Purpose: To describe a novel surgical technique for external drainage of choroidal detachment/suprachoroidal hemorrhage with a butterfly needle. Materials and Methods: This is a retrospective case series on six eyes with serous and/or hemorrhagic choroidal detachments due to previous intraocular surgery or perforating ocular trauma that underwent active external suprachoroidal fluid drainage procedure with butterfly needle. The primary outcome measures were perioperative controlled fluid discharge and presence of choroidal detachment at 1 week, 1 month, and 6 months postoperatively. Secondary outcome measures were postoperative visual acuity and intraocular pressure. Results: During drainage, controlled hemorrhage discharge was observed. Drainage resolved hemorrhagic choroidal detachments at 1 week postoperatively. Intraocular pressure significantly increased, and visual acuity improved in all eyes. No complications were noted. Conclusion: Management of hemorrhagic choroidal detachment is challenging, and external drainage can be complicated. Active aspiration of hemorrhagic material with a butterfly needle may help early resolution.

The aim of this study is to characterize the sociodemographic, epidemiological, and clinical characteristics of ocular injuries in a secondary-level public hospital in Türkiye, identify the risk factors in the region, raise awareness on this issue, and propose solutions for injury prevention. This hospital-based retrospective cross-sectional study was conducted using data from patients who were followed up and treated for ocular trauma between January 2021 and January 2023 in a secondary-level public hospital located in the Middle Black Sea region of Türkiye. All patients, regardless of age, diagnosed with eyeball, eyelid, and orbital trauma were included. The age and gender of the patients, the situation or object that caused the injury, the location where the injury occurred, the type of injury according to the Birmingham Eye Trauma Terminology System (BETTS), initial and final visual acuities, and treatment outcomes were analyzed. Medical records of 83 patients aged between two and 93 years were evaluated. Ocular trauma predominantly occurred in individuals aged 18 to 35 years (35%), with males comprising the majority (74.6%). Closed globe injury was the most common type of injury (73.5%), while injuries without globe involvement accounted for 18.1%, and open globe injuries comprised 8.4%. The most common cause of ocular injuries was falling (22.9%), with 47.3% of the patients in this group being 60 years of age or older. The most frequently implicated object in open globe injuries was wood, accounting for 42.8%. It was observed that injuries occurred most frequently on the streets (38.6%), followed by incidents at home (31.3%) and in the workplace (22.8%). Perforating injuries and ruptures were associated with the worst prognosis for final outcome. Falls in older adults were the most common cause of trauma. Preventive measures should be implemented to address the causes and risk factors of fall-related eye injuries in the elderly. Raising awareness among society and authorities about the causes and consequences of eye injuries is essential. By doing so, these injuries can be effectively prevented.

Background and Objectives: To evaluate the magnitude, axis and age-related changes in corneal astigmatism in patients before cataract surgery. Materials and Methods: In this retrospective, cross-sectional, and observational study, data from 2152 eyes that underwent phacoemulsification were evaluated. Keratometric values were obtained using the IOL Master 500 device. The frequency, magnitude and axis of corneal astigmatism were determined. The astigmatism axis was categorized as with the rule (WTR), against the rule (ATR), and oblique astigmatism. Quantitative analysis was performed using the power vector method (J0 and J45). The distribution and characteristics of corneal astigmatism data according to age were analyzed. Results: The mean age of the patients was 70.56 ± 8.88 years (range 40–94 years) and 1010 (46.9%) were males. Mean corneal astigmatism, J0 and J45 values were 0.96 ± 0.72, 0.05 ± 0.51, 0.01 ± 0.30 diopters (D), respectively. The most common range of magnitudes was 0.50–0.99 D with 38.8%, followed by <0.50 D (25.3%), 1.00–1.49 D (20.3%), and 1.50–1.99 D (8.7%). The cubic regression curve showed a U-shaped nonlinear relationship between age and corneal astigmatism (p < 0.001). The most common type of astigmatism was WTR with 43.4%, followed by ATR with 37.5% and oblique astigmatism with 19.1%. With the increase in age, the astigmatism axis gradually changed from WTR to ATR. There was a linear trend in the rate of these types of astigmatism across age groups (p < 0.05). Additionally, in patients under 65 years of age, WTR astigmatism was negatively correlated with age, while in patients 65 years of age and older, ATR astigmatism was positively correlated with age (r = −0.217, p < 0.001; r = 0.153, p < 0.001, respectively). Linear regression analyses revealed that the J0 value decreased significantly with age, whereas J45 showed no significant relationship. Specifically, J0 decreased by 0.014 D per year of age (95% confidence interval [CI], 0.011–0.016; p < 0.001). Conclusions: The results obtained in this study may provide information to guide surgeons in the management of astigmatism and the choice of toric intraocular lens in cataract surgery.
