I have my ophthalmology practical exam tomorrow. For that I need, I have a station called as Ophthalmology Instruments, then Perimetry, and also HFA station. So I need a complete review on all the ophthalmic medications used, especially the anti-glaucoma drugs that are used in the treatment of glaucoma and also about the instruments, instruments like chalazionclamp, aireviseration scoop, then corneoscleral scissors, then etc., and two-way irrigation cannula, etc., and many more instruments, and also on systemic and community ophthalmology. Give me a complete and brief in everything, especially the medications I need, the indications, contraindications, the dose, what is the mechanism of action, and which class of drug does the drug belong to, etc.

I have ophthalmology practical exam tomorrow. I need a perfect examination case presentation of cataract surgery patient, pseudophakia, and aphakia, mature senile cataract.
ophthalmology practical exam case presentation pseudophakia aphakia signs slit lamp examination findings IOL inspection
aphakia signs symptoms examination hypermetropia iridodonesis absent red reflex Purkinje images practical ophthalmology
Summary of What's in This Guide
-
Mature Senile Cataract - the full workup including shadow test, absent red reflex, B-scan, IOL calculation, surgical options (phaco vs ECCE vs SICS)
-
Pseudophakia - signs of IOL in situ, posterior capsule assessment, PCO, YAG capsulotomy, complications
-
Aphakia - iridodonesis, brilliant red reflex, deep AC, 2 Purkinje images, limbal scar + PI, aphakic correction (+10-12D), Jack-in-the-box phenomenon
-
Cataract types - PSC vs Nuclear vs Cortical vs mature/hypermature/Morgagnian with distinguishing features
The 3 Most Exam-Critical Points to Memorize Right Now
| Sign | Mature Cataract | Pseudophakia | Aphakia |
|---|---|---|---|
| Red reflex | ABSENT | Bright/normal | BRILLIANT (enhanced) |
| Shadow test | NEGATIVE (absent) | N/A | N/A |
| Iridodonesis | Absent | Absent | PRESENT |
