Post Test Ilmiah Vitreo Retina

What is the main mechanism of tractional retinal detachment?

• Direct tension on the retina by blood vessels

• Pulling forces from fibroproliferative membranes on the retina

• Accumulation of inflammatory fluid in the retina

• Degeneration of photoreceptor cells

Why is high myopia a risk factor for retinal detachment?

• Subretinal hemorrhage

• Peripheral retinal thinning due to axial elongation

• Protein deposition in the vitreous

• Failure of the blood-retinal barrier

What is a hallmark finding of tractional retinal detachment on ophthalmoscopy?

• Retinal folds

• Small macular tears

• Increased pigmentation in the peripheral retina

• Optic nerve swelling

In exudative retinal detachment, what is the primary cause of subretinal fluid accumulation?

• Retinal tears

• Direct trauma

• Inflammation or vascular leakage

• Optic nerve dysfunction

What is the most common symptom of rhegmatogenous retinal detachment?

• Sharp pain in the eye

• Flashing lights, floaters, and a shadow-like curtain

• Swelling and redness of the eyelids

• Sudden vision loss only at night

Rhegmatogenous retinal detachment frequently starts in the:

• Fovea

• Macula

• Optic disc

• Peripheral retina

The term "retinal break" refers to:

• Separation of RPE from Bruch's membrane

• Partial retinal detachment

• Full-thickness retinal tear

• Incomplete vitreous detachment

Which layer of the retina is firmly attached to the retinal pigment epithelium?

• Ganglion cell layer

• Nerve fiber layer

• Photoreceptor layer

• Inner plexiform layer

Which retinal layer contains the photoreceptors?

• Outer nuclear layer

• Retinal pigment epithelium

• Ganglion cell layer

• Inner nuclear layer

Which structure provides mechanical support to photoreceptor outer segments?

• Müller cells

• Retinal pigment epithelium

• Nerve fiber layer

• Choroid
