Multivariated analysis of corrected visual acuities after extraction of congenital cataract with IOL implantation in 24 patients (41 eyes), including 14 children (22 eyes) under 12 years of age, revealed that 6 factors significantly affected the postoperative results, namely, the pattern of lenticular opacity, monocularity, strabismus, nystagmus, after-cataract formation and its time of onset. Therefore, operation as early as possible is recommended for cases with these factors and IOL implantation considered, with discretion, in children for whom other forms of visual aids are not available.

Intraocular tumours may be benign or malignant. The latter are more numerous, and endanger not only vision but life as well. Two of them deserve special attention: melanoma malignum oculi in adults and retinoblastoma in children. Melanoma malignum may arise from all three areas of the uvea: the iris, the ciliary body and the choroid. The more malignant growths are those which are situated closer to the posterior pole. Histologically the epitheloid cell-type of melanoma is more malignant than those containing only spindle cells. Their treatment depends on the size: in the case of large tumours enucleation is required, while for the smaller ones, radiation therapy can be applied. Retinoblastoma is most common in children of 1-2 years of age. It has familial and sporadic forms. Sixty-seven percent of the inherited-type cases are bilateral. An early symptom in small children is strabismus. A white tissue mass growing into the vitreous is seen on the fundus. A diagnostic feature that can be detected by ultrasound examination is calcification. The tumour may also present intracranially, therefore CT of the skull should be performed in each case. Histologically the tumour contains malignant neuroepithelial cells, which may form a rosette. In the case of large tumours the treatment is enucleation; in bilateral processes the bulbus with the larger mass is removed and the other eye is treated with radiation therapy. In both cases chemotherapy is used according to a prescribed schedule. Metastases to the eye occur most frequently from carcinomas of the breast, lungs or gastrointestinal tract. These are treated with radiotherapy, chemotherapy and hormone therapy. Primary intraocular lymphoma often occurs bilaterally, and may be accompanied by primary lymphoma of the central nervous system (CNS). Some benign tumours are found by chance on routine eye examinations, others due to subjective and objective symptoms.
