Objective: To demonstrate and analyze the epidemiological, clinical, and evolutionary data of the association between retinoschisis and primary angle closure suspect (PACS), primary angle closure (PAC), or primary angle closure glaucoma (PACG).

Methods: A retrospective and observational study was conducted at a single ophthalmological medical center, using records from the International Classification of Diseases (ICD-10) for closed-angle glaucoma and retinoschisis. The medical records were analyzed, and all information was recorded.

Results: Out of the 9,854 patients evaluated, 1,144 were classified as having PACS, PAC, or PACG, accounting for 11.6% of the total. Additionally, 123 patients were diagnosed with retinoschisis, representing 1.24% of the cohort. A total of 77 eyes from 58 patients (0.58%) were diagnosed with retinoschisis and PACS, PAC, or PACG. However, 47.1% of patients with retinoschisis had the potential for progression to closed-angle glaucoma. The majority of those patients were female, over 40 years of age, hyperopic, with unilateral involvement and asymptomatic. Regarding the location of retinoschisis, the inferior temporal quadrant was the most affected. The follow-up lasted an average of 5.4 years.

Conclusion: The high percentage of patients with retinoschisis who presented the condition of progression to PACG suggests an association between these pathologies.
