NO DRUG THERAPY IN PRIMARY CARE (RECOGNITION & REFERRAL)[1st line] Adult Malignant eye tumors comprise pediatric emergencies such as retinoblastoma and adult intraocular malignancies such as uveal melanoma. In infants and children, any presence of leukocoria (an abnormal white pupillary reflex on red reflex examination) or new- onset strabismus requires immediate emergency referral to a tertiary pediatric ophthalmology oncology service to prevent intracranial extension and metastatic death. In adults, suspicious features including enlarging pigmented choroidal lesions, unexplained visual field cuts, flashes, or persistent painful proptosis require fast- track ocular oncology evaluation. Do not prescribe eye drops or delay referral for outpatient observation. - Refer Peds Children follow the same pathway: recognise and refer. No primary-care medicine is implied. Source No dose - referral pathway, no medicine given in primary care Why Malignant eye tumors comprise pediatric emergencies such as retinoblastoma and adult intraocular malignancies such as uveal melanoma. In infants and children, any presence of leukocoria (an abnormal white pupillary reflex on red reflex examination) or new- onset strabismus requires immediate emergency referral to a tertiary pediatric ophthalmology oncology service to prevent intracranial extension and metastatic death.

Do not prescribe eye drops or delay referral for outpatient observation. Caution Rare in Egyptian primary care. No medicine is prescribed for this in primary care - this entry is for recognition and referral. Anything given is decided by the service it is referred to. Red flag signs including ophthalmoplegia, unilateral headaches, and unilateral nasal obstruction or recurrent epistaxis must not be ignored as they indicate extension/impending complications. RED FLAG - Rapid growth, vision loss, or bulging of the eye (proptosis) needs urgent referral to ophthalmic oncology.
