Assessment of the Level of Knowledge and Awareness of the Risk of Chronic Use of Steroids in Causing Cataracts Among the General Population in the Western Region of the Kingdom of Saudi Arabia (KSA): A Cross-Sectional Study.

BACKGROUND/AIM: Cataracts consequence blindness to burden and impose health and economic burdens on communities. Steroid-induced cataracts have scarcely been highlighted in previous literature, creating a demand for reinvestigating this issue among the general population of western Saudi Arabia. METHODS: A cross-sectional study was conducted in 2022 using an online survey distributed among the target participants via social media platforms. The data were gathered and statistically analyzed using IBM Corp. Released 2015. IBM SPSS Statistics for Windows, Version 23.0. Armonk, NY: IBM Corp. software. RESULTS: Overall, 866 respondents (males = 42.5%, females = 57.5%) were enrolled in this survey (mean age = 28.08, SD = 13). The participants' correct responses to questions about steroid-induced cataracts showed inadequate representation (below 50%). Additionally, most of the participants (94.23%) had a poor understanding of steroid-induced cataracts. CONCLUSION: The participants' level of understanding of the risk factors associated with chronic steroid usage and its impact on cataracts was inadequate.

Ocular Chemical Injuries in Western Saudi Arabia: A Study of the Public's Level of Knowledge and Experience.

BACKGROUND: Chemical burns are potentially blinding eye injuries and are serious ocular emergencies that necessitate prompt evaluation and treatment. AIM: This study aimed to evaluate the knowledge and experience of the current practice of ocular chemical injuries among the general population in western Saudi Arabia. METHODS: An electronic self-administrated structured survey was distributed among citizens using social media channels in November 2022. RESULTS: This survey includes 929 participants from western Saudi Arabia. Most of the participants were more than 20 years old (82.7%), while females represented 82.7%. Most participants reported an inadequate level of awareness about previous hearing of ocular chemical injury terms compared with their level of knowledge, in which the majority (56.62%) showed a good level of understanding. Female participants, participants 20 years old or older, and Saudis corresponded significantly with a good level of knowledge (p-values <0.001, <0.00, and 0.025, respectively). CONCLUSION: This study showed a fair level of knowledge compared to awareness, which can be improved by further national studies in the Saudi region. We recommend expanding the studies' findings and developing suitable interventions, like health awareness campaigns about ocular chemical damage and prompt corrective measures.

Correlation of Central Macular Thickness and the Best-Corrected Visual Acuity in Three Months After Cataract Surgery by Phacoemulsification and With Intraocular Lens Implantation.

Purpose To estimate the incidence of central macular edema (CME) following cataract surgery and to correlate the central macular thickness (CMT) to the best-corrected visual acuity (BCVA). Methods This cohort study in 2018-2019 included cataract grades I and II. They were operated by phacoemulsification and intraocular lens implantation. CMT was measured using spectral-domain optical coherence tomogram (OCT) before and for three months at one-month intervals after surgery. The change in BCVA and CMT were correlated at three months after surgery. Incidence of CME (more than two SD of pre-surgery CMT) was calculated. Results The mean CMT for 138 eyes operated for cataracts measured before and at one, two, and three months after uneventful surgery was 213 ± 24.9, 222.7 ± 25.5, 217.8 ± 34.8, and 215 ± 28.3 µ, respectively. The median BCVA at three follow-ups was 0.2 (interquartile range [IQR] 0.1; 0.2), 0.1 (IQR 0.0; 0.1), and 0.0 (0.0; 0.03), respectively. The incidence of CME at one and three months was 18% and 4.3%, respectively. The CMT and VA (LogMAR) one month after cataract surgery were significantly correlated (r = 0.4, Pearson P < 0.001). The visual improvement between one and two months post-surgery was not significantly correlated with CMT decline (r = 0.06, Pearson P = 0.5). The BCVA at one, two, and three months was 0.0 LogMAR in 28 (20.3%), 52 (37.7%), and 104 (75.4%) eyes, respectively. Linear regression model, age and diabetes are the risk factors at one month. At two and three months, no significant risk factors were found. Conclusion CME post-cataract surgery seems to be transient. CMT changes correlate with best-corrected vision changes and seem to be affected by age and presence of diabetes in the 1st month after surgery.

Efficacy of Pneumatic Retinopexy in Treating Rhegmatogenous Retinal Detachment at King Abdullah Medical City in Makkah, Saudi Arabia - A retrospective cohort study.

INTRODUCTION: The aim of this study was to present the clinical presentation and short-term outcomes of uncomplicated rhegmatogenous retinal detachment managed by pneumatic retinopexy at a tertiary eye hospital in western Saudi Arabia. MATERIALS AND METHODS: This one-armed retrospective cohort study evaluated selected cases of rhegmatogenous retinal detachment managed by pneumatic retinopexy between 2017 and 2018. Data were collected on patient demographics, preoperative ophthalmic assessment, surgical details, follow up at six months postoperatively, complications and the need for additional surgery. Anatomic success was defined as retinal attachment at 6 months and functional success was defined as vision >20/200 at six months postoperatively. The association of lens status and concomitant laser treatment to anatomical success rates were evaluated. RESULTS: The study sample consisted of 15 eyes with rhegmatogenous retinal detachment in the upper quadrant. In 14 cases, C3F8 gas was used. Anatomic and functional success was noted in 73.3% [95% confidence interval (CI) 51.0: 95.7] and 86.7% (95% CI 69.2; 100) of eyes, respectively. The association between anatomical success and lens status was not significant [RR = 4.5 (95% CI 0.6 ; 37.5), P=0.1]. There was no significant association between anatomical success and concomitant laser treatment. [RR = RR = 1.7 (95% CI 0.7 ; 4.0), P=0.2]. A 2nd retinal surgery was not required in 33.3% of eyes (95% CI 9.5 ; 57.2). CONCLUSION: If stringent selection criteria are used for managing rhegmatogenous retinal detachment with pneumatic retinopexy, anatomical and functional success by six months postoperatively is achieved in the majority of cases. Additional surgeries could further improve outcomes.

Indolent keratitis due to fungus of Malbranchea species. A case report.

INTRODUCTION: Keratitis caused by saprophytic fungi is on the rise in rural areas, often caused by ocular trauma with wooden objects. Early detection of causative organisms and sustained, supervised management can prevent visual disabilities. CASE PRESENTATION: A middle-aged patient from a rural, semi-arid region who presented with pain, redness, and a foreign-body sensation in his left eye resulting from a corneal ulcer induced by trauma from a wooden stick. Due to a history of uncontrolled diabetes and progression of his corneal lesions, he was admitted to our institution for treatment of infectious keratitis. Microbiological examination of corneal scrapings revealed thin, septate hyaline hyphae without conidia or conidiophores, and the patient was diagnosed with a fungal keratitis caused by a Malbranchea species. Though the patient initially responded to treatment with topical natamycin, his condition worsened. He was subsequently successfully treated with topical amphotericin B (1 mg/mL) twice hourly and systemic antifungals. Four months after discharge, the patient returned with symptom recurrence. CONCLUSION: We report the case of a patient with a Malbranchea species causing a rare and recurrent fungal keratitis with corneal infiltrates, subsequently cured by medical management with salvaging of his vision. In patients with a suspected fungal keratitis, early treatment is crucial and should be combined with tight glycemic control for as long as 6 months after presentation to avoid recurrence.

Dermatologists' Knowledge and Attitudes Toward Dry Eye Disease, Refractive Surgery, and Contact Lenses When Prescribing Isotretinoin in Saudi Arabia.

PURPOSE: This study assesses the knowledge and attitudes of dermatologists in Saudi Arabia with regard to dry eye disease, refractive surgery, and contact lenses when prescribing isotretinoin. METHODS: A total of 150 dermatologists from major cities in Saudi Arabia were included in this cross-sectional study. Data were collected through a consent interview questionnaire. RESULTS: Of the 150 dermatologists who participated, 77 (51.3%) were men. Seventy-three (48.3%) dermatologists always prescribed isotretinoin to patients and 71 (47.3%) sometimes prescribed it. One hundred forty-six (97.3%) dermatologists self-reported their awareness of the ocular side effects of the drug. One hundred twenty (80.0%) responded that it was not important to refer patients to an ophthalmologist for an eye examination before starting the isotretinoin course. Lubricant eye drops were routinely prescribed by 96% of the respondents during the isotretinoin course. Fifty (33.3%) dermatologists rarely or never asked patients about recent refractive surgery before starting the isotretinoin course. Sixty-six (44%) dermatologists rarely or never warned their patients to avoid refractive surgery for at least 6 months after the isotretinoin course is completed. One hundred ten (73.3%) dermatologists always informed their patients of contact lens intolerance as a result of isotretinoin use. CONCLUSION: Almost all participants prescribed lubricant eye drops routinely. Most participants self-reported their knowledge regarding the ocular side effects of isotretinoin; however, more than a third did not inquire about recent refractive surgery before starting the course, and less than half did not warn patients not to undergo refractive surgery 6 months after the end of the course. This demonstrates that a significant proportion of dermatologists do not follow the appropriate practices with respect to refractive surgery when they prescribe isotretinoin. Improving the dermatologists' awareness regarding isotretinoin prescription practice is essential with respect to laser refractive surgery to prevent ocular damage.

Corneal parameters 18 Months following collagen cross-linkage treatment (CXL) for keratoconus in western Saudi Arabia: A prospective cohort study.

INTRODUCTION: keratoconus is a common disease in the general population, with prevalence ranging up to 200 per 100 000 with a reported increase in Saudi Arabia. Collagen Cross-Linkage is now an established treatment in isolation and in conjunction with other modalities for managing keratoconus. Our aim is to evaluate using a cohort study the impact of the treatment over a course of 18 months. METHODS: To evaluate the impact of 18 months after collagen cross-linkage treatment and its determinants in eyes with keratoconus in Western Saudi Arabia. A one-armed prospective cohort study design on 45 patients with Stage I, II, III and IV keratoconus who were treated by Collagen Cross-Linkage modality was developed at our institute between 2018 and 2019 to establish the success rate of corneal ectasia stabilization of the disease. RESULTS: Demographic data and grades of keratoconus (Amsler - Krumiech classification) at presentation were correlated to changes in corneal parameters 18 months after CXL compared to that at presentation. Stage I, II, III and IV keratoconus were 13, 14, 2 and 16 eyes respectively. The study showed that the K max significantly declined (P = 0.05) while spherical equivalent refractive status changed from median -1.5D to -2.27D (P = 0.002). Meanwhile, Central corneal thickness significantly reduced (P = 0.001). CONCLUSION: CXL can prove to be efficient in the treatment of Keratoconus and more studies should study ways to improve and implement this treatment plan to such patients.

Prevalence and causative agents of allergic conjunctivitis and its determinants in adult citizens of Western Saudi Arabia: A survey.

PURPOSE: To estimate the prevalence of allergic conjunctivitis (AC) and its related allergic ailments among Saudi adults in the western region. METHODS: Adult population of Taif, Makkah, and Jeddah cities was surveyed from 2017 to June 2018. Subjective questionnaire was used to collect the response. Participants were asked about symptoms (redness, itching, watering, based diagnosis and details of AC, treatment taken in the pasts, and associated conditions, such as allergic asthma and rhinitis). The age-sex-adjusted prevalence, its determinants, and associations to other ailments were assessed. RESULTS: We surveyed 2187 participants (mean age 26.0 ± 9.1 years). The age-sex-adjusted prevalence of AC was 70.5% (95% confidence interval [CI] 68.6-72.4). There could be 2.1 million AC patients among 3.1 million adult populations in Western KSA. It was significantly higher in females compared to males (odds ratio [OR] = 1.7 [95% CI 1.4-2.2]). The risk of AC did not vary by age group (χ 2 = 2.5, df = 3, P = 0.1). The variation of AC in three provinces was not significant (χ 2 = 0.3, df = 3, P = 0.6). Dust (42.6%) and unknown (24.8%) allergens were the main causative agents of AC. AC was significantly associated to asthma (OR = 2.8) and allergic rhinitis (OR = 2.2). CONCLUSION: AC affects seven in ten adults in Western Saudi Arabia. AC is positively associated to allergic rhinitis and bronchial asthma. Public health policies at primary eye-care level should focus on early detection and care of persons with AC.

Prevalence and Determinants of Color Vision Defects among Preparatory University Students at Makkah, Saudi Arabia.

PURPOSE: To estimate the magnitude and determinants of color vision defects (CVD) among preparatory health science students. METHODS: A cross-sectional survey was conducted in 2017. Participants were assessed using 24-plate Ishihara's Test of Color Vision chart. If ≤9 plates were read correctly, the color vision was regarded as deficient. The CVD prevalence and its 95% confidence interval (CI) were calculated. CVD was associated with gender, family history of CVD, and other vision problems. RESULTS: We evaluated 1126 students (552, 49% males; mean age: 18.7 ± 0.7 years). The prevalence of CVD was 1.77% (95% CI: 1.0, 2.6). Among male students, it was 3.5% (95% CI: 1.9, 5.0). Only one female student had CVD. The Duran CVD was found in 18 (1.6%) students. However, only two students had Tritan CVD. Three among twenty CVD students knew that they suffer from CVD. CVD was positively associated to a family history of CVD (odds ratio [OR] = 3.8; 95% CI: 1.4, 10.1;P = 0.02) and male gender (OR = 20.4 [95% CI: 2.7, 153]). CVD was not significantly associated to other vision problems (OR = 0.8 [95% CI: 0.3, 2.0]). CONCLUSION: Eighteen in thousand health sciences students suffered from CVD. Ten percent of them had Tritan CVD. Duran CVD seems to be a male sex-related and/or a familial condition. Most of the CVD students seem to have adopted to this defect and were not aware of suffering from it. Screening for CVD is therefore debatable.

Long-term use of 0.003% tacrolimus suspension for treatment of vernal keratoconjunctivitis.

PURPOSE: To evaluate the safety and efficacy of 0.003% tacrolimus suspension for the treatment of refractory vernal keratoconjunctivitis (VKC). MATERIALS AND METHODS: This prospective study included 40 eyes of 20 patients with severe VKC. After discontinuing all other medications, patients were treated with varying doses of 0.003% tacrolimus suspension. All were followed for at least 24 months. Changes in signs and symptoms after treatment were evaluated; adverse events were assessed. The clinical response to the treatment was the most important measurement to achieve the conclusion. RESULTS: The mean age of the patients was 15.7 ± 1.4 years. Two patients discontinued treatment due to severe burning sensation and were excluded from the study. Significant improvements in all signs and symptoms, including itching, foreign body sensation, papillae, and Trantas dots, were seen in all patients 6 weeks after starting topical tacrolimus. Itching was the first symptom to improve. Treatment was gradually reduced, and intervals were increasing between applications. Recurrence occurred in all patients who attempted to discontinue treatment. No additional medications were required to provide relief, and no significant changes in visual acuity or refraction were seen. CONCLUSIONS: The safety and efficacy of 0.003% Tacrolimus suspension treatment for refractory VKC were achieved and it can be considered a useful option instead of steroids, despite the poor compliance in few patients due its adverse effects.

Endoscopic anatomy of the lacrimal sac for dacryocystorhinostomy. A cadaveric study.

OBJECTIVES: To assist the endoscopic localization of the lacrimal sac (LS)  relative to nearby landmarks. Methods: This is a descriptive prospective anatomical study. Sixteen lateral nasal walls were dissected endoscopically to identify and localize the LS between October and November 2015. Multiple measurements were obtained from the NS to the anterior and posterior walls of the LS, as well as to the middle turbinate axilla (MTA) and from the MTA to the LS borders. Results: The average distance from the NS to the anterior border of the LS was 42.0 mm and the posterior border was 48.5 mm. The average widths of the LS were 7.55 mm superiorly, and 6.6 mm inferiorly representing a mathematical proof that the LS is a trapezoid shape. The mean distance from the NS to the MTA was 47.3 mm. Nine of the 16 lacrimal sacs (56.3%) were found to be partially overlapped by the MTA. The LS was only totally overlapped and lying posterior to the MTA in one side (6.3%), while in 6 sides (37.5%) the LS lay anterior to the MTA. Conclusion:  Endoscopic surgeons should be aware of the location of the LS relative to nearby landmarks, particularly the MTA. Representing a mathematical proof that the LS is wider at it upper part than lower part best presented as a trapezoid shape. We have provided additional measurements that may prove useful in cases of difficult exposure.
