Clinical data included history, ocular and<br>systemic examinations and neuro-imaging reports. Special attention was given<br>to the neurological data, which was the only source available to us for<br>diagnosing Meningiomas. Histological confirmation of Meningioma was available<br>in 9.6% cases (n = 9).<br>Results: Ninety – four patients, 51 females and 43 males (female: male ratio,<br>1.19:1) were included in the study. Mean age was 48.23 years. The commonest<br>type of Meningioma affecting visual pathway was Meningioma of inner table of<br>occipital bone causing mass effects on the occipital lobe (30.85%, n = 29). Other<br>Meningiomas were Parasellar (21.3%, n = 20) and supra sellar Meningiomas<br>(18.1%, n = 17) pressing upon optic chiasma. Tumor size ranged from 0.7 cm to<br>8.5 cm in smallest and largest dimensions respectively. Only one patient in our<br>series had neurofibromatosis type 1 and one patient had neurofibromatosis type<br>2.<br>Conclusion: Neuro-imaging including conventional radiology plays a pivotal role<br>in non-interventional diagnosis of intracranial Meningiomas. Owing to the benign<br>nature of Meningioma, it should be differentiated from other aggressive tumors<br>which need to be diagnosed and treated at the earliest.<br>Key words: Parasellar Meningiomas, Supra sellar Meningiomas, visual<br>pathway, Dural tail sign, Neuro-imaging</p>}, number={2}, journal={Pakistan Journal of Ophthalmology}, author={Khalid Farooq, Muhammad Khalil, Tayyaba Gul Malik,}, year={2015}, month={Jun.} }
