Correct Answer - B
B i.e. Central Retinal Artery Occlusion

Central retinal artery occlusion characteristically presents with
sudden painless loss of vision, cherry red spot & cattle-truck
appearanceQ (of retinal veins usually).

Source of emboli from carotid artery & heart disease, and thrombus from arteriosclerosis along with hypertension & arteritis are predisposing factors.

Correct Answer - D
Ans. is 'd' i.e., All the above

Fuch's heterochromic iridocyclitis (Fuch's uveitis syndrome)

It is a form of anterior and intermediate uveitis.

The condition is usually unilateral and chronic in nature and is
characterized by a chronic non-granulomatous uveitis and eventually results in iris heterochromia (a change in the colour of iris).


The disease has following characteristic features :
i) Heterochromia of iris
ii) Diffuse stromal iris atrophy
iii) Fine KPs at back of cornea
iv) Faint aqueous flare
v) Absence of posterior synechiae
vi) A fairly common rubeosis iridis, sometimes associated with
neovascularisation of the angle of anterior chamber.
vii) Comparatively early development of complicated cataract and secondary glaucoma (usually open angle type). Glaucoma has been reported in 10-59% of cases.


Treatment
Fuch's heterchromic uveitis responds variable to steroids and
cycloplegics.

The complications of long term use of these drugs may at times outweigh their potential benefits.

Therefore, treatment withtopical steroids is given to iritis which is sufficiently active to require
the treatment, otherwise the patient is routinely followed without
giving any treatment.

Cataract responds well to most forms of intraocular surgeries,
including the standard IOL implantation.

Hyphemia may occur
because of rubeosis iridis (neovascularization of iris).

Glaucoma control may be somewhat more problematic, with surgical options indicated for later forms of disease

Correct Answer - D
Ans. D: Anterior dislocation of the lens

Factors responsible for hypermetropia:

Short axial length of the eyeball

Curvature hypermetropia commonly occurs as a factor in astigmatism (corneal plana)

Index hypermetropia accounts for the hypermetropia of old age due
to increased refractive index of the cortex of the lens relative to the
nucleus so that overall refractive power of the lens decreases.

It may be associated with diabetes, tumors, microphthalmia (a growth dysfunction during fetus development) and fovea hypoplasia, a condition that affects the blood vessels in the retina.
While these conditions may result in hypermetropia, one of the most
commonly cited causes of farsightedness is considered to be aging.
