HYPERTENSIVE RETINOPATHYHYPERTENSIVE RETINOPATHY
• WHO definition:WHO definition:• Systolic blood pressure >140 mm Hg • Diastolic blood pressure > 90 mm Hg
• HTN can affect the choroid, retina, and optic nerve
• HTN may cause cranial nerve palsies that affect extraocular motility, and strokes that result in visual field defects

Grade Description
1Mild retinal vascular changes (generalized arteriolar narrowing).
2Moderate to severe retinal vascular changes Moderate to severe retinal vascular changes (arteriovenous crossing and nicking changes).(arteriovenous crossing and nicking changes).
3Stage 1 and 2 findings, plus cotton-wool spots, retinal hemorrhages and exudates.
4Stage 3 findings, plus associated optic nerve head swelling and macular star formation.
DYSTHYROID EYE DISEASEDYSTHYROID EYE DISEASE(TED)(TED)
associated with disease of the thyroid gland
Commonly occurs with an overactive thyroid (Thyrotoxicosis):
Grave’s disease
Toxic Nodular Goitre
It also occurs in hypothyroidism: eg: Hashimoto’s disease

ProptosisProptosis• Occurs in about 50%
• Axial and permanent in about 70%
• Unilateral or bilateral
• due to inflammation of the extraocular muscles
and orbital fat
• May be associated with choroidal folds.
• Average readings are 15 to 17 mm for adults with range of 12 to 22 mm Difference between the two eyes of greater than 2 mm is significant for this test

ANTERIOR SEGMENT
• Conjunctival injection and chemosis
• Superior limbic keratitis
• Dry eyes
• Exposure keratopathy
• Episcleritis/Scleritis
• Glaucoma
INTRAOCULARINTRAOCULAR
POSTERIOR SEGMENT
• Choroidal folds
• Macula oedema
• Optic disc swelling
Axial CT scan markedly enlarged recti muscles compressing the optic nerve
Management• Monitor all patients closely during their inflammatory
phase to ensure they do not develop optic nerve compression or corneal exposure
• Patients with severe orbitopathy may require orbital bony decompression, external beam radiation of the orbit, steroids, or a combination of all three modalities
• In general strabismus and eyelid procedures are not performed until the phase of active inflammation has subsided, (and following orbital decompression if decompression is required)

Clinical manifestationsClinical manifestations
• mild flu-like symptoms, prolonged glandular – fever type illness
• If the infection occurs early in the pregnancy, the baby may be miscarried or stillborn.
• If infected between the third and sixth month of pregnancy, the baby may develop some or all of the following severe symptoms: - – Hydrocephalus
(An excess of fluid on the brain) – Brain Lesions
(Scarring of the brain tissue) – Eye damage
(Retinochoroditis)
Fundus findings
• Solitary
• Round
• Pigmented punched out retinal scar

Molluscum contagiosumMolluscum contagiosum• viral infection of the
skin.• painless, small,
umbilicated nodules, which produce a waxy discharge
• Treatment – excision – curettage – cryotherapy
Kaposi’s sarcomaKaposi’s sarcoma• vascular neoplasm which
is almost exclusively seen in patients with HIV.
• The mainstay of treatment is radiotherapy.
• Other options include cryotherapy or chemotherapy.
HIV retinopathy HIV retinopathy
CMV retinitisCMV retinitis
• most common opportunistic infection in HIV, usually seen when CD4 <50
• CMV retinitis was easily recognized as a “tomato ketchup in mozzarella cheese appearance” . ie Retinal haemorrhages along edge or within the areas of necrosis.
TREATMENTTREATMENT• GANCICLOVIRGANCICLOVIR
– reverse transcriptase inhibitors– Analog of guanosine – Virostatic
– Mode:• Intravenous• Oral• Intravitreal• Implant
TREATMENTTREATMENT• HAART (Highly active antiretroviral HAART (Highly active antiretroviral
therapy)therapy)– a combination of protease inhibitors taken with
reverse transcriptase inhibitors
Protease inhibitor :– indinavir
• Nucleotides reverse transcriptase inhibitors:– Combivir (zidovudine / lamivudine) – Retrovir (Zidovudine, AZT)
PrognosisPrognosis• 80-95% will respond, with resolution of
intraretinal hemorrhages and white infiltrates.
• If treatment is discontinued and the individual is still immunocompromised (ie, CD4 <50) – retinitis will recur in 100%.
• Prior to the advent of HAART,– 50% of patients would experience recurrence within 6
months despite maintenance therapy. – This rate is reduced if the CD4 count is elevated.
PrognosisPrognosis
• Untreated retinitis will progress to blindness from
– retinal necrosis,– optic nerve involvement, or– retinal detachment.
