A 25 years old professional basketball player presents with blurry vision in his right eye. No previous trauma history. Visual examination reveals 20/80 vision in that eye on best-corrected refraction and slit-lamp examination finds iridodonesis and phacodonesis. On dilated examination find a lens dislocated superotemporally. Which of the following systemic disease is most likely related to this case?

• Weill-Marchesani syndrome

• Homocystinuria

• Peter's anomaly syndrome

• Marfan's syndrome

A 66 years old woman come with chief complain pain eye with vomitus. This patient presents with the congestive eye and mature lens. The intra ocular pressure is 67 mmHg, without evidence of pupillary block. What is the most likely diagnosis ?

• Phacomorphic glaucoma

• Phacolityc glaucoma

• Phacoantigenic glaucoma

• Lens particle glaucoma

What is the correct statement regarding the degenerative cataract

• They occur earlier in a men than women

• They interfere with the vision only after patients are older than 75 years old

• They are more likely nuclear than cortical

• The incidency of nuclear cataract is higher in subtropic area rather than tropical area

What is the true statement about cataract?

• Cataract is the first cause of irreversible blindness in the world

• Free radical is one of the risk factor of cataract

• Medicamentosa is the best treatment of cataract

• Phacoemulsification surgery is the only treatment of cataract

What clinical feature would confirm your suspicion that a patient has a traumatically dislocated or subluxated crystalline lens?

• Phacodenesis

• Aquous misdirection

• Reduce refractive astigmatism

• Phacomorphic Glaucoma

A 60 years old female with cataract complicate undergo cataract surgery with implantation IOL. One year after surgery she complain decreases in visual acuity without any other symptom. What is the most possible caused of her complain?

• Uveitis

• Posterior capsule opacification

• Myopia refractive

• Proliferative diabetic retinopathy

What occurs when the cilliary muscle contracts?

• The diameter of the muscle ring is increased, thereby increasing tension on the zonular fibers, allowing the lens to become more spherical

• The diameter of the muscle ring is reduced, thereby increasing tension on the zonular fibers, allowing the lens to become more spherical

• The diameter of the muscle ring is increased, thereby relaxing tension on the zonular fibers, allowing the lens to become more spherical

• The diameter of the muscle ring is reduced, thereby relaxing tension on the zonular fibers, allowing the lens to become more spherical

Which of the following is not a function of the crystalline lens?

• Maintaining clarity

• Providing accommodation

• Metabolizing toxins

• Refracting light

When comparing sub-Tenon’s anesthesia to retrobulbar anesthesia for ocular surgery, what is the most advantageous characteristic for sub-Tenon’s anesthesia?

• Anterior segment anesthesia better than posterior segment anesthesia

• Lower risk of penetrating injury

• Better for ocular re-operation

• More complete akinesia

The Endophthalmitis Vitrectomy Study (EVS) showed which one of the following?

• If the vision is hand motion or better, vitreous tap should be performed with intraocular injection of antibiotics

• Systemic antibiotics demonstrate a significant benefit

• If the vision is worse or equal to light perception, vitrectomy is of no value even with injection of antibiotics

• Post operative topical corticosteroid drops reduce rates of endophthalmitis
