Pictionary of eye

Parthopratim Dutta Majumder

Pitionary of eye is perhaps the perfect example of learning with fun. You remember a daily-life object or event and learn to corelate with ophthalology. I have extensively searched the text-books, literature and compiled this list . If you have something new such key words, kindly pass it on to me.

 

redeyeSwiss cheese appearance

Swiss cheese is a cheese from Switzerland, often termed as emmental or emmentaler, is a yellow, medium-hard cheese, with characteristic large holes. Few bacterias are used for the production of these cheeses. In the late stage of cheese production, there is release of carbon dioxide gas, which slowly forms the bubbles that make holes.

SwisscheeseIn ophthalmology, the word, swiss cheese is used to describe a variety of lesions. In Band Keratopathy, small lucid areas are noted in the opacity, representing regions where corneal nerves penetrate Bowman's layer. This characteristic picture of band keratopathy is described as “swiss cheese” appearance. Also in resolving stages of acute retinal necrosis, retinal pigment epithelium perturbation develops with areas of clearing in fundus  which form a characteristics “Swiss- cheese appearance”.

 

redeyePizza pie appearance

Pizza is a world-popular dish of Italian origin. The term pizza pie is dialectal, and pie is used for simPizzaplicity in some contexts, such as among pizzeria staff.

In ophthalmology this word is used to describe the typical lesions of cytomegalovirus retinitis which resembles a pizza pie with an admixture of white (retinal inflammation) and red (hemorrhage) colors . The juxtaposition of large zones of whitish, granular necrosis, next to red retinal hemorrhage has led this presentation of CMV retinitis to be called either "pizza-pie" or "cheese and ketchup."

 

redeyeSalt and Saltpepper appearance:

The combination of salt and pepper can be found in every dining table. The tradition of using this combination was originated from 17th century French cuisine.

In ophthalmology the word “salt and pepper" is used to denote fundus picture. For example,  fundus picture of congenital rubella, in which focal patches of retinal pigment epithelial hypopigmentation (salt) alternate with hyperpigmentation (pepper)is seen.

 

 

redeyeTomato Ketchup appearance:

Ketchup is used as  a general term for sauce. In Sturge-Weber syndrome, diffuse choroidal hemangioma appears as a broad red-range thickening of the posterior choroid. The tumor appears more red than the background fundus, a finding sometimes called the "tomato ketchup" fundus.

 

redeyeScrambled egg appearance:

The solid yellow egg yolk macular lesion is neither common in vitelliform macular dystrophy/ Best's disease nor is it pathognomonic for this disorder. When it does occur the patient is usually asymptomatic with 6/6 vision. When this egg yolk "ruptures" the vision will then diminish. The appearance of the "scrambled egg"  or "pseudohypopyon" maculopathy is well recognized.

 

redeyePort-wine stain:

The hallmark of Sturge-Weber syndrome is the nevus flammeus or port-wine stain which is found in the distribution of first, first and second, or first, second and third divisions of the trigeminal nerve. It is most often unilateral and respects the midline. It is present at birth and sometimes darkens with age. Histologically, the nevus flammeus is a cavernous hemangioma.

 

redeyeCracked Mud appearance:

 

In end-stage Progressive Outer Retinal Necrosis (PORN), dense white, plaque-like scarring with retinal atrophy occurs which is described as “cracked-mud" appearance.

 

redeyeSunset glow appearance:

 

The convalescent or recovery or chronic stage of Vogt-Kayanagi-Harada is characterized by pale fundus which is described as sunset-glow fundus.

 

redeyeHeadlight-in-a-fog appearance:

 

In toxoplasmosis the acute lesions are elevated with indistinct hyperpigmented borders and most often are located in the posterior pole. Ophthalmoscopy is frequently obscured by a dense vitreous exudateor haze, giving the classic "headlight-in-a-fog" appearance.

 

redeyeCandle wax drippings:

 

Yellow-white, waxy retinal exudates that appear to stream along retinal veins are seen in sarcoidosis. These are known as candle wax drippings and are often found in the inferior equatorial retina and occasionally in the posterior pole.

redeyeBread crumbappearance:

Bread crumbs are small particles of dry bread, which are used for breading or crumbing foods. Granular corneal dystrophy shows discrete stromal opacities with the appearance of snow-flakes or bread crumbs.

 

redeyeTobacco dust:

 

Pigmented cells in the vitreous seen in retinal detachments are often described as tobacco dust.

 

redeyeCartwheel appearance:

 

The foveal schisis characteristically creates a cartwheel pattern formed by folds in the internal limiting membrane overlying microcyst within the nerve fiber layer.

 

redeyeBag of Worm appearance:

 

Plexiform neurofibroma consists of a proliferation within a nerve sheath, which produces a markedly thickened, tortuous nerve. On palpation, it has been described as resembling a bag of worms.

 

redeyeChampagne cork:

 

In the late stages of papilloedema, the optic disc takes the appearance of the dome of a champagne cork

 

redeyeMutton Fat:

 

Large greasy-appearing aggregates of inflammatory cells on the corneal endothelium, typically seen in Granulomatous uveitis are termed as “Mutton Fat” Keratic precipitates. Now tell me what condition is referred to as "chicken fat" appearance ? Well the term is not that ocular
