Clinical analysis of secondary glaucoma in Central China

Introduction: We aimed to investigate the incidence and prognosis of retinal injury in patients with lens dislocation caused by blunt eye trauma.Methods: We retrospectively analyzed 53 patients who underwent lensectomy and vitrectomy for contusive lens dislocation and had no preoperative retinal injuries. Patients were categorized according to the presence of retinal injury discovered intraoperatively. The clinical features of 53 eyes were assessed during a 3‐month postoperative follow‐up.Results: Retinal injuries were observed intraoperatively in 28 patients (52.8%), predominantly in peripheral regions, with a single retinal tear being the most common type. Total lens dislocation was more frequent than subluxation in the group with retinal injuries. The intraocular pressure (IOP) at the 3‐month follow‐up was significantly lower than the initial IOP in both groups, with no significant differences between them. The corrected distance visual acuity (CDVA) significantly improved in both groups without significant differences.Conclusion: Half of the patients without preoperative retinal injuries were found to have injuries during surgery. Total lens dislocation carried a greater risk of retinal injuries than subluxation. The improvement in CDVA after prompt retinal injury treatment did not significantly differ from that in patients without retinal injury, highlighting the importance of prompt intervention.

Purpose To determine the prevalence and types of secondary glaucoma in adult patients in the Mexican population. Methods Observational, cross-sectional, descriptive and retrospective study in Patients over 18 years of age diagnosed with secondary glaucoma in the period from January-June 2024. A non-probabilistic sampling was carried out within the established period, selecting patients with secondary glaucoma. The analysis included descriptive statistics of central tendency (mean, median, and mode) and dispersion (range, standard deviation) for numerical variables, as well as tables and/or graphs for categorical variables. Results A total of 2390 records were analyzed, of which 987 corresponded to subsequent patients, a final sample of 1403 first-time patients were obtained, of which 208 corresponded to secondary glaucoma (14.83%). The most frequent cause of secondary glaucoma was secondary to neovascularization (n = 79, 37.98%), in order of frequency, intraocular surgery (n = 40, 19.23%), corneal transplant (n = 26, 12.50%), ocular inflammation (n = 21, 10.10%), pseudoexfoliation syndrome (n = 18, 8.65%), ocular trauma (n = 9, 4.33%), pathologies associated with the lens (n = 7, 3.37%), other causes (n = 3, 1.44%), pigment dispersion syndrome and associated with corticosteroids (n = 2 each, 0.96%), finally associated with tumors (n = 1, 0.48%). Conclusion The prevalence of secondary glaucoma in adult patients of the Mexican population was 14.8% (n = 208). The prevalence was 50% in women and 50% in men (n = 104). The most common type was secondary to neovascularization in both sexes, the most frequent age was found in patients between 50 and 59 years.
