Diabetes mellites (DM) is one of the most common systemic disorders in Saudi Arabia and worldwide. Diabetic retinopathy (DR) is a potentially blinding ophthalmic consequence of uncontrolled DM. The early detection of DR leads to an earlier intervention, which might be sight-saving. Our aim in this cross-sectional study is to assess patients’ knowledge and practices regarding DR, and to detect the barriers for eye screening and receiving a check-up from an ophthalmologist. The study included 386 diabetic patients. One hundred and thirty-one patients (33.9%) had T1DM and 188 (48.7%) had T2DM. Most of the diabetic patients (73.3%) know that they must have an eye check-up regardless of their blood sugar level. DM was agreed to affect the retina in 80.3% of the patients, 56% of patients agree that DM complications are always symptomatic, and 84.5% know that DM could affect their eyes. The fact that blindness is a complication of diabetic retinopathy was known by 65% of the diabetic patients. A better knowledge was detected among patients older than 50 years of age (54.9%) compared to those aged less than 35 years (40.9%), which was statistically significant (p = 0.030). Additionally, 61.2% of diabetic patients who were university graduates had a significantly better knowledge in comparison to 33.3% of illiterate patients (p = 0.006). Considering the barriers to not getting one’s eyes screened earlier, a lack of knowledge was reported by 38.3% of the patients, followed by lack of access to eye care (24.4%). In conclusion, there is a remarkable increase in the awareness of DR among the Saudi population. This awareness might lead to an earlier detection and management of DR.

Purpose: To study the effects of perioperative uveitis control (PUC) on postoperative intraocular pressure (IOP) and uveitis activity in uveitic glaucoma (UG) patients who required glaucoma surgeries. Patients and Methods: A retrospective chart review of 109 patients (120 eyes) which had glaucoma surgery for UG. A total of 66 eyes which had PUC were compared to 54 eyes which did not have. Measurements of IOP and uveitis activity were recorded preoperatively and over 2 years postoperatively. Average number of antiglaucoma medications and frequency of surgical failure were obtained in both groups. Results: Over 2 years postoperatively, average IOP was lower in eyes which had PUC. Significant differences in IOP were found at 3 months (P = 0.004), 6 months (P = 0.001), 1 year (P < 0.001), and 2 years (P < 0.001). Lower grades of anterior chamber (AC) inflammation were found in eyes which had PUC. Significant differences were found at 1 month (P < 0.001), 3 months (P < 0.001) and 6 months (P = 0.001). Mean number of antiglaucoma medications at last visit was 0.7 ± 1.1 for eyes which had PUC and 2.6 ± 1.5 for eyes which did not have PUC (P < 0.001). Among eyes which had PUC, only two eyes required second glaucoma surgeries, while 16 eyes with no PUC required further glaucoma surgeries after 27.7 ± 12.5 months (P < 0.001). Conclusion: Proper PUC in patients going for UG surgeries results in lower IOP levels and less AC inflammation over 2 years postoperatively. A comprehensive PUC regimen is needed for uveitic glaucoma patients going for surgeries.

We examined the incidence and natural history of macular retinochoroidal neovascularization (RCN) in enhanced S-cone syndrome (ESCS). Retrospective case series. This single-center study included 14 of 93 patients with ESCS who had signs of active or inactive RCN in ≥1 eye. We conducted multimodal retinal imaging, full-field electroretinography, and molecular genetic analysis of NR2E3 gene. Our main outcome measures included the cumulative incidence of RCN in ESCS, type of RCN, and mode of evolution of RCN. Fourteen (15.1%) of 93 patients with ESCS had RCN in ≥1 eye at 2 to 27 years of age. All 22 RCNs (21 eyes of 14 patients) were macular. Twelve of the RCNs were active with exudates/hemorrhages. Of these, 5 appeared de novo in a subretinal location, with photographic evidence of no pre-existing lesions. The latter were compatible with type 3 neovascularization or retinal angiomatous proliferation and subsequently evolved into unifocal fibrotic nodules. The remaining active lesions all had some degree of pre-existing fibrosis and remained stable. Ten inactive fibrotic nodules, identical to end-stage de novo lesions, were found and were presumed to represent healed RCNs. RCN, a treatable condition, may occur as early as 2 years of age and may be much more common in patients with ESCS than previously estimated. It may be the primary cause of the unifocal submacular fibrosis that is commonly observed in this condition. Additional research is needed to establish the pathogenesis of RCN in patients with ESCS and its optimal management.

PURPOSE: Does perioperative use of Rho-Kinase (ROCK) inhibitors have beneficial effect on corneal endothelial cells after phacoemulsification? SETTING: This study was conducted at King Abdulaziz University Hospital in Riyadh. DESIGN: This was a prospective study assessing the effect of ROCK inhibitors on corneal endothelium after phacoemulsification. METHODOLOGY: Three patients have used ROCK inhibitor 1 day before and 1 week after phacoemulsification surgery, and specular microscopy and Pentacam were done preoperatively and 3 months postoperatively. RESULTS: Endothelial cell density decreased to 11.3%, 9.45%, and 4.09% in eyes with ROCK inhibitors and 23.9% in one eye without ROCK inhibitor. CONCLUSION: Perioperative ROCK inhibitor use has a possible protective effect on corneal endothelium.

Background/Objectives: Brolucizumab is a humanized single-chain antibody fragment with a molecular weight of approximately 26 kilodaltons (scFv, ~26 kDa) targeting all VEGF-A isoforms. Intravitreal brolucizumab (6 mg) is FDA-approved for neovascular age-related macular degeneration (nAMD) (2019) and diabetic macular edema (DME) (2022). We systematically review the literature on brolucizumab for nAMD and DME, focusing on efficacy, safety, pharmacokinetics, real-world outcomes, and cost-effectiveness in adult and pediatric patients. Methods: Our method involves a comprehensive literature search of PubMed, Embase, Scopus, Cochrane, and related databases (through late 2024) using terms including “brolucizumab,” “Beovu,” “neovascular AMD,” “diabetic macular edema,” “safety,” “pharmacokinetics,” and “pediatric.” High-quality clinical trials, meta-analyses, regulatory documents, and real-world studies were prioritized. Results: In pivotal Phase III trials (HAWK/HARRIER for nAMD), brolucizumab 6 mg demonstrated non-inferior visual acuity (VA) gains to aflibercept, with >50% of eyes maintained on 12-week dosing and greater retinal fluid reduction. In DME trials (KESTREL/KITE), brolucizumab was similarly non-inferior to aflibercept for VA and showed superior anatomic drying, with 33–48% of eyes maintained on ≥12-week intervals. However, brolucizumab use has been associated with intraocular inflammation (IOI), retinal vasculitis, and vascular occlusion: clinical trials and post hoc analyses reported higher rates of these events than comparator agents. Real-world cohorts found IOI in ~4–10% of treated eyes, often occurring early (within 3 months) after initiation. Conclusions: In conclusion, Brolucizumab is an effective anti-VEGF option for nAMD and DME, providing durable anatomic control with fewer injections. Non-inferior vision outcomes and superior fluid resolution have been demonstrated. However, it carries a distinct risk of IOI and occlusive vasculitis, necessitating careful patient selection, dosing, and monitoring.

Gene therapy has emerged as a promising treatment for several eye diseases since it may restore vision and stop blindness. Many eye diseases, including retinitis pigmentosa and macular degeneration, have historically been rather difficult to treat and usually cause permanent vision loss. However, thanks to advances in gene therapy, many disorders can now be effectively targeted and genetically changed, providing a safer, more direct, maybe even curative approach. By introducing, altering, or repairing specific genes inside the eye, gene therapy seeks to fix the defective genes causing these disorders, thereby improving general eye health and visual ability. Voretigene neparvovec is one FDA- and EMA-approved treatment for RPE65 mutations. Retinitis pigmentosa, age-related macular degeneration, X-linked retinoschisis, choroideremia, and Stargardt disease are among the several eye disorders still under clinical trials, and experimental treatment is in progress. As research on gene therapy develops, it opens the path for groundbreaking treatments that could fundamentally change the ophthalmic care scene.
