| A 21-year-old male presented with gradual decreased
vision in the right eye, and diagnosed with abnormal telangiectatic vessels
in the superotemporal periphery with submacular and extramacular lipid
exudation associated with tractional retinal detachment and foveal ectopia.

- Severe form of retinal telangiectasia
- Typically presents in the first decade; average age 5
- Clinical features:
- Signs:
- Telangiectatic vessels that appear as small, red "light
bulbs" in the retinal periphery
- Most often located in the inferior and temporal quadrants
between the equator and ora serrata
- Intraretinal and subretinal yellow exudation often affecting
areas distant from the vascular abnormalities
- Hard exudates commonly present in the posterior pole
- Leukocoria in patients who present with extensive subretinal
exudation
- Ultrasonography is useful to exclude retinoblastoma
- Differential diagnosis:
- Retinal capillary angiomatosis or hemangioma
- Late onset retinoblastoma
- Toxocara endophthalmitis
- Retinopathy of prematurity
- Familial Exudative Retinopathy
- Persistent primary hyperplastic vitreous
- Management:
- Cryotheraphy
- Laser photocoagulation to the telangiectatic vessels
- In advanced cases with total serous retinal detachment, external
drainage of subretinal fluid and scleral buckling may be an option
- Poor visual prognosis in cases of massive exudation
