Safety and efficacy of Intacs in Indian eyes with keratoconus: an initial report.

CONTEXT: In contact lens-intolerant keratoconus patients, intrastromal placement of Intacs is becoming a promising new modality of treatment. AIMS: To study the safety and efficacy of implantation of microthin corneal inserts (Intacs) in Asian-Indian keratoconus patients. SETTINGS AND DESIGN: Retrospective interventional case series, in the cornea and refractive surgery service, at a tertiary care eye hospital in South India, between May 2006 and July 2007. MATERIALS AND METHODS: Intacs (Addition Technology, USA) were successfully implanted by mechanically creating tunnels, in 12 eyes of 12 keratoconus patients, who were contact lens-intolerant. The patients (mean age 25.58 years, nine male and three female) had a minimum follow-up of six months. Five patients had severe keratoconus (mean K > 53 D) and nine had central cones. RESULTS: All patients improved or retained visual acuity. The uncorrected visual acuity (UCVA) improved from a mean value of 0.06, (SD +/- 0.08) to 0.19 postoperatively (SD+/- 0.15) ( P = 0.01). The change in mean best corrected visual acuity (BCVA) was from 0.51, (SD +/- 0.24), to 0.69, (SD +/-0.00) ( P = 0.01) postoperatively. The average central keratometry reading was 52.55 D. The change in mean K from 52.84 to 49.16 and 49.15 at one and six months respectively, was statistically significant. We did not have any major intra- or early postoperative complications. Eight of 12 eyes became contact lens-tolerant post-surgery. CONCLUSION: The procedure of Intacs implantation appears to be safe and effective in a small group of Indian population at an intermediate follow-up.

Patterns of uveitis in children presenting at a tertiary eye care centre in south India.

PURPOSE: To study the patterns of uveitis in the paediatric age group in a referral eye care centre in south India. MATERIALS AND METHODS: Thirty-one patients 15 years or younger with uveitis, examined in the year 2000, were included in this study. The uveitis was classified according to the anatomical site of ocular involvement and the most probable aetiological factor. The final diagnosis was based on clinical manifestations and results of specific laboratory investigations. RESULTS: A total 31 (6.29%) paediatric uveitis cases were seen among the 493 uveitic cases in the year 2000. The male:female ratio was 17:14. Anterior (9 cases), intermediate (9 cases) and posterior uveitis (9 cases) were seen in equal number. Four patients had panuveitis. Twenty-seven patients had visual acuity of 6/36 or better at presentation. Approximately 25% (8 of 31) patients had cataract secondary to inflammation. Immunosuppressives were administered in 4 patients and one patient required cataract surgery. CONCLUSION: Uveitis in children comprises approximately 6% of uveitis cases in a referral practice in south India. Anterior, intermediate and posterior uveitis are seen in equal numbers. We recommend that intermediate uveitis be ruled out in all cases of anterior uveitis by careful clinical evaluation including examination under anesthesia (EUA) when required.

Recurrent anterior uveitis and healed retinal vasculitis associated with multiple sclerosis.

We describe the occurrence of anterior uveitis with healed retinal vasculitis in an Asian-Indian woman. She had features of anterior uveitis and healed retinal vasculitis. This rare disease in India may be associated with intraocular inflammation.

Current approaches to diagnosis and management of ocular lesions in human immunodeficiency virus positive patients.

Human immunovirus infection in India is rapidly increasing. Ocular lesions due to highly active antiretroviral therapy have been well recognized. Acquired immunodeficiency syndrome can affect all parts of the eye. However, posterior segment lesions are the most common and of these, Human immunodeficiency virus retinopathy and cytomegalovirus retinitis predominate. Often clinical examination can establish the diagnosis of many ocular lesions in acquired immunodeficiency syndrome; therefore, ophthalmologists need to be aware of the more common ones. Various drugs in different routes can used to treat cytomegalovirus retinitis. Highly active antiretroviral therapy has remarkably reduced systemic and ocular morbidity among acquired immunodeficiency syndrome patients. To facilitate care of these patients aseptic precautions for ophthalmic care personnel are now well established and therefore ophthalmologist should not hesitate to provide ophthalmic care to acquired immunodeficiency syndrome patients.
