A total of 261 adverse ocular reactions occurred in 237 patients who received isotretinoin, a commonly used drug in the treatment of severe cystic acne. Blepharoconjunctivitis, subjective complaints of dry eyes, blurred vision, contact lens intolerance, and photodermatitis are reversible side effects. More serious ocular adverse reactions include papilledema, pseudotumor cerebri, and white or gray subepithelial corneal opacities; all of these are reversible if the drug is discontinued. Reported cases of decreased dark adaptation are under investigation. Isotretinoin is contraindicated in pregnancy because of the many reported congenital abnormalities after maternal use (including microphthalmos, orbital hypertelorism, and optic nerve hypoplasia).

The epidemiological and clinical features of primary herpes simplex virus ocular infection in 108 patients were studied. Of these, 69 (64%) were aged 15 or over and only eight (7%) were under the age of 5. Associated upper respiratory tract infection was found in 38 (35%) patients and systemic disorders such as mild malaise, fever, and aching in 34 (31%) patients. Common symptoms were redness, watering, discharge, itching, irritation, and lid swelling, whereas pain, photophobia, lid vesicles and ulcers, and blurred vision were less frequent. The major signs consisted of vesicles and ulcers on the lids, papillary responses which were more severe in the upper lid conjunctiva, follicles which were more common in the lower lid conjunctiva, fine and coarse epithelial punctate keratitis, and subepithelial punctate keratitis. Dendritic ulcers and disciform keratitis were found in 16 (15%) and two (2%) patients respectively. The clinical forms of primary herpes simplex virus ocular infection varied. Moderate or severe disease was observed in 41 (38%) and 16 (15%) patients respectively. In eight (7%) patients the disease presented as an acute follicular conjunctivitis without characteristic lid or corneal lesions. A chronic blepharoconjunctivitis which lasted for months developed in 16 (15%) patients. The epidemiological and clinical features in our patients were compared with features of the disease reported previously.

Sinonasal lymphoma, a rare nonepithelial malignant tumor often originates from the nose and paranasal sinuses. Typically, these lymphomas present with symptoms of nasal obstruction, discharge, epistaxis and facial swelling. Orbital extension results in ocular symptoms like proptosis, blurred vision and diplopia. In this case report, we describe persistent blepharoconjunctivitis, an unusual ocular presentation of sinonasal lymphoma. The tumor was positively identified with immunoreactivity of biopsy specimen; Appropriate chemotherapy lead to successful remission of the disease.
