In hyperparathurodism

Calcium may precipitate in cornea

called = Band keratopathy

ophthalmology spot diagnosis - MIM  BandK


ophthalmology spot diagnosis - MIM  Dur10518_fm-1


ophthalmology spot diagnosis - MIM  Smile

ophthalmology spot diagnosis - MIM  Bk2b




Clinical features:
Symptoms:
Decrease visual acuity as the deposits become white and dense
Painful
Signs:
Interpalpebral deposition of calcium phosphate salts in the
subepithelial and anterior stroma with clear areas separating it from
the limbus
Clear areas and small circular areas where nerve endings perforate
the Bowman's layer are seen within the band and give it a "Swiss
cheese" appearance

Identifiable causes:
dry eye syndrome, chronic exposure keratopathy, chronic ocular
inflammation such as uveitis, phthisis bulbi, old interstitial
keratitis, long standing
glaucoma and repeated trauma such as multiple ocular surgeries.

Systemic conditions that cause increased serum calcium or phosphorus levels such as multiple myeloma, [/size]Band keratopathy developed in a silicone oil-filled eye. hyperparathyroidism, sarcoidosis, ****static disease and chronic renal failure may all lead to the formation of band keratopathy.

Association with chronic exposure to chemical irritants such as
prolonged use of pilocarpine that contain mercurial preservatives or
intraocular substances, including silicone oil for retinal detachment
repair are also noted.

Management:
Treatment is indicated for loss of visual acuity, intolerable eye irritation or
cosmesis.
Repeated application of
calcium binding agent EDTA (ethylenediaminetetraacetic acid) and scraping of the corneal surface after removing the epithelium is usually effective to treat relatively mild cases.
Excimer laser phototherapeutic keratectomy[size=12] has been effectively performed
to treat more extensive cases.

Subconjunctival Hemorrhage

ophthalmology spot diagnosis - MIM  Conjhemb


May occur spontaneously following minor trauma such as rubbing of the eyelid

or as a result of ocular injuries,

infections,

venous congestion,

hypertension,

vascular fragility

or other systemic conditions related to impaired blood coagulation.



Symptoms:

usually asymptomatic.



Management:

In the setting of trauma, the underlying structures must be carefully assessed to rule out possible penetrating injury.

Therapy is usually supportive using ice packs to minimize tissue
swelling and stop the bleeding in the acute phase, and for relief of
discomfort

Conjunctival Laceration



ophthalmology spot diagnosis - MIM  Conjlacerationb


Clinical features:

May be isolated or part of more severe intraocular injuries.



Symptoms:

ocular irritation, pain and foreign body sensation.
Signs include chemosis, subconjunctival hemorrhage and torn conjunctiva.



diagnosis

Thorough eye examination under topical or general anesthesia
includes dilated fundus examination to rule out intraocular foreign
body.

Seidel test to rule out open globe injury

Ultrasonography.

CT scan to rule out intraocular foreign body.




Management:

- Observation.

- Prophylactic topical antibiotics for small lacerations.

- Surgical repair may be required for large lacerations

Conjunctival Hemangioma


ophthalmology spot diagnosis - MIM  Nodhemangiomab

Clinical features:
Symptoms:

Small-sized tumor mostly asymptomatic or cause mild ocular irritation

Spontaneous bleeding or bloody tears.




Signs:

Benign, slowly progressive, bright red patch of vessels with sometimes ill-defined margins

Typically rounded, nodular, polypoid or lobulated, may grow and reach an enormous size of mass

May be found as an isolated lesion or associated with other ocular
capillary hemangiomas or systemic diseases such as Sturge-Weber syndrome

Multiple or multi focalized hemangiomas are usually independent and
separated from one another with little connection with the surrounding
vessels.

Management:
- Observation for increase in size, number of lesions, and morphological changes.
- Surgical excision, electrolysis and thermocoagulation have been used with success

Corneal Abrasion



Fluorescein is instilled in the
inferior fornix and the patient's eye is examined with blue light,
ideally with a slitlamp or magnifying loupe.

A corneal epithelial defect fluoresces under blue light.

Important: When using impregnated strips, wet the strip before instillation; otherwise the strip itself may cause corneal abrasion

vesicular rash in the distribution of the ophthalmic division (V1) of

The presence of the lesion on the tip of the nose (Hutchinson's sign)
increases the risk of ocular involvement
.

و بتحصل فى حالة blunt trauma

( a countercoup to post pole of the eye __> compression of retinal vessels __> retinal edema )

symptoms : rapid drop of vision

signs :
- pupil sluggish
- fundus > cherry red spots + retinal edema
> white color due to edema collected mainly in ganglion cell layer .
> the fovea still show the normal color of choroid

fate :
1 - resolution
2 - macular degeneration or macular hole

DD :
- from other causes of
1- cherry red spot
2 - other causes of rapid diminution of vision

TT :
rest ( if severe take systemic steroids )l



طيب نراجع مع بعض ايه اللى بيحصل فى حالت ال blunt trauma

حاجات كتير و بتتقسم على حسب المكان

نشوف ال retina كدة

_________

ممكن يعمل

1 - retinal tear تنتهى ب retinal detachment

2 - ممكن retinal hge و ساعتها تكون يا اما
- intra retinal

3 - ممكن تعمل retinal edema ديه شفناها فى المشاركة اللى فاتت
( commitoio retinae = berlin's edema )

اخيرا
4 - ممكن تعمل على طول retinal detachement
