Oculoplasty Practice Questions

Q: A patient presents with itching in eyes with redness of eyelids. What is correct about the image shown below? (Recent NEET Pattern 2016-17)

Blepharitis. ***Blepharitis*** - The image shows **redness** and **inflammation of the eyelid margins**, often accompanied by scales or crusts at the base of the eyelashes. This is characteristic of blepharitis. - The history of **itching** and **redness of eyelids** further supports the diagnosis, as these are common symptoms of blepharitis, an immune-mediated inflammation. *Trichiasis* - This condition involves **misdirected eyelashes** that grow inwards and rub against the surface of the eye. - While it can cause irritation, the primary feature in the image is inflammation and crusting of the eyelid margin, not just misdirected lashes. *Blepharospasm* - **Blepharospasm** is an involuntary, repetitive, bilateral twitching or forceful closure of the eyelids. - This is a neurological condition affecting eyelid movement and is not depicted by the visible inflammation in the image. *Distichiasis* - **Distichiasis** is a rare condition where there is an extra row of eyelashes growing from the meibomian gland openings on the eyelid margin. - The image does not show an extra row of lashes; instead, it indicates inflammation and debris along the existing lash line.

Q: What is shown in the image given below?

Ectropion. ***Ectropion*** - The image clearly displays the **sagging and outward turning of the lower eyelid**, exposing the conjunctiva. - This eversion of the eyelid margin is the hallmark clinical presentation of **ectropion**. *Chalazion* - A chalazion appears as a **firm, non-tender nodule** within the eyelid, usually due to a blocked meibomian gland. - It would not typically involve the entire eyelid margin turning outwards. *Stye* - A stye (hordeolum) is an **acute, painful, localized infection** of an eyelid gland, often appearing as a red, tender bump on the eyelid. - Unlike ectropion, it's an inflammatory lump, not an eversion of the lid margin. *Entropion* - Entropion is the **inward turning of the eyelid margin**, causing the lashes to rub against the cornea. - This is the opposite of what is seen in the image, where the eyelid is turned outwards.

Q: A 30-year-old woman presents with painful eye swelling. Based on the clinical photograph shown, the most likely diagnosis is:

Acute dacryocystitis. ***Acute dacryocystitis*** - The image shows a **painful, erythematous, and swollen area** at the medial canthus below the **medial palpebral ligament**, characteristic of acute inflammation of the lacrimal sac. - This condition results from **obstruction of the nasolacrimal duct**, leading to bacterial infection and abscess formation in the lacrimal sac. *Lacrimal gland carcinoma* - This condition typically presents as a **slow-growing mass** in the upper outer quadrant of the orbit, often causing **proptosis and displacement** of the globe, rather than acute inflammation at the medial canthus. - While it can be painful, the **acute inflammatory signs** and specific location seen in the image are not typical of lacrimal gland carcinoma. *Orbital cellulitis* - Orbital cellulitis involves inflammation and infection of the **orbital tissues posterior to the orbital septum**, causing generalized swelling of the eyelids, proptosis, pain with eye movements, and potentially vision loss. - The localized swelling near the medial canthus with obvious inflammatory signs is more consistent with a dacryocystitis, whereas orbital cellulitis would involve a broader area of swelling and often more systemic symptoms. *Hordeolum externum* - A hordeolum externum, or stye, is an acute **localized infection of a hair follicle or sebaceous gland** (gland of Zeis or Moll) along the eyelid margin. - The swelling seen in the image is much larger and more medially located, involving the lacrimal sac area, rather than being confined to the eyelid margin.

Q: What does the following image show?

Xanthelasma. ***Xanthelasma*** - The image shows a **yellowish, raised plaque** on the inner part of the lower eyelid, which is characteristic of **xanthelasma**. - **Xanthelasma palpebrarum** is a common cutaneous manifestation of **lipid deposition**, often associated with **dyslipidemia**. *Stye* - A stye (hordeolum) is an **acute bacterial infection** of an eyelash follicle or a meibomian gland, presenting as a **red, painful, tender bump** on the eyelid margin. - Unlike the image, a stye is typically **inflamed and painful**, and appears as a localized pustule. *Chalazion* - A chalazion is a **painless, firm nodule** resulting from a clogged meibomian gland, often developing after a stye. - While it's a lump, it is typically **deeper within the eyelid tissue** and not yellowish or plaque-like on the surface. *Blepharitis* - Blepharitis is a **chronic inflammation of the eyelid margins**, often presenting with **redness, scaling, crusting**, and itching of the eyelashes. - It does not present as a distinct, raised, yellowish plaque like the one shown in the image.

Q: All are true about the lesion shown except:

Contains cheesy sebaceous material. ***Contains cheesy sebaceous material*** - The image shows a **hordeolum (stye)**, which is an acute, purulent infection of the eyelid glands, typically presenting as a red, painful bump. - A hordeolum contains **pus** (neutrophils, bacteria, cellular debris), not cheesy sebaceous material. Cheesy sebaceous material is characteristic of a **chalazion**, which is a chronic lipogranulomatous inflammation of the Meibomian glands, often developing after a hordeolum resolves. *Suppurative inflammation of glands of Zeis* - An **external hordeolum** (stye) is caused by acute **suppurative inflammation** of the glands of Zeis or Moll (sebaceous and apocrine glands, respectively) located at the base of the eyelashes. - The image depicts an external hordeolum, consistent with this pathology. *Caused by Staphylococcus aureus* - The most common causative organism for both external and internal hordeola (as well as most acute bacterial infections of the eyelid) is **Staphylococcus aureus**. - This bacterium is a common inhabitant of the skin and can opportunistically infect blocked glands. *Can lead to cavernous sinus thrombosis* - Although rare, severe facial infections, including those around the eye such as a hordeolum, can potentially spread through the facial venous system (which lacks valves) to the **cavernous sinus**. - This can lead to serious complications like **cavernous sinus thrombosis**, although it is an infrequent outcome of uncomplicated hordeola.

Q: All are used for the treatment of the condition shown below except:

Canthoplasty. ***Canthoplasty*** - The image depicts **trichiasis**, a condition where eyelashes grow inwards and rub against the cornea. Canthoplasty is a surgical procedure that **modifies the outer or inner canthus of the eye** (the corners) and is not primarily used to address misdirected eyelashes. - Canthoplasty is typically performed for conditions like **ectropion** or **entropion** to correct eyelid position, or for cosmetic purposes, not for direct removal or redirection of individual eyelashes. *Electrolysis* - **Electrolysis** is a common and effective method for treating trichiasis by destroying the hair follicle with an electric current, preventing regrowth. - This procedure targets individual misdirected eyelashes, providing a long-term solution. *Electrodiathermy* - **Electrodiathermy** (also known as diathermy) uses high-frequency electrical currents to generate heat, which can be applied to destroy hair follicles, similar to electrolysis. - It is an effective treatment for permanent removal of eyelashes in cases of trichiasis. *Cryotherapy* - **Cryotherapy** involves freezing the eyelash follicles to destroy them, preventing further abnormal growth. - This technique is another viable option for the permanent removal of eyelashes in trichiasis and can be applied to a group of misdirected lashes.

Q: What does the following image show?

Entropion. ***Entropion*** - This image clearly depicts the **lower eyelid rolling inward towards the eye**, causing the eyelashes to rub against the cornea. - This inward turning is the defining characteristic of **entropion**, leading to irritation, pain, and potentially corneal damage. *Distichiasis* - **Distichiasis** is the presence of a double row of eyelashes, with the accessory row arising from the meibomian gland orifices. - The image shows a single, albeit inwardly directed, row of eyelashes, not an extra row. *Ectropion* - **Ectropion** is the opposite of entropion, where the eyelid turns **outward**, exposing the inner surface of the lid. - The image explicitly shows the eyelid turning *inward*, ruling out ectropion. *Normal eyelids* - **Normal eyelids** should properly cover and protect the eye, with the eyelashes directed outward, away from the corneal surface. - The depicted eyelid is clearly abnormal due to its inward rotation and irritation, indicating a pathological condition.

Q: What does the following image show?

Euryblepharon. ***Euryblepharon*** - The image shows an **enlarged palpebral fissure** and **vertical laxity of the eyelids**, consistent with euryblepharon. - This condition can lead to exposure keratopathy and tearing due to poor eyelid closure. *Coloboma* - A coloboma is a congenital defect where part of the eye structure (like the iris, retina, or eyelid) is **missing or malformed**. - It would typically appear as a **notch or gap** in the affected tissue, which is not depicted in this image. *Floppy eyelid syndrome* - Characterized by **loose, easily everted upper eyelids**, often occurring in obese males. - While there is eyelid laxity in the image, the primary feature here is the widened palpebral fissure and not easily everted eyelids. *Iridodialysis* - Iridodialysis is a **disinsertion of the iris root from the ciliary body**, often caused by trauma. - It would present as a **D-shaped pupil** with an area where the iris is detached, which is not seen here.

Q: What does the following image show?

Epicanthus. ***Epicanthus*** - The image shows an **epicanthal fold**, which is a fold of skin that covers the inner corner (medial canthus) of the eye, giving the appearance of a wider set of eyes. - This is a normal anatomical variation, especially common in individuals of East Asian descent and infants, but can also be a feature in certain genetic conditions like **Down syndrome**. *Telecanthus* - **Telecanthus** refers to an abnormally increased distance between the inner corners (medial canthi) of the eyes, while the interpupillary distance (distance between pupils) remains normal. - The image does not clearly depict an increased distance between the medial canthi that falls outside normal variation. *Ablepharon* - **Ablepharon** is an extremely rare congenital anomaly characterized by the partial or complete absence of eyelids. - The image clearly shows the presence of eyelids, ruling out ablepharon. *Epiblepharon* - **Epiblepharon** is a congenital condition where a fold of skin and muscle overrides the margin of the eyelid, causing the eyelashes to turn vertically or inward towards the globe, often leading to corneal irritation. - While it involves an extra fold of skin, it specifically affects the eyelid margin and eyelashes, which is distinct from the more generalized epicanthal fold seen in the image.

Q: A 10-year-old girl child presents with ptosis of right eyelid. On movement of jaw there is retraction of ptotic eyelid. The image of the patient is shown below. This condition is known as:

Marcus Gunn syndrome. ***Marcus Gunn syndrome*** - This syndrome, also known as the **Marcus Gunn jaw-winking phenomenon**, is characterized by a unilateral congenital ptosis that retracts or elevates when the jaw is moved (e.g., chewing, sucking, jaw protrusion). - The image clearly shows **ptosis of the right eyelid** (Image A) and **retraction of the ptotic eyelid** when the mouth is open (jaw movement, Image B), which is the hallmark of this condition. *Marcus Gunn pupil* - This refers to an **afferent pupillary defect (APD)**, typically detected by the swinging flashlight test, where the pupil paradoxically dilates when light is shined into the affected eye. - It is a sign of **optic nerve damage** and is unrelated to eyelid ptosis or jaw movements affecting the eyelid. *Floppy eyelid syndrome* - This condition is characterized by **loose, elastic upper eyelids** that evert easily, often during sleep, and are associated with chronic papillary conjunctivitis. - It is commonly seen in **obese, middle-aged men** and does not involve jaw-winking phenomena or congenital ptosis. *Myasthenia gravis* - This is an **autoimmune neuromuscular disorder** causing fluctuating weakness of voluntary muscles, including the extraocular muscles and those responsible for eyelid elevation. - While it can cause **ptosis** and **diplopia**, the ptosis typically worsens with fatigue and does not exhibit the specific jaw-winking phenomenon.
