| Introduction|| |
Myasthenia gravis is a disease characterised by fatigue and weakness of the striated muscle within the body. Although the exact cause is unknown it is thought to be an acquired autoimmune disorder; the defect lies at the post synaptic membrane
In myasthenia gravis asymmetrical involvement is common, although it is rare to find significant involvement of one eye with no involvement of the other eye. Here we are presenting a, unilateral case who has significant involvement of one eye with no involvement of the fellow eye.
| Case report|| |
Patient Natrpal, 18 years, male, admitted in our hospital for drooping of the right eye since 6 months, on examination anterior and posterior segments were normal, visual acuity was 6/6 in both eyes, no phoria for distance and near, movements of the eye ball were full in all directions of gaze, amount of ptosis in the right eye by difference in palpebral fissure width was 5mm, by marginal reflex distance (MRD) was also 5 mm, levator palpebre superioris (LPS) action by Berke'sz method was 7 mm in the right eye.
Bells phenomenon was absent.
Cogner lid twitch sign was positive ,.
Neostigmine test was positive.
The patient was given tablet Neostigmine 15 mg three hourly and tablet Prednesolone 5 mg bd. The response to the drug was dramatic and the patient felt better.
| Discussion|| |
Ophthalmic involvement in myasthenia gravis is not an uncommon feature, but it is very rare to find a case of unilateral ophthalmic myasthenia gravis without the slightess involvement of the other eye. This patient was kept under watch and the diagnosis was confirmed clinically and by the neostigmine test. Literature is scanty on this unilateral involvement.
