Methanol-induced optic neuropathy: treatment with intravenous high dose steroids.

The aim of this study was to find the potential benefit of intravenous high dose steroids in the treatment of patients with methanol optic neuropathy. Four patients complaining of diminution of vision after taking methylated spirit presented to us within a variable period of its consumption. The systemic features of methanol poisoning were absent in these patients. Raised blood levels of methanol confirmed the diagnosis of methanol optic neuropathy. All these patients received high doses of intravenous steroids for three days, followed by oral steroids, 1 mg/kg body weight, for 11 days. The administration of high doses of intravenous steroids led to an improvement of visual status in all four patients. Intravenous high dose steroids benefit the visual status of patients with methanol-induced optic neuropathy, provided the interval between the consumption of methanol and starting treatment is short. Further studies should be undertaken to document the role of intravenous steroids in this context.

Oculocutaneous manifestations in xeroderma pigmentosa.

Xeroderma pigmentosum (XP) is a rare genetic disease characterised by defective DNA repair leading to clinical and cellular hypersensitivity to ultraviolet radiation. The oculocutaneous features of 10 patients with XP were studied retrospectively. General features included parental consanguinity (40%), familiarity (60%), onset of symptoms in first 2 years (50%), malignant skin neoplasms (60%), and carcinoma of the tongue (20%). Among the ocular features, 50% of patients presented with photophobia. Lid freckles or atrophic skin lesions were seen in all patients. Lower lid tumours were seen in 30%, chronic conjunctival congestion in 40%, corneal opacification in 40%, squamous cell carcinoma of limbus in 20%, bilateral pterygium in 40%, and visual impairment in 50%. The clinical features (ocular and cutaneous) of the cases are discussed.

Spectrum of oculomycosis in South India.

Ninety-one consecutive cases of proven oculomycosis were studied in relation to clinical features and epidemiological parameters. Mycotic corneal ulcers formed the major group (76%), followed by endophthalmitis (20%). Aspergillus was the common causative fungus (36%) in keratomycosis followed by Penicillium species (29%). Fusarium keratomycosis was not as common as reported in the literature. In endophthalmitis there was preponderance of Penicillium as the causative fungus. These etiological agents are studied in comparison with studies of conjunctival flora of healthy controls and culture studies of common objects of trauma. Mycotic endophthalmitis was seen following cataract surgery in 64% of cases. Contrary to expectations the onset of endophthalmitis was within 2 weeks of surgery in most cases. Trauma with organic matter was an important predisposing factor in keratomycosis. These observations are discussed in relation to the clinical features. Other unusual forms of oculomycosis are also discussed.

Corneoscleral ulceration in congenital erythropoietic porphyria (a case report).

A case of congenital erythropoietic porphyria, with corneoscleral ulceration, a rare association in this disorder, was reported. Anterior segment ischemia is believed to play an important role in the etiopathogenesis of corneoscleral ulceration. Remarkable improvement occurred with use of topical heparin drops (500 units/ml).

Lactate dehydrogenase levels in aqueous humor and serum in retinoblastoma.

The lactate dehydrogenase (LDH) levels were measured in the aqueous humor and serum of 16 patients (20 eyes) with retinoblastoma. The enzyme activity in the aqueous humor and serum did not show any correlation with each other. Age of presentation, age of enucleation, sex and disease duration had no correlation with the enzyme level either in the serum or aqueous humor. The stages of retinoblastoma were classified in Stages I to V: eyes with Stages I to III were included in Group 1, and those with Stages IV and V were in Group 2. The differences in LDH levels in the aqueous humor and in the aqueous to serum LDH ratio were highly significant (P less than 0.001) by Wilcoxon's nonparametric test between Groups 1 and 2. A considerable rise in the aqueous humor LDH level was observed without any alterations in the serum levels in Group 2 as compared to Group 1; hence the aqueous/serum ratio was increased in the former group. The LDH level in the aqueous humor and the aqueous/serum ratio can be a diagnostic tool in retinoblastoma of Stages IV and V. Though the lower aqueous levels of LDH do not rule out the presence of the disease, the higher levels are definitely helpful for diagnosis of retinoblastoma.
