RESUMO

PURPOSE: To assess the utility of pig head model as an oculoplastic surgical training tool. METHODS: Fresh pig head was availed for surgical workshop for entropion correction, eyelid margin repair, and evisceration with implant for oculoplastic surgery-naïve participants. Skill improvement, surgical understanding, and performance of the participants were evaluated both subjectively and objectively by trained oculoplastic surgeons. Subjective assessment was done by a standardized questionnaire based on Likert scale shared with the participants post training. Objective evaluation was done by the faculty based on a three-point scale and a competency-based surgical assessment rubric. RESULTS: There were 18 surgery-naïve participants in the workshop which comprised ophthalmology residents and comprehensive ophthalmologists. About 88.88% of the participants were able to perform the lid margin and sub-tarsal dissection in entropion surgery. While performing lid tear repair, 94.44% were correctly able to identify the grey line and anterior and posterior lamellae. About 83.33% of the participants were able to place an implant in the scleral shell or intraconal space. About 83.33% of the participants noted that texture and tissue maneuvering were similar to the human eye while performing surgical steps. About 94.44% of the participants reported better understanding, development of skill and additional confidence after training. The median score on objective assessment was 3. The performance on real patients resulted in a median score of 4 for entropion correction. CONCLUSION: Porcine orbital dissection is an available, affordable, and useful tool for oculoplastic surgical training. Training on porcine model can improve anatomical understanding, clinical judgement, and surgical efficiency in trainees.

RESUMO

Amines, which are classified as volatile organic compounds (VOCs), serve a variety of purposes in the fields of environmental monitoring, food safety, and healthcare diagnosis. The present technique for detecting amine levels involves sophisticated setups and bulky equipment. Here. In this study, a chemoresistive gas sensor is developed that is cost-effective and easy to operate at room temperature (RT). The sensor is designed specifically for the detection of Ammonia, dimethylamine (DMA), trimethylamine (TMA), and total volatile basic nitrogen (TVB-N). Using biphenyl-reduced graphene oxide (B-rGO) composite gas sensors effectively addresses the issues of low sensitivity-selectivity and long-term instability commonly observed in conventional amine sensors. B-rGO sensor produced sensitivity of ∼3500 and selectivity above 30 for TVB-N sensing. The sensor is stable for temperature fluctuations below 50 °C and shows stable sensing response for period of over 3 months. A Chemoresistive B-rGO sensor was developed using an ultrasonic spray deposition system with optimized flow rate of 50 mL/h. Rapid evaporation of solvent using hot plate has resulted in unique morphology for B-rGO film sensors. The highest sensitivity, ∼836, is obtained for 100 ppm of ammonia with ammonia > DMA > TMA as a sensitivity order. B-rGO showed almost seven times higher amine sensitivity than rGO which highlights the importance of biphenyl in the B-rGO composite. Sensor calibration curve has been presented in the study to understand change in the sensitivity of sensor with increasing analyte gas concentration. The calibration curve has an average R-squared value of 0.98.

RESUMO

PURPOSE: To investigate the impact of surgical timing on visual acuity outcomes in retinal detachments based on the preoperative foveal status. METHODS: A retrospective multicenter cohort study was conducted. Cases were stratified into fovea-on, fovea-split, and fovea-off groups. Days to surgery was defined as the time between the preoperative examination and surgery. The main outcome measure was the final postoperative visual acuity. RESULTS: 1,675 cases were studied. More than 80% of fovea-on/fovea-split and fovea-off cases had surgery within 1 and 3 days, respectively. The mean final postoperative visual acuity did not differ significantly between the fovea-on and fovea-split groups (Snellen equivalent [SE] 20/33 ± 20/49 and 20/32 ± 20/39, P = 1.000) and did not change significantly based on days to surgery in either group. The mean final postoperative visual acuity was lowest in the fovea-off group (Snellen equivalent = 20/56 ± 20/76, P < 0.001) and was significantly lower in cases where surgery was performed after two or more days when compared with cases performed within 1 day (Snellen equivalent 20/74 ± 20/89 vs. 20/46 ± 20/63, P < 0.001). CONCLUSION: Fovea-on and fovea-split retinal detachments demonstrated comparable visual outcomes. Fovea-off RDs demonstrated worse visual outcomes, which declined further when surgery was delayed by two or more days.

RESUMO

PURPOSE OF REVIEW: To discuss the drawbacks and propose recommendations for integrating physician extenders in ophthalmologic practice. RECENT FINDINGS: In this article, the role of utilizing physician extenders in ophthalmology is discussed. A role for physician extenders has been suggested as more and more patients will require ophthalmologic care. SUMMARY: Guidance is needed on how to best integrate physician extenders into eye care. However, quality of care is of the highest importance, and unless there is reliable and consistent training of extenders, using physician extenders to administer invasive procedures (e.g., intravitreal injection) should be avoided due to safety concerns.

RESUMO

INTRODUCTION: In 2018, a unique maculopathy associated with chronic pentosan polysulfate sodium (PPS) use for the treatment of interstitial cystitis (IC) was described, where the authors detailed macular retinal pigment epithelial abnormalities in six patients. In this paper, a retrospective study of a larger patient pool at one large tertiary retina practice was undertaken to evaluate patients taking PPS and their macular findings. MATERIALS AND METHODS: A retrospective chart review was performed on all patients presenting to a single large retina practice between 2011 and 2019. Patient's macular diagnosis, findings, optical coherence tomography scans, and macular auto-fluorescent scans were assessed. This project was Institutional Review Board (IRB) approved by the St Luke's Hospital IRB board (St Louis, MO, USA). RESULTS: Fifty-five patients were identified as taking PPS for IC. Fifty-three patients were found to have a diagnosis consistent with changes attributable to known macular diseases to include macular degeneration and pattern dystrophies. Two (4%) of fifty-five patients had macular findings suggestive of PPS toxicity. The first was a 58-year-old female with subtle retinal pigment epithelium (RPE) deposits on optical coherence tomography that exhibited hyper-autofluorescence. The second was a 72-year-old female with 14 years of PPS use who exhibited RPE excrescences and parafoveal areas of atrophy. CONCLUSIONS: Pentosan polysulfate sodium may be the cause of macular findings in a small percentage of patients referred to a tertiary retina practice. Although causation of macular changes with PPS use has yet to be elucidated, clinicians should be aware of this possibility when assessing patients with atypical macular findings. Future longitudinal studies are necessary to evaluate a definitive relationship. This paper should remind all clinicians of the importance of a throughout review of the patient's medication list as novel toxicities may become apparent years after initial FDA trials. The strength of this study is the larger patient population compared to earlier studies, and the main weaknesses include the retrospective nature of the study, lack of family and genetic testing, and lack of multimodal imaging for all patients.

RESUMO

We describe the outcomes of oral mucous membrane grafting as a surgical technique for unilateral lid margin keratinization following radiotherapy. A 47-year- old woman presented with an 8-month history of a white spot in her right eye. She had a history of adenoid cystic carcinoma of the right spheno-ethmoid sinus, for which she underwent radiotherapy. Slit-lamp evaluation revealed lid margin keratinization of the right upper and lower eyelids and a keratin plaque on the corneal surface. We performed excision of the keratin plaque and lid margin keratinization, followed by oral mucous membrane grafting of the upper and lower eyelid margins. Histopathological evaluation of the excised lid margin revealed keratinized stratified squamous epithelium, consistent with lid margin keratinization. The corneal surface and lid margins showed no recurrent keratin deposition at the final follow-up, 11 months postoperatively.

RESUMO

Purpose: To determine the incidence of vitreous loss and visual outcome after a vitreous loss during cataract surgery performed by surgeons with various levels of experience in adults >40 years of age at a tertiary eye care center in North India. Methods: The study was conducted at a tertiary eye care center in North India. This was an observational, retrospective, cross-sectional study of patients who underwent cataract surgery from August 1, 2011 to July 31, 2014. All adult cataract cases who were operated on from August 1, 2011 to July 31, 2014 and who experienced vitreous loss during their surgery were included in the study. The visual outcomes of these patients who experienced vitreous loss during cataract surgery in uncomplicated cataract and were managed using standard automated vitrectomy techniques were assessed for different cataract surgical techniques (extracapsular, small-incision, and phacoemulsification) as well as at different levels of skill of the operative surgeon (consultant, short term fellow, and long-term fellow). Details of the postoperative period and best-corrected visual acuity (BCVA) were collected from patient records by the principal investigator on day 1, 1 week, 4 weeks, 6 weeks, and 3 months post cataract surgery. Results: Vitreous loss occurred in 374 out of 18,430 patients who underwent cataract surgery from August 1, 2011 to July 31, 2014. The overall incidence of vitreous loss in our study was found to be 2.03% with consultants having a rate of 1.66%, short-term fellows at 5.19%, and long-term fellows at 2.02%. Two hundred eighty-eight patients of the 374 cases followed up for 3 months at the hospital and 75.69% of these patients had a final visual acuity of ≥6/18. Conclusion: In an institute with a structured training program for residents/trainees, the vitreous loss rate is low during cataract surgery. Early intervention and proper management with the standard microsurgical technique by experienced hands can improve the final visual outcome in eyes with vitreous loss. Cystoid macular edema and corneal edema were the most common causes of poor postoperative vision.

RESUMO

We describe a rare case of a 58-year-old female with ocular surface squamous neoplasia (OSSN) in her left eye. She was treated for 12 months with topical interferon alpha-2b (IFNα-2b) eye drops and OSSN resolved completely. She presented with a whitish elevated lesion involving the cornea, limbus, and conjunctival surface after discontinuation of topical IFNα-2b. Excision biopsy along with amniotic membrane grafting was done to stabilize the ocular surface. Histopathological evaluation of the excised tissue revealed ocular surface inflammation with no evidence of malignancy.

RESUMO

PURPOSE: To compare pars plana vitrectomy (PPV) with combined PPV and scleral buckle (PPV/SB) for repair of primary rhegmatogenous retinal detachment (RRD) with associated vitreous hemorrhage (VH). DESIGN: Retrospective, observational study. PARTICIPANTS: Patients with RRD and associated VH who underwent PPV or PPV/SB from January 1, 2010, through August 31, 2020, were analyzed. METHOD: We performed a single-institution, retrospective, observational study of 224 eyes with RRD and VH at the time of detachment. We excluded eyes with <6 months of follow-up, a prior history of retinal detachment (RD) repair with vitrectomy or SB, VH that resolved before surgical intervention, and tractional or combined tractional and rhegmatogenous detachments. MAIN OUTCOME MEASURES: Single-surgery anatomic success (SSAS) at 6 months, defined as no recurrent RD requiring surgical intervention. RESULTS: Pars plana vitrectomy and PPV/SB were performed on 138 eyes (62%) and 85 eyes (38%), respectively. The mean age of the PPV and PPV/SB patients was 61.9 and 60.2 years, respectively. Single-surgery anatomic success was achieved in 107 of 138 eyes (77.5%) that underwent PPV and 78 of 85 eyes (91.7%) that underwent PPV/SB. The difference in SSAS between types of treatment was significant (P = 0.006). Mean visual acuity improvement in the PPV/SB group was 0.54 logMAR units greater than that in the PPV group (P = 0.126). The incidence of postoperative proliferative vitreoretinopathy in the PPV/SB group (11.7%) was lower than that in the PPV group (19.5%; P = 0.128). The rate of repeat PPV for non-RD reasons was similar for both the groups (P = 0.437). Final reattachment status was achieved in 137 of the 138 and 84 of the 85 eyes in the PPV and PPV/SB groups, respectively. Final visual acuity improvement was significantly better in eyes with PPV/SB than in eyes with PPV alone (logMAR 2.12 vs. 1.26, respectively; P = 0.011). CONCLUSIONS: In patients with RRD and VH, SSAS was superior in patients treated with PPV/SB compared with those treated with PPV alone. Although not significantly different, the PPV/SB group had better visual outcomes and a lower postoperative proliferative vitreoretinopathy rate.

RESUMO

BACKGROUND AND OBJECTIVE: Posterior vitreous detachment (PVD) is a separation of the posterior hyaloid from the retina that manifests as photopsias and floaters. Optical coherence tomography (OCT) has demonstrated posterior vitreous opacities (PVOs) that may correlate with Shaffer's sign, which may correlate with retinal breaks. PATIENTS AND METHODS: Patients with symptomatic PVDs were retrospectively reviewed at a single institution by a single provider. Masked qualitative review of SD-OCTs by a single reviewer determined presence of PVOs. RESULTS: Among 78 patients, PVOs were found in 32 of the patients (41%), and 19 (59%) had retinal breaks. In those without PVOs, six (13%) had a break. Sensitivity and specificity were 76.0% and 75.5%, respectively. Removing patients with vitreous hemorrhages, sensitivity, and specificity of PVOs was 82.4% and 86.4%, respectively. CONCLUSION: In symptomatic PVDs, PVOs on OCT correlated with the presence of a retinal break, especially in the absence of a vitreous hemorrhage.

RESUMO

PURPOSE: To detail the methodology for a large multicenter retrospective cohort study (RCS) of primary rhegmatogenous retinal detachment (RRD) with detailed data collection and to present overall anatomic outcomes. DESIGN: This study used an RCS method. PARTICIPANTS: All patients undergoing pars plana vitrectomy (PPV), scleral buckling (SB), and combined PPV/SB for primary RRD in 2015 from 5 large retina groups were included in the database. METHODS: To ensure validity of the cohort method, a large and detailed database was generated. Double data entry validation was conducted, and data audits were conducted. Anatomic and visual outcomes for all the cases in the dataset will be described but not compared, because the cases were not matched. In future studies, comparable cases of moderate-complexity RRD will be chosen naive to surgeon, surgery, and outcome for subgroup analysis. MAIN OUTCOME MEASURES: Precision of data entry was confirmed by inter-rater reliability (IRR). Main surgical outcome for each procedure type was single-surgery anatomic success (SSAS). RESULTS: Inter-rater reliability showed significant agreement among raters (P < 0.001). Of 2620 patients, 2335 had >90 days of follow-up. Of these, 320 eyes (13.7%) underwent SB, 1200 eyes (51.4%) underwent PPV, and 815 eyes (34.9%) underwent PPV/SB. The SSAS was 84.2% for PPV, 91.2% for SB, and 90.2% for PPV/SB. CONCLUSIONS: We compiled a large, accurately documented database of primary RRD cases repaired by PPV, SB, and PPV/SB from which cohort studies of moderately complex RRDs can be carried out. All 3 approaches had a high SSAS rate. Procedures chosen and their outcomes are described, but the broad case mix makes comparisons not possible until future cohort studies are completed.

RESUMO

PURPOSE: To evaluate the outcomes of after-hour encounters concerning patients referred by eye physicians to on-call retina services for emergent evaluation not seen in or referred by an emergency department. DESIGN: Retrospective study. PARTICIPANTS: Patients seeking treatment at 3 private practice institutions over a 2-year period between 2017 and 2018. METHODS: A retrospective chart review was conducted comprising all patients who sought treatment emergently and after clinic hours from 3 academic nonhospital-associated retina-only private practice institutions over a 2-year period. MAIN OUTCOME MEASURES: Patient presenting symptoms, diagnosis given at time of after-hours appointment, duration of symptoms, source of after-hours consultation (patient or provider), procedure performed at appointment, and appointments that led to surgery. RESULTS: Nine hundred eighty-seven charts were reviewed. Provider referrals accounted for 49.13% (n = 485) and patient-derived referrals accounted for 50% (n = 493) of appointments. New patients accounted for 27.6% (n = 146) of patient-derived and 85.2% (n = 413) of provider-derived referrals. The most common presenting symptoms were flashes and floaters (42.5%; n = 420), decrease in visual acuity (32.1%; n = 317), generalized eye pain (7.4%; n = 73), visual field disturbance (4.3%; n = 42), and postoperative ocular pain (3.4%; n = 34). An in-office procedure was performed at the time of examination in 18% of encounters (n = 178), with most of these being laser retinopexy. Surgery was performed within 24 hours in 18% (n = 180), within 48 hours in 20.6% (n = 203), within 72 hours in 21.7% (n = 214), and within 96 hours in 22.6% (n = 223) of the appointment. When combined with procedures, 36.2% (n = 358) of encounters led to urgent intervention within 24 hours. If a provider called about an existing patient, 37.5% of these appointments (n = 27) led to surgery versus 12.8% (n = 49) if an existing patient self-referred. If a provider called about a new patient, 31.7% of these appointments (n = 131) led to surgery versus 10% (n = 14) if a new patient self-referred. CONCLUSIONS: At these 3 private practice retinal specialty clinics, 41% of after-hours appointment requests resulted in an intervention within 96 hours, and 36% of these patients underwent an intervention within 24 hours.

RESUMO

PURPOSE: This study evaluates outcomes of comparable pseudophakic rhegmatogenous retinal detachment (RRD) treated with pars plana vitrectomy (PPV) or PPV with scleral buckle (PPV-SB). DESIGN: Multicenter, retrospective, interventional cohort study. PARTICIPANTS: Data were gathered from patients from multiple retina practices in the United States with RRD in 2015. METHODS: A large detailed database was generated. Pseudophakic patients with RRD managed with PPV or PPV-SB were analyzed for anatomic and visual outcomes. Eyes with proliferative vitreoretinopathy, giant retinal tears, previous invasive glaucoma surgery, and ≤90 days of follow-up were excluded from outcomes analysis. Single surgery anatomic success (SSAS) was defined as retinal attachment without ongoing tamponade and with no other RRD surgery within 90 days. MAIN OUTCOME MEASURES: Single surgery anatomic success and final Snellen visual acuity (VA). RESULTS: A total of 1158 of 2620 eyes (44%) with primary RRD were pseudophakic. A total of 1018 eyes had greater than 90 days of follow-up. Eyes with proliferative vitreoretinopathy, previous glaucoma surgery, and giant retinal tears were excluded, leaving 893 pseudophakic eyes eligible for outcome analysis. A total of 461 (52%) were right eyes. A total of 606 patients (67%) were male, with a mean age of 65±11 years. Pars plana vitrectomy and PPV-SB as the first procedure were performed on 684 eyes (77%) and 209 eyes (23%), respectively. The mean follow-up was 388±161 days, and overall SSAS was achieved in 770 eyes (86%). Single surgery anatomic success was 84% (577/684) for PPV and 92% (193/209) for PPV-SB. The difference in SSAS between types of treatment was significant (P = 0.009). In eyes with macula-on RRD, SSAS was 88% in eyes treated with PPV and 100% in eyes treated with PPV-SB (P = 0.0088). In eyes with macula-off RRD, SSAS was 81% in eyes treated with PPV and 89% in eyes treated with PPV-SB (P = 0.029). Single surgery anatomic success was greater for PPV-SB than PPV for inferior (96% vs. 82%) and superior (90% vs. 82%) detachments. Mean final VA was similar for PPV (20/47) and PPV-SB (20/46; P = 0.805). CONCLUSIONS: In pseudophakic RRDs, SSAS was better in patients treated with PPV-SB compared with PPV alone, whereas visual outcomes were similar for both groups.

RESUMO

PURPOSE: Anatomically similar rhegmatogenous retinal detachments (RRDs) can be treated with scleral buckle (SB), pars plana vitrectomy (PPV), or SB combined with PPV (PPV/SB). This study compares moderately complex phakic primary RRD treated with SB, PPV, or PPV/SB to review anatomic and visual outcomes. DESIGN: Multicenter, retrospective, interventional cohort study. PARTICIPANTS: Data were gathered on all patients from multiple retina practices in the United States with RRD in 2015 and >90 days of follow-up. The cohort of phakic patients with moderately complex RRD was analyzed. METHODS: A large and detailed database was generated. Eyes with findings that would bias toward PPV (vitreous hemorrhage, dense cataract, proliferative vitreoretinopathy, giant retinal tear, among others) were excluded. Age <40 years (bias toward SB) was excluded. Comparable cases of moderately complex RRD were then chosen naive to surgeon, surgery, and outcome for subgroup analysis. MAIN OUTCOME MEASURES: Single surgery anatomic success (SSAS), defined as retinal attachment with no other RRD surgery within 90 days, is the main outcome measure. Final visual acuity is the secondary outcome measure. Pearson's chi-square and analysis of variance were used to test treatment effect of surgery type on SSAS and vision. RESULTS: Single surgery anatomic success was noted in 155 of 169 SB cases (91.7%), 207 of 249 PPV cases (83.1%), and 271 of 297 PPV/SB cases (91.2%). Scleral buckle and PPV/SB were superior to PPV for SSAS (P = 0.0041). For macula-on or split cases, SB had significantly better visual outcomes than PPV or PPV/SB even after controlling for cataract (cases with minimal cataract at final follow-up or after cataract surgery) (P < 0.001). CONCLUSIONS: For phakic moderately complex primary RRDs in this study of PPV versus SB versus PPV/SB, SB had the best visual outcomes, and PPV had the worst SSAS outcomes.

RESUMO

Danon disease (DD) is a rare X-linked autophagic vacuolar myopathy associated with multiorgan dysfunction, including the heart, skeletal muscle, and liver. There are no specific treatments, and most male patients die from advanced heart failure during the second or third decade of life. DD is caused by mutations in the lysosomal-associated membrane protein 2 (LAMP2) gene, a key mediator of autophagy. LAMP2 has three isoforms: LAMP2A, LAMP2B, and LAMP2C. LAMP2B is the predominant isoform expressed in cardiomyocytes. This study evaluates the efficacy of human LAMP2B gene transfer using a recombinant adeno-associated virus 9 carrying human LAMP2B (AAV9.LAMP2B) in a Lamp2 knockout (KO) mouse, a DD model. AAV9.LAMP2B was intravenously injected into 2- and 6-month-old Lamp2 KO male mice to assess efficacy in adolescent and adult phenotypes. Lamp2 KO mice receiving AAV9.LAMP2B demonstrated dose-dependent restoration of human LAMP2B protein in the heart, liver, and skeletal muscle tissue. Impaired autophagic flux, evidenced by increased LC3-II, was abrogated by LAMP2B gene transfer in all tissues in both cohorts. Cardiac function was also improved, and transaminases were reduced in AAV9.LAMP2B-treated KO mice, indicating favorable effects on the heart and liver. Survival was also higher in the older cohort receiving high vector doses. No anti-LAMP2 antibodies were detected in mice that received AAV9.LAMP2B. In summary, LAMP2B gene transfer improves metabolic and physiologic function in a DD murine model, suggesting that a similar therapeutic approach may be effective for treating patients with this highly morbid disease.

RESUMO

Patients with high-risk acute promyelocytic leukemia (APL) have inferior outcomes compared with patients with low-risk APL, predominantly due to higher risk of early mortality related to hemorrhage. The majority of regimens contain prolonged maintenance, but the impact of this phase is not clear in the era of all trans retinoic acid (ATRA) and arsenic trioxide (ATO). We present a retrospective analysis of 10 patients that were treated for high risk APL based on the consolidation treatment phase of APL 0406 study without subsequent maintenance. With a median follow up of 38 months, all patients remain in remission.

RESUMO

PURPOSE: To evaluate the efficacy of unilateral tarso-frontalis silicone sling without levator extirpation or disinsertion in dampening the jaw wink in patients with congenital ptosis associated with Marcus Gunn Jaw Winking synkinesis phenomenon. METHODS: Retrospective review of medical records of all patients of congenital ptosis with moderate to severe Marcus Gunn jaw winking synkinesis who underwent unilateral tarsofrontal silicone sling surgery without extirpation of the levator muscle were retrospectively reviewed. Data were collected about the pre- and the postoperative severity of the ptosis and the amount of Marcus Gunn jaw winking excursion. RESULTS: Twenty-three patients were included in the study. Mean postoperative follow up duration was 31.2 (range 6-208) weeks. The severity of the preoperative jaw wink was mild (<2 mm excursion) in 0 patient, moderate (2-5mm) in 15 (65%) patients, and severe (>5 mm eyelid excursion) in 8 (35%) patients. Postoperatively, 20 (87%) patients had mild residual jaw wink, 3 (13%) patients had moderate jaw wink and none of the patient had severe residual jaw wink. CONCLUSION: Unilateral tarsofrontal silicone sling without disinsertion or extirpation of the levator can reduce the severity of the jaw wink excursion in patients with congenital ptosis with moderate to severe preoperative Marcus Gunn jaw winking synkinesis.

RESUMO

Dengue is a mosquito-borne flavivirus disease affecting humans. The Aedes aegypti mosquito spreads it. Ophthalmic manifestations of dengue range from subconjunctival hemorrhage to optic neuropathy. Panophthalmitis in dengue fever is a rare finding. We report a case of a 22-year-old male having dengue fever, who presented with pain, redness, swelling and loss of vision in his right eye. He was diagnosed as panophthalmitis with subretinal hemorrhage and required right eye evisceration.
