PURPOSE: Retinopathy of prematurity (ROP) is becoming a leading cause of preventable blindness. The current study aimed to assess ROP and its risk factors in Tabuk City, Northern Kingdom of Saudi Arabia. METHODS: A retrospective study was conducted in King Khalid Hospital, Tabuk City, Saudi Arabia. The premature infants' records during the period of January 2016 to April 2018 were approached. One hundred and eight records were eligible; the infants' gestational age, weight, if received oxygen, surfactant use, blood transfusion, intraventricular hemorrhage, and patent ductus arteriosus were reported. Chi-square test was used to compare premature infants and their counterparts regarding various risk factors. P < 0.05 was considered statistically significant. RESULTS: Out of 108 premature infants, 33.3% had ROP (Many were sightthreatening [stages required treatment] and more than twothirds involving both eyes); a statistically significant difference ( P < 0.05) was evident between infants with prematurity, and low birth weight. No significant differences were found regarding other risk factors ( P > 0.05). Only 8.3% received interventional therapy. CONCLUSION: ROP is common in King Khalid Hospital, which is the referral tertiary hospital in Tabuk city, KSA . The low birth weight is a significant risk factor to develop ROP. Many of ROP cases were sightthreatening (cases that required treatment) and most cases involving both eyes. Treatment availability at Tabuk city is recommended, instead of referral to another centers especially among those with low weight at birth.

Incidence of cataract differed depending on anatomic and etiologic diagnoses of uveitis. There is a significant association between severity of inflammation at presentation and development of cataract.

Purpose This study aims to measure the knowledge levels toward retinopathy of prematurity (ROP) among pediatricians covering neonatal intensive care units (NICUs) in the major hospitals in Tabuk, Saudi Arabia. To our knowledge, this is the first report to assess the awareness level of ROP in the NICU pediatricians in the region. Patients and Methods This is a quantitative, non-experimental, cross-sectional, descriptive study using self-administered electronic questionnaires to assess the knowledge level among NICU pediatricians at the main hospitals of Tabuk city. We used a self-administer online validated knowledge, attitude, and practice (KAP) questionnaire. A scoring system was implemented in the data analysis, depending on the correct chosen answers on the KAP questionnaire, to present the ROP knowledge level in the participants. Results The study included 41 NICU pediatricians. Most of the participants’ age exceeded 40 years (51.2%). The majority were recruited from either King Salman Military hospital (34.1%) or King Khalid hospital (31.7%). The average frequency of preterm infants seen per month exceeded 15 infants among 41.4% of the respondents. Most pediatricians recognized the important treatment modalities available for ROP (92.7%); however, only 24.4% of them could recognize that 32 weeks or less is the gestational age of the screening criteria for ROP. The overall knowledge score ranged between 4 and 10, out of a possible maximum of 12 with a mean ± SD of (6.68±1.47). The majority (75.6%) believe that the ROP treatment can successfully prevent blindness. Conclusion Our study demonstrated that the NICU pediatricians have good knowledge about the treatment modalities of ROP. However, their knowledge about the inclusion criteria of ROP screening was insufficient. Thus, we highlighted the necessity of raising the awareness level and the strict application of the clinical guidelines among NICU pediatricians and healthcare workers involved in managing ROP.

Heat shock response is an essential cellular stress response. Dysregulation of various heat shock proteins (HSPs), within the heat shock response (HSR) pathway, play a vital role in this host-defense mechanism contributing to obesity-induced insulin resistance and type 2 diabetes (T2D). Previously, we have reported changes in the expression levels of several HSPs such as HSP40, HSP60, HSP70, and HSP90 in obese compared with lean individuals. DNAJC27 is a member of the HSP40 protein family that was previously identified as a body mass index (BMI) associated locus in genome-wide association (GWAS) studies. However, not much is known about the changes in DNAJC27 expression levels in obesity and T2D. In the present study, we aimed at understanding changes in DNAJC27 expression levels in plasma, peripheral blood mononuclear cells (PBMCs) and adipose tissue in association with obesity and T2D. A total of 277 individuals enrolled including 160 non-diabetic (96 non-obese and 64 obese) and 117 T2D (45 non-obese and 72 obese) individuals. Plasma level of DNAJC27 was significantly higher in obese individuals (6.28 ± 0.64 ng/mL) compared with non-obese individuals (4.8 ± 0.45 ng/mL) with P = 0.043. Dividing the population based on diabetes status showed that there was a significant increase in the plasma level of DNAJC27 in obese (6.90 ± 1.3 ng/mL) compared with non-obese individuals (3.81 ± 0.43 ng/mL) (P = 0.033) in the non-diabetic group. Similarly, DNAJC27 expression level was also higher in PBMCs and adipose tissue of obese individuals. DNAJC27 was found to be associated with leptin and resistin, adipokines known to be dysregulated in obesity, that stimulate inflammatory processes leading to metabolic disorders. In conclusion, our data show that DNAJC27 is elevated in obese and T2D individuals and was positively associated with obesity biomarkers such as leptin and resistin suggesting that this protein may play a role in the pathophysiology of these disorders.

Purpose: To assess the satisfaction and competency of Saudi ophthalmology residents and compare their performance against International Council of Ophthalmology (ICO) standards. Methods: A cross-sectional web-based survey of senior ophthalmology residents (postgraduate years [PGY] 3-4) and recent graduates (from 2010 to 2015) assessed various aspects of training. The questionnaire was sent to the participants and was divided into 3 main domains: demographics, training program evaluation, and preparedness for board exams and clinical practice. Results: Out of the 145 invitees, 120 (82.8%) responded. Fifty percent of respondents reported an overall satisfaction with the program. Adequate clinical exposure was reported in most subspecialties except refraction and low vision rehabilitation with inadequate exposure reported by 55.8% and 95.8%, respectively. Surgical exposure was reported as adequate for phacoemulsification (58.3%) and strabismus surgery (68.3%) only. Eighty-nine percent of respondents reported performing less than 80 cases of phacoemulsification. Of the respondents who had graduated, most (89.7%) passed the final board exam at the first attempt. There were 73.5% of respondents who reported that residency training prepared them well for the board exam. Ongoing clinical and call duties were reported as having a negative impact on exam performance. Conclusions: Saudi ophthalmology residents demonstrate a high level of clinical competency. However, additional efforts should aim at improving surgical training to increase the level of satisfaction among residents and improve the quality of training to meet international standards.

PURPOSE: To review students’ perceived symptom-based computer vision syndrome (CVS) and its determinants and to suggest preventive measures. METHODS: This cross-sectional survey was conducted in 2021 at a university in Central Saudi Arabia. The presence and severity of symptoms related to CVS were investigated. The total CVS symptom score was the outcome variable. The CVS score was correlated to participants’ demographics, visual habits when using digital devices, and knowledge about CVS. Due to skewed distribution, a nonparametric method was used for analysis. RESULTS: Overall, 521 students were surveyed. The prevalence of CVS based on at least one symptom was 96% (95% confidence interval 94.3–97.7). The median score was 8.0 (interquartile range 4.0–12.0). Of the 24 possible CVS scores, 42 students (8%) had scores of 18 or more (severe CVS). Being female (Mann–Whitney [MW] P < 0.001), being older (Spearman P < 0.001), refractive error (MW P < 0.001), the presence of dry eye (MW P < 0.001), using devices other than a desktop computer (KruskalWallis) P = 0.03), and more than 6 h constantly working with a device (MW P = 0.001) were correlated with a higher CVS score. Older age, female, refractive error, and using digital devices for more than 6 h were the independent and significant predictors of CVS in college students. CONCLUSION: Most of the students suffered from mild-to-moderate CVS symptoms. Health promotion for prevention and periodic ophthalmic consultations are recommended. Identified predictors should be the focus when implementing strategies to combat CVS in the adolescent Saudi population.

Introduction: Suprachoroidal hemorrhage is an unexpected complication after penetrating keratoplasty during childhood. We report the case of delayed suprachoroidal hemorrhage after penetrating keratoplasty in a neonate as the first manifestation of hemophilia. Case report: A 4-day-old neonate was referred to our hospital because of bilateral corneal opacities present since birth. A diagnosis of bilateral Peter’s anomaly type 2 with right eye corneal perforation was made after examination. Appropriate treatment was commenced, and later, right eye therapeutic penetrating keratoplasty combined with lensectomy, and anterior vitrectomy was performed. This was complicated postoperatively with suprachoroidal hemorrhage and retinal detachment. Conservative management was advised due to poor visual prognosis. Three months later, the patient was found to have high intraocular pressure in the left eye and glaucoma surgery was recommended. Proper hematological investigations before glaucoma surgery in the left eye revealed a low level of factor VIII with normal levels of factor IX and von Willebrand’s factor antigen. Therefore, a diagnosis of hemophilia type A was established. Conclusion: This case serves as a reminder that the occurrence of suprachoroidal hemorrhage, especially in the absence of other predisposing risk factors, should warrant detailed systemic assessment to exclude underlying bleeding disorders.
