7. ISIRIT can cause constriction of the pupil, blurred vision, tearing, and pain because the iris becomes inflamed. 8. EARBOPYIPS occurs when the lens hardens with age and loses its ability to accommodate near visual tasks, which results in people holding reading materials at arms length. 9. ACOALGUM involves damage to the optic nerve when the intraocular pressure increases because of the inability of the eye(s) to drain off excess aqueous humor. 10. TACARCAST, cloudiness or opacity of the lens, occurs primarily in the elderly (although it can occur in children) and is treated by surgical removal of the lens. 11. AIDAIRIN is the total or partial absence of the iris and often occurs with Wilm's Tumor. Effects include reduced acuity, restricted fields, and photophobia. Glaucoma and cataracts may also occur. 12. LABTHUMPSOH is a form of glaucoma that appears within the first three years of life. 13. VIESUIT involves inflammation of the choroid, iris, and/or ciliary body, which can cause pain, blurry vision, and photophobia. This condition tends to occur in conjunction with histoplasmosis, tuberculosis, and toxoplasmosis. = 79 CONTENTS
