“…In comparison to blurred images, if there is no stimulation of light, studies show that it slows down the progress of blurred induced myopia and AL elongation. In theory, clearing up the image blur would abolish the stimulus of image blur on AL elongation, thereby retarding AL growth and the process of emmetropization, thereby causing hypermetropia [45]. In addition to the influence of AL elongation by blurred image stimulation of the retina, it seems that intrinsic growth of the eye is disengaged from visual input.…”

Congenital nasolacrimal duct obstruction (CNLDO), previously considered a benign disease, affects 20% of the children globally. It is described by a collection of symptoms in which continuous epiphora and intermittent discharge are present in either one or both the eyes. CNLDO usually resolves in most healthy infants in the first few couple of months; however, it may persist for a number of years in some children. There has been a lot of recent deliberation on how a constant watery eye affects the visual development during the phase of emmetropization in children. A connection between CNLDO and anisometropia has been hypothesized. Multiple factors which include developmental and environmental aspects are thought to play a contributory role in the development of anisometropia by and large; particularly hypermetropic anisometropia, raising the chances of developing amblyopia in children with CNLDO. Published literature on CNLDO had shown inconclusive evidence on this anecdotal propinquity. This chapter discusses CNLDO; etiology, pathogenesis, treatment modalities, surgical intervention, and its role in inducing refractive errors; and its propensity to cause amblyopia.

“…These sequelae of ptosis provide a compelling reason to pursue early surgical correction 1112. This is particularly true in cases of congenital ptosis since clearance of visual axis is essential for prevention of visual loss related to amblyopia.…”

Ptosis refers to vertical narrowing of the palpebral fissure secondary to drooping of the upper eyelid to a lower than normal position. Ptosis is considered congenital if present at birth or if it is diagnosed within the first year of life. Correction of congenital ptosis is one of the most difficult challenges ophthalmologists face. Multiple surgical procedures are available including, frontalis sling, levator advancement, Whitnall sling, frontalis muscle flap, and Mullerectomy. Selection of one technique over another depends on the consideration of several factors including the surgeon experience, the degree of ptosis in the patient, as well as the degree of levator muscle function. Current recommendations for the correction of congential ptosis vary based on clinical presentation. Advantages and disadvantages of each of these procedures are presented with recommendations to avoid complications.

“…CBP is often associated with numerous visual system disorders, mainly amblyopia, strabismus, anisometropia or astigmatism, which should be well known both to ophthalmologists and plastic surgeons who eventually decide on surgical intervention (8,9). The treatment requires clinical analysis to select the appropriate operative method.…”
