In the fields of optometry and ophthalmology, the Hirschberg test, also Hirschberg corneal reflex test, is a screening test that can be used to assess whether a person has strabismus (ocular misalignment).
Maloney's research is focused on developing new technologies for vision correction surgery, including the implantable contact lens and the light-adjustable lens implant, and on complications of vision-correction surgery.

The surgery is often performed under local anaesthesia. Through a small incision made on the medial side of the big toe, a wedge-shaped piece of the bone is removed from the proximal phalynx. The toe is then realigned to its correct position and secured using pins, screws or a plate.
Refractive surgery causes only minimal size differences, similar to contact lenses. In a study performed on 53 children who had amblyopia due to anisometropia, surgical correction of the anisometropia followed by strabismus surgery if required led to improved visual acuity and even to stereopsis in many of the children [9] ( see: Refractive ...
The signs and symptoms of far-sightedness include blurry vision, frontal or fronto temporal headaches, eye strain, tiredness of eyes etc. [2] The common symptom is eye strain. Difficulty seeing with both eyes ( binocular vision) may occur, as well as difficulty with depth perception. [1] The asthenopic symptoms and near blur are usually seen ...
A vomer flap is a type of palatoplasty surgery that uses the mucoperiosteal tissue of the vomer to cover a unilateral or bilateral cleft palate. This procedure can be used to reconstruct the nasal or oral surfaces by either raising the vomer or creating a flap. Surgical procedures can be combined according to type of clefting in order to ensure ...
Convergence insufficiency may be treated with convergence exercises prescribed by an eyecare specialist trained in orthoptics or binocular vision anomalies (see: vision therapy ). Some cases of convergence insufficiency are successfully managed by prescription of eyeglasses, sometimes with therapeutic prisms .
