SIBELLO DEUSTUA, Sirley et al. Monocular elevation deficiency with esotropia. Rev Cubana Oftalmol [online]. 2019, vol.32, n.3, e648.  Epub 01-Set-2019. ISSN 0864-2176.

Monocular elevation deficiency is defined as a limitation in the elevation of the affected eye from any position of gaze with normal ductions in all other positions. Pseudoptosis may occur in the primary position of gaze, but 25% of the cases are true ptosis. A case is presented of a male 11-year-old patient with a history of inward strabismus since birth, treated with occlusions and lenses as of his first year of life. At ophthalmological examination, best corrected visual acuity was 1.0/0.4; at 6 meters in the right eye 30 ∆ b outer ~18 ∆ b upper, and in the left eye 30 ∆ b outer ~18 ∆ b lower; at 33 centimeters in the right eye 30 ∆ b outer ~25 ∆ b upper, and in the left eye 30 ∆ b outer ~25 ∆ b lower, and elevation limitation in all horizontal gaze positions of the right eye. The forced duction test revealed a restriction in the lower right rectus muscle. It was thus decided to insert back the right rectus muscle and both medial rectus muscles. Optical correction and rehabilitation with occlusions improved the patient's vision to 1.0/0.7. Corrective surgery achieved orthotropy and improved visual acuity.
