A case of endogenous fungous endophthalmitis with secondary pupillary block glaucoma and corneal invasion requiring penetrating keratoplasty is reported. Initially Paecilomyces lilacinus was isolated from a vitreous and a lens aspirate, but a second vitreous tap revealed Aspergillus fumigatus and P lilacinus. This case highlights the difficulty of diagnosing endogenous fungous endophthalmitis presenting without risk factors and the difficulties of managing such cases using the antifungous agents available. To our knowledge, this is the first case report documenting a progression to stromal keratitis from endogenous endophthalmitis secondary to P lilacinus.

We analyzed all penetrating keratoplasties performed in the Singapore National Eye Centre from 1 January 1991 to 31 December 1995, using records of the Singapore Eye Bank Registry, evaluating the indications, complications, causes of graft failure, visual outcome and graft survival rate. We also looked into donor cornea acquisition in the Singapore Eye Bank and its influence on the development of corneal transplantation in the Singapore National Eye Centre. A total of 327 penetrating keratoplasties were performed during the 5-year period. Bullous keratopathy was an indication in 26.3% of cases. Of these, aphakic bullous keratopathy accounted for 11.6% of all cases, while pseudophakic bullous keratopathy accounted for 11.3%. Other indications were regrafts (11.9%), corneal dystrophies (10.4%), traumatic corneal scarring (10.1%) and keratoconus (9.8%). Graft rejection was a complication in 20% of all cases. Of these, 40.9% led to graft failure. Other major complications were raised intraocular pressure (18%), epithelium-related problems (7.3%), wound dehiscence (4.3%), cataract (3.3%) and microbial keratitis (3.1%). The main causes of graft failure were graft rejection (8.2%), endothelial failure (2.4%), infection (2.4%) and glaucoma (2.1%). Of the 327 grafts, 40.3% achieved best corrected visual acuity of 6/12 or better; 70.8% achieved vision of 6/24 or better. The overall graft survival rate was 82.3% after a mean follow-up period of 2 years. Donor corneas for the penetrating keratoplasties were obtained from foreign eye banks as well as locally, with the local donation rate steadily increasing from 1991 to 1996, with the establishment of proper eye banking facilities and the Singapore Eye Bank. These results show that the indications and outcome of penetrating keratoplasty in the Singapore National Eye Centre are similar and comparable to that of other centres with established corneal grafting programmes. The establishment of the Singapore Eye Bank has ensured the proper co-ordination of acquisition of donor material which has been vital to the development of corneal transplantation in the Singapore National Eye Centre.

Pigmented fungi were identified in ocular tissues from 2 cats and 1 dog. The first cat was euthanatized because of acute anterior uveitis that was unresponsive to treatment. On histologic examination, intraocular structures had been obliterated and replaced by a gray coagulum of inflammatory infiltrates and fungal elements. The second cat was treated for unilateral glaucoma that was unresponsive to treatment. A large retrobulbar mass, discovered and removed during an enucleation procedure, contained plant-origin foreign material. Keratitis, episcleritis, and orbital cellulitis with fungal elements were found on examination of the enucleated globe. The dog, examined because of a presumed corneal scratch of 2 weeks' duration that was unresponsive to treatment, had a corneal lesion subsequently removed by lamellar keratectomy that contained fungi on histologic examination. Infections caused by dematiaceous fungi are not common in domestic animals, and, to our knowledge, such infections in the eye have not been described.

The relationship between oral contraceptive (OC) use and eye disease was investigated through abstraction of salient data from the two large British cohort studies of the effects of OCs: the Royal College of General Practitioners' (RCGP) OC Study and the Oxford-Family Planning Association (FPA) Contraception Study. Together, these studies have accumulated over 850,000 person-years of observation since 1968 involving 63,000 women. The conditions considered in the analysis were conjunctivitis, keratitis, iritis, lacrimal disease, strabismus, cataract, glaucoma, retinal detachment, and retinal vascular lesions. The only eye disease for which there was consistent evidence of a notable increase in risk in OC users was retinal vascular lesions. The relative risk of retinal vascular lesions in OC users compared to never users was 2.0 (95% confidence interval (CI), 1.0-3.8) in the RCGP data set and 2.4 (95% CI, 0.4-9.2) in the Oxford-FPA Study. This increased risk was not concentrated in any one diagnostic category (e.g., retinal vascular occlusion, retinal vein thrombosis, retinal hemorrhage).

Ocular leprosy is rarely seen in developed countries. We report the long-term follow-up of a patient with bilateral uveitis, glaucoma, and keratitis. Skin, iris and aqueous humor biopsies disclosed abundant Wade-Fite-positive organisms consistent with Mycobacterium leprae. Leprosy must be considered in the differential diagnosis of keratitis and uveitis.

Ocular complications may occur with the use of corticosteroid-containing eyedrops. We describe two cases of corticosteroid-induced glaucoma and one case of corticosteroid-associated fungal keratitis. Corticosteroid-containing eyedrops should be avoided unless the practitioner is knowledgeable about tonometry, slit-lamp examination techniques, and ocular differential diagnosis and treatment. Alternative pharmacologic approaches to topical administration of corticosteroid-containing eyedrops are discussed.

Flap complications using first-generation microkeratomes, such as the Automated Corneal Shaper, were reported in 2.5% (27 of 1,062 eyes). With modern microkeratomes, such as the Hansatome, keratotomy-related complications dropped to 0.16% (46 of 28,201 eyes). Postoperative flap complications, such as flap slippage, occurred in 1.42% (21 of 1,418 eyes), most of them during the first hour after surgery. Interface complications are a new diagnostic entity as the interface between flap and stroma presents an empty space where fluid or cells can accumulate. Diffuse lamellar keratitis usually occurs within the first postoperative days but may also develop later on, triggered, eg, by recurrent corneal erosion. Epithelial ingrowth is a rare complication caused rather by postoperative invasion than by intraoperative implantation, which suggests that the quality of the flap edge and its apposition are very important. Interface fluid is a rare but important phenomenon related to steroid-induced glaucoma but presenting with falsely low tonometry readings.

Anecdotal case reports describe the occurrence of cystoid macular edema, iritis, herpes simplex keratitis, periocular skin darkening, and headaches in patients treated with prostaglandin analogs for glaucoma. The purpose of this article is to critically analyze these anecdotal case reports in light of a few well-controlled, randomized clinical studies to determine whether conclusions can be made about a causal relationship between the use of prostaglandin analogs and the occurrence of these side effects. None of these putative side effects has been proven to be causally related to latanoprost therapy using valid scientific methodology. These possible side effects occur rarely. Cystoid macular edema, iritis, and herpes simplex keratitis occur in eyes with risk factors. To scientifically establish a causal relationship between drug therapy and rare side effects, repeated rechallenging with masked controls is required. With rare exception, such methodology has not been used with any of these putative side effects. Nevertheless, even without firm establishment of a causal relationship, caution is advised with the use of prostaglandin analogs in eyes with risk factors for cystoid macular edema, iritis, and herpes simplex keratitis until properly designed, large, controlled studies provide more definitive information.

The PAX6 mutation present in an individual with aniridia was determined and phenotypic features of immediate relatives carrying the same mutation investigated. Mutation analysis revealed a novel single base deletion 1410delC in the PAX6 gene in ten affected individuals. Clinical features ranged from total aniridia to very mild anterior segment findings. Other findings included partial aniridia, iris stromal hypoplasia, keratitis, cataract, glaucoma, optic disc anomalies and foveal hypoplasia. It appears that independent modifying factors may underlie the variability of the different phenotypic features of the PAX6 mutation.

Because of the wide variety of x-rays now available, selectivity is possible and important in treatment of diseases of the eye. By the use of short-range radiation, newly developed eye shields and the insulation of the eyelid itself, and by careful angulation of the beam, the desired irradiation can be given where it is needed without injury to surrounding tissues. The authors have found the 50 kv x-ray unit to be the most reliable and adaptable for most circumstances. The skin of the eyelid reacts to irradiation more sensitively than other tissues. The cornea reacts with keratitis and sometimes intractable ulceration. The iris, uveal tract and retina are less seriously affected. At the University of California Hospital irradiation has been found satisfactory for treatment of corneal ulcer, keratitis, pterygium, certain types of conjunctivitis, episcleritis, corneal vascularization, iritis, uveitis, and hemangioma. Irradiation may be of great benefit in absolute glaucoma with pain and blindness. Of 42 patients with carcinoma of the eyelid treated between 1935 and 1946, 27 had no recurrence in five years, 5 had recurrence, 7 died of other causes and follow-up was incomplete on 3. Good cosmetic result was usually achieved. No recurrence has been observed in 22 patients treated since 1946. Irradiation has been used with success in other kinds of cancer of the eye structures.
