Sample OMSB Ophthalmology (OEOPTH) Practice Questions
Try these sample questions to review concepts for the OMSB Ophthalmology (OEOPTH) exam. Each question includes a detailed explanation. Start the interactive quiz above for the full 100+ question experience with AI tutoring.
1An elderly patient undergoing cataract surgery has an axial length of 21.20 mm measured by optical biometry. Which intraocular lens (IOL) calculation formula is traditionally considered most accurate for this short eye?
2During phacoemulsification of a dense nuclear cataract, the surgeon notes a tear in the posterior capsule while removing the final quadrant. The anterior hyaloid face remains intact. What is the most appropriate immediate surgical step?
3A 68-year-old patient presents on the first postoperative morning following uncomplicated cataract extraction with diffuse limbus-to-limbus corneal edema, marked anterior chamber fibrinous reaction with hypopyon, and mild discomfort but no pain. B-scan ultrasound demonstrates a clear vitreous cavity. What clinical diagnosis is most consistent with these findings?
4A 72-year-old male with benign prostatic hyperplasia presents for cataract surgery. Preoperatively, the surgeon reviews his medications and notes tamsulosin. Which intraoperative triad defines the syndrome associated with this medication?
5Following uncomplicated implantation of a toric intraocular lens (IOL), postoperative refraction reveals residual astigmatism. Approximately what percentage of the cylinder-correcting power of a toric IOL is lost for every degree of rotational misalignment from its intended axis?
6Which organism is identified as the most frequent causative agent of acute postoperative bacterial endophthalmitis following cataract extraction?
7A patient presents 4 days after cataract surgery with intense pain, ciliary injection, hypopyon, and visual acuity reduced to light perception (LP). Based on the definitive findings of the Endophthalmitis Vitrectomy Study (EVS), which management strategy is indicated?
8During evaluation of a 55-year-old patient with reduced vision, slit-lamp examination reveals a well-demarcated dense white disk-shaped opacity adhered to the central posterior lens capsule. Which surgical precaution is most critical during phacoemulsification of this posterior polar cataract?
9When converting an intended in-the-bag posterior chamber intraocular lens (IOL) implantation to ciliary sulcus placement because of an anterior capsular tear with an intact posterior capsule, how should the calculated lens power typically be adjusted for a mid-range dioptric power (e.g., +18.0 to +25.0 D)?
10A 62-year-old patient who underwent cataract surgery 8 months ago presents with intermittent blurred vision, red eye, elevated IOP of 34 mmHg, and microhyphema. Slit-lamp biomicroscopy reveals iris transillumination defects corresponding to the haptic of a single-piece acrylic IOL placed in the ciliary sulcus. What is the fundamental pathophysiology of this condition?
About the OMSB Ophthalmology (OEOPTH) Exam
The Omani Examination for Ophthalmology (OEOPTH) is the Oman Medical Specialty Board occupational classification examination conducted for ophthalmology candidates applying for employment in local healthcare institutions in Oman.
