initial IOPs in mm Hg of posterior ECP cases (26.8 non-NVG; 35.2 NVG) were much greater than anterior ECP cases (17.8), and a greater overall reduction in IOP was observed in the posterior versus anterior ECP cases (10.3 posterior non-NVG; 21.3 posterior NVG; 3.6 anterior, P < .001). With procedural success defined as 6-month post-operative IOP falling within normal ranges and a decrease in either IOP or number of prescribed glaucoma medications, the success rate of ECP was 92% for posterior NVG, 89% for anterior and 75% for posterior non-NVG cases (P = .34), similar to the previous literature. Of the four unsuccessful cases, two resulted in a normal IOP but lacked a drop in pressure or reduction in medication burden, one resulted in a 6-point drop in IOP but remained at 23 mm Hg, and one resulted in phthisis bulbi (3%) from an initial pressure above 40 mm Hg. CONCLUSION: Endoscopic cyclophotocoagulation is an effective and safe procedure for severe glaucoma cases from both an anterior and posterior approach. Ophthalmologists should consider this procedure as part of their glaucoma treatment arsenal.

SPECTRAL DOMAIN OPTICAL COHERENCE TOMOGRAPHY FINDINGS AND VISUAL OUTCOME AFTER TREATMENT FOR VITREOMACULAR TRACTION.

PURPOSE: To evaluate the capacity of spectral domain optical coherence tomography macular findings to predict best-corrected visual acuity (BCVA) outcomes after treatment for symptomatic vitreomacular traction. METHODS: This consecutive, retrospective study included 24 patients (29 eyes) who experienced vitreomacular traction release with pneumatic vitreolysis (n = 9), intravitreal ocriplasmin (n = 6), or pars plana vitrectomy (n = 14). Preoperative and postoperative spectral domain optical coherence tomography images were used to determine the cone outer segment tips (COST) line, inner segment/outer segment line, and other frequently used features. Correlations between optical coherence tomography findings and BCVA were determined using regression analyses. RESULTS: Postoperative BCVA was correlated with length of the COST line and inner segment/outer segment line defects at 1, 3, 6, and 12 months postoperatively (P < 0.05) by simple linear regression analysis. However, multivariable regression analysis showed that only length of the COST line defect was significantly correlated with BCVA preoperatively and postoperatively (P < 0.05). Postoperative BCVA improvement at 12 months was significantly correlated with preoperative length of the COST line defect (P < 0.01). CONCLUSION: Recovery of the COST line and inner segment/outer segment line defects as observed by spectral domain optical coherence tomography is positively correlated with visual acuity improvement after successful vitreomacular traction treatment. Best-corrected visual acuity improvement may be predicted using the length of the preoperative COST line defect.

EFFICACY AND SAFETY OF TREATMENT OPTIONS FOR VITREOMACULAR TRACTION: A Case Series and Meta-Analysis.

PURPOSE: To evaluate treatment options for vitreomacular traction (VMT). METHODS: A retrospective, consecutive case series and a literature search with Boolean search logic. A random-effects meta-analysis was conducted to combine the rates of VMT resolution per treatment. Patients from studies analyzed were placed into cohorts based on the treatment received. CASE SERIES: Zero of 10 control, 3 of 7 intravitreal ocriplasmin (IVO, P = 0.10), 7 of 8 intravitreal expansile gas (pneumatic vitreolysis, PV, P < 0.01), and 10 of 10 pars plana vitrectomy (P < 0.01)-treated eyes experienced VMT release (VMTr) at Day 28. No patients developed retinal tears or detachment. One PV-treated (12.5%) eye developed a macular hole. Meta-analysis: Twenty-three of 131 prospective or retrospective and consecutive articles were included. Sixty-three eyes were treated with PV, 726 eyes were treated with intravitreal ocriplasmin, and 253 eyes were characterized as the control group (saline injection). The weighted rate of VMT resolution for the control group was 0.09 (95% confidence interval [CI]: 0.06-0.13), PV was 0.84 (95% CI: 0.76-0.92), and intravitreal ocriplasmin was 0.26 (95% CI: 0.23-0.29). CONCLUSION: Our analysis found that PV releases VMT in most patients and suggest that PV may be as effective or superior to nonsurgical options for VMTr at Day 28 with a similar risk profile.

Case-matched comparison of vitrectomy, peripheral retinal endolaser, and endocyclophotocoagulation versus standard care in neovascular glaucoma.

PURPOSE: To evaluate the efficacy of combination pars plana vitrectomy, endoscopic peripheral panretinal photocoagulation, and endocyclophotocoagulation (ECP) as compared with standard care in patients with neovascular glaucoma. METHODS: This age-matched case-controlled retrospective series of 54 eyes compared the clinical outcomes between a consecutive series of combination pars plana vitrectomy/panretinal photocoagulation/ECP (n = 27) versus the current standard of care (n = 27) for patients with neovascular glaucoma. "Standard" treatments for patients with neovascular glaucoma include panretinal photocoagulation, intravitreal bevacizumab, filtration surgery, pars plana vitrectomy, and Ahmed valve placement. RESULTS: After 1 year, mean intraocular pressure reduced from 40.7 ± 12.40 mmHg preoperatively to 12.3 ± 4.84 mmHg (P < 0.001) in the ECP group and from 34.7 ± 12.38 mmHg to 23.2 ± 12.34 mmHg in the control group (P = 0.002). Compared with controls, the mean drop in intraocular pressure in the ECP group was significantly greater at all postoperative visits. Logarithm of the minimal angle of resolution visual acuity outcomes were similar in both groups. There were 2 cases (7.4%) of postoperative phthisis bulbi in each group. CONCLUSION: Endoscopic pars plana vitrectomy, panretinal photocoagulation, and ECP seem to control intraocular pressure to a greater extent than standard glaucoma treatments in patients with neovascular glaucoma. In this aged-matched comparative case series, there was no significant difference between the two treatments' effects on visual acuity.

PERIODONTAL DISEASE AND AGE-RELATED MACULAR DEGENERATION: Results From the National Health and Nutrition Examination Survey III.

PURPOSE: To study the association between periodontal disease (PD) and age-related macular degeneration (AMD). METHODS: For this cross-sectional analysis, 8,208 adults aged 40 years or older with retinal photographs graded for AMD were used from the National Health and Nutrition Examination Survey III. National Health and Nutrition Examination Survey III standardized dental measurements of PD status (defined as loss of >3 mm of attachment between the gum and tooth in at least 10% of sites measured). Participants were stratified into 60 years or younger and older than 60 years of age groups. Association between PD and AMD was assessed while controlling for sex, race, education, poverty income ratio, smoking, hypertension, body mass index, cardiovascular disease, and C-reactive protein. RESULTS: In this population, a total of 52.30% had PD, and the prevalence of AMD was 11.45%. Logistic regression model controlled for confounders and stratified by age 60 years or younger versus older than 60 years showed PD to be independently associated with an increased risk for AMD (odds ratio = 1.96, 95% confidence interval = 1.22-3.14, P = 0.006) for those aged 60 years or younger but not for subjects older than 60 years (odds ratio = 1.32, confidence interval = 0.93-1.90, P = 0.120). CONCLUSION: In this population-based study, PD is independently associated with AMD in those aged 60 years or younger.

Ocular blast injuries in mass-casualty incidents: the marathon bombing in Boston, Massachusetts, and the fertilizer plant explosion in West, Texas.

PURPOSE: To report the ocular injuries sustained by survivors of the April 15, 2013, Boston Marathon bombing and the April 17, 2013, fertilizer plant explosion in West, Texas. DESIGN: Multicenter, cross-sectional, retrospective, comparative case series. PARTICIPANTS: Seventy-two eyes of 36 patients treated at 12 institutions were included in the study. METHODS: Ocular and systemic trauma data were collected from medical records. MAIN OUTCOME MEASURES: Types and severity of ocular and systemic trauma and associations with mechanisms of injury. RESULTS: In the Boston cohort, 164 of 264 casualties were transported to level 1 trauma centers, and 22 (13.4%) required ophthalmology consultations. In the West cohort, 218 of 263 total casualties were transported to participating centers, of which 14 (6.4%) required ophthalmology consultations. Boston had significantly shorter mean distances to treating facilities (1.6 miles vs. 53.6 miles; P = 0.004). Overall, rigid eye shields were more likely not to have been provided than to have been provided on the scene (P<0.001). Isolated upper body and facial wounds were more common in West largely because of shattered windows (75.0% vs. 13.6%; P = 0.001), resulting in more open-globe injuries (42.9% vs. 4.5%; P = 0.008). Patients in Boston sustained more lower extremity injuries because of the ground-level bomb. Overall, 27.8% of consultations were called from emergency rooms, whereas the rest occurred afterward. Challenges in logistics and communications were identified. CONCLUSIONS: Ocular injuries are common and potentially blinding in mass-casualty incidents. Systemic and ocular polytrauma is the rule in terrorism, whereas isolated ocular injuries are more common in other calamities. Key lessons learned included educating the public to stay away from windows during disasters, promoting use of rigid eye shields by first responders, the importance of reliable communications, deepening the ophthalmology call algorithm, the significance of visual incapacitation resulting from loss of spectacles, improving the rate of early detection of ocular injuries in emergency departments, and integrating ophthalmology services into trauma teams as well as maintaining a voice in hospital-wide and community-based disaster planning.

Nocturnal normobaric hyperoxia treatment in a case of chronic diabetic macular edema.

PURPOSE: To study the long-term anatomic and physiologic effects of nocturnal normobaric hyperoxia (NNBH) in a patient with treatment-resistant diabetic macular edema (DME). METHODS: A 64-year-old diabetic man with bilateral DME requiring regular anti-VEGF treatments in both eyes was started on 5 LPM (40% FiO2) NNBH treatment 6-h per night. Visual acuity, OCT measurements of retinal thickness and volume, as well as the number of injections given in each eye were retrospectively examined one year prior and prospectively after initiation of NNBH, as well as before and after a planned 1-month discontinuation of NNBH. RESULTS: The patient received 12 anti-VEGF injections in the year prior to beginning NNBH treatment (4 OD; 8 OS) and did not require any injections after commencing NNBH treatment. Visual acuity improved and stabilized to 20/20 and macular edema rapidly resolved in both eyes following initiation of NNBH. After a planned 1-month NNBH vacation, DME recurred but quickly resolved once NNBH treatment was restarted. CONCLUSION: This model case demonstrates that a 6-h NNBH regimen can be successful in treating DME and improving vision, without the need for intravitreal injections. NNBH is a more acceptable treatment regimen compared to 24-h continuous oxygen delivery and may provide a less invasive alternate method for treating DME in patients with diabetes. Further study is warranted.

Intravitreal Methotrexate for Recalcitrant Epiretinal Membrane Reproliferation.

This article reports a case of a 65-year-old woman with recalcitrant recurrent epiretinal membrane (ERM) treated with revision vitrectomy and membrane peeling followed by 12 weekly intravitreal methotrexate injections. Visual acuity and central macular thickness significantly improved, and no ERM recurrence developed 7 months after surgery. This case represents the first documented use of methotrexate to treat surgically resistant ERM reproliferation and indicates a potential for its use in cases that do not respond to standard treatment. [Ophthalmic Surg Lasers Imaging Retina. 2022;53:49-51.].

Endoscope-Assisted Sutureless Intrascleral Haptic Fixation of a Posterior Chamber Intraocular Lens.

Purpose: In eyes with compromised capsule support, sutureless scleral fixation is a popular method of placing a posterior chamber intraocular lens (PCIOL). We describe an endoscope-assisted sutureless technique for intrascleral fixation of a 3-piece PCIOL. Methods: Eyes of patients who had endoscope-assisted scleral-fixated intraocular lens (SFIOL) implantation were examined retrospectively. The technique comprised direct capture of the IOL haptic with a forceps through a pars plana sclerotomy with subsequent haptic fixation into scleral tunnels created with a 26-gauge needle. The endoscope was used to visualize haptic positioning under the iris and ensure proper centration of the IOL. Results: Thirteen eyes of 13 patients were examined. The mean age of the patients was 68.2 years (range, 38-87 years), and the mean follow-up was 13.6 months (range, 5-23 months). The indications for surgery were a subluxated IOL (6 eyes), postoperative aphakia (5 eyes), and a subluxated cataract (2 eyes). The mean best-corrected visual acuity ± SD improved significantly from 1.2 ± 0.6 logMAR preoperatively to 0.6 ± 0.7 logMAR at last the follow-up (paired Welch t test; t10 = 2.69; P = .023). IOL stability and centration were maintained in all patients. Conclusions: Endoscopic visualization during sutureless SFIOL implantation helped improve haptic localization, minimize intraoperative complications, and achieve excellent IOL centration.

COMBINED PNEUMATIC AND ENZYMATIC VITREOLYSIS FOR SEVERE CASES OF VITREOMACULAR TRACTION.

PURPOSE: To evaluate the efficacy of combined pneumatic and enzymatic vitreolysis for treatment of severe cases of vitreomacular traction (VMT). METHODS: We analyzed a retrospective, consecutive series of five patients diagnosed with severe VMT refractory to pneumatic vitreolysis who then received an additional ocriplasmin injection while their gas bubble from pneumatic vitreolysis was still present between February 2015 and February 2019. Vitreomacular traction release was confirmed using spectral-domain optical coherence tomography. RESULTS: Four of the five patients treated with combined pneumatic and enzymatic vitreolysis achieved VMT release by Day 28, and all cases eventually achieved complete VMT release. In addition to having VMT refractory to pneumatic vitreolysis, patient characteristics included broad adhesion diameter (>1,500 µ m, n = 1), presence of epiretinal membrane (n = 2), age >65 years (n = 4), and pseudophakia (n = 1). The visual acuity improved by three or more lines at 6 months in both of the patients with initial vision worse than 20/50 on an Early Treatment Diabetic Retinopathy Study chart but not in those whose vision was already fairly good (i.e., visual acuity >20/60). None of the patients experienced the following complications after receiving this combined treatment: retinal tears or detachments, vitreous floaters, and ellipsoid zone changes. CONCLUSION: Sequential, combined pneumatic and enzymatic vitreolysis resulted in VMT release in all 5 cases (4 cases by 28 days) and may be a potentially useful alternative to surgical intervention for refractory VMT cases.

Morphologic differences in epiretinal membranes on ocular coherence tomography as a predictive factor for surgical outcome.

PURPOSE: To evaluate whether morphologic differences in idiopathic epiretinal membranes seen on optical coherence tomography may help predict surgical outcomes. METHODS: Seventy-five eyes of 74 patients who underwent primary pars plana vitrectomy with membrane peeling were retrospectively reviewed. Outcome measures included visual acuity, macular contour on optical coherence tomography, central macular thickness, and reoperation rate. RESULTS: According to the preoperative macular contour, 75 eyes were categorized into 4 types: 42 eyes were included in the diffuse (DIF) type, 12 in the cystoid macular edema (CME) type, 14 in the pseudolamellar hole (PLH) type, and 7 in the vitreomacular traction (VMT) type. Surgical procedure significantly improved vision in all types except for the PLH type (DIF, P < 0.0001; CME, P = 0.0378; PLH, P = 0.838; and VMT, P = 0.0273). There was a significant relationship between pre- and postoperative macular contour. All preoperative VMT showed normal contour on postoperative optical coherence tomography but had the highest reoperation rate. CONCLUSION: Surgical intervention for the PLH-type epiretinal membrane was not associated with the visual improvement seen in other epiretinal membrane types, and the VMT type had the highest reoperation rate. Future studies should evaluate the potential benefit of internal limiting membrane peeling with or without short-term gas tamponade in these cases.

A retrospective analysis of triple combination therapy with intravitreal bevacizumab, posterior sub-tenon's triamcinolone acetonide, and low-fluence verteporfin photodynamic therapy in patients with neovascular age-related macular degeneration.

PURPOSE: To assess the efficacy of triple combination therapy (TCT) including bevacizumab (BEV), low-fluence photodynamic therapy, and posterior sub-Tenon's triamcinolone acetonide in patients with wet age-related macular degeneration. METHODS: This institutional review board-approved retrospective consecutive case series included 31 eyes treated for wet age-related macular degeneration with TCT at the Beth Israel Deaconess Medical Center between June 2004 and November 2008. Outcome measures included visual acuity, retinal thickness as measured by optical coherence tomography, time to retreatment, and complications. RESULTS: Triple combination therapy eyes showed significant 3-month and 6-month improvement in visual acuity of 0.140 ± 0.273 logarithm of the minimum angle of resolution and 0.182 ± 0.383 logarithm of the minimum angle of resolution after treatment, respectively (P = 0.0219 and 0.0470, respectively). Central retinal thickness significantly improved at 3 months (-123.8 ± 102.7 µm), 6 months (-87.7 ± 99.8 µm), and 12 months (-101.6 ± 103.3 µm) on optical coherence tomography. Half of eyes that underwent TCT required retreatment by the conclusion of their follow-up, and eyes that underwent TCT had a 1-year Kaplan-Meier survival rate of 62.1 ± 10.8%. CONCLUSION: Triple combination therapy (TCT) appears to effectively improve visual acuity and decrease retinal thickness often without need for subsequent retreatment within the first year of follow-up. Further investigation of TCT in prospective trials is warranted.

Relative Retinal Blood Flow: A Novel and Informative Measure of Unilateral Retinal Vein Occlusion Severity.

Purpose: This study quantifies retinal vascular blood flow affected by unilateral central or branch retinal vein occlusion (CRVO or BRVO). We created a new, unitless metric for the severity of these diseases-relative blood flow (RBF)-and contextualized it with subject demographics, ocular presentation, and systemic conditions. Finally, we explored its efficacy as a predictor of future outcomes. Methods: Data were collected from 20 control subjects and 32 clinically diagnosed CRVO (n = 15) or BRVO (n = 17) patients. We used laser speckle flowgraphy to quantify blood flow as mean blur rate and present RBF as the ratio between the blood flow in a subject's diseased and undiseased eyes. Because of our demonstration that blood flow has high intrapatient (between eyes and over time) but low interpatient correlation in eyes of healthy subjects, any differences between eyes can be attributed to the disease. These data were correlated with subject demographics and disease characteristics. Results: In CRVO and BRVO eyes, average blood flow decreased by 26% and 7%, respectively. In CRVO, occlusion duration, central macular thickness, intraocular pressure, diabetes, previous laser and injection treatments, and injection within three months after measurement were significantly associated with RBF. In BRVO, no significant associations with RBF were found. Conclusions: Blood flow in CRVO and BRVO was reduced compared to the unaffected fellow eye in most patients. RBF was useful in determining the severity of RVOs and predicting future treatment needs. Translational Relevance: RBF is a promising new and informative metric for quantifying the severity of unilateral RVOs.

Recalcitrant Macular Hole Closure by Autologous Retinal Transplant Using the Peripheral Retina.

PURPOSE: The peripheral adult human retina has been found to contain neuroepithelial stem cells. In this study, we examined the efficacy of an auto-transplant of peripheral retina into refractory macular holes (MH) from both anatomic and physiologic perspectives. METHODS: The population consisted of four female patients aged 72, 82, 65 and 84 years (cases 1-4, respectively) with persistent refractory MH status; internal limiting membrane (ILM) peeling (case 1), ILM transplant (case 2), and inverted ILM (cases 3 and 4 with myopic MH). In all our cases, retinal grafts were harvested beyond the equator from the far retinal periphery using curved horizontal scissors and gently moved toward the MH using a forceps. A 25-G manipulator with a silicone ball tip was used to tuck the trimmed graft into the MH, followed by fluid-air exchange and infusion of silicone oil, which was removed three months later. RESULTS: Partial restoration and integration of the outer retinal layer were confirmed on an OCT-B scan imaging. The visual acuity (VA) was improved in all cases: 1.2 to 1.0 logMAR (case 1), 2.0 to 1.3 logMAR (case 2), 2.3 to 1.4 logMAR (case 3) and 2.0 to 1.0 logMAR (case 4). Microperimetry showed improved retinal sensitivity in every case. No intra- or post-operative complications were observed. CONCLUSION: Under pathological conditions, the Müller glia reportedly serves as a source of neuronal progenitor cells in regenerating retina, continuing to divide and migrate to the outer nuclear layer thus replacing lost photo-receptors. Although the histological findings remain unknown, the positive anatomic and physiologic outcomes of the auto-transplanted retinal flap in our series suggest that this technique may offer an effective option for treating recalcitrant MH. Further studies are warranted.

Mineralocorticoid Receptor Antagonists in Central Serous Chorioretinopathy: A Meta-Analysis of Randomized Controlled Trials.

TOPIC: A meta-analysis comparing mineralocorticoid receptor (MR) antagonists (eplerenone or spironolactone) versus observation or placebo in the treatment of central serous chorioretinopathy (CSCR) based on best-corrected visual acuity (BCVA) and subretinal fluid (SRF) level data from randomized controlled trials (RCTs). CLINICAL RELEVANCE: Central serous chorioretinopathy patients may demonstrate decreased visual acuity, reduced contrast sensitivity, scotomas, and metamorphopsia. Although multiple treatment options for CSCR have been proposed, compelling evidence for any particular method is still lacking. METHODS: Three databases (PubMed, EMBASE, and BIOSIS) were searched for potentially relevant records as of March 2018. Of 114 unique studies identified, 5 RCTs comparing BCVA with either eplerenone or spironolactone versus observation or placebo were included. The quality of articles was assessed according to the Cochrane Risk of Bias Tool, with any discrepancies resolved by author consensus. RESULTS: A total of 145 eyes of patients with CSCR were included in the meta-analysis. Compared with placebo or observation, MR antagonist treatment showed a significant positive effect on BCVA after both 1 month (weighted mean difference [WMD], -0.05 logarithm of the minimum angle of resolution [logMAR]; 95% confidence interval [CI], -0.07 to -0.02 logMAR; Z = 3.94; P < 0.0001) and 2 months (WMD, -0.10 logMAR; 95% CI, -0.14 to -0.06 logMAR; Z = 4.69; P < 0.00001). Mineralocorticoid receptor antagonist treatment also significantly reduced SRF height in CSCR at 1 month (WMD, -81.15 µm; 95% CI, -148.25 to -14.05 µm; Z = 2.37; P = 0.02). However, this effect was no longer significant at 2 months (WMD, -58.63 µm; 95% CI, -155.40 to 38.13 µm; Z = 1.19; P = 0.23). None of the patients in the 5 trials withdrew because of adverse effects, and blood electrolyte levels, including potassium, remained normal in all cases. CONCLUSIONS: Our findings suggest a modest benefit with MR antagonist therapy for CSCR patients in improving BCVA. We anticipate that MR antagonists will be well tolerated by most CSCR patients and that barriers to starting a trial of these medications in nonresolving CSCR should be low.

BILATERAL CENTRAL RETINAL VEIN OCCLUSIONS IN A YOUNG PATIENT WITH A HISTORY OF EOSINOPHILIC PNEUMONIA AND THALAMIC STROKE.

PURPOSE: To describe a case of a central retinal vein occlusion in a young patient with a history of eosinophilic pneumonia. METHODS: A retrospective case report of a 45-year-old woman with acute painless vision loss for 9 days after multiple episodes of eosinophilic pneumonia and thalamic stroke. Fluorescein angiography, spectral domain optical coherence tomography, and clinical examination were performed. She was then treated with intravitreal bevacizumab and pan-retinal photocoagulations. RESULTS: Retinal examination revealed tortuosity and dilatation of all branches of the central retinal vein and flame-shaped hemorrhages in all four quadrants of the right eye associated with cystoid macular edema, optic disc edema, and cotton wool spots. The left eye had mild venous dilatation and tortuosity with a few dot retinal hemorrhages in the far temporal periphery. The cystoid macular edema resolved after one intravitreal injection of bevacizumab and remained resolved at the most recent follow-up. Fluorescein angiography at the most recent follow-up revealed vasculitis in the far periphery of the nontreated eye. CONCLUSION: Central retinal vein occlusion in young patients is a rare condition often presenting as a manifestation of an underlying inflammatory or hematological disorder. Combined anti-vascular endothelial growth factor treatment and pan-retinal photocoagulation may have resolved the associated cystoid macular edema in this case, although continued observation is necessary.
