Egyptian Board Ophthalmology - independent subject foundations common mistakes
Egyptian Board Ophthalmology - independent subject foundations · Understand the traps and how to avoid them.
Getting prism magnitude right but direction wrong
Plus and minus lenses have different prism-base relationships to their centers.
What to do instead
Draw the gaze point and optical center, then determine base direction separately from magnitude.
Using one thickness as proof of refractive-surgery safety
Tomography, progression, tissue relationships and other factors also matter.
What to do instead
Assess the actual eye and the complete relevant risk framework.
Treating every corneal ulcer with the same sampling rule
Size, site, atypical findings and tissue threat change investigation needs.
What to do instead
Use the actual severity and avoid delaying appropriate urgent treatment.
Excluding aneurysm solely because the pupil is spared
Acquired third-nerve palsy can require imaging despite this feature.
What to do instead
Use the complete presentation and appropriate neurovascular assessment.
Excluding infection from postoperative timing alone
Typical timing ranges overlap and cannot replace examination.
What to do instead
Assess vision, pain, vitreous involvement and the clinical trajectory.
Diagnosing glaucoma from pressure alone
Damage can occur at apparently normal pressures and hypertension can exist without damage.
What to do instead
Integrate structure, function, pressure and angle findings.
Banning every uveal melanoma biopsy
Selected specialist sampling can contribute to diagnosis or prognostication.
What to do instead
Distinguish tumor type and investigation purpose within specialist care.
Assuming optic-disc drusen exclude raised pressure
Drusen and another cause of disc swelling can coexist.
What to do instead
Interpret imaging, symptoms and the complete neurological and ocular assessment.
