[Isolated eyelid involvement as a rare presentation of orbital pseudotumor]

To report a case of isolated eyelid pseudotumor. A 40-year-old man presented with swelling and erythema of the right upper eyelid of 4 months duration. Multiple topical and systemic antibiotics had been administrated without any response. Incisional biopsy and evaluation of the lesion disclosed a diagnosis of eyelid pseudotumor. Oral prednisolone was initiated and then tapered slowly on the basis of clinical response. After six months, the eyelid lesion disappeared totally. Isolated eyelid involvement is a rare presentation of inflammatory pseudotumor of the orbit and should be considered in the differential diagnosis of eyelid lesions

[Comparison of mersilene mesh and autogenous fascia lata in ptosis correction]

To compare Mersilene mesh and autogenous fascia lata in the management of lowfunction ptosis. A randomized clinical trial was performed on 31 eyelids with poor levator function. Patients were randomly assigned to two groups: 16 eyelids in the Mersilene mesh group and 15 eyelids in the autogenous fascia lata group. Nine patients with congenital unilateral and 11 patients with bilateral ptosis underwent sling procedure. There was no difference between the two groups in terms of functional [lid fissure height stability] and cosmetic [lid margin contour] results. Dermatochalasis was seen more in the fascia lata group [10 cases] compared to the Mersilene mesh group [2 cases]. Extrusion of Mersilene mesh occurred in 2 eyelids. Mersilene mesh has favorable long-term functional results and a low rate of complication. This material may be an alternative to autogenous fascia lata as a suspensory material in ptosis surgery

Botulinum Toxin injection into inferior Oblique Muscle for treatment of acquired superior Oblique Palsy

To evaluate the effect of Botulinum toxin-A [BTA] injection into the inferior oblique [10] muscle in releaving the symptoms of superior oblique [SO] palsy.The study was conducted on patients who were referred for acquired SO palsy with less than 2 years of duration. About 10-20 unit of BTA was injected into the belly of the inferior oblique muscle through the inferotemporal quadrant of the involved eye without opening the conjunctiva. Results: Eighteen eyes from 16 patients were injected. Mean age was 33.7 years and mean duration of paresis was 6 months. Trauma was the cause of paresis in 81.2%. Six months after the injection, mean deviation decreased from 6.4 A to 1.9A; mean I0 over-activity decreased from +6.4 to +1.9; mean SO upper-activity decreased from -1.7 to -0.6; mean subjective torsion decreased from 9.3° to 0.4°; and mean head tilt decreased from 8.4° to 1.1°.Botulinum toxin-A injection into the 10 muscle can decrease the symptoms of patients with SO palsy and cause faster rehabilitation of these patients before stabilization of signs for final decision
