Why it is performed:

It can detect some signs & physiological effects of various circulatory, metabolic and neurological disorders.

Routinely used to assess and diagnose vitro-retinal diseases (such as Diabetic retinopathy, retinal tear and detachment, macular hole, retinal haemorrhage, retinal artery and vein occlusion, choroidal tumor, or macular edema), optic nerve defects, and hereditary diseases.

Fundus examination is used to:

Identify and locate vitro-retinal and optical nerve defects caused by eye diseases or trauma.

Examine the extent of the defects or abnormalities to plan a proper treatment.

Evaluate the success of treatment.

MEDIA OPACITY - PVD – UVEITIS – HYALOID ASTERITIS – IOFB – LENS & IOL DISLOCATIONS

B-scan ultrasound is most useful when direct visualization of intraocular structures is difficult or impossible. Situations that prevent normal examination include lid problems (eg, severe edema, partial or total tarsorrhaphy), keratoprosthesis, corneal opacities (eg, scars, severe edema), hyphema, hypopyon, miosis, pupillary membranes, dense cataracts, or vitreous opacities (eg, hemorrhage, inflammatory debris).

NO MEDIA OPACITY – WHAT FOR?

In such cases, diagnostic B-scan ultrasound can accurately image intraocular structures and give valuable information on the status of the lens, vitreous, retina, choroid, and sclera. However, in many instances, ultrasound is used for diagnostic purposes even though pathology is clinically visible. Such instances include differentiating iris or ciliary body lesions; ruling out ciliary body detachments; and differentiating intraocular tumors, serous versus hemorrhagic choroidal detachments, rhegmatogenous versus exudative retinal detachments, and disc drusen versus papilledema.

VISUAL EVOKED POTENTIAL - VEP

The visually evoked potential (VEP) measures the electrical response of the brain's primary visual cortex to a visual stimulus.

Preemie Eye test (ROP)... how bad is it?

I made the mistake of reading up about the ROP eye test that they are giving my baby early next week. It sounds absolutely terrible. How did your babies do afterwards? The nurses have warned that he may not eat well that day.

Your Baby’s Eye Test

Why your baby needs an eye test

All babies on the neonatal unit are screened for an

eye condition called retinopathy of prematurity

(ROP) if they are born before 32 weeks of

pregnancy or if they weighed 1500 grams or less

at birth.

NO DIABETIC RETINOPATHY WHAT FOR ???NO POSTERIOR POLE CHANGES WHAT FOR ???NO KNOWN ALLERGIES AND THE TWO ABOVE WHAT FOR ???NO CHANGES SO MEDICAL LEGAL ASPECT WHAT FOR ???

THINK ABOUT

CONCENTRATION AND QUANTITY

WAIT ENOUGH TIME OTHERWISE WAIST ALL THE TIME
