Did the spectrum of endophthalmitis change? A study comprising 13 years experience with operative therapy of endophthalmitis

Clinical profile of patients with endophthalmitis: A 16- year retrospective, cross-sectional study at tertiary care hospital in Western Saudi Arabia

Aim

This study aimed to profile the clinical features and demographics of patients with endophthalmitis in a tertiary care center, Western region, Saudi Arabia. We used a retrospective cross-sectional case series at King Abdulaziz University Hospital.

Materials and Methods

Endophthalmitis was diagnosed in a total of 14 eyes of 14 patients treated in our hospital between 2002 and 2018. The patients' medical records were reviewed to gather demographic and clinical data.

Results

The mean age of patients was 52.8 ± 19.2 years, and 50% of patients were male. The majority of endophthalmitis cases were post-ophthalmic surgery (50%), 35.7% were of endogenous origin, 7.2% were associated with corneal ulcer with perforation, and 7.2% were post open globe injury. Patients' admission to the hospital ranged from 2 to 10 days from symptoms occurrence with a median of 5 days. Half of the patients presented with no light perception vision, counting fingers in 14.2%, hand motion in 14.2%, light perception in 7.2%, and 20/300 in 7.2%. The final visual outcome improved in four cases (28.5%) with best corrected visual acuity of 20/40 reached in one patient.

Conclusion

Post- ophthalmic surgery and endogenous endophthalmitis were the most common causes of endophthalmitis among our patients, with late presentation to the hospital and poor vision at presentation also being common findings. These findings highlight the necessity of proper patient education, after care and adherence to sterile techniques in ensuring that patients recover successfully from ophthalmic surgery.

Clinical Analysis of 1593 Patients with Infectious Endophthalmitis: A 12-Year Study at a Tertiary Referral Center in Western China

Background:

Infectious endophthalmitis is a severe ocular inflammation which can cause devastating visual loss. The aim of the study was to identify the demographic and clinical features of infectious endophthalmitis in Western China for better prophylaxis and treatment of this disease.

Methods:

A retrospective, cross-sectional study was conducted based on the medical records of inpatients having infectious endophthalmitis in a tertiary referral center in Western China between 2005 and 2016.

Results:

The common cause of infectious endophthalmitis was trauma (82.6%), endogenous (7.8%), ophthalmic surgery (6.9%), and corneal ulcer with perforation (2.7%). These four etiological groups differed in age, gender, enucleation rate, visual outcome, etc. The number of cases in the first 6 years accounted for 38.7% of the total collection, which in the second 6 years accounted for 61.3%. The etiology patterns were different between these two periods. Altogether 51.3% of patients received pars plana vitrectomy, 13.9% of patients underwent evisceration, and the remaining 34.8% received other treatments. Of the 670 cases that had culture results, 266 (39.7%) were culture positive and 177 (66.5%) were Gram-positive organisms, 64 (24.1%) were Gram-negative organisms, 11 (4.1%) had fungal infection, and 14 (5.3%) were infected by multiple pathogens.

Conclusions:

There was an upward trend of the occurrence of infectious endophthalmitis in Western China for the past decade. The demographic and clinical characteristics of infectious endophthalmitis in Western China had its own characteristics and differed from those of developed countries. Here, open globe trauma was the most common cause of endophthalmitis, most traumatic endophthalmitis patients were male, and most of the injuries were work related, implicate that we should strengthen the education and application of ocular safety regulation specifically targeting the workplace.

Clinicopathologic review of pediatric enucleations during the last 50 years

PURPOSE

To evaluate diagnoses leading to enucleations in the pediatric age group over time.

METHODS

All pathology reports of enucleation specimens at the University of California-San Francisco eye pathology laboratory from children (ages 0 to 18 years) from 1960 to 2008 were reviewed. The main outcome measures were the frequency of pediatric enucleation specimens in each diagnostic category as compared with total pathological laboratory volume over time, and the age and gender distribution of histopathological diagnostic categories over time.

RESULTS

Specimens of 746 eyes from 729 pediatric patients were analyzed. Pediatric enucleated eyes constituted 2.7% of all specimens received at the pathology laboratory. The overall frequency of pediatric enucleation specimens did not change over time. Retinoblastoma specimens increased by a factor of 2.9 over time (p < 0.0001). The increase in retinoblastoma was offset by a decrease in nonretinoblastoma enucleations, which decreased by a factor of 3.8 between the 1960s and 2000s (p < 0.0001), driven by a decrease in enucleations caused by trauma (p < 0.0001). Beginning in the 1980s, pediatric enucleations caused by nonrhegmatogenous retinal detachment, nematode and non-nematode endophthalmitis, and congenital glaucoma decreased significantly. Retinoblastoma was the most common diagnosis overall (45%), in girls (60%), and in ages <5 years (78%). Trauma was the second most common diagnosis (32%) and the most common in boys (42%) and in children ages 6-12 (58%) and 13-18 (72%) years.

CONCLUSIONS

A decrease in pediatric nonretinoblastoma enucleations was observed over time, possibly attributable to better diagnostic capabilities, surgical techniques, and public health interventions. The increase in retinoblastoma enucleations over time was likely due to the result of institutional referral bias.

[Primary vitrectomy with intraocular antibiotic application in postoperative endophthalmitis]

PURPOSE

Pars plana vitrectomy with intravitreal antibiotic application is an established procedure for treating postoperative endophthalmitis. The presented study analyzes our own results with this treatment as well as the role of adjuvant systemic steroid treatment.

METHOD

We analyzed the data of 34 consecutive patients with postoperative endophthalmitis from January 2000 to March 2006. Thirty-two patients underwent vitrectomy and intravitreal application of antibiotics, and two patients received intravitreal antibiotics only. All patients received intravitreal dexamethasone and systemic antibiotics, and 12 patients received the systemic treatment with prednisolone. The effect of vitrectomy with respect to final visual acuity and the rate of postoperative complications were analyzed. The vitreous was microbiologically examined. Postoperative follow-up time ranged from 2 weeks to 24 months.

RESULTS

Endophthalmitis followed cataract surgery with intraocular lens implantation in 30 patients (89%) and followed pars plana vitrectomy in four patients (11%). Positive cultures were obtained in 19 (56%) patients. Visual acuity improved in 31 (91%) patients. At their final examinations, 27 (79%) patients had gained visual acuity of 0.05 or better.

CONCLUSIONS

CONCLUSION

Immediate vitrectomy in combination with intraocular antibiotics and steroid administration resulted in preservation of ambulatory vision in most of the patients. Systemic postoperative therapy with steroids seems to be associated with better final visual acuity.
