In hyperparathurodism
Calcium may precipitate in cornea
called = Band keratopathy
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
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
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
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

Inferior Rectus Entrapment
The inferior rectus muscle is
entrapped within the blowout fracture. When the patient tries to look
upward, the affected eye has limited upward gaze. The patient
experiences diplopia with this maneuver

Dacryocystitis
Dacryocystitis is infection of the lacrimal sac, usually
secondary to nasolacrimal duct obstruction. This image shows acute
dacryocystitis; chronic dacryocystitis manifests as a mass with signs of
chronic conjunctivitis
Open Globe
[size=12]This injury is not subtle; extruded ocular contents (vitreous) can be seen; a teardrop pupil is also present
Nits
Nits (the larval form of the louse) from Phthirus pubis
are seen firmly adherent to the eyelashes in this child. ***ual abuse
should be considered
Herpes Zoster Ophthalmicus
A healing
vesicular rash in the distribution of the ophthalmic division (V1) of
the trigeminal nerve is present in this 72-year-old diabetic patient.
The presence of the lesion on the tip of the nose (Hutchinson's sign)
increases the risk of ocular involvement.
Glaucomatous Cupping
The cup is not central; it is elongated toward the rim superotemporally.

Cytomegalovirus (CMV) Retinitis
CMV
Retinitis "Pizza pie" or "cheese and ketchup" appearance is demonstrated
by hemorrhages and the dirty, white, granular-appearing retinal
necrosis adjacent to major vessels.

berlin's edema
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
- sub hyaloid
3 - ممكن تعمل retinal edema ديه شفناها فى المشاركة اللى فاتت
( commitoio retinae = berlin's edema )
اخيرا
4 - ممكن تعمل على طول retinal detachement
