Incidence of Sympathetic Ophthalmia after Inciting Events: A National Database Study in Japan.

PURPOSE: To analyze the incidence of sympathetic ophthalmia (SO) after inciting events (eye trauma or intraocular surgery). DESIGN: Retrospective cohort study. PARTICIPANTS: Patients experiencing inciting events between 2012 and 2019. Onset of SO was defined as the first date of SO diagnosis. METHODS: Using a nationwide administrative claims database in Japan, we calculated the cumulative incidence of SO after inciting events stratified by sex, 10-year age groups, and a categorical variable of primary or repeated, reflecting the history of inciting events in the past year (no inciting events, inciting events without trauma, or inciting events with trauma) using the Kaplan-Meier approach. We also estimated the adjusted hazard ratio (aHR) by Cox regression. We then restricted the population to those with only 1 inciting event during the observation period to investigate the pure effect of each inciting event. MAIN OUTCOME MEASURES: Cumulative incidence of SO over 60 months. RESULTS: A total of 888 041 inciting events (704 717 patients) were eligible. The total number of SO cases was 263, and the cumulative incidence of SO was 0.044% over 60 months. Female sex was not associated with onset of SO (aHR, 1.01; 95% confidence interval [CI], 0.79-1.29; P = 0.95). The group 40 to 49 years of age showed the highest incidence of 0.104% among the age groups (aHR vs. ≥80 years of age group [0.041%], 2.44 [95% CI, 1.56-3.80]; P < 0.001). Repeated inciting events with and without trauma showed higher incidences of SO (0.469% and 0.072%, respectively) than primary inciting events (0.036%) (aHR 11.68 [7.74-17.64] and 2.21 [95% CI, 1.59-3.07], respectively); P < 0.001 and P < 0.001, respectively). The incidence of SO after vitrectomy was much lower than after trauma (0.016% vs. 0.073%), and the incidence after scleral buckling was even lower. CONCLUSIONS: The cumulative incidence of SO over 60 months was estimated to be 0.044% at minimum. Repeated inciting events, especially those with trauma, increased the risk of SO developing. Trauma was 4 to 5 times as likely to induce SO than vitrectomy. The present findings will be valuable for counseling patients about the risks of SO after trauma and before performing intraocular surgeries.

National Health Care data system analysis of glaucoma surgery activity in France in 2016.

PURPOSE: To describe the glaucoma surgery offer in France in 2016. METHODS: We used the French National Health Care System database to identify all medical procedures carried out in 2016. The study investigated the entire population aged 30 years and older that had undergone glaucoma surgery, alone or combined with another surgery. We calculated the incidence of surgeries per 100 000 inhabitants 30 years of age and older performed by ophthalmologists carrying out at least 50 procedures annually, the number of surgeons doing these surgeries, the mean age of these practitioners, and the number of surgeons older than 55 years. RESULTS: In 2016, 16 854 glaucoma surgeries were performed in patients aged 30 years and older, for an incidence of 40.8 per 100 000 inhabitants aged 30 years and older. The most frequent procedure performed was trabeculectomy followed by non-penetrating deep sclerectomy (16.7 and 11.7, respectively, per 100 000 inhabitants 30 years of age and older). Private practice glaucoma surgery accounted for 47% of the activity of surgeons performing at least 50 surgeries per year and 60% of the total surgical activity. Of the private practice ophthalmologists performing at least 50 glaucoma surgery procedures per year, 58.5% were over 55 years of age, and 23.5% of public hospital ophthalmologists were over 55 years of age. CONCLUSIONS: This study demonstrates that surgeons performing glaucoma surgeries are often older. It is necessary to take note of the country's educational capacity to ensure that the number of ophthalmological surgeons remains adapted to demand.

Right services to right patients at right time in right setting in Tays Eye Centre.

PURPOSE: The report describes the concepts behind procedures implemented in Tays Eye Centre to enable improved access to care and improved productivity. METHODS: The strategy was developed in 2009 after hospital district decided to construct a new eye hospital which was opened in 2012. The following principles were implemented: (i) identification of high-volume patient groups: the 'big four' eye diseases accounting for 70% of patient visits and costs: age-related macular degeneration (AMD), glaucoma, retinal diseases and cataract; (ii) stratification and prioritization of patient care based on risk of permanent visual disability; (iii) standardization of services for low-risk patients; (iv) maximization of productivity; and (v) shared care. The impact of the new strategy on access to care and productivity is reported for years 2011-2015. RESULTS: In 2011-2015, the total number of services provided increased 46% while the work contribution increased 15%. The number of referrals increased 76% and the number of outpatient appointments increased 2.5-fold. Simultaneously, the number of delayed follow-up visits decreased to zero. Age-related macular degeneration (AMD) injections increased 1.8-fold. However, after 50% yearly increase in Age-related macular degeneration (AMD) injections, a plateau was reached in 2014 with a 3% decline in 2014-2015 with no changes in treatment indications. In the beginning of 2016, the number of injections has started to increase again (+9% compared to 2015).  The total number of surgical procedures increased 98%. The annual number of cataract surgeries increased 64% and bilateral surgeries from 11% to 39%. CONCLUSION: Revised operational concepts and new facilities together with a 15% increase in work contribution led to a 46% increase in overall productivity, improved access to care and the clearance of delayed services. Efforts continue to further refine cost-effective care and to define the appropriate levels of services.

Management of congenital nasolacrimal duct obstruction--latin american study.

PURPOSE: To survey the management of congenital nasolacrimal duct obstruction, in particular, the timing of intervention and the use of massage, probing, nasolacrimal intubation, nasal endoscopy, and dacryocystorhinostomy. METHODS: This was an exploratory study that used an electronic questionnaire, which was sent via Internet to the members of Ojoplast, a social network composed of ophthalmologists from several Latin American countries. The responses were analyzed using adherence and the chi-square test. RESULTS: Seventy-two completed questionnaires were received. Approximately 64% of survey participants indicated that they use massage as the initial treatment for congenital nasolacrimal duct obstruction until 1 year of age and lacrimal probing (70.8%) for patients >1 year of age. Early probing used by 58.3% of the patients for a dilated lacrimal sac, and 66.7% reported that lacrimal system probing in conjunction with irrigation is effective. If the probing is not effective, 65.3% indicated that they repeat the procedure a second time. If the patient does not respond to massage or probing, 69.4% perform lacrimal system intubation. Sixty-two percent of the respondents indicated that they perform dacryocystorhinostomy for cases in which probing or intubation is not effective. CONCLUSIONS: The members of Ojoplast adopt massage as the initial treatment for congenital nasolacrimal duct obstruction for patients <1 year of age. Probing is performed on patients >1 year of age, and early probing is used only for cases of dilated lacrimal sac. When massage and probing are not effective, intubation is performed, and if intubation is unsuccessful, dacryocystorhinostomy is performed, in which the external approach to dacryocystorhinostomy is used most often.

Waiting times for eye surgery at a Toronto teaching hospital.

BACKGROUND: Waiting times for eye surgery in Ontario have increased dramatically in recent years. We performed a study to compare the waiting times, the amount of operating time and the number of cases performed for various eye surgical procedures in 1999, 2000 and 2001 at a major Toronto teaching hospital. METHODS: For 3 months (May, June and July) of 1999, 2000 and 2001, eye surgeons at the hospital reported how long their patients had to wait for surgery and how many patients they had waiting for surgery. The number of operating hours for eye surgery and the number of eye surgery cases in fiscal years 1999-2000, 2000-01 and 2001-02 were collected from a hospital database. Surgical procedures that were captured were cataract extraction, corneal transplantation, trabeculectomy (including phacotrabeculectomy), vitreoretinal surgery and adult strabismus surgery. RESULTS: All surgeons responded to the survey. Median waiting times increased for all types of eye surgery between 1999 and 2001. The median wait for cataract extraction increased by 92%, from 3.0 to 5.8 months. For corneal transplantation the median wait doubled, from 5.5 to 11.0 months. The median wait for trabeculectomy increased by 60%, from 2.5 to 4.0 months. The median wait for vitreoretinal surgery almost tripled (191%), from 1.2 to 3.4 months. For adult strabismus surgery the median wait increased by 56%, from 8.0 to 12.5 months. Operating time was cut by over 1000 hours (from 5481 to 4434) from 1999-2000 to 2000-01 and then again, by 255 hours, from 2000-01 to 2001-02. Despite this, the number of surgical procedures performed decreased only slightly over the study period, from 4292 to 4099. INTERPRETATION: The waiting times for all eye operations increased substantially between 1999 and 2001 at this Toronto teaching hospital. In addition, for each type of surgery the median waiting time was longer than the Ontario median, by 13% (cataract surgery) to 191% (vitreoretinal surgery). The fact that the number of cases performed decreased only slightly despite a dramatic decrease in operating time indicates that there was an increase in efficiency. Possible ways to reduce the long waits include implementing prioritization programs, increasing operating time and moving cataract surgery out of the hospital to a day surgical centre.
