CANADIAN JOURNAL OF OPHTHALMOLOGY 2024; 59:102-108. [PMID: 36610705 DOI: 10.1016/j.jcjo.2022.12.003] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 08/05/2022] [Revised: 11/11/2022] [Accepted: 12/13/2022] [Indexed: 01/05/2023]
Abstract
OBJECTIVE To evaluate the effect of socioeconomic and demographic factors on outcomes in rhegmatogenous retinal detachments (RRDs). DESIGN Retrospective cohort study. METHODS A total of 71 white and 124 black and/or Hispanic patients who had surgical repair of RRDs between October 2013 and September 2021 at a single-centre safety net hospital. Main outcomes were single surgery success rates (SSSR) and postoperative visual acuity at 6-month and final follow-up. RESULTS Black and (or) Hispanic patients were significantly younger (black and [or] Hispanic, 50.7 years vs white, 57.6 years; p = 0.003), had lower mean household incomes (black and [or] Hispanic, $80,932 vs white, $92,911; p = 0.007), were more likely to have more than 1 retinal break (black and [or] Hispanic, 65% vs white, 49%; p = 0.04), and had higher rates of proliferative vitreoretinopathy (PVR) at presentation (black and [or] Hispanic, 35% vs white, 18%; p = 0.02). SSSR was similar (black and [or] Hispanic, 73.4% vs white, 73.2%; p = 0.98), but black and (or) Hispanic patients had worse visual acuity postoperatively (black and [or] Hispanic, 20/63 vs white, 20/40 at final follow-up; p = 0.03). While race was linked to visual outcome in univariate testing; multivariate analysis revealed only macula status (p = 0.007 at 6 months; p = 0.01 at final follow-up), presence of PVR (p < 0.001 at both time points), and SSSR (p = 0.003 at final follow-up) as predictors of worse visual outcomes. CONCLUSIONS Preoperative factors such as higher rates of PVR may contribute to worse vision outcomes in black and (or) Hispanic patients undergoing surgical repair for RRD.

Abstract
Background The fellow eye of a retinal detachment is at risk of developing a retinal detachment and other visually debilitating disease. Aim To investigate the rate of bilaterality of retinal detachment (RD), the presenting visual acuity (VA), and the presence of ocular morbidity in the fellow eye of patients with RD. Patients and Methods A multicenter, prospective, cross-sectional study examining the fellow eye of consecutive patients who were diagnosed with different types of RD. The patients were seen within one year and examined in four Nigerian eye hospitals and clinics. Demographics, VA, and clinical findings at the presentation were reported on examination of the fellow eyes. Results Twenty-seven (11.4%) out of 237 patients (264 eyes) had an RD in the fellow eye. The mean age of all study patients was 46.2 ± 16.8 years, M/F: 161 (67.9%)/76 (32.1%). The rates of bilaterality for rhegmatogenous, exudative, and tractional RDs were 4.2%, 11.1%, and 31.1%, respectively. Diagnosis of RD in an eye was associated with a risk of developing fellow eye rhegmatogenous retinal detachment (RRD) (P < 0.001) and tractional RD (P < 0.001), respectively. RRD in an eye was associated with a 17% risk of developing RD in the fellow eye (β = -1.6, OR = 0.202, P < 0.001). The BCVA in the fellow eye of the three types of RD varied significantly (P < 0.001). The fellow eye was blind in 25.2% of RRD, 54.1% of tractional retinal detachment (TRD), and 11.1% of exudative retinal detachment (ERD). Bilateral RD eyes were blind in RRD (85.7%), TRD (71.1%), and ERD (50%). One hundred and seven eyes (40.5%) of the total 264 RD eyes studied had other fellow eye events at the presentation. Conclusion A patient with an RD in one eye is at significant risk of developing a blinding RD in the fellow eye. This risk varies with the type of RD and is highest with TRD. However, RRD, the commonest type of RD, can benefit from prophylactic treatment to the fellow eye RD predisposing lesions.

Abstract
Purpose Altmetrics is a web-based metrics method that measures the online dissemination of an article and the interactions it receives. We aimed to perform a bibliometric and altmetrics analysis of the 100 most cited articles (T100) on vitreoretinal surgery (VRS) published between 2010 and 2020. Methods A detailed search including terms regarding VRS in the Web of Science database was conducted. Articles were examined for bibliometric data and altmetrics. Results T100 articles had citation numbers ranging from 55 to 368 and altmetrics score (AS) values ranging from 0 to 125, and there was no statistically significant correlation between them. AS was weakly correlated with publication year. A statistically weak negative correlation was also found between AS and percent of citable open access, number of years since publication (NYsP), and average citations per year (ACpY). Conclusion AS values of articles on VRS were found to be low. Apparently, this was because the issue was of a highly specific and technical nature. However, the existence of articles with a zero AS value despite high citation numbers suggests that journals and authors do not yet attach enough importance to altmetrics. Altmetric analysis is not a reliable indicator for evaluating the scientific value of an article, and it cannot be a substitute for traditional metrics but it can provide perspective on the social impact of articles.

Moradi Farsani D, Rafieezadeh A, Nourian N, Mohammadi H, Naghibi K, Saghir K. Evaluating the preventive effect of metoclopramide and aminophylline on pain after deep vitrectomy. INTERNATIONAL JOURNAL OF PHYSIOLOGY, PATHOPHYSIOLOGY AND PHARMACOLOGY 2022; 14:316-323. [PMID: 36741202 PMCID: PMC9890202] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Subscribe] [Scholar Register] [Received: 06/30/2022] [Accepted: 11/14/2022] [Indexed: 02/07/2023]
Abstract
BACKGROUND Deep vitrectomy is one of the most frequently performed ophthalmic procedures. Postoperative pain is a common complaint among patients. Consequently, we investigated whether metoclopramide and aminophylline could decrease pain intensity following deep vitrectomy. METHODS This double-blinded clinical trial study that was approved by the Ethical Committee of Isfahan University of Medical Sciences (IR.MUI.REC.1396.3.217) (Thesis Reg. number: 396217) and registered at the Iranian Registry of Clinical Trials (IRCT) (Reg. number: IRCT20170716035104N5, available at https://www.irct.ir/trial/59146) aimed to evaluate 105 patients who were candidates for deep vitrectomy. They were randomly assigned into three groups: metoclopramide (received 0.1 mg/kg diluted in 10 ml of normal saline), aminophylline (received 4 mg/kg diluted in 10 ml of normal saline), and placebo (received 10 ml of normal saline). Postoperative pain was evaluated in all groups. RESULTS The postoperative pain levels of the three groups differed significantly from the start of the recovery to 30 minutes, 60 minutes, 2 hours, and 4 hours postoperatively, with metoclopramide and aminophylline groups experiencing less postoperative pain than the placebo group. Moreover, there was a significant difference between the groups regarding patient satisfaction (P<0.05). CONCLUSION Both metoclopramide and aminophylline significantly reduce postoperative pain after deep vitrectomy, although metoclopramide has a greater effect.

Ophthalmol Retina 2022; 6:1001-1008. [PMID: 35569764 PMCID: PMC9637701 DOI: 10.1016/j.oret.2022.05.004] [Citation(s) in RCA: 2] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/30/2022] [Revised: 04/18/2022] [Accepted: 05/09/2022] [Indexed: 11/22/2022]
Abstract
OBJECTIVE To investigate the mechanical properties of 23-, 25-, and 27-gauge vitrectomy vitrectors across 3 different vitrectomy systems to inform surgical techniques. DESIGN An experimental study that did not involve any human subjects. METHODS Nine vitrectors (3 each of 23-, 25-, and 27 gauge) from Alcon, Dutch Ophthalmic Research Center (DORC), and Bausch & Lomb (B/L) were measured. Measurements were performed using electroforce displacement at the tip and 15 mm from the tip. Five measurements were performed at each location, and fully elastic deformation was ensured. MAIN OUTCOME MEASURES The main parameter being measured was the force in grams (gf) necessary to deflect the vitrectors vertically downward by 1 mm, either at the tip of the vitrector or 15 mm from the tip. RESULTS A total of 90 measurements were performed. Across brands, B/L demonstrated the least stiffness at both the tip and at the 15-mm point for 23-gauge (8.0±0.3gf, 67.3±1.0gf), 25-gauge (6.8±0.3gf, 60.5±0.4gf), and 27-gauge (3.3±0.1gf, 33.9±0.5gf) vitrectors. Although there was only a small decrease in the stiffness in the 25-gauge vitrector compared with the 23-gauge vitrector at the 15-mm point, this difference was statistically significant for Alcon (P < 0.001), DORC (P < 0.001), and B/L (P < 0.001). CONCLUSIONS Based on this study, 25-gauge vitrectors, although larger than the 27-gauge vitrectors and less stiff than the 23-gauge vitrectors, may offer favorable compromise between stiffness and gauge size. However, surgeon experience, preference, and the type of surgery being performed should be paramount when making the final vitrector selection. Knowledge of these mechanical properties may aid surgeons in choosing between gauge size and vitrectomy system to optimize their comfort and efficiency.

Abstract
The current study aimed to investigate diabetic retinopathy (DR) screening and treatment coverages among diabetic patients evaluated through the Brazilian National Health Insurance from 2014 to 2019. The Brazilian Public Health System Information Database was used as the primary data source. DR screening coverage was calculated as the rate of procedures of clinical dilated fundus exam and color fundus photograph over the number of diabetic patients. DR treatment coverage was calculated as the rate of procedures of intravitreal injection, photocoagulation, and panretinal photocoagulation over the number of diabetic patients presumably in need of DR treatment. The overall screening coverage increased from 12.1% in 2014 to 21.2% in 2019 (p < 0.001) with substantial regional discrepancies so that North region was the only one with no changes along the period. The overall treatment coverage increased from 27.7% in 2014 to 44.1% in 2019, with Southeast and Midwest absorbing the demand for service from the North, Northeast and South. Despite an improvement along the past years, both screening and treatment coverages for DR in diabetes patients are ineffective in Brazil. Public health policies should address resources disparities throughout the country aiming to offer same healthcare conditions to patients regardless their geographic location.

Abstract
Purpose To report incidence, clinical presentation, and treatment outcome of full-thickness macular hole (FTMHs) diagnosed post pars plana vitrectomy. Methods We retrospectively reviewed the demographics, best-corrected visual acuity (BCVA), indication for the primary vitrectomy, time to diagnose the secondary FTMH, optical coherence tomographic (OCT) appearance, and treatment outcome of FTMHs, occurring after vitrectomy performed between January 2019 and December 2020. Results Six of 523 vitrectomized eyes developed FTMHs, an incidence of 1.1%. There were five females and one male, mean age of 56.5 years (range 37–85). The indication for primary vitrectomy was rhegmatogenous retinal detachment (RRD) in three eyes, one eye each for sub internal limiting membrane hemorrhage from a ruptured macroaneurysm, vitreous hemorrhage from polypoidal choroidal vasculopathy (PCV), and pre-insertion of Ahmed glaucoma drainage device (GDD). FTMHs occurred within one week to three months after vitrectomy (time from primary vitrectomy to the identification of the secondary MH was a mean of 1.03 months). Mean BCVA in all six MH eyes was log MAR 0.9 (Snellen: 6/54). Anatomical closure was achieved after one surgery in three eyes, two surgeries in 1 eye, after photodynamic therapy (PDT) in the PCV eye, and one patient declined surgery. The mean BCVA in the four surgically closed MH eyes improved marginally from log MAR 0.82 (Snellen: 6/38) to log MAR 0.72 (Snellen: 6/30), mean follow-up 7.6 months. Conclusion Post-vitrectomy FTMH is rare, and RRD was the commonest indication for initial vitrectomy. We observed that all secondary MHs were closed successfully using the inverted internal limiting membrane (ILM) flap technique with limited improvement in vision. The visual outcome of these secondary MHs trails behind that of idiopathic MHs.

Abstract
BACKGROUND AND OBJECTIVE To investigate the reliability and quality of vitreoretinal surgery videos posted on YouTube. PATIENTS AND METHODS A search was made using the keywords "vitrectomy," "retinal surgery," and "vitreoretinal surgery" on YouTube. Total view counts, numbers of comments, likes and dislikes, publishing dates, and source of videos were recorded. Educational quality and accuracy of the video content were evaluated using the DISCERN score, Journal of the American Medical Association (JAMA) scoring system, and Global Quality Scores (GQS). RESULTS There were 208 videos included in the study; 152 (73.1%) videos were uploaded by doctors and 56 (26.9%) videos uploaded by non-doctors. Mean DISCERN, JAMA, and GQS scores were 37.65 ± 10.49 (20-69), 0.82 ± 0.52 (0-4), 2.86 ± 0.86 (1-5), respectively. CONCLUSIONS Vitreoretinal surgery videos on YouTube were of low quality and reliability. Those who want to use YouTube videos as a reference for vitreoretinal surgery should pay extra attention to selection of content. [Ophthalmic Surg Lasers Imaging Retina. 2021;52:478-483.].

Abstract
Purpose To determine the burden of retinal diseases and the degree of visual impairment associated with each disease, amongst Nigerians. Patients and Methods This was a hospital-based multicenter, prospective, cross-sectional, non-comparative study conducted from January to December 2018. Data was obtained from consecutive patients with a retinal diagnosis presenting at the general ophthalmic and specialty retina clinics in four hospitals (three public, and one private teaching eye department) in Nigeria. Biodata, visual acuity and refraction, intraocular pressure, findings on dilated retinal examination, diagnosis and systemic diseases were noted. Degree of monocular and bilateral visual loss associated with each diagnosed retinal disease was summarized and p value was calculated using chi-square test. P < 0.05 was considered significant. Results Eight hundred seventy-six of 8614 patients had a retinal diagnosis; establishing a hospital-based retinal disease prevalence of 9.8%. Male:female ratio was 1.1:1. The mean age of study patients was 49.97 (standard deviation 17.64 years). Mean symptom duration was 21.63 months (standard deviation 41.94). The mean intraocular pressure was 13.87 mmHg. Forty-three different retinal diseases were diagnosed. The most common was retinal complications of diabetes, i.e., diabetic retinopathy (DR) alone, diabetic macular edema (DME) alone and a combination of DR and DME, which accounted for 13.7%, 5.6% and 9.3%, respectively (contributed 28.6% of the entire diagnosis). This was followed by retinal detachment (RD), in 219 eyes (15.4%), dry age-related macular degeneration (AMD) in 124 eyes (8.7%). Nearly half of the eyes were blind or severely visually impaired. Blindness occurred in 34.1% of eyes; severe visual impairment in 8.2% of eyes and 29.7% had normal vision. There were 469 patients who had systemic diseases. The common systemic diseases were hypertension in 169 patients (19.3% of the total number of patients), hypertension and diabetes in 156 patients (18%), and diabetes alone in 98 patients (11.1%). Sickle cell disease was present in 1.5%. Conclusion There is need to invest in infrastructure, local training and development of systems for early detection and treatment of several retinal diseases in sub-Saharan Africa; DR and DME having the largest burden. Collaborative physician care and management of hypertension and diabetes could significantly reduce the burden of DR and DME.
