RESUMO

OBJECTIVE: To report the clinical outcomes of a 25-gauge, beveled-tip, 10,000 cuts-per-minute (cpm) microincisional vitrectomy surgery (MIVS) system. METHODS: Prospective case series of eyes undergoing primary pars plana vitrectomy (PPV) for common vitreoretinal indications. Main outcome measures were: rate of achieving surgical objectives, operative times, number of surgical steps, use of ancillary instruments, corrected distance visual acuity (CDVA), and adverse events (AE). RESULTS: The surgical objectives were achieved in all eyes. Mean total operative time (TOT), core, shave and total vitrectomy times were 1891 ± 890, 204 ± 120, 330 ± 320, 534 ± 389 s, respectively. Mean number of surgical steps was 4.3 ± 1.5. Mean number of ancillary instruments used was 4.5 ± 1.9. Mean CDVA improved by 0.53 ± 0.56 logMAR units (P < 0.001) 3 months postoperatively. AE included elevated IOP (8%), hypotony (6%), and re-detachment (2%). Majority (82%) had no postoperative discomfort. The number of surgical steps demonstrated a positive correlation with TOT (p < 0.05), number of ancillary instruments used (p < 0.05), and postoperative Day 1 IOP (p < 0.05). The number of times ancillary instrumentation was used demonstrated a positive correlation with TOT (p < 0.05). CONCLUSION: Beveled-tip, 10,000 cpm MIVS system effectively and safely performs common VR procedures of varying complexity and may reduce operative times and use of ancillary instrumentation.

RESUMO

PURPOSE: To evaluate the safety and efficacy of dexamethasone intravitreal implant 0.7 mg (DEX) compared with laser photocoagulation in patients with diabetic macular edema (DME). PATIENTS AND METHODS: This Phase 3, multicenter, randomized, efficacy evaluator-masked, parallel-group, 12-month clinical study enrolled adults in China and the Philippines with reduced visual acuity secondary to fovea-involved DME in the study eye. Participants were randomized 1:1 to study eye treatment with laser photocoagulation every 3 months as needed (n = 139) or DEX every 5 months (n = 145). The main efficacy measures were best-corrected visual acuity (BCVA), central retinal thickness (CRT), and leakage area. The primary endpoint was the average change in BCVA from baseline over 12 months (area-under-the-curve method). Preplanned subgroup analyses evaluated outcomes in Chinese patients. RESULTS: Mean average change in BCVA from baseline during the study (letters) was 4.3 with DEX (n = 145) versus 1.4 with laser (n = 127) overall (P = 0.001) and 4.6 with DEX (n = 129) versus 0.6 with laser (n = 113) in Chinese patients (P < 0.001). At Month 12, mean change in CRT from baseline was -209.5 µm with DEX versus -120.3 µm with laser (P < 0.001) and mean change in total leakage area from baseline was -8.367 mm2 with DEX versus -0.637 mm2 with laser (P < 0.001). The most common treatment-emergent adverse events in the DEX group were increased intraocular pressure and cataract. CONCLUSION: DEX administered every 5 months provided significantly greater improvement in BCVA, CRT, and total leakage area compared with laser treatment. DEX demonstrated an acceptable safety profile, consistent with an intraocular corticosteroid, and similar to that reported in completed global registration studies.

RESUMO

PURPOSE: To evaluate the efficacy and safety of a hinged pupil expansion device (PED) in eyes with small pupils undergoing phacoemulsification. METHODS: In this prospective, multicenter, interventional case series of 57 eyes with suboptimal pharmacologic pupil dilation (<5 mm diameter), a hinged PED (I-Ring, Beaver-Visitec International, Waltham, MA) was applied to facilitate surgical visualization during cataract surgery. The pupil diameters (PD) were measured at different stages of the procedure and at the 1-month follow-up visit. Rate of successful intraoperative PED deployment, pupil size, and shape were assessed. RESULTS: The mean patient age was 70.5 ± 12.1 years. The I-Ring PED was successfully applied in all eyes. The mean PD at various stages were 4.1 ± 1.1 mm (dilation with eye drops only preoperatively), 4.3 ± 1.1 mm (dilation after intracameral epinephrine and ophthalmic viscoelastic device), 6.80 ± 0.00 mm (with PED applied), and 5.7 ± 1.1 mm (end of surgery). A statistically significant difference (P < 0.001) was observed between the mean PD with intracameral medications and with PED application. Postoperative circular pupil was observed in 54 of 57 eyes (94.7%) and the mean eccentricity index (n = 57 eyes) was 0.11 ± 0.22. No significant adverse events were observed. CONCLUSION: The I-Ring PED safely and effectively provided and maintained adequate pupil expansion and surgical visualization in eyes with small pupils undergoing cataract surgery. Postoperatively 95% of eyes attained circular pupils. This hinged PED is an additional instrumentation option for the safe and effective expansion of inadequately sized pupils during cataract surgery.

RESUMO

OBJECTIVE: To compare the effectiveness, procedure time and safety outcomes of two different intravitreal injections (IVI) techniques. METHODS: This was a prospective, single-center, randomized clinical trial of 200 adult eyes receiving intravitreal medications for various indications. Eyes were assigned (1:1) to undergo IVI using either an intravitreal injection guide (IIG) (n= 100) or conventional dual blade speculum plus surgical caliper (DBS) (n=100). All IVI were administered using a 30-gauge needle placed 4 mm posterior to the inferior limbus. The main outcome measures were rate of successful IVI administration, procedure time (seconds) as measured by a stopwatch from application to removal of IIG or DBS, patient preference for IVI technique and adverse events. RESULTS: The two groups were similar in terms of mean age (P=0.398), laterality (P=0.671), indication for treatment (P=0.175) and medication type (P=0.489). All IVI procedures were successfully completed in both groups. The mean procedure time was shorter using the IIG (9.94 ± 2.87 seconds) versus DBS (21.85 ± 7.25 seconds) technique (P ≤ 0.01). The incidence of post-injection subconjunctival hemorrhage was higher when the DBS was applied (OR = 2.35, 95% CI = 1.22-4.53). Patients with previous history of IVI preferred the IIG over the DBS. No other injection-related adverse events were observed in both groups. CONCLUSION: DBS and IIG techniques are similarly effective and safe for the administration of intravitreal medications. The IIG appears to significantly reduce procedure time, be associated with a lower incidence of subconjunctival hemorrhage and engender better patient acceptance. CLINICAL TRIAL REGISTRATION: ClinicalTrials.gov (NCT04455399).

RESUMO

PURPOSE: To evaluate the rotational stability of the Precisight multicomponent intraocular lens (MCIOL) following primary implantation and after enhancement procedures. PATIENTS AND METHODS: Prospective, single-center study of eyes that underwent routine cataract surgery with implantation of a non-toric MCIOL, (Precisight, InfiniteVision, Optics, Strasbourg, France). The axis of the MCIOL was measured with a line bisecting the two dialing holes in the front lens. Intraoperative orientation was determined using a digital surgical guidance system while the postoperative orientation was determined using slit-lamp imaging. Two populations were analyzed: eyes that only underwent cataract surgery (PRIM) and eyes that also underwent enhancement (ENH), consisting of surgical front optic exchange. Both populations had 3 observation visits: first implantation (P-Op); 3 months (3mo) and 6 months (6mo) after primary surgery. The ENH group had an additional fourth visit that corresponded to the enhancement surgery (E-Op). The main outcome measure was mean absolute change in MCIOL orientation (degrees). The effects of axial length (AL) and anterior chamber depth (ACD) on IOL rotational stability were examined. RESULTS: Thirty-three eyes received MCIOL of which 29 had usable orientation images. Of these, 12 were in the PRIM group and 17 underwent ENH. Regarding the mean absolute rotation, among PRIM eyes, P-Op to 3mo was 3.03±2.45 degrees; P-Op to 6mo, 2.28±1.54 degrees; and 3-6mo, 2.37±1.56 degrees. Among the ENH eyes, P-Op to 3mo was 3.09±1.68; E-Op to 6mo, 2.71±3.30 and P-Op to 6mo, 3.62±3.42. There were no significant differences in the IOL rotation. There were no statistical differences in rotational stability between the ENH and PRIM groups. There was no correlation between IOL rotation and AL or ACD. CONCLUSION: Precisight appears to be rotationally stable. The enhancement procedure does not affect rotational stability.

RESUMO

BACKGROUND: Uveitis is a group of intraocular inflammatory diseases whose primary treatment involves immunosuppression. Although corticosteroids (CSs) remain the mainstay therapy, sirolimus is among the recently studied immunomodulatory drugs for treating noninfectious uveitis (NIU). OBJECTIVE: The aim of this review was to assess and summarize the updated evidence on the outcomes of treatment with sirolimus for NIU. MATERIALS AND METHODS: Two reviewers conducted a systematic search on November 5, 2018, of electronic databases (EMBASE, MEDLINE, and The Cochrane Library) and clinical trial registers having no restrictions on language or publication date. The primary outcome was uveitis activity as measured by vitreous haze (VH), while the secondary outcomes included central macular thickness (CMT), best-corrected visual acuity (BCVA), CS-sparing effect, IOP elevation, and other adverse events. A meta-analysis was conducted on selected studies with appropriate clinical and methodological homogeneity. RESULTS: Seven studies were included and reviewed. Four randomized clinical trials were eligible for meta-analysis: SAVE 2013, One-year outcomes of the SAVE study, SAVE 2 2016, SAKURA 2016. The pooled proportions of inflammation control (VH improvement) were 38% (95% CI 16.19%-62.66%) during a 6-month follow-up and 49.97% (95% CI 16.19%-83.03%) during a 6- to 12-month follow-up with the latter showing a significantly higher response rate (p=0.0472). BCVA improvement was 62.2% (95% CI 33.17%-87.11%) during a 6-month follow-up and 56.86% (95% CI 20.91%-89.05%) during a 6- to 12-month follow-up with no significant difference between the two (p=0.3705). Increased IOP remained at 7.11% (95% CI 3.46%-12.68%) for both a 6-month follow-up and up to a 12-month follow-up duration. The CS-sparing effect of sirolimus was also well demonstrated. A reduction in CMT was observed, and only minor drug-related adverse events were reported in all the studies reviewed. CONCLUSION: This review provided evidence that sirolimus is a promising treatment option for controlling inflammatory activity, improving visual acuity, and sparing CS use with minor adverse events for NIU.

RESUMO

PURPOSE: To compare surgical parameters among eyes undergoing laser-assisted cataract surgery (LACS) using different lens fragmentation patterns (LFP). METHODS: Prospective, randomized, unmasked clinical trial. One-hundred eyes underwent LACS and were randomly assigned to 1 of 3 LFP treatment groups: (1) laser capsulotomy only; no lens fragmentation (NLF) (n = 34); (2) three-plane chop (TPC) (n = 33); and, (3) pie-cut pattern (PCP) fragmentation (n = 33). Prechop phacoemulsification (PHACO) was performed on all eyes using the same femtosecond (FS) laser and active-fluidics PHACO machine. MAIN OUTCOME MEASURES: FS laser dock time (s), PHACO time (s), PHACO power (%), cumulative dissipated energy (CDE) (%-s), irrigating fluid volume, and operative time. RESULTS: The 3 treatment groups were comparable in terms of patient age (P = 0.164) and nuclear density (P = 0.669). FS dock time was higher in the PCP group (184.18 ± 25.86) compared to the TPC (145.09 ± 14.15) group (P < 0.001). PHACO time was significantly shorter in the PCP (23.19 ± 17.20 s) compared to TPC (35.27 ± 17.70) and NLF (46.15 ± 23.72) groups (P < 0.001). PHACO power was lower in the PCP (11.81 ± 3.71) compared to the NLF (14.41 ± 1.88) and TPC (14.04 ± 2.46) groups (P < 0.001). CDE was lower in the PCP (2.85 ± 2.32) compared to NLF (6.55 ± 3.32) and TPC (6.55 ± 5.45) groups (P < 0.001). Fluid volumes and operative times were similar. CONCLUSION: LFP can influence PHACO surgical parameters. Extensive fragmentation patterns such as PCP appear to lower PHACO time, power, and CDE and may potentially reduce the risk of PHACO related complications.

RESUMO

PURPOSE: Eyes that have undergone phacoemulsification with implantation of a multicomponent intraocular lens (MCIOL) may further undergo an enhancement procedure for correction of residual refractive errors. The enhancement procedure is accomplished by exchanging the front lens used in the primary surgery with another lens containing the correct dioptric power. We evaluated the efficacy and safety of enhancement procedures among eyes that received an MCIOL. METHODS: A total of 25 eyes that had undergone phacoemulsification with implantation of an MCIOL were found to have a residual error of refraction (spherical equivalent ≥0.75 D) 3 months after primary cataract surgery, and underwent further enhancement surgery. The main study outcomes were uncorrected and corrected distance visual acuity, subjective refraction, anterior-chamber depth, pachymetry, and endothelial cell count. RESULTS: There was a statistically significant improvement in uncorrected distance visual acuity of approximately two lines after enhancement surgery (0.20±0.20-0.02±0.08 logMAR, P<0.001) and a significant decrease in residual spherical equivalent from 1.3±1.1 D to 0±0.38 D (P<0.001). There were no statistically significant changes in pre- and postenhancement corrected distance visual acuity, anterior-chamber depth, pachymetry, or keratometry. There was a statistically significant decrease (2.6%) in endothelial cell count (P<0.01), which could have been endothelial equilibration from the primary procedure. All enhancement surgeries were uneventful, and no major complications were observed. CONCLUSION: The MCIOL-enhancement procedure demonstrates statistical and clinical improvement in uncorrected distance visual acuity and correction of postoperative refractive errors. The Precisight IOL may be a useful choice for patients with high risk of having significant residual refractive errors after primary cataract surgery.

RESUMO

Diabetic macular oedema is the most common cause of diabetic retinopathy-induced vision loss. Efficacy of anti-vascular endothelial growth factor therapy in diabetic macular oedema has been demonstrated in randomized controlled trials. An Asian-specific guideline for diabetic macular oedema treatment is needed as patients in Asia tend to present with far more advanced disease than seen elsewhere in the world. Previous reviews of diabetic macular oedema management lacked a broader assessment of anti-vascular endothelial growth factor treatment choices and newer trials. Recent clinical trial data allow head-to-head comparisons between the different anti-vascular endothelial growth factor agents and treatment regimens. This review aims to summarize the clinical evidence related to various treatment regimens for clinicians, with a focus on anti-vascular endothelial growth factor therapies, and to provide guidance on the treatment of diabetic macular oedema in Asian patients.

RESUMO

PURPOSE: To compare size, circularity, and centration outcomes of continuous curvilinear capsulorhexis (CCC) performed with or without assistance from the VERUS ophthalmic caliper (Mile High Ophthalmics, Denver, CO). METHODS: This was a multicenter retrospective consecutive case controlled series review. RESULTS: Data from 40 consecutive cases using the VERUS device for CCC were compared to 40 consecutive cases with standard manual CCC. VERUS-assisted CCC size, circularity, and centration were closer to target compared to that of manual only procedures (P < .05). The average time from initiation to completion of the capsulotomy was shorter with manual (40 ± 11 seconds) compared to VERUS-assisted (71 ± 13 seconds) cases (P < .0001). CONCLUSIONS: The VERUS ophthalmic caliper is effective at improving size, circularity, and centration of the CCC in a time-efficient manner when compared to manual procedures performed without VERUS guidance.

RESUMO

PURPOSE: To evaluate the occurrence, management, and clinical significance of increases in intraocular pressure (IOP) in patients with diabetic macular edema treated with dexamethasone intravitreal implant (DEX implant). METHODS: Randomized, multicenter, 3-year, Phase III study. Patients (N = 1,048) with diabetic macular edema were randomized to DEX implant 0.7-mg, DEX implant 0.35-mg, or sham procedure with retreatment allowed at ≥6-month intervals (seven injections maximum). RESULTS: In the DEX implant 0.7-mg, DEX implant 0.35-mg, and sham groups, respectively, ≥10-mmHg IOP increases from baseline occurred in 27.7%, 24.8%, and 3.7% of patients, and their frequency did not increase with repeat injections. IOP-lowering medication was used by 41.5%, 37.6%, and 9.1% of patients. Only one patient (0.3%) in each DEX implant group had filtering surgery to manage a steroid-induced IOP increase. Among DEX implant 0.7-mg-treated patients with and without a ≥10-mmHg IOP increase, 21.9% (21 of 96) and 22.4% (57 of 255), respectively, achieved ≥15-letter best-corrected visual acuity gain at the end of the study, and mean average change in central retinal thickness from baseline was -127 µm and -106 µm, respectively. CONCLUSION: DEX implant demonstrated clear benefit of treatment despite increases in IOP. Sequential implants had no cumulative effect on IOP.

RESUMO

PURPOSE: To compare the anatomic and refractive outcomes in eyes having phacoemulsification with 1 of 3 clear corneal incision (CCI) closure methods. SETTING: Ambulatory surgical center, Makati, Philippines. DESIGN: Prospective randomized clinical trial. METHODS: Patients having phacoemulsification cataract surgery had wound closure using no additional treatment (control), a single 10-0 nylon suture, or a liquid adhesive ocular bandage (Ocuseal). The main outcome measures were wound-edge closure rates, surgically induced astigmatism (SIA), foreign-body sensation, and intraocular pressure (IOP) 1, 3, 5, 7, and 14 days postoperatively. RESULTS: The study evaluated 90 eyes. There was a significant improvement in wound-edge closure rates in the suture group and the ocular bandage group compared with the control group (P<.001). A significant increase in SIA occurred in the sutured group but not in the control or ocular bandage groups (P<.001). The ocular bandage group had significantly less foreign-body sensation than the control and suture groups (P<.001). There were no significant differences in IOP between the groups (P=.515). CONCLUSIONS: The liquid adhesive ocular bandage resulted in improved wound-edge closure, reduced SIA, and diminished foreign-body sensation. Suturing was associated with improved wound-edge closure but increased SIA and foreign-body sensation. Unsutured incisions led to delayed wound-edge closure and increased foreign-body sensation.

RESUMO

UNLABELLED: PURPOSE FOR REVIEW: Phacoemulsification is the preferred method for cataract surgery in the developed world. The number of phacoemulsification procedures performed annually is expected to increase as the population ages. Femtosecond cataract surgery offers several surgical advantages over conventional phacoemulsification and has already attained commercial application in some countries. The purpose of this review is to outline the benefits, risks and commercial issues of femtosecond lasers as applied to cataract surgery. RECENT FINDINGS: Cataract surgeons are adopting femtosecond technology to perform laser capsulotomy, lens fragmentation, clear cornea incisions and limbal relaxing incisions. Femtosecond lasers clearly perform these surgical steps with greater precision and reproducibility. Further benefits such as improved postoperative refractive results and reduced complication rates are being investigated. Commercial issues have invariably arisen such as cost of installation and operation, value proposition and return on investment. SUMMARY: Femtosecond cataract surgery is an evolving procedure that can potentially lead to better and safer surgical outcomes. This review presents the currently available scientific evidence and discusses some of the relevant financial issues concerning this technology.

RESUMO

PURPOSE: To present the histopathologic findings of the conjunctiva of a patient with Stevens-Johnson syndrome (SJS)-associated ocular surface neovascularization (OSN) after topical bevacizumab (TB) treatment. METHODS: A 40-year-old man with SJS and OSN received topical bevacizumab (25 mg/mL) for 12 months in 1 eye in addition to previously bilaterally administered tobramycin/dexamethasone eye drops. He subsequently underwent bilateral release of symblephara to relieve diplopia. Conjunctival samples from both eyes were obtained for histopathologic study. RESULTS: The TB-untreated conjunctiva manifested marked stromal vascularization (approximately 4-5 blood vessels per high-power field) and perivascular mononuclear inflammatory cells. The TB-treated eye manifested with markedly less stromal vascularization (approximately 1-2 vessels per high-power field) in the conjunctiva and absence of perivascular inflammatory cells. CONCLUSIONS: These histopathologic findings provide evidence that TB penetrates the ocular surface, induces regression of OSN, and possibly moderates ocular inflammation. TB may be a useful additional treatment for OSN among patients with SJS.

RESUMO

PURPOSE: To determine vitreous concentrations of triamcinolone acetonide(TA) following transseptal injection. METHODS: TA (40 mg/l ml) was administered at varying intervals prior to vitrectomy. Vitreous samples from 18 patients were obtained. TA concentrations were quantified using HPLC-MS. RESULTS: Vitreous levels of TA were detected in all samples (range 0.64-168.0 ng/ml). The interval from injection to sampling ranged from 0.5-20 days. Tmax was attained at 0.5 days. TA concentrations were negatively correlated with scleral thickness (P = 0.0184) and depot location (P = 0.0230) but not with PVD status (P = 0.9633). CONCLUSION: Significant vitreous concentrations of TA are achieved after a single transseptal injection. Scleral thickness, depot location and time influence vitreous TA levels.

RESUMO

Limbal relaxing incisions (LRI) were performed in a 35-year-old man with Graves ophthalmopathy and lower eyelid retraction. He underwent intraocular lens exchange in 1 eye and cataract surgery in the other. Despite the return of normal thyroid function, aggressive lubrication, and antiinflammatory medication, the LRIs failed to heal, leaving gaps in the limbal cornea. Limbal relaxing incisions should be avoided in Graves ophthalmopathy with lower eyelid retraction and/or exposure keratopathy.

RESUMO

PURPOSE: To evaluate the efficacy and safety of topical bevacizumab on ocular surface neovascularization among patients with Stevens-Johnson syndrome. METHODS: This was a retrospective, interventional case report. Three eyes of 2 patients were examined. Bevacizumab (25 mg/mL) eyedrops were applied 4 times daily for a period of 3 months. Main outcome measures were improvement of symptoms, visual acuity, degree of ocular surface neovascularization, corneal opacification, conjunctival injection, and occurrence of adverse events. RESULTS: Both patients completed the 3-month observation period and reported that it significantly improved ocular comfort. At the end of the study period, visual acuity improved in all 3 eyes; all eyes were observed to have decreased ocular surface neovascularization, corneal opacification, and conjunctival injection. No serious adverse events were reported. CONCLUSIONS: Topical bevacizumab is well tolerated and may be effective in improving comfort and inducing regression of ocular surface neovascularization, conjunctival injection, and corneal opacification in patients with ocular surface disease caused by Stevens-Johnson syndrome. Further controlled and long-term studies are needed to fully evaluate the long-term effects of this novel treatment.

RESUMO

An interventional case report is described of a patient with chronic postoperative endophthalmitis caused by the gram-negative aerobic rod Pseudomonas luteola. A 61-year-old developed slowly progressive blurring of vision, hypopyon, and vitritis following cataract surgery. Diagnostic vitrectomy and intraocular lens explantation were performed. The undiluted vitreous samples and explanted lens were analyzed. Aerobic cultures revealed moderate growth of P. luteola. The patient responded to intravitreal injections of piperacillin/tazobactam and oral trimethoprim/sulfamethoxasole. Best-corrected visual acuity improved from hand motions to 20/40. A repeat anterior chamber tap was negative. P. luteola may be a relatively nonvirulent cause of chronic endophthalmitis. Good visual outcomes may be obtained with appropriate therapy.

RESUMO

OBJECTIVE: To report a case of frosted-branch angiitis. METHOD: This is a case report of frosted-branch angiitis seen at the University of the Philippines-Philippine General Hospital. RESULTS: A 42 year-old male presented with progressive blurring of vision of the left eye. Indirect funduscopy showed dilated retinal veins with perivascular sheathing, giving the appearance of frosted-branches of a tree. CONCLUSION: Frosted-branch angiitis is a rare form of retinal vasculitis with various etiologies. Despite the severe retinal appearance, the prognosis is usually good, with rapid recovery of visual acuity after prompt steroid treatment.
