Department of Opthamology, Sultan Qaboos University Hospital, Muscat, Sultanate of Oman.

Background: Pregnancy is a well-known risk factor for central serous chorioretinopathy (CSCR). Methods: Patients were examined using slit-lamp biomicroscopy, fundus examination, fundus photography, and optical coherence tomography, making note of best-corrected visual acuity. Results: All patients had resolution of CSCR. Interpretation: We present CSCR in 3 consecutive pregnant women without subretinal exudates.

Cortical visual loss consequent to brain metastases from an endometrial carcinoma

Brain metastases secondary to endometrial carcinoma are very rare and are indicative of widespread dissemination in the body. A literature review showed few reports of cortical visual impairment (CVI) secondary to brain metastases. We present a rare case of CVI secondary to central nervous system (CNS) metastasis from an endometrial carcinoma.

Tolosa-Hunt syndrome: MRI appearances

A review of MRI findings in seven patients with Tolosa-Hunt syndrome was carried out. Seven patients presented with unilateral painful ophthalmoplegia. Magnetic resonance imaging studies were carried out to evaluate the cavernous sinuses and orbits. Coronal fast spin-echo T2-weighted images and fat-saturated T1-weighted coronal and transverse images with and without contrast enhancement were obtained for the cavernous sinuses and orbits. All patients showed focal-enhancing masses expanding the ipsilateral cavernous sinus. In one patient the mass was extending to the orbital apex and intraorbitally. All patients recovered on corticosteroid therapy and resolution of the masses was documented on follow-up MRI studies in five patients. One patient had a relapse of symptoms after discontinuing therapy. Magnetic resonance imaging studies of the cavernous sinus and orbital apex show high sensitivity for the detection and follow up of inflammatory mass lesions in Tolosa-Hunt syndrome. Magnetic resonance imaging should be the initial screening study in these patients.

Objectives: The corneal disease is a priority problem in Oman. We present patients with contact lens (CL) induced severe keratitis, admitted in the corneal unit of Al Nahdha Hospital in Oman. Methods: The study was conducted in 2005-2006. Ophthalmologists examined the eyes using slit lamp bio-microscope. Visual acuity was noted using Snellen's distance vision chart. Specimens of corneal scraping and CLs were sent for culture and sensitivity tests. Patients with severe keratitis were admitted and treated with medicines. Corneal and visual statuses were noted at the time of discharge from hospital and after six weeks. Numbers, percentages and their 95% confidence intervals were calculated. Pre- and post-treatment vision were compared using a scattergram. Results: The 52 eyes of 15 males and 37 female patients with corneal ulcers were examined. Thirty-two patients were between 20 to 30 years of age. Only 13 (25%) patients had visited an ophthalmologist within 24 hours of developing severe keratitis. Seventeen (33%) had central ulcers and six (11.5%) had ulcer ≥5 mm in size. Pseudomonas was found in 29 (55.8%) of CL and corneal material scraped from the eyes of 5 (28.8%) patients. Vision was <6/60 (legally blind) in 12 (23.1%) eyes before and in five (9.6%) eyes after treatment. Twenty-six (50%) patients were lost to follow up. Conclusion: CL related severe keratitis causes visual disabilities. Prevention and proper records are essential. Treatment improves vision and hence facilities for management should be strengthened.

Objective: Pseudoexfoliation (PEX) syndrome is one of the leading causes of secondary open angle glaucoma and blindness. This study explored whether in PEX eyes, preoperative changes in corneal endothelial cell morphology might be a risk factor for postoperative corneal decompensation. Methods: One hundred twenty six eyes of 69 preoperative cataract patients (43 males, 26 females) were enrolled in this cross-sectional study from the Ophthalmology Department at Sultan Qaboos University Hospital between 2003-2005. All patients were subjected to confocal biomicroscopy. Results: The mean age of patients with PEX eyes was 63.2 years. One hundred and eight (85.7%) eyes with PEX had endothelial cell counts within the normal range (1650-3500/mm˛). The qualitative morphology of the endothelium of PEX corneas was highly abnormal in term of polymegathism and pleomorphism. Twelve eyes had endothelial cell counts higher than normal for that age group. Only 6 eyes had endothelial cell counts lower than normal. The mean value for the pleomorphism was found to be significantly lower than normal and for polymegathism significantly more than normal. The relationship between pleomorphism and polymegathism was stronger for males than for females and stronger for patients under 60 years than patients over 60 years. The same relationship between pleomorphism and polymegathism showed a stronger relationship for the glaucoma group as compared to the non-glaucoma group. Conclusion: This study revealed that corneal decompensation in PEX eyes can occur in presence of abnormalities in polymegathism and pleomorphism, even when the endothelial cell counts may be normal.
