Infants And Young Children

Many abnormalities of the visual system in infants and young children respond to treatment when instituted at an early age. Ocular abnormalities that require early recognition and therapy include congenital cataracts, congenital glaucoma, intraocular tumors, intraocular inflammation, large errors of refraction, strabismus, and corneal opacities (Figs 1 to 6). The visual prognosis for children with these problems is often directly related to early detection and treatment of the visual disorder. Visual deprivation of young laboratory animals can permanently damage their developing central nervous system. Diseases once believed hopeless, such as monocular congenital cataracts, can now be treated.1 Technologic advances, such as extended-wear contact lenses which are useful for infants who have had cataract surgery during the first few weeks of life, have facilitated visual rehabilitation of young eyes. Corneal opacities, complete ptosis, prolonged patching, and eyelid or orbit abnormalities such as large hemangiomas can cause amblyopia if the vision is obstructed. Even brief occlusion can result in irreversible amblyopia during the early months of life.2 Unilateral disruptions of vision are generally more damaging to the eye than are bilateral ocular abnormalities. Each of the young child's eyes must enjoy a clear, focused retinal image for visual development to progress normally. Early diagnosis and treatment of congenital glaucoma is important so that intraocular pressure can be lowered, thereby, avoiding irreversible anatomic damage to the eye.

Purpose: To compare the stereoacuity between patients with anisometropic amblyopia who were treated and achieved normal visual acuity (VA) and normal children and evaluate the factors associated with stereoacuity.Methods: We retrospectively reviewed the records of 37 pediatric patients with anisometropic amblyopia who recovered to normal VA with glasses and occlusion treatment (amblyopia group) and 34 normal children (control group). The Worth 4-dot test, Lang II test, Titmus test, and TNO test were performed to measure stereoacuity. Clinical characteristics were compared between the two groups, and factors affecting stereoacuity outcomes were also analyzed in the amblyopic group.Results: The mean age at diagnosis of amblyopia was 5.3 ± 1.4 years, and the mean VAs at diagnosis were 0.41 ± 0.24 and 0.06 ± 0.07 in amblyopic and fellow eyes, respectively. The mean duration of occlusion was 19.00 ± 9.44 months, and VA of amblyopic eyes improved to 0.04 ± 0.04 after occlusion treatment. The patient characteristics did not differ significantly between the two groups, except for the final VA of the amblyopic eye. The final mean logarithm of minimal angle of resolution VA of the amblyopic eye in the amblyopia group was significantly worse than that in the control group. The number of patients with normal stereoacuity was significantly lower in the amblyopia group than in the control group on Lang II, Titmus, and TNO tests. Factors associated with poor stereoacuity were severe amblyopia in the Lang II test and poor post-treatment VA of the amblyopic eye in the Titmus test.Conclusions: Stereoacuity was worse in the amblyopia group than in the control group, despite normal visual development. The depth of amblyopia and post-treatment VA were associated with stereoacuity outcomes. Thus, VA improvement should be closely monitored in the amblyopic eye to obtain good stereoacuity.
