RESUMO

PURPOSE: To report on macular hole repair in macular telangiectasia type 2 (MacTel2). DESIGN: Global, multicenter, retrospective case series. PARTICIPANTS: Patients undergoing surgery for MacTel2-associated full-thickness macular hole (MTMH). METHODS: Standardized data collection sheet distributed to all surgeons. MAIN OUTCOME MEASURES: Anatomic closure and visual outcomes of MTMH. RESULTS: Sixty-three surgeries in 47 patients with MTMH were included from 30 surgeons. Mean age was 68.1 years, with 62% female, 72% White, 21% East or South Asian, 2% African American, and 2% Hispanic or Latino. Procedures included 34 internal limiting membrane (ILM) peeling alone, 22 ILM flaps, 5 autologous retinal transplantations (ARTs), 1 retinotomy, and 1 subretinal bleb. For ILM peeling, preoperative visual acuity (VA) was 0.667 ± 0.423 logarithm of the minimum angle of resolution (logMAR). Minimum hole diameter (MHD) was 305.5 ± 159.4 µm (range, 34-573 µm). Sixteen of 34 ILM peels (47%) resulted in MTMH closure. At postoperative month 6, VA was stable at 0.602 ± 0.516 logMAR (P = 0.65). VA improved by at least 2 lines in 43% and at least 4 lines in 24%. For ILM flaps, preoperative VA was 0.878 ± 0.552 logMAR. MHD was 440.8 ± 175.5 µm (range, 97-697 µm), which was significantly larger than for ILM peels (P < 0.01). Twenty of 22 ILM flaps (90%) resulted in MTMH closure, which was significantly higher than for ILM peels (P < 0.01). At postoperative month 6, VA improved to 0.555 ± 0.405 logMAR (P < 0.05). VA improved by at least 2 lines in 56% and at least 4 lines in 28%. For ARTs, preoperative VA was 1.460 ± 0.391 logMAR. MHD was 390.2 ± 203.7 µm (range, 132-687 µm). All 5 ARTs (100%) resulted in MTMH closure. At postoperative month 6, VA was stable at 1.000 ± 0.246 logMAR (P = 0.08). Visual acuity improved at least 2 lines in 25%. CONCLUSIONS: Surgical closure of macular holes improved VA in 57% of MTMHs. Internal limiting membrane flaps achieved better anatomic and functional outcomes than ILM peeling alone. Autologous retinal transplantation may be an option for refractory MTMHs.

RESUMO

PURPOSE: Although pivotal trials have demonstrated efficacy of anti-vascular endothelial growth factor therapy in neovascular age-related macular degeneration, there is a paucity of clinical data about the long-term (>5 years) treatment. METHODS: Retrospective analysis of all patients with neovascular age-related macular degeneration who were actively treated, had received >40 anti-vascular endothelial growth factor injections, and were followed for ≥5 years. Snellen-corrected visual acuity, initial drug choice, and times elapsed between treatments were collected. Rates of endophthalmitis and outcomes of submacular hemorrhage were also evaluated. RESULTS: A total of 88 patients (162 eyes) met the inclusion criteria: the average patient age was 86.3 years with an average follow-up period of 7.6 years. The average total number of injections per eye was 69 (18.0 SD); a total of 11,208 injections were given throughout the study period, and 6 cases (0.05%) of endophthalmitis were observed. Overall, there was a clinical and statistical difference in average Snellen-corrected visual acuity at Injections #2,#3, #4, #5, #6, #10, and #20, as compared with baseline ( P = 0.03, P < 0.01, P = 0.02, P < 0.01, P = 0.01, P = 0.01, P < 0.01, respectively). Patients in the Snellen-corrected visual acuity subgroup 20/20 to 20/40 maintained vision until injection #30. Seven eyes experienced a visually significant submacular hemorrhage. CONCLUSION: This neovascular age-related macular degeneration cohort received on average eight anti-vascular endothelial growth factor injections per year for approximately 8 years; eyes with good (≥20/40) initial baseline vision maintained their visual acuity, whereas those with worse Snellen-corrected visual acuity (≤20/50) had a robust initial improvement that diminished with time. Most patients were maintained on the same initial drug of choice and the rate of endophthalmitis was low.

RESUMO

PURPOSE: To report on the feasibility of 27-gauge (G) vitrectomy for pediatric patients. METHODS: This study is an international, multicenter, retrospective, interventional case series. Participants were patients 17 years or younger who underwent 27-G vitrectomy for various indications. RESULTS: The records of 56 eyes from 47 patients were reviewed. Mean age was 5.7 ± 5.2 years. Diagnoses included retinopathy of prematurity (Stages 3 with vitreous hemorrhage, 4A, 4B, and 5), Terson's syndrome, traumatic macular hole, posterior capsular opacification, endophthalmitis, and others. Instruments used were the 27-G infusion, 27-G vitreous cutter, 27-G light pipe, and 27-G internal limiting membrane forceps. Instrument bending was noted in one (1.8%) case. There were no cases with intraoperative complications, infusion issues, or postoperative endophthalmitis. There were 67/145 (46%) sclerotomies that required suturing, of which most (51/145) were sutured out of precaution. There were four cases (7.1%) that required conversion to a larger gauge and three cases (5.3%) that developed postoperative hypotony. Mean visual acuity improved from logarithm of the minimum angle of resolution 1.32 (20/420) to 0.72 (20/105), after a mean follow-up of 125.1 days (P = 0.01). Anatomic success was achieved in 96.4% of eyes after a single surgery. CONCLUSION: Twenty-seven-gauge vitrectomy was safe and feasible in selected pediatric vitreoretinopathies. Further studies are warranted to examine indications and outcomes.

RESUMO

PURPOSE OF REVIEW: To review how private equity entities generate profit for investors and ophthalmologists. RECENT FINDINGS: There is a preponderance of private equity acquisitions and consolidation in ophthalmology. These private equity entities generate revenue by growth, profit improvement, and efficient use of capital structure. Physician partners sell their revenue and assets to a private equity entity while retaining a percentage of future profit. In general, a greater percentage going forward, will result in a smaller initial buyout. Partners typically receive payment in the form of cash and stock in the private equity entity, aligning incentives of both parties to grow and succeed. Junior associates and future partners typically do not benefit from the cash buyout but might have opportunity to buy shares in the private equity entity. SUMMARY: The ophthalmology job market has changed significantly with the rise in private equity. Private equity investors profit from organic growth, economies of scale, and future revenue of ophthalmology practices. Ophthalmology partners benefit from often sizeable buyouts and potentially profitable shares in the private equity entity. Junior and future ophthalmologist may be less likely to succeed financially compared with their contemporaries. Some private equity entities will thrive and other may fail, particularly if they are unable to attract talented new ophthalmologists.

RESUMO

PURPOSE: To evaluate the visual outcomes and the affect of timing of surgical repair of fovea-splitting rhegmatogenous retinal detachments. METHOD: A retrospective, consecutive cohort from multiple surgeons at a single center. Fovea status (fovea-on, fovea-splitting, or fovea-off) was classified by preoperative optical coherence tomography. The primary outcome measure was the visual acuity at the last follow-up that was further correlated with the timing of surgical repair. RESULTS: One hundred and ninety-five eyes were included with 62 fovea-on, 65 fovea-splitting, and 68 fovea-off detachments. The mean preoperative logarithm of the minimum angle of resolution visual acuity for fovea-on, fovea-splitting, and fovea-off groups was 0.16 ± 0.21, 0.70 ± 0.56, and 1.67 ± 0.87, respectively (P = <0.001). Mean postoperative logarithm of the minimum angle of resolution visual acuity for fovea-on, fovea-splitting, and fovea-off groups were 0.07 ± 0.13, 0.10 ± 0.15, and 0.20 ± 0.22, respectively (P = <0.001). A statistically significant difference in mean postoperative logMAR visual acuity was found between fovea-off and fovea-on groups (P = 0.003) and between fovea-off and fovea-splitting groups (P = 0.013), however not between fovea-on and fovea-splitting groups (P = 0.827). Visual acuity improved when repair was performed earlier after presentation for fovea-on (R = 0.378, P = 0.002) and fovea-off groups (R = 0.277, P = 0.022), but not for the fovea-splitting group (R = 0.089, P = 0.481). CONCLUSION: We described the favorable visual outcomes of surgery for fovea-splitting rhegmatogenous retinal detachment and correlated these with the timing of surgical repair, which may help guide the management of this urgent, vision-threatening condition.

RESUMO

PURPOSE: Routine use of face masks for patients and physicians during intravitreal anti-vascular endothelial growth factor (VEGF) injections has increased with the emergence of the coronavirus disease 2019 pandemic. This study evaluates the impact of universal face mask use on rates and outcomes of post-injection endophthalmitis (PIE). DESIGN: Retrospective, multicenter, comparative cohort study. PARTICIPANTS: Eyes receiving intravitreal anti-VEGF injections from October 1, 2019, to July 31, 2020, at 12 centers. METHODS: Cases were divided into a "no face mask" group if no face masks were worn by the physician or patient during intravitreal injections or a "universal face mask" group if face masks were worn by the physician, ancillary staff, and patient during intravitreal injections. MAIN OUTCOME MEASURES: Rate of endophthalmitis, microbial spectrum, and visual acuity (VA). RESULTS: Of 505 968 intravitreal injections administered in 110 547 eyes, 85 of 294 514 (0.0289%; 1 in 3464 injections) cases of presumed endophthalmitis occurred in the "no face mask" group, and 45 of 211 454 (0.0213%; 1 in 4699) cases occurred in the "universal face mask" group (odds ratio [OR], 0.74; 95% confidence interval [CI], 0.51-1.18; P = 0.097). In the "no face mask" group, there were 27 cases (0.0092%; 1 in 10 908 injections) of culture-positive endophthalmitis compared with 9 cases (0.004%; 1 in 23 494) in the "universal face mask" group (OR, 0.46; 95% CI, 0.22-0.99; P = 0.041). Three cases of oral flora-associated endophthalmitis occurred in the "no face mask" group (0.001%; 1 in 98 171 injections) compared with 1 (0.0005%; 1 in 211 454) in the "universal face mask" group (P = 0.645). Patients presented a mean (range) 4.9 (1-30) days after the causative injection, and mean logarithm of the minimum angle of resolution (logMAR) VA at endophthalmitis presentation was 2.04 (~20/2200) for "no face mask" group compared with 1.65 (~20/900) for the "universal face mask" group (P = 0.022), although no difference was observed 3 months after treatment (P = 0.764). CONCLUSIONS: In a large, multicenter, retrospective study, physician and patient face mask use during intravitreal anti-VEGF injections did not alter the risk of presumed acute-onset bacterial endophthalmitis, but there was a reduced rate of culture-positive endophthalmitis. Three months after presentation, there was no difference in VA between the groups.

RESUMO

PURPOSE: To evaluate the refractive outcomes of sutureless intrascleral fixation of intraocular lens with pars plana vitrectomy. METHOD: A retrospective, consecutive cohort from multiple surgeons of a single center. Primary outcomes included spherical equivalent (SEQ) and change in SEQ (ΔSEQ) from preoperative intraocular lens power calculations. Secondary outcomes included refractive outcomes of fixation at 1.5 mm, 2 mm, and 2.5 mm posterior to the limbus. RESULTS: In total, 84 eyes of 80 patients were included. Preoperative logarithm of the minimum angle of resolution visual acuity was 1.21 ± 0.68 (20/320). The mean follow-up time was 2.33 ± 1.36 years. At 3 months, SEQ was -0.50 ± 1.59 D and ΔSEQ was 0.58 ± 1.49 D. At 1 year, SEQ was -0.55 ± 1.32 D and ΔSEQ was 0.39 ± 1.42 D. At the last follow-up, logarithm of the minimum angle of resolution visual acuity was 0.34 ± 0.34 (20/40), SEQ was -0.51 ± 1.44 D, and ΔSEQ was 0.57 ± 1.27 D. There was no difference between SEQ or ΔSEQ throughout follow-up (P = 0.97 and P = 0.96, respectively). At fixation distances more posterior to the limbus, mean ΔSEQ was more hyperopic at 3 months, 1-year, and the last follow-up (P = 0.02, P = 0.01, and P = 0.006, respectively). CONCLUSION: Refractive outcomes for sutureless intrascleral fixation of intraocular lens with pars plana vitrectomy were favorable and showed stability postoperatively. These results may aid surgeons achieve better desired refractive outcomes for this technique.

RESUMO

PURPOSE: To evaluate the retinal periphery in patients with idiopathic juxtafoveal telangiectasis or macular telangiectasis Type 2 (MacTel2), using widefield fluorescein angiography. METHODS: Single-center, retrospective, observational case series of 50 eyes of 50 patients with MacTel2 and 50 eyes of 50 age-matched controls. RESULTS: Thirty-seven eyes in the MacTel2 group (74%) showed peripheral capillary nonperfusion or dropout, compared with 37 eyes in the control group (74%, P = 1.0). Morphologically, the MacTel2 group trended toward having a higher proportion of pruning-type capillary dropout (44%) compared with controls (28%), but this was not statistically significant (P = 0.12). Patients with MacTel2 had a higher incidence of microaneurysms compared with controls (MacTel2 56%; controls 42%; P = 0.048), independent of age or systemic risk factors. There was no difference in the incidence of venous-venous shunts (MacTel2 10%; controls 10%; P = 1.0), arteriovenous shunts (MacTel2 14%; controls 18%; P = 0.60), venous tortuosity (MacTel2 60%; controls 66%; P = 0.58), or arterial tortuosity (MacTel2 54%; controls 68%; P = 0.20), which was mild in most cases. CONCLUSION: We note a high incidence of peripheral vascular and retinal findings in both patients with MacTel2 and age-matched controls, using widefield fluorescein angiography. Patients with MacTel2 had significantly more microaneurysms, independent of age or other systemic risk factors.

RESUMO

PURPOSE: To evaluate the clinical course of patients with neovascular age-related macular degeneration (nAMD) after developing endophthalmitis during their treatment with intravitreal injections. METHODS: Multicenter, retrospective series. RESULTS: From April 2013 to October 2018, 196,598 intravitreal anti-vascular endothelial growth factor (VEGF) injections were performed, with 75 cases of endophthalmitis (incidence 0.0381%). There was no association between intravitreal anti-VEGF drug (P = 0.29), anesthetic method (P = 0.26), povidone concentration (P = 0.22), or any intraprocedure variable and endophthalmitis incidence. Seventy-two patients (96%) were treated with intravitreal tap and inject , while 3 underwent immediate pars plana vitrectomy. After endophthalmitis resolution, 17 patients (22.7%) were not re-treated for nAMD (in 10 cases due to inactive disease; follow-up, 115 ± 8.4 weeks). Patients required less frequent anti-VEGF injections after infection (7.4 ± 0.61 weeks vs. 11.5 ± 1.8 weeks; P = 0.004). Preinfection logarithm of the minimum angle of resolution visual acuity was 0.585 ± 0.053 (∼20/77). It worsened with endophthalmitis (1.67 ± 0.08, ∼20/935; P < 0.001) and again on postendophthalmitis treatment day 1 (1.94 ± 0.064; count fingers; P < 0.001), but improved after reinitiating nAMD therapy (1.02 ± 0.11; ∼20/209; P < 0.001). Better visual acuity on postendophthalmitis week 1 (P = 0.002) and reinitiation of nAMD treatment (P = 0.008) were associated with better final visual acuity, and streptococcal culture with worse visual acuity (P = 0.028). The postendophthalmitis treatment interval was associated with the anti-VEGF drug used (aflibercept = ranibizumab > bevacizumab; P < 0.001). CONCLUSION: Patients with nAMD required fewer injections after endophthalmitis, suggesting a biological change in disease activity. Neovascular age-related macular degeneration became quiescent in 13.3% of eyes. Most achieved better outcomes with anti-VEGF reinitiation.

RESUMO

PURPOSE: To determine whether haptic flanging during 27-gauge sutureless intrascleral fixation of intraocular lenses (IOLs) increases IOL stability and to report the short-term clinical outcomes of sutureless intrascleral surgery using 27-gauge trocar cannulas with haptic flanging. METHODS: Retrospective surgical case series using live and cadaveric human eyes. RESULTS: In the cadaveric experiment using five eyes, flanged haptics required more force to dislocate the IOL compared with unflanged haptics (14 ± 4 vs. 3 ± 1 g, P = 0.03). The clinical series included 52 eyes from 52 patients. The average age at the time of surgery was 73 ± 14 years, with a mean follow-up of 27 ± 19 weeks. The most common indication for surgery was IOL dislocation/subluxation (n = 43, 83%). Mean visual acuity improved from 20/140 preoperatively to 20/50 at postoperative Month 1 (P < 0.001). The most common postoperative issue was intraocular pressure elevation (n = 12, 23%). Two patients (4%) needed a reoperation for IOL dislocation. CONCLUSION: Haptic flanging during 27-gauge sutureless intrascleral surgery creates a more stable scleral-fixated IOL compared with the traditional unflanged technique based on a cadaveric human eye study. In addition, this variation of sutureless intrascleral surgery seems safe and effective for patients who require secondary IOLs.

RESUMO

PURPOSE: To describe surgical outcomes and structural characteristics of intraocular lenses (IOLs) implanted with transconjunctival sutureless intrascleral (SIS) fixation in human eyes. DESIGN: Retrospective interventional surgical case series involving live and cadaveric human eyes. METHODS: In this study, we investigated the surgical outcomes and structural anatomy of secondary IOLs implanted with the SIS technique in human eyes. All cases involving SIS IOL fixation performed at a single academic center from January 1, 2012, through July 30, 2016, were reviewed to describe the surgical technique, common indications, clinical outcomes, and the rate of common operative complications. To investigate the structure of SIS-fixated IOLs in vivo, slit-lamp biomicroscopy, ultrasound biomicroscopy, and intraoperative endoscopy were analyzed to describe anatomical outcomes. The primary anatomical outcomes were the optic pupillary centration and location of haptic externalization. Results were correlated with cadaveric human eyes that underwent the SIS-IOL technique. Cadaveric eyes were imaged and analyzed using high-resolution photography for centration, stress measurements at the haptic-optic junction, and qualitative descriptors of IOL optic and haptic position. RESULTS: A total of 122 consecutive patients who underwent IOL placement using SIS technique were included in the study with mean follow-up of 1.52 years (range, 0.4-4.5 years). The majority (75%) of patients received a new 3-piece IOL for primary aphakia or after IOL exchange. The other patients (25%) had a dislocated 3-piece IOL that was rescued using the SIS technique. Preoperative mean Snellen visual acuity was 20/633 (logarithm of the minimum angle of resolution = 1.501). At the final visit, the mean best-corrected visual acuity was 20/83 (logarithm of the minimum angle of resolution = 0.6243) and final mean spherical equivalent was -0.57 diopters. The most common complications were vitreous hemorrhage (22% of eyes), which resolved spontaneously in most cases, and cystoid macular edema. The rates of IOL dislocation, IOL decentration, haptic erosion, IOL tilting, iris capture, and endophthalmitis were low. Intraoperative endoscopy and ultrasound biomicroscopy demonstrated a securely fixated IOL and well-centered optic without iris or ciliary body touch. Structural study of cadaveric eyes confirmed IOL optic and haptic anatomy observed during live human surgery. The ab interno haptic insertion was the anterior pars plana, away from the iris, ciliary processes and ora serrata. The degree of haptic externalization was correlated with the degree of strain on the haptic-optic junction. The angle of the haptic-optic junction in SIS-fixated IOLs (33.97°) was not significantly different compared with overlaid native nonfixated IOL (32.93°) but increased slightly with degree of haptic tip externalization (36.26 and 39.16 for 2 and 3 mm haptic externalizations, respectively). CONCLUSION: In this comprehensive study, we demonstrate the surgical outcomes achieved with SIS fixation of IOLs. Surgical and postoperative complications do occur, albeit at a low rate, and can effectively be managed with excellent anatomical and visual outcomes. The structural and anatomical data in this study may help guide SIS placement and optimize long-term surgical results.

RESUMO

PURPOSE: To investigate the efficacy of the intravitreal dexamethasone implant as the treatment for recalcitrant macular edema after successful rhegmatogenous retinal detachment repair. METHODS: A retrospective review of the medical records was performed on 17 consecutive patients (17 eyes) with recalcitrant macular edema associated with rhegmatogenous retinal detachment repair who were treated with a single or multiple injections of an intravitreal dexamethasone 0.7-mg implant (Ozurdex; Allergan Inc) at two centers. Main outcomes of the study were change in logarithm of the minimum angle of resolution visual acuity, measurement of central foveal thickness, and macular cube volume as measured by spectral domain optical coherence tomography and frequency of complications. RESULTS: The mean age was 67 years (range, 51-78 years). All 17 patients received previous topical therapy and 12 of them had previous administration of intravitreal triamcinolone with persistence of macular edema. Baseline mean best-corrected visual acuity was 20/100 (logarithm of the minimum angle of resolution 0.75; range, 0.18-1.3 ±0.37) in the affected eyes. There was a statistically significant improvement in best-corrected visual acuity at 1 month (P < 0.001) and 3 months (P = 0.01). Mean baseline central foveal thickness was 505 µm, and mean macular cube volume was 10.62 mm. There was a statistically significant decrease in central foveal thickness and macular cube volume at 1 month (505-290 µm, P = 0.013 and 10.62-9.13 mm, P < 0.0001) and 3 months (P = 0.01). All patients developed recurrence of macular edema at 3 months, which required retreatment. The average number of implants was 4 (range, 1-14). No adverse effects such as retinal detachment or endophthalmitis occurred. Two patients experienced an increase in intraocular pressure that was controlled with topical therapy. CONCLUSION: Macular edema that occurs in eyes after successful repair of rhegmatogenous retinal detachment can be chronic and recalcitrant, and may be successfully and safely treated with the dexamethasone intravitreal implant.

RESUMO

PURPOSE: To report the clinical presentation, microbiologic spectrum, and visual outcomes associated with acute-onset infectious endophthalmitis undergoing therapeutic pars plana vitrectomy. METHODS: Multicenter interventional retrospective noncomparative consecutive case series. Billing records were reviewed to identify all charts for patients undergoing pars plana vitrectomy within 14 days of diagnosis of acute-onset infectious endophthalmitis over a 4-year period at 5 large tertiary referral retina practices. Statistical analysis was performed to assess for factors associated with visual outcomes. RESULTS: Seventy patients were identified. The most common clinical setting was postcataract surgery (n = 20). Only 3 patients (4.3%) presented with 20/400 or better visual acuity (VA). Although most of the patients initially underwent vitreous tap and intravitreal antibiotic injection (n = 47, 67.1%), all patients eventually underwent pars plana vitrectomy within 14 days of presentation with 68.5% (48/70) of patients undergoing pars plana vitrectomy within 48 hours of presentation. Positive intraocular cultures were obtained in 56 patients (80%). The most common identified organism was Streptococcus sp (n = 19). Visual acuity at last follow-up was 20/400 or better in 19 patients (27.1%). Three patients underwent evisceration or enucleation (4.3%). Last recorded postoperative VA (mean LogMAR 1.99 ± 0.94, Snellen VA equivalent finger count) improved from presenting VA (mean LogMAR 2.37 ± 0.38, Snellen VA hand motions) (P ≤ 0.001). There was no statistically significant correlation between the underlying etiology or the timing of surgery with this VA outcome. CONCLUSION: Although less than one-third of patients achieved 20/400 or better VA, this VA often improved significantly from presenting VA.

RESUMO

PURPOSE: To report the visual acuity outcomes after pars plana vitrectomy for delayed vitreoretinal sequelae of infectious endophthalmitis. All eyes were initially treated with intravitreal antibiotics (Abx). METHODS: Multicenter, retrospective, consecutive case series. RESULTS: Forty-two eyes met the study criteria. The mean follow-up was 48 weeks (SD ± 61.8). Mean interval from Abx to pars plana vitrectomy was 13 weeks (SD ± 14.3, range 2-70). Indications for pars plana vitrectomy included vitreous opacities (VO) (n = 22), epiretinal membrane (n = 9), and retinal detachment (n = 11). LogMAR visual acuity improved from 1.87 (Snellen equivalent: 20/1,482) preoperatively to 1.35 (Snellen equivalent: 20/447) at final evaluation (P < 0.001). LogMAR visual acuity improved significantly for patients with vitreous opacities (P < 0.01) and retinal detachment (P = 0.02) but not for patients with epiretinal membranes (P = 0.08). CONCLUSION: Patients with infectious endophthalmitis can gain vision if they have a pars plana vitrectomy for delayed sequelae such as vitreous opacities or for retinal detachment.

RESUMO

PURPOSE: To evaluate the aftermarket efficacy of ocriplasmin for vitreomacular adhesion (VMA) and identify the frequency and duration of structural changes on optical coherence tomography. METHODS: The authors conducted a retrospective case series of 36 eyes treated with ocriplasmin for symptomatic VMA at a single center between February 2013 and September 2013. Eyes were evaluated for release of VMA at 1 month postinjection, preinjection adhesion size, postinjection closure of macular hole, presence of subretinal fluid after release of adhesion, size of subretinal fluid, outer retinal structural change, and visual acuity at 1 month, 6 months, and 1 year. RESULTS: Fifteen eyes (42%) had complete release of VMA at 1 month postinjection, and 78% of eyes had closure of the macular hole. Eyes that did not have an epiretinal membrane that had a smaller initial adhesion size and a smaller macular hole size were more likely to have complete release of VMA. Subretinal fluid was present after release in 73.3% of treated eyes, and ellipsoid zone changes were present in 66.7% of treated eyes. At the end of 1 year, complete resolution of subretinal fluid occurred in 87% of treated eyes with only trace subretinal fluid remaining in 2 eyes. Complete resolution of ellipsoid zone changes was found in all eyes. Best-corrected visual acuity improved throughout the first year after treatment. CONCLUSION: Ocriplasmin is effective in the treatment of patients with symptomatic VMA. Results can be improved with patient selection based on specific criteria. Subretinal fluid and ellipsoid zone changes are common after treatment but mostly resolve over 1 year.

RESUMO

PURPOSE: Widefield photography and angiography provide access up to 200-degrees of the retinal periphery. The range of normal peripheral findings has not been characterized, yet is relevant to studies addressing putative peripheral retinal vascular pathology. METHODS: This study was an observational retrospective cohort study. Adult patients with epiretinal membrane or choroidal nevi who underwent imaging with Optos 200 MA/200Tx were included. Dye transit times, peripheral arteriovenous shunting, presence of vessels crossing the horizontal raphe, right angle vessels, terminal networks, absence of capillary detail, ground glass hyperfluorescence, peripheral drusen, and microaneurysms were evaluated. RESULTS: Fifty-eight eyes of 31 patients met inclusion criteria. Mean peripheral arterial filling time was 8.65 ± 2.54 seconds (range 3-15 seconds). One or more peripheral anomalies were noted in all patients (P < 0.01). The prevalences of findings were: arteriovenous shunting (0.00%), vessels crossing the horizontal raphe (44.83%), right angle vessels (70.69%), terminal networks (77.59%), absence of capillary detail (98.28%), ground glass hyperfluorescence (87.93%), drusen (34.48%), and microaneurysms (41.38%). CONCLUSION: There was a high prevalence of peripheral vascular anatomic variations in eyes expected to have normal peripheral retinal vasculature. These findings may provide a reference for future studies addressing putative pathologic peripheral angiographic findings.

RESUMO

PURPOSE: We sought to assess the clinical outcomes and complications of two approaches to scleral fixation of intraocular lenses (IOLs): transconjunctival fixation through trocar cannulas and fixation using scleral tunnels created with a microvitreoretinal (MVR) blade. METHODS: This retrospective chart review was comprised of 23 eyes that received scleral fixation of a three-piece IOL with concurrent pars plana vitrectomy between June 2012 and June 2014. Scleral fixation was performed either by transconjunctival fixation through trocar cannulas (cannula fixation) or by the creation of scleral tunnels using an MVR blade (tunnel fixation). The preoperative and postoperative corrected distance visual acuities (CDVA), spherical equivalents (SE), and complications were evaluated. RESULTS: 15 cannula fixations and 8 tunnel fixations were performed. Mean follow-up was 353 days (Range: 94 - 790 days). Fifteen IOLs were fixated 2 mm posterior to the limbus. Seven IOLs were fixated 1.5 mm posterior to the limbus, and one IOL was fixated 0.75 mm posterior to the limbus. Mean preoperative CDVA was logMAR 1.17 (Snellen 20/297), and mean postoperative CDVA was logMAR 0.37 (Snellen 20/47) (p <0.0001). At last follow-up, none of the IOLs have dislocated or subluxed and there has been no erosion of the subconjunctival haptics. CONCLUSIONS: Scleral fixation of IOLs using trocar cannulas or scleral tunnels is an effective surgical option for the treatment of aphakia or IOL dislocation. Both techniques result in significant visual improvement with minimal postoperative complications.

RESUMO

PURPOSE: To report an association between central serous chorioretinopathy (CSCR) and exogenous testosterone therapy. METHODS: This is a retrospective case series from two institutions. Patients who presented with fluorescein angiography and optical coherence tomography findings consistent with CSCR were included. All patients were concurrently being treated with exogenous testosterone therapy and lacked other known risk factors for CSCR. RESULTS: Nine patients presented with CSCR after beginning exogenous testosterone therapy. Two patients stopped therapy with resolution of symptoms and subretinal fluid. CONCLUSION: Exogenous testosterone may be an independent risk factor for the development of CSCR.
