- Inflammation
In some cases, cataracts can lead to serious problems such as glaucoma and eye inflammation, which have been known to cause permanent loss of vision that cannot be corrected by cataract surgery. [goldbergeyemd.com]
Other symptoms that need quick attention are pain, double vision, fluid coming from the eye, and inflammation. [icdlist.com]
May progress rapidly to a mature cataract Pertinent clinical features Central opacity of the posterior cortical fibers Cortical cataract Posterior synechiae Papillary membrane Anterior chamber cell or flare Prior to phaco/ECCE Several months without inflammation [medrounds.org]
Congenital cataracts occur in newborns for many reasons: inherited tendencies, infection, metabolic problems, diabetes, trauma, inflammation, or drug reactions. [mcceyeinstitute.com]
Chronic inflammation (in addition to chronic steroid use) in the anterior chamber leads to breakdown of blood-aqueous and blood vitreous barrier which presents with a polychromatic lustre in the posterior poll of the lens. [quizlet.com]

Over one-third of the patients were found to have strabismus, refractive anisometropia, or some form of amblyopia. Seven other patients had additional ocular pathology which affected their visual prognosis. [ncbi.nlm.nih.gov]

Finally, our patients did not have corneal topography performed, so differentiation of lenticular from corneal astigmatism could not be made. [benthamopen.com]
After microkeratome-assisted removal of the anterior stromal layers, the presence of residual corneal opacities as well as their extent may be confirmed by the iOCT. [ijo.in]
- Esotropia
Two patients with bilateral cataracts had strabismus, one with intermittent esotropia and a second with intermittent exotropia. One patient with a unilateral ALO had an intermittent esotropia. [benthamopen.com]

- Nystagmus
Optic nerve hypoplasia, strabismus, and nystagmus: Macular hypoplasia is usually accompanied by noticeable optic nerve hypoplasia. [entokey.com]
Other coexisting eye problems, such as nystagmus, amblyopia, will persist even after removing the cataract and they need to be treated as well. [epainassist.com]
This condition then can lead to other eye problems such as nystagmus, strabismus and inability to fix a gaze upon objects. [allaboutvision.com]
Lamellar cataract did significantly better when compared with other morphologies in the non-traumatic group, similar to other studies. [10] Of the patients in the first category, 222 (17%) developed nystagmus at 2-4 months of age, which was accompanied [sjopthal.net]

Prognosis for Cataracts in Children The prognosis of children with congenital cataracts is good if treated early, i.e. within the first two months of the child's life. [epainassist.com]
The positive atoll sign will have more favorable prognosis since posterior capsule is intact, hence posterior chamber intraocular lens implantation will be more feasible with better visual prognosis. [jcor.in]
