RESUMO

BACKGROUND: Uncomplicated rhegmatogenous retinal detachment (RRD) is mainly treated with vitrectomy and gas tamponade or, alternatively, scleral buckling surgery. However, gas tamponade inflates at high altitudes, causing significant complications. Silicone oil (SO) tamponade volume is unaffected by atmospheric pressure and may be used in patients who live or must undertake travel at high altitudes. PURPOSE: To determine the anatomical and functional outcomes after pars plana vitrectomy (PPV) with SO tamponade in primary uncomplicated RRD. METHODS: Twenty-eight consecutive cases of patients operated between January 2017 and December 2022 in Jules-Gonin University Eye Hospital in Lausanne were included in this retrospective study. All patients had a follow-up of at least 3 months after SO removal. RESULTS: Primary reattachment was achieved in all 28 eyes. Mean follow-up was 17.2 months (range: 3 - 51 months) after SO removal. Mean age at the time of intervention was 60 years (range: 21 - 80 years). Vision was stabilized or improved in 27 eyes (96%). One patient demonstrated a slight visual acuity decrease due to cataract formation at the last follow-up. In all patients, SO was removed 2 to 5 months after primary repair. In 14 of the 21 phakic patients, concomitant cataract surgery was performed. No surgical complications were encountered. Postoperatively, 5 (18%) patients had ocular hypertension, presumably steroid related, that was successfully controlled with topical treatment. CONCLUSION: PPV with SO injection seems to be a safe and efficient surgical approach in the treatment of primary uncomplicated RRD in patients living at high altitudes and was associated with good anatomical and functional outcome in our series. However, the need for a follow-up surgery to remove SO should be weighed in these cases.

RESUMO

We report the case of a 32-year-old male who presented with an acute myopic shift as a result of uveal effusion following a single administration of 250 mg acetazolamide. The drug was discontinued and following cycloplegia and topical steroid therapy, we observed progressive deepening of the anterior chamber, reopening of the iridocorneal angle, and complete resolution of the myopic shift after 5 days. A literature review since 1956 identified 23 cases, including ours, which developed a myopic shift after a median time of 24 h (3 - 24) following a median dose of 500 mg (125 - 1000) acetazolamide, with about a third complicated by angle closure ocular hypertension. This presumed idiosyncratic reaction can occur without prior drug exposure and independent of the phakic status. Treatment options include systematic drug withdrawal associated with cycloplegia, anti-glaucomatous agents, and/or corticosteroids. Full recovery is achieved within about 5 days (2 - 14). Given the widespread use of acetazolamide, awareness of this idiosyncratic reaction is crucial to avoid complications of acute angle-closure glaucoma.

RESUMO

Ophthalmology faces many challenges in providing effective and meaningful eye care to an ever-increasing group of people. Even health systems that have so far been able to cope with the quantitative patient increase, due to their funding and the availability of highly qualified professionals, and improvements in practice routine efficiency, will be pushed to their limits. Further pressure on care will also be caused by new active substances for the largest group of patients with AMD, the so-called dry form. Treatment availability for this so far untreated group will increase the volume of patients 2-3 times. Without the adaptation of the care structures, this quantitative and qualitative expansion in therapy will inevitably lead to an undersupply.There is increasing scientific evidence that significant efficiency gains in the care of chronic diseases can be achieved through better networking of stakeholders in the healthcare system and greater patient involvement. Digitalization can make an important contribution here. Many technological solutions have been developed in recent years and the time is now ready to exploit this potential. The exceptional setting during the SARS-CoV-2 pandemic has shown many that new technology is available safely, quickly, and effectively. The emergency has catalyzed innovation processes and shown for post-pandemic time after that we are equipped to tackle the challenges in ophthalmic healthcare - ultimately for the benefit of patients and society.

RESUMO

Retinal prostheses hold the potential for artificial vision in blind people affected by incurable diseases of the outer retinal layer. Available technologies provide only a small field of view: a significant limitation for totally blind people. To overcome this problem, we recently proposed a large and high-density photovoltaic epiretinal device, known as POLYRETINA. Here, we report the in vivo assessment of POLYRETINA. First, we characterise a model of chemically-induced blindness in Göttingen minipigs. Then, we develop and test a minimally invasive injection procedure to insert the large epiretinal implant into the eye. Last, we show that POLYRETINA restores light-evoked cortical responses in blind animals at safe irradiance levels. These results indicate that POLYRETINA holds the potential for artificial vision in totally blind patients affected by retinitis pigmentosa.

RESUMO

The Swiss Ophthalmic Image Network (SOIN) is part of the Swiss Personalized Health Network (SPHN). SOIN contains a collaborative, clinical research environment, MI Data Lab, which allows privacy-preserving, data-driven, research. Personalized care of chronic ocular disease, based on Machine Learning (ML) and medical imaging, can dramatically improve quality of life and reduce the burden on health and social care systems. MI Data Lab allows research partners to consolidate their data in a space where doctors and data scientists cooperate to design novel ML algorithms, on curated datasets. To date, we have created several algorithms to detect ocular biomarkers automatically, and applied such tools to 100k+ retinal images. MI Data Lab enables the development of predictive models, the extraction novel traits to be explored in terms of -omic associations, treatment outcome, and priors for disease progression.

RESUMO

BACKGROUND: Marfan Syndrome is an autosomal dominant disease with multiple ocular abnormalities including ectopia lentis and a high incidence of rhegmatogenous retinal detachment (RRD). The management of RRD may be challenging in cases of aphakic patients with Marfan. PURPOSE: To report on the management of four cases of simultaneous RRD and aphakia with vitrectomy, silicone oil tamponade, and retropupillary iris-claw intraocular lens (IOL) implantation in patients with Marfan that have been operated at the Jules-Gonin Eye Hospital between 2019 and 2020. HISTORY AND SIGNS: Ages at presentation were 20, 30, 32, and 31 years, respectively. All patients had a history of extraction of a dislocated lens. None of the patients had a previous posterior vitrectomy. Two patients had records of previous measurements for IOL calculation by optical biometry (IOL Master, Carl Zeiss Meditec AG, Jena, Germany) about 1 year prior to the RRD development. In two cases, measurements for IOL calculation by optical biometry were based on the contralateral eye. THERAPY AND OUTCOME: All patients underwent 23 G vitrectomy, peripheral iridotomy, and retropupillary iris-claw IOL. No intraoperative complications were encountered. All patients had silicone oil tamponade, one of which required heavy silicone oil. Silicone oil was removed 3 months following primary surgery. Minimum follow-up was 1 year. The single surgery anatomic success rate was 100%. All patients had visual acuity of at least 0.8 at the last follow-up (1.25, 1.0, 0.8, and 0.8 respectively). The targeted refractive results were accurately achieved in all four cases postoperatively. One patient presented ocular hypertension 2 weeks after surgery due to presumed steroid response and was managed conservatively. None of the patients had silicone oil migration into the anterior chamber. CONCLUSION: Retropupillary iris-claw IOL implantation in cases of RRD and aphakia creates a barrier to tamponades from the posterior segment, effectively preventing them from entering the anterior segment of the eye. Therefore, the management of aphakia and retinal detachment with simultaneous vitrectomy and a retropupillary iris-claw IOL may be a successful strategy in reducing postoperative complications in patients with Marfan syndrome.

RESUMO

PURPOSE: To report the clinical features and treatment outcomes of patients with macular hole coexistent with rhegmatogenous retinal detachment surgically treated with pars plana vitrectomy and inverted internal limiting membrane flap technique. METHODS: Eleven consecutive patients with rhegmatogenous retinal detachment and macular hole who underwent vitrectomy and internal limiting membrane peeling with the inverted flap technique between December 2017 and February 2021 were retrospectively evaluated. The main outcome measures were retinal reattachment rate, macular hole closure rate, and postoperative best-corrected visual acuity. A nonsystematic literature review was performed to compare the study outcomes with those previously reported. RESULTS: The primary retinal reattachment rate was 90% (10/11) with one surgery and 100% with 2 surgical procedures. Macular hole closure was achieved in all patients (11/11). All patients showed an improvement in visual acuity at the final postoperative visit, and the mean postoperative best-corrected visual acuity was 0.60 ± 0.32 logarithm of the minimum angle of resolution (20/80 Snellen equivalent). CONCLUSION: Vitrectomy with the inverted internal limiting membrane flap technique achieved not only favorable anatomical retinal reattachment rates but also an encouraging recovery of central macular anatomy and visual function in patients with macular hole coexistent with rhegmatogenous retinal detachment.

RESUMO

IMPORTANCE: Quantifying severity of complications in rhegmatogenous retinal detachment (RRD) surgical trials is needed. A consensus classification system will help surgeons to more effectively compare harms of different surgical techniques. OBJECTIVE: To develop a new consensus-based classification to quantify severity of complications of RRD surgery. DESIGN, SETTING, AND PARTICIPANTS: A comprehensive list of complications was developed followed by a Delphi consensus survey of international vitreoretinal surgeons. The survey was conducted in 17 countries in mainland Europe, the United Kingdom, the United States, Asia, South Africa, and Australia. Seventy vitreoretinal surgeons were invited to take part in the Delphi survey; 45 agreed to participate. Participants were selected through boards/members lists of retinal societies. Data were analyzed between April 2019 and August 2019. MAIN OUTCOMES AND MEASURES: Consensus-derived classification of complications of RRD surgery, according to their severity. RESULTS: Forty-three of 45 vitreoretinal surgeons who agreed to participate in the Delphi survey completed round 1 (96%); all but 1 (98%) completed round 2. Consensus was reached for 96% of the 84 complications assessed. Examples of complications classified as least severe (graded 1) included subconjunctival hemorrhage and chemosis while those classified as most severe included endophthalmitis and sympathetic ophthalmia (graded 9) and phthisis (graded 10). CONCLUSIONS AND RELEVANCE: We propose a new classification for quantifying severity of surgical complications based on an international consensus of vitreoretinal surgeons to quantify harm and improve the reporting of complications of RRD surgery.

RESUMO

IMPORTANCE: Knowledge on the frequency and severity of complications in surgical trials for rhegmatogenous retinal detachment (RRD) is essential to determine whether surgical procedures are developed and compared adequately, taking into account not only efficacy but also harms. OBJECTIVE: To review standards of reporting of complications in recent randomized clinical trials of RRD surgery. EVIDENCE REVIEW: This systematic review included randomized clinical trials on RRD surgery published between January 2008 and January 2021 in Embase, MEDLINE, and Web of Science Core Collection databases. Titles, abstracts, and full-text articles retrieved were reviewed for eligibility by 2 independent authors. Eligible studies were evaluated against checklist items from the Consolidated Standards of Reporting Trials Extension for Harms criteria by 2 independent authors, and discrepancies were resolved by discussion with a third author. FINDINGS: Fifty studies were included. The median number of checklist items fulfilled was 8 (range, 0-15), of a possible total of 18. Frequently reported items were discussions balanced with regard to efficacy and adverse events (42 studies [84%]) and inclusions of harm-associated timing of data collection (41 studies [82%]). The least frequently reported items were distinctions between expected and unexpected adverse events (1 study [2%]) and mentions of the use of a validated instrument to report adverse event severity (4 studies [8%]). Frequency of complications was commonly reported (29 studies [58%]) in contrast with complication severity (10 studies [20%]). CONCLUSIONS AND RELEVANCE: This review suggests that severity of complications of RRD surgery has been infrequently quantified and reported in randomized clinical trials and potentially represents an important area of improvement in future RRD surgical trials.

RESUMO

The most frequent ocular manifestation of the SARS-CoV-2 is a conjunctivitis. It is found in 1-3% of patients and has unusually a benign course. In those patients but also in patients without ocular involvement, the virus can be detected by PCR in conjunctival swabs or in the tears. Whereas the presence of the virus in the conjunctiva is proven, its transmission through the conjunctiva is still discussed. Despite the poor level of evidence, the use of protective eyewear is recommended. Ocular thromboembolic events have been described in Covid-19. They can be found in the context of the Covid-related coagulopathy. A multidisciplinary approach should be provided in these cases. In the ICU, severe ocular complications might be indirectly related to Covid-19 in ventilated patients.


La manifestation oculaire la plus fréquente du SARS-CoV-2 est une conjonctivite. Elle est retrouvée dans 1 à 3 % des cas et est généralement d'évolution bénigne. Dans le cas de conjonctivite mais aussi chez les patients asymptomatiques au niveau oculaire, le virus peut être retrouvé par PCR dans les larmes/le frottis conjonctival. Une transmission par la conjonctive reste toutefois incertaine. Par mesure de précaution, le port de lunettes de protection est recommandé. Les atteintes ophtalmologiques sévères de type thromboembolique peuvent être retrouvées dans le cadre de la coagulopathie liée au Covid-19. Dans ces cas, une prise en charge pluridisciplinaire est nécessaire. Des événements oculaires graves peuvent également être indirectement liés au Covid-19 chez les patients sous ventilation aux soins intensifs.

RESUMO

PURPOSE: We examined the postoperative visual recovery and quality of life after retinal detachment (RD) surgery. METHODS: In addition to a baseline clinical examination, patients filled out the National Eye Institute Visual Functioning Questionnaire at three time points: preoperatively and 1 and 3 months postoperatively (M1 and M3, respectively). We analyzed the composite score and short-form scores (socioemotional scale [SFSES] and visual functioning scale [SFVFS]). RESULTS: One hundred ninety-four patients were enrolled in this study; 47 (26 macula-ON RD and 21 macula-OFF RD) returned all three questionnaires. The best corrected visual acuity was Snellen equivalent 20/25, 20/25, and 20/20 at the preoperative, M1, and M3 assessment, respectively. At M3, we found a positive correlation between SFSES and best corrected visual acuity measures among macula-OFF patients (P < 0.001, R2 = 0.58). A significant correlation with the best corrected visual acuity among macula-ON patients was observed only at M3 with the SFVFS score (P < 0.001, R2 = 0.41). CONCLUSION: The quality of life differs between ON and OFF RD in regard to the composite score and especially SFSES and SFVFS. We found a transient decrease in the quality of life at M1 for macula-ON patients, whereas the quality of life improved throughout follow-up among macula-OFF patients. These data may help improve the management of patients' expectations after RD surgery.

RESUMO

PURPOSE: To quantify changes in photoreceptor density using adaptive optics fundus camera in patients after retinal detachment (RD) and to correlate them with macular involvement and best-corrected visual acuity. METHODS: At 1 and 3 months (M1 and M3) after vitrectomy, 194 patients underwent adaptive optics imagery in both eyes, at 5 locations, that we matched between time points using anatomical landmarks. Twenty-two patients (10 fovea-OFF [OFF] and 12 fovea-ON [ON]) had matched and analyzable adaptive optics images. We used analysis of variance for repeated measures. RESULTS: Best-corrected visual acuity (logarithm of the minimum angle of resolution and Snellen equivalent [SE]) was significantly different between OFF and ON RDs at baseline: 2.0 (2.3-0.95) (SE: 20/2000) versus 0 (0.1-0) (SE: 20/20); at M1: 0.35 (0.5-0.1) (SE: 20/40) versus 0.05 (0-0.1) (SE: 20/25); and at M3: 0.25 (0.3-0.1) (SE: 20/32) versus 0 (0-0) (SE: 20/20). We observed that cone density was stable in fellow eyes between M1 and M3 (P = 0.67); decreased in treated eyes than in fellow eyes (P < 0.05); and increased postoperatively in the ON group (P = 0.02) but not in the OFF group (P = 0.97). Visual acuity and RD type were independently correlated with cone density (P = 0.004, P = 0.000). CONCLUSION: Postoperative cone density was reduced in OFF RD, but also in the ON group, although the drop recovered during the 3-month follow-up. Cone density was significantly correlated with both visual acuity and type of RD at both time points.

RESUMO

PURPOSE: To evaluate the changes in choroidal thickness (CT) before and after a successful pars plana vitrectomy for rhegmatogenous retinal detachment (RD), and to compare the evolution of CT with respect to the extent of RD. METHODS: Fifty-four patients were divided into three groups: peripheral macula-on RD (>3 mm from the fovea; 14 eyes); paracentral macula-on RD (fovea-sparing; ≤3 mm from the fovea; 14 eyes); and macula-off RD (involving the fovea; 26 eyes). Choroidal thickness was measured at 1 month (M1) and 3 months (M3) postoperatively, preoperatively in macula-on RDs, with enhanced depth imaging optical coherence tomography, from the nasal side (+2.5 mm) to the temporal side (-2.5 mm) of the fovea. RESULTS: In peripheral macula-on RD, the intereye difference in CTs showed thickening throughout follow-up (subfoveally: preoperatively = 19.6% ± 43.9%, M1 = 22.9% ± 27.5%, M3 = 18.2% ± 35.6%). In paracentral macula-on RD, the intereye difference in CTs showed a thinning throughout follow-up (subfoveally: preoperatively = -7.8% ± 21.9%, M1 =-5.5% ± 26.1%, M3 = -9.3% ± 19.4%), as well as in the macula-off RD (subfoveally: M1 = -14.1% ± 18.7%, M3 = -9.9% ± 15%). CONCLUSION: The extent of RD was related to the evolution of the CT before and after surgery. Further studies are necessary to clarify the relationship between the changes in CT and the effects of circulatory alterations, vitrectomy, and RD.

RESUMO

PURPOSE: To describe a case of acute postoperative bacterial endophthalmitis because of Capnocytophaga canimorsus after cataract surgery, with probable contamination through salivary droplets of dog two days after the procedure. METHODS: An 83-year-old woman who underwent uncomplicated cataract extraction with intraocular lens implantation, presented 12 days later with acute pain, redness, and vision loss in her left eye. Visual acuity was hand motion and clinical findings suggested the diagnosis of acute postoperative endophthalmitis. The patient underwent diagnostic vitrectomy, intravitreal ceftazidime/vancomycin injection and received oral moxifloxacin (400 mg/day). Two days later, she underwent complete pars-plana vitrectomy because of the absence of clinical improvement. Vitreous samples showed gram-negative bacterium on direct examination but cultures remained sterile, which prompted the realization of a broad-range bacterial polymerase chain reaction analysis. RESULTS: Polymerase chain reaction on the vitreous sample detected C. canimorsus, a fastidious gram-negative bacterium of the oral canine flora. When asked for recent contact with dogs, the patient reported having proceeded to an intensive tooth care session for her dog at postoperative Day 2. Intravenous ceftriaxone (2 g/day) was added to the treatment. Anterior and posterior segment inflammation slowly resolved, and final visual acuity was 20/160. CONCLUSION: Although very rare, this complication suggests that patients undergoing ocular surgery should avoid contact with salivary secretions of pets during the early postoperative period. Diagnostic broad-range bacterial polymerase chain reaction is useful to detect unconventional or slow-growing agents in vitreous samples.

RESUMO

Technological advances in ophthalmology are becoming more and more important. New imaging instruments and software analysis allow ultra-wide field visualization of the retina non-invasively. This creates important clinical advantages for an aging population affected by chronic pathologies such as cataract, age related macular degeneration, and diabetic retinopathy. In particular, it will be possible to organize screening programs and an individualized approach and follow up of the patients. While new retinal implants are under development a new drug is now available for the treatment of corneal scars.


La technologie devient de plus en plus présente dans l'ophtalmologie. Les nouvelles modalités d'imagerie ainsi que les analyses automatisées permettent une visualisation de la rétine à haute résolution et à grand champ de façon non invasive. Les avantages du point de vue clinique pour la population qui vieillit et qui présente des pathologies chroniques (cataracte, dégénérescence maculaire liée à l'âge, rétinopathie diabétique) sont immédiats : organisation de dépistage et prise en charge individualisée des patients. Les développements des implants rétiniens progressent et un nouveau traitement pour les cicatrices cornéennes est désormais disponible.
