Repeated vitreous haemorrhage is a common occurrence in Eales disease. 25 eyes of unresolving vitreous haemorrhage were subjected to pars plana vitrectomy. 18 eyes improved to 1/60 or better. Vitreous rebleed was the commonest problem encountered. We discuss our experience, complications and limitations.

Ten consecutive cases of perforating ocular injuries with retained intraocular foreign bodies over a period of 2 years were reviewed retrospectively in this study. All cases were operated upon by a 3 port pars plana vitrectomy and if necessary endolaser done. All ten cases (100%) were successful in terms of intraocular foreign body removal through the pars plana sclerotomy but ultimately we lost three [3] [30%] cases of which two had retinal detachments with P.V.R. D-3 preoperatively and the other had endophthalmitis. Of the seven (70%) successful cases four eyes (40%) had a post-operative vision of 6/12 or better while 2 [20%] had 6/24 and the last had 6/60 [10%]. Nine cases [90%] had a magnetic Intraocular foreign body. Various complications of Intraocular foreign bodies like vitreous haemorrhage, retinal incarceration, cataract and retinal detachment were noted preoperatively. Silicone oil was used in three (30%) cases. Sulfur Hexafluoride was used in 5 cases (50%). Endolaser photocoagulation was done in 7 cases (70%).

Among 100 cases of primary glaucomas, 50 cases were operated for trabeculectomy by making fornix based flap and 50 cases were operated by fashioning limbal based conjunctival flap. Operative and post operative complications were studied thoroughly in the two groups. All the cases were followed up for six months to one year to assess control of intra ocular pressure, nature and functioning of filtering bleb, field changes and visual status in the two groups. It was found that the fornix based flap is much superior and carries various advantages over the limbal based flap. The operative and post operative complications are minimum in the fornix based flap as compared to the limbal based flap.

A cohort of 50 anisometropic amblyopes, between the ages of 2.5 to 10 years, was studied retrospectively to assess the prognostic significance of visual acuity for near over that for distance. There is ample evidence in the literature for a significantly lower accommodative response in the anisometropic amblyopic eye. It has been proposed that the efferent accommodative dysfunction may be a fundamental and causative factor in anisometropic amblyopia. A reduced visual acuity for near over that for distance was found in 17 [34%] patients and in 11 out of these the near vision improved after an addition of +3.0D sph. When a reduced visual acuity for near, was obtained it was difficult to determine whether the visual afferent system (due to insufficient visual input), or the accommodation efferent mechanism was responsible. However an improvement in corrected near vision by addition of +3.0D sph. suggested an accommodative dysfunction. In patients with reduced visual acuity for near over that for distance, not only was the final visual outcome poor but also the onset of visual improvement in response to amblyopia therapy was delayed.

This study is an analysis of five cases of orbital trauma causing proptosis, paralysis of extraocular muscles with or without associated visual failure. All the cases were treated by a Neurosurgical team. Either a frontal craniotomy or a lateral orbitotomy was performed. Plain X-rays of the skull and Computerised Tomography (C.T. Scanning) were the main investigations. Results were encouraging both functionally and cosmetically. Early diagnosis and an aggressive approach to orbital decompression can achieve good results.

Xerophthalmia is a commonly encountered nutritional disorder that affects the growing population of the world. Conjunctival and corneal epithelial cells contain peroxidase enzyme. In experimentally induced Vitamin A deficiency conjunctival and corneal peroxidases are markedly lowered indicating direct or indirect relation of Vitamin A to epithelial functional integrity.

A clinico-investigative profile was studied in 30 patients with Graves' Ophthalmopathy (GO) (15 each with early and late). In accordance to the thyroid status 63.3% of patients were hyperthyroid and 36.7% euthyroid. There was slight female preponderence, with ratio being 1.5:1. Exophthalmometric readings were significantly high in GO patients as compared to controls. However, no significant diagnostic role of postural exophthalmometry was seen. Positional tonometery may have respectable place among the tests for early diagnosis of GO; however, it could not differentiate between hyperthyroid and euthyroid cases. Further the role of ultrasonography, if available could not be overemphasized.

We report three cases of spontaneous extrusion of cysticercosis. In two cases, it got extruded from the orbit and in one case from the subconjunctival space. Extrusion of cysticercosis was associated with improvement in clinical signs and symptoms.

This report is a case of a 4 year old male child who was admitted for meningitis. On clinical examination he was diagnosed as a case of oculo-suriculo-vertebral dysplasia with congenital heart disease, i.e., tetralogy of Fallots besides his presenting picture of meningitis. During his ophthalmic checkup for the conspicuous presence of epibulbar dermoid, he was discovered to have upper lid coloboma, double elevator palsy, and Grade 1 Duane retraction syndrome in his right eye while the pathognomic feature, a dermolipoma, was present in the left eye. The oculo-auriculo-vertebral dysplasia, as described by Goldenhar, is a disease complex of structures developed from the Ist and IInd branchial arch. The important feature of this case is the bilateral involvement of the disease complex over and above the presence of ocular motility disorders--Duane retraction syndrome and double elevator palsy.

A 20 year old female had an angiomatoid malignant fibrous histiocytoma of her left upper eyelid extending into the orbit, frontal and temporal regions. The tumor was excised and radiotherapy was given. Nine months follow-up did not reveal any recurrence.

Presented here are case reports of two patients who became completely blind in both eyes following acute systemic hypotension - in one following bouts of vomiting and in the other after repeated gastrointestinal bleeding. Both patients had severe degree of anemia. There were no other risk factors for vascular disease such as arteriosclerosis or vasculitis.
