Involvement of the eye and orbit in neurofibromatosis type 1
CH Gaonker, AK Mukherjee, Madhavi Pokle
January-March 1992, 40(1):2-4
11 individuals were diagnosed to have neurofibromatosis type 1 and were examined for evidence of any ophthalmic lesions. Lisch nodules were the commonest manifestation of the disease and were present in 73% of all the patients (88% of those aged 16 years or more). 55% of the cases showed presence of neurofibroma on the lids. Other findings were optic glioma, unilateral sphenoid dysplasia with enlarged orbit, medullated nerve fibers and prominent corneal nerves with an incidence of 9% each.

Unusual Marcus Gunn phenomenon in adults
SM Betharia, Kamal Kishore, Harsh Kumar
January-March 1992, 40(1):20-23
Two unusual cases of Marcus Gunn phenomenon in adults are presented. The first case was characterised by a bilateral jaw-winking phenomenon along with an asymmetric bilateral congenital ptosis, whereas the second case had bizarre spontaneous movements of the affected lid, deficient abduction and pseudoptosis in association with jaw-winking. The pathogenesis of Marcus Gunn phenomenon is discussed.

Immunotherapy in allergic conjunctivitis
OM Prakash, KR Murthy
January-March 1992, 40(1):9-10
Eighty patients with allergic conjunctivitis were treated with immunotherapy employing specific allergens. Sixty-two percent of these showed beneficial response. In cases of vernal conjunctivitis needing topical steroid preparations frequently for control of symptoms, immunotherapy is worth attempting to cause remission of symptoms.

Norries disease
JS Saini, Ashok Sharma, Premi Pillai, Kanwar Mohan
January-March 1992, 40(1):24-26
A 2-month-old male infant was found to have Norrie's disease. The clinical presentation and detailed histological features diagnostic of the disease are discussed. This is the first authentic, histologically proven case of Norrie's disease from India. The absence of hearing loss and mental retardation at the time of presentation at the early stage of infancy and the fact that the case was sporadic do not detract from the diagnosis. However the child at the age of one year developed hearing loss.

Mycotic keratitis : A study in coastal Karnataka
Subbannayya Kotigadde, Mamatha Ballal, Jyothirlatha , Anoopa Kumar, Srinivasa Rao P N, Shivananda P G
January-March 1992, 40(1):31-33
Fungi were isolated from 67 cases out of the 295 cases of corneal ulcers investigated. Aspergillus species and species of Candida were the major fungal members isolated. Allescheria boydii was isolated from 3 cases, having no previous history of injury to the eye or infection with bacterial or viral agents. A boydii corneal infection is a rare occurrence. Higher incidence of mystic keratitis was seen among females than males. No relationship to seasonal changes could be established. Bacterial infection was associated in 46. 27% of the cases of mycotic keratitis and Staphylococcus was the predominant bacterial pathogen observed.

Bilateral proptosis due to metastatic Ewing's sarcoma of the orbit : fine needle aspiration cytology (FNAC) and histopathology of a case
AK Khurana, BK Ahluwalia, S Gupta, Choudhry Rajan, BB Arora
January-March 1992, 40(1):15-17
Bilateral proptosis due to metastatic Ewing's sarcoma is an extremely rare presentation and thus merits reporting. The role of fine needle aspiration cytology in the diagnosis is highlighted.

Ultrasonic study to see the effect of topical pilocarpine and homatropine on anterior chamber depth in phakic cases
AS Mehrotra, ILA Gupta, BS Chouhan
January-March 1992, 40(1):5-8
Pilocarpine and Homatropine are the drugs having known effect on the depth of anterior chamber. The purpose of this study was to demonstrate the time of onset, peak effect and its duration of action as well as shallowing/deepening of the anterior chamber, after single instillation of pilocarpine 2% or homatropine bromide 2%, topically in one eye. Also we tried to see if there is any effect on the contralateral eye, due to systemic absorption of pilocarpine, homatropine after topical instillation of the drug in one eye. Pilocarpine causes a measurable shallowing of the anterior chamber with onset of effect with in 20 minutes and a peak in 60 minutes, the average narrowing being 0.26 mm. (range 0.20-0.29 mm.). Homatropine has a measurable deepening effect on the anterior chamber, due to axial flattening of the lens because of cycloplegia, with a range of 0.33 to 0.36 mm. In 70% of the cases the effect passes away with in 24 hours., but in 30% it comes to normal in 48 hours.

Effect of SH reagents on rod photoresponse of isolated frog retina
SA Salehi, M Takagi, T Shinozawa, T Matsuura
January-March 1992, 40(1):11-14
Several SH reagents, N-ethylmaleimide (NEM), p-chloromercuribenzoic acid (PCMB), p-chloromercuribenzene sulphonate (PCMBS) and monoiodoacetic acid (MIAA) changed the wave form and the peak of the amplitude of the photoresponse remarkably. The effects of amino group modifying reagents, ethyl acetimidate (EA) and isethinyl acetimidate (ITA) on photoresponse were very slight. The possibility of a SH protein as cGMP-sensitive cation channel protein is discussed.

Use of beta radiation to control I.O.P.
Shabbir Saifuddin Adenwala, L Otto Erich
January-March 1992, 40(1):27-28
The use of ophthalmic applicator containing Strontium-90 beta ray was used to bring about a change in I.O.P by its effect on the ciliary body. The change in 1.0.11 depends on the degree of damage done to the ciliary body. The study showed that the change in 1.0.11 was directly proportional to the intensity of beta rays application - higher the dose of beta radiation more was the damage and more the reduction in 1.0.P.
