Efficacy and safety of the implantation of a single-piece angulated foldable IOL in the sulcus.

PURPOSE: To study the visual results and tolerance of a Zeiss CT Lucia 601P intraocular lens (IOL) implanted in the sulcus after complicated cataract surgery or during IOL exchange for clouded IOL. METHODS: In total, 64 patients who underwent sulcus implantation were recalled to the hospital to undergo subjective and objective refraction, best corrected visual acuity measurement, tonometry, optical coherence tomography, laser flare photometry, biometry, and wavefront aberrometry. RESULTS: In spite of a large variation in preoperative refraction, the target refraction was obtained within 1.5 diopters in approximately 97% of patients and within 0.5 diopter in 53% of patients. Average BCVA was high (Snellen 0.86) and related to concomitant (mostly retinal) pathologies in eyes with poorer visual performance. Wavefront aberrometry showed no evidence of IOL tilting or decentration after long-term implantation in the sulcus. Tonometry was not different from the fellow eye of the patient (p > 0.5). In 53 patients with bilateral pseudophakia, the laser flare photometry was not significantly different from the fellow eye (p < 0.05). CONCLUSION: This study demonstrates that this single-piece angulated foldable acrylic IOL can be considered for implantation in the sulcus. The visual results are favorable, and the IOL can be well-positioned and tolerated in the sulcus. Moreover, there were no safety issues found since there was no evidence of elevated IOP or chronic uveitis.

Patient satisfaction after EDOF intraocular lens implantation in vitrectomized eyes.

PURPOSE: To report patient satisfaction after unilateral/bilateral extended depth-of-focus (EDOF) intraocular lens (IOL) implantation in a young population after vitrectomy. METHODS: Patients that underwent phaco-vitrectomy or phaco following vitrectomy with an AT LARA EDOF IOL, aged between 18 and 75 years, were asked to fill out a questionnaire to assess overall visual quality, near vision quality, and visual disturbances. The questionnaire was based on the Catquest, NAVQ, and APPLES questionnaires. RESULTS: A total of 89 participants (average age 56.7 years) filled out the questionnaire of which 53.9% received a unilateral EDOF IOL. The most common indications for vitrectomy were retinal detachments (38.2%), floaters (36.0%), and epiretinal membranes (16.9%). The Catquest and NAVQ score respectively showed a good overall satisfaction (3.44/4.0), a good intermediate vision (3.55/4.0), and an average near vision (2.75/4.0). The APPLES score showed acceptable visual disturbances. There were no differences between the unilateral and bilateral group, except for a higher spectacle dependency in the unilateral group (40% vs. 10.6%). Participants that underwent vitrectomy in case of floaters reported lower satisfaction rates. Other variables, like the pre-operative refraction, had no impact on both satisfaction and visual disturbances. CONCLUSION: Both unilateral and bilateral implantation of the AT LARA EDOF IOL showed a high satisfaction with no differences between both groups, except for a lower spectacle use in the latter. Hence, The AT LARA seems to be a possible choice in patients undergoing vitrectomy at a younger age, even for unilateral use.

Effectiveness of immediate vitrectomy and intravitreal antibiotics for post-injection endophthalmitis.

PURPOSE: To show that an immediate vitrectomy with an intravitreal injection of antibiotics can be an effective approach for the treatment of acute endophthalmitis following intravitreal injections. METHODS: We reviewed all cases of clinical endophthalmitis caused by an intravitreal injection that were treated in our department between March 2012 and November 2019. Only patients that underwent a vitrectomy within 6 h after presentation to the clinic and with a documented visual acuity shortly before the causative event were included. Baseline best-corrected visual acuity (BCVA) before the causative event was compared to BCVA measured within a follow-up period of 8 months (up to 14 months). RESULTS: In total, 30 eyes of 30 patients were included. The BCVA before the intraocular infection was a mean value of 0.55 logMAR, and the BCVA on the day of the endophthalmitis decreased significantly to 1.66 logMAR. Within 2 months following the pars plana vitrectomy (PPV), the mean BCVA improved to 0.83 logMAR. Eight months following PPV (mean value, 8.20 months; SD, 3.59 months), the mean BCVA was 0.63 logMAR. In the last follow-up interval most of the eyes recovered, and the BCVA did not differ significantly from baseline. Two eyes underwent further pars plana surgery during the follow-up period. No enucleation was required. CONCLUSION: In this study, we have shown that an immediate vitrectomy with subsequent intravitreal injection of antibiotics is an effective option for treating post-injection endophthalmitis and frequently results in recovery of vision; thus, it should be performed as early as possible, where available.

A Comparative Study of 23-Gauge and 27-Gauge Vitrectomy for Puckers or Floaters, Including Evaluation of the Effect of Combined Phaco-Vitrectomy Surgery on Postoperative Outcome.

INTRODUCTION: A single-center, prospective randomized comparison of postoperative recovery between 23-gauge and 27-gauge surgical approaches in vitrectomy was performed. METHODS: A single-center, prospective randomized comparison of postoperative recovery between 23-gauge and 27-gauge surgical approaches to evaluate efficiencies and postoperative outcomes of the two surgical gauges. Eighty patients who were scheduled to undergo pars plana vitrectomy (PPV) for floaters or macular surgery were treated with either 27-gauge or 23-gauge techniques and assessed for efficiency of the procedures as well as a variety of postop indicators of pain and inflammation. RESULTS: 27-Gauge vitrectomy took 90 s more time compared to 23-gauge surgery. Wound closure was significantly easier in 27-gauge than 23-gauge. Less postoperative eye reddishness was seen in 27-gauge compared to 23-gauge. A trend towards less inflammation was seen in 27-gauge. CONCLUSION: Overall, the trial showed that 27-gauge has the better postoperative outcome compared to 23-gauge PPV. Combining vitrectomy with phaco-surgery did not influence the study outcome parameters.

ASSESSMENT OF ANATOMICAL AND FUNCTIONAL OUTCOMES WITH OCRIPLASMIN TREATMENT IN PATIENTS WITH VITREOMACULAR TRACTION WITH OR WITHOUT MACULAR HOLES: Results of OVIID-1 Trial.

PURPOSE: To evaluate the anatomical and functional outcomes with ocriplasmin in patients with vitreomacular traction (VMT) with or without macular hole (MH). METHODS: In a Phase 4, multicenter, single-arm, open-label study, eligible patients (VMT with focal adhesion, without epiretinal membrane, and with MH ≤400 µm [if present]) received a single intravitreal injection of ocriplasmin. Nonsurgical resolution of VMT (Day 28 [primary endpoint]), best-corrected visual acuity, MH closure, vitrectomy rate, and safety were assessed through Day 180. RESULTS: Overall, 466 patients were included in the full analysis set, of whom 47.4% had VMT resolution by Day 28; resolution rates in patients with VMT without MH, VMT with MH ≤250 µm, and VMT with MH >250 to ≤400 µm were 43.4%, 68.6%, and 62.7%, respectively. Macular hole closure was higher in eyes with VMT and MH ≤250 µm (57.1%) than in eyes with VMT and MH >250 to ≤400 µm (27.5%) at Day 28. Overall, 30.8% of patients with VMT resolution gained ≥10 letters in best-corrected visual acuity at Day 180. Adverse events were consistent with the known safety profile of ocriplasmin. CONCLUSION: Ocriplasmin is effective for resolution of VMT without or with MH (≤400 µm); treatment outcomes can be optimized with patient selection.

The role of the vitreous body in effective IOL positioning.

PURPOSE: To compare the effective lens position (ELP) after phaco surgery alone and after combined phacovitrectomy surgery. METHODS: Twenty patients who were scheduled for elective surgery in both eyes were included. In one eye, phacovitrectomy surgery was performed (without any tamponade), and in the fellow eye, only phaco surgery was performed using the same IOL type. Pre- and postoperative biometric measurements were performed using laser interference biometry. The postoperative anterior chamber depth (ACD) was measured to determine the ELP. The primary outcome measure was the difference in the postoperative ACD between both eyes. RESULTS: The postoperative ACD following phacovitrectomy showed a statistically significant increase compared with that following phaco surgery alone, indicating a more posterior position of the IOL. CONCLUSIONS: An adjusted ELP parameter to optimize IOL calculation may be useful in eyes undergoing combined phacovitrectomy sugergy.

Retinal Toxicity of Medical Devices Used during Vitreoretinal Surgery: A Critical Overview.

Retinal toxicity/biocompatibility of medical devices in direct contact with the retina is an important subject for clinicians and scientists. As these effects are not very frequent, there is also a relative lack of information for many clinicians. The past has taught us multiple times that there is a significant safety problem associated with severe loss of vision in affected patients. In this review, we want to classify medical products that are used in the back of the eye, describe recent examples of toxicity, critically reflect on the regulations that exist and suggest improvements that can be done to ensure patient safety without hindering innovation. METHODS: Critical review of the recent papers and personal experience of the authors in this issue. Medical devices used in the back of the eye and recent examples of toxicity are described, regulations that exist are critically reflected and improvements suggested that can ensure patient safety without hindering innovation. RESULTS: There is clear evidence of toxicity after intraocular surgery in any category. Some cytotoxic indirect methods have failed in detecting this toxicity. Some ISO rules do not seem appropriate. Postmarketing safety is missing. There is little data on this issue. CONCLUSIONS: The absence of a clear regulation of the production, purification and evaluation of the toxic effects of the medical devices supposes the possibility that products are not sufficiently safe to obtain the CE mark.

Prevalencia de alteraciones en la interfase vitreoretiniana detectadas mediante tomografía de coherencia óptica de dominio espectral.

Objetivo: El objetivo principal del presente estudio consistió en determinar la prevalencia de los cambios en la interfase vitreomacular (IVM) mediante tomografía de coherencia óptica (OCT) en la población general. En segundo lugar, se describieron otros cambios de la OCT. Métodos: Las anomalías en la IVM se diagnosticaron mediante OCT y se distribuyeron de acuerdo con la clasificación del grupo International Vitreomacular Traction Study (estudio internacional de tracción vitreomacular, IVTS, por sus siglas en inglés) y se dividieron en 3 grados según John et al. [Retina 2014;34:442-446]. Resultados: La prevalencia calculada de anomalías vitreomaculares en la población belga de ≥50 años fue del 1,17% [intervalo de confianza (IC 0,38-3,62)] en el caso de tracción vitreomacular (TVM) focal de grado 1; del 0,39% (IC 0,05-2,76) en el caso de TVM focal de grado 2; del 8,17% (IC 5,33-12,53) en el caso de adhesión vitreomacular focal; y del 17,9% (IC 13,41-23,9) en el caso de adhesión vitreomacular difusa. Conclusiones: Se presentó la prevalencia de anomalías vitreomaculares en un estudio de cohortes belga. Estos resultados concuerdan en gran medida con los datos presentados previamente sobre la prevalencia de la TVM. Un conocimiento correcto sobre la epidemiología de las alteraciones en la IVM y un diagnóstico temprano permitirán una intervención satisfactoria.

A retrospective cohort study in patients with tractional diseases of the vitreomacular interface (ReCoVit).

PURPOSE: To assess how vitreomacular adhesion (VMA), vitreomacular traction (VMT), and macular holes (MH) evolve, and to assess visual acuity outcomes associated with different management strategies for each subgroup. METHODS: Retrospective, single-center, observational study of 400 patients (556 eyes) who presented with optical coherence tomography (OCT) findings related to tractional diseases of the vitreomacular interface (187 with bilateral disease). The outcomes measured include prevalence of symptoms, rates of disease stabilization, spontaneous resolution, and disease progression necessitating surgical intervention. Size of VMA/VMT was not measured. RESULTS: Vision loss and metamorphopsia were the leading causes for referral. Patients were followed for a mean of 10.9 months (median 6.9 months). Spontaneous resolution occurred in 22.7 % (46/203) of eyes with VMT and in 7.3 % (9/124) of eyes with VMA (P < .001). In the former group, 34.1 % (14 eyes) showed improved visual acuity (P = .001). During follow-up, 11.3 % (14/124) of eyes with VMA showed disease progression; six (4.8 %) developed a macular hole. Eleven of the 203 eyes with VMT (5.4 %) developed a macular hole; 52 of 203 eyes with VMT (25.6 %) had disease progression that resulted in patients opting for pars plana vitrectomy (PPV). Of the eyes with VMA, 4.8 % (6/124) had disease progression resulting in patients opting for PPV. CONCLUSIONS: Better visual acuity outcomes were found in eyes with spontaneous resolution compared to the other groups. Spontaneous resolution of VMT and VMA was rare, whereas disease progression resulting in PPV was more common.

Prevalence of Vitreoretinal Interface Abnormalities as Detected by Spectral-Domain Optical Coherence Tomography.

PURPOSE: The primary objective of this study was to determine the prevalence of vitreomacular interface (VMI) changes on optical coherence tomography (OCT) in the general population. Second, other OCT changes were described. METHODS: Abnormalities in the VMI were diagnosed by OCT scan and graded according to the International Vitreomacular Traction Study (IVTS) Group classification and subdivided into 3 grades according to John et al. [Retina 2014;34:442-446]. RESULTS: The estimated prevalence of vitreomacular abnormalities within a Belgian population aged ≥50 years was 1.17% [confidence interval (CI 0.38-3.62)] for focal vitreomacular traction (VMT) grade 1; 0.39% (CI 0.05-2.76) for focal VMT grade 2; 8.17% (CI 5.33-12.53) for focal vitreomacular adhesion, and 17.9% (CI 13.41-23.9) for broad vitreomacular adhesion. CONCLUSION: The prevalence of vitreomacular abnormalities within a Belgian study cohort was reported. These results closely match previously reported data on the prevalence of VMT. Correct knowledge of the epidemiology of VMI disorders and early diagnosis will enable adequate intervention.

Enzymatic vitreolysis with ocriplasmin for vitreomacular traction and macular holes.

BACKGROUND: Vitreomacular adhesion can lead to pathologic traction and macular hole. The standard treatment for severe, symptomatic vitreomacular adhesion is vitrectomy. Ocriplasmin is a recombinant protease with activity against fibronectin and laminin, components of the vitreoretinal interface. METHODS: We conducted two multicenter, randomized, double-blind, phase 3 clinical trials to compare a single intravitreal injection of ocriplasmin (125 µg) with a placebo injection in patients with symptomatic vitreomacular adhesion. The primary end point was resolution of vitreomacular adhesion at day 28. Secondary end points were total posterior vitreous detachment and nonsurgical closure of a macular hole at 28 days, avoidance of vitrectomy, and change in best-corrected visual acuity. RESULTS: Overall, 652 eyes were treated: 464 with ocriplasmin and 188 with placebo. Vitreomacular adhesion resolved in 26.5% of ocriplasmin-injected eyes and in 10.1% of placebo-injected eyes (P<0.001). Total posterior vitreous detachment was more prevalent among the eyes treated with ocriplasmin than among those injected with placebo (13.4% vs. 3.7%, P<0.001). Nonsurgical closure of macular holes was achieved in 40.6% of ocriplasmin-injected eyes, as compared with 10.6% of placebo-injected eyes (P<0.001). The best-corrected visual acuity was more likely to improve by a gain of at least three lines on the eye chart with ocriplasmin than with placebo. Ocular adverse events (e.g., vitreous floaters, photopsia, or injection-related eye pain--all self-reported--or conjunctival hemorrhage) occurred in 68.4% of ocriplasmin-injected eyes and in 53.5% of placebo-injected eyes (P<0.001), and the incidence of serious ocular adverse events was similar in the two groups (P=0.26). CONCLUSIONS: Intravitreal injection of the vitreolytic agent ocriplasmin resolved vitreomacular traction and closed macular holes in significantly more patients than did injection of placebo and was associated with a higher incidence of ocular adverse events, which were mainly transient.

Efficacy of intravitreal ocriplasmin for treatment of vitreomacular adhesion: subgroup analyses from two randomized trials.

PURPOSE: To evaluate the efficacy of a single intravitreal injection of ocriplasmin 125 µg across relevant subpopulations of patients with symptomatic vitreomacular adhesion (VMA)/vitreomacular traction (VMT), including when associated with macular hole. DESIGN: Two multicenter, randomized, placebo-controlled, double-masked, 6-month studies. PARTICIPANTS: A total of 652 randomized patients (464 receiving ocriplasmin; 188 receiving placebo). METHODS: A single intravitreal injection of ocriplasmin 125 µg or placebo in the study eye. MAIN OUTCOME MEASURES: Prespecified subgroup analyses were conducted to evaluate the effects on the proportion of patients with nonsurgical resolution of focal VMA at day 28, nonsurgical full-thickness macular hole (FTMH) closure at month 6, and categoric improvement in best-corrected visual acuity (BCVA) at month 6. RESULTS: Resolution of VMA at day 28 was achieved more often in younger patients (<65 years), eyes without epiretinal membrane, eyes with FTMH, phakic eyes, and eyes with a focal VMA ≤ 1500 µm. Eyes with FTMH width ≤ 250 µm were more likely to achieve nonsurgical FTMH closure. Categoric ≥ 2-line and ≥ 3-line improvement in BCVA occurred more often in younger patients (<65 years) and in patients with a lower baseline BCVA (<65 letters). Treatment differences in favor of ocriplasmin were generally observed across each subgroup of subpopulations studied. CONCLUSIONS: Subgroup analyses confirmed the positive effect of ocriplasmin across relevant subpopulations.

COHORT SAFETY AND EFFICACY STUDY OF SILURON2000 EMULSIFICATION-RESISTANT SILICONE OIL AND F4H5 IN THE TREATMENT OF FULL-THICKNESS MACULAR HOLE.

PURPOSE: To evaluate safety and efficacy of using Siluron2000 silicone oil in the treatment of full-thickness macular hole by comparing its propensity to emulsify with emulsification of the "gold standard" Siluron5000, and to assess safety and efficacy of F4H5 (perfluorobutylpentane) in removing emulsified oil droplets from the eye. METHODS: A single-center, randomized controlled parallel group trial in 72 patients undergoing vitrectomy for treatment of full-thickness macular hole. The study comprises four treatment groups. First, the total patient group was divided into 2 study arms of 36 patients each, receiving either Siluron2000 or Siluron5000 after vitrectomy with a 3-month follow-up after vitrectomy. Second, F4H5 was used during oil removal in half of the patients in each study arm (18 patients within each study arm) with follow-up at 6 weeks after oil removal. Oil droplets were counted within the removed oil; residual emulsification bubbles were quantified using ultrasound imaging. RESULTS: Safety and efficacy of the oils were comparable. Injection and removal time of Siluron2000 oil was significantly less than that of Siluron5000 oil. Patients treated with F4H5 had borderline significantly less emulsification droplets than those not treated with F4H5. CONCLUSION: Siluron2000 silicone oil seems to be equally safe and effective as Siluron5000 oil but allows for better handling with the potential of reducing procedure time. The application of F4H5 seems to be safe and effective in reducing residual emulsification.

Improved efficacy of ocriplasmin for vitreomacular traction release and transient changes in optic disk morphology.

PURPOSE: To determine the efficacy and safety of ocriplasmin for vitreomacular traction (VMT) resolution and to study changes in optic disk and peripapillary region. METHODS: Retrospective, single-center, observational case series. In 38 eyes with VMT (10 with concomitant full-thickness macular hole), determined by optical coherence tomography, a single intravitreal injection of ocriplasmin was administered. Baseline ocular characteristics included the presence/absence of epiretinal membrane, lens status, and vitreomacular adhesion size. Spectral domain optical coherence tomography and Heidelberg retinal tomography were performed at baseline and follow-up visits. RESULTS: A total of 71.1% of eyes treated with ocriplasmin had VMT resolution, improving to 83.9% after applying MIVI-TRUST selection criteria. A total of 90% of eyes with full-thickness macular hole showed VMT resolution, with 40% of those achieving full-thickness macular hole closure. Subretinal fluid in the macular region was observed in 36.8% of eyes 1 day after injection, and all cleared spontaneously by Day 42. A significant difference was observed in cup/disk area ratio between patients who achieved VMT resolution and patients who did not. CONCLUSION: Careful patient selection improves ocriplasmin efficacy. Transient optic disk morphology changes such as decreased cup/disk area ratio may occur in patients without VMT resolution.

Association between anatomical resolution and functional outcomes in the mivi-trust studies using ocriplasmin to treat symptomatic vitreomacular adhesion/vitreomacular traction, including when associated with macular hole.

PURPOSE: To evaluate visual function in patients with symptomatic vitreomacular adhesion (VMA)/vitreomacular traction including when associated with macular hole after ocriplasmin treatment, and the association between resolution of the underlying condition and improvement in visual function. METHODS: Six hundred and fifty-two patients from 2 Phase 3 trials received a single intravitreal injection of ocriplasmin 125 µg (n = 464) or placebo (n = 188). Mean and categorical changes from baseline in best-corrected visual acuity and 25-item Visual Function Questionnaire scores were used to evaluate visual function. Subgroups with VMA resolution and full-thickness macular hole closure were compared. RESULTS: Overall, 42% of patients who achieved VMA resolution at Day 28 had a ≥2-line improvement in best-corrected visual acuity at Month 6, and 20% had a ≥3-line improvement. Likewise, 69% of patients with nonsurgical full-thickness macular hole closure at Day 28 had a ≥2-line improvement at Month 6, and 48% had a ≥3-line best-corrected visual acuity improvement. Mean improvements in 25-item Visual Function Questionnaire scores were associated with achieving VMA resolution and nonsurgical full-thickness macular hole closure. CONCLUSION: In patients with symptomatic VMA/vitreomacular traction, VMA resolution and nonsurgical full-thickness macular hole closure were each associated with improvements in visual function. Resolving the underlying anatomical condition in symptomatic VMA/vitreomacular traction will increase the probability of achieving a clinically meaningful improvement in visual function.

Efficacy and safety evaluation of Monoblue Dual View and Monoblue ILM View vital stains during vitrectomy surgery.

PURPOSE: To compare the staining properties of Monoblue inner limiting membrane (ILM) View and Monoblue DUAL View (study products) vital stains during vitrectomy surgery to those of ILM Blue or Membrane Blue Dual (control products). METHODS: In this study, 105 patients were included in the Ophthalmic Clinic of the University Hospitals Leuven from September 2021 to April 2022. For prospective data collection in this study, patients were randomized between a control group (ILM Blue or Membrane Blue Dual, manufactured and commercialized by DORC®) and a study group (Monoblue ILM View or Monoblue DUAL View, manufactured and commercialized by Arcadophta®-BVI®). For retrospective data collection, patients were divided into similar surgery groups. Efficacy was analyzed using a binary subjective evaluation of the visualization of stained membranes during vitrectomy. The rate and severity of potential adverse events related to the study products were tracked, allowing both treatment groups to be compared with the corresponding control groups (ILM Blue and Membrane Blue Dual). RESULTS: Based on the results and findings, none of the comparisons (primary outcomes) were statistically significant, showing similar efficacy of the dyes used. The study products were found to be safe in this study since no serious adverse events were reported. CONCLUSIONS: The present findings indicate that the Monoblue ILM View and Monoblue DUAL View dyes can safely be used during vitrectomy to stain the ILM and/or epiretinal membrane (ERM) when removal is needed.

The International Vitreomacular Traction Study Group classification of vitreomacular adhesion, traction, and macular hole.

OBJECTIVE: The International Vitreomacular Traction Study (IVTS) Group was convened to develop an optical coherence tomography (OCT)-based anatomic classification system for diseases of the vitreomacular interface (VMI). DESIGN: The IVTS applied their clinical experience, after reviewing the relevant literature, to support the development of a strictly anatomic OCT-based classification system. PARTICIPANTS: A panel of vitreoretinal disease experts was the foundation of the International Classification System. METHODS: Before the meeting, panel participants were asked to review 11 articles and to complete 3 questionnaires. The articles were preselected based on searches for comprehensive reviews covering diseases of the VMI. Responses to questionnaires and the group's opinions on definitions specified in the literature were used to guide the discussion. MAIN OUTCOME MEASURES: Optical coherence tomography-based anatomic definitions and classification of vitreomacular adhesion, vitreomacular traction (VMT), and macular hole. RESULTS: Vitreomacular adhesion is defined as perifoveal vitreous separation with remaining vitreomacular attachment and unperturbed foveal morphologic features. It is an OCT finding that is almost always the result of normal vitreous aging, which may lead to pathologic conditions. Vitreomacular traction is characterized by anomalous posterior vitreous detachment accompanied by anatomic distortion of the fovea, which may include pseudocysts, macular schisis, cystoid macular edema, and subretinal fluid. Vitreomacular traction can be subclassified by the diameter of vitreous attachment to the macular surface as measured by OCT, with attachment of 1500 µm or less defined as focal and attachment of more than 1500 µm as broad. When associated with other macular disease, VMT is classified as concurrent. Full-thickness macular hole (FTMH) is defined as a foveal lesion with interruption of all retinal layers from the internal limiting membrane to the retinal pigment epithelium. Full-thickness macular hole is primary if caused by vitreous traction or secondary if directly the result of pathologic characteristics other than VMT. Full-thickness macular hole is subclassified by size of the hole as determined by OCT and the presence or absence of VMT. CONCLUSIONS: This classification system will support systematic diagnosis and management by creating a clinically applicable system that is predictive of therapeutic outcomes and is useful for the execution and analysis of clinical studies.

Oct-based interpretation of the vitreomacular interface and indications for pharmacologic vitreolysis.

PURPOSE: To review the role of optical coherence tomography (OCT) in diagnosis and management of vitreomacular disease and the impact of OCT on potential uses of ocriplasmin, a new pharmacologic vitreolysis agent recently approved by the U.S. Food and Drug Administration for the treatment of symptomatic vitreomacular adhesion. METHODS: Analysis of current literature regarding OCT in diagnosis and management of vitreomacular interface disease. RESULTS: Posterior vitreous detachment is typically a nonpathologic age-related event. Anomalous posterior vitreous detachment emerges when the vitreous cortex fails to cleanly detach from the macula, optic nerve, or other adherent sites. Focal vitreomacular adhesion is a nonpathologic anatomical designation associated with perifoveal posterior vitreous detachment but normal retinal morphology on OCT. Vitreomacular traction is a pathologic consequence of persistent vitreous attachment with structural disturbance of the macular retina visible on OCT. Full-thickness macular holes are foveal defects continuous through all retinal layers to the retinal pigment epithelium. Vitreomacular traction and macular hole with focal vitreomacular adhesion are indications for pharmacologic vitreolysis. CONCLUSION: Noninvasive high-resolution OCT imaging has transformed the understanding of vitreomacular interface disease. Careful evaluation of the vitreomacular interface with OCT has increased in importance with the introduction of ocriplasmin for vitreomacular adhesion associated with symptomatic anatomical retinal changes.

Outcomes of different management options for malignant glaucoma: a retrospective study.

BACKGROUND: To assess the outcomes of the various medical and surgical treatment options for malignant glaucoma. METHODS: Design Retrospective, comparative case series. Participants Twenty-four eyes of 21 patients with malignant glaucoma. Intervention Nine eyes were treated medically. Twenty-one eyes underwent surgery, 15 of which had the full vitrectomy-(phaco)-iridectomy-zonulectomy procedure. Main outcome measures Intraocular pressure (IOP), best-corrected visual acuity (BCVA) and number of glaucoma medications were measured. RESULTS: The relapse rate was 100% after medical therapy, 75% after a Yag laser capsulotomy and a hyaloidotomy, 75% after a conventional vitrectomy and 66% after an anterior vitrectomy in combination with an iridectomy-zonulectomy. All patients who underwent a full vitrectomy combined with an iridectomy and a zonulectomy (and phacoemulsification if phakic) had postoperative relief of malignant glaucoma without relapse within the follow-up period. After this vitrectomy-tunnel technique, the IOP ranged from 10 to 22 mmHg (mean 16 mmHg) after a mean follow-up of 61 days. Mean BCVA improved by 5 Early Treatment Diabetic Retinopathy Study (ETDRS) lines, and mean number of glaucoma medications decreased from two to one. CONCLUSION: Complete vitrectomy combined with iridectomy and zonulectomy (and phacoemulsification, if applicable) most successfully managed aqueous misdirection syndrome in our retrospective case series.
