Needle-Stick Injuries in Ophthalmic Practice.

Purpose: Needle-stick injuries (NSI) are a prominent route by which blood-borne infections are transmitted. The unique microsurgical nature of ophthalmic practice constitutes an additional risk to sustain injury. This study aimed to identify the epidemiological profile of needle-stick injuries in a tertiary eye center and to evaluate the implemented safety policy in preventing sharp injuries. Methods: This was a retrospective cross-sectional study of all sharp injuries that occurred at King Khalid Eye Specialist Hospital (KKESH). Data on all reported sharp injury incidents from 2013 to 2021 were collected. The mechanisms of injury, context, location, and type of prick were collected and analyzed. Also, this study involved an institution-based survey for all ophthalmic staff. Results: Two hundred and one sharp injury incidents were reported over 9 years. Physicians sustained 46.8% (n=94) of injuries, followed by nurses and ophthalmic technicians, 40.8% (n=82) and 7% (14); respectively. Operating and treatment rooms were the locations of 60.7% of incidents, whereas outpatient clinics and emergency rooms accounted for 19.4% and 13.4% of injuries, respectively. Conclusion: The current findings add to the growing body of literature on the importance of NSI prevention and reporting strategies. In the present study, sharp injuries were most commonly encountered by ophthalmic staff in the operating rooms. Continuous staff education on handling sharp instruments, encouraging anonymous reporting, and up-to-date revisions of guidelines and policies are of paramount importance to lessen the burden of sharp injuries.

Angiolymphoid hyperplasia with eosinophilia: a case series and literature review.

PURPOSE: Angiolymphoid hyperplasia with eosinophilia is an uncommon chronic inflammatory condition of unknown etiology. Orbital and adnexal involvement findings are variable and often nonspecific. METHODS AND RESULT: We report six patients with angiolymphoid hyperplasia of the orbit, their clinical and histopathological characteristics, and a review of previously published literature with this diagnosis between 1980 and 2021. CONCLUSION: ALHE has definite histopathologic features but inconclusive radiological studies. The ophthalmologic findings of this entity overlap significantly with other similar variants and may be thought as equivalent lesions.

Corneal Endothelial Toxicity Secondary to Topical 5-fluorouracil.

5-fluorouracil (5-FU) is an important chemotherapy adjunct for the management of conjunctival and corneal dysplasia. Since it is possible for this agent to gain access to the anterior chamber, several reports in the literature have demonstrated 5-FU long-term safety and efficacy. Although recent publications reported that topical 5-FU has no cytotoxic effect on the corneal endothelium, we report a patient affected by bilateral ocular surface squamous neoplasia who has developed significant endothelial density and morphology changes after starting a course of 5-FU.

Surgeons preferences in descemet membrane endothelial keratoplasty (DMEK).

AIM: To explore the attitudes, preferences, and barriers of DMEK among corneal specialists in Saudi Arabia. METHOD: An anonymous survey was sent through an online platform to members of the Saudi Ophthalmological Society. The survey was designed to capture data covering: demographic data, practice patterns of keratoplasty techniques, DMEK technique preferences, barriers, and facilitators to performing DMEK. RESULTS: Thirty-five (33% response rate) surgeons participated in the questionnaire. Sixty-eight percent were in practice for less than or equal to 10 years. Thirteen surgeons were performing DMEK. Participating in any training capacity was observed among surgeons who performed DMEK (92%). The main selection criteria for this procedure were patients with normal anterior chamber anatomy (77%). The main barrier against DMEK adoption among surgeons who do not perform the procedure was the lack of experience (91%). Strategies to help begin performing DMEK were eye banks support (prepared grafts, backup tissue for inadvertent loss), access to wet-lab training courses, and higher surgical volume. CONCLUSION: DMEK is not highly performed among corneal specialists in Saudi Arabia; however, there is evident interest in adopting this technique. Strategies toward filling the gap of lacking experience would facilitate the adoption of the procedure. Eye banks play a crucial role by providing prepared tissues, which would lessen part of the technical difficulty.

Tubercular Episcleritis: A Review of Literature.

Episcleritis is rarely reported to be associated with tuberculosis (TB). In this review, we highlight this underreported entity and elaborate on the natural history of the reported cases in the literature. Eighteen articles were found to describe numerous cases throughout the past century. Forty patients diagnosed with tuberculous episcleritis were found in the literature. The majority of the patients presented with a latent form of TB and fewer cases were linked with active/pulmonary disease. The natural history of episcleritis was found to have chronic and recurrent attacks refractory to traditional treatment, and the most commonly reported type was the nodular form. The described cases were eventually treated by quadruple antituberculous therapy, and fortunately, recurrence after treatment completion was not documented. It is imperative to highlight such entities that may be underreported in endemic countries, as successful therapy would decrease ocular morbidity and prevent potential unforeseen tuberculous complications.

Limbal Autograft Stem Cell Transplantation: More Than 20-Year Follow-up.

Limbal stem cell deficiency (LSCD) is a very challenging situation and difficult to manage. A great works and ideas were conducted over the past 50 years. Numerous surgical techniques were proposed. We are reporting more than a 20-year follow-up of a case of limbal autograft stem cell transplantation due to LSCD secondary to chemical injury.

Risk factors for transposition of the great arteries in Saudi population.

OBJECTIVES: To assess potential risk factors and their effect on the development of transposition of the great arteries (TGA). Methods: A retrospective case-control study of all patients diagnosed with TGA between 1999 to 2016 at King Abdulaziz Medical City, Riyadh, Saudi Arabia. Age and gender-matched controls were selected. Risk factors, including consanguinity, gestational diabetes, family history of congenital heart disease, parental age, and maternal parity, were collected. Regression modeling was used to analyze the effects of risk factors on the development of TGA. Results: A total of 206 patients with transposition of the great arteries were enrolled in the study. Transposition of the great arteries  cases were divided into simple and complex TGA. Selected healthy controls were 446. In the studied cases, consanguinity was found in 95 (46%) of cases, gestational diabetes was diagnosed in 36 (17.5%) mothers, and 35 (17%) had a confirmed family history of congenital heart disease. When risk factors of the cases were compared to the controls, consanguinity, gestational diabetes, maternal age, and parity were found to significantly increase the incidence of TGA. Conclusion: Our study revealed significant risk factors for the development of transposition of great arteries including first degree consanguineous marriages, gestational diabetes, family history of congenital cardiac anomalies, and increasing maternal age and parity. These factors increased the risk by at least 2 folds.
